Sunday is off to a damp start in much of the north and there is patchy rain in the south too. Through the rest of the day it turns brighter in much of the north but heavy showers push into the west. In the southern half of the UK thicker cloud brings drizzle or light rain at times, but some sunny spells are likely.

Temperatures range from 12C (54F) in the north west to 22C (72F) in the south where the cloud breaks. See the rain and lightning radar for the latest view.

Cooler air pushing southeastwards 

Tuesday should be warm and dry in the south. Temperatures may push up towards 26C (78F) if sunny periods continue into the afternoon. An area of cloud and rain will be pushing southeastwards, but there is some uncertainty about timing. Cooler and showery conditions follow into northern areas.

By Wednesday the band of rain may become slow moving over southern counties. Central and northern regions have a bright day with scattered showers and sunny spells.
