UK long-range forecast: Arctic weather BOMB to smash Britain with winter freeze – new maps

The UK is expected to be blasted with cold air from the north, including Greenland and Scandinavia, during the end of November. La Nina could also play a part in wintry conditions arriving as cooler than average sea surface temperatures hit the Pacific Ocean this month. Scotland is likely to get a layer of snow on higher ground during the middle of the month, the latest snow depth maps from WXCHARTS show.

Temperatures could also hit 0C in central and eastern parts of Scotland, while Liverpool is also blasted with freezing lows.

Southern regions including London and Kent could also shiver in single figures of 2C as the “northerly plunge” heads further down.

The BBC’s long-range forecast between Tuesday, November 17 and Sunday, November 29, said: “In some of our recent updates, we have been mentioning the prospect of some cold northerly plunges occurring as we head deeper into autumn.

“With a La Nina event ongoing in the Pacific (a vast area of cooler than normal sea surface temperatures over the central and eastern tropical Pacific ocean), then the UK can often see an increase in the frequency of northerly winds in late autumn and early winter.

“But the latest forecast computer models are very opposed with regards to how the second half of the month will play out and this reduces the confidence in the forecast. In this situation we have to look for trends in the individual models over their last few updates.

“We also have to bear mind how skilful they tend to be at predicting certain weather patterns correctly, based on their past performance.

“Our preference remains for there to be more extensive high pressure than we have seen for a few weeks over the north Atlantic and up across Iceland and Greenland.

“This help to steer Atlantic low pressure systems southwards over Scandinavia and eastern Europe, while pulling down colder air from the Arctic towards the UK.

“This increases the likelihood for some frosty nights, cold day and the potential for wintry showers.”

The Met Office also forecasts cold air sweeping across the UK between Friday, November 6 and Sunday, November 15.

The long-range forecast said: “Conditions across the UK are likely to become much more settled and drier this week, but colder.

“Friday will be dry and bright for most although there is a risk of rain and drizzle in the far north. Except for the far north, night frost is likely along with some overnight fog, lasting into in the morning.

“Next weekend, bands of rain will probably start edging up from the south accompanied by milder but murky conditions at times.

“Through the following week into mid November, further areas of rain and sometimes windier conditions may move north across the UK.”

Netweather’s long range forecast for Monday, November 16 and Tuesday, November 24, predicted snow to fall on higher ground.

The forecast said: “Pressure will tend to fall to the north of Britain during this period bringing increasingly unsettled weather.

“Winds will again tend to be west to north-westerly early in this period, with temperatures generally a bit below the seasonal average, with potential for snow on high ground, but probably only rain at low levels.

“There are hints that towards the end of this period it may turn milder with a west to south-westerly type and lowest pressure heading towards Iceland rather than Scandinavia, but confidence in this is low at this range.

“Rainfall totals are thus expected to be above normal over much of the UK during this period, with temperatures coming out near to slightly below normal, though there is some uncertainty over this, depending on the extent of any milder weather late in the period

“Sunshine totals will tend to be above normal early in the period, trending below normal later on, so overall most of the UK will end up with near or slightly above average sunshine.”
