Regional Forecast for Wales

Headline:

Rather cloudy and humid, but turning fresher later this week.

Today:

Tonight:

Staying mostly dry and on the mild side. Cloud will thicken through the small hours of Wednesday morning, however, and will give some patches of drizzle, especially over the hills. Minimum temperature 16 °C.

Wednesday:

A rather cloudy morning with patchy drizzle, but some brighter spells too. More persistent rain arriving for the afternoon will clear later with fresher, clearer conditions following from the northwest. Maximum temperature 23 °C.

Updated: 02:26 on Tue 21 Aug 2018 BST

UK forecast for the next 5 days

Headline:

Warm and humid for many; turning fresher later this week.

Today:

A rather cloudy start for many with some drizzly outbreaks here and there. Most places will brighten up into the afternoon with some warm and sunny spells developing across England and Wales. Turning breezier in the northwest.

Tonight:

A mild and dry night across much of the UK, especially the southeast. Some drizzly outbreaks lingering across western and southwest parts. Becoming wet and windy in the northwest.

Wednesday:

A band of rain will move southeastwards across the UK on Wednesday, reaching southeast England for the evening. The rain will be heaviest in the northwest. Fresher conditions will follow.

Outlook for Thursday to Saturday:

Fresher, brighter weather on Thursday and Friday, with sunshine and blustery showers. Showers heaviest in north and east. Saturday, early rain in south will clear. Sunnier weather elsewhere will follow.

Updated: 01:49 on Tue 21 Aug 2018 BST

Outlook for the UK over the next 6-30 days

UK Outlook for Saturday 25 Aug 2018 to Monday 3 Sep 2018:

This weekend,, many places will have sunshine and showers. These showers will be heavy at times, with a risk of hail and thunder particularly in the north, with sunnier spells in the southeast. It will be windy at times, and some more persistent rain may arrive from the west later on Sunday. For Bank Holiday Monday, it is most likely to be unsettled in the northwest, with longer spells of rain and some strong winds. Drier and brighter conditions are generally likely in the south and east. This northwest, southeast split is then quite likely to continue. Temperatures will start rather cool, but they will recover to around the seasonal average, with perhaps warmer conditions at times in the southeast. Drier weather may become more widely established into early September.

UK Outlook for Tuesday 4 Sep 2018 to Tuesday 18 Sep 2018:

For the start of September it looks likely that the weather pattern will only change slowly. Areas of high pressure and associated settled weather will probably increasingly dominate, with some longer dry spells, particularly for northwestern areas compared to much of August. However there are also likely to be some more changeable weather at times in the north and northwest, with outbreaks of rain and strong winds, with these conditions perhaps extending southeastwards at times. Temperatures by day are likely to be generally warmer than average, especially for the southeastern half of the UK but generally nearer the seasonal average further northwest, and there will be an increasing chance of chillier nights anywhere, as would be expected going further into September.
