UK weather forecast – Exact date sizzling 35C heatwave will end – with thunderstorms and heavy rain on the way

BRITS are currently baking in the heatwave but it’s expected to end with a bang next week.

The Met Office has issued an extended Amber Extreme heat warning covering large parts of England and Wales which now covers July 17, 18 and 19 with temperatures expected to hit 35C.

Forecasters expect it to be sizzling next Tuesday but the heatwave is due to come to an abrupt end on Wednesday as temperatures plummet to just 17C in the east of the country.

The country will be hit with thunderstorms and heavy rain as the cooler weather comes in.

Temperatures are expected to steadily increase as the week continues, with the Met Office saying Sunday will be “very hot”.

In its long range forecast, it said: “Temperatures will rise through the weekend, with most areas becoming very warm or hot, with the potential for an exceptionally hot spell in parts of central, south, or east England.”

There could also be the occasional thundery shower in the south and southwest.

Wednesday though will see a change with temperatures seeing a return to normal although it will still feel warm, particularly in the south.

Britain has basked in sweltering temps this week, leading the UK's Health Security Agency Heat Health Alert to reach Level 3 - which means that temperatures are likely to have a high impact on public life.

Chillier conditions will have spread to Scotland, Northern Ireland and the north of England along with some showers in the northwest. 

Met Office Deputy Chief Meteorologist Rebekah Sherwin said: “From Sunday and into Monday, temperatures are likely to be in excess of 35°C in the southeast, although the details still remain uncertain.

"Elsewhere, temperatures could be fairly widely above 32°C in England and Wales, and in the mid-to-high 20s Celsius further north."

Dr Agostinho Sousa, Head of Extreme Events and Health Protection at UKHSA, said: "Heat-health alerts have now been issued to the majority of the country, with temperatures set to remain consistently high throughout the duration of this week. 

"Most of us can enjoy the hot weather when it arrives, but it is important to keep yourself hydrated and to find shade where possible when UV rays are strongest, between 11am and 3pm. 

"If you have vulnerable family, friends and neighbours, make sure they are aware of how they can keep themselves protected from the warm weather."

It comes as the mercury soared to a whopping 32C on Monday in Northolt, West London, the Met Office revealed.

The UK's record high for 2022 currently stands at 32.7C, recorded at Heathrow on June 17.

The highest recorded temperature recorded in the UK hit 38.7C at Cambridge Botanic Garden on July 25, 2019.
