Temperatures are set to plummet as an early icy blast will bring winter forward which could bring snow by mid November.
Forecasters have said parts of England including London could see snow by mid-November and widespread fog will be common.
James Madden, forecaster for Exacta Weather said, “There are likely to be some large flirtations with cold temperatures throughout November.
“Widespread frosts and fog will be a common feature, and the possibility is there of a number of snow events across northern Britain.
“These may even reach as far south as the capital from mid-month onwards.
“November looks like delivering an early taste of extensive winter for many.”
He added, “The cold shots from the back end of autumn are likely to continue into the first month of the meteorological winter.
“Cold is likely to be prevalent through much of the month, with any milder weather being restricted to a cluster of days during the first half of the month.
“Wintry weather and snow will accompany these cold conditions throughout the month too, and some notable snow events will be recorded across some large swathes of the country.
“Widespread and heavy snow showers are increasingly likely through the second half of December.
”It comes as temperatures plunge across the country prompting bookies to slash the odds on the coldest November on record.”
