It doesn't matter what John Snow says, winter is actually here.
A severe weather alert has been issued by Highways England to drivers as the first significant snow of winter fell across a large swathe of northern England and Scotland and much of northern Europe.
High-level routes across the Pennines were hit by the wave of snow which swept across the north of the country from Tuesday evening.
Authorities took to social media to warn of difficult conditions from Leeds, through the Yorkshire Dales to County Durham.
The Met Office issued a yellow 'Be Aware' warning for much of the west of Scotland, the north-eastern tip of Wales, parts of the North West and North East of England, and down into the Midlands, which was due to expire mid-morning on Wednesday.
Here are pictures from some of the affected places in the UK:
But it seems the Brits haven't got the worst of it yet, as Sweden has experienced heavy snowfalls of up to two feet and temperatures plummeting to below -1.
Imagine being in caught in this!
They have definitely bagged a snow day.
