British Isles weather, December 2016

There was a widespread air frost across England and E Wales into the 28th with mist or fog in many areas of England and E Wales. These were slow to clear and persisted all day in parts of Lincolnshire, East Anglia and the Midlands leading to a cold day in these areas. Under prevailing high pressure (MSL pressure exceeding 1040 mb across most of England and Wales at midday) it was a largely dry day - and sunny except in N and W Scotland and NW Ireland. (Trawsgoed 12.1C, Hawarden 0.8C maximum, Topcliffe -7.2C minimum, Harris Quidnish 2.0 mm, Jersey Airport 7.5 h.)

Air frost was widespread on the 29th across England, Wales and parts of E Ireland, with mist and fog across much of this area. Across Scotland overnight it was milder with some rain in the N - and further light rain fell here during the day. Across E and S parts of England a sunny day followed once the fog cleared - where this persisted it remained rather cold. Much of Scotland and Ireland was rather cloudy. (Achnagart 13.6C, Hereford -0.6C maximum, Pershore -7.0C minimum, Baltasound 1.2 mm, Shoeburyness 7.0 h.)

Much of England (except in the NW and SW) and Wales had a widespread inland air frost on the 30th and mist and fog was widespread across both countries. After a mild night in N Scotland (minimum temperatures 10-11C in places) a very mild day followed in Ireland, mainland Scotland, Wales and W areas of England. In many parts of England, especially in E areas, the fog persisted all day and around East Anglia maximum temperatures were closer to 2C. Frontal rain affected N Scotland at times during the day leading to some heavy falls in a few W parts. In most places it was a cloudy day. 38 mm of rain fell at Lusa in the 24 hours ending 2100 GMT. Seventeen people were injured early on Friday morning in the latest accident to occur amid dense fog across England and Wales in the final days of 2016. An Oxford Bus Company bus slid off the northbound M40 slip road near Thame at 0245 GMT; weather observations at Benson reported visibility down to 100 m at the time. (Kinloss 14.0C, Middle Wallop 1.4C maximum, South Newington -5.6C minimum, Kinlochewe 75.4 mm, Guernsey Airport 6.8 h.)

The 31st was a generally mild day across the British Isles in terms of daytime maximum temperatures - although a cold front spread S'wards across most of Ireland and Scotland by midnight, introducing colder air here. Cent, E and S parts of England had overnight fog which cleared in most places but thickened again in the evening. The day was a generally cloudy one with showers behind the cold front turning wintry later across N Scotland. By 2400 GMT the temperature at Dyce had dropped to 3.4C. The cold front brought a spell of heavy rain as it passed - 52.6 mm fell in the 24 hours ending 2100 GMT at Loch Glascarnoch, most of it in the first 12 hours of this period. (Dyce 13.5C, Resallach 6.3C maximum, Goudhurst -2.2C minimum, Achnagart 96.8 mm, Jersey Airport 4.6 h.)
