UK weather: Temperatures over 30C on way for parts of UK

A buckle in the jet stream attributed to the energy input from Storm Debby is thought to be behind the warmer weather.

The jet stream is a fast-flowing current of air that travels around the planet. It occurs when warmer air from the south meets cooler air from the north.

The blast of heat may be short lived, with heavy and thundery showers likely to develop as cooler air moves in on Tuesday.

“Although still a little uncertain at present, temperatures are likely to get into the low 30s Celsius across the south-east of England, and possibly even a little hotter,” BBC Weather presenter Stav Danaos said.

“There is a chance of something around the mid-30s in the hottest spots.”

By next week, forecasters suggest temperatures will return to closer to normal across the whole of the UK.

Before Sunday, conditions will remain fairly changeable, with rain expected in western parts of the country on Thursday, before sunny spells for certain areas on Friday and humid weather on Saturday.

Conditions could be windier than usual in some western and north western areas.

Many parts of the world are currently experiencing above-average temperatures, with meteorologists saying this is largely a result of global warming.
