Further details
Developing showers and thunderstorms are likely to intensify across parts of the warning area through the evening, before easing away eastwards after midnight. Quite a lot of places will probably avoid the heaviest rain and thunder, but others could experience torrential downpours and frequent lightning, while large hail and strong wind gusts may also affect a few places. Central parts of southern England are perhaps most likely to see impacts. Rainfall amounts will be highly variable, as is usual in such situations, but the wettest spots perhaps seeing around 25 mm of rain inside an hour, and a possibility that somewhere could catch over 40 mm in 2 or 3 hours.
