A jet stream of icy air from a deadly deep freeze in parts of the US is now blasting towards Britain.
The Met Office shared footage of the jet stream path as it carried the cold air across the Atlantic ocean, predicting it could lead to "unsettled conditions" over the New Year Weekend.
In a weather tweet, it said: "This is partly related to the cold air that has been spreading across North America, helping to strengthen the jet stream and push low-pressure systems across the Atlantic."
It comes as a deadly storm continues to grip parts of the US, with officials saying at least 34 people have been killed from record-breaking low temperatures.
At least 57 Americans also reported being trapped in their cars around New York State, with Buffalo being one of the worst-hit regions.
Those living in Buffalo have resorted to risking their lives as they search for cars buried in the snow.
New York Governor Kathy Hochul said: “This is a war with mother nature, and she has been hitting us with everything she has.
“It is like going to a war zone, and the vehicles along the sides of the roads are shocking.”
Hochul's comments came as she toured the aftermath in Buffalo - her hometown - on Monday, calling the blizzard "one for the ages".
In the UK, a yellow weather warning has been issued for parts of the UK as a band of rain and snow is expected to sweep the country over the course of the day.
The weather warning for snow and ice is in place for parts of Scotland, including Central, Tayside & Fife, over Tuesday afternoon and early evening, according to Met Office forecasting.
With surfaces falling below freezing after dusk, patchy ice is likely to develop on untreated surfaces with the potential for some wash-off of previously treated surfaces where showers fall.
Meanwhile in South East England and Wales, Wednesday will bring a band of rain moving northeastwards, with downpours becoming heavy and persistent.
Affected areas included Cornwall, Devon, Plymouth, Somerset and Torbay as well as Blaenau, Gwent, Bridgend, Caerphilly and Cardiff as well as parts of South West Wales.
Rain will be particularly heavy over the high ground of south Wales and Dartmoor, with a few places likely to get 40 to 60 mm in 9 to 12 hours, before clearing during the afternoon.
Spray and flooding on roads was expected to make journey times longer with flooding of homes and businesses "likely", the Met Office said.
