The UK is bracing for an "intense" hot spell - with temperatures set to soar to 26C.
Weather experts have pinpointed Friday and Saturday as the days Brits can expect the mercury to rise most dramatically, signalling the arrival of more widespread sunny weather.
Three areas of the country - London, Birmingham, and Northampton - are in line for what could be "the most intense heat" of the new hot spell. The Met Office's Ellie Glaisyer forecasted: "It will generally be a lot more settled this week. It will start to feel much more pleasant with temperatures on Tuesday likely to reach the very early 20s in the south."
"And then later on in the week, we could see temperatures of around 22C to 23C, while the north is likely to reach temperatures in the high teens." Another forecast from the Met Office suggested that Saturday could be the warmest day of the year so far, with temperatures in the southeast predicted to hit 26C.

James Madden from ExactaWeather, meanwhile, predicted that the warm trend will continue. He said: "Beyond this and from the early part of next week, we are then set to see high pressure taking over. And this will bring a gradual rise in temperature values to something much warmer than average and potentially hot for the time of the year and from next week and in the run up to the middle of May at the very least."
A midweek update from Netweather TV's blog also gave a sunny outlook with some rain on Tuesday, reports Birmingham Live. It read: "High pressure will build through Tuesday and Wednesday, bringing warm and sunny weather to most of England and Wales and temperatures into the low 20s Celsius."
"However, on Tuesday, there will still be a scattering of sharp showers, which are most likely to especially affect the Midlands and the north of England. It will generally be cloudier in Scotland and Northern Ireland, but with some brighter spells, and rain will affect the north and northwest of Scotland on Wednesday."
