Britain has been issued with a yellow warning for snow and strong gusts of bitterly cold wind arriving from Greenland and Iceland.
Showers across parts of Scotland and Northern Ireland that occurred on 28 January are predicted to extend to parts of northern England and Wales on Thursday afternoon.
The Met Office has called for the public to be aware of possible disruption to travel, while health officials urged people to take extra care outside.
Where will it snow?
Several inches of snow are predicted in the Midlands, northern parts of England and Scotland. More than 15cm is possible over higher ground.
How cold is it going to get?
Temperatures predicted to drop by 10C overnight on Thursday 29 January. The whole of Britain will feel below freezing as Arctic winds make plummeting temperatures feel even colder, although the south will escape the worst of the grim weather.
During the afternoon in London temperatures will drop to around -3C and fall to -4C across northern Britain, while the temperature over the Pennines and Scottish Highlands will go as low as -10C.

Should I be concerned about travel disruption?
Strong, gusty winds will lead to drifting and temporary blizzard conditions over high ground, while icy surfaces could pose additional risks in some areas.
The Met office has warned that the public should be aware of the potential for disruption to travel and hazardous driving conditions. Further snow showers will affect parts of Scotland and Northern Ireland over the weekend, with strong winds that are likely to cause drifting and temporary blizzards.
How long will the cold snap last for?
Temperatures are expected to lift back to 10C by Thursday 5 February, with snow showers becoming less frequent.Reuse content
