Warning

Areas of showers and thunderstorms associated with a hot and humid air mass stranded across the southern half of the UK are expected to continue through Friday, with some continuing overnight into Saturday morning. Many areas encompassed by this warning will miss the thunderstorms altogether, but where they occur, heavy rain (20-30mm in an hour, and possibly as much as 50mm in 2 to 3 hours), frequent lightning, and in some places large hail are all potential hazards. The greatest chance of impactful showers is expected to be in the southern half of this warning area, where afternoon showers are more likely to be slow moving and prolonged.

Further heavy showers and thunderstorms are expected at times and may lead to some flooding or travel disruption
