British Isles weather, January 2017

Rainfall moved SE'wards on the 1st overnight and during the day across Ireland, England and Wales; across Ireland it turned brighter with sunny spells during the day - but in England and wales a rather cloudy day ensued. There was some early air frost in parts of Scotland - these were followed by some outbreaks of rain and showers, especially in N and E areas of Scotland with some of the showers turning to snow. Some snow also fell over high ground in Cumbria and N Wales. (Swanage 11.3C, Carterhouse 2.2C maximum, Drumalbin -1.5C minimum, St Catherines Point 18.4 mm, Cork Airport 6.9 h.)

High pressure was centred to the W of the British Isles on the 2nd, MSL pressure being about 1034 mb in NW Ireland at 0000 GMT. The day began with a widespread ground frost and air frost in places, the latter especially over Scotland and Ireland. Cloudier conditions overnight in parts of N Scotland were accompanied by a few snow showers. During the day these showers turned to rain and drizzle and a few falls of rain were also to be found on N-facing coasts in other parts of the British Isles. Away from N Scotland it was a mostly sunny day and it was also cold in some areas. (Port Ellen 7.8C, Spadeadam -0.1C maximum, Shap -5.3C minimum, Resallach 11.8 mm, Camborne 7.4 h)

Air frost was widespread south of a line Dublin-Hull on the 3rd, with an early ground frost in N England and S Scotland. A N'ly flow drew fronts S'wards across Scotland during the day with falls of rain and drizzle here, and later in N Ireland, as a result. Away from S areas of Ireland and England it was a largely cloudy day, becoming windy in N Scotland later. (Drumnadrochit 10.4C, High Wycombe 3.3C maximum, Exeter Airport -6.8C minimum, Resallach 18.8 mm, Camborne 7.6 h.)

Fronts pushed SW'wards over S parts of the British Isles during the 4th, although resulting falls of rain tended to be rather slight in most places. Cloudy skies tended to suppress any air frost formation overnight - while during the day the best of the sunshine tended to be found in N and E areas of England. Across N Scotland there were a few snow showers overnight and during the day. (Usk No.2 10.5C, Dalwhinnie 2.0C maximum, Otterbourne Water Works -2.0C minimum, Lerwick 3.2 mm, Morecambe 6.1 h.)

Although pressure was generally high on the 5th (1035 mb over SE Wales at 1200 GMT) frontal cloud to the W of the British Isles later pushed E'wards across much of Scotland and Ireland. There was a widespread air frost, except across S Ireland and SW England, at first and most places then had a dry and sunny day ahead of the rain that spread into the W later. Widespread mist formed over S and Cent England in the evening, and a few snow showers fell over the Northern isles in the morning. W Ireland and some N parts of Scotland remained rather cloudy. (Isles of Scilly 11.0C, Strathallan 0.5C maximum, Tyndrum -8.2C minimum, Tiree 1.8 mm, Wellesbourne 7.1 h.)

Frontal cloud and rain spread generally E'wards during the 6th across all areas, with generally misty conditions being reported when the rain and drizzle ceased. Much of England and SE Scotland had an air frost ahead of the cloud and the rainfall was especially heavy across parts of Ireland; in Valentia 31mm of rain fell in the 12 hours ending 0600 GMT. Only the Channel Islands and a few locations in SE England reported in excess of one hour of bright sunshine, while in parts of E England it was a rather cool day. (Finner and Valentia 12.2C, Fylingdales 3.2C maximum, South Newington -6.7C minimum, Dundrennan 33.4 mm, Odiham 2.2 h.)

The 7th was a mainly cloudy and mild day in all areas, except for a few places in E Scotland where it stayed cold. Overnight rain was largely confined to England and Wales, and these conditions were followed by widespread mist and a few fog patches during the day here. Further mist and fog formed in parts of Ireland and Scotland later while air pressure remained generally high during the day. (Exeter Airport 12.1C, Balmoral 1.7C maximum, Kinbrace -3.5C minimum, Bude 11.4 mm, Eskdalemuir 3.0 h.)

A warm sector developed across the British Isles on the 8th leading to a rather mild and cloudy day in most areas. Parts of E Scotland and NE England had a slight air frost at first, while mist and fog was widespread by dawn across England, Wales and Ireland. At Topcliffe the fog and cold led to a few snow grains falling. These conditions persisted for much of the day across England as light rain spread across most areas from the W. Few places, away from the E coast of NE England and E Scotland, had any sunshine during the day although temperatures widely reached 11C. (Swanage 12.9C, Fyvie Castle 6.2C maximum, Aboyne -1.9C minimum, Lusa 9.2 mm, Morpeth Cockle Park 4.7 h.)

A low pressure system moved from W of Scotland to the N of Scotland during the 9th bringing spells of frontal rain to all areas. The day dawned with mist and fog across many parts of England, after a generally mild night in all areas. As the rain cleared towards the E showers, some of them wintry in N Scotland, followed - and there were rather windy conditions at times during the day in W and N parts of the British Isles. The best of the sunshine was to be found across Scotland and Ireland, where the showery conditions prevailed. (Isles of Scilly 11.0C, Killylane 3.8C maximum, Drumnadrochit 2.3C minimum, Achnagart 46.4 mm, Kinloss and Dublin Airport 4.9 h.)

The 10th was a showery day in many W areas, ahead of a low pressure system that lay (centre 971 mb) just to the NW of Scotland by 2400 GMT. The rain was particularly widespread across Scotland and N Ireland overnight, with lesser falls elsewhere during the night and also across Scotland during the day. Away from E parts of England and Scotland it was a rather dull day, while some heavier rain fell in parts of Scotland in the evening. (Isles of Scilly 11.6C, Spadeadam 6.4C maximum, South Newington 0.9C minimum, Cluanie Inn 19.6 mm, Manston 4.5 h.)

The 11th was a blustery day, especially across Scotland where gust reached 65-75 mph in places. Cold fronts rapidly crossed the British Isles during the morning introducing showery air to all area, with the showers being most widespread across Scotland where they fell as snow in places. Some snow also fell over high ground in Cumbria. (Shoreham 12.3C, Dalwhinnie 2.2C maximum, Dalwhinnie 1.1C minimum, Altnaharra 26.4 mm, Charterhall 5.5 h.)

A deepening area of low pressure moved E'wards along the English Channel during the 12th. There was an air frost across parts of Scotland although many places here had some overnight rainfall. Rain spread across most of Wales, S England and the Midlands, moving away to the E; it turned to snow for an hour or two in many places, leading to a few centimetres of lying snow in places. The snow led to some school closures in parts of Wales. It was a cloudy day across England, Wales and S Ireland but brighter with some sunshine further N. This latter area had some snow and hail showers as a N'ly flow developed - along with some isolated thunder. It also turned windy in N areas. According to Bob Prichard, the marginal nature of the snow in the southeast (with respect to altitude and proximity to central London) in the evening is illustrated by the following: Putney 'sleety rain', Claygate 75min of heavy snow (3 cm on ground, then thawing to 1cm quite quickly); Banstead still a few centimetres of snow on ground midday 13th. (St Helier 9.4C, Dalwhinnie -0.5C maximum, Aviemore -1.9C minimum, St Catherines Point 31.6 mm, Dyce 5.7 h.)

A N'ly flow on the 13th led to a cold and blustery day after a widespread air frost across the UK. Snow showers fell in many areas, especially across Scotland and in coastal areas - but also as far inland as the Midlands. It tended to be cloudier near to the W- and E-facing coastlines but most places had sunny spells in between the showers. Warnings of a storm surge and subsequent flooding as a result of a high tide and the N'ly flow led to some evacuations along the E coast of England - but most areas avoided any flooding , with the Environment Agency saying a change in wind direction helped avert flooding. (Isles of Scilly 7.7C, Dalwhinnie -0.2C maximum, Drumalbin -4.5C minimum, Kinlochewe 30.0 mm, Morecambe 5.6 h.)

There was a widespread air frost on the 14th except close to W coast areas of the UK and in S and Cent Ireland. Showers, some of them wintry, fell overnight in Ireland and over W parts of the UK with the most of the snow falling over Scotland. During the day snow largely turned to rain with a band of rain moving SE'wards W Scotland. Further rain, with snow over the hills, moved SE'wards across Scotland and into N parts of England and Wales in the afternoon and evening. It was a sunny day in many parts of E Scotland and E England. (Isles of Scilly 9.7C, Loch Glascarnoch 0.5C maximum, Drumnadrochit -6.0C minimum, Altnahinch Filters 24.0 mm, Leconfield 7.1 h.)

The Shetland Islands had some snow showers overnight into the 15th with some rain or drizzle affecting mnay other parts of the British Isles before dawn. A warm front spread more rain E'wards during the day - with rainfall totals during the day being largest over Cent and E England and in parts of Scotland. As the rain cleared from the W here it turned foggy over E and Cent areas of England. (Cardiff Bute Park 11.9C, Weybourne 3.0C maximum, Santon Downham -3.5C minimum, Loch Glascarnoch 55.2 mm, Boulmer 1.0 h.)

Fronts continued to spread cloud and rain from the W across England overnight into the 16th, before becoming slow-moving over E England later in the day. East Anglia, ahead of the rain, consequently had a cold day while to the W of the rain temperature widely rose to 10C. The frontal rain and drizzle weakened in intensity as the day developed - but it remained rather misty in many N and E areas of England for much of the day. Except in a few parts of E Scotland it was a largely dull day. (Achnagart 11.7C, Wych Cross 3.3C maximum, Manston 0.0C minimum, Winchcombe Sudeley Castle 11.6 mm, Leuchars 3.5 h.)

There was widespread mist and fog across England Wales and Cent Ireland into the 17th - with a slight air frost in places to the S and SE of London. A rather cloudy day followed, except in parts of SE England and the S part of East Anglia - as a weak front moved slowly W'wards across Cent England into Wales and SW England. It was mild to the W of the front which gave falls of light rain and drizzle; further rain also fell in parts of W Scotland and E Ireland. (Aboyne 13.2C, Langdon Bay 1.5C maximum, Santon Downham -2.2C minimum, Machrihanish 5.2 mm, Jersey Airport 7.5 h.)

Despite prevailing high pressure on the 18th a slow-moving front led to rain and drizzle in places W of a line Hull-Bristol during the day. Earlier, there was a sharp air frost in parts of East Anglia and SE England. Mist and fog patches were widespread across England and Wales at dawn - and these persisted all day in places, reforming in Cent parts of England in the evening. Parts of NE Scotland and much of S England had a sunny day - elsewhere it was rather dull. (Tain Range 11.9C, Wych Cross 2.0C maximum, Frittenden -7.1C minimum, Lusa 5.0 mm, Jersey Airport and Guernsey Airport 7.9 h.)

After an air frost across much of SE and Cent S England, the 19th was a mostly dry day. Mist and fog was widespread over Cent England at dawn and this then persisted throughout the day, giving a little drizzle in places. S England, W Ireland and E Scotland had a sunny day - elsewhere it was a dull day, especially where the mist and fog lingered. It was a mild day across Scotland and Ireland in a W'ly flow, colder elsewhere under the high pressure area. (Valentia 11.6C, Wych Cross 4.2C maximum, South Farnborough -6.2C minimum, Harris Quidnish 2.6 mm, Camborne 8.3 h.)

Mist and fog over Cent and E England cleared during the morning of the 20th but remained all day in parts of N England, Ireland and E Scotland. Parts of E Scotland, and much of S and Cent England had an air frost before dawn. It remained largely dry under the area of high pressure during the day, with long spells of sunshine across Wales, S and Cent England and S Ireland - and also over much of mainland N Scotland. Some drizzle fell in places over N England, N Ireland and S Scotland. (Valley 10.0C, Balmoral 1.6C maximum, South Farnborough -7.2C minimum, Lough Fea 0.8 mm, Aberporth 8.0 h.)

Many inland areas had an air frost on the 21st, with minimum temperatures below -6C in parts of Cent S England. Many E areas of the K had a misty start to the day before cloud and some light drizzle spread from Norfolk across N areas of England and Wales. Some rain fell in the evening over Scilly but, away from the rain and drizzle, most places had long sells of sunshine - although a few places in E Scotland remained rather foggy for much of the day. (Bridgefoot 9.1C, Altnaharra -0.6C maximum, South Farnborough -8.1C minimum, Isles of Scilly 1.2 mm, Valley 7.6 h.)

Ground frost was widespread into the 22nd with air frost being recorded over much of England and Wales (apart from the extreme N and SW) and in N Ireland and many Cent areas of Scotland. In S Scotland S'wards mist and fog patches were widespread by dawn - and these led to snow grains falling in places in the cold air. During the day there was some light rain and snow over parts of Wales, the Midlands and N England. However, amounts of precipitation were small and parts of Ireland and Cent S and SE England had long spells of sunshine. Mist and fog, freezing in places, formed widely in the evening except over N Scotland. (Isles of Scilly 10.8C, Fylingdales 0.0C maximum, South Farnborough -8.0C minimum, Culdrose 4.6 mm, Jersey Airport 7.9 h.)

Freezing mist and fog was widespread by dawn in most places S of Cent Scotland on the 23rd. The fog persisted all day in places with remaining areas staying rather misty. Later in the day a little rain spread into W Ireland and some light rain also fell in parts of N England and the NE Midlands. It was a mostly cloudy day but some places close to the Irish Sea had long sunny spells. Mist and fog thickened widely in the evening. Flights were cancelled at London airports because of early freezing fog covering much of southern England. About 100 flights were affected at Heathrow; London City cancelled 88 flights and Gatwick cancelled nine flights. A total of 39 flights were cancelled at Southampton airport. The cold weather has also meant parts of the UK were suffering from high levels of air pollution. Dorset Police reported 31 weather-related collisions on Monday morning - six times more than would occur at that time on an average weekday. (Isles of Scilly 11.1C, Herstmonceux 0.9C maximum, Katesbridge -7.1C minimum, Fair Isle 1.4 mm, Bude 7.9 h.)

Many areas again had a mist or fog at dawn on the 24th with much of England and E Scotland having an air frost. Rain spread across Ireland overnight and affected some W areas of the UK later. The fog persisted all day in parts of North Yorkshire, the SW Midlands and Cent S England. 13 mm of rain fell at Valentia in the 12 hours ending 0600 GMT and as the cloud and rain spread E it turned warm (10C and above) in Ireland and W parts of the UK. Where the fog cleared it was a sunny day in E England. About 100 flights were been cancelled at London's Heathrow Airport for a second day because of fog. Drivers were urged to take care on the roads and ferries running to and from the Isle of Wight between Lymington and Yarmouth have been suspended until mid-morning on Tuesday due to dense fog, Wightlink Ferries said. (Achnagart 12.0C, Hurn 2.5C maximum, Shobdon -5.3C minimum, Tyndrum 8.6 mm, Guernsey Airport and Wattisham 7.5 h.)

The 25th was a mild day across Scotland and Ireland, but cooler elsewhere. The Midlands, East Anglia, Cent S and SE England had an early air frost with mist and fog overnight; elsewhere there were a few scattered spots of mainly light rain. The fog persisted into the afternoon in places, especially in parts of East Anglia and the N Midlands. Frontal rain reached W Ireland later in the day with Valentia recording 19 mm of rain in the 24 hours ending 1800 GMT. It was a sunny day across Wales, N England and SE Scotland but rather cloudy elsewhere. In a few places the freezing fog led to falls of snow or snow grains. (Altnaharra 13.3C, Langdon Bay 1.1C maximum, Exeter Airport -5.5C minimum, Eskdalemuir 4.8 mm, Aberporth 7.9 h.)

There was rain in W Ireland overnight into the 26th (14 mm at Valentia in the 12 hours ending 0600 GMT) but this made little progress E during the day. Elsewhere the day was mainly dry - SE Scotland much of E and Cent England, and E Wales, had an air frost with temperatures in many parts of England then failing to reach 0C by 1800 GMT in rather misty conditions; elsewhere in England and Wales it was also a cold day, away from the extreme W areas. Cloudy skies led to a few flurries of light snow - but it was a mild day in NW Scotland. (Aultbea 13.4C, Leek -2.2C maximum, Redesdale Camp -4.9C minimum, South Uist 0.4 mm, Valley 7.7 h.)

Mist and fog patches were quite widespread across the UK by dawn on the 27th and except in some N and Sw areas there was a widespread moderate to severe frost overnight. Milder air moved N'wards during the day, but temperatures remained below 0C in some parts of E Scotland and N England. Rain spread across Ireland and into W areas of the UK and the best of the sunshine tended to be found in Cent and S Scotland. In the evening rain and drizzle moved across much of Englabd ad Wales - with sleet or snow over higher ground. (Kinlochewe 11.4C, Strathallan -0.7C maximum, Braemar -7.3C minimum, Isles of Scilly 21.6 mm, Aviemore 5.7 h.)

There was little air frost on the 28th and most areas had a spell of rain during the day (except in parts of East Anglia and SE England. Rain, with snow in places, continued over much of Scotland through the day - clearing slowly from the SW later - whilst N Ireland, Wales and England had a mix of sunshine and showers; there was also some thunder in places in the London area in the afternoon. (Northolt 11.1C, Balmoral 1.3C maximum, Spadeadam -2.2C minimum, Porthmadog 19.6 mm, Yeovilton 6.2 h.)

Rain pushed N'wards across Scotland during the 29th. Further S there was aa little air frost in places and a few patches of mist or fog. Scotland and N Ireland then had a bright or sunny day but elsewhere it turned cloudy as frontal rain moved N'wards - with some heavy falls in places later over Wales and S England. (Exeter Airport 12.0C, Balmoral 2.8C maximum, Katesbridge -5.3C minimum, Swanage 22.8 mm, Kinloss 7.5 h.)

Overnight into the 30th there was a severe air frost in parts of Scotland and N England, followed by a bright day. Further S fronts led to a cloudier night with rain, drizzle, mist and fog by dawn. In SW and Cent S England rain was more prolonged, but generally light, with much of the S half of England having a misty day. Rain spread E'wards over Scotland later in the day with falls also in N Ireland and N England. (Bude 12.4C, Strathallan 2.0C maximum, Braemar -10.1C minimum, Hurn 6.0 mm, Kinloss 6.2 h.)

The 31st was a rather cloudy or dull day, generally. Overnight, mist with rain or drizzle was prevalent across much of England and Wales - with outbreaks of rain also across Scotland and Ireland. Mist and fog particularly affected the hillier areas of England and Wales, along with some exposed coastal areas in the S'ly flow. Drier weather moved across from Ireland into W and N Scotland. A narrow warm sector led to a mild day in the W and N, while it remained cold in the E and NE. (Trawscoed 12.9C, Fylingdales 4.0C maximum, Lentran 0.5C minimum, Gt Cumbrae Millport 31.2 mm, Magilligan 2.2 h.)

British Isles weather, February 2017

There was some ground overnight into the 1st across Ireland and a slight air frost in parts of N and Cent Scotland while fronts gave widespread rain across most of Wales and England overnight. Fog was widespread around dawn in N Ireland and in parts of E Scotland. The day was generally mild and cloudy with misty conditions persisting close to the North Sea under the influence of weak fronts. There was further, mainly light, rain and drizzle in parts of Wales and England during the day - while more general rain spread into S Ireland and SW England later in the day as a deep low headed towards Ireland. Valentia reported MSL pressure close to 978 mb at 2400 GMT. (Chivenor 12.6C, Inverbervie 6.6C maximum, Altnaharra -4.5C minimum, Fylingdales 18.8 mm, Kinloss 4.1 h.)

A deep area of low pressure tracked N'wards to the W of Ireland during the 2nd, pushing a series of fronts E'wards across the British Isles during the day. Overnight there was a slight ground frost in E Scotland and outbreaks of rain in Ireland, W Scotland, Wales and England. There was further rain in these areas during the day, although E Britain remained largely dry. The day was a blustery one, with very little sunshine. (Gogerddan 14.0C, Inverbervie 8.2C maximum, Cassley 2.8C minimum, Whitechurch 24.6 mm, Manston 2.3 h.)

Areas of low pressure lay close to W Ireland and, later to S England, on the 3rd. Rain and showers affected the W half of the British Isles overnight and during the day fell across Wales and W parts of the UK. An area of more general rain later moved NE across much of S England and later Cent and N areas of England. As a result sunshine was mainly confined to Scotland and E areas of England. Clearer weather moved into S England during the evening. (St James Park 11.8C, Lough Fea 5.1C maximum, Lake Vyrnwy 3.1C minimum, Scolton Country Park 33.8 mm, Boulmer 6.9 h.)

There was a widespread ground frost into the 4th across Ireland, Wales and in S and Cent areas of England with places close E Wales having a slight air frost. Rain in N England moved N'wards into Scotland. Later in the day rain spread NE across S England. The rain across Scotland was accompanied by snow over high ground. (Plymouth 10.2C, Dalwhinnie 2.5C maximum, Shawbury -2.8C minimum, Achnagart 36.6 mm, Leconfield 8.0 h.)

Low pressure, centred close to S England on the 5th gave a wet day over the Channel Islands; 41 mm fell at Jersey Airport in the 12 hours ending 1800 GMT. Ground frost was widespread overnight with an air frost in many places, especially across Ireland. After overnight rain in some W and S areas of the UK, much of England and N Ireland dawned with mist and fog patches. Further rain fell during the day across Scotland while Ireland and Wales had a sunny day. Temperatures were below normal in many areas, while the mist lingered throughout the day in many parts of England. (Isles of Scilly 9.9C, Killylane 2.0C maximum, Katesbridge -5.6C minimum, Tiree 14.6 mm, Magilligan 5.9 h.)

High pressure overnight into the 6th resulted in a widespread air frost across the UK and the N half of Ireland. Mist and fog was again widespread across many parts of England and E Scotland by dawn, but frontal rain spread into SW Ireland by dawn with 10 mm falling in some place in the 12 hours ending 0600 GMT. The fog was slow to clear from parts of NE and E England; elsewhere frontal cloud and rain spread from the SW, with falls of snow over some high ground in N Britain. It turned windy in NW Scotland with gusts of over 70 mph in some exposed parts - across Ireland and SW England the temperatures rose as the rain arrived. Most places, except those in E Scotland and E England, had a dull day. (Shannon Airport and Valentia 13.3C, Pennerley 2.9C maximum, Topcliffe -6.2C minimum, Threave 16.0 mm, Kinloss 5.3 h.)

Fronts led to a rather cloudy day on the 7th across much of Scotland, N and E England. Rain and drizzle was widespread overnight with further falls, especially across Scotland where snow also fell in places, during the day. Mist and fog had formed by dawn in parts of England and this was to linger all day in some E areas. It was a cold day in E Scotland, but quite mild in parts of the Midlands and Cent S England. (Pershore College 12.6C, Dalwhinnie 1.9C maximum, Dalwhinnie 0.0C minimum, Craibstone 38.0 mm, Brize Norton 6.4 h.)

Winds blew from the E in E areas of the UK on the 8th, but were more S'ly in W Ireland. The dawned with some fog patches after overnight patchy rain and drizzle across England and E Scotland, while air frost was widespread over Ireland and in W Scotland. The day was generally cool with some light rain or drizzle in places in much of England and E Scotland; further W there were sunny spells. It was generally warmest in these W areas. (Milford Haven 11.1C, Fylingdales 1.9C maximum, Katesbridge -5.3C minimum, Craibstone 11.8 mm, Bude 8.1 h.)

