YORKSHIRE was put on snow alert this morning as people returned to work following the New Year break.
Areas of Scotland and Northern Ireland saw a dusting of snow overnight, with parts of northern England braced for a covering too.
The Met Office has issued heavy snow warnings for Strathclyde and south-west Scotland, Lothian and Borders, north-west England and the Yorkshire and Humber region - especially over higher ground.
Forecasters said there would be further outbreaks of snow across northern areas later today, with rain sweeping across much of the rest of England.
People hoping to catch a glimpse of a solar eclipse were also likely to be left disappointed by the predicted cloudy conditions.
Temperatures hovered around zero for many places inland overnight, but will rise to low single figures during the day. It will also be warmer in the west.
Aisling Creevey, of MeteoGroup, the Press Association's weather division, said although temperatures would rise, the outlook for the first week of the year was unsettled with more wind and rain to come.
She said: "There is a cold front catching up on a warm front. There will be some snow over higher ground and quite a bit of rain and sleet.
"We are expecting 5-8cm across parts of Dumfries and Galloway and South Lanarkshire, turning increasingly into rain as the night progresses.
"The front will move south and east overnight reaching parts of England including Wales, the South Midlands and East Anglia where it will be cloudy with a few spots of rain and drizzle.
"There will be clear spells tonight over North Wales, Lincolnshire, Lancashire and Merseyside."
She added: "The outlook for the week is less cold than the conditions throughout much of December, but it will be unsettled and breezy. Pretty much everywhere will see rain in the coming days."
