A snow warning has been issued for parts of the UK as forecasters anticipate up to four to six inches to fall across parts of the nation.
The warning comes as an arctic blast, dubbed the 'Troll of Trondheim', is due sweep south across the UK bringing freezing temperatures as the week draws to a close.
Many Brits woke up to frosty and potentially icy conditions on Thursday after the mercury dropped below 0C in large parts of the country overnight, including many major cities.
Biting cold weather of -4C was recorded in Manchester in the early hours, while parts of the capital also experienced chilly lows of -2C.
The yellow warning for snow is in place for North Highland, Moray and Aberdeenshire and was in place until 12pm on Sunday.
Meanwhile, a yellow weather warning for ice has been issued on Thursday, covering much of the UK.
The warning was in place for most of Wales, barring parts of the south around Cardiff, and parts of the South West and the east coast of England, as well as most of Northern Ireland.
The Met Office is warned snowfall could cause disruption to travel, with drifting and blizzard conditions possible on hill routes and ice likely to form on untreated areas.
Some roads and railways were likely to be affected with longer journey times by road, bus and train services, the forecaster said..
It also warned of the possibility of injuries from slips and falls on icy surfaces.
The bloc of freezing weather was named as such because it swept in from Norway, where the city of Trondheim is.
Scotland will see the worst of the weather but in Wales the temperature will remain slightly warmer than the rest of the UK, staying as high as 3C overnight.
The very worst affected areas in parts of rural Scotland could see -10C or colder, whilst parts of rural England get as cold as -6C. This could be repeated again on other nights this week.
Chief Meteorologist Steve Willington said: “Yellow National Severe Weather Warning is for ice and snow have been issued for parts of Scotland, Northern Ireland, Wales and the east coast and South West England.
"Showers will turn more wintry with an increasing risk of snow as the week progresses, particularly in coastal areas or over higher ground.
"There will be widespread frosts with temperatures falling to as low as -10°C overnight in isolated spots by the end of the week."
Whilst some the coldest temperatures could be felt over Thursday, the chances of snow increase towards the end of the week.
