The warning lasts two days
The Met Office has escalated its heat health warning from amber to red for Wednesday and Thursday (June 24 and 25).
Temperatures could rise as high as 40C on Wednesday in the late afternoon and early evening, while on Thursday it will be very slightly cooler at 39C. The red warning means ‘extreme heat’ and covers all of London, much of the south east and good chunk of the Midlands and West Country and parts of Wales.
Friday (June 26) looks to begin a slow downward trend in temperatures, with highs of around 29C. Saturday and Sunday (June 27 and 28) are cooler still, at around 26-27C.
