Britain is preparing for a monstrous winter storm that threatens to cover parts of the country with snow up to six inches.
The potentially life-threatening storm is hit in just over a week with heavy snow and extreme cold, raising fears of travel chaos that could affect millions of Britons.
The new weather maps show the meteorological system that crosses most of the United Kingdom, from the Scottish Highlands to the north to East Anglia, the Midlands and the south-east coast of England.
The threat has been announced as continental Europe is battered by relentless snowstorms that have killed up to 20 people so far and generated devastating avalanches.
Here in the UK, Met Office predicts a mild climate in the next five days, saying it will be mostly cloudy and windy with sometimes rain.
It will be colder after the next week with periods of winter showers, snow and frost.
From then on, some forecasts warn the British to prepare for a long cold wave with the first major snowstorms of the season.
The Met Office said it can not rule out a repeat of the "Beast from the East" of February 2018, which caused chaos with extreme cold and heavy snow that trapped drivers on motorways at night , entrenched flights and schools forced to close for days.
A weather map from Wxcharts shows up to 5 cm of snow is possible in North Wales and Scotland by next Friday, and up to 1 cm on a higher ground in the Midlands as the temperatures begin to slip.
Approximately 1-2 cm of snow is possible through East Anglia, parts of the Midlands of Greater London and Kent by 23 January.
Snow is also possible in parts of Cornwall and Devon and Northern Ireland in the next seven to 10 days.
The maps on most of the United Kingdom will see snowfall on 24 and 25 January
The system will extend from the Scottish Highlands to the coast south-east of England.  Some places in the Lake District in the north of England could see up to six inches (16 cm) of snow, while Yorkshire could be hit by about 2.3 inches (6 cm), reports the Express.
In its latest long-term update, the Met Office said there are signs that the colder winter weather, resulting from a sudden stratospheric warming, is coming to the UK.
Warming began around December 22 and about 18 miles above the North Pole reversed from west to east around New Year, he said.
As a result of the sudden warming, the Met Office said, the main stratospheric polar vortex split and has been moved across the Atlantic and Europe – a type of scheme normally seen in the spring.  Five-day forecast for Met Office  Saturday
