Exact date UK faces being pummelled by 21cm of snow in November blast

The exact day as much as eight inches of snow could fall on Britain this week has emerged in new maps and charts. WX Charts, which uses Met Desk data, shows flurries of the white stuff sweeping the country as we head into the latter stages of November.

The maps, projected this weekend, show as much as 20cm or 21cm could accumulate at times over the coming days. Friday November 29 and Saturday November 30 show Inverness and swathes of the Scottish Highlands, as well as Cumbria and Northumberland in England, facing a huge dumping.

The Met Office forecast for November 21 to November 30 explains: "Cold or very cold conditions are expected across most if not all parts of the UK early in this period, with wintry showers affecting in particular northern parts and exposed coastal districts, although it may well be largely sunny inland.

"Overnight frost will be widespread and occasionally strong winds will result in significant wind chill. However, there is an increasing chance through the first weekend and into the following week of more organised areas of rain, snow and strong winds affecting many areas, this probably also associated with milder temperatures, at least in the south.

"Later in the period, conditions remain uncertain, but it is most likely to remain mostly unsettled with further spells of rain and snow." The Met Office has also issued a secondary forecast, spanning the end of the month from December 1 into the middle portion of the final month of the year.

"Signals vary in prevailing weather patterns through early December. In general, there looks like a trend towards drier and more settled conditions, with high pressure potentially being the more dominant influence over the UK. However. there is also a chance of more changeable weather patterns, which would see Atlantic weather systems periodically move across the country. These will bring some wetter and windier interludes with a risk of some snow, especially for hills in the north. Temperatures generally close to average, perhaps a little above at times, especially in the south," it said.
