Britain is at the ready for an invasion of freezing temperatures and even snow in some regions.
The mercury is forecast to plunge in all areas of Britain this weekend, with Scotland and the east coast being hardest hit.
The start of 2013 has seen mild temperatures-on Thursday Cornwall recorded 9C-but they are forecast to fall dramatically.
Alexi Boothman, a forecaster with MeteoGroup, the weather division of the Press Association, said: "Temperatures will fall over the weekend, and in many places, even during the daytime, we won't see more than a degree or two above zero.
"From overnight tonight we can expect to see wintry showers arriving in parts of Scotland and north-east England, driven by cold easterly winds, and also down the east coast as far as East Anglia. There may also be some snow showers in Wales."
The Highways Agency described its state of readiness as "well prepared" ahead of the cold snap.
A spokeswoman said: "We have a fleet of 500 state-of-the-art winter vehicles on stand-by, supported by tried and tested winter resilience plans.. We have reviewed salt stock levels and taken action where needed to enhance our resilience."
