UK forecast for the next 5 days

Headline:

A foggy or frosty start. Rain moving southeast. Clearer later.

Today:

A frosty start for many with slow-clearing mist and fog in the southeast. Cloud and rain across the northwest will move southeastwards to all parts with mostly dry, sunny weather following behind. Strong winds across northern Scotland will ease.

Updated: 02:08 on Sun 17 Dec 2017 GMT

Outlook for the UK over the next 6-30 days

UK Outlook for Thursday 21 Dec 2017 to Saturday 30 Dec 2017:

In the run up to Christmas it is most probable that the UK should see temperatures return near to or above average for the time of year, with a north-south split developing. In northern parts of the UK the weather is likely to be changeable with strong winds and rain or showers; as well as drier, brighter interludes. Across the south of the UK it will be drier and more settled although probably rather cloudy. Any rain will only be a brief interruption and any breaks in the cloud cover could give foggy or frosty overnight conditions. Over the Christmas period the north-south split looks mostly likely to begin to break down with unsettled, often windy, conditions developing thereafter, with any snow most likely across the north of the UK.

UK Outlook for Sunday 31 Dec 2017 to Sunday 14 Jan 2018:

Through the final days of December, and perhaps the start of January, it is likely to be unsettled and often windy across much of the UK. Temperatures will be near to or below average and snow is likely, at times, especially across northern parts of the country. Through the first half of January a gradual reduction in the frequency of Atlantic westerlies seems most likely, this will be coupled with an increase in the frequency of colder and drier periods, although confidence is low at this stage. Milder, wetter, and windier spells should become more short-lived during this period with the colder and drier spells of weather bringing an increased likelihood of overnight frost and fog, as well as some snow, wintry showers, and below-average temperatures.
