British Isles weather, June 2020

Low pressure close to, or over, Ireland on the 27th (centre 993 mb near Malin Head at 1200 GMT) pushed a sequence of fronts across much of Ireland, Wales and England overnight and then over Scotland during the day. The rain tended to turn showery during the day and were rather sparse across parts of E England and N Scotland. Away from S Britain the showers turned thundery in laces. Much of the British Isles was generally rather cloudy except across parts of mainland N Scotland. As a result, the warmest conditions during the day occurred across parts of N Scotland. (Kinloss 26.5C, Capel Curig 14.6C maximum, Redesdale Camp 8.9C minimum, Sennybridge 24.0 mm, Stornoway 8.5 h.)

The 28th was generally chilly, blustery and showery, due to a slow-moving low centred just to the W of Scotland during the day. As a result, it was noticeably cold and wet over much of NW England, Ireland, SW and NW Scotland. Parts of S England and the Channel Islands had sunny spells. Honister Pass in the Lake District gave one of the wettest June days in the UK record for daily June rainfall - 212.8 mm of rain fell in the 24 hours from 0900 GMT; the heaviest known June fall in the UK was 243 mm at Bruton, Somerset on 28 June 1917. (Heathrow 22.0C, Blencathra 10.8C maximum, Okehampton 8.9C minimum, Kielder Castle 48.0 mm, Guernsey Airport 12.6 h.)

An area of low pressure pushed slowly E'wards across Scotland on the 29th, and numerous fronts associated with it meant that it continued chilly, blustery and showery, with further long outbreaks of rain overnight and at first over Scotland, N England, N Wales and the N half of Ireland in particular. There was some local thunder in the afternoon over E Scotland. The SE corner of England remained largely dry, although it was a cloudy day in all areas of the British Isles, with very few exceptions. (Heathrow 21.7C, Lake Vyrnwy 10.7C maximum, Dalwhinnie 8.4C minimum, Capel Curig 34.6 mm, Manston 8.7 h.)

While pressure rose slowly across Scotland on the 30th, by 1200 GMT another low centre was located close to Valentia, centred at 1003 mb. Fronts led to a day that was dull and cold, with widespread patchy rain and drizzle. There was widespread cloud, although it was brighter at times in isolated parts of SW and Cent Scotland. (Weybourne 21.9C, Ballypatrick Forest 13.1C maximum, Exeter Airport 9.5C, Ballypatrick Forest 9.8 mm, Tiree 10.5 h.)
