Britain is on course to be baked from tomorrow as plumes of warm air from the continent engulfs the country. Temperatures are poised to sky-rocket into the high twenties across vast areas of the UK during the early part of the week and could even “nudge 30C”, forecasters say.
The latest maximum temperature maps show the length of the country turning red-hot by Wednesday.
The mercury is set to reach highs of 27C across southern, central and eastern areas of England by 3pm on Monday, the latest maps suggest.
Britons can expect temperature dials to hit 28C on Tuesday as the sweltering conditions spread in a westerly direction.
Hot-air is poised to spread further north by Wednesday, with the best of the conditions remaining the south east, with highs of 29C forecast.
The Weather Outlook latest forecast said: “Very warm air upper level air starts pushing northwards across southern and central regions today, but in the north west heavy outbreaks of rain develop.
“During the next couple of days temperatures continue to rise and values may well nudge 30C (86F) locally.
“Through the middle part of the coming week the risk of downpours and thunderstorms increases.”
Met Office forecaster Annie Shuttleworth said: “We are expecting temperatures to rise at the beginning of the new week.”
She added: “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.”
Ms Shuttleworth added temperatures overnight will remain at around 18C.
The area of high pressure is set to fade towards the end of the week as wet-weather and even thunderstorms develop.

“Occasional shallow lows are expected to head in from the west during this week, bringing some rain and potential for thundery outbreaks especially towards the south-east, but in between the ridging high pressure will bring spells of settled dry weather.
“Southerly winds will blow more frequently than usual, and so temperatures will generally be above average for the time of year.
“Sunshine totals will probably be rather higher than those during the preceding settled spells in most parts of central and eastern Britain, with a change of prevailing wind direction meaning that there will be less of the stratocumulus heading in from the North Sea.”
