ICY PLUNGE: Met Office warning as polar vortex set to bring coldest winter for 35 YEARS
It blames the coming deep freeze on disruptions to the polar vortex wind, which will force it to divert south from the Arctic circle and bring freezing winds to Britain.
The last time this phenomenon happened, in 2010, temperatures in rural parts of the country plunged to a bone-chilling -16C.
In its long-range forecast the Met Office said: “Prediction systems indicate a high chance the polar vortex will be disrupted. Such a pattern would bring cold air to the UK.
“As a result, our outlook suggests an increased risk of below average temperatures during the period.
“This is associated with an increased risk of cold weather impacts in this early part of the winter.”
