Cold snap takes hold across Britain
Temperatures have been hovering around freezing point in many areas and forecasters warn the cold spell will continue to grip Britain for the rest of the week.
There have been snow showers in the south west and along the east coast, and there is more on the way before temperatures turn milder during the weekend.
Tony Conlan, a forecaster with MeteoGroup, said that in some inland parts of Wales, the Peak District and parts of the south west, temperatures had stayed on or just below 0C all day.
"Elsewhere across a large part of the UK they were between 1C and 3C," he said.
The below average readings are expected to remain for the rest of the week.
"By Wednesday night, we may see temperatures as low overnight as -8C or -9C," he added.
"On Friday night, there will be a change when northern parts of Britain see an area of snow, with perhaps two to three hours of steady falls. It will move south eastwards, but be followed by milder air, and change to rain.
"By Sunday, it will be turning significantly milder everywhere."
The lowest temperature recorded in the early hours of Tuesday was -6.2C, in Pershore, Worcestershire.
The Department of Health has advised people to check local weather forecasts for the latest information on the conditions and stay safe when outdoors. A spokesman has said: "We are working closely with the NHS and local authorities to ensure vulnerable people stay well during cold weather and get the help they need within their communities."
