Regional Forecast for Wales

Headline:

Hot and sunny

Today:

The whole country will have a dry and hot day with plenty of sunshine. That low cloud which hung around Cardigan bay and Anglesey yesterday is not likely to be repeated so warm sunshine will dominate even on the coast. Maximum temperature 26 °C.

Tonight:

It will stay dry overnight with very little cloud but it will stay very mild everywhere in spite of this. Minimum temperature 12 °C.

Friday:

Friday will be dry, sunny and hot again everywhere. The sunshine may become a bit hazy later in the day as very high cloud spreads in from the west. Maximum temperature 27 °C.

Outlook for Saturday to Monday:

Heavy, thundery showers in the south will spread northwards during the morning. Sunday and Monday will be less hot with sunny spells and perhaps further rain in the south.

Updated: 01:53 on Thu 25 May 2017 BST

UK forecast for the next 5 days

Headline:

Hot and sunny

Today:

The UK will have another dry day with plenty of sunshine. It will become very warm or hot in most places, though less warm than yesterday near southern and eastern coasts. Only Shetland is likely to have any significant cloud.

Tonight:

There will be very little cloud overnight, even over the Scottish islands, but it will stay very mild everywhere in spite of this.

Friday:

Friday will be dry, sunny and hot again almost everywhere. It will cloud over in western parts of Northern Ireland later with the possibility of showery rain there later.

Outlook for Saturday to Monday:

Hot and mainly sunny weather breaking down as rain and thunderstorms move across the country from the west. Becoming fresher but still warm, although further chance of thundery rain later.

Updated: 01:51 on Thu 25 May 2017 BST

Outlook for the UK over the next 6-30 days

UK Outlook for Monday 29 May 2017 to Wednesday 7 Jun 2017:

A very uncertain period, but the more likely scenario is for rather mixed conditions on Bank Holiday Monday and Tuesday, with showery outbreaks of rain, perhaps heavy and thundery, drifting in from the south, but also some brighter spells. Temperatures are likely to be down in comparison to the weekend, although it could stay rather warm and humid, especially in the southeast. Meanwhile, it will probably be cooler and fresher in the north and west, where we may see windier conditions. From Wednesday onwards, we will generally see a mixture of sunshine and showers, particularly across the northwest. However, we may hold on to drier, brighter and perhaps warmer conditions in the far southeast, although some thundery showers are possible.

UK Outlook for Thursday 8 Jun 2017 to Thursday 22 Jun 2017:

Confidence is currently low through this period, though we are more likely to see changeable conditions continue through the early part of June. More settled weather may begin to dominate for a time towards the middle of June, bringing drier and brighter weather for many. Temperatures are likely to be close to normal at first, but may become generally warm, perhaps locally very warm for a time during mid June. By the latter part of June, there is a possibility of more unsettled conditions developing, with spells of rain at times, and temperatures returning closer to average.
