Snow-covered Britain awakens to another warning of icy roads and freezing fog


Britain woke today to a new warning of ice and freezing fog after England experienced its coldest winter night to date, with lows of -11 ° C in the north.

Yellow weather warnings for ice remained in large parts of the UK this morning and only southern parts of Scotland were able to evade freezing conditions, which are said to last until Monday.

England experienced its coldest night of winter to date. Redesdale Camp in Northumberland recorded overnight lows of -11.1 ° C, while Scotland recorded lows of -11.6 ° C in the highlands.

The British have been warned to be careful on icy tracks, which can create difficult driving conditions in much of the UK. Injuries from slips and falls are also a risk in cold blasts from Scandinavia and the Arctic.

Temperatures in the northern parts of the UK are expected to stay as low as -9 ° C this morning. More snow is expected to fall over the Pennines, North York Moors and the Highlands of Wales, according to the Met Office.

Forecasters added that elsewhere it will remain largely dry, although low clouds and freezing fog are expected to hit parts of central and southern England throughout Saturday.

It follows heavy snowfall that hit much of the UK yesterday and wreaked havoc on the roads as cars overturned, ambulance vehicles slid off the road and motorway traffic stalled.

The Met Office warned that some areas in northwest Scotland could be exposed to flooding over the weekend due to heavy rain that is expected to hit the area on Sunday.

Forecaster Greg Dewhurst told MailOnline that freezing conditions from Scandinavia and the Arctic are pushing over the north and northeast of the UK.

The colder weather will last until Monday, when temperatures in the south of England are expected to reach 11 ° C.

He said: “We are seeing generally dry weather all over England but there is a risk of ice stains this morning.

& # 39; Scotland will experience a cold start with sleet and mountain snow to the east. For many, it will be a cold day with temperatures between 2 and 4 ° C across the country. In the northwest, however, it will be milder with temperatures of 7 to 8 ° C. "

The frigid temperatures will persist overnight on Saturday and through Sunday, again anticipating widespread frost and icy sections, along with more patches of freezing fog.

"Overall, the main theme of the weekend is staying cold in fog and icy roads," said Dewhurst.

Heavy snow hit much of the UK on Friday, wreaking havoc on the streets as cars overturned, ambulance vehicles slid off the road and motorway traffic stalled.

The British have been told to remain cautious when venturing into the dangerous conditions brought on Friday by the cold snap. Forecasters have warned that this could be the forerunner of a blanket of snow and high winds from Siberia, as last seen in 2018 with the memorable beast struck from the east.

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

The Durham A1 was brought to a standstill yesterday with motorists suffering hours of traffic jams due to problems during the snow, including a blocked truck.

Spreaders, snow plows and salt spreaders were on the road early Friday morning to make the asphalt as safe as possible. Drivers in the northeast should only take to the road when absolutely necessary as the weather caused 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;

In nearby Otterburn, Northumberland, a truck skidded around a tight corner and crashed through the barriers. It is pictured coming to rest on a steep bank, sloping slightly to one side, while part of its front is damaged.

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 drive 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 for 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;

Will the beast from the east be back? Forecasters note the same "warming of the stratosphere" that caused chaos in 2018

The Beast from the East was the name for the icy winds that came to Great 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 and brought snow across much of the country. The weather in the 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 sliding on ice.

The cold spell was caused by a temperature jump high above the Arctic, which meteorologists call "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 sucked in from the east over the British Isles, resulting in colder temperatures.

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

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.

The cold snap comes from the fact that the same conditions that led to snowstorms three years ago are supposed to re-emerge high up in the atmosphere.

The sudden warming of the stratosphere (SSW) event occurs when the temperature in the stratosphere rises by 50 ° C. This reverses Britain'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. This was the case with the infamous Beast from the East in February 2018, which saw much of the UK hit by travel chaos and school closings in heavy snow.

In the cold, temperatures dropped to -10 ° C in parts of the UK and brought 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 sliding on ice.

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 the UK's weather.

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 "beast from the east" 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 minor deviations may affect when it reaches us. & # 39;
