Temperatures are set to soar in the next couple of days across the UK, forecasters say – but don’t expect it to last.
All regions are tipped to enjoy a fine few days, with cloud clearing today to make way for bright skies and late summer sunshine.
It is expected to be warmer than the average for this time of year, although Thursday and Friday will see a return to miserable weather.
Tomorrow it is expected that some places will bask in up to 29C – a long way up from the normal 18C at the start of September.
Annie Shuttleworth, a Met Office forecaster said: “Despite a cloudy start to Monday, conditions will be clear and bright with hot temperatures for large parts of England and eastern Wales as the result of continental air moving in from the south.
“This air will start to push through the country on Tuesday and Wednesday, dragging temperatures as high as 29C (84.2F) for parts of the south-east while Scotland and Northern Ireland will also move into the mid-twenties.
“It’s going to be very warm for the time of year and could even be rather uncomfortable for people trying to sleep at night, with temperatures remaining at around 18C (64.4F) during the evening.”
Ms Shuttleworth said this meant a “decent chance” of an official heatwave for parts of central England and eastern Wales, where the temperature threshold needed over three days is 25C (77F).
However, she warned of an area of low pressure moving in from the west on Wednesday afternoon, bringing with it grey and wet conditions for much of the UK on Thursday.
Thunderstorms are also expected in the second half of the week to conclude the hot spell.
Today will be cloudy for much of the region, with a top temperature of 24C.
There will be bright spells breaking through this afternoon, however, the Met Office predicts.
Forecasters have warned of some fog patches overnight, with an overnight temperature of around 12C.
Tomorrow will be warmer, with prolonged sunny spells as the mercury rises to 28C.
Wednesday is also expected to be warm, but this will make way for heavy showers on Thursday and Friday with a risk of thunder which will make it cooler.
People in the North East can look forward to warmer weather as today progresses, with the east of the region predicted to be generally bright.
