Rain, some heavy, will pelt much of England Friday and Friday night as an unusually strong summer depression sweeps through the English Channel from the west.
Rainfall could be high enough for minor flooding, reaching about 50 mm in places.
Steady wetting rain will begin early in the day on the Cornwall Peninsula before overspreading South England, the southern Midlands and East England through the afternoon and evening on Friday. South Wales will share in the steadier, wetting rains beginning Friday morning.
Elsewhere in the United Kingdom, farther from the instigating depression, showery to rainy outbreaks will give relatively low rainfall on Friday across Scotland, North England and North Wales.
Early Saturday, steady rains will leave to the east of England, allowing brighter, drier weather to unfold over the United Kingdom.
Another strong depression will give bouts of wet weather on Sunday and Monday.
