THE warm spell that Brits have been enjoying over the past few days will be cut short with freezing temperatures to return within 24 hours.
Low conditions are expected in March - but the Met Office dismissed reports of a "snow bomb".
Experts rubbished claims that a massive 270-mile snowstorm is on course to hit parts of Britain this month just weeks after February's 18C warm snap.
A spokesperson said: "There is nothing like that in our immediate forecast, or in our longer 30-day outlook which can be seen on our website homepage."

LONG RANGE FORECAST INTO MARCH – MET OFFICE
The Met Office’s forecast for the first half of March says: “High confidence for this period as local high pressure is likely to give a mostly settled outlook, with any uncertainty existing with respect to the orientation of this high.
“Currently the signal suggest a placement over the south of the UK before transferring to the north later next week.
“This means most areas will stay fine and dry with plenty of sunny spells, and that any spells of rain and stronger winds are most likely to the far north and west of the UK where front incursions are most likely.
“Temperatures are likely to remain around average for this time of year, however a short cold spell may occur near the end of this period.
“Where skies clear overnight frost and fog patches may become prevalent.”
FROSTY START TO TOMORROW
COLD AND BRIGHT WEATHER FORECAST TO WELCOME IN MARCH
Cooler sunny weather is due to settle over the UK in the first week of March following a February of temperature extremes.
The highest and lowest temperatures of the winter were both recorded in February, with a 41.4C difference between the two peaks, according to the Met Office.
The mercury hit -23C (-9.4F) in Braemar, Aberdeenshire, on February 11, and on February 24 it rose to 18.4C (65.12F) in Santon Downham, Suffolk.
Monday, which marks the first day of meteorological springtime, is expected to bring foggy mornings with spells of sunshine breaking through by midday, and average temperatures of around 6C (42.8F) in London.
Northern Ireland and western areas of the UK mainland are set to see the best of the sunshine, which could also bring warmer temperatures in the low teens.
‘DON’T BLOW IT’ EXPERT WARNS
Britons are being warned making the most of warmer weather and sunshine could jeopardise our chances of sticking to the prime minister’s reopening road map.
Speaking to Sky News, professor Calum Semple, an expert in “outbreak” medicine, warned the public to continue sticking to the lockdown rules or we could “blow it”.
Asked whether crowds could cause case numbers to rise again, professor Semple, who sits on the government’s SAGE advisory board, admitted to Sky News: “This is a big worry to us.”
“We’re just not quite there on the road map – we can’t take a short cut with people’s health.”
OUTLOOK FOR THE REST OF THE WEEK
A misty start tomorrow, some lingering through the morning until midday.
Cloud will linger on into the afternoon, but some late sunshine is possible, mainly in south-east England and north-west England.
Staying cloudy on Wednesday with some light showers moving into Wales and the south of England.
SNOW IN MARCH?
Weather charts show a 270-mile ‘snow bomb’ is on course to hit parts of Britain next month – after an 18C warm spell.
WX Charts predicts a band of snow – stretching from Norfolk to Dorset – could blanket some areas.
It would mean Birmingham, parts of the West Midlands and Wales, Gloucestershire, parts of Somerset, Bristol and Dorset, could see the white stuff from March 9.
And the wintry weather could continue into April, with the Met Office saying “a white Easter is more likely than a white Christmas”.
Meteorologist Grahame Madge told SomersetLive: “It’s possible that we could get snow in March.

TOMORROW NIGHT'S FORECAST

Mostly clear across parts of the south-western UK and northern Scotland. An area of drizzle may affect parts of eastern Scotland after midnight.
Light easterly winds.
WEAKEST GULF FREEZE IN 1,000 YEARS
The Gulf Stream that helps warm the UK and northwest Europe is at its weakest in over 1,000 years.
Researchers believe it could lead to more “extreme and intense” winters, adding the slowdown observed in the 20th century is “unprecedented” and likely connected to climate change.
The Gulf Stream is part of a larger “conveyer belt” of ocean currents known as Atlantic Meridional Overturning Circulation and carries warm water from the tip of Florida towards Europe.
Its effect ensures Britain has relatively mild winters and without it experts believe temperatures would be around 5C cooler.
MET OFFICE SHUT DOWN ‘MIND BLOWING’ TIKTOK CLAIM
Scarlett Moffatt has been ridiculed by the Met Office after she shared her so-called “mind-blowing” weather app claim about rainfall.
The 30-year-old TV personality took to TikTok to share her “revelation” about weather apps with half a million of her fans, saying: “I’ve just found out that on the weather app, when it says ’30 percent rain’, I thought that meant ’30 percent chance of rain’.
“It doesn’t mean that, it means that 30 percent of your area will be covered in rain.”
However, a weatherman for the Met Office confirmed Scarlett was in fact wrong. Read more here.
SAHARA DUST BLANKET
Saharan dust will blanket parts of Europe today, according to the BBC weather forecast.
Meteorologist Nick Miller warned “more dust in the air from Africa” will sweep across Europe, starting with Spain on Sunday.
Mr Miller explained today’s weather forecast is dominated by wind, particularly across eastern areas, which would “take some rain and snow into Turkey.
“The odd shower around across southern areas of Greece. Quite windy through Croatia’s Adriatic coast. Those winds could be disruptive.”
“Still, a lot of fine weather through Iberia, though we could see some more dust in the air from Africa, and some wet weather across northern coastal areas of Norway.”
A rather misty or foggy start for all, with the densest fog likely in Northern Ireland, Scotland and northern England. Cloud will clear to sunshine across northern England and Scotland this afternoon, but cloud will linger elsewhere in England. Brighter in the south later.
Gentle easterly winds.
