A POLAR blast is set to send temperatures in the UK plummeting over the coming days, with some parts colder than Iceland.
Here’s the latest on the weather system’s movements and how it will affect different parts of the country.
How is the weather system tracking?
The UK could be blasted with thundersnow – thunder with snow instead of just snow, as wintry weather is set to cause temperatures to plummet as low as -5C.
By daytime today, temperatures are likely to be as low as 4C, with strong winds likely to make it feel even colder.
The same windchill is likely to push swathes of the UK below freezing.
Prevailing easterly winds are set to drive the temperatures down – rivalling even Reykjavik, experts said.
And even the generous forecasts suggest the chilly weather will persist for the best part of two weeks.
What are we likely to see?
WeatherAction’s Piers Corbyn said: “An active low-pressure system will move in from the northwest after the weekend bringing very cold Polar air in from the north.”
Northern regions could see heavy snowfall from next week with stormy conditions triggering outbreaks of thunderstorms.
Meanwhile much of the country could experience bitter winds, snow and the risk of blizzards continuing through until the end of the month at least.
Feeling cold, strongest winds in the north and west.
Met Office forecaster Clare Nasir warns: “Heavy showers will turn to snow on the tops of the mountains, even the tops of the Pennines.”
She said: “It’s a bitterly cold day with a biting wind and heavy showers.”
The showers are coming from the east, with a cold wind, and heading to northern parts of Wales.
Temperatures from 5-8C will feel a lot colder.

Met Office forecaster Steven Keates said temperatures by Wednesday will be affected by “the type of wind that blows through you rather than round you.
“It’s going to be quite a shock to the system.”
The expected snowfall is unlikely to cause any major travel disruption, he added.
Britain was hit by the worst snowstorms in 30 years last winter.
