Snow warning: -10C Arctic hell will crush Britain -Alarm bells ring for NEW Beast from the East | Weather | News

Meteorologists have been keeping a nervous eye on the atmosphere above the North Pole after temperatures started to rise last month. They fear it is now powerful enough to split the polar vortex – the air dome above the Arctic – disrupting the weather across Europe and America.

Meanwhile, UK forecasters have been sounding the alarm for an eastern outburst threatening sub-zero temperatures and snow this month.

A sudden stratospheric warming (SSW) four years ago almost to the day triggered the infamous beast from the east of 2018 that buried Britain underfoot in snow for weeks.

James Madden, forecaster for Exacta Weather, said: “Sudden stratospheric warming could impact water vapor and our weather, driving an easterly weather pattern into early spring.

“Any resumption of cold weather is likely to be short-lived until early spring, as an SSW event could bring a return to winter well into March.

“We do, however, need to allow for some deviations in the exact timings of this event.”

Experts warn that imminent stratospheric warming appears powerful enough to split the core of the polar vortex.

Previous events have been linked to extremely cold weather in the UK as Arctic Air flows south across northern Europe.

Andrej Flis of Severe Weather Europe said monitoring the polar vortex over the next few days would be “crucial”.

He said: “The polar vortex is facing a stratospheric warming event, which will be strong enough to cause a temporary split in its outer core.

“Meanwhile, the same dynamics will also shape the weather circulation in the lower levels.

“The Polar Vortex is a powerful short to medium term weather engine during the cold season.

“For this reason, it is crucial to monitor activity above the stratosphere.

“In the next few days, the Polar Vortex will experience a disruptive first wave of warming, also influencing the weather.”

Netweather’s March forecast agrees that a weakening polar vortex threatens the risk of a cold easterly outburst this month.

However, the weather is expected to be marred by unstable Atlantic conditions at the start of the month.

Netweather forecaster Nick Finnis said: “Recent model forecasts indeed reflect a…pattern shift in the troposphere, with a weakening of the recently strong tropospheric polar vortex…leading to the splitting of the polar vortex in the troposphere, with one vortex over Greenland the other over Siberia.

“Frontal systems will try to cross the UK at times in the first week bringing rain at times but the ridges appear to be building across the UK in the first weekend before building further north east of Scandinavia during the second week of March.

“The north-easterly high possibly extending far enough west to allow a brief cold easterly flow over the UK, although confidence is fifty-fifty on what is past.”

It comes as government meteorologists confirm the eighth warmest winter on record with February temperatures around 2C above average in England and Wales.

Dr Tim Legg of the Met Office’s National Climate Information Center said: ‘The relative drama of the latter part of February belies the fact that the majority of the winter has been fairly mild in terms of weather events, with relatively few frosts and little general winter weather. .

“However, once again we saw a warmer than average winter, with average temperatures for the season among the ten warmest since records began.”

Meanwhile, a low pressure system passing over Greenland and Iceland this evening threatens further heavy rains through the end of the week.

Jim Dale, meteorologist for the UK Meteorological Service, said: “Another frontal system is coming into contact with milder air and colder air.

“This will bring the risk of more heavy rains through Thursday, much of which will affect areas already affected by heavy rains in recent weeks.

“There will be a risk of snow looking further north, although the main risk will come from rain.”
