Fearsome new weather maps show as much 19 inches of snow could soon be dumped on parts of Britain as a seven-day Arctic blast grips the UK.
A yellow weather warning has been issued by the Met Office for parts of the country on Monday and Tuesday.
Snow flurries are predicted across the nation for over a week as Brits brace for one final big chill of winter.
WX Charts' maps illustrate the white stuff is predicted across a number of cities in the including Manchester, Birmingham, Edinburgh, Southampton and Cardiff in around a week.
By March 12, as much as 48cm of snow could be hitting in parts of the Highlands with the mercury potentially dropping to -11C.
According to the charts, the probability of snow falling on Saturday March 11 is around 60 percent in Scotland, while Wales, northern England, and the Midlands all have around a 40 per cent chance.
Wales could experience snow depth of up to 9cm, Birmingham could reach 6cm, and Manchester around 5cm.
Scotland and Northern Ireland could be the first to see snow as early as this weekend.
There will be smaller bursts before then, with yellow weather warnings for the northeast of both Scotland and England with possible travel disruption and icy surfaces.
The south of the country is also expected to see significant snowfall, with three waves on next Thursday, Saturday and Sunday bringing the white stuff to Cardiff, London and East Anglia, according to WX Charts.
The Met Office's senior presenter Aidan McGivern said there were "pretty strong" signals that incoming burst of cold air would bring changes in the weather from the weekend onwards.
The UK Health Security Agency has meanwhile issued a Level 2 Cold Weather Alert for the whole of England as there is now "at least a 60% probability" of severe cold weather, icy conditions or heavy snow next week.
The alert, which will apply between Monday 6 March and midnight on Wednesday 8 March, means health risks could be increased for vulnerable people and disrupt the delivery of NHS services.
Birmingham could be in for a heavy snowfalls next Saturday with some 4cm dropping.
London could be in for a bit more, with the possibility of 6cm settling next Sunday.
The Met Office's Deputy Chief Meteorologist, Chris Almond, said that despite meteorological spring, "there will be a distinctly wintry feel to our weather next week".
He added: "Very cold air will spread across the UK bringing snow showers even to sea level in the north on Monday and these snow showers could spread further south on Tuesday."
The weather is expected to turn over the weekend where it will start to feel colder.
High pressure has been dominating the UK in recent weeks and it is expected to head towards Iceland which could see the northerly winds pushing south across all parts of the country, said Met Office forecaster Alex Deakin.
Addressing the "big question mark" over whether this would result in snowfall, he said: "Here's what we do know about next week - it is very likely to be cold, colder than it is now.
"When you've got that cold air in place and we've got some other things coming together - the position of low pressures - that does increase the chance of some sleet and snow.
“Moisture in air increasing chance of snow, jet stream could also increase wintry showers,” he continued. “Low pressure systems getting involved and they are more likely to inject perhaps a little bit of moisture which combined with the cold air could make things more interesting."
