UK Outlook for Sunday 13 Apr 2025 to Tuesday 22 Apr 2025:
A transition from the fine and settled conditions most will have seen is expected through this period. This will most likely come in the form of a cold front progressing southeast bringing some rain and showers and fresher conditions. 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.
