Forecasters have warned that Britain could see its first snowfall this winter within a matter of days as an Arctic plume looks set to hit the UK.
A band of low pressure is expected to bring icy conditions and freezing temperatures across the next two weeks.
Weather expert James Madden said it is "likely" snow will fall across some parts of Britain as a band of low pressure moves from the north.
The Exacta Weather forecaster said that, from around mid-month onwards, the UK could see "even greater and more significant dumps of snow across higher ground in the north".

He added: "It is now increasingly likely that we will see at least 1-2 notable wintry blasts from late November and into the first half of December, but it may turn milder or much milder later.
"However, a sudden stratospheric warming event from later this month and into December could change that outlook to an even colder and more wintry theme for many parts of the country.
"And would drastically change the overall outlook for December as a whole, particularly, during the second half of the month, and increasing our white Christmas chances significantly under such circumstances."
Temperatures could plummet below 5C on November 11, according to Madden.
