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

Regional forecast for Wales

Tonight:

Remaining mild and windy with local coastal gales likely. Patchy rain will become increasingly persistent, and heavy at times, particularly over the hills in the north and west. Minimum Temperature 8C.

Monday:

Another mild, windy and cloudy day with patchy rain or drizzle for most. More persistent rain, possibly heavy at times, slowly edges southwards across the country, particularly in the west. Maximum Temperature 13C.

Updated at: 1212 on Sun 21 Dec 2014

UK forecast for the next 5 days

Windy with rain in north and west, largely fine elsewhere.

Cloudy with rain at times in the north and west, this heavy and persistent across western Scotland. Windy across northern parts, especially to the east of high ground. Elsewhere, largely fine and breezy. Feeling milder.

Rain and strong winds will gradually sink south into northern England and Wales. Colder, showery conditions returning to the north. Cloudy, breezy with rain at times in the far south.

Rain band, locally heavy, across central areas stalls. Mild, cloudy with patchy rain or drizzle to the south. Colder, clearer, showery conditions to the north, wintry over hills. Windy throughout.

Updated at: 0221 on Sun 21 Dec 2014

Outlook for the UK over the next 6-30 days

UK Outlook for Friday 26 Dec 2014 to Sunday 4 Jan 2015:

A cold and largely fine start to Boxing Day with a widespread frost likely. Remaining dry for most of the day, but unsettled conditions pushing eastwards later, with rain, perhaps transient hill snow, and strong winds developing, with a risk of gales, most likely in north and west. During the weekend, unsettled, slightly milder and windy conditions are most likely across the UK, with periods of rain or showers. Into the following week, more settled conditions may push into western parts, and outbreaks of rain and showers will then primarily affect northern and eastern areas, with snow possible to lower levels in the north. Thereafter, the most likely solution is for periods of frontal rain and milder temperatures, but also some good spells of dry weather, especially in the south.

UK Outlook for Monday 5 Jan 2015 to Monday 19 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 southern 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 possible, particularly over the high ground.
