Regional Forecast for Wales

Headline:

Turning cloudy with some rain tonight. Sunny and dry tomorrow.

This Evening and Tonight:

A predominantly dry night with clear skies, bar a few showers in the Bristol Channel and in the far north. Winds will turn light and temperatures will fall readily leading to a widespread frost away from towns and coastal areas. Minimum temperature -1 °C.

Friday:

A cold and frosty start across Wales with plenty of sunshine and light winds. A few showers in the north are possible. Another cold night with some heavy, wintry showers. Maximum temperature 8 °C.

Outlook for Saturday to Monday:

Staying cold for the weekend with frosty mornings and sunshine and wintry showers; showers of snow over high ground. Rain overnight into Monday, with showers and strengthening winds later.

Updated: 16:43 on Thu 23 Nov 2017 GMT

UK forecast for the next 5 days

Headline:

Cold with wintry showers in the north, largely dry elsewhere.

This Evening and Tonight:

Scattered showers continuing in the north, wintry on high ground and to low levels in Scotland. Some rain in the far south of England, but dry, cold and clear elsewhere.

Friday:

A frosty start in the north then a chilly day with showers in the northwest, with some snow falling on hills. Dry with sunshine across much of England and Wales.

Outlook for Saturday to Monday:

A cold weekend with frosty starts. Bright with wintry showers during the day, with snow perhaps settling on high ground. Windy, with risk of gales in north. Unsettled on Monday.

Updated: 15:08 on Thu 23 Nov 2017 GMT

Outlook for the UK over the next 6-30 days

UK Outlook for Tuesday 28 Nov 2017 to Thursday 7 Dec 2017:

A cold and frosty start for both Tuesday and Wednesday, then a mixture of sunshine and showers, these wintry at times with snow over northern hills, and with possibly spells of more persistent rain for some eastern areas. It will be windy too with a risk of gales in the north and east, and this will make it feel particularly cold. These cold and showery conditions look likely to continue into the weekend, with the showers most frequent and wintry in the north and east, with drier, sunnier weather elsewhere. Thereafter slow moving weather patterns continue to be the more likely scenario into early December, with some periods of rain at times, especially in the west, and with temperatures probably near to or slightly below the average.

UK Outlook for Friday 8 Dec 2017 to Friday 22 Dec 2017:

During this period of December, weather patterns are likely to continue to be fairly slow moving and this brings more uncertainty than normal into the forecast. It is probable that there will be some spells of wet, windy and at times mild weather with the wettest weather probably across western and perhaps some southern parts of the country. These may be interspersed with some drier and brighter spells too, when it could become colder with the risk of frost overnight. On the whole, temperatures may be a little colder than normal. Later in the month, it may become more generally unsettled and milder.
