Monday
A dry and chilly start inland, a few showers in coastal districts in the west. Early sunshine inland giving way to building clouds, which develop increasingly widely into showers by the middle of the day onward, with some heavy bursts into the afternoon with hail, chance of isolated thunder. Fairly light winds, so showers will drift around slowly. Some places escape dry completely. Sunny spells best near coasts in afternoon. Highs 11 to 14C, warmest central-east England.

Monday night
Showers fade into the evening to leave clearing skies for many places. Some high cloud to the southwest thickens further into the night to bring some rain to Cornwall, later Pembrokeshire, also southern counties of Ireland. Local mist patches forming in inland valleys, a touch of frost by dawn on Tuesday. Light winds for most places, more breeze around southwestern coasts. Lows -1 to 2C, local chillier spots for rural Wales, northern England and Scotland. Milder near coasts.

Tuesday
Largely dry for central and eastern areas, with sunshine mainly in the east and northeast of England and Scotland. High cloud builds from the southwest over many places and a weak front brings patchy rain to Wales, southwest England and Northern Ireland, also southwest Scotland with time. Odd spots may reach the Midlands. Some steadier and heavier rain develops across Ireland as south to southwesterly winds increase. Highs at 13 to 16C, warmest eastern England.

Wednesday
Low pressure and a frontal system to the west brings rain and low cloud across Wales, northwestern England, western and southern Scotland and Ireland. Turning showery from the west. Cloudy with a little patchy rain into the Midlands and central-southern counties. The east of England stays drier with varied cloud and some sun. Strong south to southwesterly winds. Highs at 13C in the cloudy, damp west, 18C in sunshine in the east.
