Snow and ice is forecast for much of Scotland with a fresh weather warning issued for Friday.
Forecasters expect up to 8cm (3ins) of snow accumulating in low levels and warned of road closures and commuter delays particularly in the morning.
A Met Office yellow warning takes effect from 06:00 until 21:00 and covers the central belt, south Scotland and parts of Highland and Grampian.
Police Scotland has urged motorists to drive carefully.
The forecast follows heavy snowstorms and bracing winds in the north of Scotland.
A major incident was declared in Shetland when thousands were left without power, while more than 100 schools were closed in Aberdeenshire, Moray and the Highlands.
While the north east will see some respite on Friday, a further warning for Orkney and Shetland will take effect from 00:00 until 10:00.

Forecasters said snow would turn to rain at low levels later in the day.
There is a chance that bus and train services may be delayed or cancelled, with some road closures and longer journey times.
While delays are likely, the Met Office added there was a smaller chance of stranded vehicles and passengers in some areas, particularly over high ground during the morning.
BBC weather forecasters said temperatures could fall to minus 10C overnight if not lower with between 5-8cm of snow falling in low levels and 10-20cm on high ground.
Meanwhile, Orkney and Shetland will see up to 5cm of snow accumulating in places.
Scottish and Southern Electricity Networks (SSEN) said its engineers had to rebuild the “critical backbone” of the network to allow more homes to be connected.
But the energy firm has warned that some of them may be without power over the weekend.
Many roads on the island have also been badly affected by snow drifts.
