The Met Office has confirmed that 'technically speaking' a white Christmas is very likely.
Temperatures are set to drop to as low as -8C in northern Scotland towards this weekend.
In the eyes of the Met Office, it is officially classed as a white Christmas if a single snowflake falls on the ground in the 24 hours of December 25.
The Scottish Highlands and the northern Pennines are the two areas most likely to see some snow this Christmas.

Some parts of the UK are expected to wake up on Christmas Day with some frost, particularly in northern rural areas.
Met Office deputy chief meteorologist Helen Caughey said: "As we begin Christmas Day wintry showers initially feeding in across the north in the colder air mass would technically make it a white Christmas, as we only need to see a single flake falling.
"Elsewhere, while it is likely at first to be mostly dry there is the potential for rain approaching from the west later on. As this moves east, we may see rain turning to snow, at least over high ground.
"It’s unlikely that we will see widespread or settling snow giving any proper accumulations. Although technically it might be a white Christmas, don’t get your hopes up for a picture-perfect white landscape."
