SNOW go where: Drivers with stuck blocks are trapped on A1 hit by snowstorm


Snow covered large swaths of the country today as the British were warned to remain cautious if they ventured into the dangerous conditions caused by the cold snap.

In the early hours of the morning, the Met Office revised its forecast and only spared the southeast and parts of western Scotland from its yellow weather warnings.

Icy surfaces have already wreaked havoc on the streets this morning and Derbyshire police used a picture of an upside down car to warn other drivers to be careful behind the wheel.

The Durham A1 was brought to a standstill and motorists had to endure hours of traffic jams due to problems caused during the snow, including a truck blocked.

And in Harrogate, Yorkshire, cars and pedestrians have been seen braving blizzard-like conditions as the snow fell on them.

But morning dog walkers took on the wintry weather and trudged through the thick snow that settled as temperatures dropped to -6 ° C.

A romantic picture showed the statue of the Angel of the North at Gateshead, looming over a snow-covered acre of land, when children armed with sleds visited the landmark of the hill.

It comes amid warnings that the memorable beast from the east that wreaked havoc across the country in 2018 and forced schools to close may return.

Temperatures will have a hard time getting above 5 ° C and north of the border they will drop to -6 ° C this morning as forecasters are advised to wrap up warm and be careful if you have to go outside.

Clouds of mist are also expected for parts of the south, while sleet and snow outbreaks have been forecast for the Midlands and parts of the north.

After another freezing night with national temperatures between -6 ° C and only 3 ° C, Saturday will usher in sunnier times with no weather warnings – although it will still be very cold.

Thick clouds over northwestern Scotland sink south over much of Scotland, Northern Ireland and Northern England during the day, causing light rain that can sometimes be wintry.

Although strict instructions to contain the spread of the coronavirus are in place across the UK, with the exception of essential work, drivers have been warned to be careful on the roads.

Drivers in the northeast were told to only get on the road when absolutely necessary as the weather was causing major traffic jams.

Highways England tweeted, “We are currently monitoring heavy snowfall which is causing disruption in the Durham area. Traffic officers and spreaders patrol the area. For delays of 60 minutes on the A1M going south, we advise drivers to only travel if necessary. & # 39;

Thames Valley Police, which covers Berkshire, Buckinghamshire and Oxfordshire, said: “Please be extra careful when driving this morning as some roads may be icy. If you are driving this morning, please completely de-ice your car windows, adapt your driving to the conditions, stay away from vehicles in front and allow extra time to travel. & # 39;

The Surrey Police warned that just because the roads are paved doesn't ensure they are completely ice-free! Drive safely and be aware that black ice is possible on roads. & # 39;

What was the beast from the east?

The Beast from the East was the name for the icy winds that came to Britain from Siberia in late February 2018 and were caused by the temperature jump over the Arctic.

In the cold, temperatures dropped to -10 ° C in parts of the UK, bringing snow across much of the country. The weather in Brecon Beacons National Park was so cold that an entire waterfall was frozen solid.

16 people died in winter-related deaths, including a seven-year-old girl from Loos, Cornwall, who was hit by a car that slid on ice.

Truck drivers who work all night this morning warned others who took to the streets this morning to be careful of freezing conditions.

A Somerset-based distribution company tweeted a picture of snow falling on one of their vehicles and said, “Another cold night with patches of snow across the country! Go carefully out on the street. & # 39;

The traffic cameras in the northeast showed heavy snow and the streets were covered in white stuff.

The same conditions that led to snowstorms three years ago are re-emerging high up in the atmosphere.

The Sudden Warming of the Stratosphere (SSW) event occurs when the temperature in the stratosphere increases by 50 ° C. This "reverses" the UK's wind pattern, from the warmer west in the Atlantic to the east – and into Siberia.

It can take two weeks for the effects of a pregnancy week to be felt. Such was the case with the infamous Beast from the East in February 2018, which saw much of the UK suffer from travel chaos and school closings in heavy snow.

Dr. Richard Hall, an expert on SSWs from Bristol University, said he was loading the dice or guessing the odds in favor of another blast of heavy snow and sub-zero temperatures from Siberia.

A study by experts from the Universities of Bristol, Exeter and Bath shows how dramatic meteorological changes over the North Pole can have serious consequences for UK weather.

What is Sudden Stratospheric Warming?

Severe conditions hit the UK in February 2018 have been dubbed a "cocktail of weather events" by the Met Office.

The cold spell known as "the beast from the east", which also coincided with the arrival of Storm Emma, ​​was caused by a temperature jump high above the Arctic that meteorologists termed "sudden warming of the stratosphere".

The phenomenon that usually leads to cold spells in the UK starts 30 km in the atmosphere of the high altitude jet stream, which normally flows from west to east, bringing relatively warm and humid air from the Atlantic to the UK.

A disturbance hits the jet stream, pushing its waves towards the Arctic and reversing the stream from east to west. As the air over this area is compressed, it starts to heat up.

This creates high pressure over the North Atlantic and blocks the usual mild airflow that flows into the UK from the west.

Instead, colder air is being sucked in from the east over the British Isles, resulting in colder temperatures.

During an SSW, the stratosphere – the layer six to 31 miles above the earth's surface – can increase its temperature by up to 50 ° C within a few days.

This disturbance can travel to the earth's surface through the atmosphere and cause shifts in the jet stream, the fast-moving air currents that cool Europe.

British experts examined 40 episodes of stratosphere warming over the past six decades in the latest study published in the Journal of Geophysical Research.

Dr. Hall said that one SSW is "every two years in three" and one is "at the moment".

In 2018 there was an SSW event two weeks before the & # 39; Beast from the East & # 39; Brought 50 cm of snowfall.

Dr. However, Hall said only two-thirds of SSWs make it to the surface and the current one could "just wear off".

He added: “The main area of ​​impact is over Siberia, where it gets very cold and then extends west towards Europe.

"We're on the verge of it and so slight deviations can affect when it reaches us."
