Met Office predicts 34C hot spell but warns of thunderstorm 'threat' for parts of UK

A brief hot spell is just around the corner according to the Met Office's latest forecast, but some parts of the UK are being warned to expect thunderstorms as well.

Temperatures are expected to rise across the UK from Sunday, with highs of 34C predicted in the south and east. However, heavy rain and thunder could quickly follow the warm weather, which is expected to last just a couple of days.

According to the Met Office: "Temperatures are expected to rise by the start of next week, but there will also be the threat of thunderstorms for some as the warm weather breaks down."

Dan Holley, the Met Office's deputy chief meteorologist, said: "We expect to see a relatively brief hotter and more humid spell of weather for Sunday and Monday, before these hotter conditions recede on Tuesday, allowing more unsettled conditions to return."

He added: "This change to hotter conditions is caused, in part, by the effects of Tropical Storm Debby in North America. Debby is helping to strengthen the jet stream, causing it to meander over the Atlantic. This will allow hot air over France to move into the UK later this weekend, and early next week.”

The highest temperatures are expected in parts of central, east and southeast England, peaking on Monday. Many places expected to see at least 30C, while the hottest places are forecast to be 33 to 34C. Temperatures are expected to remain high overnight and humidity will also be high, especially on Sunday night in southern and western areas.

Some places, including areas of northern England, can expect thunderstorms overnight on Sunday and into Monday. Mr Holley
