Forecast Summary

  • Regional
  • UK 5 days
  • UK 6-30 days

Wales

Headline:

Chilly again today, but becoming milder into next week.

Today:

A bright and frosty start, with the risk of some icy patches. However cloud will soon spill in from the northwest, bringing a risk of showery rain to many parts from mid morning. Still on the chilly side for many. Maximum temperature 8 °C.

Tonight:

Showery rain will gradually peter out, though many parts will remain rather cloudy overnight. However the cloud cover will ensure a milder night with little if any frost. Minimum temperature 2 °C.

Sunday:

Most parts should start dry, with a few brighter spells in the east. Rain will then sweep across all parts during the day, accompanied by brisk winds, but milder conditions. Maximum temperature 11 °C.

Outlook for Monday to Wednesday:

Another chilly start to Monday, but then becoming more concertedly milder next week. Often rather cloudy, though some brightness is possible at times, especially to the east of high ground.

Updated: 01:23 on Sat 16 Dec 2017 GMT

UK forecast for the next 5 days

Headline:

A cold start to the weekend, but milder next week.

Today:

Most will be dry with sunny spells, after a frosty, locally icy start. A few wintry showers across northern Scotland and perhaps North Sea coasts at first. Showery rain will move from Northern Ireland in to Wales and western England.

Tonight:

Generally fairly cloudy across the west, with patchy rain and less cold than recent nights. Some frost again further to the east, and a risk of freezing fog by dawn.

Sunday:

Frost and fog will slowly lift, then dry and bright for a time. Occasionally heavy rain in the northwest will move southeast, along with milder, but windier conditions.

Outlook for Monday to Wednesday:

Turning milder for all parts, though with a good deal of cloud. Fog will likely affect western hills and perhaps develop overnight across parts of the south.

Updated: 01:23 on Sat 16 Dec 2017 GMT

Outlook for the UK over the next 6-30 days

UK Outlook for Wednesday 20 Dec 2017 to Friday 29 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 will 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 Saturday 30 Dec 2017 to Saturday 13 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.
