Showers to end the day across the south-west, Wales, the Midlands and Northern Ireland ahead of a more substantial area of rain working its way in through the night.
This rain will be taking a hold across most locations tomorrow - becoming increasingly widespread and offering a taste of autumn slap, bang in the middle of summer.
The wet conditions will be accompanied by unseasonably windy weather - strong gusty winds and gales for the southern coast for a time.
The rain will stall across the north and the east in the afternoon, while there will be brighter skies in parts in the south with spells of sunshine in between those blustery showers.
