More warm, sunny weather on the way today but isolated, heavy and thundery showers are likely to develop in places this afternoon. A cool-down then arrives Sunday and especially Monday, with temperatures for some falling by 10c or more. #StayHomeSaveLives
Bude, on the coast of Cornwall, topped the temperature scales yesterday, reaching 25c. We could well see that bettered today, most likely in southeast England, but change is on the way as the high pressure which has been in charge of our weather is squeezed away to the east and replaced by low pressure sliding down from the northwest.
We've already seen some signs of that change and destabilisation of the atmosphere, as some heavy downpours and thunderstorms developed yesterday afternoon and evening.
For most today though, it'll be another warm, often sunny day. The cloud leftover from those showers and storms overnight has started will clear Southern Scotland and Northern England during this morning, leaving just about everywhere dry and fine by lunchtime. But, that is only part of the story as some rain will get into the northwest of Scotland this afternoon as a weather front moves in. And at the same time, some isolated but sharp and thundery showers will develop through parts of Wales and England. Most of these will be into Eastern Wales, central and southern England, but one or two could pop-up elsewhere.
Temperatures will be warm again today - highs in Scotland, Northern Ireland and the far north of England will get into the mid-teens, much of England and Wales the high-teens or low-twenties and southern England, especially the southeast into the mid-twenties. The average for the time of the year around 10-13c, depending on whereabouts in the country you are. We'll be heading back towards or even below those sort of numbers soon enough though.
This evening and overnight, any showers across England and Wales will die out. The weather front in Scotland will continue to move southeast though, weakening as it does so, meaning there'll be some patchy, drizzly rain on it at most by the time it reaches southern Scotland during the early hours. What it will be doing though is introducing colder air behind it, with a touch of frost possible in parts of the northern half of Scotland by dawn.
Pressure will be falling during Sunday morning, as a small area of low pressure slips southeast, and that's going to help to develop some further heavy, thundery showers in central and southern England during the afternoon. There'll also be some more general rain affecting parts of Ireland and perhaps clipping western Britain - particularly Wales and the far southwest during the day, along with one or two showers across the north of Scotland. Elsewhere though, it's again mostly dry, but with more in the way of cloud about, even so, there'll still be some sunny spells.
Everywhere will be at least a touch cooler than today, with colder air slipping south during the day. The mid-high teens will still be warm enough for much of England and Wales though, and southeast England will again break the 20c barrier. Further north it will be that much cooler though, with a distinctly chilly northeast breeze kicking in and spreading south as the day wears on.
Overnight, clearing skies and that colder air will mean a quite widespread frost for Scotland and parts of Northern England, with one or two showers perhaps moving in off of the North Sea. Further south, it's cloudier with some of that showery rain continuing.
Easter Monday then sees the low pressure which brought the brief unsettled blip moving away to the south, although some showers may continue to affect southern England for a while. Behind it, high pressure will move in across Scotland. That's going to mean plenty of sunshine, but it'll be a lot fresher and cooler than we've been used to in recent days - especially with a keen east to northeast wind blowing across a good part of England and Wales. Along the east coast, 5-8c could be about your lot on Monday afternoon, with highs elsewhere reaching 10-13c typically, with the southwest of the country best placed for the warmest temperatures.
Then next week, high pressure stays with us but will be sinking southeast. There'll be some frosty nights, but daytime temperatures will become warmer again.
