High pressure in control this week will ensure fine and mostly dry weather across the UK, warm sunshine for many, just a few isolated showers in places.
Saturday was the warmest day of a sunny weekend and the warmest day of the year so far, after Kinlochewe in northwest Scotland reached 20.2C, thanks to the foehn effect of the southeasterly wind descending the western side of the Highlands. Sunday wasn't quite as warm, thanks to a pool of chillier air moving in from the near continent, the highest temperature reaching 14.9C in Porthmadog in northwest Wales.
After a chillier day yesterday and cold, frosty start this morning, milder air will spread in from the south today, so temperatures will be warmer today in the south, reaching the high teens, cooler air hanging on across the north. Generally, it will remain dry and sunny this week, thanks to high pressure in control close to the east, while turning warmer across all parts by mid-week as the warmer air spreads north. Temperatures reaching around 20C across the south, so we could see another warmest day of the year so far. Nights will still be chilly, while there will be a few isolated showers across central areas Tuesday and Wednesday, then across the far north later in the week.
For now, a widespread cold and frosty start across the UK, temperatures falling widely below freezing under clear skies overnight, the lowest temperature -6.6C at Altnaharra in the far north of Scotland. It will quickly warm up though in the sunshine this morning, with the sun stronger now than a month ago. Blue skies and sunshine for many northern and eastern areas this morning after early localised mist and fog patches clear. Cloudier skies moving north across Wales and the West Country this morning will bring a few showers. This cloud and a few showers will continue north and northeast through the day, affecting Midlands, NW England N. Ireland and SW Scotland as well as Wales. But, elsewhere, it will remain sunny and dry through the afternoon. With milder air moving in from the south, temperatures will reach 14-17C across southern areas, 10-13C across the north with cooler air here. Chilly along eastern coasts of Scotland with onshore breeze here, reaching only 9C in Aberdeen.
Not quite as cold as last night tonight, areas of cloud drifting north, thick enough to bring an isolated light shower across central areas, but areas of clear skies too. Temperatures generally falling to 4-7C generally, but across eastern Scotland may be lower and lead to a frost.
Largely dry and sunny on Tuesday, though areas of cloud bubbling up and drifting north could produce some showers across the Midlands, northern England and southern Scotland in the afternoon. Most areas will stay dry though. Warmer than today generally, temperatures reaching 19-20C across the Moray Firth in Scotland and across parts of SE England, otherwise widely reaching 15-18C. Cooler along North Sea coasts, especially coastal eastern Scotland, thanks to the southeasterly breeze off the North Sea.
Mostly dry and fine with plenty of sunshine across the UK on Wednesday, cloud will bubble up to produce a few showers across northern England, but they will be isolated. Warm, temperatures reaching 14-18C widely, perhaps 19-20C again in a few spots, cooler across NE Scotland.
The dry, sunny and settled theme continues for Thursday and Friday. The exception will be across northern Scotland which will be prone to cloudier skies and a few showers on the edge of high pressure centred further south. Temperatures reaching 13-15C in the north, 15-18C in the south.
The weekend looking mostly dry and settled, with high pressure centred over northern Britain, perhaps more in the way of cloud feeding in from the North Sea across England and Wales, so not as warm as during the week.
