SNOW is set to hit the UK with the mercury falling below zero as an explosion of Arctic air sweeps across the UK.
The flowery white stuff could drop as early as Thursday, the Met Office has warned.
Forecasters have warned that an Arctic eruption will put Britain on hold as the polar vortex is a “knock off kitter”.
Britain is facing its worst winter storm in 13 years that could dump piles of snow across the country by the end of the month.
And cold weather is about to hit the UK in a matter of days – bringing with it “White Halloween” for some.
According to forecasters, after several days of unstable wet weather and mild temperatures, the mercury will start falling from Thursday.
John Hammond, a former BBC weatherman and WeatherTranding meteorologist, told Online: “There is a slight warming in the stratosphere, which will act to weaken the polar vortex and close it over the next week or two.”
He said it could cause “bouts of cold air blowing from the Arctic” to hit the UK “later in October”.
John said: “After a very mild few days, next weekend there will be a very cold wind from the north, which could bring some snow to the Scottish mountains.
“This cold spell may not last that long, but frost, and eventually snow, will probably come more frequently in our forecasts much earlier.”
The Meteorological Department has confirmed that there is a possibility of snow “on the tops of the mountains of Scotland” this week.
A spokesman said wild weather could turn “sleepy in the snow” and affect until the early hours of Thursday, and last all day until 10 a.m.
In some parts of Wales and Scotland, blankets can be worn until 6 a.m. the following Sunday.
But the southern shoreline could also be gathering dust in the “rare” forecast last seen in 2008.
The Met Office’s long-range forecast said: “Temperatures are falling below average for most, increasing the likelihood of snowfall on higher ground in the north.
“More settled conditions are very likely to develop for some time towards the end of the week with some dry weather for more.
“However, it may become unstable again over the weekend as clouds, rain and strong winds come from the west. The unstable conditions are likely to continue till the end of October.”
