The cold snap will bring snow, ice, and the rare thundersnow phenomenon, reports The Mirror.
Two weather warnings have been issued in Scotland by the forecaster for January 6 and 7.
One is a snow and ice warning for much of the west coast, islands and southern Scotland.
An additional snow warning for a large band cutting through the centre of the country is also in force.
The cold snap and severe weather could bring about meteorological event called thundersnow.

What is thundersnow?
Thundersnow is a relatively rare phenomenon very much like a thunderstorm, but with snow instead of rain.
Met Office spokesperson Grahame Madge explained why thudersnow happens.
The forecaster suggested that the prospect of thundersnow was caused by the difference in temperature between the ground and the air surrounding it.
He said: ” [Warm air] starts to rise very quickly up through the cold air and that’s what creates the potential for thunderstorms.”
What will the weather be like this week?
The weather warnings issued by the Met Office apply to a large part of Scotland, Northern England, the Midlands and Northern Ireland.
A snow warning is set from 10am to 4pm on Thursday.
The snow and ice weather warning is set to be in place from 8pm on Thursday until 11am on Friday.
As much as 10cm of snow could fall in high parts of Scotland and temperatures in the early hours of Thursday could feel as cold as -4C in Glasgow while commuters in Edinburgh face temperatures as low as -3C.
Mr Madge said: “As conditions get cold tonight, we’re seeing temperatures drop down to freezing quite widely.
“As we get the cold air, that will bring the temperatures right down, we’ve got the weather front coming in from the west and that moisture is going to bump into the cold air and where you get that you will get snow.”
