Expect 'snow, ice and low temperatures' this week
The Met Office's chief meteorologist, Matthew Lehnert, said "snow, ice and low temperatures" were the main themes of this week's forecast, explaining the UK was under an Arctic maritime air mass.
"The focus for the snow moves to southern England and South Wales tomorrow and some may wake up to a few centimetres of snow, with the south coast and far south-west likely to see a mix of rain and sleet," he said.
"Further snow and hail showers are also expected along northern coasts, especially in northern Scotland."
He added: "During the afternoon, a further spell of sleet and snow is likely to develop across southern England and South Wales which could cause travel disruption into the evening. The impact of lying snow and ice on untreated surfaces may have an impact on Thursday morning travel."
