Regional Forecast for Wales

Tonight:

Cloud, hill fog will gradually spread across far western areas. Central and eastern areas will be a little clearer and colder with some patchy fog possibly forming. Minimum temperature -1 °C.

Tuesday:

Tuesday will be milder and increasingly cloudy across all parts with patchy light rain or drizzle. Hill fog is also likely to persist over the high ground. Maximum temperature 11 °C.

UK forecast for the next 5 days

Headline:

Fog across England tomorrow, mainly dry and cloudy elsewhere

This Evening and Tonight:

Cold and frosty for much of England and Wales, away from the west, with fog and low cloud expected to become widespread. Cloudier, milder and windier in the north with some drizzle at times.

Tuesday:

Fog across England is likely to cause travel disruption at first, before it slowly begins to clear. Cloudy and milder elsewhere with strong winds and rain in the far northwest.

Outlook for Wednesday to Friday:

Turning drier, brighter and cooler in the north through Wednesday into Thursday. Cloudy and mild with patchy rain in the south. Cloud and patchy rain then spreading northeast on Friday.

Updated: 14:09 on Mon 18 Dec 2017 GMT

Outlook for the UK over the next 6-30 days

UK Outlook for Saturday 23 Dec 2017 to Monday 1 Jan 2018:

At the start of this period largely mild conditions are expected to dominate, as a band of rain, which may be heavy at times, moves slowly and erratically southeastwards. As this rain clears away brighter and colder conditions will move across the country and showers are likely, especially across the north and west. Some of these showers may be wintry, particularly over high ground, however in the south and east it will remain mostly dry. In the period between Christmas and New Year, very unsettled conditions look likely to develop with gales at times along with some heavy rain. Temperatures will fluctuate during this period between milder, wet and windy spells and colder but brighter, showery interludes.

UK Outlook for Tuesday 2 Jan 2018 to Tuesday 16 Jan 2018:

At the start of the new year, it is likely to be unsettled and often windy across much of the UK. Bands of rain are expected to move across the country with heavy, and perhaps wintry showers moving in behind. The best of any drier weather will be in southern and eastern parts. Through the first half of January confidence remain low, but longer periods of more settled weather may become established. This would lead to longer spells of drier and colder conditions, as well as an increased likelihood of overnight frost and fog.
