Brits are facing a "double-barrelled" storm as warnings are raised of a return to autumn weather.
Forecasters say the spring-like conditions of recent days are set to end “abruptly” this week.
They say people will be kept “on their toes” as stormy conditions and gale-force winds sweep in across the country.
Millions of people have been making the most of the slightly warmer weather in recent days, hitting parks and beaches across the country.
But Jim Dale, a meteorologist for British Weather Services, said there will be a “fairly major system” from Tuesday.
A warning may have to be issued, he told the Express.
He said: “We are expecting severe gale-force gusts in exposed regions later on Tuesday and into Wednesday.
“This system, which is a double-barrelled low-pressure organisation, has got some venom and is going to keep people on their toes.
“It is safe to say the tranquillity we have enjoyed through the start of the month is about to come to an abrupt end.”
The Met Office said it will turn cold on Sunday night, with showery rain spreading across the north which will be heaviest across Scotland.
Forecasters say the UK will endure “unsettled” weather midweek, with spells of rain and strong winds on Wednesday.
Meteorologist Aiden McGivern told the Sun: “We are looking at a return to autumn with low pressure in charge, and that will bring a return of wet and windy weather.
“It’s a messy transition from high pressure to low pressure."
The warnings follow claims an icy deep freeze is on the way, with sub-zero temperatures and wide-spread snow reported to hit in the coming weeks.
Brits have been told a ‘white Easter’ could even be on the way.
And spring 2021 is likely to be the coldest spring for more than three years.
The plummeting temperature can be put down to a 500 mile-wide Scandinavian surge which could make the country colder than Iceland.
