Wednesday
Early on Wednesday, a band of rain stretches across east Scotland into northern England, some heavy falls in Scotland, the rain patchier into central England and Wales. The rain clears eastwards through morning with brighter spells developing behind. A few spots of rain will linger in East Anglia in the afternoon, and some showers will drift into north and west Scotland on a strengthening northwesterly breeze. Through afternoon, any rain will tend to ease with increasingly sunny conditions. High temperatures of 15 to 17C for most of Scotland and Ireland, as well as northwest parts of England and Wales. Central England nearer 21C, up to 24C in the far south.

Wednesday Night
A broad core of high pressure passes east across the British Isles overnight, easing the wind and keeping the skies generally clear of cloud. Some mist will develop in low-lying areas, particularly central and north England and Wales. Later, the wind will restrengthen over Ireland and shift southwesterly. A chilly night with lows of 4 to 6C for Scotland, nearer 7 or 8C much of England and Wales. Ireland will be milder, nearer 10C.

Thursday
High-pressure moves to the east of the country on Thursday. A chilly start, dry for most and bright with sunshine, particularly further south and east. With time, becoming cloudier into Ireland and northwest Britain, winds strengthening and rain arriving into Ireland and west Scotland later, spreading more widely into these countries into night. The east of England stays bright. Highs at 14C in northern Scotland, 16 to 18C for many, up to 21C in southern England.

Friday
A weak front moves southeastwards down England and Wales on Friday. It will bring cloud and patchy rain to Wales and northern England, a little rain later reaching further east but total rain will amount to little. Brighter spells develop in Ireland and Scotland with time, but the southwesterly wind remains strong, pushing showers into western areas. A cooler feeling behind the front, with highs at 13 to 16C across Scotland and Ireland. Much warmer in England, at least 20C for many and up to 25C in the southeast.
