Thursday
High-pressure moves to the east of the country on Thursday. A chilly start, some low-lying mist in northern England. 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 west Ireland and Scotland later. England and Wales remain bright likely all day, cloud only beginning to build into the southwest later. Highs at 14C in northern Scotland, 17 to 19C Ireland and northern England, 20 to 22C in central and southern England.

Thursday Night
The band of rain in the northwest sweeps east across Ireland and into central Scotland on a brisk southwesterly wind. Cloud begins to build in Wales and western parts of England, with the rain reaching northwest England, and later west Wales. Central England will see cloud build but remaining dry, and the east of England maintains clear skies most of the night. Lows at 11 to 13C.

Friday
A weak front moves slowly 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. Southeast England stays dry with a mix of cloud and sun. Brighter spells develop in Ireland and Scotland with time, but the southwesterly wind remains strong, pushing showers into western areas, some extended falls west Scotland. A cooler feeling behind the front, with highs at 13 to 16C across Scotland, Ireland, and northwest England and Wales. Much warmer south and east, at least 20C for many and up to 25C in the southeast.

Saturday
A chilly start in the north on Saturday. Wind will strengthen and showers will affect northwest parts of Ireland and Scotland. The showers could become quite frequent with heavy bursts, and pushing further east into the countries for several afternoon hours. Elsewhere will be mostly dry and fine with sunny spells; a few drizzly showers into hilly northwestern areas of England and Wales. Feeling warm and quite humid in the south of England where little wind is expected. Highs at 17 to 20C for many, nearer 15C in the far northwest.
