Brits are set to shiver in five days of snow as an Arctic blast freezes the nation and temperatures plunge.
Forecasters have warned the wintry weather will begin this week and some regions could see snow fall for at least five days.
The looming cold snap will see temperatures drop to minus 11 from next week as freezing conditions look likely to cause travel disruption.
Experts predict that between November 17 and 26 there will be a low risk of wintry showers, but a high chance of frost and fog in the north.
Tyler Ros from AccuWeather said: “The threat for snow between November 17-22 looks to be around normal for the time of the year, which is any accumulating snow is likely to occur in the higher elevations of northern England and Scotland.
“We do have to watch a cold snap that appears to move into eastern Europe early next week.
“If this bleeds westward towards the UK (with the core of the cold remaining in eastern Europe), then the temperatures will be near to slightly below normal during this stretch.”
WXCharts say temperatures could fall to between -7C and -11C from the week of November 23.
Meanwhile, the Met Office has issued a yellow weather warning as heavy fog is likely to sweep across the UK.
The warning area affect South West England, East Midlands, North West England, West Midlands, Yorkshire and Humber and Wales overnight.
Thick fog could cause difficult, possibly dangerous, travel conditions, forecasters have warned.
The warning is in place until 10am on Monday.
On Monday experts predict a clear day for many with rain likely in some areas, before a risk of fog in the evening with the coldest temperatures in the north.
