UK long-range forecast: Ferocious Arctic cold snap to blast Britain with 72 hours of SNOW

Arctic air from the north is expected to plunge southwards towards the end of November and could bring wintry weather to the UK. WxCHARTS’ snow depth forecast shows higher ground in Scotland could have a layer of snow settle over a two to three day period from Thursday, November 19 and Saturday, November 21. The snow probability models also show a 30 to 40 percent chance of snow for much of the following week, across northern parts of the country, as the charts turn blue on these days.

Temperatures are also expected to plunge to freezing lows of 0C in central and western Scotland during this period in November, forecasts suggest.

Northern parts of England including Newcastle and Liverpool may see temperatures fall to single figures of 3C.

And southern regions including London and Surrey could also shiver with chilly lows of 4C.

BBC Weather’s long-range forecast between Monday, November 23 and Sunday, December 6, predicted wintry shows in the north and west.

The forecast said: “Although it will often be quite mild, the low pressure track will occasionally dip southwards over central Europe towards the Alps and Italy.

“This will pull in winds from the north or northwest into the UK, leading to colder snaps, with night frosts and squally wintry showers.

“The greatest likelihood of snowfall will be over the hills in the north and west, especially in Scotland.

“A couple of these short cold snaps might be expected to occur during the course of this two week period.

“But they will not last more than about two or three days, before the mild westerlies return.”

The Met Office added wintry conditions could strike higher ground in northern regions in December too.

The long-range forecast between Thursday, November 26 and Thursday, December 10, said: “The end of November is likely to be generally settled with high pressure set to dominate, with settled conditions expected to be more prolonged in central and southeastern areas.

“However, occasional unsettled periods do remain possible, although likely to be short-lived and mostly affecting northwestern areas of the UK.

“Temperatures are probably remaining around average at first, before possibly turning colder than average into December with increased risk of overnight frosts.

“The chance of wintry precipitation could also be increasing into December, notably for northern higher ground.”

Netweather’s long-range forecast between Monday, November 30 and Tuesday, December 8, warned of wintry showers in certain regions of the UK.

It said: “With pressure falling over Scandinavia there is potential for one or two short-lived northerly blasts during this period, possibly bringing wintry showers to northern and eastern regions, mainly near north-facing coasts.

“But a prolonged spell of northerly winds looks unlikely.

“Otherwise we can expect a continued pattern of westerly winds in the north and high pressure in the south, but with the westerlies tending to take hold more generally towards the end of this period.

“Mean temperatures will again be close to or slightly below normal in parts of the south, but central and northern parts of the UK will again be warmer than average.

“Rainfall totals are expected to be above normal in northwest Scotland and near normal in southwest Scotland, northwest England and the west of Northern Ireland, but staying below normal in most other parts of the country.”
