Although many places will miss them, heavy showers and some thunderstorms are expected to develop this afternoon over some southern and eastern parts of England. Downpours could bring around 20 mm of rain within an hour, and perhaps 30-40 mm in a few hours for a few locations, leading to possible surface water flooding in places. Lightning and hail are most likely to occur across southeastern counties of England.
The showers and thunderstorms will ease by late evening. For further details see https://www.metoffice.gov.uk/weather/warnings-and-advice/uk-warnings
