After a cool start, it will be mostly dry with sunny spells across southern and eastern parts, with perhaps a few showers in the west. Rain across Northern Ireland will move into northern and some western parts through the day.
Rain, some heavy, will continue to move slowly southeast into Wales, the Midlands and northern England overnight. Some showers and clear spells for Scotland and Northern Ireland. Mostly dry elsewhere.
Cloud and rain will move slowly southeast across England and Wales, although the far southeast should stay dry until the evening. Brighter with scattered, heavy showers elsewhere. Feeling rather cool.
Outlook for Tuesday to Thursday:
Predominantly unsettled and often cloudy with showers or longer spells of rain, locally heavy and thundery, accompanied by strong winds at times. Becoming drier from the west later. Cool throughout.
