Brits are set for more than 10 inches of snow and -10C temperatures today while there is also a warning for freezing fog.
Warmer air will be sweeping in over the weekend that will affect the north west of the UK but it will still feel bitterly cold.
And maps from WXCharts show that more than 10 inches of snow could still fall in the west of Scotland on Saturday morning while there will also be one or two inches across the west of the UK.
Freezing fog could bring dangerous driving conditions on Saturday morning which could be so dense that visibility drops to below 100 metres in some places, the Met Office said.
Forecasters have issued a yellow weather warning between 2am and 11am for parts of England, including the Midlands, Yorkshire, Cheshire and much of the South West, and Wales.
Travel delays are likely, while untreated surfaces could become slippery.
The Met Office said: “Freezing fog is expected to develop during Friday night and will be slow to clear in places through Saturday morning.
“Some fog could be quite dense with the visibility falling below 100 metres at times.
“Western England is more likely to see freezing fog persist into late morning and in a few places into the afternoon.”
Overnight temperatures across the country are forecast to hit -2C to -4C in the towns and cities, while it could reach - 7 to -8C in rural spots, according to Met Office meteorologist Ellie Wilson.
While figures of -10C could be recorded in parts of Scotland which have any snow cover.
Met Office forecaster Aidan McGivern said that cloud will move in to the north west of the UK on Saturday morning along with strong winds or gales.
He continued: "Elsewhere eastern Scotland, England and Wales clear skies and light winds and so a widespread frost forming, temperatures as low as -3, -4C fairly widely and -10C to -7C where we have some snow cover."
It comes after temperatures plunged below minus 10C in parts of the UK this week amid snowy and icy conditions.
Drumnadrochit near Inverness in the Highlands hit minus 10.4C in the early hours of Thursday, making it the coldest recorded temperature of the year so far.
Manchester Airport was also forced to close both its runways for a period due to heavy snowfall.
