Weather maps suggest a giant wall of snow and rain will cover the UK from top to bottom as the mercury drops below freezing.
Maps from WXcharts show areas from Wick to Birmingham turning blue and purple with rainfall up to 55mm lashing a number of cities.
Temperature levels will swing between -1 to -3C as Brits brace for a big winter freeze.
The weather maps show the possibility of rain and snowfall on December 4 in areas, such as Inverness, Edinburgh, Birmingham, Wick, Fort William and Glasgow.
A storm front stretching from the north of Scotland to the south coast of England will bring heavy snow for some, and rain for others.
The Met Office long-range forecast between November 27 and December 6 stated: “Most likely starting dry, settled and colder than average across the UK with widespread morning frost.
“Outbreaks of rain and slightly milder conditions are however soon likely to arrive into the northwest, spreading southeast to many parts.
“The early part of next week is most likely to be characterised by light winds and a mixture of wetter, cloudier conditions and colder, brighter and drier conditions, before winds from a broadly northwesterly direction become more established.”
They added: “These (will lead) to periods of wet or showery weather focussed in the northwest of the UK, and largely dry weather elsewhere.
“Temperatures overall are most likely to be just a little colder than average, with only a very small chance of something much colder and wintry developing from mid to late next week.”
The snow will continue to hit areas located in the north of Scotland and will fall up to 26cm on December 8, maps suggest.
