It could be the hottest day of the year in the southeast this weekend, forecasters predict, with temperatures soaring around 24°C on Saturday as a burst of warm air pours in from North Africa.
So far, the hottest day of the year was recorded on Easter Friday at 23.4C in St. James’s Park.
Londoners will enjoy balmy weather for the rest of this week, forecasters say.
A “mostly dry and sunny” weekend is coming, with light winds expected, Met Office forecasters said.
However, the Met Office warned that a sun-filled Saturday, which would be ideal for a barbecue, could be followed by torrential rain and thunderstorms.
Saturday could be “wide 16-19C – with 24C the possible maximum temperature in the southeast and that would make it the hottest day of the year yet,” said Met Office meteorologist Aidan McGivern.
There will be widespread sunshine from the north of Scotland to the south of England, with only a few patchy clouds in the north and west.
The warm air is also likely to bring a few heavy showers.
Mr McGivern said: “By Saturday evening those showers should appear in the south west and spread quite widely to southern parts of England and south Wales.
“In some places it would just be a downpour, but for central and southern England and the south coast there is a risk of heavy downpours, thunderstorms and frequent lightning.”
According to BBC Weather, temperatures could remain in the mid-20s until next week, peaking at 24°C on May 17 in London.
Warm air from North Africa will bring above average temperatures for May in most places in the UK over the next week, but it will be interrupted by possible severe or thunderstorms.
The Met Office said parts of the Southeast could potentially reach highs for the week of 25C-27C.
Met Office spokesman Richard Miles said: “Right now, Tuesday appears to be the hottest day of the week”.
Throughout the week, some people will enjoy warm, sunny spells, but heavy showers will move across the country, especially in the north and west.
These can be irresistible at times in parts of southern, central England and southwestern Scotland.
Meteorologist Andy Page of the Met Office said: “The plume of warm air we expect from the south will cause higher temperatures across the country over the next week.
“However, it appears that the effects of the Atlantic trough will prevent a continued high-pressure build-up from the east.
“This means that while we may see some warm – and in some places very warm – days, the coming week will generally feel more like what we would expect from a warm period in May, with some heavy showers nearby, instead of hot summer weather.”
