Event Extreme heat warning issued for Thursday peak
The Met Office issued a rare amber extreme heat warning for parts of England on Thursday from 0900 BST to 2359, where temperatures could peak at 37–38°C in the Midlands, east, and south-east regions.
“While the peak heat will be more short-lived than recent heatwaves, temperatures widely into the mid-30s Celsius on Thursday brings the potential for impacts for some, which is why a Met Office warning has been issued.”

“We've seen temperatures hit 38C in June, 35C in early and late July, and this threshold is looking to be reached again in the next few days. These statistics are a clear reminder – if one were needed – of the stark changes that we are seeing in the UK's climate.”
