This week has seen a number of weather warnings issued, including amber snow warnings, as two air masses clash over the UK bringing potentially disruptive weather
The UK’s weather has become a “tale of two halves” as a cold blast sets in today and temperatures tumble down to -13.8C.
After a few weeks of milder than average temperature for much of the country, a cold bloc of Arctic air swept down from the north. It brought with it freezing temperatures, snow and ice, a number of severe and even amber weather warnings were put in place by the Met Office.
They cautioned that snow could be potentially disruptive as it’s set to last until Saturday in places. Speaking to the Mirror, a spokesperson for the Met Office described the weather as a “tale of two halves” as different parts of the UK are influenced by different blocs of air.
The swathe of warnings have been caused by conflicting blocs of air. One, a cold Arctic bloc, sweeping down from the north, and the other, a milder south-westerly bloc, coming in from the Atlantic ocean. As the cold Arctic air squats across the northern half of the UK, it has caused temperatures to plummet well below freezing with widespread frost. In Altnaharra, temperatures tumbled all the way down to -13.8C overnight.
But in complete contrast, parts of the southern UK spent the night, and even parts of today, in unseasonably mild temperatures. Parts of Plymouth only got down to 11.9C overnight- almost 20C warmer than the parts of Scotland gripped by a widespread frost.
Amidst this huge gulf in weather for different parts of the UK, areas in north Wales, the Peak District and Pennines got hit by snow today. Jason Kelly, the Met Office Chief Meteorologist, said: “Cold across most areas away from the south the UK, will be met by moisture-laden air spreading from the south. Where milder air encounters cold air, rain, sleet and snow will develop, bringing the risk of 2-5cm of snow in places, whilst some other areas see little or no snow.
“Over higher ground 5-10cm is likely, while locations above 200m within the Amber warning areas could see up to 25cm of snowfall. Snow here could drift in strong to gale force easterly winds.
“As the milder air from the south gradually pushes northwards the focus for wintry hazards also shifts northward with warnings issued for Scotland.”
Whilst, towards the weekend, temperatures will even out more, growing warmer in Scotland, and cooler in the south, into next week conditions are set to diverge once more.
Met Office spokesperson Oli Claydon told the Mirror: “As we go into next week and through next week a high pressure is expected to build to the east and south east of the UK. This then starts to set up a bit of a north west south east split across the UK with high pressure to the south east with more settled and benign conditions, but more unsettled weather through to the NW bringing more frequent wet windy spells.”
