Snow is expected to hit Britain with -11C temperatures forecast in a matter of days.
The poignant Remembrance Sunday commemorations are expected to see bright spells and mild weather across the UK, but freezing temperatures are on their way.
The mercury will hit 14C, with mild spells dominating the weather system this weekend.
Midweek, however, will see a colder chill sweeping in and snow expected to arrive in Scotland first.
Weather maps predict snow may land in the northwest of Scotland by November 17, reports the Express.
Between November 17 and 26 a low risk of wintry showers is expected, but it comes with a high chance of frost and fog in the north.
The “risk” of snow and ice, with spells or rain and strong winds, begins on November 27.
And high pressure in the south and southwest will make fog and frost likely overnight
There is a 50 per cent chance that Scotland will be covered in snow throughout November, but Northern Ireland, Wales and parts of England are also under threat.
WXCharts say temperatures could fall to between -7C and -11C from the week of November 23.
Tyler Ros, AccuWeather meteorologist told the Express: “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.”
Tomasz Schafernaker of BBC weather added: “Some sunny spells but generally speaking there is a large amount of cloud on the way. It is going to be mild and a particularly mild morning, way above the average for the time of the year.
“Sunshine developing across central parts of the UK and some areas being quite sunny but either side of that in the east and the west a fair bit of cloud, really mild 14C in the south around 12-13C in the north.”
“For the vast majority of us a dry day and again sunny spells possible almost anywhere on Remembrance Sunday.”
