The UK looks set for 132 hours of snow, turning weather maps purple as temperatures plunge below freezing.
Maps generated on Saturday (November 9) show snow across northern Scotland, around the Scottish Borders and south of Newcastle at 6am on Sunday, November 17.
According to WX Charts, it spreads down North East coastal regions and into parts of the Midlands by 6pm the same day.
Snow looks set to cover most of Scotland, the North of England and the Midlands, with the white stuff even appearing as far south as Hampshire by midday on Monday, November 18.
A mix of snow and rain covers almost all of Scotland and England by 12pm on November 19, though Wales and South West England stay largely free of snow, WX Charts’ maps show.
But by midday the following day, snow spread westwards across Wales, Somerset and Devon, with the picture looking largely the same until it begins to clear at around 6pm on Friday, November 22, according to WX Charts.
While snow looks set to fall for 132 hours, it appears it won’t be very thick on the ground, with most areas seeing depths of just 1cm.
However, if the maps prove to be accurate this far out, some northern parts of the UK could see depths of 7cm, particularly in central Scotland and the Scottish Borders.
The maps show that major cities, including Aberdeen, Edinburgh, Newcastle, Birmingham, Cardiff, and London, are likely to experience snow between November 17 and 22.
Temperatures may plunge as low as -7C in northern Scotland by midday on November 17, with much of the rest of the UK at 0C or slightly higher.
The mercury then begins to steadily rise into single digits from November 21 onwards, according to WX Charts’ weather maps.
Snow may appear on WX Charts’ maps, but it doesn’t appear in the Met Office’s long-range weather forecast for November 14-23.
The Southwest has the greatest chance of remaining dry, with temperatures around average, although the Northwest may be mild, while the Southeast could be below average, according to the Met Office.
High pressure may decline westwards, meaning many parts of the UK will likely become unsettled, with the North and East “probably” seeing the most frequent spells of rain and showers.
The Met Office’s long-range forecast concludes, “This also increases the likelihood of a spell of northerly winds and colder conditions.”