An E'ly flow gradually became established across most areas of the British Isles on the 9th as MSL pressure rose to 1036 mb over Shetland by 2400 GMT. Way from SW Cornwall and the extreme W of Ireland a cold day was the result. Near E and NE coasts there were some slight falls of rain or drizzle, with light snow in places. It was a cloudy day in most places, although there were sunny spells in W Scotland and in parts of W Wales. (Valentia 9.8C, Lake Vyrnwy -0.4C maximum, Shap -3.7C minimum, Morpeth Cockle Park 3.2 mm, Bude 8.3 h.)

The E'ly flow persisted during the 10th. The day was mostly cloudy and very cold with outbreaks of mostly light drizzle or snow in many areas, after a slight air frost in some places. There were some brighter intervals, and it was quite sunny over N Scotland and in areas of NE Wales. In some parts of England temperatures failed to reach 2C. (Valentia 8.7C, High Wycombe 0.2C maximum, Altnaharra -5.2C minimum, Fair Isle 6.0 mm, Kinloss 6.5 h.)

Early ground frost was widespread on the 11th, and sharp over NW Scotland, while many inland areas also had an air frost - slight in most places by quite sharp in N Scotland. Light rain, drizzle and snow blew into many areas of the UK from the E during the day, after overnight falls in E areas; light snow fell as far W as E Ireland. Some heavy rain with snow on high ground, fell over NE England and SE Scotland. In many parts of England temperatures failed to reach 3C. (Belmullet 7.7C, Okehampton -0.1C maximum, Altnaharra -9.8C minimum, Fylingdales 25.2 mm, Tiree 7.8 h.)

High pressure centred to the W of Scotland gradually retreated E on the 12th allowing Scotland to come under the same E'ly flow affecting more S'ly areas. The day was mostly dull and cold with only N and W Scotland seeing much sunshine. A weak front pushed areas of rain, and some snow, NW'wards during the day with more of a (slightly milder) SE'ly flow then following across SE areas of the UK. (Lerwick 6.9C, Pennerley 0.5C maximum, Altnaharra -8.9C minimum, Fylingdales 9.8 mm, Lerwick 7.9 h.)

The 13th dawned with widespread mist and haze across England and Wales following a night with slight outbreaks of rain and wintry weather along NW'ward-moving fronts. As these weakened most places, away from E and NE Scotland, had a day with sunny spells although the reduced visibility across England and Wales, and later E Scotland, was rather persistent. (Chivenor 13.4C, Balmoral 3.0C maximum, Drumnadrochit -0.9C minimum, Carterhouse 4.4 mm, Morecambe 8.6 h.)

A SE surface flow turned to a milder S'ly direction on the 14th as fronts pushed N'wards from SW parts of Ireland and the UK during the day. After a cold night (although with an air frost in only a few places) rain and drizzle became widespread by dawn across S Ireland and Cornwall. This precipitation spread NE during the day but falls were mainly slight - indeed, much of Scotland and many parts of E England had a sunny day. By the evening it had turned milder in SW England and S Ireland - while the extreme W of Scotland had a warm day in the sunshine here. By late evening fog was widespread in S Wales and SW England. (Lusa 14.0C, Lake Vyrnwy 3.8C maximum, Drumnadrochit -4.5C minimum, Plymouth 9.2 mm, Kinloss 8.1 h.)

Low pressure to the W of the British Isles and several fronts led to a rather dull day on the 15th, although places from NW to SE Scotland had some sunny spells. Parts of NE Scotland had a slight air frost at first although in S parts of Ireland, Wales and England overnight minimum temperatures were around 6-8C. Away from N Scotland mist and fog were a problem by dawn while overnight rain was largely confined to SW parts of England and Ireland. During the day the rain became more widespread across Ireland, Wales and England - with some snow on the Pennines and N Wales. By midnight patchy rain had also affected many parts of Scotland, except for the NE. (Donna Nook 13.9C, Dalwhinnie 7.2C maximum, Loch Glascarnoch -2.7C minimum, Scampton 14.2 mm, Dyce 7.1 h.)

Rain fell overnight into the 16th across Scotland and parts of Ireland, while mist and fog was widespread around dawn over S England. Frontal rain affected much of Scotland, Ireland and other W areas of the UK during the day - with falls later in some Cent and S areas of England. It was rather cloudy across Ireland and in many W areas of the UK - although there were long sunny spells in some W and SE areas of England. Mist reformed in SW England in the evening and it also turned foggy in the Channel Islands. (Plymouth 13.1C, Spadeadam 6.9C maximum, Exeter Airport -1.2C minimum, Achnagart 30.8 mm, Bude 6.7 h.)

NE'ward-moving fronts during the 17th gave a rather dull day over Ireland and in neighbouring areas of the UK - but there were bright spells elsewhere. E and Cent Scotland began the day with an air frost but during the day temperatures rose to 10-12C in most areas of the British Isles. There was some rainfall in areas close to the N end of the Irish Sea overnight while mist and fog was widespread in many areas of the UK by dawn. These soon cleared and many places in England and Wales had some light rain or drizzle at times during the day; SW Ireland had some heavy rain later in the day with 12 mm falling at Cork Airport during 0600-1800 GMT. (St James Park 13.8C, Eskdalemuir 6.7C maximum, Braemar -3.0C minimum, Warcop 5.0 mm, Dyce 7.8 h.)

Fronts again gave spells of light rain and drizzle to many areas on the 18th with falls mainly across Ireland and W Scotland overnight, and then over much of Scotland during the day. Mist and fog was widespread by dawn across much of England and E Ireland; this was thick on places and many places remained misty throughout the day - with thick fog reforming in the evening in parts of S England. It was, however, quite a sunny in S England and the Channel Islands. (Hawarden 15.1C, Langdon Bay 7.2C maximum, South Newington 0.7C minimum, Achnagart 22.8 mm, Jersey Airport 9.2 h.)

Fronts moved E'wards in a W'ly flow across most parts of the British Isles on the 19th. The day dawned after a mild night in many areas although there was some air frost and patchy fog in S England. There was some rain overnight across Scotland and Wales while Cent and S England were rather misty overnight. Rainfall amounts during the day were generally slight with the heaviest falls over W-facing coastal areas - particularly in Wales and Ireland. Places along the E coast of England and Scotland saw sunny periods; elsewhere, the day was dull. (Fyvie Castle 13.9C, Spadeadam 8.2C maximum, Shoreham -2.1C minimum, Cluanie Inn 8.8 mm, Boulmer 7.8 h.)

Following a warm night (minimum temperatures widely 8-10C overnight) the 20th was a mild day, being unusually mild in parts of England for the time of year. This was the result of a warm sector across S areas in particular. Rain was widespread overnight and during the day across many parts of Scotland - an area of rain then pushed SE'wards across places to the S as a cold front moved towards S areas. Most places had sunny periods during the day, but it was quite a sunny day in some SE areas of Scotland. However, there was thick fog all day over the Channel Islands. (Northolt 18.3C, Lerwick 8.0C maximum, Fylingdales 6.8C minimum, Cassley 29.2 mm, Leuchars 7.5 h.)

The 21st dawned with mild air across S parts of the British Isles and just a slight ground frost in places further N. Spells of rain and drizzle largely affected N and Cent Ireland, W Scotland and W areas of the British Isles. Away from parts of E England it was a dull day - following a rather misty start across Ireland and SW England. (Hereford 14.7C, Fair Isle 7.7C maximum, Katesbridge 0.1C minimum, Cassley 43.2 mm, Leconfield 4.1 h.)

Away from N and Cent Scotland the 22nd dawned after a mild night, with overnight minimum temperatures of 10-11C across S Ireland and S and Cent parts of Wales and England. Cold fronts pushed slowly S'wards during the day before slowing their progress over S England as a wave depression formed close to SW Ireland. Rain was widespread overnight across Scotland, Ireland and N England; amounts lessened during the day across Scotland with the heaviest rain across Ireland and Cent parts of England and Wales during the day. Lesser amounts of rain and drizzle affected other areas of England during the day. Thundery showers with hail affected parts of N Scotland during the morning although there were sunny periods here, and in NE England, during the day; elsewhere the day was generally dull. (St James Park 14.8C, Dalwhinnie 4.7C maximum, Loch Glascarnoch 1.3C minimum, Capel Curig 34.2 mm, Dyce 8.4 h.)

An area of low pressure crossed N Ireland and N England during the morning of the 23rd (MSL pressure centred at 976 mb off the N Yorkshire coast at 1200 GMT). This system, storm Doris, underwent explosive cyclogenesis during its life cycle. Reported gusts due to the storm included Capel Curig 94 mph, High Bradfield 87 mph and Lake Vyrnwy 83 mph; many other places close to the low pressure track reported gusts of 50-80 mph. The storm was blamed for the deaths of two people and the strong winds led to flight cancellations and road and rail disruption across much of the UK. Thousands of homes were left without power; about 23,000 homes and businesses were without electricity in Northern Ireland after trees fell on overhead lines. Energy company SSE said about 700 customers had experienced power cuts in Scotland, mainly in rural Perthshire, Kinross, Dunblane and Milnathort, as a result of heavy snow damaging its overhead network. Highways England closed the Dartford Crossing linking Kent and Essex, the Orwell Bridge on the A14 in Suffolk and the M48 Severn Bridge; the M80 later reopened after earlier closures in both directions due to snow. Aer Lingus cancelled 19 of its 111 flights between the UK and the Republic of Ireland and gale-force winds led to the cancellation of ferries and flights between the Isle of Man and the UK. Speed limits of 50mph were imposed on several train lines affecting Arrival Trains Wales, Chiltern Railways, East Midlands Trains, Grand Central, Great Northern, South West, and Southeastern services. Storm Doris also halted filming on the set of ITV soap Coronation Street, with a spokeswoman saying the weather had made outdoor filming "impossible" and it would have to be rescheduled. However, the Environment Agency said it had not issued any flood warnings for the UK. As the storm passed it led to a developing flow from the NW in the evening. Rain moved NE across much of the British Isles overnight, followed by showers from the W. Over N England and S and E areas of Scotland the rain took longer to clear - and turned to snow over higher ground. Showers followed in the NW'ly flow with snow in places. To the N of the low there was an air frost in N and Cent Scotland while minimum temperatures overnight were close to 10C across many parts of S and Cent England; however maximum temperatures in these latter areas were similar to the overnight minima. The best of the sunshine was to be found across S Ireland and the Channel Islands. (Frittenden 13.2C, Salsburgh 1.3C maximum, Loch Glascarnoch -1.3C minimum, Capel Curig 46.4 mm, Guernsey Airport 7.2 h.)

There was an air frost across NE Scotland on the 24th with a widespread ground frost elsewhere. After a few showers overnight, precipitation in a blustery SW'ly airflow tended to be confined to Scotland and N Ireland - although falls later affected Wales and N and W areas of England. Across Scotland the rain was preceded by snow in places. Away from Ireland and W Scotland, where frontal cloud prevailed for most of the day, there were sunny spells - especially in E and S districts. (Isles of Scilly 11.0C, Dalwhinnie 2.6C maximum, Altnaharra -5.7 C minimum, Cluanie Inn 13.2 mm, St Athan 8.2 h.)

A slight ground frost affected East Anglia and SE England into the 25th before it clouded over here ahead of bands of frontal rain that moved SE'wards across the British Isles during the day. The rain was heavy over high ground of S Scotland, N Wales and N England. N and Cent Scotland had some sunny spells during the day - elsewhere it was generally dull. Showers followed the rain, especially across N Scotland. (Craibstone 13.5C, Okehampton 7.6C maximum, Santon Downham -1.2C minimum, Capel Curig 60.6 mm, Dyce 4.7 h.)

A sequence of (mainly) cold fronts affected the British Isles on the 26th, leading to rain spreading across most areas from the W at some time overnight or during the day. Away from E and N Scotland most places had a mild night. The rain was followed by showers from the W and these turned thundery later over N Ireland and in W Scotland. Temperatures were mainly on the mild side despite a lack of sunshine in many areas. Passengers on a Ryanair flight from Madrid to Dublin were left terrified after the plane was caught in the 70mph winds of Storm Ewan. The Boeing 737 had to abort its landing due to the high winds and was diverted to Shannon, 135 miles away. However, the turbulence was so bad towards the end of the flight, some passengers were reportedly vomiting, with many left severely shaken by the experience. During the morning across Ireland there were reports of flooding as high winds and heavy rain from Storm Ewan battered the country. The storm brought winds of up to 60 mph when it reached landfall and there was flash flooding in Co Clare, Co Galway and in parts of the Irish Midlands. The main Ennis to Ennistymon N85 road was left impassable in several locations for a time, while there was severe flooding along many other parts of the route. Flooding also occurred at the N80 Portlaoise to Carlow road. (Gravesend 14.0C, Dalwhinnie 5.5C maximum, Aboyne -1.0C minimum, Tyndrum 33.8 mm, Shoeburyness 2.8 h.)

The 27th dawned with an air frost in parts of N Ireland and N Scotland and followed a wet night in the SE corner of England. A brisk flow around areas of low pressure to the W and N of the British Isles led to frequent lines of showers that included some heavy hail and isolated. As it turned colder in N Scotland during the day rain turned to snow over high ground. It was generally cloudy in E England, with sunny periods in W England and Wales, but with long spells of sunshine across many areas of E Scotland. (Monks Wood 10.8C, Dalwhinnie 1.7C maximum, Fyvie Castle -1.9C minimum, Wiggonholt 28.0mm, Dyce 9.1h.)

Ground frost was widespread across the British Isles into the 28th with an air frost being notably widespread across much pf inland Scotland and N and Cent Ireland. After a cold start the day remained cold here and in NE England, despite sunny conditions. Showers or rain, and in places snow, affected many areas overnight and throughout the day. Thundery showers were reported at several times of the in the Channel Islands. (Plymouth 10.4C, Leek 3.3C maximum, Dalwhinnie -8.6C minimum, Capel Curig 36.6 mm, Charterhall 8.3 h.)

British Isles weather, March 2017

Parts of Scotland, N Ireland and N England had an air frost on the 1st while cloudier skies further S and in N Scotland led to spells rain; during the day there were showers during the day in W, N and some S areas of Scotland - which fell as snow in parts of the N and on high ground in Scotland, Cumbria and in parts of Ireland. S Ireland, Wales and S and Cent areas of England had a cloudy day with rain at times. (Isles of Scilly 11.3C, Loch Glascarnoch 3.4C maximum, Topcliffe -4.6C minimum, Swyddffynnon 19.0 mm, Kinloss 9.2 h.)

The 2nd dawned after a windy night in S areas of the British Isles, during which rain fell widely across England, Wales and Ireland with some snowfall over higher ground in Wales and N England; wintry weather was also reported in Lincolnshire. Snow and ice disrupted travel in the Peak District and Pennines, and the Snake Pass was closed due to snow for much of the morning. Some rain also fell across N Scotland, with other areas of Scotland having an overnight air frost. During the day precipitation was largely confined to N'wards-moving areas of rain over Ireland, Wales, N England and Scotland (with some snow over the Scottish hills); Ireland was noticeably cloudy while S areas of England had prolonged sunny spells.(Yeovilton 12.2C, Loch Glascarnoch 4.2C maximum, Tyndrum -4.9C minimum, Capel Curig 30.4 mm, Odiham 9.0 h.)

An area of low pressure (centre 980 mb at 2400 GMT) moved into S Ireland later on the 3rd. After an early air frost in N and Cent Scotland, a largely sunny day followed here. Further S the day was largely sunless. Rain overnight in Ireland, Wales and W England later affected all other areas of England, with some heavy rainfall in the evening in parts of Ireland. 27 mm of rain fell in the 24 hours ending 1800 GMT at Cork Airport, while 32 mm fell at Sherkin Island ending at this time. In the evening some thunder was heard in the Channel Islands, Cent S England and in a few places around the London area. (Bude 12.7C, Pateley Bridge Ravens Nest 4.0C maximum, Braemar -4.6C minimum, Middle Wallop 24.8 mm, Kinloss 9.6 h.)

The low pressure system moved slowly N'wards during the 4th towards the Western Isles. As a result, the main rain area continued to move slowly N'wards across Scotland (with some snow over high ground) , while it turned drier and a little brighter in the S Scotland later. After widespread overnight rain much of Cent and E England were drier during the day with some sunshine, especially in Cent S England and the Midlands. Much of Ireland and parts of Wales and W England had showery conditions during the day. (Northolt 13.0C, Dalwhinnie 1.4C maximum, Altnaharra -1.7C minimum, Craibstone 31.2 mm, Waddington 6.6 h.)

Pressure remained low across Scotland on the 5th with a cloudy day with rainfall resulting in the N. Further S, there were showery spells in N England, N Ireland and S Scotland - N Ireland and S Scotland seeing the best of the sunshine. Rainfall overnight across Ireland W parts of England moved NE'wards - with most of Wales, and S and Cent parts of Ireland and England having falls during the day. Some snow fell over high ground in parts of N England while hail and thunder were reported on Jersey in the morning. (Gravesend 11.5C, Lake Vyrnwy 3.2C maximum, Lentran -2.4C minimum, Capel Curig 22.6 mm, Magilligan 9.3 h.)

Widespread frontal cloud on the 6th gradually moved NE'wards during the day. However, a few breaks overnight allowed an air frost to form in a few parts of Scotland, Wales and N Ireland, while during the day these breaks led to some sunshine as a weak ridge of high pressure developed from the W later. Showers fell in places being heavy around East Anglia later in the day, while frontal rain moved across Wales and into N areas of England into the evening. (St James Park 11.6C, Thomastown 5.4C maximum, Altnaharra -3.8C minimum, Guernsey Airport 26.0 mm, Morecambe 9.4 h.)

Weak frontal rain cleared E areas of the UK early on the 7th with a slight air frost following under a weak ridge of high pressure. However, further rain areas soon spread from the SW (some of it associated with a developing frontal low that was located over the Isle of Man (1003 mb) at 2400 GMT). This rain had affected all areas by the evening, by which time much of England and Wales lay under a warm sector. Ahead of the rain much of E England had a sunny day. (Gravesend 12.1C, Lerwick 5.3C maximum, Braemar -5.5C minimum, Camborne 10.2 mm, Leconfield 8.6 h.)

There was widespread rainfall overnight into the 8th, while during the day rainfall was largely confined to S parts of England, Wales and Ireland, along with N and W Scotland. Scotland had windy and showery day, with some thunder. Heavy rain in W Scotland in the evening (associated with a low system to the W of Scotland at 2400 GMT) turned to snow over the mountains. Away from the rain in S areas, many other places had sunny spells, although it turned misty with some fog across the S half of England and Wales in the evening - following a mild day in SE England. (Northolt 15.1C, Loch Glascarnoch 5.9C maximum, Aboyne -0.7C minimum, Cluanie Inn 33.8 mm, Magilligan 8.2 h.)

Overnight into the 9th, rain fell across S England and much of Scotland. A mainly dry day followed, although the rain persisted across parts of N Scotland into the afternoon and a warm front gave some rain, mist and fog across the Channel Isles, Cornwall and parts of S Ireland. As this front edged N'wards there was rain in Cent and N Ireland in the evening. It was a mild day in Cent S and SE England. (St James Park 17.5C, Dalwhinnie 7.6C maximum, Aboyne 0.1C minimum, Achnagart 13.0 mm, Sheffield 10.6 h.)

S England remained rather misty on the 10th, with fog in places at times, especially in SW England. Parts of E and Cent Scotland had an early air frost before light rain and drizzle spread NE'wards from Ireland across much of Scotland during the morning. Rain and drizzle also affected parts of N England; indeed, except around the Thames Estuary it was a generally dull day in most parts of the British Isles despite relatively high surface pressure. (Chivenor 16.5C, Strathallan 6.2C maximum, Aboyne -2.8C minimum, Stornoway 6.0 mm, Manston 7.2 h.)

Overnight into the 11th rain affected mainly Ireland, N and W Scotland; much of England dawned misty with a few fog patches. During the day the main rain areas were across Scotland, N Wales and N England with lesser falls further S into S Wales and the Midlands. It remained misty with coastal fog in SW England during the day and away from the fog it was a warm day - despite the rather cloudy skies. The best of the sunshine was to be found in SW Ireland after the early rain cleared. (Gravesend and St James's Park 17.7C, Dundrennan 7.9C maximum, Aboyne 4.0C minimum, Lusa 8.2 mm, Shannon Airport 8.2 h.)

Fronts crossed E'wards over the British Isles on the 12th, pushing bands of rain across most areas. The sunniest areas were consequently across Ireland and SW England - following a rather misty start to the day in all areas of the British Isles. In places fog was persistent for much of the day. (Fyvie Castle 16.4C, Lerwick 7.7C maximum, Kinbrace -0.9C minimum, Lyneham 6.6 mm, Shannon Airport 9.2 h.)

After a widespread ground frost across the British Isles on the 13th, a warm day followed in most areas. Many places had a sunny day, although cloudier skies were the norm across many parts of Scotland and rather misty conditions prevailed for large parts of the day in some W areas of Ireland and Scotland, and over SW England. Rainfall was largely confined to NW Scotland overnight, with only very slight falls anywhere during the day. (Murlough 16.6C, Lerwick 9.0C maximum, Katesbridge -1.6C minimum, Lusa 7.8 mm, Odiham 10.2 h.)

The 14th dawned after a mainly mild night, especially in parts of Ireland where minimum temperatures overnight remained above 10C. Across S Ireland, Wales and England a mild day followed, although it was rather cloudy in much of S England. Rainfall overnight was largely confined to W Ireland, W and N Scotland - with further falls across Scotland during the day. Elsewhere it was mostly dry, although there was some drizzle and fog over SW England. Mist was widespread around dawn over Cent and S England and in W Ireland - while over the Northern Isles there was hail and thunder along with gale force winds gusting over 60 mph. Some power cuts occurred on the Isle of Lewis during the day, and windy conditins caused a high-sided vehicle to blow over on the Forth Road Bridge in the afternoon. (Hawarden 17.0C, Dalwhinnie 7.7C maximum, Shoreham 1.4C minimum, Achnagart 32.8 mm, Charterhall 9.1 h.)

The 15th dawned with widespread mist and fog, thick in places, across England, Wales and Ireland - and with rainfall across N and NW Scotland. Pressure was high across S areas - resulting in the fog and mist reforming again in the evening in many S areas of England in the evening. Fog caused travel chaos for airline passengers at London City Airport in the morning, leaving more than 60 flights to and from Europe disrupted. Further rain fell during the day over N Scotland, while in the evening an advancing warm sector spread rain and drizzle from the W across Ireland. It was a very sunny day across parts of E Wales and the Midlands. (Kew Gardens 18.8C, Lerwick 7.9C maximum, Aboyne -0.4C minimum, Kinlochewe 7.0 mm, Lake Vyrnwy 11.0 h.)

The 16th was a rather cloudy day, except in parts of the SE corner of England. This was the result of a pair off cold fronts that brought rain and drizzle across most areas during the day from the NW; in parts of W Scotland and over high ground the rain fell as snow. Patchy fog across many parts of England cleared by mid-morning, although some mist persisted until midday in parts of S England. The rain weakened as it spread SE'wards. (Gravesend, Shoeburyness 17.1C, Resallach 7.5C maximum, Santon Downham -0.3C minimum, Achnagart 16.4 mm, Shoeburyness 10.5 h.)

A brisk W'ly flow on the 17th drew fronts across many areas during the day, leading to outbreaks of rainfall that occurred widely across Ireland, Scotland, Wales and W England by the evening. Falls further E in England tended to be slight in nature. It was a generally dull day, except at first in S England and also over the Northern Isles. As the day developed a tightening N-S pressure gradient led to blustery conditions. (Murlough 12.2C, Loch Glascarnoch 3.4C maximum, South Newington -0.6C minimum, Stonyhurst 47.4 mm, Jersey Airport 7.6 h.)

