Commuters have been hit by snow, ice, flood water and cold temperatures as forecasters warned there would be more to come mid-week.
Snow showers caused disruption to travel in south east England before moving westwards throughout the morning, leaving a covering on the ground.
The AA said that by midday on Monday it had attended 6,800 breakdowns across the country, with more than 60 cars stuck in snow or flood water.
Across the Midlands, about a dozen schools were closed by the wintry weather.
Temperatures in the Welsh mountains, southern Pennines and at the top of the Cotswolds were just below freezing.
High Wycombe in Buckinghamshire was the worst affected by the snow with 13cm, while levels elsewhere remained at 1-3cm.
Julian Mayes, a forecaster for MeteoGroup, the weather division of the Press Association, said: "The snow is fizzling out.
"Wiltshire and Hampshire have seen some in the last few hours as snow which had been in the south east England moved west. We will have another cold, cloudy and damp day tomorrow but hopefully no more snow.
"On Wednesday we have a band of rain coming in from the west which will have snow on its forward edge, affecting northern England, high ground in Wales and across Scotland."
The Met Office issued yellow weather warnings overnight affecting much of England, Scotland and Wales, because of the danger of ice following the snow.
