The Met Office has updated its snow warning to cover more of the north-east.
The alert covers southern and western parts of Aberdeenshire, the central belt and northern England.
The warning is in place from 4am until 9pm on Saturday.
Towns in the north-east likely to be impacted include Inverurie, Braemar, Aboyne, Huntly, Keith and Brechin.
A statement on the forecaster’s website said: “There is a small chance of significant travel delays on roads with some stranded vehicles and passengers, along with delayed or cancelled rail and air travel.”
“A developing area of low pressure is expected to track across Northern Ireland, northern England and southern Scotland on Saturday.
“As this runs into colder air, snow is likely to develop, particularly in any heavier bursts of precipitation.
“The largest snowfall amounts will be confined to higher ground, with the potential for 10-20cm of snow above 350m.
“Between 100m and 350m elevation, a mixture of rain, sleet and snow is more likely, but there is potential for accumulations of 2-5cm, and a small chance of 10cm should the precipitation be heavy enough to maintain snow for a longer duration.
“With warm air close by to the south, it may be that places in the south of this warning area end up with mainly rain.”
The forecaster explained the reason for the update, adding: “The warning area has been pulled northwards, out of parts of northern England but also pulled towards the Great Glen. Northern Ireland will have a separate combined rain/snow warning.”
