UK weather forecast: Brits brace for three days of heavy rain and thunderstorms as Met Office issues weather warning

The UK is braced for three days of heavy rainfall and "unsettled weather", with the chance of thunderstorms in many parts of the country.

A yellow weather warning has been issued for the south west of England from 4pm on Wednesday until 9am on Thursday, warning of heavy downpours which could cause flooding and travel disruption.

For most of the UK, Wednesday will be a cloudy day, the Met Office said, with some outbreaks of rain, which could be heavy for Scotland, the Midlands and north Wales.

"Some of that rain could be heavy, and there is a risk of thunderstorms," Met Office spokeswoman Nicola Maxey told the Standard.

"Tonight, we will see heavy rain for Wales and south west England - we've got a low pressure system, bringing the heavy rain in.

"For London, there is a risk of showers for the rest of the week. These are showers, rather than persistent heavy rain, but some showers could be heavy."

On Thursday night, "we will see a front pushing into the north east, bringing persistent and heavy rain".

"We still looking at potential for heavy rain and thunderstorms in the south on Friday - a cloudy, murky Friday, with showers affecting central areas and chance of thunderstorms," Ms Maxey said.

"There is a risk of thunderstorms, but it doesn't mean everybody will see them.

"There is some quite warm air, so we could see temperatures in the mid 20s by the end of the week.

"It will feel fairly humid."

Temperatures will remain below 20C on Wednesday and Thursday, but will start creeping up on Friday, bringing possible temperatures of 25C in some parts of the country over the weekend.

"Temperatures might be similar what we were seeing last week, but we have a lot of cloud and rain, so it will feel humid - not as pleasant as the sunshine we had," Ms Maxey said.

It comes after the UK enjoyed the sunniest spring since records began in 1929, with sun-worshippers enjoying temperatures peaking at 29C.

The Met Office said the weather last month was “all to do with the jet stream” as it was “just buckled in exactly the right way in May”.
