Brits basking in prolonged spells of sunshine and warm temperatures have been warned to expect thunderstorms and rainfall rolling in from Europe.
The sustained good weather is predicted to come to a crashing, but short-lived, pause as an area of low pressure sweeps in, bringing with it the threat of thunder and heavy showers for many areas during the early part of this week.
Some forecast models claim that the persistent low settled over France and parts of Spain will nudge towards southern areas of England raising the risk of some quite potent thundery showers for the south and Midlands.
As the week progresses, the showers become less frequent with high pressure taking control again from the north. However there is a threat of more widespread rain in the north-west.
But while some areas are due explosive weather, others will keep enjoying the glorious heatwave.
The best of the sunshine is expected in the Midlands and south of England with temperatures around 3C to 5C above normal under high pressure.
Many locations will see the mercury soaring into the low 20s C but it could sizzle at around 24C or 25C in and around London.
Met Office meteorologist Greg Dewhurst says balmy conditions are being dragged in from the continent.
"On Sunday we had a high of 24C (75F) and that was in Sheffield and the day before we had 23C (73F) – usually in May we expect highs of around 17C (63C)," he said.
"Temperatures in the low to mid 20s should continue for this week, with quite widespread warmth across the country.
"But an easterly wind will make it feel a bit cooler across the North Sea coast as we move on.
"UV (ultra violet) levels are generally high across the UK as well, so people should make sure they’re protected from the sun."
The summery feel won’t extend everywhere with cloudier and wetter spells over the north-west of Scotland and Ireland with frontal rain bands brushing the area at times, expected to clear by Wednesday.
Temperatures may struggle into the mid to high teens under the cloud cover and there is a chance of some unsettled conditions from the Atlantic piling into north-western areas.
Early indications for June suggest more unsettled weather moving in and temperatures dropping to normal levels for the time of year.
A spokesperson for The Weather Channel said: “Weak pressure gradients under higher pressure will keep conditions mostly sunny with maximum temperatures between 3C and 5C above normal and higher in places.
“The exception being over Ireland and north Scotland where the proximity of a cold front will maintain mostly cloudy weather with rain, or showers, moderate south-westerly winds. It will be less warm with nearer to normal temperatures.”
Forecasters are predicting the sunshine is set to last another two weeks – meaning the Bank Holiday weekend could be a sizzler at temperatures soaring to 23C.
The pleasant spell will continue until the end of May with the fine conditions dominating for some time, various computer models show.
A spokesperson for The Weather Channel said: “From this weekend and throughout next week, temperatures will be above normal across much of Europe.
“This is due to an area of high pressure becoming dominant.
“Forecast models indicate that above normal temperatures are likely to persist for the rest of May.”
