Friday
A cloudier start for many, best of the sunshine further south. It will remain dry for most. Where the cloud is thickest over the Pennines there could be some light rain and drizzle. Through the afternoon the cloud largely breaks up allowing for sunny spells to develop more widely and temperatures to rise to very warm values across central and southern England and Wales, warm further north. Highs of 20 to 22C in the north and 26 to 28C in the south.

Friday Night
A fine evening for most. Overnight, cloud will thicken in the north of Scotland particularly where some patchy light rain could fall. Some cloud building elsewhere across the country and the risk of possible drizzle cannot be ruled out under the thicker cloud. Best of the clear spells across southern England. A relatively cooler night with minimum temperatures dropping to 9C in places to 13C.

Saturday
Another predominantly dry with sunny spells, though some thicker cloud will bring the risk of some light rain and drizzle for isolated coastal places. There is also the risk of a localised shower affecting one or two places across central into southern England during the afternoon. Highs of around 22C in the north and 27C in the south, although the far north will remain cooler with temperatures reaching around 16C.

Sunday
High pressure to the west of the British Isles will maintain dry and largely sunny conditions. There may be a little more cloud across Scotland, but most places will enjoy prolonged sunshine. Highs of around 22C in the north and 26C in the south and west, 17C to 23C further north.
