The bank holiday heatwave comes to an abrupt end today with plunging temperatures and cloud forecast.
As a cold front makes its way south, the mercury is set to plummet by 10 to 12C in parts of the country.
On the east coast, temperatures will drop to 6 to 9C, bringing an end to the above-average temperatures Brits have enjoyed for much of the last few weeks.
The chilly weather is set to come with gusty winds, which the BBC predicts could reach speeds of up to 40 to 45mph in the east and along the English channel.
England’s south west coast will see the warmest of today’s weather, where the mercury will hover in the mid-teens, reaching highs of 17C in Plymouth and 15C in Brighton and Southampton.
It’s also due to be rainy, with the Met Office predicting wintery showers in Scotland, Northern Ireland and the north of England.
Giving the latest forecast, a Met Office spokesman said: “Sunday will be a bit of a shock to the system for many places, feeling much much colder than recent days.
“This process starts through Saturday evening and night as a cold front across northern Scotland drifts south into Northern Ireland and the north of England.
“Behind it the air turns much much colder with wintery showers and a few icy patches, but to the south of it, it’s still relatively mild with temperatures hanging on into double figures.
“On through Sunday this cold front will continue its southward journey across England and Wales, not much rain left on it by this stage but a real dividing line between relatively warm weather hanging on in the south and something a good bit colder for the north.
“In fact temperatures could be 10 to 12 degrees colder in a few spots compared to what we saw on Saturday afternoon.
“The cold weather continues into Monday, but with a few showers along the east coast.
“Elsewhere, lots of dry weather but the wind really will have an edge to it, particularly across the south east corner, feeling just 5 degrees or so in London.”
