UK hot weather: Exact date three-day 30C heatwave to blast Britain as maps turn red
Forecast data shows London and areas south of the capital, including Sussex and Kent, turning red ahead of a three-day heatwave in days.
Millions of Britons are set for a new 30C blast last this month, maps show, as the country braces for a scorching three-day heatwave.
Forecast data collected by WXCHARTS.COM and Netweather shows mutiple regions south of Nottingham in the mid to upper 20s with highs of 30C in London on August 13.
The following day the hot temperatures will broaden, with London and areas south of the capital, including Crawley and Royal Tunbridge Wells, turning red on August 14.
Various other southern towns and cities including Reading and Oxford could also be in the upper 20s, according to the weather forecast site.
Birmingham is set to see 26C, with 27C temps in Worcester. A long strip of 27C and above also running through south west England including Glastonbury, Yeovil and Taunton in Somerset.
The north of England is expected to be cooler with areas around Liverpool and Manchester between 17 and 22 degrees.
A similar pattern is expected on Thursday, August 15, though London will be a couple of degrees cooler, with highs of 30C along the south coast.
Meanwhile, Met Office yellow warnings are in place today for thunderstorms expected to ravage parts of the UK in hours, fresh map analysis shows.
Affected areas could see up to 30mm of rain hammering down within an hour, resulting in disruption on the roads and railways, the national weather agency warned.
The storm risk is heightened across much of the south-east, although some areas are likely to avoid it all.
The Met Office said in a statement: "Whilst many places will stay dry, a few thunderstorms are likely to break out on Wednesday. These are possible at any time, but become more likely during the afternoon and evening.
"Where these occur, 20 to 30 mm of rain is possible within an hour, and perhaps as much as 50 mm in two hours; the latter more likely across southeast England and parts of East Anglia during the evening. Lightning will be an additional hazard."
