A very warm and sunny day for most places as high pressure stays in charge on Monday.

Most places will stay dry all day. A general easterly breeze, feeling fresh near coasts at 15 to 17C. High temperatures at 19 to 23C inland.

Showers ease overnight before a band of rain edges into the far northwest and north of Scotland through the wee hours. A cloudier night over the northern half of the British Isles with clearer skies to the south. Overnight lows of 11 to 13C under the cloud to the north, more widely 7 to 10C.
 

Tuesday
Most of England & Wales are dry with sunshine on Tuesday. Perhaps hazier in the north and west with high cloud.
