Latest forecast for South East Wales

Today

Today will be another warm day, and it will be generally sunny, though this afternoon, some patchy cloud and well scattered showers will develop with a risk of some isolated thunder.

Tonight

Tonight, there looks to be variable cloud cover and clear spells in between. Largely dry, although the odd light shower can't be ruled out in places.

Friday

Tomorrow will turn noticeably cooler, and there will be areas of cloud for much of the day, along with a few sunny intervals in between, some hazy. Any early showers should clear too to leave it dry.

Staying cooler than of late into Saturday, with dry conditions, sunny spells, and a few patchy areas of cloud. Much cooler on Sunday, and it will remain dry with variable cloud and sunny breaks in between. Monday will be another dry and cool day, with a few sunny spells to start, but then turning largely cloudy for the rest of the day.
