The Met Office says conditions will get much colder for large parts of the UK this week with sub-zero temperatures and some places seeing snow, sleet or wintry showers.
Current easterly winds have made much of the UK cold in recent days - but forecasters say it is set to get even colder as the wind direction changes and brings in icy air from the north.
Met Office meteorologist Alex Burkill said we can expect to see 'Arctic air' from Tuesday, causing temperatures to drop through the week. He said: “It’s going to turn even colder and feel even colder still with temperatures well below average for the time of year both by day and by night.”
