A lethal cold snap from the North Pole is set to grip Britain, weather experts have warned.
It’s feared the horrific weather will bring heavy bouts of snow and cause travel chaos, with temperatures plunging as low as -11C.
Monday will bring the first big Autumn freeze with motorists waking to find frozen windscreens after temperatures fell to -4C overnight.
And the forecasters say parts of the north could have snow on the hills within days.
But Arctic winds later this year are expected to deliver Britain’s coldest winter since the bitter 2012-13 freeze.
December and January are both forecast to be colder than normal, with all areas of the UK, including the south, being affected.
Five years ago temperatures plunged as low as -14C in the same two months.
Snow and ice caused mayhem on roads and railways and deaths due to cold weather soared to around 300-a-day.
Since then the UK has experienced a series of mild winters but that seems certain to change.
Todd Crawford, chief meteorologist at The Weather Company, said: “We expect the coldest winter in the UK since 2012-13.
“We expect extended spells with a ridge of pressure in the North Atlantic, especially in early winter.
“This forces the jet stream up to the Arctic and back down into Europe, releasing Arctic high pressure from near the Pole directly into northern Europe, with colder-than-normal temperatures.”
AccuWeather senior meteorologist Alan Reppert said: “Snow and ice will be a much higher threat this winter, and could affect London.
“There is a higher-than-normal potential for temperatures below -10C further north, and also cold temperatures further south.”
The first chill will be felt this week with the possibility of snow over high ground.
But mid-November will bring a short break from the cold before the expected big freeze.
Helen Roberts, a Met Office forecaster, said it will feel chilly today (Monday) and tomorrow (Tuesday), with temperatures reaching a maximum of 12C.
But by the middle of the week temperatures will start rising towards the mid-teens.
