This weekend's big freeze could fetch temperatures as low as -16C, the Meto Office has warned.
Snow is expected to continue to cause widespread travel disruption across the UK.
Scotland could see lows of minus 16C (3.2F) tonight lasting into Sunday, as the cold snap continues.
A low of minus 15.4C (4.3F) was recorded just before midnight on Thursday at Braemar in the Scottish Highlands, while Shap in Cumbria dipped to munis 8.3C overnight.
Meteorologist Alex Burkill said parts of England could also see sub-zero temperatures reach double digits.
He said: "Over Saturday we'll see some snow showers around the far north, the far west and the far east of the UK.
"Elsewhere it's a cold day again and feeling especially cold in the south where it will be breezy, but for most it will be dry and sunny."
He continued: "Tomorrow night it's likely to be very similar to Thursday night – we could get down to minus 16C (3.2F) in Scotland, but it's worth bearing in mind that even across the south we could get into negative double figures."
He said Benson in Oxfordshire was one of the spots predicted to reach minus 10C (14F) or below.
"Across the bulk of the UK, tomorrow night's going to be really cold."
Although Cornwall and parts of the South East that were heavily hit over Thursday night and Friday are not expected to see any more showers, drivers were warned to beware of ice roads caused by lingering snow.
Sleet and snow did continue into the early hours of Saturday morning across Kent, hampering efforts to free motorists stranded on the A229 and A249.

Kent Police said it seen an "incredibly busy night" with multiple vehicles stuck.
The force also said there had also been "numerous RTCs (road traffic collisions) and vehicles going the wrong way on the motorway".
