The Extreme heat warning remains in place until Sunday, with much of England and Wales likely to see temperatures into the low-to-mid 30s Celsius, with a chance of an isolated 36C on Saturday and Sunday. The heat warning highlights the potential impacts these levels of heat can have on health, transport and infrastructure.

Heatwave continues

Thanks to the influence of high pressure positioned over the UK the heat will continue to build through the rest of week, peaking on Friday and Saturday.

Heatwave criteria is being met, with temperatures widely into the high 20s Celsius low 30s Celsius across England. Scotland and Northern Ireland could reach official heatwave criteria by Friday.

Met Office Chief Meteorologist Frank Saunders said: “Persistent high pressure over the UK means temperatures have been rising day-on-day through this week and it is important people plan for the heat. Temperatures are expected to peak at 35C on Friday and possibly 36C on Saturday and Sunday. Even beyond this, hot conditions will persist in parts of the south of the UK as far as late Monday, and it will turn increasingly humid.

“We will also see some warm nights, with temperatures in some places staying in the low 20s Celsius.”

Thunderstorm warnings

Yellow thunderstorm warnings have been issued for much of the UK, beginning in Scotland and Northern Ireland from Sunday afternoon. As the hot weather subsides in the north, the change brings with it the risk of some intense thundery downpours and the chance of some surface water flooding.
