Snow looks set to be heading to the UK as spring approaches as forecasters predict sudden warming in the Arctic will push cold weather south to Britain. Weather charts show blizzard-like conditions could blanket much of the country with a cold start to March and an intense period of snow lasting for over 18 hours.
According to WX Charts cold fronts will bring icy conditions from Friday March 3 with considerable snow coverage landing on Monday March 6. The most intense flurries are expected between Birmingham and London where 5cm could be falling per hour. A blast of wintry conditions on Monday could lead to prolonged snowfall in places overnight lasting for 18 hours.
The storm will also see intense rains in the south-west and Wales with modeling for precipitation at a rate of 5mm per hour. Earlier this week, Adam Scaife, a long-range forecaster at the Met Office, warned that a sudden stratospheric warming (SSW) could see the winter weather last well into March.
Mr Scaife said: “It’s one of the most dramatic events in the atmosphere and causes the winds to collapse. That is taking place now and it’s drawing in the colder air from Russia and Siberia. It means the month of March is at greater risk of easterly winds and colder weather than it would otherwise be.”
When an SSW occurs it causes usually high cold air to fall in altitude down from the stratosphere and warm, this forces the cold polar air in the troposphere, the layer underneath the stratosphere, to spill out of the Arctic region into temperate areas like the UK .
Atmospheric scientist Dr Simon Lee, co-editor in chief of the Royal Meteorological Society journal ‘Weather’, tweeted that a ‘major sudden stratospheric warming (SSW)’ occurred last week.
If Britons will be shivering in a late winter blast or battling storms will become clearer by the middle of next week, experts predict.
Dr Todd Crawford, meteorologist for The Weather Company, told GB News: “The potential SSW may delay the onset of spring, but climate models are generally cooler/wetter than they have been in recent years, which would be a welcome outcome after the very dry and warm year last year.”
The SSW in February and March 2018 led to major snowstorms and sub-zero temperatures across the UK.
