More snow has fallen across the north of the UK, with up to 10cm settling across mountains in Cumbria, Northumbria and parts of Scotland overnight.
Glasgow and Edinburgh in Scotland saw up to 5cm of snow, with up to 4cm settling in Teesside and County Durham in northern England. Areas further south, including Lincolnshire and Yorkshire, escaped the snowfall but were greeted with rainfall and very cold temperatures instead.
The showers hitting road surfaces below 0C will have resulted in icy conditions for drivers, a weather expert said.
But while temperatures dipped to -4C in eastern England and -7C in western Scotland, areas of Cornwall and west Wales enjoyed far warmer highs of 11C.
It comes just days after severe flooding hit Britain, from which many areas are still recovering.
Brendan Jones, a meteorologist at MeteoGroup, the weather division of the Press Association, said on Monday morning the snow was continuing in the north.
"In some areas further south the snow instead turned to rain, hitting very cold conditions causing some quite tricky conditions on the roads. But warmer air coming in from the west brought much milder temperatures in the west."
He said the weather would be changeable over the next few days.
"There could be some more showers and light snow, but the cold weather will stay. There is a risk of snow throughout the winter but it is likely Scotland will see another fall on Thursday."
The Met Office removed its severe weather warning as temperatures steadily rose and the risk of cold and ice fell.
On Sunday rail passengers faced delays due to signal failures in the extreme weather.
