Sub-zero temperatures and up to four inches of snow are set to hit parts of the UK in a week-long Polar freeze.
Alex Burkill, a spokesman for the Met Office told Mirror Online: “After a calm spell of weather for the past few days we are going to have Polar air instead, followed by a drop in temperatures and colder winds.
“Showers will be falling as sleet and snow – and all areas of the country could be hit.
“In northern England, Northern Ireland and Scotland there will be a greater chance of the snow lying.
“There’s the potential for 10cm snow over Scotland on Tuesday.”
Mr Burkill said temperatures will drop to below freezing across many places in Britain on Tuesday, and in the north they could get to as low as -6C.
He said the Polar air comes from the north west.
A barrage of volatile weather fronts sweep across the UK as a deep area of low pressure starts to edge towards Britain from Greenland.
The wintry bombardment will be transported by the jet stream, which is speeding towards the UK at more than 230mph and will plunge across the country early next week.
It will start to become blustery during the latter part of the weekend with winds increasing in strength and blowing an icy chill across many western parts of the country.
The bitter north-westerly will continue to get stronger, with gale force gusts predicted, carrying masses of cold air over Britain.
Heavy rain will push eastwards turning to snow over higher ground north of the border.
The low will move south-eastwards during the day and there will be a chance of snow falling in most places with the greatest risk of a covering on the hills in north-west England and north Wales.
Temperatures could drop quite sharply and struggle to rise above zero during the day with southern England, London, the Midlands and north-west England all becoming noticeably colder.
Wintry showers are also possible further south and east.
The bitter snap continues until the end of the week at least with little change forecast.
It will stay unsettled with more showers or persistent downpours, some giving snow.
Periods of wet weather will be punctuated by brighter intervals, but it will be windy, with the greatest risk of severe gales across the north and west.
A spokesperson for The Weather Channel said: “The north and west will experience unsettled conditions over the weekend as a deep area of low pressure near Iceland begins to move towards Scotland bringing frontal systems over the British Isles.
“This activity is expected to continue into next week.”
