London:
Britain was bracing itself for another weekend full of snow disruptions on Tuesday after forecasters warned of a further wintry blast bringing fresh snowfalls.
While temperatures on Tuesday night were due to plummet to as low as -13 degrees Celsius at some places, the Siberian icy chill was far from over with the big freeze due to last well into the weekend, the Daily Mail reported.
Forecasters said the Heathrow airport could be affected by up to half an inch of snow.
A spokesman for the Met Office said, "Heathrow could see some slight flurries, if it does fall it is likely we would settle. But there is little chance that it will be enough to cause major disruption."
"It is too early to say how much snow there will be, if any, this weekend."
"There is a chance of wintry showers -- which is everything between wintry rain and snow," the spokesman said.
On Monday, a homeless died in a park as temperatures plummeted to -7 degrees in Hull city. The man, believed to be in his 50s, was discovered by a dog walker.
With the cold weather showing no signs of abating, if temperatures did dip to -13 degrees on Tuesday night, it would mean the coldest thermometre readings since December 2010.
The Met Office has warned that -13 degrees is possible between Tuesday and Thursday in East Anglia region of eastern Britain.
Met Office forecaster Helen Chivers said, "Scattered snow showers were expected to affect parts of the Lincolnshire to Sussex area overnight, with freezing fog patches elsewhere which persist all day on Tuesday in parts of central Scotland.
"There's a continuing risk of ice throughout this week in areas with lying snow, and a chance temperatures could go lower than -12.4 degree, especially on Tuesday and Wednesday nights."
The coldest peak of this winter so far came on Saturday morning when South Newington, Oxfordshire, hit -12.4 degrees.