A brisk W'ly flow on the 18th led to a rather cloudy day with rain and drizzle across the British Isles. There was some air frost across N Scotland at first, while the majority of the pre-dawn rainfall was confined to places W of a line Durham-Exeter. Rain also fell further E during the day, but amounts here were mainly slight; NE and N Scotland was the brightest area of the British Isles. With a warm sector across all but N and Cent Scotland by 2400 GMT there was fog over some hills and coastal areas in SW parts of the UK and in S Ireland. (Pershore 16.1C, Baltasound 4.9C maximum, Loch Glascarnoch -4.0C minimum, Capel Curig 26.2 mm, Lerwick 7.7 h.)

The warm sector moved away to the SE during the 19th after giving some overnight minimum temperatures of 11-12C in SE England. There was rain overnight over Scotland and N Ireland and this was followed by showers from the NW. S parts of England, Wales and Ireland began with misty conditions in places and a rather cloudy day followed as the rain and drizzle, although weakening, moved SE'wards. The day was another blustery one. (Santon Downham 16.8C, Loch Glascarnoch 7.0C maximum, Kinbrace 2.7C minimum, Eskdalemuir 32.0 mm, Leeming 7.2 h.)

An area of low pressure moved from off NW Ireland across the Shetlands on the 20th. This spread frontal rain to most areas during the day, following some light falls overnight in S areas. S England remained rather cloudy but brighter conditions spread S'wards to most other areas. Showers in these clearer areas consisted of hail and thunder in places with some snow in parts of W Scotland and N Ireland. (Writtle 14.2C, Dalwhinnie 5.2C maximum, Aboyne -0.2C minimum, Sennybridge 27.6 mm, Kinloss 9.1 h.)

Wintry falls were widespread on the 21st over areas of N and Cent Scotland, N and W Ireland and N England. The M8 was closed westbound by a jack-knifed lorry as a result of snowy conditions and the M77 was also partially blocked for a time, as were some other high-level routes such as the A83 at the Rest and Be Thankful. A few showers in Scotland were accompanied by hail and thunder. Parts of Cent Scotland and N Ireland had a slight air frost; mush of E and SE England was sunny with occasional showers which died out later in the day. However, as a low centre moved across S Ireland into the S parts of the Irish Sea, associated fronts pushed some heavier from with thunder from SW England towards N England later in the day. (Heathrow 12.6C, Dalwhinnie 1.8C maximum, Killylane -1.6C minimum, Cluanie Inn 27.0 mm, Morpeth Cockle Park 10.6 h.)

Inland areas of Scotland and N Ireland had a widespread air frost on the 22nd - in a N'ly flow that resulted partially from a low centre that remained over or closer to SW Britain during the day. There was rain overnight across S Ireland, Wales, SW and N England. N Scotland had wintry showers during the day, as did many areas of Ireland. These wintry showers also affected parts of N England and N Wales. Rain cleared NE'wards from Wales, Cent and S England during the afternoon - the sunniest areas were consequently across W parts of Ireland and Scotland. Mist and fog formed across many parts of N England and the Midlands into the evening. Many roads in Cumbria were affected by snow including the Kirkstone Pass. (Northolt 11.9C, Eskdalemuir 3.1C maximum, Dalwhinnie -8.6C minimum, Blencathra 40.0 mm, Tiree 11.1 h.)

Parts of N and Cent Scotland, and areas in or close to Wales and SW England, had an air frost on the 23rd. Further E in England there was overnight rain that then spread E on an E'ly flow located to the S of high pressure. This rain eventually cleared away to the SW over SW England. Sunny skies followed this rain across much of England and Wales and it was also a generally sunny day across the N half of Scotland. S Scotland and N Ireland remained generally dull. (Porthmadog 13.5C, Carterhouse 5.5C maximum, Kinbrace -7.3C minimum, Chillingham Barns 24.6 mm, Kirkwall 11.2 h.)

There was a widespread ground frost over Scotland, N England and in N and Cent Ireland into the 24th - with air frost across Scotland in particular. High pressure remained centred over S Scotland N England during the day (centre 1036 mb over NE England at 2400 GMT). As a result rainfall amounts were slight - mainly occurring over SW England and the Channel Islands during the morning, with some drizzle across the Northern Isles during the day. Away from these wet areas many places had a sunny day, with 10-11 h of sunshine in many areas. 19 mm of rain fell at Guernsey Airport in the 12 hours ending 0600 GMT. (Porthmadog 16.0C, Okehampton 6.9C maximum, Tyndrum -4.4C minimum, Isle of Portland 4.0 mm, Leconfield 11.4 h.)

High pressure persisted, and was slow-moving, on the 25th. Many inland areas away from the Northern Isles had a ground frost, with an air frost across much of Scotland, N and Cent Ireland, N England and Wales. Some mist and fog formed by dawn over Cent and E England - while away from the Northern Isle sit was a largely dry day with 10-12 h of sunshine in most places. It was a warm day in many areas as a result. (Aboyne 19.1C, Fair Isle 8.3C maximum, Katesbridge -5.4C minimum, Lerwick 2.4 mm, Charterhall 12.2 h.)

High pressure again dominated the weather on the 26th. Some light rain and drizzle again affected the Shetlands. Elsewhere it was warm, dry and sunny after an early air frost in parts of Scotland, N England, N Wales and N Ireland. 10-11 h of sunshine occurred widely over the British Isles, despite some mist at times, early and late, in E England. In the evening frontal rain spread from the S into SW Ireland. (Aviemore 19.9C, Fair Isle 8.0C maximum, Magilligan -4.1C minimum, Lerwick 1.2 mm, Kirkwall 12.0 h.)

The 27th dawned with a mist, and some fog, in many E areas of the UK and in N Scotland. Parts of E Scotland also had a slight sir frost. A S'ly flow developed during the day - which remained rather misty or hazy in many areas. In places this poor visibility also produced some slight drizzle. Despite this, many places again had a sunny day although parts of E England and E Wales, along with Shetland, remained rather dull. Where the sun was prolonged it was, again, a warm day. (Aviemore 19.1C, Lake Vyrnwy 5.5C maximum, Altnaharra -3.2C minimum, Goudhurst 0.2 mm, Rostherne No 2 11.8 h. )

Haze, mist and fog was widespread by dawn on the 28th across all but the W half of Scotland. In places this led to some slight drizzle overnight, while more general rain affected SW Ireland early in the morning. The fog led to dozens of flights being cancelled out of London airports; the fog also led to the Woolwich Ferry service being suspended, as were the Thames Clippers at Royal Arsenal Woolwich. Showery outbreaks moved NE'wards during the day with some thunder later in parts of the N Midlands, Norfolk and Lincolnshire. Much of Scotland remained dry but misty - apart from some light falls in N areas. The S half of England had a warm day, especially around the London area although the nest of the sunshine tended to be in parts of Cent Scotland away from the coasts. (Gravesend 19.1C, Inverbervie 5.8C maximum, Braemar -2.6C minimum, St Athan 9.0 mm, Kinloss 10.6 h.)

Widespread fronts gave a cloudy day on the 29th. After a largely dry night across Scotland, overnight rain further S spread N here during the day. It was a generally mild day due to the S'ly flow, but it was misty or foggy in some coastal areas during the day. During the day SE England turned largely dry and many other E areas of England were also generally dry. (Cranwell 17.0C, Fair Isle 6.7C maximum, Balmoral 2.1C, Whitechurch 30.4 mm, Stornoway 3.7 h.)

A warm sector led to a mild night across much of England with overnight minimum temperatures of 10-12C in many places here on the 30th. Although it turned unusually warm here during the day with 20C reported as far N as Lincolnshire, frontal cloud led to widespread rain in W areas of the British Isles. Showery outbreaks over parts of England and Wales in the evening.(Gravesend 22.1C, Fair Isle 8.5C maximum, Resallach 2.1C minimum, Capel Curig 46.0 mm, Herstmonceux 9.8 h.)

Frontal rain crossed much of the UK from the W overnight and into the morning of the 31st, with the rain then giving way to showers from the W. More rain followed over S Ireland, SW England and Wales later in the afternoon and evening. It was another mild day in Cent and E areas of England after overnight minimum temperatrures of 10-12C in places here. (Hull East Park 18.9C, Lerwick 8.5C maximum, Baltasound 2.9C minimum, Harris Quidnish 32.8 mm, Jersey Airport 7.9 h.)

British Isles weather, April 2017

Fronts associated with an area of low pressure to the N of Scotland on the 1st led to rainfall overnight over Ireland and W areas of Britain. During the day the rain became more showery and widespread, with some thunder in NE England in the afternoon. Between the showers most places had sunny intervals and many places in the S half of England reached 15-16C. (Gravesend 17.6C, Fair Isle 9.7C maximum, Fyvie Castle 0.6C minimum, Lake Vyrnwy 22.4 mm, Jersey Airport 9.3 h.)

A ridge of high pressure developing from the SW during the 2nd led to a mainly dry day. Many areas, away from N Scotland, had a slight inland ground frost at first, while a weak front led to some light, patchy, rain across parts of Ireland and England. Many places from E Scotland, S'wards, reported in excess of 10 h of bright sunshine during the day. (St James Park 17.2C, Fair Isle 8.8C maximum, Katesbridge -1.9C minimum, Loch Glascarnoch 3.2 mm, Leuchars 12.0 h.)

High pressure led to a widespread ground frost on the 3rd in E Scotland and across much on inland England. It was mild overnight in W Ireland (overnight minimum temperatures close to 10C) ahead of fronts that brought rain here by dawn. E ad S England had fog patches before dawn before the rain in the W pushed E'wards over Scotland, Ireland, Wales and w England during the day and into the evening. Ireland and W Scotland had a rather cloudy day, but some places in E England recorded over 10 h of sunshine. (Cambridge NIAB 17.9C, Dundrennan 8.7C maximum, Upper Lambourn -1.5C minimum, Cluanie Inn 18.8 mm, Sheffield 11.6 h.)

Fronts crossed the British Isles from the W during the 4th and by midnight pressure had risen from the W, to 1036 mb over SW Ireland. Light rain crossed the UK overnight, mainly in S areas. However, there was some rain overnight across Scotland - which then continued to affect N Scotland during the day. SE Scotland. N England and N Wales had a sunny day - but it was rather dull in Cent S and SE England, and also in East Anglia. The rain across N Scotland was associated with a depression further N, which gave gusts over 60 mph on the Northern Isles. (Cavendish 17.3C, Dalwhinnie 7.4C maximum, Balmoral 2.5C minimum, Resallach 7.8 mm, Charterhall 11.1 h.)

High pressure dominated the weather on the 5th, centred close to SW Ireland. Many parts of England and Wales had a ground frost at first while a weak front gave spells of rain across N and W Scotland and also N Ireland overnight. This light rain gradually faded during the day but much of Scotland and Ireland, along with NW England and N Wales, had a cloudy day. Cent S and SE England had a very sunny day. (Cardiff Bute Park 16.6C, Fair Isle 7.7C maximum, Sennybridge -1.1C minimum, Resallach 2.4 mm, Hurn 11.8 h.)

High pressure persisted close to S Ireland on the 6th leading to some mist around dawn in parts of Cent and E England. Ground frost was widespread over England, Wales and E Scotland, along with a slight air frost in a few places. There was light rain at times in N and W Scotland. W areas of the British Isles remained rather cloudy although it was a sunny day across much of England and in parts of E Scotland. (St James Park 18.5C, Blencathra 8.2C maximum, Kielder Castle -1.9C minimum, Baltasound 7.2 mm, Exeter Airport 12.5 h.)

During the 7th the anticyclone centred moved E'wards across S England. Mist and fog patches formed before dawn over S and E England - with much of England having an overnight ground frost. W and N Scotland had some light rain and drizzle overnight and during the day - which again turned sunny over much of Wales and S England. Elsewhere the day was rather cloudy, while mist formed in the evening over much of England and Ireland. (Wisley 18.8C, Spadeadam 8.7C maximum, Trawscoed -1.8C minimum, Lerwick 3.4 mm, Camborne and Jersey Airport 12.6 h.)

A warm S'ly flow invaded the British Isles on the 8th. There were widespread mist and fog patches in S Scotland S'wards before dawn along with a widespread ground frost here also. N and NW Scotland had some slight rain and drizzle at times and it was rather cloudy here. Elsewhere it was a sunny day - and a very warm one over England and Wales. (Hampton Water Works 21.4C, Fair Isle 9.8C maximum, Shap -3.4C minimum, Lerwick 0.4 mm, Charterhall 12.8 h.)

A weakening band of rain crossed Scotland, Northern and N England on the 9th, introducing cooler air in its wake. Elsewhere, after a misty/foggy start with a ground frost in places, the day was dry and warm (unusually warm in some E areas) - before cloud spread from the N later. Much of S England and East Anglia again had a very sunny day. (Cambridge NIAB 25.5C, Fair Isle 9.0C maximum, Eskdalemuir -1.2C minimum, Resallach 11.0 mm, Shoeburyness 12.6 h.)

A NW'ly flow on the 10th gave some showers in Scotland, with more persistent rain later in the W and N. Most of S Ireland, England and Wales remained dry and there were sunny spells in all areas - especially in S England and the Channel Islands. Behind the cold front that cleared S England in the morning it was much cooler than in previous days. (Herstmonceux 15.9C, Lerwick 5.7C maximum, Katesbridge -1.1C minimum, Cluanie Inn 12.8 mm, Jersey Airport 11.4h.)

High pressure again dominated in the S on the 11th, but across the N half of the British Isles a W'ly flow brought spells of rain and drizzle, especially across N Scotland. After a ground frost in many parts of England and Wales, it was a sunny day over Wales and the S half of England - but cloudier elsewhere. (Heathrow 16.7C, Fair Isle 8.6C maximum, Baltasound -1.6C minimum, Resallach 73.0 mm, St Athan 12.5 h.)

A cold front spread S'wards across most areas on the 12th although associated rainfall amounts decreased during the day. A showery flow from the NW followed the front - the showers interspersed with sunny intervals. It was also sunny at first in the S, ahead of the front. (St James Park 17.6C, Cluanie Inn 7.2C maximum, Shoreham 2.0C minimum, Cluanie Inn 21.2 mm, Tiree 9.2 h.)

The 13th was a rather cloudy day, particularly in areas of W Ireland and E Wales. Parts of S England were misty before dawn, while much of Scotland and N Ireland had some light falls of rain and drizzle at times, both overnight and during the day. (Heathrow 15.4C, Lerwick 7.6C maximum, Benson -0.2C minimum, Kinlochewe 8.0 mm, Guernsey Airport 8.2 h.)

The presence of fronts on the 14th made for a rather cloudy day. Early rain over Ireland and Scotland soon spread E'wards, although much of S England initially had a slight ground frost. It remained dry in the extreme SE corner of England until late evening, and temperatures generally fell in the N and W once the frontal rain had cleared and showery conditions developed. (Pershore College 16.1C, Altnahinch Filters 7.8C maximum, Baltasound -0.3C minimum, Capel Curig 15.6 mm, Guernsey Airport 7.7 h.)

Parts of N Ireland and Cent Scotland had a slight ground frost in the cooler air across N and W areas on the 15th. Overnight rainfall was widespread, but during the day was mostly confined to Scotland and Ireland due to the presence of some weak fronts here - but with sunny spells in all areas. (Heathrow 15.7C, Dalwhinnie 7.6C maximum, Aboyne -1.5C minimum, Resallach 14.8 mm, Charterhall 11.4 h.)

Overnight into the 16th there was widespread, but mostly light, rain over Scotland and Ireland - and this then spread to all areas during the day. The result was a generally cloudy day, especially over W Ireland. Some of the showers were of hail over Scotland, and were locally wintry in N Scotland. (Hurn 16.1C, Spadeadam 5.3C maximum, Altnaharra -0.3C minimum, Leconfield 11.0 mm, Guernsey Airport 12.5 h.)

Parts of N and E Scotland had an air frost on the 17th in a weak N'ly flow. There was slight overnight rain in Ireland, Wales and England - which continued on and off here in places during the day. Showers, wintry in the N, moved SE'wards across Scotland into N and E England by evening. It turned sunnier Scotland and N Ireland, but remained rather duller elsewhere, except over East Anglia. (Cardiff Bute Park 15.6C, Fair Isle 5.9C maximum, Kinbrace -4.8C minimum, Fair Isle 7.4 mm, Tiree 12.4 h.)

High pressure on the 18th led to a widespread ground early in the day, with air frost being widespread inland across Scotland and N England. There were showers and rain early in the morning in E England, and in W Scotland and Ireland later in the day. Much of England had a sunny day but it was rather cloudy elsewhere, especially in W parts of the British Isles. (Hampton Water Works 14.1C, Dalwhinnie 7.6C maximum, Dalwhinnie -5.9C minimum, Manston 3.4 mm, Hurn 12.4 h.)

Frontal cloud spread W during the 19th, after a widespread ground frost over England and Wales and a slight air frost in some E areas of England. Rainfall amounts were generally slight from this cloud - with very little rain in E areas. Parts of E Scotland turned warm in a foehn wind. (Aboyne 16.6C, St Bees Head 8.7C maximum, Santon Downham -4.0C minimum, Killylane 4.0 mm, Guernsey Airport 13.5 h.)

S England had a widespread ground frost on the 20th while there was patchy rain further N over England overnight. High pressure (centred 1038 mb near Valentia at 0000 GMT) meant that rainfall amounts during the day were mainly slight - although away from E Scotland and areas of SW England, W Ireland and the Channel Islands it was rather dull. E Scotland, and parts of NE England, were warm for the time of year. (Inverbervie 18.7C, Fair Isle 9.3C maximum, Goudhurst -2.3C minimum, Cassley 5.4 mm, Guernsey Airport 12.9 h.)

The 21st was a cloudy day across England, Wales and much of Ireland - with mist and some fog patches in S England, W Scotland and in parts of Ireland before dawn. A slow-moving cold front pushed light rain SE'wards from Scotland to N England and N Wales during the day - with brighter skies once the rain cleared. It was locally warm over NE England. (Bridlington 17.9C, Baltasound 6.9C maximum, Topcliffe 1.0C minimum, Cluanie Inn 24.6 mm, Guernsey Airport 13.2 h.)

It was cool in the N on the 22nd behind a weak cold front, that gradually moved S'wards over S England later in the day. Parts of Scotland had a slight ground frost at first and a cool day followed here, and in N Ireland, with some light showers. It was sunnier and warmer further W and S. (Usk No.2 17.6C, Lerwick 4.2C maximum, Shap -1.8C minimum, Glenanne 7.2 mm, Morecambe 13.3 h.)

High pressure soon gave way on the 23rd to bands of frontal rain over N areas. There was an air frost at first over parts of N England and surrounding areas, and in parts of N Ireland. Much of the country was then sunny and it turned warm in some SE areas. Heavy snow fell for a time on Shetland in the late afternoon and early evening near a depression centre that crossed the Northern Isles from the W during the day. (Wisley 17.3C, Baltasound 6.0C maximum, Shap -3.5C minimum, Lerwick 17.0 mm, Guernsey Airport 13.5 h.)

Much of England and Wales was cloudy on the 24th with some light, but patchy rain falling from a cold front. Cooler conditions further N led to showers with some hail and snow, the latter as far S as N England. Across Scotland snowfall was more prolonged over higher ground. (Hurn 16.5C, Cluanie Inn 3.3C maximum, Benson -0.3C minimum, Cluanie Inn 19.2 mm, Prestwick 10.3 h.)

On the 25th there was a widespread frost at first (for some places in S England the first air frost for about two months) as a result of a cool N'ly flow to the east of a large anticyclone to the W of Ireland. Wintry showers over Scotland moved S'wards during the day reaching parts of the Midlands. Thunder accompanied the showers over parts of England and Wales away from the SE. (Cardiff Bute Park 12.4C, Balmoral 3.4C maximum, Redesdale Camp -4.1C minimum, Aboyne 18.6 mm, Manston and Ronaldsway 12.6 h.)

A N'ly flow persisted in all areas on the 26th. Many places had another air frost which was unseasonably sharp in parts of Wales. Showers, wintry in places, continued near many coasts. The showers became widespread during the day, especially over Cent and E England; they fell as hail, and locally snow, and there was some thunder in the afternoon in parts of East Anglia and the London area. More general frontal rain affected N Scotland later in the day. (Killowen 13.6C, Balmoral 6.1C maximum, Sennybridge -4.8C minimum, Scarborough 10.6 mm, Bude 13.3 h.)

Air frost was widespread over England, especially in the S and the Midlands on the 27th - with an unseasonably sharp frost in places. Away from the Channel Islands cloud and spells of light rain or drizzle moved SE'wards. It was generally cold, and locally very cold, but was milder and brighter for a time over parts of S Scotland and N England. This milder weather was followed by some heavy rain here later in the day. (Edinburgh Botanic Gardens 14.8C, Lake Vyrnwy 7.7C maximum, Sennybridge -5.6C minimum, Kinlochewe 16.6 mm, Guernsey Airport 10.6 h.)

The 28th was mostly cloudy with some light rain due to a slow-moving, and weakening front located along the spine of the UK. Another area of frontal rain affected W Ireland into the evening. (Wisley 15.6C, Inverbervie 8.0C maximum, Aboyne -2.7C minimum, Resallach 7.6 mm, Lerwick 11.4 h.)

Away from the Channel Islands and the extreme SE corner of England the 29th was a rather cloudy day - particularly across much of E Scotland and N England. Some light rain fell in W and NW areas - but it turned warm in the sunnier parts of SE England. (Gravesend 16.8C, Fair Isle 7.5C maximum, Drumnadrochit -1.5C minimum, Capel Curig 3.2 mm, Herstmonceux 10.5 h.)

Low pressure close to SW Ireland drew a warm flow from the SE across the British Isles on the 30th, leading to a warm day in many areas. However, fronts from the low pushed rain and drizzle into Ireland, Wales and SW England as the SE'ly flow strengthened in SW areas. It was chilly in the SW areas, and also near NE-facing coasts as the wind picked up. (Gravesend 18.4C, Fair Isle 8.0C maximum, Pateley Bridge Ravens Nest 3.5C minimum, Plymouth 23.6 mm, Leconfield 9.5 h.)

British Isles weather, May 2017

Low pressure affected S areas of the British Isles on the 1st. As a result it was cool with rain and then showers across much of England and Wales, although there was some sunshine here later. Much of Ireland had a misty start to the day, as did parts of E Scotland; it remained dull in E Scotland but turned sunny elsewhere there. Parts of SW Scotland and N Ireland turned warm during the afternoon. (West Freugh 20.6C, Craibstone 8.5C maximum, Aboyne 3.1C minimum, Dunkeswell Aerodrome 33.2 mm, Kinloss 13.1 h.)

Many areas of the British Isles had a misty start to the 2nd, with some fog in parts of E England, the Midlands and N England. High pressure developed from the N during the day leading to a mainly dry day everywhere. However, some warm conditions in S Britain led to a band of rain and showers in Se England later. It was a generally sunny day, especially over Ireland and w areas of the UK. (Achnagart 21.0C, Loftus 9.1C maximum, Tain Range -1.6C minimum, Frittenden 5.0 mm, Lerwick 14.8 h.)

