Meteorologists have also warned temperatures on this side of the Atlantic will you-you between cold and mild through the end of 2022.
Jim Dale, meteorologist for British Weather Services, said Britain could see a knock-on effect of the US freeze while dodging the whiteout.
He said: "America is on the big dipper, but Britain may get a spin on the teacups.
"The UK weather will turn unsettled, and this will be driven by knock-on effects of what is happening across the Atlantic.
"It will turn unsettled between Christmas and New year, and temperatures will ebb and flow between cold and milder."
Freezing Arctic air flooding the United States is clashing with milder air across southern parts of the Continent.
Contrasting air temperatures will drive a super-charged jet stream across the Atlantic on a collision course with Britain.
It will steer a barrage of low-pressure storms systems into the UK through the coming days, according to the Met Office.
Meteorologist Alex Deakin said: "Between Christmas and new year the weather patterns are likely to be quite changeable.
"There is the potential for low-pressure systems to bring wet and windy spells with the potential for brief colder spells in between."
