Outlook for the UK over the next 6-30 days

UK Outlook for Tuesday 19 Dec 2017 to Thursday 28 Dec 2017:

In the run up to Christmas the UK should see temperatures return near to or above average for the time of year, with a north-south split developing by around the 21st Dec. In northern parts of the UK the weather is likely to be changeable with strong winds, rain or showers, at times; 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 will give foggy or frosty overnight conditions. Around Christmas Eve the north-south split should 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 Friday 29 Dec 2017 to Friday 12 Jan 2018:

Through the last days of December 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.
