'Polar air mass' set to bring snow, hail and thunder
A "polar air mass" sweeping the country is set to bring snow, hail and thunder.
Severe warnings for ice have been issued and forecasters say the cold polar air mass will bring with it a series of showers, mainly across the west of the UK.
The Met Office urged people to take care this weekend as it warned of ice, strong winds and heavy rain.
Parts of the country woke up to snow on Friday and more is expected on higher ground - with one centimetre to three centimetres possible on hills above 200m, while land above 400m could see more than five centimetres.
Temperatures are set to drop and ice is expected across the western side of northern England, Wales and Scotland as well as in large parts of Northern Ireland.
Yellow weather warnings have been issued for those areas.
Forecasters predict the area of low pressure will move north east across southern Britain on Saturday night and Sunday morning, bringing heavy rain and southwesterly gales.
Gusts of 45-55mph could be felt inland, particularly over Sussex and Kent, and winds of up to 65mph are possible in exposed south coastal locations.
Up to 20mm or 30mm of rain could fall within a six to 12-hour period in those areas, and yellow weather warnings for wind and rain have been issued.
Chief forecaster Frank Saunders said: "With lots of varied weather around over the next few days, including ice, strong winds and heavy rain, people should take additional care and keep an eye on any warnings and check the website for the latest details in their area."
The RAC warned motorists to be prepared for the weather.
Spokesman Simon Peevers said: "With the weather set to become increasingly wintry over the weekend, we're urging motorists to make sure they aren't left out in the cold when it comes to dealing with adverse conditions.
"Planning ahead is key, especially if you're going on a long journey, so making sure things like your car's antifreeze/coolant levels and tyre pressures are correct is essential, as well as topping up windscreen washers.
"In addition to vehicle health, it's important that motorists ensure they and their passengers are prepared with supplies of warm clothing, blankets, and some food and water if the worst happens and the vehicle breaks down at the roadside."
