The Met Office has issued seven yellow ice warnings across the UK.
The alerts are in place for parts of Scotland, Northern Ireland, Yorkshire and the Humber, lasting from 6pm today until 11am tomorrow.
Forecasters have said the deadly bomb cyclone that sent temperatures plunging in the US over Christmas is causing the unsettled weather in the UK.
It comes after a yellow warning for rain was issued across much of England's south west and southern Wales until 9pm yesterday, alongside further warnings for ice and snow in the Scottish Highlands.
Heavy rain resulted in widespread flooding across southern and central parts of Scotland, bringing travel disruption earlier this week.
Met Office deputy chief meteorologist Helen Caughey said it would be an "unsettled" New Year weekend for much of the UK.
"New Year's Eve for most will be the wetter of the two days, with a number of fronts bringing rain and wind across much of the country," Ms Caughey said.
"The unsettled weather will stay with us into the evening. Much of Scotland will see a largely dry day, with just the odd shower, before a more persistent band of rain and hill snow arrives.
"This will be followed by a more mixed New Year's Day, with Scotland seeing the bulk of the unsettled conditions, with spells of rain, turning to snow over higher ground, continuing to push north.
"While it will be mild across the south, it will remain colder in the north with an ice risk in places here early on Sunday.
"Elsewhere, a drier day is expected, although with some showers, mainly across western areas, ahead of conditions becoming more widely settled into Monday."
The Met Office urged people to monitor their website or app for any further weather warnings over the weekend.
Following up over the next ten days the country could again be facing a heavy blanket of snow.
Exacta Weather forecaster James Madden told the Daily Star: "A Sudden Stratospheric Warming event is now looking even more likely to occur this winter and this could happen as soon as in the next 10 days or so.
"This will mean that the cold air over the Arctic will be given a route to cross our shores. If an SSW does set in icy weather could hit Brits around the middle of January.
“Cold winds blowing into the UK this weekend mean New Year revellers should wrap up to see in 2023.
"We could see some snow hitting parts of Britain around the New Year period, but this is likely to be restricted to the northern half of the country."
