Brits are set to scorch in temperatures that will climb to 35C - as a 10-day heatwave is on the cards, forecasters claim.
By the end of the week, the mercury is forecast to reach highs of 24C by 4pm in parts of the South - such as London and Peterborough.
The following Monday, July 11, will welcome highs of 28C in the southeast, with London, Southampton, Oxford and Cambridge painted an angry red on charts as the 10-day heatwave begins.
Netweather meteorologist Nick Finnis described the forecasts as "eyebrow-raising".
He said: "The GFS numerical weather prediction model has been churning out some eyebrow-raising temperature charts over the weekend, one deterministic run on Saturday forecasting record-breaking heat for England on the 16th July, with temperatures reaching 41C inland across southern England and East Anglia."
Ms Finnis added: "Temperatures are set to be on the rise through the coming week, as we lose the showery trough of low pressure that’s been with us and see high pressure build in from the Azores in its place.
"Although the threat of showers or longer spells of rain continues for the northwest over the next few days, the high centred to the southwest of Ireland looks set to extend across the UK and increasingly influence the weather across most parts by the end of the week and through the weekend, with a corresponding increase in sunshine and also temperatures.
"Temperatures in the south and east look set to reach highs of 24-27C on Friday.
"Perhaps a degree or two hotter over the weekend towards eastern England, perhaps reaching 28-29C in London, as the upper level ridge builds in stronger from the southwest, with an increase in air thickness leading to higher temperatures."
As the week goes on high pressure is set to build in many parts of the country, leading to temperatures in the mid twenties, the Met Office reports.
The Met Office's official forecast says: "Southern, and often eastern areas fine with sunny periods becoming warm from Friday.
"Remaining cloudier and breezier in the northwest with rain at times. Southern regions potentially very warm Saturday."
Just as schools break for the summer holidays, the 10-day heatwave will welcome in temperatures of up to 35C.
WXCharts has forecast that on July 13, temperatures will reach highs of 32C in the south, 31C in the midlands, 25C in Scotland and 30C in the northeast.
High temperatures will remain throughout the third week of July - with London seeing highs of 34C, and Birmingham reaching up to 30C on July 16.
Martin Bowles, senior meteorologist at the Met Office, said: "Looking at the second half of July, around the start of the school holidays, it does look as if the most likely weather across the UK is settled and warm. There are good signals for dry, sunny and warm weather.
"The general outlook is for it to be high 20s with a chance of it reaching 30 in one or two spots."
Weather Outlook forecaster Brian Gaze added that he wouldn’t be surprised if temperatures did reach high as 35C.
However, the Met Office reckons temperatures will still sit at a sweltering 30C.
Brian told The Sun : “At the moment long-range computer models are suggesting an increased likelihood of very warm conditions during the last third in July.
“Temperatures in the UK reached 32.7C earlier this month and typically the hottest weather of the summer comes in July or August.
"I wouldn't be surprised if temperatures climbed to 35C (91F). To put a little context on that, the hottest day in the entire decade of the 1980s was 34.4C.”
The h ottest day of the year so far was recorded in St James Park, central London, where the mercury soared to 28C on 15 June.
