A thunderstorm alert has been issued as forecasters say a "Spanish plume" will bring weather chaos to the UK before temperatures rise to 30C next week.

Netweather issued a thunderstorm warning lasting until 6am tomorrow (Saturday, August 19). It covers almost all of the UK up to the Scotland-England border, although the south-east is where conditions are expected to be most severe.

It states that "a swathe of heavy rain along an arcing cold front" will push north and north-east this afternoon (Friday, August 18), with an area of low pressure spreading "north across Ireland, Wales, Midlands and N[orth] England during the evening".

There is "a risk of some embedded thunderstorms across" Ireland and Wales, as well as "a risk of localised flooding".

"Heavy showers and thunderstorms look to develop" across central England, the south-east and East Anglia late this evening and into Saturday, Netweather added.

The Met Office has thunderstorm warnings in place across the south and south-east, and the Environment Agency warned: "Local flooding is possible from surface water in parts of the Northwest, South and East of England, London and the Midlands on Friday and Saturday. Land, roads and some properties may flood and there may be travel disruption."

Netweather forecaster Jo Farrow said the "Spanish plume" bringing humid air over southern Britain is what will make this evening "tropical" and "muggy".

Despite the expected storms, temperatures in London should feel like mid-20Cs overnight.

Farrow said: "It’s not just heat from the south. Certain setups result in muggy, very warm weather here in the UK accompanied by thunderstorms and heavy downpours."

Luckily conditions are expected to improve next week as hot weather building from the continent could see the mercury rise significantly.

Netweather forecaster Nick Finnis said previously that temperatures could peak at 30C on Tuesday (August 22) "as a heat dome building north-east from Iberia across France clips south-east England".

He added: "Hot weather building over France, where temperatures look to reach 40C as far north as Paris, will creep into the south-east of England by Tuesday, where temperatures may reach 30C in the afternoon under sunny skies and humid too."
