Forecast summary

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

Regional forecast for Wales

Bright and breezy and feeling colder.

Today:

Early cloud in the south clearing, then bright and breezy with plenty of sunshine. The strong northwesterly wind making it feel much colder. Dry for most, but a few showers likely, especially towards the north and west, wintry over hills. Maximum Temperature 9C.

Tonight:

Lengthy clear spells overnight, just the odd shower likely, especially in the north and west. The strength of the wind should prevent a frost for most. Minimum Temperature 3C.

Saturday:

Another largely dry and bright day with lots more sunshine. Still an isolated shower is possible, most likely in the west. The wind should start to ease a little later. Maximum Temperature 9C.

Outlook for Sunday to Tuesday:

Turning milder again, but largely cloudy with outbreaks of rain or drizzle throughout the period. Colder and clearer conditions then spread from the north on Tuesday night.

Updated at: 0231 on Fri 19 Dec 2014

UK forecast for the next 5 days

Wintry showers in the north. Plenty of sunshine elsewhere.

Today:

Rain in the south soon clearing this morning. Blustery showers in the north, often heavy and locally wintry. A few showers for other western areas too. Otherwise, plenty of sunshine but feeling colder for all with a brisk northwesterly wind.

Tonight:

Remaining windy with further wintry showers in the north. Largely dry for central and southern areas with lengthy clear spells, though the strength of the wind preventing a widespread frost.

Saturday:

Blustery, wintry showers in the north gradually easing through the day. The strong northwesterly wind easing a little too. Otherwise largely dry with more winter sunshine, but feeling cold.

Outlook for Sunday to Tuesday:

Turning milder again, but largely cloudy with outbreaks of rain or drizzle at times. Colder and clearer conditions in the far north then spread southwards through Tuesday and Tuesday night.

Updated at: 0231 on Fri 19 Dec 2014

Outlook for the UK over the next 6-30 days

UK Outlook for Tuesday 23 Dec 2014 to Thursday 1 Jan 2015:

Rain over central and southern parts Tuesday should move slowing southeastwards, clearing the southeast early on Christmas Eve. Colder showery conditions to the north, with snow on high ground here, following over the entire UK. The colder conditions then persist for most through Christmas Day and the following weekend with snow even to low levels at times in the north. There is a low probability of some more persistent rain crossing southern parts during the holiday weekend with a risk of snow on the leading edge. Otherwise in the following week there looks to be a gradual return to spells of wet and milder weather interspersed with colder, showery conditions. Generally windy for many throughout the period with risk of gales, these mainly in the northwest.

UK Outlook for Friday 2 Jan 2015 to Friday 16 Jan 2015:

The most likely scenario for the coming New Year is for a continuation of changeable, and at times windy weather coming from the Atlantic with the wettest weather probably across western parts of the UK, and eastern parts most likely to see the best of any dry weather. In between the wetter periods there should be drier, brighter, and colder spells. Temperatures are most likely to be around or slightly below average for the time of year with overnight frosts and some snow over the high ground expected. There is a chance of some overnight and morning fog in places too. However, there is a low likelihood that the drier spells will become more prolonged between weather systems.