High pressure on the 3rd brought a mainly E'ly flow across the British Isles. There was a misty start to the day over Ireland and E Scotland with parts of N England and cent Scotland having a slight air frost. Frontal cloud gave some light rain in parts of East Anglia and SE England; elsewhere, it was a mainly sunny day - particularly over Scotland, Ireland and W Wales. It was quite warm in W parts of Scotland and Ireland - but much cooler in the rain area in SE England. (Achnagart 20.2C, Wych Cross 9.2C maximum, Aviemore -2.4C minimum, Manston 4.4 mm, Aberdaron 14.0 h.)

Continuing high pressure on the 4th (MSL pressure around 1038 mb on Shetland at 1200 GMT) led to another mainly dry and sunny day. Parts of Cent Scotland had a slight air frost and there was some light rain overnight in S England. After a hazy start across S and Cent S England, some places again recorded over 12 h of sunshine - although it was rather dull in East Anglia, Cent S and SE England. (Porthmadog 19.5C, Fair Isle 9.1C maximum, Braemar -4.4C minimum, East Malling 0.6 mm, Stornoway 14.9 h.)

The 5th was another dry, anticyclonic day - although as the pressure gradient increased in SW Engand and S Ireland later in the day there were gusts to 60 mph in SW England and some light rain in the evening in parts of Cornwall and in the Channel Islands. Under high pressure parts of Cent Scotland and N England had an air frost at first - but then away from S England, S Ireland and East Anglia it was a very sunny day. (Kinlochewe 19.7C, Fair Isle 10.0C maximum, Kinbrace -4.7C minimum, Wych Cross 0.2 mm, Tiree 15.0 h .)

Inland areas of Scotland, and parts of N England, had an air frost on the 6th. Scotland and the N half of Ireland then had a sunny day. Elsewhere it was rather cloudy with Cornwall and the Channel Islands having a wet day. There was also some rain and drizzle over the N Midlands and in parts of East Anglia - with misty conditions forming in SW England and the Channel Islands in the evening. Scotland and N Ireland became warm in places away from the E-facing coasts. (Tyndrum 20.4C, Pennerley 8.2C maximum, Braemar -5.0C minimum, Isles of Scilly 23.6 mm, Tiree 14.0 h.)

Many places in E Ireland, inland Scotland and NW England had a ground frost into the 7th. S'ward-moving fronts gave spells of light rain and drizzle at times overnight and during the day in E areas of England and Scotland. Many S and W areas had a warm and sunny day, as did SW areas of Scotland and much of the N half of Ireland. (Pershore 21.3C, Loftus 8.1C maximum, Shap -1.8C minimum, Kinloss 1.4 mm, Tiree 15.0 h.)

High pressure on the 8th led to a mainly E'ly flow during the day - and to cool conditions in E parts of the UK as a result. The day was, however, generally dry apart from a few very light falls of rain in the E areas. It was rather dull close to the E coast of England and Scotland and in much of E England. Elsewhere, it was sunny - and warm in places. (Castlederg 19.5C, Fylingdales 7.4C maximum, Shawbury -0.7C minimum, Isles of Scilly 0.2 mm, Tiree 15.1 h.)

Weakening high pressure was centred over the British Isles during the 9th. Much of Ireland and many W areas of the UK had a ground frost and air temperatures dropped below -3C in parts of Cumbria and cent Scotland. Many E-wards facing coastal areas had a cool day while W areas were warmer with long spells of sunshine. Some rain and drizzle affected Shetland during the afternoon and evening. (Castlederg 18.5C, Lerwick 6.9C maximum, Shap -5.1C minimum, Baltasound 2.4 mm, Prestwick 14.7 h.)

Light winds on the 10th led to a widespread ground frost with an air frost in places as far S as SE England. By dawn there was widespread mist, and some fog, across Ireland, Wales and England with cloudier conditions further N leading to overnight in the Northern Isles. Most of N Scotland then had a cloudy day with some patchy rain in the N. Elsewhere the day was sunny and it turned warm in places away from the coasts. (Sheffield 19.8C, Lerwick 6.9C maximum, Braemar -3.8C minimum, Kirkwall 6.4 mm, Wattisham 14.5 h.)

Ground frost was widespread on the 11th away from S England and N Scotland - and many areas away from N and W Scotland had a misty start to the day. Places from S Scotland to the N Midlands, and also areas of Ireland, had a sunny day and it became quite warm. It was cloudier in S England in particular - and warm in places here too; showers developed with extensive thundery activity during the afternoon and evening over areas bordering the Bristol Channel. There was also thunder over some other parts of S Britain. (Porthmadog 22.9C, Fair Isle 7.9C maximum, Drumnadrochit -1.8C minimum, Usk No.2 17.8 mm, Leeming 13.8 h.)

Rainfall was widespread on the 12th as an area of low pressure became centred over E Ireland (995 mb) by 2400 GMT. Overnight it was cloudy with rain at times across Ireland, Wales and S and Cent areas of England with temperatures generally above 10C here. W Scotland and N England along with the areas that were wet overnight saw rainfall during the day. Elsewhere in Scotland it was bright and quite warm in places - but there was rain in E Scotland by midnight. (Drumnadrochit 21.9C, Inverbervie 9.7C maximum, Braemar -2.0C minimum, Isles of Scilly 25.8 mm, Kinloss 11.9 h.)

Most places had some rainfall during the 13th, with falls being most persistent across Ireland and W Scotland. Cloudy skies meant a mild night and in the 12 hours ending 0600 GMT 21 mm of rain fell at Finner. Away from Scotland and Ireland rainfall totals were mainly small during the day - and with sunny spells across England and wales it turned warm in parts of E England. (Weybourne 19.9C, Lerwick 8.6C maximum, Shap 6.5C minimum, Lough Fea 18.0 mm, Aberporth 7.8 h.)

Frontal rain spread across the British Isle overnight into the 14th, clearing England by midday and NE Scotland by late afternoon. Sunny spells followed in most areas, along with some showers before it turned cloudy in the afternoon and evening in S Ireland, SW England and the Channel Islands - with further rain in these areas by midnight. It was again quite warm in some E areas. (Heathrow 20.9C, Fair Isle 11.1C maximum, Derrylin Cornahoule 4.9C minimum, Upper Lambourn 16.6 mm, Guernsey Airport 13.7 h.)

The frontal rain across Ireland and SW England at first on the 15th spread to all areas during the day - giving spells of rain throughout the day following a mild night in W areas. 23 mm of rain fell in the 12 hours ending 0600 GMT at Valentia with heavier falls during the day over high ground in Wales. It was warm in some of the drier parts of NE Scotland where the rain was late to arrive - and by midnight there was a long S'ly surface fetch of wind in E parts of the UK. (Lossiemouth 20.1C, Fair Isle 9.8C maximum, Aboyne 1.5C minimum, Capel Curig 46.4 mm, Aviemore 4.0 h.)

East Anglia and SE England remained in this S'ly fetch on the 16th - and it was a warm day here as a result. It was a mild night in all areas - minimum temperatures remained above 14C in many inland areas of the British Isles before rising to 23C and above in this SE corner. Elsewhere, most areas had spells of SE'ward moving spells of rain to a greater or lesser extent - but across the Orkneys and S Ireland it was a sunny day. Overnight (12 hours ending 0600 GMT) minimum temperatures included 15.8C at Kinloss and Hawarden. (Gravesend 25.8C, St Bees Head 12.7C maximum, Lerwick 8.4C minimum, Capel Curig 38.6 mm, Kirkwall 12.5 h.)

Parts of Cent Scotland had an air frost into the 17th, while overnight minimum temperatures in Cent S and SE England were around 14-15C in places. Areas of rainfall across England and Wales were slow-moving during the day and only cleared E England very late in the evening. After a dry start in the W, rain spread across Ireland and W Scotland later in the day, becoming patchy. It was warm in the extreme SE of England ahead of the rain - and sunny following the rain across much of Scotland, Ireland (and later Wales). (Langdon Bay 25.0C, Okehampton 9.3C maximum, Braemar -1.9C minimum, Holbeach 40.4 mm, Lerwick 14.1 h.)

It turned misty with some fog in the Midlands and East Anglia into the 18th. Sheltered areas as far S as SE Ireland and Avon had a slight ground frost in places. It was then sunny for a while in most places; cloud spread N'wards across much of S England by early afternoon, and rain followed during the afternoon and evening across S, Cent and E England. Showers developed in northern and western districts, and some became heavy and thundery. Many places in Ireland, Wales and Scotland had a sunny day. (Hull East Park 20.6C, Logan Botanic Garden 12.5C maximum, Katesbridge -0.6C minimum, Normanby Hall 19.2 mm, Ronaldsway 14.6 h.)

Much of central and eastern Britain was cloudy on the 19th with showers or outbreaks of rain; it was quite sunny in the W and SW of the UK and in parts of E Ireland, with a few showers. Brighter spells developing in the south soon led to some heavy, thundery showers in the afternoon and these continued into the evening. It was mostly quite cool - cold in many eastern districts, especially in E England. Temperatures approached the normal in some of the brighter areas, especially those that missed the showers. (Hereford 18.2C, Fylingdales 8.3C maximum, Kinbrace -1.5C minimum, Cromer 20.4 mm, Aberporth 13.9 h.)

There was a fair amount of rain over N England and Scotland on the 20th as pressure remained low over the UK , but rather brighter, though still showery, weather gradually extended NE'wards during the day. There was a low centred E of Wick at 1200 GMT of 1006 mb. Some of the showers were heavy and lengthy, and there was thunder in a few districts. The southeast became fairly sunny, though breezy, during the afternoon. It was mostly rather cool. (Gravesend and Helens Bay 18.3C, Balmoral 9.2C maximum, Bala 1.1C minimum, Fair Isle 17.6 mm, Manston 13.0 h.)

On the 21st high pressure built to the E of the British Isles, drawing a S'ly flow across all areas by the end of the day. Low pressure to the W of Ireland pushed some rain N'wards across Ireland and Scotland - although amounts in E and N Scotland were slight. It was a mainly sunny day across S England and Wales and these bright conditions extended N'wards during the day. (St James Park 20.9C, Inverbervie 11.5C maximum, Braemar -0.9C minimum, Magilligan 6.4 mm, Manston 13.7 h.)

A frontal system spread E'wards across all areas during the 22nd. Precipitation was largely confined to Ireland, Scotland and N England, however, and away from W Scotland and N Ireland amounts tended to be slight. Much of England and Wales became fairly sunny and very warm; the best of the sunshine was in the south and east, although the evening was rather cloudy again here. There was some thunder over eastern Scotland in the evening. (St James Park 24.9C, Fair Isle 12.0C maximum, Kielder Castle 4.4C minimum, Tulloch Bridge 16.0 mm, Odiham 11.8 h.)

High pressure became established over S areas of the British Isles on the 23rd. After a mild night across much of England (away from the south coast), Wales and S Ireland it became warm in these areas and in E Scotland. There was some mist and fog across Ireland at first with a lot of cloud over Scotland and Northern Ireland during the day, along with some rain. Much of southern Britain was fairly cloudy with a little drizzle in places, and coastal and upland fog in the southwest at first. Away from the south, though, many parts of England and Wales were sunny. (Hereford 23.3C, Fair Isle 11.9C maximum, Katesbridge 1.5C minimum, Kirkwall 13.8 mm, Morecambe 12.7 h.)

High pressure was centred over England and Wales (at around 1025 mb) on the 24th. After a mild night the day dawned with mist and fog over Ireland, Wales and S England. NW districts were mostly cloudy, with a little rain in places during the day. Elsewhere, extensive low cloud and mist affected many western and southwestern districts, especially near the coast. This only retreated slowly out to sea, persisting near many Irish Sea coasts, but much of the country was sunny and became very warm. (Pershore 26.6C, Fair Isle 11.5C maximum, Aboyne 5.5C minimum, Loch Glascarnoch 2.8 mm, Manston 14.1 h.)

Pressure remained high on the 25th and most places were sunny and warm or very warm, locally hot well away from most coasts. There was overnight mist and fog across Ireland and in many areas of England and Wales, while W Ireland had some breaks in the sunshine due to cloud during the day. Low cloud and mist affected some western and northwestern coastal areas at first. It was rather cloudy on Shetland, and shallow convective cloud developed sufficiently to limit sunshine for a time over the Midlands. (Aboyne 28.0C, Fair Isle 12.2C maximum, Loch Glascarnoch 6.3C minimum, Lerwick 0.6 mm, Kinloss 16.1 h.)

High pressure drew warm air off the continent on the 26th but by midnight a low, centre 1008 mb, had formed off S Devon. Away from N and Cent Scotland the day dawned after a mild night, especially so in W Ireland, W Wales, NW England and SW Scotland. E areas of Scotland, Ireland and N England had early mist and fog patches - otherwise it was sunny, and many places away from windward coasts became very warm or hot. There was some light rain and drizzle over the Northern Isles for a while. There were some showers across Ireland later in the day, while more general rain affected S Ireland in the evening - and rain that had reached SW England and the Channel Islands by midnight was the start of a thundery outbreak. (Lossiemouth 29.4C, Fair Isle 12.9C maximum, South Newington 6.3C minimum, Lerwick 0.4 mm, Morecambe 15.5 h.)

A shallow low moved from Devon to E Scotland during the 27th, leading to a cloudy day in many areas. To the E of the low it was a warm day - but was noticeably cooler to the W. Indeed, many northern and eastern areas were hot and sunny for some time, but outbreaks of rain and thunderstorms moved north across most of the country, followed by fairly sunny, but rather cooler and breezy weather in the south. Early in the day, heavy thunderstorms affected SW Engand, with heavy downpours and lightning striking properties. The Met Office said over the four-hour period from midnight to 04:00 there was a "notable" amount of lightning. Devon and Somerset Fire and Rescue Service reported strikes at eight properties, and a BT box on a telegraph pole was destroyed. Cornwall's fire service reported "properties and businesses" had been struck. The events were caught on camera by members of the public across the region. Cornwall Fire and Rescue Service said it began receiving calls "shortly after midnight" to properties which had been "struck by lightning, activating alarms and on some occasions causing small fires". There was large hail (about 20 mm in diameter) in the Huddersfield-Leeds and Durham-Newcastle areas. (Lossiemouth 27.3C, Fair Isle 13.2C maximum, Ravensworth 6.6C minimum, Levens Hall 52.6 mm, Manston 11.9 h.)

An area of low pressure moved away NE'wards from E Scotland during the 28th. The N half of the British Isles had a mainly mild night as rain cleared towards the NE to give a largely dry here - except for some light rain over Scotland. Across England, Wales and S Ireland rain pushed N'wards in the afternoon - with thundery outbreaks in parts of S England before midnight. Most areas had some sunny spells (with the best of the sunshine in East Anglia) although the day was generally rather cloudy at times in all areas. (St James Park 24.9C, Baltasound 11.0C maximum, Okehampton 6.0C minimum, Aultbea 10.0 mm, Shoeburyness 10.1 h.)

During the early hours of the 29th severe thunderstorms swept across SE England overnight, bringing intense thunder, lightning and heavy rain to the region. More than 120,000 flashes of lightning were recorded over northern France and south-east England in just 12 hours, according to the Met Office. A house in Staplehurst, Kent, was hit by lightning just after 0100 GMT, which exploded cables and set the roof on fire. In Folkestone, also Kent, another house was struck causing a power surge and total electrical failure to the home. A tower block in Stratford was struck by lightning twice; the strikes hit the Capital Towers shortly after 0100 GMT and were followed by further flashes. During the morning the rain moved N'wards with the storms moving NE'wards into the North Sea. Away from the far N of Scotland the day dawned after a mild night and frontal cloud and further rain the affected all areas at times during the day. In most areas it was a sunless day. (Frittenden 24.2C, Lerwick 10.1C maximum, Kinbrace 4.2C minimum, Upper Lambourn 21.4 mm, Manston 5.9 h.)

The 30th dawned rather misty in many areas of the UK with light rain and drizzle persisting in many areas after overnight falls across the British Isles. As pressure built across all areas during the day the rain and drizzle slowly faded away and, although it remained rather cloudy, most areas had some sunny intervals at times during the day. (Chillingham Barns 21.7C, Fair Isle 10.3C maximum, Lerwick 7.5C minimum, Wick Airport 11.0 mm, Guernsey Airport 9.7 h.)

There was mist and some fog patches by dawn across S areas of England, Wales and Ireland on the 31st - with a mild night in these areas and a cooler start to the day elsewhere. There was some light rain and drizzle at times overnight in parts of Wales, SW England and S Ireland - and there were further light falls in some places here during the day. It was a very sunny day across S Scotland and N England - with sunny spells over N Scotland and rather cloudier skies elsewhere. (Heathrow 23.0C, Fair Isle 11.9C maximum, Katesbridge 0.6C minimum, Llysdinam 9.8 mm, Leconfield 15.4 h.)

British Isles weather, June 2017

Rain and drizzle spread across Ireland and into W Scotland and N England before dawn on the 1st. During the day rainfall was largely confined to Scotland and Ireland, although falls were slight away from Ireland and SW Scotland. There was some early mist and a few fog patches over S, Cent and NE parts of England - after this cleared the day was largely a sunny one here and in Wales although some rain and drizzle affected W Wales and SW England in the evening. It was very warm in parts of SE England. (Gravesend and Heathrow 25.5C, Lerwick 10.9C maximum, Baltasound 2.6C minimum, Port Ellen 19.6 mm, Guernsey Airport 15.6 h.)

Overnight into the 2nd the rain spread across much of Wales and into E Scotland, with further showery falls to the W across Scotland and Ireland. During the day falls were mainly slight across Ireland and Scotland. The rain spread E across England during the day; ahead of the rain area sunshine and warm weather led to thunderstorms forming to the W of London; these subsequently moved NE'wards into S parts of East Anglia in the evening. (Gravesend 26.8C, Fair Isle 12.6C maximum, Castlederg 5.7C minimum, Andrewsfield 18.2 mm, Aldergrove 11.4 h.)

Overnight rain cleared E areas of England to give a mainly dry and sunny day here, except for some slight rain across Wales and some W parts if England later on the 3rd. Rain across Ireland later affected Scotland; these showery conditions spawned some thundery activity in many parts of Scotland during the day. Most parts of the British Isles reported sunny spells during the day, although W Ireland and Scotland (away from the SE) were cloudier. (Frittenden 22.2C, Baltasound 11.9C maximum, Braemar 0.2C minimum, Leconfield 24.8 mm, Morecambe 13.7 h.)

An area of low pressure moved towards W Ireland by 2400 GMT on the 4th. There was some overnight rain across Ireland and the Northern isles with lighter falls elsewhere. The day dawned sunny in most other areas, remaining sunny across N England, many areas of Wales and SE England. Elsewhere frontal cloud spread from the W and there were showers and isolated thunder in parts of Wales, the Midlands and SW England during the day. A Highland Games in a north-east village in Scotland had to be abandoned after a "mini tornado" swept through the site. Villagers in Cornhill, near Banff, had been enjoying the annual event at the playing fields on Saturday afternoon. After a spell of "beautiful" sunshine, the storm blew in, wreaking havoc on the park and lifting the first aid tent over a marquee and into the arena. No-one was seriously hurt. (Holbeach 20.7C, Lerwick 10.7C maximum, Kinbrace -0.1C minimum, Pembrey Sands 13.8 mm, Herstmonceux 12.5 h.)

An area of low pressure moved slowly from W Ireland at 0000 GMT to N Wales by 2400 GMT on the 5th. The result was an unsettled day with little sunshine away from Essex, Kent and Sussex. Rain, initially across Ireland, spread across much of Scotland, Wales and W England by mid-morning. As the day wore on it affected all areas although falls in East Anglia were slight until the evening. Over most of Scotland and Ireland the rain turned to showers; heavy showers over N Ireland and S Scotland turned thundery in places. At Capel Curig 83 mm fell in the 24 h from 0600 GMT and it turned windy across S England later as pressure fell. (Shoeburyness 19.7C, Cluanie Inn 10.9C maximum, Resallach 2.7C minimum, Capel Curig 68.6 mm, Manston 8.5 h.)

Widespread rain cleared only slowly towards the NE on the 6th, with the result that most places N of a line Belfast-Essex were dull all day. Showery weather followed the rain from the S. The rain was due to a low pressure system that gave a reading of 985 mb at the centre - possibly the lowest over England in June since at least 1958. The same system also gave the lowest MSL pressure in Reading/west London area since before 1949; the minimum MSL pressure reached 987.1 mb at 0342 GMT at the University of Reading while Heathrow in records back to 1949 had ever reported a lower June MSL pressure than 989.7 mb (on 9 June 1954). Power was restored to some properties in south Wales after hundreds were affected by cuts caused by strong winds and rain. Western Power Distribution said Monmouthshire had been worst hit, with more than 450 customers affected at the height of the problem. Rhondda Cynon Taff, Carmarthenshire, Caerphilly, Newport, Blaenau Gwent and Powys are also affected. ScottishPower has restored power to about 200 homes in Porthmadog, Gwynedd. The properties had been without power since 0900 GMT on Tuesday. They lost power due to an overhead line fault which engineers are working to fix. Meanwhile, firefighters rescued a man and a woman stranded in the middle of a swollen river near Waunfawr, Gwynedd, at 06:00 on Tuesday. The two campers had to be rescued after their tent washed away and they were left stranded on a small patch of land. The A482 Aberaeron to Ciliau Aeron in Ceredigion was shut due to a fallen tree but has since reopened Elsewhere, high winds and fallen trees caused problems on some roads. One lane was closed on the Severn Bridge to protect vehicles from being blown into adjacent lanes. In Vale of Glamorgan, part of the A4050 was closed after a tree fell on an ambulance near Bryn Hafren Comprehensive School in Barry. A section of the A483 in Carmarthenshire was also closed in both directions due to a fallen tree near Sugar Loaf Mountain, between Llandovery and Llanwrtyd Wells. A driver was killed after a tree fell and landed on his car following high winds. The man was driving through Odiham, Hampshire, on the A287 when the tree collapsed at 0617 GMT. A 42-year-old driver died after a tree hit his car as high winds and rain swept across parts of Scotland. The accident happened on the A85, two miles east of Gilmerton, Perthshire, at about 1900 GMT. (Hurn 17.8C, Blencathra 10.0C maximum, Okehampton 7.0C minimum, Edinburgh Botanic Gardens 65.2 mm, Guernsey Airport 13.5 h.)

Rain was slow to clear NE Scotland on the 7th with the Northern Isles having a dull day. Elsewhere there were sunny spells during the day although by midday a warm sector was bringing rain across S Ireland and Cornwall. This spread across Wales and SW England by the evening - with falls across most of England, Wales and parts of S Scotland by midnight. Heavy rain overnight led to flooding across Aberdeenshire and Moray, with people rescued and homes evacuated in the village of Portsoy. (Heathrow 20.9C, Kirkwall 9.9C maximum, Killylane 6.2C minimum, Wick Airport 38.2 mm, Glasgow 11.8 h.)

Outbreaks of rain were widespread on the 8th until the evening across most of England, Wales and Ireland - with the rainfall steadily moving N'wards into Scotland during the day and evening. Ahead of the rain many inland areas of N and Cent Scotland had a ground frost - with an air frost in most sheltered places. Heavy showers persistently developed over a period of several hours from early afternoon over Bodmin Moor and Dartmoor, streaming NE'wards in narrow lines across SE Wales and parts of the Midlands. Thunderstorms moved NE'wards over Sussex and Kent in the late evening. It was a dull day in Cent S England and across much of S Scotland and N Ireland. By 2400 GMT MSL pressure was down to 996 mb over NE Scotland. (Manston 20.5C, Lerwick 9.7C maximum, Altnaharra -2.3C minimum, Lough Fea 38.8 mm, Altnaharra 8.2 h.)

