Britain is about to be hit by freezing temperatures and high winds as a “polar vortex” brings a 10-day Arctic blast.
The Met Office warned last night that that up to four inches of snow could fall over high ground in some parts of the country tomorrow.
Forecasters have warned to brace for a “big change” as icy winds sweep in from Russia and the Arctic region.
Thermometers in parts will nosedive to -10C (14F) overnight by the end of the week bringing harsh frosts and icy roads.
Wind changes high in the atmosphere are being blamed for the colder weather triggered a Sudden Stratospheric Warming (SSW) event at the end of January.
The phenomenon affects air circulating the North Pole causing it to swoop southwards or ‘displace’ over Europe and the UK.
