Overnight cloud breaking to sunshine on Thursday.
This Evening and Tonight:
A fine evening with some late sunshine. Cloud building from the east overnight though clear spells holding on further west, under which fog patches and a rural frost may form. Minimum Temperature 0C.
Thursday:
Any fog and low cloud clearing during the morning to leave a fine day with prolonged sunny skies. Warm inland with light winds, but a cooling breeze at the coasts. Maximum Temperature 17C.
Outlook for Friday to Sunday:
Plenty of warm sunshine on Friday after fog clears through the morning. More cloud around during the weekend with an increasing chance of showery rain. Cooler and windier by Sunday.
UK Outlook for Monday 14 Apr 2025 to Wednesday 23 Apr 2025:
A much more changeable period through at least the early part of next week as low pressure lies to the west of the UK bringing a mixture of showers and some longer spells of rain, but also some drier, sunnier interludes. There is a low risk of heavier, possibly thundery showers coming into the country from the south for a time early in the period, but confidence in this aspect of the forecast is low and these may well pass to the east. This heralds a wetter period through the middle of April with showers or longer spells of rain at times, which could be heavy and thundery in places. Strong winds could develop in some areas, particularly the south and west. Temperatures are likely to return closer to normal.