Low pressure led to a wet night into the 9th across Scotland; elsewhere showery outbreaks were widespread. The showers cleared to the E during the day and the rain slowly moved away from Scotland. An area of low pressure moved towards SW Ireland during the day, giving spells of rain over S Ireland in the afternoon - and across much of Ireland, Wales and SW England in the evening. (Holbeach 21.3C, Kinbrace 11.3C maximum, Shobdon 6.8C minimum, Lentran 26.4 mm, Leconfield 10.9 h.)

Pressure remained low to the W of Ireland during the 10th.

The former area was largely sunny during the day, while the Shetlands were dull. It was warm in the sunnier parts of S England and the Channel Islands. (Santon Downham 24.8C, Fair Isle 11.6C maximum, Aboyne 6.8C minimum, Capel Curig 30.8 mm, Jersey Airport 14.7 h.)

The low pressure centre to the W of Ireland moved towards the Western Isles by 2400 GMT on the 11th. The day was blustery with widespread showers across Ireland and Scotland. There were lesser falls of rain across Wales and some W areas of England, although other areas of England saw sunny spells during the day, and it turned warm in some parts of SE England. (Heathrow 23.9C, Blencathra 12.8C maximum, Drumnadrochit 7.9C minimum, Tyndrum 27.4 mm, Leconfield 9.4 h.)

Overnight into the 12th precipitation was largely confined to Scotland and N Ireland, with lesser falls over S Ireland and N England.

(Heathrow 20.9C, Salsburgh 11.8C maximum, Okehampton 8.8C minimum, Cluanie Inn 31.0 mm, Channel Islands 12.3 h.)

Into the 13th there was light rain overnight across Wales and some Cent areas of England. A cloudy day followed In most areas, especially in W parts of the British Isles. An exception to this was S England, were there were widespread sunny spells - it turned warm here as a result. Further rain fell at times across Scotland during the day. (Heathrow 24.8C, Fair Isle 12.7C maximum, Exeter Airport 4.7C minimum, Achnagart 19.8 mm, Hurn 15.2 h.)

High pressure towards the E on the 14th weakened as fronts spread E'wards across W areas of the British Iles during the day. There was a little rain across parts of Scotland before dawn - and some misty conditions developed in SW England and S Ireland by dawn. There was some light rain during the day across N Scotland, while rain and drizzle spread E'wards across Ireland and into SW Scotland in the evening. Some E areas had a sunny day, as did S England. It turned very warm in SE England. (Heathrow 27.1C, Harris Quidnish 13.8C maximum, Exeter Airport 5.6C minimum, Achnagart 4.8 mm, Hurn 15.1 h.)

Fronts spread some rain E'wards on the 15th, with falls mostly across Ireland, Scotland and N England.

(Manston 26.0C, Cluanie Inn 13.7C maximum, Exeter Airport 7.0C minimum, Tyndrum 22.0 mm, Reading University 12.9 h.)

High pressure spread NE'wards during the 16th, reaching 1028 mb over SW England and the Channel Islands by midnight. The day dawned rather misty in parts of Ireland and most areas across the British Isles then had a cloudy day - with some light rain in N areas at times. Across S areas of England, Wales and Ireland it was a sunny day. (Heathrow 24.3C, Cluanie Inn 13.6C maximum, Porthmadog 8.0C minimum, Harris Quidnish 6.4 mm, Guernsey Airport 14.1 h.)

High pressure dominated the weather on the 17th across S parts of the British Isles. A cold front gave some light rain during the day across N and W Scotland. Elsewhere, after a misty start to the day in some S parts of Britain and Ireland, most places had a sunny day and it turned hot in Cent, E and SE England away from the coasts. (Heathrow 30.1C, Fair Isle 13.3C maximum, Libanus 8.8C minimum, Achnagart 24.2 mm, Boulmer 16.0 h.)

British Isles weather, July 2017

A weak ridge of high pressure early on the 1st gave way to a W'ly flow during the day as a depression moved E'wards to the N of Scotland - MSL pressure down to about 999 mb on Shetland by 2400 GMT. After a warm night in parts of S England (minimum temperatures above 15C) with some light rain in E England, further light rain spread across Ireland by midday and then into E Scotland and Wales by the evening, but with falls lessening further E and S. It was windy across N Scotland, while most places away from Ireland and NW Scotland had some sunny spells ahead of the advancing cloud. (Wellesbourne 24.0C, Lerwick 11.6C maximum, Altnaharra 0.1C minimum, Stonyhurst 4.2 mm, Guernsey Airport 11.9 h.)

Some light rain and drizzle moved across the Cent parts and the SE corner of England before noon on the 2nd, leaving a mainly sunny day across England once some early mist had cleared SW England. Across Scotland there was overnight rain in the N, with further light rain spreading from the W across much of Ireland, Scotland and into parts of Wales during the day. It was a dull day, as a result, in W Scotland and NW Ireland. (Thorney Island 24.1C, Cluanie Inn 11.4C maximum, Killylane 7.3C minimum, Cassley 21.8 mm, Shobdon 14.5 h.)

Frontal rainfall moved away from Scotland and N Ireland during the morning of the 3rd, with lesser falls across parts of S England for a while during the day. The weak frontal system that brought this rain became slow-moving and later in the day pushed N'wards, intensifying over Ireland (due to a wave depression located W of Ireland by 2400 GMT) where there was widespread rain in the N in the evening. It was misty in SW England around the coasts in the morning, and also here and in parts of S Ireland in the evening. It was a dull day across Ireland and in many parts of SW England. (Heathrow 25.1C, Fair Isle 12.9C maximum, Drumnadrochit 6.3C minimum, Cluanie Inn 5.8 mm, Tiree 11.0 h.)

The wave depression moved across Ireland and into the Isle of Man on the 4th. This led to widespread and, in places, heavy rain during the day over N Ireland and S Scotland - and in neighbouring areas - during the day. As the low moved E'wards, so too did the heaviest rain. N and Cent Scotland had a largely dry day with sunny spells across N Scotland. S England was warm but rather cloudy - after some early rain and coastal fog in the SW. Overnight it had been quite warm in S Wales and SW England. (Manston 25.0C, Salsburgh 11.4C maximum, Altnaharra 1.1C minimum, Spadeadam 42.2 mm, Stornoway 13.8 h.)

It was a warm day on the 5th over most of S and Cent England, Wales and East Anglia - with long, sunny spells over S England. N Ireland, N England and S Scotland had a cloudy day with rain and drizzle that tended to die out during the day - but then intensified over N Ireland and SW Scotland later in the evening. Remaining areas of Scotland had a mainly dry and sunny day. (Heathrow 29.5C, Fylingdales 12.6C maximum, Kinbrace 1.8C minimum, Albemarle 4.6 mm, Shoeburyness 15.1 h.)

The 6th dawned with warm, misty conditions in many parts of Ireland, Wales and Cent and S England; minimum temperatures overnight were in the range 15-18C in many parts of Cent S and SE England. Much of England and Wales had sunny spells during the day and became hot, locally very hot. Thunderstorms affected some areas, especially East Anglia and NE England during the day, and Lincolnshire and NE Midlands in the evening. Scotland and Northern Ireland were mostly quite warm and fairly cloudy, with some widespread rain overnight and in the N and W during the day; the rain moved slowly E'wards during the day. (Heathrow 32.2C, Fair Isle 12.8C maximum, Altnaharra 5.1C minimum, High Mowthorpe 35.4 mm, Jersey Airport 13.8 h.)

Parts of Cent S and SE England, East Anglia and the East Midlands, and a few locations from Lancashire to S Wales had overnight minimum temperatures above 15C on the 7th, with 17C in parts of SE England. The day dawned misty in parts of Wales and N England - following some overnight rain in places here and in both Scotland and Ireland. It was a sunny day in Cent S and SE England, the Channel Islands and parts of East Anglia while temperatures rose to above 28C in the London area. Elsewhere, it was rather cloudy with light rain and drizzle that slowly moved SE'wards across Ireland and Scotland, later affecting Wales and parts of the Midlands. (Heathrow 30.1C, Altnahinch Filters 12.7C maximum, Shobdon 9.5C minimum, Dyce 13.2 mm, Jersey Airport 14.6 h.)

Minimum temperatures overnight into the 8th remained above 15C overnight SE of a line The Wash-SW Cornwall. Despite cloudy skies in places much of this area then had a warm day with temperatures reaching 26C and above in the London area. It was a sunny day across N England, N Wales, N Ireland and S Scotland, but a cool and cloudy day with some rainfall across N Scotland due to a low pressure system centred N of Shetland by late evening. (Teddington Bushy Park 27.3C, Harris Quidnish 12.5C maximum, Katesbridge 1.8C minimum, Harris Quidnish 20.2 mm, Boulmer 15.6 h.)

Fronts made slow progress SE'wards on the 9th, with a shallow wave depression forming over Cent Scotland along one of them by 2400 GMT. The main rain areas associated with the fronts ,moved from N and W Scotland overnight to S Ireland and N parts of England and Wales by the evening. It brightened up during the day in across N Scotland but much of N Ireland and S and Cent areas of Scotland remained dull. The best of the sunshine was to be found over parts of S England - after a warm night here and in S Wales a warm day followed with temperatures reaching 26C in parts of SE England. Later in the day some heavy showers developed over parts of S Wales, the Midlands and in some E areas of England. (Heathrow 28.4C, Salsburgh 12.7C maximum, Katesbridge 5.9C minimum, Achnagart 16.4 mm, Hurn 14.4 h.)

Fronts led to a cloudy day in most areas on the 10th although it was a warm and sunny day in much of SE England. Elsewhere, under cloudy skies, there were outbreaks of rain and showers overnight and during the day, with thunderstorms reported in the afternoon over parts of East Anglia. (Gravesend 27.0C, Carterhouse 12.8C maximum, Tulloch Bridge 4.3C minimum, Manston 24.6 mm, Lerwick 15.3 h.)

On the 11th a shallow low moved E'wards towards Dorset - centred at 1005 mb here by 2400 GMT. As a result much of England, Wales and S Ireland had widespread rain that slowly moved towards the E, clearing S Ireland by late evening. Falls were heavy in parts of SW England and S Wales. Across Scotland there were showery outbreaks, but also some long sunny spells in SW Scotland (and also in parts of N Ireland). As the low continued to move E'wards, 24-hour rainfall totals ending at 0600 GMT on the 12th included 40.8 mm at Kenley, 39.2 mm at Chivenor and 36.6 mm at Heathrow. (Manston 21.5C, Bingley 11.8C maximum, Port Ellen 3.6C minimum, Chivenor 34.6 mm, Magilligan 14.7 h.)

Overnight rain affected parts of NE Scotland into the 12th, while a large area of rain affected places SE of a line Cardiff-The Wash, the rain gradually moving away SE'wards after producing some heavy falls in SE England. This wet area had a mild night - but it was quite cool overnight in parts of NW Scotland and Cent Ireland. The rain had cleared the SE by late morning and a ridge of high pressure then spread from the W, MSL pressure centred at 1024 mb over London by 2400 GMT. Once the rain and associated cloud had cleared, there were sunny periods in SE England; across much of Scotland, Ireland and N England the day was very sunny. (Castlederg 23.1C, Fair Isle 13.6C maximum, Kinbrace 1.6C minimum, Shoeburyness 25.4 mm, Tiree 16.0 h.)

Overnight into the 13th it was largely dry, although mist patches formed across parts of Ireland and there was some light drizzle in S Ireland in places. A cloudy day followed here as a band of rain spread across Ireland, Scotland, N England and N Wales during the afternoon and evening; ahead of the rain it was also rather cloudy, except in the far SE of England and the Channel Islands. There were also a few showers in some Cent and E parts of England ahead of the main rain area, while temperatures reached 20-22C across much of E Scotland and in many areas of England. (Nantwich 23.7C, Harris Quidnish 14.3C maximum, Aboyne 2.8C minimum, St Bees Head 5.8 mm, Jersey Airport 14.3 h.)

Many areas of the UK had some slight rain or drizzle into the 14th, but then a largely dry - if rather cloudy - day followed for many areas. By early evening frontal rain had spread E'wards across Ireland and much of W Scotland - with subsequent falls in E Scotland, NE England and East Anglia by midnight. (Thorney Island 22.3C, Cluanie Inn 12.8C maximum, Drumnadrochit 8.6C minimum, Lough Fea 14.8 mm, St Athan 12.4 h.)

The 15th was unusually dull for July with some rain or drizzle at times across the British Isles, although in most places falls were light. There was some mist or fog in coastal and hilly areas of SW England with misty conditions here and later in S Ireland reflecting a moist SW'ly airflow. It was a warm day in parts of E Ireland. (Carlow, Oak Park 25.3C, Fair Isle 13.1C maximum, Cluanie Inn 9.8C minimum, Achnagart 27.6 mm, Jersey Airport 8.1 h.)

the 16th dawned after a mild night in many parts of England, Wales and S Ireland with overnight minimum temperatures of 17-19C in S parts of England and Wales. There was overnight rain and drizzle in Ireland, Wales and W parts of England; during the day precipitation, mostly slight, was largely confined to S and Cent England, Wales and N Scotland. NW Wales, E Scotland and much of Ireland had a sunny day. Despite the cloudy conditions, temperatures reached 25-26C around the London area and in Kent and Essex. (Writtle 26.4C, Cluanie Inn 13.3C maximum, Aboyne 7.7C minimum, Andrewsfield 7.2 mm, Ronaldsway 13.9 h.)

There was light rain across the Northern Scotland overnight and then the Northern Isles at times throughout the 17th. Elsewhere the day was generally dry. After a warm night in the extreme S of England (overnight minimum temperatures remained above 15C in many places close to the English Channel) temperatures rose above 25C in many parts of Cent and E England on a day with generally widespread sunshine. Away from S England, S Wales and W and N Scotland, many places had 12-15 h of bright sunshine. (Otterbourne Water Works 27.4C, Fair Isle 12.5C maximum, Sennybridge 3.7C minimum, Resallach 2.2 mm, Morecambe 15.4 h.)

The 18th dawned with the British Isles under an anticyclone, and this led to a warm night across S parts of England and Wales with minimum temperatures of 16-18C in places. A warm front pushed N'wards across the English Channel in the morning, reaching N England and N Ireland by the end of the day. Showers and thunderstorms along a trough behind this front affected SW England and the Channel Islands during the afternoon, and some other southern counties in the evening. Some of the storms were severe, with hail and torrential rain in places; a flash flood hit Coverack (SE Cornwall) while in Reading 36 mm of rain fell in an hour during evening thunderstorms. Residents in Coverack, on the Lizard Peninsula, reported roads being blocked and hailstones the size of 50 pence pieces smashing windows. Heavy rainfall hit at about 1400 GMT and about 50 properties are estimated to be affected by the flooding, but no injuries were reported. Torrential rain also caused flooding at schools, hospitals and roads in north Wales; heavy rain caused flash flooding in the Rhyl, Prestatyn, Abergele, Rhuddlan and St Asaph areas. Theatre and support areas at Abergele Hospital were affected by the flooding, as torrential rain caused leaks, but the health board said patients and clinical services were not affected. The day was warm with temperatures reaching 26C as far N as the Nairn area - with much of Scotland and NE Ireland having a very sunny day. (Otterbourne Water Works 28.8C, Fair Isle 14.4C maximum, Loch Glascarnoch 3.9C minimum, Reading University 42.4 mm, Stornoway 15.9 h.)

Overnight into the 19th minimum temperatures above 15C were widespread across Ireland and much of England and Wales (apart from NE England). Thunderstorms moved from S England towards Norfolk, clearing from the Norfolk coast during mid-morning. The owner of a flat which was hit by lightning in Bradwell, Essex, said he had a lucky escape; the roof of the property was badly damaged during thunderstorms in the morning. In Kent, at the height of the storms - between 0130 and 0230 GMT - fire crews in Tunbridge Wells were called out 60 times in 60 minutes. Residents reported up to a metre of water in some properties although no rescues were needed. In Herne Bay a house was struck by lightning, damaging the roof, and at 0200 GMT East Sussex Fire and Rescue Service was called out to the Three Ponds Industrial Estate, on the outskirts of Newhaven, following another lightning strike which developed into a fire. Rain and drizzle fell across Cent and S Ireland before dawn. More widespread and heavier rain moved across Ireland and into W Britain during the day. It was warm across N and E England and before thunderstorms affected parts of Wales, and later N England. An area of storms early in the day led to a lightning strike on a Gwynedd pub that caused a fire in a chimney stack; fire crews were called to the Peniarth Arms in Bryncrug, near Tywyn, and the fire was put out at 0230 GMT. By midnight most areas had seen some rainfall as fronts moved across the British Isles from the W. As a result, the best of the sunshine was to be found in East Anglia and in parts of N Scotland - ahead of the rain. (Cromer 27.8C, Fair Isle 13.2C maximum, Braemar 5.4C minimum, Rhyl 39.8 mm, Stornoway 10.7 h.)

All areas saw some rainfall overnight into the 20th, with some thunder heard in NE Scotland; overnight minimum temperatures remained above 15C in the E half of England while in parts of Cent Ireland grass minimum temperatures dropped below 5C. The rain cleared towards the E during the mid-afternoon in England but lingered across NE Scotland. Other areas of rain spread across Ireland during the afternoon and evening with a low becoming centred close to Valentia (995 mb) at 2400 GMT and another low (1001 mb) W of Fair Isles at the same time. N and Cent Scotland was rather cloudy as a result. (Weybourne 23.8C, Kinbrace 12.9C maximum, Castlederg 6.2C minimum, Wick Airport 36.2 mm, Tiree 12.0 h.)

Low pressure remained centred across Ireland throughout the 21st. As a result it was a wet day across Ireland, with some heavy rainfall also across Wales, W England and SW Scotland. Several hours of rainfall led to large accumulations, especially over high ground. Much of E England remained dry - although some light rain fell in SE England and East Anglia in the late evening. There was some overnight rain in N Scotland - but it remained mainly dry here during the day. It was a sunny day in East Anglia and SE England, and also across N Scotland but the rain led to some flooding in Cornwall and Devon. (Coningsby 23.1C, Tredegar Bryn Bach Park 14.0C maximum, Dalwhinnie 2.2C minimum, Tredegar Bryn Bach Park 69.4 mm, Kirkwall 14.6 h.)

There was a misty start to the 22nd in parts of N Scotland - it then turned warm here with temperatures as high as 22C on the mainland despite rather cloudy skies at times. Overnight, rainfall areas moved E'wards across England although the night was generally mild here. There was mist and some fog patches in Cent England and also in areas of Ireland by dawn; during the day rain moved N'wards over the S and Cent Scotland from N England; this was heavy and thundery rain in areas bordering the Solway Firth and S Scotland remained generally dull. Another area of rain with isolated thunder moved slowly north across much of southern England and into the Midlands and East Anglia, whilst other districts had some sunshine with a scattering of heavy, locally thundery, showers. In Scotland, the village of Eastriggs was affected by flash flooding as torrential rain affected parts of south-west Scotland. A British Airways plane sustained as many as 46 holes during a lightning strike just after takeing off from Heathrow - but despite the damage the carrier continued its nine-hour journey to Chennai. (Hull East Park 22.5C, Salsburgh 14.0C maximum, Shobdon 7.0C minimum, Carlisle 50.2 mm, Aberdaron 12.0 h.)

By dawn on the 23rd there was widespread mist and fog patches in S and E parts of England and Scotland. Low pressure moved E away from N England during the morning, introducing a N'ly flow to most areas. As a result Ireland was largely dry overnight and during the day; the UK had widespread rain that gradually moved towards the E. It was a dull day in E Scotland , bright in W Scotland and W Ireland, and with sunny periods elsewhere. (Derrylin Cornahoule 22.7C, Fair Isle 14.1C maximum, Mona 6.3C minimum, Sutton Bonington 18.6 mm, Cork Airport and Tiree 12.4 h.)

A N'ly flow on the 24th, accompanied by fronts over the North Sea and E coasts, led to a dull and cool day in E parts of the UK, with some rain that gradually became increasingly confined to E England. Further W it was brighter, largely dry and, in places, very sunny. (Tyndrum 24.5C, Fylingdales 11.5C maximum, Resallach 6.1C minimum, Fylingdales 25.0 mm, Edinburgh Gogarbank 15.4 h.)

Overnight into the 25th there was slight rain in East Anglia and NE Scotland. There was a misty dawn across much of England, Wales and Ireland and although it turned drier in E England rain lingered in parts of the Northern Isles for much of the day. Rain broke out over Aberdeenshire in the late evening and it was a dull day across much of E and N Scotland. Warm conditions in sunny spells over S Wales and the W Midlands led to some thundery outbreaks here in the afternoon. Frontal rain and drizzle spread into W Ireland and Cornwall in the evening. 3 mm of rain fell in Valentia in the 12 hours ending 1800 GMT. (Hereford 26.2C, Wick Airport 13.1C maximum, Achnagart 5.5C minimum, Marham 3.0 mm, St Athan 14.0 h.)

Fronts crossed the British Isles from the W on the 26th, bringing spells of rain to all areas an introducing a W'ly flow. Dawn followed a warm night in SE Ireland, SW England and S Wales. After a misty start to the day in E England ahead of the rain area, blustery winds spread to most areas. It was a dull day in S England, but turned sunny behind the rain across S Ireland and W Wales. A cold front gave a band of heavy rain in places in some N and Cent areas, while thundery showers crossed Northern Ireland to SW Scotland, NW England and N Wales. Across W Scotland the rain and strong winds led to some travel delays, and certain Hebridean ferries were cancelled. (Nantwich 23.7C, Fair Isle 13.0C maximum, Altnaharra 5.6C minimum, Logan Botanic Garden 37.4 mm, Cork Airport 10.2 h.)

A W'ly flow with embedded troughs on the 27th led to a day of sunshine and showers, although it was mainly dry overnight in E England. The Northern Isles saw the best of the sunshine with long, sunny spells here. The showers turned thundery later in the day over parts of Cent and E England. (Heathrow 22.2C, Dalwhinnie 13.9C maximum, Aboyne 4.7C minimum, Bainbridge 21.2 mm, Lerwick 12.9 h.)

Low pressure remained centred to the W of Scotland throughout the 28th leading to another day with shsowres and sunny intervals across the N half of the British Isles. Rain and showers affected southern areas also, before more general rain and drizzle, the result of a weak low and associated fronts, crossed S areas from the W later in the day. It was a dull day across S England and S Wales and it turned quite windy in many places during the day. (Writtle 23.4C, Cluanie Inn 14.3C maximum, Tain Range 7.8C minimum, Kielder Castle 29.8 mm, Lerwick 9.4 h.)

The 29th was an unsettled day, dominated by an area of low pressure located close to NW Scotland. Nw areas, including Ireland, were showery but it was largely dry in E Scotland and for most of N Wales and N England. SE England had some overnight rain, and then further rain spread NE across S England, and later into Wales and the Midlands; this was associated with a shallow low and its fronts - centre 1002 mb over the E Midlands at 2400 GMT. (Manston 23.1C, Dalwhinnie 12.5C maximum, Aboyne 4.8C minimum, Achnagart 49.0 mm, Boulmer 7.9 h.)

