Thundery rain is expected across the UK after the extreme UK heatwave comes to an end this week.
The Met Office says the scorching weather is set to disappear from the middle of this week, with scattered downpours predicted.
The weather forecasters, who issued a red and amber weather warning across the UK for Monday and Tuesday, believe the sweaty conditions are set to go from Wednesday.
Temperatures are expected to start to return closer to normal for this time of year from the middle of the week, as cooler air pushes across the country from the west.
The exceptionally hot weather will cool rapidly on Tuesday night and into Wednesday as the forecasters said there was a "low chance" of storms after the heatwave.
However, although cooler temperatures are on the way, the Met Office have suggested the UK will see bolts of lightning and thunder after days of the extreme 40C heatwave.
A spokesperson for the Met Office said: “It looks like it will ease a lot from Wednesday, cooling considerably.
“After the extreme heat it will feel a lot more comfortable, around average for the time of year.
“There will likely be some showers around and I would say a low chance of some thunderstorms.
“It is likely much of the UK will see temperatures gradually decrease to average or slightly above average through next week, though occasional thundery showers are possible in the south and southwest."
The Met Office red warning - the highest level - is for extreme heat and covers an area including London, Manchester and York on Monday and Tuesday.
It is the first time it has been issued since the warning system for heat started last year.
Health secretary Steve Barclay urged the public to look out for the vulnerable and elderly ahead of the extreme weather next week.
Mr Barclay said: “The clear message to the public is to take sensible steps in terms of water, shade and cover. That's the best way of mitigating against the heat.
“We're asking people to keep an eye out for their neighbours and those who may be vulnerable.”
