A yellow weather warning has been issued across the north-east and the Highlands.
Wintry showers are expected from 9pm tonight until 11am on Christmas Eve across Moray, Aberdeen, Angus and Aberdeenshire.
The Met Office is warning icy patches and snow could create some difficult driving conditions with journey times likely to take longer than normal.
It is also thought public transport routes will be affected.
A Met Office statement added: “Showers across northern Scotland will turn more persistent from late evening, with snow occasionally falling to low levels through the night.
“This will result in widespread icy patches on untreated surfaces, and up to 1cm of snow below 100m away from the coasts, with 2 to 3cm between 200 and 300m.
“Showers will turn less frequent after dawn on Christmas Eve.”
Residents have been warned to look out for icy patches on some untreated roads, pavements and cycle paths.
Aberdeen is expected to see some snow fall overnight from around 2am with a maximum temperature of 1, minimum -3.
