Outlook for the UK over the next 6-30 days

UK Outlook for Friday 22 Dec 2017 to Sunday 31 Dec 2017:

In the run up to Christmas it is most probable that the UK should see temperatures near to or above average for the time of year. On Friday it will probably start mainly fine and dry with bright spells for many. However, skies are likely to turn cloudier in the north and west with outbreaks of rain developing into Saturday. Into the Christmas period, timings remain uncertain, however rain and cloud should clear southeastwards, leaving drier, brighter and colder conditions for a time. Showers are likely for some, and these could turn wintry in the north. In the period between Christmas and New Year, very unsettled conditions look likely with gales at times, and perhaps showery conditions in the north and west.

UK Outlook for Monday 1 Jan 2018 to Monday 15 Jan 2018:

At the start of the new year, 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 confidence becomes very low, but longer periods of more settled weather may become established. This would lead to prolonged spells of drier and colder conditions, as well as an increased likelihood of overnight frost and fog. Any milder, wetter, and windier spells should become more short-lived during this period.
