London weather forecast: Thunderstorms to bring sizzling UK heatwave to an end as Brits warned of wet and windy … – Evening Standard



Brits are braced for severe thunderstorms and plummeting temperatures overnight as forecasters have warned the wet weather could continue into this weekend – bringing the heatwave to an end.

A yellow weather warning is in place until 3am on Wednesday covering the east and south east of England, with lightning strikes and heavy rain expected in parts.

“Frequent lightning may occur along with heavy rain – as much as 20 to 30 mm of rain in an hour in a few places – large hail and sudden strong gusts of wind,” the Met Office said.

And the wet and windy weather is expected to continue from Thursday until Sunday, Met Office forecaster Marco Petagna told the Standard. 

It follows a sweltering day that saw the mercury reach sizzling highs of 33.2C in Kent on Tuesday.

The forecast has prompted Ryanair to cancel at least 14 departures and 13 arrivals at Stansted Airport.

In a statement on its website, the airline said: “We apologise for any inconvenience caused by this weather disruption, which is entirely beyond our control, and we are working hard to minimise the disruption to our operations.”

Mr Petagna said showers have already broken out over the south east, which are “likely to become increasingly heavy”. 

Londoners should also expect thunderstorms throughout the evening, with temperatures dropping to between 16 and 18C across the south east, he said. 

Mr Petagna added: “Tomorrow will be a much fresher day in the south east. It will be generally dry with some sunshine.” 

He said temperatures across the UK are set to peak around the high teens or low 20s on Wednesday.

“It will be a good nine degrees down,” Mr Petagna said. “The mercury could possibly peak at 24C in the south east.” 

The forecaster added that further rain is expected in the south east by Thursday and Friday, with a wet and windy weekend ahead. 

He said: “Generally we are expecting cooler and more changeable weather.”

Brits have enjoyed weeks of heatwave conditions, with a balmy weekend bringing highs of 30.2C on Sunday.

It comes amid a sweltering European heatwave, with holidaymakers in Portugal and Spain feeling the brunt of the sun.

Parts of England have spent the equivalent of around two months of 2018 without any recorded rainfall.

The south east clocked up 64 days of zero average rainfall between January and July, while central England had 54 days.

‘Runaway global warming could cause permanent prolonged UK heatwaves’

The last time both regions recorded a higher number of rain-free days in this seven-month period was the mid-1990s.

Following the long hot summer, the UK could see warmer-than-average temperatures in the autumn, according to the Met Office.

Its three-month outlook does not suggest the hot weather will last that long but it may be “warmer than average”.

The outlook – used by planners, businesses and government to start plotting weather-related decisions – shows an increased chance of high-pressure systems close to the UK, meaning settled conditions are more likely than unsettled weather from our typical Atlantic weather systems.
