Snow could fall in the UK within DAYS as a forecaster has predicted the exact dates the wintry showers will strike.
A chilly polar blast from Greenland and Iceland is bringing a "growing threat" of flurries arriving as Britain moves into much colder weather.
Weather charts predict snow could fall from the middle of the month with a drop in temperatures expected from November 15.
Six days later on November 21 a cold snap is due in the south of England.
British Weather Services' senior meteorologist Jim Dale said snow could start to fall on the same day.
Mr Dale, who has previously been cautious when predicting snow showers, has revealed that some of the country is likely to see a dusting at the very least.
Maps show snow showers may fall overnight between November 20 and 21 - meaning places that are hit may awake on Monday morning with a delayed commute or school run.
At least 2cm of snow is expected to lay in areas near Newcastle, with this decreasing to 1cm for towns between Manchester and Birmingham.
Some very slight signals also point towards rural and higher land in northern Wales being hit by lighter showers.
Forecasts show this dusting will not melt during the day and will hang around until at least November 22.
Due to this forecast being nearly a fortnight away, maps do not show this weather front lasting into the end of the month or early December, but Mr Dale has shared some of his own key dates.
He told Express.co.uk : "There will be some limited snow in the north west highlands by November 17 in the northern Pennines. It will be just a dusting for now, but a growing threat for Scotland on November 19 and 20.
"It will be colder for all, though, within that period."
But, the snow won't fall nationwide, with most of the country missing the first winter shower of the season.
The south east, central and even some northern parts of England will escape the wrath, but people living in these parts of the country will feel colder as thermometers continue to dip at around this time.
Mr Dale added: "It’ll be notably colder in south east but nothing out of the ordinary for the time of year. This will be caused by the movement south of the jet stream - pulling in moderated polar air from Greenland and Iceland way."
The Met Office's long range forecasts from November 17 through to November 22 are not so clear cut, but they do allude to colder conditions and a change in temperatures in the final weeks before Christmas.
Looking at November 20 to December 15 it says: "A high-pressure system looks likely to settle to the west or northwest of the UK towards the end of the month, bringing more extended periods of dry and settled weather with lighter winds.
"Rain and stronger winds could still be experienced, especially in the far northwest. Into December, eastern areas could see a return to wetter conditions, with occasional frost and overnight fog, that could be slow to clear.
"Temperatures trending towards average for the season, perhaps feeling rather cold."