Cyclonic conditions continued to prevail on the 30th due to low pressure centred just to the W of Scotland throughout the day. The SE corner of England had a warm night under a weak warm sector. Early in the day it was showery in the N and W and wet over much of England and Wales, with particularly heavy rain affecting parts of Surrey, London and surrounding areas, turning thundery as it approached the Essex and Suffolk coasts. The rain cleared towards the NE after dawn and a showery day followed in most areas. A few showers turned thundery in the afternoon, especially over Northern Ireland and parts of E England. A persistent convergence zone over the centre of Cornwall and Devon led to prolonged heavy showers, and a stream of showers was carried into the S Midlands. The best of the sunshine was to the SE of London and on Orkney. In Derbyshire the Y Not festival was curtailed after heavy rain led to very muddy conditions underfoot. (High Mowthorpe 21.7C, Fair Isle 15.2C maximum, Katesbridge 7.8C minimum, Okehampton 84.2 mm, Kirkwall12.2 h.)

Persistent low pressure on the 31st to the W of Ireland led to another day of widespread sunshine and showers, particularly towards the W and NW of the British Isles. Some of the showers turned thundery in NW areas and many showers tracked from the SW across the Midlands, with SE England remaining largely dry. (Cavendish 23.8C, Fair Isle 15.2C maximum, Kinbrace 5.9C minimum, Lake Vyrnwy 21.4 mm, Guernsey Airport 13.1 h.)

British Isles weather, August 2017

Overnight into the 1st it was a warm night in parts of Cent S England close to the coast, while some rainfall occurred across Wales, N England and Ireland in particular. After a misty dawn in areas of E and S England, rain and showers were widespread during the day, heavy in places and with thunder later in the day in parts of N Ireland, E and S Scotland and the NE Midlands. (Gravesend 24.5C, Tyndrum 15.2C maximum, Kinbrace 4.4C minimum, Morecambe 29.0 mm, Shoeburyness 12.8 h.)

A depression moved towards W Ireland during the 2nd (centred 992 mb close to Belmullet by 2400 GMT), pushing fronts across all areas of the British Isles by that time. By dawn rainfall was widespread across Ireland, Wales and SW England - while minimum temperatures remained above 15C in parts of S England ahead of the rain. By the late evening only Shetland remained dry - while the highest temperatures occurred across Wales and parts of E Ireland. It was a dull day across most of England - the best of the sunshine occurred in NE Scotland ahead of the fronts and in a few clear spells behind the rain across Ireland. (Hawarden 22.9C, Inverbervie 15.8C maximum, Aboyne 4.5C minimum, Guernsey Airport 52 mm, Lerwick 10.4 h.)

Conditions overnight into the 3rd were generally mild, especially across S England. Rain and showers were widespread overnight, and across Ireland and both W and N areas of the UK during the day. It was rather cloudy across N Scotland as the rain-bearing depression took some time to clear from here - otherwise the best of the sunshine was to be found in many places close to the North Sea, from SE Scotland S'wards. (Holbeach 23.0C, Lerwick 13.9C maximum, Baltasound 7.9C minimum, Capel Curig 35.8 mm, Charterhall 7.9 h.)

A showery NW'ly flow on the 4th brought showers to much of Scotland and Ireland, but with only a few falls of rain further E and S after dawn. Much of Scotland remained cloudy throughout the day, with the best of the sunshine being over N Wales, the N Midlands and S areas of N England. (Gravesend 23.1C, Fair Isle 12.9C maximum, Killylane 10.1C minimum, Harris Quidnish 17.2 mm, Leconfield 11.9 h.)

Pressure rose on the 5th, reaching 1024 mb on Scilly at 2400 GMT, but to the N the surface flow from the NW remained generally showery. These showers lessened later as pressure rose, but thundery activity was reported from late morning onwards from parts of Cent S and SE England, through the Midlands and East Anglia, into NE England and SE Scotland. Most places had sunny spells at times during the day, with the sunniest conditions to be found over Cornwall and the Channel Islands and in places close to the northern end of Irish Sea. (Thorney Island and Writtle 21.9C, Lerwick 12.0C maximum, Katesbridge 1.9C maximum, Kielder Castle 16.6 mm, Guernsey Airport 13.0 h.)

Low pressure centred close to NW parts of the British Isles on the 6th pushed frontal cloud and rain from the W across many areas, although much of the Northern Isles, East Anglia, the Midlands and Cent and SE England remained dry. Overnight there were a few showers across N Scotland, while by dawn rain had spread across much of Ireland. Parts of N and Cent Scotland, away from the coasts, had a cool start to the day - although during the day temperatures rose here in places to the same level as across parts of S England and S Wales. The best of the sunshine was to be found on Shetland and in the extreme SE corner of England, along with the Channel Islands. (Cavendish 23.0C, Lake Vyrnwy 13.4C maximum, Kinbrace 1.9C minimum, Capel Curig 35.2 mm, Guernsey Airport 13.7 h.)

Low pressure remained centred close to the Western Isles on the 7th, giving showery conditions across N Scotland that gradually pushed S'wards, with falls in N England later in the day. Further S, overnight frontal rain cleared E England in the late morning - to be followed by brighter conditions. A lingering front over S England led to cloudy skies and outbreaks of rain here at times during the day, with some of the outbreaks being heavy in intensity. The best of the sunshine was generally to be found around the Irish Sea coastlines. (Holbeach 22.7C, Lerwick 14.2C maximum, Baltasound 5.0C minimum, Eskdalemuir 21.4 mm, Aberdaron 12.2 h.)

A N'ly flow developed on the 8th across all areas. Overnight there was rain across much of Cent England and N Scotland - with further showers across Ireland and parts of Scotland during the day. The overnight rain across England spread NW'wards over most of northern England. It was heavy in places, with some flooding in parts of north Lincolnshire and East Yorkshire later in the day and overnight and led to a cool day across NE England. Heavy showers fell over Wales, SW England and in parts of E England - these were thundery in places. (Frittenden 23.0C, Emley Moor 12.1C maximum, Aboyne 3.1C minimum, Stowe 48.0 mm, Tiree 12.4 h.)

High pressure built from the W during the 9th. During the day, rain cleared S'wards from N England and by mid-evening had cleared from much of Cent England. By mid-evening, there was a narrower rainband, still with some heavy falls, from the Isle of Wight through London to S parts of East Anglia. Thunderstorms affected parts of the Channel Islands around dawn. N parts of England, along with parts of Ireland and N Scotland, had a few showers during the day - with the best of the sunshine to be found in Cent and S Ireland, SW Scotland and W Wales during the day. It was cool in those E areas of England where the rain persisted for many hours. (Glasgow 20.5C, Monks Wood 13.3C maximum, Resallach 3.6C minimum, Kenley 44.6 mm, Glasgow 13.5 h.)

The 10th was a mainly dry day - with some exceptions. The extreme SE corner of England had early rain that finally cleared during the late morning, while frontal cloud brought rain across most of Ireland in the evening - the rain later reaching SW Scotland. Parts of N Scotland also had some rainfall during the day. As a result, the sunniest locations tended to lie across Wales N and Cent areas of England. (Hereford 22.8C, Cluanie Inn 13.9C maximum, Swyddffynnon 2.6C minimum, Manston 10.8 mm, Boulmer and Morecambe 14.0 h.)

Overnight into the 11th rain in the W spread into parts of Wales and E Scotland. It was rather misty in places by dawn in parts of the Midlands and Cent S England. During the day the rain moved SE'wards although falls tended to become less towards the SE of England. Although it brightened up in places in the W in between spells of rain, the best of the sunshine occurred in SE England. (Cavendish 23.8C, Liscombe 14.9C maximum, Shobdon 4.0C minimum, Achnagart 30.0 mm, Shoeburyness 10.6 h.)

Light rain and drizzle affected many areas at times on the 12th, following a warm night in many parts of S England. The Midlands, East Anglia and much of SE England remained largely dry during the day. (Frittenden 23.5C, Fair Isle 13.5C maximum, Loch Glascarnoch 6.9C minimum, Blencathra 11.8 mm, Tiree 9.8 h.)

Parts of N and Cent Scotland had some light rain overnight into the 13th, while the day dawned with some mist and fog patches in parts of Wales and the Midlands. Further showers occurred across areas of Scotland during the day; elsewhere the day was largely dry until rain spread from the SW into S Ireland in the afternoon, later spreading to most of the island and into SW Scotland in the evening. 8 mm fell at Sherkin Island in the 24 hours ending 1800 GMT. It was a sunny day in many areas of England. (Frittenden 23.8C, Dalwhinnie 12.7C maximum, Katesbridge 0.5C minimum, Kinlochewe 5.0 mm, Heathrow 12.5 h.)

Frontal rainbands moved E-NE'wards across all areas during the 14th, although much of East Anglia and SE England remained dry until the evening, with the best of the day's sunshine here as a result. Scotland remained rather cloudy and dull, but brighter spells followed the rain across Ireland later. It was a warm day in SE England. (Gravesend 25.0C, Fair Isle 13.7C maximum, Aboyne 3.9C minimum, Killowen 31.6 mm, Shoeburyness 11.0 h.)

The 15th was a showery day over W Ireland, N England and Scotland - following some overnight rainfall. Further S the overnight rain had largely cleared by dawn to give a sunny day, especially across many parts of Wales and W England - although there was some mist around dawn in some Cent areas. One person was rescued from a car caught in flood water in Aberdeenshire. The incident happened in Inverurie on the B993 at about 0500 GMT after a spell of heavy rain. (Shoeburyness 24.6C, Lerwick 14.8C maximum, Altnahinch Filters 8.4C minimum, Fair Isle 28.4 mm, Aberdaron 13.2 h.)

It was largely dry across the UK overnight into the 16th, but by dawn light rain was falling across many parts of Ireland. This soon spread across Scotland with falls then moving E'wards into Wales and many parts of England - although east Anglia was still dry by 2400 GMT. The best of the sunshine was to be found in E England and East Anglia as a result. (Heathrow 23.6C, Harris Quidnish 14.4C maximum, Aboyne 3.3C minimum, Lough Fea 15.0 mm, Leconfield 9.0 h.)

Low pressure close to NW Scotland on the 17th was associated with frontal systems that brought cloud and rain to many areas overnight and during the day, and blustery winds to N Scotland. Parts of Wales and N England had some thundery outbreaks overnight and although the bulk of the rain had cleared into the North Sea by midday, further showers followed from the W in many areas. Most areas had some sunny spells - the best of the sunshine occurred in E Scotland, while parts of E England turned quite warm. (Cavendish 25.4C, Dalwhinnie 15.5C maximum, Katesbridge 5.0C minimum, Trawscoed 30.0 mm, Edinburgh Gogarbank 12.5 h.)

With low pressure close to, or over N Scotland on the 18th (centre 995 mb close to Wick at 1200 GMT), the day was generally unsettled and rather blustery at times across N Scotland. Outbreaks of rain affected many areas overnight. During the day showers developed from the W - some with hail and thunder during the afternoon over parts of England. Further rain affected Wales, the Midlands and East Anglia in the afternoon and evening. Away from N and Cent Scotland most areas had sunny spells at times during the day. (Cavendish 22.9C, Dalwhinnie 12.0C maximum, Kinbrace 6.1C minimum, Fyvie Castle 35.2 mm, Ronaldsway 10.9 h.)

Many places had showery outbreaks during the 19th, especially in W areas of the British Isles and across N Scotland - although it was noticeably drier and less cloudy by comparison across much for the Midlands, East Anglia and in Cent S and SE England. The sunniest conditions occurred here as a result, while some thunderstorms affected W Ireland shortly after dawn. (Manston 21.3C, Leek 13.5C maximum, Santon Downham 7.3C minimum, Cluanie Inn 39.6 mm, Odiham 10.8 h.)

A weak ridge of high pressure meant that the driest areas tended to be in E parts of the UK on the 20th - at least until the evening. A NW'ly flow gave some rain and drizzle to parts of N and W Scotland at first, while by midday frontal cloud had brought rain from the SW across much of Ireland and into SW England and S Wales. By midnight this rain was affecting many places S of a line Malin Head-Ipswich with temperatures struggling to reach 16C in parts of S Ireland and S Wales. (Cavendish 21.8C, Fair Isle 13.2C maximum, Katesbridge 5.1C minimum, Resallach 18.2 mm, Leuchars 10.2 h.)

Rain and misty conditions across much of Ireland and S Britain at first on the 21st steadily edged N'wards during the day. Under the rain the night was mild, but it was cooler to the N - with a ground frost in parts of Cent Scotland. Although the rain cleared from the S later in the day it remained misty here and into the Midlands in the evening. Ahead of the rain area there were sunny periods, especially across NE Scotland. (Usk No.2 24.4C, Fair Isle 13.8C maximum, Tulloch Bridge 2.0C minimum, Shoreham 12.4 mm, Kirkwall 9.1 h.)

The 22nd dawned with widespread mist and fog patches across England, Wales and E Ireland following a night with widespread rainfall across N Ireland, N England and S Scotland. This rain moved slowly N through Scotland during the day, with another area of rain, especially heavy in parts of N Ireland, moving NE'wards through Ireland during the day. Away from Cornwall and Shetland the day was largely cloudy - with a few showery outbreaks of rain over England and Wales. Thundery outbreaks occurred in the evening over E Ireland and the Isle of Man, and in parts of Cent S England. Later in the day (and into the next morning) more than 120 people had to be rescued in Northern Ireland after being trapped by flooding. The NW was worst affected, particularly Londonderry, as well as other parts of the county and Tyrone. Firefighters rescued 93 people who were trapped by flood water in their cars or homes. At one point, the fire service got an emergency call every 45 seconds. The coastguard rescued more than 30 people, with helicopters being brought in from Scotland, Wales and Sligo. All flights to and from City of Derry Airport were cancelled for Wednesday. (Jersey Airport 26.6C, Fair Isle 13.8C maximum, Baltasound 4.5C minimum, Lough Fea 55.2 mm, Lerwick 11.8 h.)

Areas of heavy rain moved N'wards from Ireland into W Scotland overnight into the 23rd, with lesser falls elsewhere across Scotland, Ireland and in some Cent and E areas of England. Some of the heavy falls in Scotland were thundery. The day dawned misty across much of England - and during the morning further heavy, thundery rain fell across parts of Yorkshire. An elderly man has been rescued from his home on Barra after it flooded in heavy rain shortly after midnight. In another incident, a family had to be rescued from a campervan after a river burst its banks on Skye. Drivers faced hazardous road conditions in North and West Yorkshire when up to 40 mm of rain fell in one hour during heavy downpours. The flash flooding resulted in dozens of emergency call-outs, submerged roads and caused delays on rail journeys between York and Manchester. In Scarborough, drains overflowed and the fire service had 50 firefighters handling incidents throughout the town. West Yorkshire Fire and Rescue Service said it received 23 flood-related calls between 0800 and 1000 GMT, with sandbags used to protect homes on Parker Road in Dewsbury. The call-outs included three people stuck in vehicles and a lightning strike damaging a property in Wetherby. Flash flooding also brought morning rush-hour misery to commuters in Dundee. Motorists encountered lengthy delays around the city during heavy rainfall. By late evening most areas had turned drier - although it was cloudy with some rain across N Scotland (due to a wave depression, centre 1007 mb at 2400 GMT) near Wick) and in some parts of W Scotland and Ireland. Following a mild night across much of England, temperatures reached 20C as far N as Altnaharra but were close to the average for the time of year over most of England and Wales due to rather cloudy skies. However, it was quite warm in some E areas of England. (Weybourne 25.6C, Lerwick 13.5C maximum, Baltasound 8.7C minimum, South Uist 63.2 mm, Dublin Airport 9.0 h.)

The 24th was a day of sunny periods and widespread cloud across the British Isles. During the day a depression pushed towards W Scotland, driving fronts ahead of it across N Ireland and W Scotland that led to rain here, and in NW England, during the latter half of the day. A few showers fell in other areas of England and Wales, while it was a dull day on Shetland due to a slow-moving front here. (Wisley 22.3C, Lerwick 12.5C maximum, Braemar 5.6C minimum, Lerwick 25.0 mm, Jersey Airport 10.9 h.)

The 25th dawned cool across inland areas of England, following a night when areas of rain had moved E'wards across much of Scotland - but been slow-moving over N Ireland. Mist and fog patches affected parts of Wales and W England at dawn - these soon cleared and most of England and Wales had a dry day. The rain was slow to leave Northern Ireland and fell in places at times throughout the day across Scotland and parts of N England - gradually moving away to the E, despite a weak low remaining close to W Scotland (slowly filling and centred at 1012 mb to the W of Tiree at 2400 GMT). It was a sunny day across parts of E England and in East Anglia and in SE and Cent S England. (Monks Wood 24.6C, Fair Isle 14.2C maximum, South Newington 5.5C minimum, Helens Bay 29.2 mm, Shoeburyness 12.9 h.)

Despite a weak area of high pressure becoming established across the British Isles on the 26th, the day was a rather cloudy one in many areas due to the presence of weak fronts that moved over many coastal areas. Parts of S Ireland and S England had a misty start to the day before it turned warm across SE England and East Anglia. Overnight rain affected N Ireland, S, Cent and E Scotland - with falls during the day gradually becoming confined to E Scotland. (Frittenden 26.3C, Fair Isle 14.2C maximum, Katesbridge 5.8C minimum, Aviemore 7.2 mm, Aberporth 11.8 h.)

While high pressure continued to influence the weather across England and Wales on the 27th, giving a warm and dry day here after a misty start in places, a series of fronts spread across Ireland and W Scotland as the day developed leading to some light rain and rather cloudy skies here. Places in the London area reached 26-27C during the afternoon. (Kew Gardens 27.0C, Harris Quidnish 14.2C maximum, Rostherne 6.3C minimum, Harris Quidnish 5.4 mm, Camborne 12.9 h.)

Bank holiday Monday, the 28th, saw temperatures rising widely above 25C over E and S England, leading to many places reporting their highest temperatures for this bank holiday Monday (which has been held in late August in England and Wales since 1965). There was a misty start to the day across many parts of England, Wales and S Ireland, with overnight rain across N Scotland and lesser falls elsewhere at times in Scotland. At Valentia the overnight minimum temperature was 15.2C but - following the passage of a cold front that gradually swept SE'wards across Scotland and Ireland during the day - the daytime maximum was just 16.4C. The cold front led to rain spreading SE'wards across Scotland and Ireland during the day, with falls over N Wales and N England at 2400 GMT. (St Helier 29.2C, Fair Isle 15.3 maximum, Swyddffynnon 7.6C minimum, Achnagart 21.2 mm, Tibenham Airfield 12.6 h.)

On the 29th there were showery outbreaks overnight across Scotland and N England - during the day only the SE corner of England remained largely dry - after a misty start across many parts of the Midlands and SE England. In the SE corner of England there were a few heavy showers during the afternoon and early evening. The southeast was warm, locally very warm after a mild night when minimum temperatures remained above 17C in parts of Kent and on Jersey. (Frittenden 29.3C, Blencathra 12.6C maximum, Braemar 4.5C minimum, Achnagart 9.8 mm, Lerwick 11.1 h.)

Overnight into the 30th there was rain across NW Scotland and Ireland, and a second area of rain affected parts of Cent, S and E England and S Wales. The latter area was slow-moving during the day, leading to a cold and set day here with daytime temperatures being widely over 10 degC colder in SE England than just 24 hours earlier; this is a remarkably large fall for the time of year. Further N the weather tended to be more showery in nature, with much of Scotland, Ireland and Wales having sunny periods. (Helens Bay 19.7C, Chertsey Abbey Mead 12.6C maximum, Aboyne 1.6C minimum, Culdrose 16.8 mm, Ronaldsway 10.5 h.)

By dawn on the 31st there were some fog and mist patches across S England, while overnight across Ireland and in some W areas of the UK there were showers. The showers became more widespread during the day with thunder in some parts of England and Wales. In between the showers there were sunny spells in Ireland, England, Wales and S Scotland - although N Scotland remained rather cloudy. (Hull East Park 21.0C, Baltasound 13.0C maximum, Eskdalemuir 2.4C minimum, Myerscough 28.2 mm, St Athan 10.4 h.)

British Isles weather, September 2017

Winds were light on the 1st due to high pressure, leading to some mist and fog patches across S and Cent England by dawn. There was some light rain overnight across parts of Scotland in particular, while during the day most places had spells of sunshine, especially across S areas of the UK and Ireland. There were some heavy, thundery showers - notably overnight in the Channel Islands, from late morning to mid-afternoon in places from East Sussex to Suffolk, and later in the day from North Yorkshire to East Anglia; these latter storms were very active in places close to the Thames Estuary in the evening. (St James Park 22.0C, Fair Isle 13.8C maximum, Sennybridge 1.2C minimum, Waddington 13.8 mm, Bude 12.5 h.)

After overnight thundery outbreaks in the SE had cleared early on the 2nd, much of Britain had a dry and sunny day although mist and fog patches were widespread across S Scotland, England, Wales and Ireland by dawn. Frontal cloud spread rain (heavy in some areas) into Ireland from late morning onwards, the rain later moving into N Ireland and SW England in the evening. 26 mm of rain fell at Valentia in the 12 hours ending 1800 GMT. (Charlwood 22.1C, Lerwick 13.8C maximum, Braemar 0.1C minimum, Writtle 12.4 mm, Kinloss 11.5 h.)

Areas of rain, heavy in a few places, spread steadily E'wards across the British Isles on the 3rd. Places close to the North Sea coasts had some early morning sunshine ahead of the frontal cloud, while W Ireland had some sunny intervals later in the day as the rain turned showery, leaving some mist parches in places here. People were trapped in vehicles and roads were closed as surface water flooding hit parts of Cornwall. Overnight rainfall caused water to reach depths of 4 feet in some places, and a flood alert was issued by the Environment Agency, who said the main areas of concern were the rivers Camel, Allen and Bodmin Town Leat. (Derrylin Cornahoule 21.2C, Lake Vyrnwy 12.2C maximum, Kielder Castle 2.8C minimum, Plymouth 48.4 mm, Kirkwall 7.9 h.)

Slow-moving fronts led to a rather cloudy day on the 4th, except across NW Scotland as a band of rain cleared from here. The cloud gave a generally mild night in all areas with overnight minimum temperatures around 16C across much of inland Ireland and over S Wales and SW England. These warm and damp conditions led to patches of mist and fog across the S half of the British Isles around dawn. It was warm during the day in places - particularly in the Midlands. (Wellesbourne 23.8C, Lerwick 13.3C maximum, Fylingdales 11.1C minimum, Baltasound 26.8 mm, Tiree 5.9 h.)

Bands of frontal rain spread SE'wards across the British Isles on the 5th - following a warm night across England and Wales where overnight minimum temperatures were widely in the range 15-17C. Falls were small across Scotland, and both here and across Ireland there were sunny periods following the clearance of the rain. (Hereford 21.9C, Blencathra 13.9C maximum, Braemar 5.5C minimum, Capel Curig 42.0 mm, Cork Airport 8.8 h.)

The 6th was a generally cloudy day across N Ireland and SW Scotland - and with only a few sunny periods elsewhere. A W'ly surface flow brought rain showers from the W throughout the day, with more general rain at times across N Scotland. Temperatures rose only a few degrees in much of the cloudy area during the day.(Shoreham 19.9C, Blencathra 13.0C maximum, Aboyne 1.4C minimum, Resallach 7 mm, Leuchars 8.7 h.)

The 7th was a generally cloudy day across Ireland, Scotland, Wales and in N and SW England. An area of low pressure moved towards NW Scotland during the day (MSL pressure close to 992 mb at 2400 GMT at Stornoway), pushing an area of rain across Scotland and Ireland in particular, with lesser amounts falling elsewhere. (Santon Downham 20.1C, Dalwhinnie 12.3C maximum, South Newington 6.6C minimum, Spadeadam 21.6 mm, Shoeburyness 5.9 h.)

