This week’s ‘heatwave’ bringing scorching highs of just 30C will soon be a mere memory for most of the UK as the wet weather returns with a vengeance.
Hopes the beach temperatures would linger into the weekend have been dashed by storm forecasts predicting days of downpours for some parts of the UK.
While much of the country will remain dry from Wednesday, a band of rainstorms washing in from the southwestern coastlines will track their way up the country and begin unleashing the potential for floods, travel chaos, and lightning strikes by Thursday.
The forecast promises a dramatic change from today’s conditions, as parts of the UK are set to be bathed in warmth of up to 30C – as Brits got a balmy start to September following the disappointing summer.
In a bright start to the official autumn, the Met Office said some areas are edging close to recording heatwave this week as pupils headed back to school.
But before anyone starts packing up the buckets and spades for a weekend at the beach – meteorologists are warning temperatures are forecast to fall further following forecast storms.
A series of Yellow weather warnings issued today predict lightning and heavy rain washing through Wales and England’s South West by Wednesday.
The Met Office says the area of showers should begin to move northwards across southwest England and south Wales from Wednesday afternoon, while much of the rest of the country remains dry.
The rainstorms are due to move to the Midlands, England’s East and into Northern Ireland by Thursday.
By late Thursday, the heavy rain and lightning warnings will also envelop much of the East of England, West Midlands, Greater Manchester, Lincolnshire, Yorkshire and as far north as Newcastle and Northern Ireland.
The warnings last until 8pm on Thursday for most parts.
The affected areas are forecast to be struck by some heavy and thundery downpours developing.
Up to 30-50 mm of rain is set to fall in less than 3 hours in the worst-hit areas, though only a few spots would likely see these totals, the national forecastersays.
Temperatures are forecast to drop into the late teens and low twenties across much of the UK by Thursday as the band of rainy weather moves up the country,
Met Office spokeman Oli Claydon told the Mirror temperatures will continue to drop from Thursday.
Conditions should ‘settle’ by the weekend, but remain cooler with ‘chilly’ nights in store, he added.
“For the south west, the change is really starting tomorrow with an area of rain and cloud moving in from the south.”
Mr Claydon added: “For the rest of the country the change really comes in from Thursday when the rain from the south west moves in toward the East and spreads further across England and Wales.
“So for pretty much everywhere, Thursday will be very rainy and it will be cloudy for the majority.”
By the weekend, settled but cooler conditions are set to return to average temperatures expected for this period of September, the spokesman said.
The Met Office said earlier that central and eastern England were the likely areas that could experience a maximum of 30C on Tuesday.
More widely across England and Wales, conditions should reach the mid-to-high 20s, while Scotland and Northern Ireland could see temperatures around 24C to 25C by the end of the day.
Low pressure moving in from the south west on Wednesday was forecast to cool parts of Wales and Northern Ireland slightly, but hot air will remain in central and eastern England and Scotland, bringing highs of 26C to 29C.
Central and eastern parts of England were tipped as most likely” to record an official heatwave across Monday to Wednesday, depending on when the spell of downpours arrive.
September has already beaten August’s highest temperature of 27.2C in the UK, which last happened in 2016.
