Fine, dry and sunny across the rest of Britain this morning. Through the afternoon that heavier rain will lie across western Scotland and Northern Ireland. More cloud to be found in the west with central and eastern areas dry and sunny. Strong southerly winds will be blowing across western Britain with gusts to 65 mph across The Western Isles. maximum temperatures of 19 to 25 Celsius.

Dry with clear spells to the east of this. A warm, humid night to come with minimums of 13 to 20 Celsius.
