Severe weather warnings for almost all of the UK are in place, with heavy snow, widespread icy roads and bitter temperatures forecast.
Some 10ins (25cm) of snow is expected to fall over higher ground, while parts of the Midlands and London will not escape a dusting. Overnight temperatures across the UK plunged well below zero again, after a day when much of the country was badly disrupted by the earliest widespread snow for 17 years.
The Met Office said London and the South East, the South West, East Midlands, Yorkshire and Humber and the north east of England face widespread icy roads. The North East, Yorkshire and Humber, East Midlands and the South West were also braced for heavy snow and Wales and Northern Ireland can expect icy roads while Scotland is in line for more heavy snow and drifts thanks to a biting wind.
Forecasters said the cold snap is set to tighten its grip, blanketing swathes of the country in white by the middle of next week.
Aisling Creevey, of MeteoGroup, the weather division of the Press Association, said: "It's definitely staying cold and going into next week, we could see a lot more snow. There is a low pressure system across the country and if it moves the way it is looking to at the moment, it's going to be very windy, very snowy and really bitter."
Temperatures will barely rise above freezing on Saturday, with the South West set to be the warmest at around 3C.
