Temperatures fell as low as -14C (6.8F) overnight as waves of Arctic air continue to move across the UK.
Tuesday evening was the coldest January night since 2019, the Met Office said.
Bitter conditions and significant snowfall forced schools to shut in Scotland and northern England on Tuesday amid yellow warnings for ice and snow across all four UK nations.
Forecasters say Wednesday night could see the coldest January temperature for 14 years.
By the end of Friday, more than 40cm of snow may be seen on high ground in north-west Scotland, as wintry weather continues, the Met Office said.
Snow, sleet and rain are expected to continue blanketing northern parts of the UK, though there will be some sunshine.
Heavy frosts and freezing conditions are likely across virtually the entire country, with experts warning of treacherous pavements and roads.
The low of -14C was seen in provisional recording by the Met Office in Dalwhinnie in the Scottish Highlands.
The forecaster said on Tuesday that overnight temperatures in snow-covered parts of Scotland could fall as low as -15C, which would make it the coldest January night since 2010.
"It is still one of the coldest January nights in the last five years," Met Office forecaster Liam Eslick said.
