The north east and Scotland will see scattered snow storms throughout the day add a further 5cm of the white stuff on higher ground and up to 2cm on lower ground.
Coastal areas across England, Wales and Scotland will feel the worst of bitterly cold winds of up to 50mph, which will force temperatures down by around eight degrees.
Matt Dobson, a forecaster for MeteoGroup, said: “The worst of the snow storms will hit the north-east of England from Northumberland down to Norfolk, and will be heavier over higher ground in places like the North Yorkshire Moors and Lincolnshire Wolds.
“While temperatures will be around two to five degrees in the north and around four to seven degrees in the south, they will actually feel up to eight degrees colder because of the winds.
“Everyone should take into account when they’re checking their phones for temperatures - it’s worth taking an extra layer today.”
Despite the continued cold snap and snow, he added that disruption is likely to only affect higher ground, including mountain roads and walking routes.
More light snow is expected in northern England and Scotland again on Thursday, with the risk of some falling across southern areas on Friday.
On Tuesday, Manchester Airport was forced to suspend runway operations for a period to clear snow. It cancelled two flights, while another was diverted to Liverpool, as flurries made their way south.
The latest cold snap comes less than a fortnight after blizzards brought days of disruption to schools, airports and traffic networks.
