Britain is set to bake in the hottest September heatwave in more than a century.
Temperatures could shoot past 30C in the next few days with Brits given the go-ahead to get the barbecues out.
A tropical plume from the Azores in the Atlantic Ocean will kickstart an Indian summer of glorious weather early next week.
Jim Dale, meteorologist for British Weather Services, said: "Just as people were putting away the barbecues and sun creams, it's time to get them back out again.
"Early next week we are likely to see temperatures lift into the 30Cs across parts of Britain as heat arrives with a vengeance."
The year 1906 currently holds for top mark for the hottest September on record when Britain melted in a sweltering autumn heatwave.
The mercury pushed 35.6C in Bawtry, South Yorkshire, on September 2 of that year.
The Weather Outlook forecaster Brian Gaze said: "The upper-20s are possible, with even 30C not out of the question amid Indian Summer-style autumn warmth.
"Computer models show a big ramp-up in temperatures at the weekend.'
Weather website the MetDesk added: "There are tantalising signs of summery weather later this weekend and next week."
But the "subtropical swell" could create a north-south divide with the hot air plume set to be restricted to the south of England.
The north of England and Scotland face being battered with wind and rain.
With scorching weather on the horizon, bookmakers Ladbrokes have slashed the odds from 5/1 to just 6/4 that a temperature of 30C will be recorded somewhere in the UK.
Spokesman Alex Apati said: "We're strapping ourselves in for a scorching September and there's every chance we even see 30C temperatures before the month is out."
