The With Office has issued its first-ever red warning for the potentially record-breaking warm weather for this Monday and Tuesday. But the weather could quickly return to cool and rainy as the rest of the week brings temperatures as low as 10C degrees, and scattered showers across the country. The switch to cooler weather is expected to happen from Tuesday to Wednesday, and it could be accompanied by thunderstorms in some places, according to the Met Office.
The forecast for Tuesday through Thursday reads: “Tuesday will be extremely hot for many, after which Tuesday night and Wednesday will turn into cooler weather, accompanied by thunderstorms in places. Fine with a few showers on Thursday.”
Maps show lows of up to 7 degrees in Wales on Thursday, 9 degrees in Leeds and 12 degrees in London on that day.
The coolest temperatures could be felt on Friday as maps on that day show as low as 5C degrees near Inverness, Scotland.
But Friday will also see cooler temperatures in the south, with lows of 8-9 degrees in Birmingham, 10 degrees in London, 11 degrees in Bristol and 12 degrees in Leeds.

The Netweather forecast reads: “In addition to cooler temperatures on Tuesday evening, there are also likely to be some thunderstorms – some could affect eastern and southeastern England, but most of the rain will pass through western England, Wales and up south, center off the land… and maybe northern Scotland.
“Some of those downpours and storms will transition to the east on Wednesday with some brisk storms and downpours possible.”
British Weather Services senior meteorologist Jim Dale told Express.co.uk: “Given that we are going to see temperatures knocking on the door of the UK record, there is a good chance the outage could lead to severe weather.
“Monday and Tuesday look very humid and then sporadic thunderstorms will break out across France, some of which are likely to move into Britain.

“England and South Wales will be hit with the South Coast being the first big hit.”
The storm clouds, also known as ‘cumulonimbus’ clouds that bring storms and lightning to the UK, are menacing-looking multi-level clouds, extending high into the sky in towers or plumes.
They are the only clouds that can cause hail, thunder and lightning.
Explaining the phenomenon, Dale told Express.co.uk: “Thunderstorms have the potential to cause flash floods, torrential rains, hail and mini-tornadoes.”
Scattered showers will continue to hit the country over the weekend.
