How long is the cold weather expected to last - and what is causing it?
Drivers were urged to take care as weather conditions made for dangerous roads
The UK shivered through another cold night on Wednesday, with some areas approaching near record-low temperatures.
According to provisional recordings by the Met Office, the mercury fell to as low as minus 13C in Glen Ogle, central Scotland, while minus 11C was recorded at Tulloch Bridge in the Scottish Highlands.
The last time temperatures dropped that low was in January 2010, when minus 22.3C was recorded.
ITV Weather Presenter Lucy Verasamy answers the key questions surrounding the cold weather and how long it is expected to last for.
What is causing the recent cold weather/ 'arctic plunge'? Cold Arctic air has swept across us from the north in recent days.
Temperatures have plunged below freezing in the last few nights in nearly all locations with widespread sever frosts, ice and frozen ground.
Temperatures have been barely above freezing by day keeping it bitterly cold. Where are the warnings in place? There's yellow warnings in place for snow and ice for parts of Scotland. The Northern Isles of Scotland will have blizzards and heavy snow - and here there’s an amber warning for snow and ice. Many places are prone to icy slippery conditions overnight and in daytime hours - with or without weather warnings - the risk remains. There will also be the added hazard of freezing fog forming in places. How cold is it?
Last night and Tuesday night were the coldest of the winter season so far with a drop of near -14C in remote parts of Scotland and near -10C and below for some rural spots of England, the coldest spots named as Sharp in Cumbria and Benson in Oxfordshire.
Expect another deep freeze tonight with another widespread, serious frost, ice and temperatures dipping to -10C lower across remote, areas of Scotland and England making it as cold as last night.
It'll stay freezing, frosty and icy for much of tomorrow morning - and for some, all day.
Which parts of the country could see snow? Parts of northern Scotland will continue to see fresh falls of snow with blustery winds and blizzard conditions with more wintry weather to come in these locations tonight and into tomorrow. Icy conditions and freezing fog will be hazards to be aware of.
How long will the cold weather last?
The cold Arctic air remains with us this week - with very low temperatures by day and by night.
Temperatures will be either way below or close to freezing and all of us prone to widespread harsh overnight frosts and frozen ground lasting into the daylight hours. There will be biting and bitter northerly winds enhancing the cold feel across exposed coastlines of Scotland. Come the latter stages of the weekend a switch in the wind direction will mean weather systems approach from the mid Atlantic introducing less cold air - temperatures will soon recover along with windy, wet weather into Sunday and the new week.
Any lying snow will thaw rapidly - leading to standing and excess water in places.
