Saturday
Low pressure moves swiftly across central England and Wales, bringing a period of rain, tending to break up from the west into clusters of showers, these most frequent for north-west England in the afternoon. Patchy rain slow to fully clear from East Anglia. A little sun may come through in the west later. A few showers for western Scotland. Largely dry for north-east Scotland. Isolated showers for Ireland, fading. A risk of gales around the Dover Strait at first. Highs 7 to 13C.

Saturday night
Rain moves back into south-western areas on Saturday evening, becoming extensive for central-southern England and Wales through the night, although patchy toward eastern counties. Winds strengthening around south-western coasts. Some rain also moving into Northern Ireland and perhaps south-west Scotland before dawn. North-east England and much of east and northern Scotland will see clear spells and a risk of frost. Lows 6 to 9C south, 0 to 3C north.

Sunday
Areas of rain will move across the country. Some persistent falls over a few hours, tending to break up into clusters of showers from the west. Snow over the southern Scottish Highlands.

Temperatures ranging from 12 to 14C in the south of England, to just 5 to 8C in Scotland.
