BRITS will sizzle in “unprecedented” heat today with Met Office forecasters claiming it is likely the current 38.5C record will be smashed.
“It will be extraordinary and perhaps unprecedented heat”
The scorching conditions could see the mercery rocket up to a sweltering 39C in southern and eastern England by this afternoon.
According to the Met Office, it is very likely the current record set back in 2003 could be smashed.
Commuters are this morning sweltering on trains into London – with many urged to “stay home” amid delays and cancellations caused by the heat.
It follows Britain experiencing a “tropical night” with temperatures failing to fall below 20C in London, Suffolk and Norfolk, the Met Office added.
Temperatures have already reached 30C at Heathrow Airport by 10am.
Met Office meteorologist Greg Dewhurst added: ”There is a 60% chance that the temperature will reach 39C.
“It will get into the 30s across the country and reach the mid-30s in the south-east. If it is to get to 39 it will happen somewhere between London and Cambridge.
“Temperatures locally could also break July or all-time records.”
Some forecasters have claimed the roasting temperatures could feel more like 44C – weather common in countries like Egypt.
BBC Weather meteorologists said Brits could experience “extraordinary and perhaps unprecedented heat” and that the mercury could even climb to 40C.
Both Belgium and the Netherlands broke their all-time maximum temperature records on Wednesday, reaching 39.9C and 39.1C respectively, the Met Office said.
But, officials have warned people to be careful if they plan to cool off in lakes, rivers and the sea after the bodies of three people were pulled from the water after they reportedly got into difficulty.

Network Rail said speed restrictions could be introduced in areas where tracks were at risk of buckling.
London North Eastern Railway also advised customers to avoid travelling on Thursday, with heavy speed restrictions between Peterborough and London King’s Cross.
Higher temperatures are making extreme hot spells more likely and more intense, experts warn.
The Met Office also issued a yellow thunderstorm warning for most of England – except the south west – and parts of Scotland from 3pm today until 4am on Friday.
