Britain is set to have a white Christmas this year. Weather experts expect 36 days of snow or ice across the winter months, with harsh temperature lows of -16C.
AccuWeather meteorologist Tyler Roys said: "We'll see full-on cold spells.
"Northern England faces colder-than-normal periods, some of which could affect southern England, and Scotland is forecast a colder than normal winter.
"Given recent past winters' minimum temperatures of -8C to -21C, lows of that level are possible this winter."
Meanwhile, Ladbrokes cut the odds on temperatures falling to -16C whiled the odds on the UK enjoying a white Christmas have fallen from 5/1 to 2/1.
A Ladbrokes spokesman said: "The mercury looks like dropping as fast as the odds in a brutal winter."
Experts say that the weather is due to the melting of the Greenland ice sheet, also feared to be slowing the Gulf Stream, which pushes warm currents towards Britain.
The US Government's National Oceanic and Atmospheric Administration weather department said: "The area of ocean had its coldest January to August in at least 80 years of records."
