Forecast summary

Regional forecast for Wales

A frosty night for some tonight, then rather cloudy tomorrow.

This Evening and Tonight:

Any showers should gradually fade away this evening, leaving largely clear skies across Wales, before thicker cloud and patchy rain spreads into the north later. Under the clear skies in the south, a widespread frost will develop by dawn. Minimum Temperature -2 °C.

Thursday:

A bright but frosty start in the south, otherwise it will be a fairly cloudy day with some patchy rain. Skies may brighten up later though, especially in the north. Maximum Temperature 12 °C.

Outlook for Friday to Sunday:

Apart from the odd shower, Friday and Saturday should be largely dry with some sunshine and feeling less cold. Sunday then may see some rain move up from the south.

UK forecast for the next 5 days

Frosty in the south tonight, with patchy rain elsewhere.

This Evening and Tonight:

Showers across the south will die out this evening, leaving a dry, clear but frosty night, with odd fog patch also forming. Further north will be less cold, as cloud and patchy rain gradually moves southeastwards during the night.

Thursday:

Sunny but cold start in the south, but cloud and patchy rain further north will move across all areas during the day. Northern areas though turning drier and brighter later.

Outlook for Friday to Sunday:

Largely dry at first with some sunshine, feeling less cold. Through the weekend, winds will strengthen for all, with an increasing threat of rain or showers, especially towards the southwest.

Outlook for the UK over the next 6-30 days

UK Outlook for Monday 1 May 2017 to Wednesday 10 May 2017:

Bank Holiday Monday currently looks likely to be rather unsettled in the south, with some showery outbreaks of rain moving across the UK. However there will be brighter spells in-between, and in the brightness it should feel fairly pleasant, most likely in the north. There may well also be some showers on Tuesday, and to a much lesser extent on Wednesday, but on the whole Wednesday is likely to be dry with some sunshine for many. Temperatures early next week are expected to be around average for early May. Then from Thursday onwards we are likely to see high pressure dominate, with largely dry and settled weather prevailing, with increasing amounts of sunshine. The settled weather is also likely to bring temperatures slightly above average, especially during the sunnier interludes.

UK Outlook for Thursday 11 May 2017 to Thursday 25 May 2017:

Heading into the middle of May, and on balance the dry and settled weather is likely to continue to dominate. There may however be some occasional wetter interludes, with western areas more likely to see these. Temperatures are likely to remain above average, and possibly becoming very warm at times at first, before perhaps returning to nearer normal towards the end of the period.
