The Met Office is predicting much of the UK to be hit with ice and snow as temperatures are set to fall even further.
It comes as a wave of Arctic air has moved in from Scandinavia from the north, blanketing the whole of the country.
This airflow is causing temperatures to plunge, but is also predicted to bring snow to much of Scotland.
However, the latest forecasts show the north east and a small part of the eastern coast of England are also set to be hit.

Fort William, Wick, Portree, and Inverness covered with snow as the weather conditions turn chaotic during the week.
Maps also show that the temperature could drop to as low as -10C on Wednesday and Thursday.
Yellow weather warnings for snow and ice cover the north of England, Northern Ireland and Wales as well as Scotland.
A spokesperson from the Met Office said: "The UK is now in the grip of a cold plunge of Arctic air which has moved in from the north across the whole of the country.
"The northerly airflow is also bringing very cold conditions for all, with snow showers for some areas at times.
"A number of National Severe Weather Warnings have been issued for potentially disruptive snow and ice over the coming days."

It comes as some weather analysts have suggested that the nation might encounter its most severe snowstorm in 14 years.
However, the Met Office is more cautious in its forecasts but added that there is still uncertainty arising from various weather systems.
Met Office chief meteorologist Andy Page, said: "Where and how much snow we will get will vary throughout the week and weather warnings could change quickly, you will need to keep an eye on the forecast for your region for the latest information.
"There will be widespread frost this week and we could see some fairly deep laying snow in parts of northern UK and strong winds could result in drifting or blizzard conditions at times.
"The snow and ice will be disruptive and could potentially impact travel plans, make driving dangerous and pavements slippery."
