Weather warnings have been issued across the UK as temperatures are set to plunge to minus degrees with snow and ice on the way.
The mercury is predicted to dip as low as minus 12 Celsius on Saturday night amid reports of a new "Beast from the East" spell of cold weather.
Bookies have slashed the odds on this being the UK's coldest winter yet after the record-breaking "Beast from the East" in 2018.
Snow and ice warnings have been issued – with the Met Office raising the alert level to Yellow on Saturday and Sunday.
Meteorologist Alex Burkill warned The Mirror: "Obviously it's very cold and it's going to stay cold through this week.
"Whilst there will be some wintry hazards around, it's not really until the end of the week until we see any significant snow."
Meanwhile, motoring experts are warning drivers to take extra care amid the freezing conditions.
RAC Breakdown spokesman Simon Williams said: "The message for those who have to drive is to adjust their speed according to the conditions and leave extra stopping distance so 2021 doesn't begin with an unwelcome bump and an insurance claim.
"Snow and ice are by far the toughest driving conditions, so if they can be avoided that's probably the best policy."
The Met Office issued a Yellow weather warning predicting snow and ice on the east of Scotland and England, saying: “Icy patches and hill snow may cause tricky travel conditions in some places.”
The wanting adds: “Some roads and railways likely to be affected with longer journey times by road, bus and train services.”
While the advise the public to take care on untreated surfaces and warn of a risk of injury in the case of people slipping on ice.
A similar warning has been issued for large parts of Wales and the middle of England.
The Yellow warning level there highlights: “Sleet, snow and icy patches may cause some tricky driving conditions this evening.”
Again, roads and railways are likely to be affected – leading to an impact on travel.
By Sunday, the warning is lifted from Wales and central England – but remains in place for eastern Scotland and England.
Overnight temperatures are expected to drop to -12C in Scotland and close to freezing in southern England – bringing an ice-cold start to 2021 for the first week of January.
The snow, ice and freezing conditions raise fears of a second "Beast from the East" weather front landing on the UK to dominate the weather for days.
Forecasters have warned of a "sudden stratospheric warming" above the Arctic that could impact the UK for the next two weeks.
In February 2018, the UK was left shivering in the shadow of an arctic blast named the Beast from the East which saw temperatures drop to -15C.
Winds of 70mph caused blizzards, travel was disrupted, 20 inches of snow were recorded in Gloucestershire while ice brought travel to a halt.
Following the snow and ice forecast for the weekend, the Met Office predicts Monday to Wednesday of next week should feature: “Fine and cold in the north-west of the UK.
“Elsewhere variable cloud cover, brisk northeasterly winds and some wintry showers. Cloud arrives across the north-west on Wednesday, bringing rain and perhaps snowfall here.”