The low pressure centres crossed N Scotland during the 8th, and was centred at 989 mb to the E of Aberdeen by 2400 GMT. Cloudy skies led to a mild night everywhere and rain moved SE'wards across much of England and Wales early in the day, only clearing from the SE after midday. Showers followed the rain from the W - these were thundery in places in the Midlands and East Anglia and also in parts of Cent S England. (Usk No.2 19.9C, Altnahinch Filters 12.1C maximum, Balmoral 6.2C minimum, Tibenham Airfield 44.4 mm, Aberdaron 7.9 h.)

A NW'ly flow bright showery weather to most areas during the 9th. Many of these showers were heavy with some thunder reported from Cent S England, SE England and East Anglia in the afternoon and evening. A weak ridge of high pressure gradually built from the W and the showers faded from this direction. (Dunstaffnage 20.3C, Okehampton 13.4C maximum, Santon Downham 5.7C minimum, Rochdale 25.4 mm, Prestwick 9.1 h.)

An E'ward moving low pushed fronts across all areas on the 10th, the low being centred at 974 mb to the E of Orkney by 2400 GMT. Early fog in the SE soon cleared ahead of rain and drizzle from the W. It turned brighter following the rain - which affected all areas at sometime during the day - and the best of the sunshine behind the rain was to be found in W parts of Ireland. Showers also followed the rain and theses were thundery in places in parts of N England and N Wales. (Manston 18.7C, Lerwick 12.1C maximum, Benson 4.6C minimum, Tyndrum 30.2 mm, Cork Airport 6.0 h.)

Low pressure remained close to NE Scotland during the 11th, leading to a blustery day in all areas, although the winds gradually eased during the day as a NW'ly set in. Showers were widespread during the day - with some thunderstorms reported in East Anglia, London and Kent. The Northern Isles and NE Scotland were rather dull - with longer spells of frontal rain. (Shoeburyness 20.4C, Dalwhinnie 11.8C maximum, Fyvie Castle 5.1C minimum, Capel Curig 41.2 mm, Cork Airport 9.2 h.)

The 12th began with showers overnight, especially over Scotland, Ireland and W England - falling in a NW'ly flow. These moved E'wards during the day although many E areas remained largely dry. During the afternoon a deepening depression (storm Aileen) crossed S Ireland and by 2400 GMT was centred over NW Lancashire (centre 982 mb). As a result it turned windy in S areas - and an area of rain spread rapidly E'wards on the S flank of the low. (Heathrow 19.6C, Dalwhinnie 11.9C maximum, Katesbridge 4.5C minimum, West Freugh 26.0 mm, Shoeburyness 9.6 h.)

Storm Aileen moved quickly away E'wards across N England early on the 13th. Overnight rain cleared S areas overnight but became slow-moving over Cent Scotland, before drifting slowly SE'wards over E Scotland and later NE England. Elsewhere the early rain gave way to showers. After a windy start across England and Wales, wind speeds gradually eased as a showery NW'ly flow developed from the W. Much of mainland Scotland had a dull day - elsewhere sunny spells were widespread between the showers. Commuters have faced rush hour disruption after Storm Aileen brought strong winds to parts of the UK, the storm affecting rail services and leaving thousands without power overnight. Gusts included one of 74 mph at Mumbles Head. Highways England warned drivers of lorries, caravans and motorbikes of an increased risk of being blown over. On its website, National Rail said falling trees and large branches, power cuts and debris blown onto the tracks were causing problems. Affected services include Greater Anglia, London Midland, Southern and Thameslink. Other services were affected earlier, during the morning rush hour. At its height, the storm cut power to 60,000 homes in Wales - some for 10 minutes, others for several hours. In Nottinghamshire, more than 800 homes experienced power cuts overnight, and in Lincolnshire, 700 homes lost power. (Manston 19.6C, Balmoral 11.0C maximum, Killylane 5.1C minimum, Bainbridge 38.2 mm, Lyneham 9.7 h.)

A showery from from the NW affected all areas on the 14th, with pressure slowly rise from the SW to 1020mb in SW Ireland by late evening. The showers were widespread but most areas had spells of sunshine in between the showers - although NW Scotland remained rather cloudy while S Ireland was quite sunny. (Shoeburyness 18.8C, Dalwhinnie 10.5C maximum, Tyndrum 4.0C minimum, Fyvie Castle 27.8 mm, Cork Airport 11.0 h.)

The showery NW'ly flow continued on the 15th. A cool night in parts of Cent and S England was followed by a rather cloudier day than before, due partly to a large area of heavy showers that moved S'wards across Wales and SW England at first and later due to some heavy showers in S England with hail and thunder in places. Larger areas of showers merged to give more general spells of rain in other areas during the day. (Frittenden 17.8C, Loch Glascarnoch 10.2C maximum, Santon Downham 2.8C minimum, Cardinham 28.6 mm, Manston 8.5 h.)

It was a cool night in many inland areas into the 16th as a mainly N'ly flow persisted for much of the day. Rain moved S'wards in some W areas of the British Isles - with further showers, thundery in places, in E parts of the UK. It was a rather dull day across Ireland, and generally cloudy in most other areas. (Usk No.2 17.9C, Killylane 9.2C maximum, Benson 3.0C minimum, Aberporth 30.6 mm, Morecambe 6.3 h.)

High pressure on the 17th led to mainly light winds and some early fog by dawn. Further showers followed during the day, primarily in E areas of the UK and in N Wales and N England. Thunder was reported in parts of Cent and E England - with Ireland, SW Scotland, W Wales and SW England having a sunny day. It was rather dull across NE Scotland and the Northern Isles. (Coton-In-The-Elms 18.4C, Balmoral 11.9C maximum, Tyndrum -0.9C minimum, Scampton 30.2 mm, Magilligan 11.4 h.)

High pressure again led to mainly light winds on the 18th. Parts of N and Cent Scotland had an early ground frost while showers fell in many areas in the E of the UK overnight. The best of the sunshine was to be found across Ireland during the day, while an area of rain moved SW'wards over N Scotland giving a dull day here. Longer spells of rain also affected N, Cent and E England later in the day, with some thunder in S England. Later in the evening cloud and a few spots of rain moved E'wards in W Ireland.(Wiggonholt 18.5C, Carterhouse 10.3C maximum, Castlederg 0.3C minimum, Writtle 17.6 mm, Casement Aerodrome 10.0 h.)

Ground frost was widespread across Cent Scotland and N England early on the 19th under an area of high pressure - with a few places having a slight air frost. Showers in the E and SE soon cleared away and a ddry, sunny day then followed in many areas. The exception to this was W and Cent Ireland - where some frontal rain lingered on and off for much of the day, and then became a little more widespread later in the evening. (Mumbles Head 18.8C, Fair Isle 12.8C maximum, Braemar -0.8C minimum, Cromer 10.6 mm, Leuchars 10.8 h.)

Frontal rain spread across much of Ireland and into W and Cent areas of Scotland by dawn on the 20th. Further E there was some mist and fog in parts of S and E England by dawn. The latter soon cleared while by the evening the rain had affected most of Ireland, Scotland, Wales and the W half of England. Most of Ireland and Scotland remained dull during the day, while only on the Channel Islands was more than 4 h of bright sunshine recorded. (Guernsey Airport 20.2C, Castlederg 12.4C maximum, Santon Downham 3.0C minimum, Logan Botanic Garden 25.6 mm, Jersey Airport 6.6 h.)

A S'ly flow ahead of a cold front gave a mild day at first in many E areas of England on the 21st. By dawn the area remained largely dry but a cold front pushed E'wards across here later in the day. Much of Ireland and w Scotland turned sunny in the morning as rain cleared from here - and this sunshine then spread E'wards, although some W parts had some showers following the front. (Shoeburyness 20.1C, Kinloss 11.0C, Castlederg 4.7C, Whitechurch 24.2 mm, Aldergrove 9.6 h.)

by dawn on the 22nd much of the E half of England had mist and fog patches, while another area of rain had spread E'wards across much of Ireland - with some falls also in W Scotland. At Belmullet 23 mm of rain fell in the 12 hours ending 0600 GMT. Parts of Cent Scotland and inland areas in the E half of England had a slight ground frost before dawn. During the day the rain moved to affect much of W Scotland, N England and Wales with a little rain further to the southeast in the evening. (Gravesend 19.2C, Dalwhinnie 10.6C maximum, Altnaharra -1.2C minimum, Harris Quidnish 20.0 mm, Shoeburyness 11.4 h.)

The 23rd was sunny in areas close to the England Channel and rather dull across much of Ireland. There was some fog in parts of S Scotland and N England by dawn while further rain fell during the day, mainly light, in some W areas but especially across Ireland later. Sunny skies over S England extended slowly into Wales and the Midlands and it was warm in these sunny areas. (Pershore College 20.7C, Fair Isle 13.3C maximum, Katesbridge 3.0C minimum, Okehampton 2.8 mm, Jersey Airport 9.6 h.)

Much of England and Ireland had mist or fog patches by dawn, while overnight into the 24th there had been outbreaks of rain across Ireland and in some W parts of the UK. These spread E'wards during the day - although most of England remained dry, sunny and warm. As the rain moved E'wards skies brightened up mover Ireland - in the Channel Islands it was dull with the rain leading to misty conditions. (Northolt 22.8C, Dalwhinnie 12.7C maximum, South Newington 5.2C minimum, Dundrennan 15.4 mm, Shoeburyness 9.3 h.)

A front remained slow-moving on the 25th across parts of England and Scotland. To the W a cool night was followed by a sunny, largely dry day - especially over Ireland. Elsewhere a cloudy but mild night saw outbreaks of rain, heavy in places, with further falls (that diminished as the day wore on) and cloudy skies during the day. (Mumbles Head 20.5C, Braemar 12.6C maximum, Katesbridge 1.3C minimum, Northampton Moulton Park 26.2 mm, Dublin Airport 10.6 h.)

The rain-bearing front continued to weaken during the 26th. Except in W areas of Ireland and Scotland early mist and fog was widespread, following a generally mild and dry night in most areas. The front gave almost no rainfall during the day - but cloud cover remained widespread. A few coastal districts in the east and northeast stayed foggy all day; otherwise, across much of England it was a mild day. (Hampton Water Works 22.2C, Inverbervie 13.1C maximum, Altnaharra 4.0C minimum, Charsfield 6.4 mm, Camborne 10.6 h.)

Mist, fog and haze was widespread across S Scotland, England and Wales by dawn on the 27th. Overnight rain had been widespread, and heavy in places, in W Ireland. 38 mm of rain fell at Valentia in the 12 hours ending 0600 GMT. The rain area moved E'wards during the day, with only a few parts of NE Scotland remaining dry by late evening. It was a warm day ahead of the rain - while few places away from N Scotland and the North Sea coasts saw much sunshine. (Gravesend 21.9C, Dalwhinnie 12.5C maximum, Santon Downham 5.9C minimum, Derrylin Cornahoule 35.0 mm, Altnaharra 4.4.h.)

Frontal rain cleared much of E Britain during the morning of the 28th - which dawned after a very mild night in SE England - but the rain lingered during the day across the Northern Isles. Parts of Ireland, Wales and Cent England had mist and fog forming before dawn but once these and the rain had cleared a day with sunny spells followed. During the afternoon further frontal rain spread across Ireland and into W Scotland, while another area of rain edged into SW England. (Santon Downham 21.1C, Lough Fea 12.2C maximum, Derrylin Cornahoule 6.0C minimum, Coningsby 15.0 mm, Shobdon 8.5 h.)

A deep low moving N'wards to the W of Ireland on the 29th pushed outbreaks of frontal rain across all areas during the day - following a mild night in parts if Cent S England and the Channel Islands. Behind the rain (falls of which were mostly light or moderate) showers and sunny spells followed. Some thunder was observed in parts of Ireland and SW Scotland, and it was a mild day in SE England with 20C reached in places. (Gravesend 20.6C, Tulloch Bridge 13.2C maximum, Redesdale Camp 7.4C minimum, Achnagart 15.4 mm, Ronaldsway 9.7 h.)

Most areas saw some rain at times during the 30th - these being heavy for a time in the morning in Cumbria and parts of N Wales. It was a cloudy day across Wales and SW England - elsewhere the precipitation was interspersed with sunny intervals at times. However, the best of the sunshine tended to be found across Scotland with rain spells lingering longer in the S. (Holbeach 18.4C, Dalwhinnie 11.3C maximum, Redesdale Camp 2.6C minimum, Shap 40.6 mm, Dyce 9.7 h.)

British Isles weather, October 2017

Ground frost was widespread overnight into the 1st in E and Cent areas of mainland Scotland - with a slight air frost in places. Elsewhere, rain and drizzle was widespread overnight. During the day rain was again widespread, with some heavy falls across Scotland. The rain, frontal in nature, gradually cleared from the W to be followed by showers. The sunniest areas tended to be in NE Scotland, ahead of the rain, while the SW'ly flow led to temperatures that were mostly above normal. It turned windy later in the day in NW areas as pressure fell ahead of an approaching depression. (Hereford 20.5C, Lerwick 12.8C maximum, Braemar -1.8C minimum, Achnagart 28.8 mm, Kinloss 3.7 h.)

Low pressure centred to the N of Scotland led to a windy day on the 2nd across N Britain in particular. The associated NW'ly flow led to heavy showers in many N areas with falls of rain across S areas of Britain, especially later in the day. The best of the sunshine was to be found over Ireland, N England and S Scotland; N Scotland and Wales were generally dull throughout the day. Winds gusting up to 70 mph caused traffic disruption across Scotland. The Dornoch Bridge and the Tay Road Bridge were closed to high sided vehicles and high wind warnings were in put in place on the Skye, Clackmannanshire and Erskine bridges. The Forth Road Bridge was closed to cyclists and pedestrians. A number of ferries were cancelled, including CalMac services from Oban to Castlebay, Coll and Tiree. Northlink Ferries also warned of some disruption and a number of cancellations to Pentland Firth sailings. The high winds also caused the flagpole at Edinburgh Castle to snap. (Frittenden 19.0C, Tulloch Bridge 10.9C maximum, Aviemore 7.2C minimum, Cluanie Inn 52.6 mm, Boulmer 10.2 h.)

Pressure built from the SW during the 3rd, reaching almost 1028 mb in the Channel Islands and SW England by 2400 GMT. Overnight rain and showers affected parts of Ireland, and W and N areas of Scotland. These falls eased off during the day although it later clouded over from the NW, and there was rain in the evening in western and northern Scotland. Across S England it was a largely sunny day. (Heathrow 17.3C, Dalwhinnie 9.7C maximum, Benson 5.4C minimum, Resallach 17.4 mm, Guernsey Airport 9.5 h.)

A cold front crossed S'wards over Scotland early on the 4th, developing a low centre along it over N England later in the day. Rain and showers affected Scotland and N Ireland at first overnight, later spreading to Cent Ireland, N and Cent England during the day. It turned brighter across N Scotland and remained dry and bright across S England and the Channel Islands. Elsewhere, the day was rather dull. (Exeter Airport 17.2C, Salsburgh 9.8C maximum, Kinbrace 4.9C minimum, Cassley 30.0 mm, Guernsey Airport 8.4 h.)

An area of rain moved SE'wards overnight and into the morning on the 5th, giving some heavy falls over N England and N Wales. Showers followed from the N as a NW'ly surface flow developed but these were largely confined to Scotland and N parts of England, Wales and Ireland. Once the rain had passed, England, Wales and S Ireland had a largely sunny day as pressure reached 1029 mb over S Ireland in the evening. (St James Park 18.0C, Loch Glascarnoch 9.3C maximum, Carterhouse 3.3C minimum, Rochdale 29.0 mm, Leeming 10.0 h.)

Clear skies early on the 6th led to a ground frost over parts of Ireland, Scotland and N England in particular. A few coastal areas of Scotland had some showers overnight. By midday frontal rain had reached W parts of Ireland and Scotland and this spread to all areas N of a line The Wash-N Devon by late evening. Ahead of the cloud and rain it was a sunny day - especially in S and SE England. (Usk No.2 17.4C, Lerwick 8.8C maximum, Katesbridge -0.1C minimum, Achnagart 5.6 mm, Shoeburyness 9.7 h.)

The 7th was a rather cloudy day with spells of frontal rain affecting all areas at times. In many areas falls were mostly light and it was quite mild in some E and S areas, but cooler towards the N and W. (Exeter Airport 19.0C, Lerwick 9.9C maximum, Shoreham 4.9C minimum, Cluanie Inn 21.6 mm, Charterhall 5.1 h.)

There was some fog in parts of SW England by dawn on the 8th, following a night when some light rain fell across Ireland and W Scotland, and also elsewhere in parts of England and Wales. The day was largely dry - but with some further light falls of rain across Ireland and W Scotland - and in a few other areas. Except in parts of SW and Cent S England it was a rather cloudy day - but was quite mild in some S areas of England. (Hurn 19.3C, Lerwick 10.4C maximum, Lerwick 4.1C minimum, Giants Causeway 5.0 mm, Exeter Airport 8.1 h.)

The 9th was a largely cloudy day due to areas of frontal cloud that gave spells of rain to most areas at times during the day. Falls were generally slight although another frontal system brought an area of heavier rain into W Scotland in the evening. It was again a mostly mild day. (Writtle 18.1C, Spadeadam 11.4C maximum, Frittenden 5.3C minimum, Achnagart 10.0 mm, Aberporth 3.9 h.)

The 10th was a cloudy day in many areas. Overnight rain affected most places, but was most widespread across Scotland, Ireland and later N England. Some light rain and drizzle affected England and Wales during the day - but the heaviest falls were again to be found over W Scotland and in parts of Ireland. It was a mild day for the time of year due to a surface flow from the SW. (Hereford 19.4C, Dalwhinnie 10.3C maximum, Drumnadrochit 4.9C minimum, Achnagart 30.8 mm, Shobdon 4.8 h.)

Low pressure centred to the N of Scotland led to a blustery day with outbreaks of frontal rain on the 11th. Falls were heavy over N Wales, Cumbria and S Scotland. Although it remained dull across England and Wales, clearing rain led to the developed of showery conditions with sunny spells across Ireland and Scotland. Ahead of the showers it was a warm day in E and Cent England. At Honister 130 mm of rain fell in the 24 hours ending 0900 GMT. Some parts of Cumbria saw more than 200 mm of rain fall in less than 24 hours, according to provisional figures from the Environment Agency. Honister, Seathwaite and Ennerdale were the worst hit areas as torrential downpours closed schools and disrupted road and rail travel. The Borrowdale area was also badly affected, with two bridges forced to close. Northern Rail said lines were blocked due to floods between Carlisle and Maryport causing major disruption. Egremont Bridge in Egremont and Forge Bridge in Eskdale were both closed. (Weybourne 18.5C, Resallach 11.2C maximum, Stornoway 8.6C minimum, Capel Curig 69.0 mm, Lerwick 5.4 h.)

Scotland and Ireland were largely cloudy on the 12th, but there were sunny spells in much of Wales and the S half of England. Overnight rain was mainly confined to Scotland, while during the day a warm sector pushed NE'wards across Ireland, SW England and Wales - giving outbreaks of rainfall here. It turned misty under the warm sector in the evening, with some fog patches in parts of S England. (Kew Gardens 18.3C, Dalwhinnie 10.7C maximum, Aboyne 2.7C minimum, Achnagart 13.8 mm, Exeter Airport 7.6 h.)

Wales and the S half of England remained under a warm sector on the 13th, leading to a relatively mild day here. Across Ireland minimum temperatures overnight were widely around 15-16C, with 21C reached in parts of England later. The Channel Islands and northeast Scotland were generally sunny during the day, but elsewhere it was cloudy with some early mist and fog patches in S England. A slow-moving cold front led to some heavy rainfall over N Wales and also in Cumbria for a while. (Cranwell 21.5C, Resallach 14.0C maximum, Frittenden 6.3C minimum, Capel Curig 77.0 mm, Jersey Airport 6.6 h.)

The 14th dawned after a mild night across the British Isles; from N England S'wards overnight minimum temperatures were in the range 14-17C at most places, with minima above 15C widely at inland locations. Overnight minima to 0600 GMT included 17.3C at Linton-on-Ouse, 17.0C at Rostherne and Hawarden, and 16.8C at Shawbury. Parts of S Ireland and S England dawned misty, with rain and drizzle falling in places across Ireland, Wales and N England. During the day patchy rain affected mainly W and N Scotland, Cent Ireland and parts of N England. It turned misty again in the evening across much of S England, following a day when temperatures were mostly above normal. (Hull East Park 22.3C, Dalwhinnie 11.2C maximum, Fyvie Castle 4.7C minimum, Capel Curig 36.0 mm, Guernsey Airport 8.8 h.)

Patchy fog and low cloud affected parts of Ireland and Cent, S and E England at first on the 15th following another mild night across the British Isles. Rain fell before dawn in N and W Scotland, and across NW and W Ireland. In many places the mist lingered all day, thickening again in the evening across much of England and Wales. SE England had the best of the sunshine during the day - with most other areas remaining rather cloudy. Rain fell in N and W areas while a thundery shower moved across Cornwall in the late evening. (Charsfield 20.7C, Carterhouse 13.0C maximum, Chertsey Abbey Mead 7.2C minimum, Harris Quidnish 26.0 mm, Shoeburyness 9.3 h.)

The 16th followed another mild night in many areas. During the day ex-hurricane Ophelia moved N'wards to SW Ireland (centre 969 mb here by 1200 GMT) and then to the Western Isles by 2400 GMT. Rain and gales spread across W and later N areas, especially across Ireland. There was some thunder reported later in the day across the Northern Isles. Gusts of 80-90mph were recorded around Irish Sea coasts. Temperatures were again on the mild side during the day, but cooler across N Scotland. Much of England and Wales was dry during the day following some early rain that moved N'wards. Smoke from Iberian forest fires was said to be responsible for a reddish-looking sun that was seen in parts of S and Cent England during the day in a very mild warm sector. All schools across Ireland were due to the anticipated effects of ex-Hurricane Ophelia. Thousands of homes and businesses in Ireland lost power, after severe winds caused disruption and damage. Flights and ferries were cancelled, and many roads are still closed due to fallen trees. The Republic of Ireland was worst hit - three people were killed and restoring the electricity supply to 245,000 customers was expected to take days. Many businesses shut early to ensure staff made it home before the worst of the storm hit, turning many city centres into ghost towns. The south-west coast is thought to have suffered the brunt of the damage, with Cork one of the worst-hit areas. A number of flights to UK airports were forced to land or divert following reports of "smoke smells" - much of the polluted air seemed to be confined to a small vertical depth in places, thus helping to concentrate the side-effects. Precautionary landings were reported from flights travelling to and from Dublin, Manchester, Liverpool and Jersey. During the height of the storm in the evening in SW Scotland, high winds saw roofs being blown off buildings in Castle Douglas and Dumfries. Scaffolding was also brought down in Kirkcudbright and dozens of trees were blown down. (Manston 23.5C, Lentran 10.9C maximum, Stornoway 5.3C minimum, Dunstaffnage 19.4 mm, Camborne 6.6 h.)

