Forecast summary

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

Regional forecast for Wales

A chilly, clear night. Mainly dry and sunny tomorrow.

This Evening and Tonight:

Mainly dry with lengthy clear spells overnight and just a few showers likely, especially in the north and west. It will be a cold night for all, but the strength of the wind should prevent a frost for most places. Minimum Temperature 3C.

Saturday:

Another largely dry and bright day with plenty of winter sunshine. An isolated shower remains possible, most likely in the north and west. The wind should ease a little later. Maximum Temperature 10C.

Outlook for Sunday to Tuesday:

Turning milder and windy again on Sunday, but becoming largely cloudy with outbreaks of rain or drizzle throughout the period. Colder, clearer conditions then spreading from the north later Tuesday.

UK forecast for the next 5 days

Wintry showers in the north. Dry with clear spells elsewhere.

This Evening and Tonight:

Blustery showers continuing in the north and locally in the west, snow and ice a risk in Scotland, especially high ground. Largely dry elsewhere with lengthy clear spells, though the strength of the wind will prevent a widespread frost.

Saturday:

Showers at first in the north and parts of the west, wintry over northern hills. However, most places becoming dry with long sunny spells. Winds slowly easing and feeling cold.

Outlook for Sunday to Tuesday:

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

Outlook for the UK over the next 6-30 days

UK Outlook for Wednesday 24 Dec 2014 to Friday 2 Jan 2015:

A band of cloud and rain is likely to be affecting many central parts of the UK at first on Christmas Eve, clearing the southeast later. Colder conditions then spreading to many areas, continuing into Christmas day, with some wintry showers across N areas. Probably becoming increasingly unsettled into the weekend, with the risk of persistent heavy rain, gales and also a risk of significant snow, this more likely across some northern parts. Conditions after Christmas likely to remain predominantly cold across the N, but with the chance of milder interludes across the far south. Otherwise the following week looks perhaps rather cold on the whole, with snow showers likely across many northern areas but milder, wetter interludes possible at times. Generally windy for many throughout.

UK Outlook for Saturday 3 Jan 2015 to Saturday 17 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 expected, particularly over the high ground.
