“We could see highs of 25C (77F) in London, the East Midlands and East Anglia, which will get the best of the weather.
“There will be some patchy drizzle on Tuesday and Wednesday when temperatures dip a couple of degrees maybe, but by Thursday we expect to see things on the rise again.
“If we reach 26C (78.8F) then we will have the hottest day of the year so far, but it is Friday which is shaping up to see temperatures peaking.
“We are looking at the high 20s - possibly 27C - with warm air coming up from the south. It’s going to feel pretty good.”
However, those looking for the warm run to continue into the forthcoming Bank Holiday weekend might be left disappointed.
Mr Burkill said: “This is looking like being the warmest spell we’ve had since September last year, but it might not last beyond Friday - from then we are looking at the possibility of some thunder and showers and temperatures taking a dip.”
