A weather warning has been issued for snow and ice for the entire north and north-east.
The Met Office has forecasted snow could lead to icy surfaces in Aberdeen, Aberdeenshire, Moray, Highlands and the islands.
The warning comes into effect as of 3pm this afternoon and will last until 11.59pm tomorrow.
On Friday, people can expect heavy snow showers which could make driving conditions difficult and disrupt travel.
The yellow warning for snow has been issued from midnight on Friday until noon the same day.
A Met Office statement said: “A band of sleet and snow will arrive across northwest Scotland on Wednesday afternoon and move southeastwards across most parts of Scotland overnight, clearing southwards on Thursday morning.”

It added: “1cm to 2 cm snow is likely to settle at low levels quite widely with 3cm to 6cm above 200m, and up to 10cm above 300m.
“Rain is more likely around some coasts, and snow may also turn to rain at low levels inland before clearing to leave a risk of ice on untreated surfaces on Thursday morning.
“Following the clearance of the rain, sleet and snow on Thursday morning, much of inland Scotland will be dry for most of the day.
“However, snow showers will then follow into northern Scotland on Thursday, especially during the afternoon and evening.”
Some roads and railways are likely to be affected, and people should expect longer journey times.
