Britain has been blanketed by snow as the Met Office warns of icy conditions.
It comes as a rugby match in Exeter was forced to stop after a freak hail storm made it impossible for players to see.
Snow flurries have covered regions of the country including Derbyshire and Leicestershire as temperatures plunged to as cold as -8C last night.
The Met Office warning comes after police issued alerts to motorists in some areas of northern England as snowfalls and flooding left vehicles stranded.
North Yorkshire Police said the A170 at Sutton Bank, Thirsk, was closed overnight and reported problems on the A59 Harrogate to Skipton Road, in the Yorkshire Dales.
Snow was also reported on the M62 at its highest point between Greater Manchester and West Yorkshire.
There were also reports of a covering of snow in Cumbria and over on the east coast near Scarborough.
Meanwhile in Exeter, the bizarre weather phenomenon happened at around 2.30pm and saw hail so thick it reduced visibility.
It was so bad it even forced the Exeter Chiefs vs Sale Sharks rugby match at Sandy Park to be temporarily postponed.
A spectator at the game described it as "deafeningly loud" and "pretty intense".
They told Devon Live: "It was very heavy, tough to see other side of the ground. The noise was deafening as it hit the roof of the grandstand. It came out of nowhere.
"It started as a rain shower and with in 2-3 minutes it was very heavy hail."
Met Office forecaster Craig Snell said: “There are warnings in place for ice and hill snow for north Wales, north England and Scotland throughout the weekend, so roads could be extremely slippery.
“There could be up to three centimetres of snow falling, particularly on hills above 300 metres in Scotland and The Pennines.
“The rest of the country will also feel cold as bitter winds and rain showers continue.
“Temperatures could dip to around 2-4C in the south this evening.”
In Leicestershire a driver was stranded in floodwater and had to be rescued from his car in the early hours of Saturday morning, Sky News reports.
His car remains partially submerged on Watery Gate Lane, Thurlaston, a road notorious for flooding which has seen at least 19 people in need of rescuing between 2014 and 2018.
St Ives in Cambridgeshire was surrounded by flood water today as the River Great Ouse bursted its banks following a few days of heavy rain.
Further showers are forecast for much of the UK tonight.
Temperatures are expected to fall to -5C in the Scottish Highlands overnight due to a freezing spell coming in from the Arctic.
There is potential for more snow ahead, according to Met Office meteorologist Greg Dewhurst.
Mr Dewhurst said: “Anyone who is out Christmas shopping will have to wrap up warmly.
“Over the high ground of northern England and Scotland, some places may have a covering of snow.
“Temperatures for most places will be between 3C (37.4F) and 7C (44.6F), with maximum temperatures of 10C (50F) in the South East where the best of the sunshine will be.
“We are also looking at wind gusts of 35 to 40mph.”
