Saturday
A weak front will continue to sink south across England and Wales on Saturday bringing mainly cloudy skies as it passes through but also the risk of some patchy light rain. Dry with sunny spells otherwise. Meanwhile, it will be a windy day across Scotland, Northern Ireland and northern parts of Ireland with sunny spells and showers, some of these merging into longer, heavier spells of rain in the west. Cloud thickening over northwest Ireland through the afternoon before more persistent rain moves in later. A largely dry and fine day for southern Ireland. Highs at 21C in southeastern England, 15 to 18C for most other areas.

Saturday Night
Heavy rain affects northwestern parts of the island of Ireland, northern and western Scotland and northwestern parts of England overnight from Saturday into Sunday. Rain could be torrential at times for western Scotland. Staying dry for much of England, Ireland and Wales as well as eastern Scotland but fairly cloudy here. The best of any clear skies will be over central and southern England. Overnight lows at 9C in the north of Scotland, more widely 11 to 15C.

Sunday
An area of low pressure will track east across Scotland on Sunday. This brings the risk of some heavier periods of rain here, together with stronger winds. Further rain may affect northern and western Ireland though this eases through the afternoon. Rain becomes confined to the far north of Scotland later. High pressure will bring dry and fine conditions in the south including eastern Ireland, most of England and Wales. Warm temperatures for most; highs at 24C in southern England, 23C in southern Ireland, 22C in eastern Scotland, 16C in northwest Scotland.

Monday
Staying dry with a good deal of sunshine for most on Monday as high pressure over the continent extends towards the British Isles. Temperatures becoming very warm in the south too. Northern and western parts of Scotland and Ireland will see more in the way of cloud and some outbreaks of drizzle and rain. The best of the sun over southeast England. High temperatures at 19 to 28C.
