High pressure sucking warm air up over the UK this weekend bring mean summer-like temperatures for many. Cooler weather will be well on the way by early next week though.
An anticyclone will give a fine, dry weekend for most, before moving onto the near continent. As it does so, it'll suck warm air up from the South with temperatures tomorrow perhaps getting as high as 24 or 25C locally over parts of East and South East England. Sunday though will begin to see a change, as cloud and a few showers move into Scotland, Northern Ireland and some other western areas later. This'll herald the arrival of much cooler, fresher weather that'll spread to all parts during Monday.
After a chilly start, mist and patchy fog mostly over rural parts of East Anglia, the South East and South Wales will soon clear. There's also some cloud across Northern Ireland and West Scotland, but this too should clear, leaving most parts with a fine, sunny, spring day. Temperatures will quickly rise through the morning making it pleasantly warm by the afternoon in a mostly light breeze from a southerly quarter. A few coastal areas may notice a sea breeze by the afternoon, as temperatures reach 15 to 18C in the West and 19 to 22C in the East and South. The exception will be the far North West of Scotland and the Northern Isles where a South West wind will bring occasional drizzle, limiting temperatures here to 11 to 13C.
A fine evening and night will follow with clear spells. It'll turn chilly again after dark, with a gentle southerly breeze allowing mist and patchy fog to form again towards dawn across England and Wales. A touch of grass frost is also possible in a few vulnerable rural valleys, with lowest temperatures mostly in the range 3 to 8C. Later in the night cloud will begin to filter into parts of North and West Scotland and perhaps Northern Ireland, bringing a few showers by morning.
Sunday will be another lovely fine, spring day over most of England and Wales before cloud begins to move into Cumbria and the western fringes during the afternoon. You'll certainly need the sun cream despite it being somewhat hazy sunshine, in a warm or even very warm afternoon. This'll 'trigger' some coastal sea breezes again, in an otherwise light or moderate South to South Westerly wind. Temperatures should reach 19 to 22C fairly generally, with 23 to 25C possible briefly across parts of Eastern England and to the North of London but where it clouds over later 16 to 18C is more likely.
After a bright start towards Lothian and The Borders, Scotland and Northern Ireland will be more cloudy on Sunday. There'll also be some showers moving in from the North West, but many of them should be light before brighter weather spreads from the North West to give particularly Highland and perhaps parts of Northern Ireland some sunshine to end the day. It'll be cooler and fresher here as winds turn into the West or North West, with temperatures here getting no higher than 10 to 14C.
A summery evening should follow across The East Midlands, East Anglia, central southern England and the South East, before cloud and the odd light shower by then into northern England and Wales move in after dark bringing a change. Clearer but colder weather over Scotland and Northern Ireland with just a few showers in the North and West then follow, spreading to most parts by morning. It could then be cold enough for a touch of frost in some sheltered Scottish glens despite a West to North Westerly wind, with lowest temperatures 1 to 4C in the North and 5 to 8C further South.
Next week sees the run up to the Easter break, when winds between West and North common at this time year, bring somewhat more changeable conditions. The North and North East will be colder at times with occasional showers that could occasionally be wintry on Scottish hills, while the South and South West tend to be drier and brighter with milder interludes