On the 17th heavy rain and gales in Scotland slowly eased as the low system moved away to the NE of Scotland. After a dry and sunny start to the day across much of England and Wales, it clouded over and an area of rain spread from SW England towards the E Midlands and East Anglia by late evening. It turned misty and foggy across Ireland in the evening once the rain had cleared from here and much of Scotland also turned dry eventually. A tenement building in Glasgow partially collapsed as the remnants of Hurricane Ophelia brought high winds to parts of Scotland. Firefighters were called to the unoccupied building in Albert Road, Crosshill, at about 0300 GMT after reports of debris falling into the street. Across Scotland, trees were blown down, blocking roads and causing disruption to some rail services; motorists were urged to take extra care during Tuesday's morning rush hour. High wind warnings were in place on the Erskine, Clackmannanshire, Tay and Friarton bridges and on the new Queensferry Crossing. Ferry sailings between Cairnryan and Northern Ireland were subject to "major disruption" due to the weather, said P&O Ferries. Meanwhile, ScotRail said the line at Markinch had been blocked after a freight train hit a fallen tree, causing severe disruption to services throughout Fife. (Pershore College 17.6C, Lerwick 9.7C maximum, Okehampton 5.6C minimum, Cluanie Inn 42.2 mm, Leconfield 8.0 h.)

Ireland and parts of England dawned foggy on the 18th, while rain in the S half of England was slow to clear towards the E during the day. Much of England and Wales remained dull during the day, while it was a cool day in the brighter areas further N. In the evening heavy rain fell in parts of N England, with mist and fog patches reforming again across much of England and Wales in the evening. (Herstmonceux 18.5C, Braemar 8.7C maximum, Capel Curig -0.4C minimum, Woburn 19.6 mm, Dundrennan 5.6 h.)

The 19th was a dull day almost everywhere. Extensive low cloud, with areas of fog affected many areas of England and Wales at first, with outbreaks of rain across much of the country associated with a shallow low over SW Britain. These continued through the day with some heavy bursts. The heaviest falls were generally across Ireland - 42 mm fell at Gurteen in the 12 hours ending 1800 GMT. Many eastern and southern districts were quite warm. (Manston 19.2C, Lake Vyrnwy 11.1C maximum, Aviemore 4.4C minimum, Killowen 31.6 mm, Kinloss 1.2 h.)

Outbreaks of rain and showers were widespread overnight into the 20th but these steadily migrated E'wards along with the driving low. The day was much drier with some sunshine, though mostly a lot of cloud. Further rain spread from the SW from late afternoon onwards, reaching all but NE Scotland by late evening. (Strathallan 17.4C, Pennerley 10.1C maximum, Castlederg 4.7C minimum, Lough Fea 23.4 mm, Guernsey Airport 6.7 h.)

A deep low, named storm Brian, affected the British Isles on the 21st. Centred to the W of Ireland, 964 mb, at 0000 GMT, it moved to just S of the Isle of Man by 1200 GMT (centre 978 mb) and then off E Scotland (986 mb) by 2400 GMT. Showers and longer spells of rain were widespread as the associated fronts crossed the British Isles - although it was relatively drier across N and Cent Scotland. It was windy over Ireland, England and Wales, with gales or severe gales around some windward coasts: there were gusts of up to 75 mph around Welsh coasts with 78 mph winds recorded at Aberdaron and at Capel Curig. Limerick was among a number of Irish cities hit by flash flooding as the River Shannon overflowed its banks. Dozens of trains were cancelled and ferries were affected also. Newport and Caerphilly were worst areas affected by power loss. The M4's Briton Ferry Bridge - between junction 41 and junction 42 - in Neath Port Talbot and the M48 Severn Bridge in Monmouthshire were closed due to high winds, but reopened late on Saturday evening. The A477 Cleddau Bridge in Pembrokeshire was closed while the A55 Britannia Bridge between Anglesey and the mainland was closed to high-sided vehicles. Dozens of Arriva Trains Wales services were cancelled around Wales and there were widespread delays on the network as temporary speed restrictions were in place on the majority of railway routes. (Santon Downham 16.4C, Okehampton 10.1C maximum, Lentran 7.4C minimum, Capel Curig 48.4 mm, Shoeburyness 6.0 h.)

The 22nd was cloudy and showery as the British Isles lay in a brisk surface flow from the W and NW. The extreme E of England remained relatively dry - and there were some sunny spells here. Another series of fronts crossed Ireland later in the day, bringing rain that spread across Ireland and into SW England, W areas of Wales and SW Scotland before midnight. (Strathallan 15.0C, Bingley 8.9C maximum, Okehampton 5.5C minimum, Cluanie Inn 22.2 mm, Charlwood 6.7 h.)

Frontal rain spread across all areas on the 23rd although amounts in E England were slight, while falls were heavy over the Northern Isles at times. The day was generally a cloudy one, although NW Ireland and W Scotland had some sunny spells. Parts of England and Wales turned misty in the evening. (Exeter Airport 19.0C, Baltasound 11.2C maximum, Balmoral 1.9C minimum, Lerwick 20.2 mm, Stornoway 4.6 h.)

The 24th was a cloudy day across much or Ireland, England and Wales - following a mild night in places close to the English Channel. Rain and drizzle affected all areas - although E England had only slight rainfall after a misty start in places. Much of Cent and E England was quite warm. (Hereford 19.9C, Lerwick 11.0C maximum, Balmoral 3.1C minimum, Achnagart 46.6 mm, Tiree 4.2 h.)

Minimum temperatures overnight into the 25th across S England were 14-15C in places. After some overnight rain, and blustery winds over England and Wales, most places had sunny spells. W and N Scotland became increasingly blustery and showery. The Channel Islands were misty, and these conditions spread across much of S England by midnight. (Wisley 19.6C, Cluanie Inn 11.0C maximum, Aboyne 4.6C minimum, Cluanie Inn 36.6 mm, Wittering 7.7 h.)

The 26th was a day with a NW'ly surface flow and rising pressure, rising to 1032 mb by 2400 mb in W Ireland. A slow-moving front lay across S areas - warm air to the S and cooler conditions to the N. It was a rather misty day across England and Wales (except in N England) with light rain and drizzle falling from the front in the S. Further N it was rather cloudy with some sunny intervals - along with showers across N Scotland. It turned drier in most areas in the evening. (Jersey Airport 17.8C, Loch Glascarnoch 9.1C maximum, South Newington 2.6C minimum, Resallach 17.4 mm, Dyce 6.7 h.)

There was mist and fog in places by dawn on the 27th across many areas of England, Wales and Ireland. Away from S England and N Scotland, there was patchy ground frost in many inland areas. An area of high pressure slipped S'wards during the day (centred at 1037 mb over SE Ireland at 1200 GMT) giving most areas a mostly dry and sunny day - although some rain and drizzle pushed S'wards into the Northern Isles in the evening. Mist and fog patches formed over many parts of Ireland, SW and Cent England in the evening. (Plymouth 17.6C, Spadeadam 9.1C maximum, Kielder Castle -0.7C minimum, Resallach 1.0 mm, Leeming 9.2 h.)

There was a slight air frost in some parts of Cent S England into the 28th, which dawned with mist or fog in parts of Ireland, Wales, England and SW Scotland. England, except in the N and SW, had sunny spells during the day. Elsewhere the day was cloudy and it turned cold and windy in the N as a N'ly flow developed behind S'ward-moving fronts that brought some rain with them. (Nantwich 17.4C, Lerwick 9.7C maximum, Hurn -0.6C minimum, Cluanie Inn 13.0 mm, Filton 6.0 h.)

The patchy frontal rain cleared S'wards during the morning of the 29th and, except for a few areas along the S coast of England, a day with spells of sunshine followed. Showers continued to fall near some E coasts and it continued to turn colder from the N during the day; some sleet fell on Shetland. (Usk No.2 16.3C, Braemar 6.3C maximum, Kinbrace 3.1C minimum, Swyddffynnon 7.8 mm, Dundrennan 8.1 h.)

Many inland areas of England, Scotland and Wales had an air frost at first on the 30th after a night when a few showers continued to fall in North Sea coastal areas. Although pressure remained general high, fronts spread across Ireland and Scotland during the day, with rain falling across N England and Wales by the evening. It was a sunny day in most areas of England ahead of this cloud and rain, and it was a cold day in the cloudier, N areas. (Isles of Scilly 14.5C, Aboyne 4.9C maximum, Tulloch Bridge -5.0C minimum, Fylingdales 4.2 mm, Exeter Airport 8.8 h.)

There was a ground frost in parts of S England at first on the 31st, but the day was then rather overcast nearly everywhere. Spells of rain or drizzle fell across N and Cent areas - but S parts of England remained mainly dry. Daytime temperatures were generally higher across Scotland (reaching 15C in many mainland areas of N Scotland) than over England and Wales. (Drumnadrochit 16.6C, Okehampton 10.6C maximum, Hurn 0.1C minimum, Achnagart 23.8 mm, Camborne 2.3 h.)

British Isles weather, November 2017

High pressure dominated conditions in S areas on the 1st, while N areas lay under a series of S'ward-moving fronts. There was some fog (and a little ground frost) before dawn in S England with mist in Cent and some N parts of England, while over parts of Ireland and Scotland overnight minimum temperatures remained above 12C in places. Outbreaks of rain and drizzle overnight over Scotland edged only slowly S during the day - into parts of N England and N Ireland by the evening. Fog reformed in many areas of England during the evening. (Aboyne 16.2C, Fylingdales 10.0C maximum, Hurn 2.0C minimum, Gt Cumbrae Millport 26.0 mm, Exeter Airport 5.3 h.)

Mist and fog across Cent, S and E England cleared during the morning of the 2nd but persisted in a few locations for much of the day. There was a slight air frost in a few sheltered areas of Cent and S England - although the day then turned generally mild everywhere. The day was generally cloudy, however, due to slow-moving fronts that gave only slight falls of rain and drizzle. Much of mainland Scotland, along with many areas of S England, avoided the cloudy skies and had a sunny day. (Chivenor 16.8C, Lentran 7.8C maximum, Shobdon -0.4C minimum, Fyvie Castle 2.6 mm, Dundrennan 7.9 h.)

Mist and fog was widespread at dawn across Cent, S and E England on the 3rd - the mist then lingered during the day across S England with some fog patches remaining until the afternoon. Many parts of Scotland, NW England and S England had a slight ground frost. Patchy rain affected N Scotland and W Ireland and more general rain later spread E'wards here. A low over W France pushed frontal rain N'wards into S England in the evening - behind another area of rain that affected the N Midlands in the evening. (Gravesend and Plymouth 15.9C, Spadeadam 6.7C maximum, Aboyne -4.7C minimum, Dunstaffnage 11.4 mm, Dyce 4.4 h.)

Rainfall was widespread overnight across the British Isles into the 4th - especially across Wales and parts of S England. During the day the frontal rain areas tended to clear away to the E, being followed by more showery outbreaks. These showers included falls of hail and some hill snow in W and N areas of Scotland. E and SE England remained generally cloudy during the day; elsewhere sunny spells were widespread between the showers. (Shoreham 14.7C, Loch Glascarnoch 6.6C maximum, Drumnadrochit 0.6C minimum, Hurn 36.6 mm, Kinloss 7.3 h.)

Many inland areas of the UK had a ground frost on the 5th while showery rain affected Ireland and W Scotland overnight. Precipitation declined during the day as a ridge of high pressure built from the S - MSL pressure reached 1026 mb on the Channel Islands in the evening. Some snow fell across N Scotland and the Northern Isles, while there were sunny spells in most areas. (St Helier 12.4C, Lerwick 5.0C maximum, Aboyne -2.9C minimum, Portglenone 15.4 mm, Morecambe 8.3 h.)

Air frost was widespread over much of England, Wales and Scotland into the 6th, while much of E and Cent England had mist of fog patches before dawn. Much of England and east Wales was then sunny, but it became increasingly cloudy from the W as frontal rain spread across Ireland and Scotland, and then into the W half of England later in the evening. The sunniest areas were in E and Cent England, ahead of the advancing frontal cloud. (Plymouth 14.0C, Fylingdales 6.2C maximum, Braemar -6.0C minimum, Harris Quidnish 25.2 mm, Manston and Shoeburyness 8.3 h.)

Frontal rain moved slowly E'wards on the 7th, with showery weather and sunny spells following from the W. The rain intensity decreased as the front reached the SE corner of England while skies cleared in places in the W in the evening as pressure rose here - to 1024 mb in SW Ireland by 2400 GMT. (Isle of Portland 13.9C, Carterhouse 6.0C maximum, Frittenden -0.6C minimum, Whitechurch 26.4 mm, Cork Airport 7.3 h.)

Frontal rain cleared SE England during the morning of the 8th - with most inland areas of the British Isles (except for places in E England) having a widespread ground frost before dawn. Areas in and around Wales, in NE England and E Scotland and E Ireland had an air frost. By midday rain had spread from the W across W and N areas of Ireland, and across W Scotland, and the rain spread across N England, Wales an SW England by midnight. It was a cloudy day across W areas of Scotland and Ireland, and in parts of East Anglia and SE England. (Achnagart 13.5C, Spadeadam 6.2C maximum, Braemar -5.5C minimum, Kinlochewe 19.0 mm, Wellesbourne 7.9 h.)

Parts of East Anglia and SE England had an air frost into the 9th; elsewhere it was cloudier overnight with some rain across Scotland and Ireland in particular. Parts of E and S Scotland in were fairly sunny during the day, while heavy rain moved SE'wards across Ireland and Scotland in the evening, with winds increasing in strength across N parts of the British Isles during the day. A lifeboat battled mountainous seas to go to the rescue of a stricken fishing vessel; it took more than nine hours for Thurso lifeboat to reach the boat, which was drifting towards the shore near Whiten Head, and tow it back to the safety of Scrabster harbour. The lifeboat crew were hampered by gale force winds, squalls of hail, sleet and rain and waves of up to 10 metres in height. (Pershore College 15.8C, Loch Glascarnoch 7.1C maximum, Benson -3.0C minimum, Cassley 36.2 mm, Charterhall 5.0 h.)

Patchy rain moved SE'wards overnight and at first on the 10th, followed by sunny spells in most districts away from W and N Scotland. Showers fell in many areas during the day but as a wave depression moved towards W Ireland (centre 1011 mb close to Belmullet) further rain spread across Ireland and Wales and then into England. It was mild in the S, while some snow fell over high ground in Scotland. (Shoreham 14.4C, Dalwhinnie 3.5C maximum, Dalwhinnie 1.0C minimum, Cluanie Inn 22.6 mm, Tibenham Airfield 7.1 h.)

Cloudy skies overnight into the 11th led to a mild night with outbreaks of rain across much of Ireland, Wales and England, while further N there was an air frost in many parts of Scotland. In S Ireland overnight minimum temperatures exceeded 13C in places. It remained mostly dull, damp and in places misty in this wet areas, with further spells of rain or drizzle with another wave depression forming later in the day close to the English Channel. Across Scotland there were sunny spells and showers, which turned wintry in NE Scotland. Brighter conditions gradually spread into N England and East Anglia during the day. (Swanage and Thorney Island 14.9 C, Dalwhinnie 3.6C maximum, Kielder Castle -1.8 C minimum, Okehampton 38.2 mm, Dyce 5.6 h.)

A N'ly flow became established on the 12th around an area of high pressure to the SW of Ireland (MSL pressure close to 1030 mb in SW Ireland at 2400 GMT). The rain in S Britain gradually cleared away during the morning; many inland areas of Scotland had an air frost overnight before showers developed along N/NW-facing coasts. Some of these were wintry in N and E Scotland and it was a cold day across Scotland generally. Most places had spells of sunshine at times during the day. (St Helier 11.4C, Dalwhinnie 3.2C maximum, Kielder Castle -2.4C minimum, Cardinham 16.8 mm, Morecambe 8.1 h.)

The N'ly flow present at first on the 13th turned W'ly as fronts spread across Scotland and Ireland during the day. Coastal showers continued overnight in the E and a widespread inland air frost developed before dawn across the British Isles. E and S England had early sunshine before cloud spread from the NW - with rain spreading into Ireland and Scotland during the morning. Ahead of the rain there was some snow in places in Scotland and N England. Much of E England remained dry during the day - it was cold here while daytime temperatures eventually rose across W Scotland and W Ireland in particular. (Achnagart 12.6C, Leek 4.2C maximum, Benson -4.9C minimum, Resallach 17.4 mm, Guernsey Airport 7.5 h.)

Slow-moving fronts led to a rather cloudy day on the 14th. There was a widespread ground frost in East Anglia at first; most places had some light rain at times and it turned widely misty across E and N England in the evening. The best of the sunshine was to be found in parts of E Scotland, E England and the NE Midlands. (Topcliffe 14.4C, Dalwhinnie 7.2C maximum, Santon Downham -1.4C minimum, Gogerddan 16.4 mm, Morpeth Cockle Park 3.7 h.)

Fronts across S areas on the 15th led to a rather dull day here. In fact, only in parts of the Northern Isles and E Scotland did the sun break through for more than an hour. After some early mist and fog patches in E England, S britrain was dull, mild but with some rain and drizzle. Much of Scotland had a widespread ground frost and a colder day followed here with a few showers in the N and W. (Swanage 15.2C, Redesdale Camp 4.5C maximum, Redesdale Camp -2.6C minimum, Harris Quidnish 5.6 mm, Dyce 3.0 h.)

A cold front pushed SE'wards over the British Isles on the 16th, with high pressure developing to the rear of it. MSL pressure rose to close to 1031 mb in SW Ireland by 2400 GMT. There was widespread mist and some fog in E and Cent England by dawn before overnight rain in Ireland and Scotland spread E'wards. Showers followed the front, with some snow then falling in the cold air over high ground in Scotland. Most places away from East Anglia and the SE corner of England had some sunshine behind the front. It turned windy across Shetland during the day. (Hurn 15.1C, Loch Glascarnoch 4.9C maximum, Loch Glascarnoch 1.7C minimum, Kinlochewe 32.0 mm, Leuchars 6.7 h.)

High pressure into the 17th led to a widespread ground frost - with an air frost in many parts of England, Wales and E Ireland. N Ireland, W and N Scotland had some rain and showers overnight - this rain spread into N England and S Ireland during the day. Away from England it was, consequently, a rather cloudy day with some showers in N areas leading to snow over high ground and a few rumbles of thunder in N Scotland. (St Helier 13.1C, Llysdinam 4.7C maximum, Benson -4.5C minimum, Kinlochewe 24.0 mm, Camborne 8.3 h.)

High pressure in the S at first on the 18th gave way to a cold, NW'ly flow during the day. After air frost early in the night in parts of S England it turned cloudy from the N. Overnight rain in Scotland and Ireland then spread S'wards, lingering in SW England by late evening. As a result, Wales and the S half of England and Ireland were largely cloudy. Across Scotland there were showers and periods of sunshine - the showers fell as snow in the N and over high ground. (Usk No.2 13.5C, Dalwhinnie 4.1C maximum, Frittenden -2.7C minimum, Trawsgoed 22.6 mm, Dyce 6.1 h.)

There was a widespread ground frost early on the 19th away from SW England and S and W parts of Ireland. W Scotland and much of Ireland then had a dull day as frontal systems brought rain here from the W with some snow over N hills in the evening. Much of England and E Scotland ad a brighter day - but by midnight rain was widespread over much of Wales and N England. (Isles of Scilly 13.7C, Spadeadam 1.7C maximum, Shap -4.8C minimum, Thomastown 5.8 mm, Tibenham Airfield 7.5 h.)

Rain spread overnight to most areas and the 20th was then a generally cloudy day with spells of rain and drizzle - and some snow over high ground in Scotland. These damp conditions led to mist and fog patches in places although precipitation amounts were small in many areas. Most of Scotland was cold while milder conditions tended to prevail across S areas of Britain and Ireland with 13-14C being reached widely. (Nantwich 16.6C, Balmoral 1.2C maximum, Baltasound -0.5C minimum, Gt Cumbrae Millport 24.8 mm, Hawarden 1.8 h.)

The 21st was a cloudy day except as fronts pushed N'wards at first introducing milder air, then edged E'wards across N Scotland - as a low centre moved across the country. MSL pressure fell to 981 mb to the E of Orkney by 2400 GMT. Away from the N half of Scotland it was mild for some of the day with spells of rain - after a mild N in S areas. Cent and N Scotland was cold and wet, with snow over the mountains. (Bude 15.1C, Balmoral 3.8C maximum, Baltasound -0.6C minimum, Cassley 32.6 mm, Shoeburyness 1.0 h.)

On the 22nd much of Scotland and N Ireland was cold and wet, with snow on some of the higher ground. However, northwest and mainland N Scotland only had a little rain, and there was sunshine in the Outer Hebrides. Over England, Wales and S Ireland it was mild and windy, but cloudy except in SE England and S parts of East Anglia. There were some falls of heavy rain over N Wales along the English-Scottish border - and flooding resulted in places. Up to 1,000 people in Mountmellick, Co Laois were affected by heavy floods after three rivers burst their banks due to heavy rain. Earlier this evening, two housing estates were evacuated by emergency services and more than 100 homes have been significantly damaged by the floods. Hundreds of residents from the town are staying in hotels in Portlaoise. Schools and several roads in Cumbria were closed because of flooding caused by heavy rain. The A5087 Ulverston coast road was closed and Cumbria County Council was urging people to avoid travelling unless necessary. A number of roads on the Isle of Man were left "impassable" after heavy rain caused widespread flooding as well as a landslip. The main road at Glen Helen was closed after a river burst its banks and a road in Lower Foxdale was also sealed off following a landslip. In Lancashire emergency crews received more than 500 calls, with Lancaster and Galgate the worst affected places. Roads were shut and rail services suspended by floods in north Wales. Lancaster University's weather station said it has recorded its highest ever rainfall total. In the 24 hours from 0900 GMT today the station at Hazelrigg said 73.6 mm of rain had fallen - the highest level in more than 50 years. Rail users in Carnforth, Lancashire, had to take evasive action when the station flooded. Five hundred properties mainly in Blackpool, Thornton-Cleveleys and Poulton on the Fylde coast, lost power due to the weather, Electricity North West confirmed. (Hawarden 16.5C, Loch Glascarnoch 2.6C maximum, Loch Glascarnoch 1.1C minimum, Capel Curig 83.6 mm, St Helier 6.4 h.)

Snow fell widely across N Scotland on the 23rd, spreading into S Scotland and N England later in the day. After a very mild but windy night with outbreaks of rain, much of southern Britain was sunny with temperatures above normal. There were a few showers in the west, and outbreaks of rain affected parts of S England, especially near the south coast, in the evening. Most areas saw some sunny spells at times during the day, most notably Cent, S and E England. (Manston 13.8C, Balmoral 1.0C maximum, Loch Glascarnoch -2.8C minimum, Spadeadam 24.8 mm, Yeovilton 6.6 h.)

N Ireland and Scotland had a cold day on the 24th with snow falling over N and Cent Scotland, and with falls also over high ground in Wales, N Ireland and N England. Elsewhere , many places were sunny although in parts of SE England the day remained dull. Showers fell close to the English Channel at times, while many W areas had showery outbreaks that included falls of hail in places. (Isles of Scilly 11.3C, Salsburgh 0.3C maximum, Katesbridge -4.9C minimum, Cassley 13.0 mm, Nottingham 7.4 h.)

Air frost was widespread away from extreme W areas of Ireland and Scotland into the 25th as an area of high pressure built from the W. A generally cold day followed with showers in the N and W; snow and hail were widespread, and there was isolated thunder, especially early in the day. It was a dull day across N and Cent Scotland - but there were sunny periods in most other areas. It was also quite windy in the N and W. Early in the day icy conditions caused train delays of up to 90 minutes, after temperatures dropped below freezing in many parts of the country overnight. Network Rail said some Southern, Gatwick Express and Thameslink lines were forced to run at reduced speeds. South Western Railway also warned of delays due to ice, which came on top of planned weekend engineering works. (St Helier 9.6C, Killylane 1.4C maximum, Topcliffe -6.3C minimum, West Freugh 29.4 mm, Brize Norton 6.9 h.)
