The Met Office has issued warnings for northern parts of the UK.
Snow, ice and heavy winds are expected on Tuesday, with temperatures plunging across northern England and Scotland.
'Thundersnow' - when snow is accompanied by thunder - is also a possibility and forecasters say it could be accompanied by lightning.
Most Brits are familiar with normal snowy conditions in winter but what is thundersnow?
Here we take a look in more detail.
What causes thundersnow and how rare is it?
The rare phenomenon occurs when thunderstorms - which are much more common in summer months - form in wintry conditions.
If the weather is cold the rain associated with a thunderstorm can then fall as snow and thus is called thundersnow.
Eleanor Bell, principal meteorologist of The Weather Channel, said: “There needs to be an upward motion for the thunder to develop, warmer air trying to rise under colder air.
“It is less common than normal thunderstorms because it occurs in the colder months of the year when the air close to the ground is cold enough to produce snow.”
Will you hear thunder?
The Met Office says thundersnow is often very atmospheric but the snow dampens the sound of thunder.
Will you see lightning?
When thundersnow occurs at night the lightning seems brighter because the lightning reflects off the snowflakes.
Is it dangerous?
It produces heavy snowfall rates of up to 5cm to 10cm per hour.
It can severely limit visibility when travelling.
