UK weather forecast LIVE: EXACT date 20C blast to hit Britain this week as Met Office reveals Jubilee heatwave

BRITS are in for a 20C scorcher in just days when a nine-day mini heatwave sets the scene for three months of glorious weather.

Temperatures will start to heat up from May 5, with experts predicting the mercury will hit 20C, with plenty of warm air and sunshine forecast

Thursday will become balmy with minimum temperatures of 18C, before hitting 19C in time for the weekend.

London and the south-east are set to see the best of the warm weather with a scorching 20C predicted to hit the capital.

Forecasters have predicted warm weather stints in the second half of May, with hot spells in June even more likely.

It’s all thanks to a “Spanish sizzler” blowing in from the continent in the week of the Jubilee from June 2 to 5, when Her Majesty will mark 70 years on the throne.

The MEt Office’s long-range outlook over the period states: “Chances of hot weather and heatwaves are increased compared to average, especially later in the period. There is an increase in the likelihood of warmer-than-average conditions over the three months.”
