The Met Office has today issued an alert for snow and ice alert in Tayside.
Parts of Perthshire and Angus are included in the at-risk area.
The warning will come into affect at 3am on Friday and is in place until 9am on Saturday.
A statement on their website says: “A band of rain will turn to snow over the highest level routes in Highland and Grampian overnight Thursday night into Friday morning, then gradually down to some lower levels through Friday afternoon and evening.
“This band will slowly ease in the early hours of Saturday morning, but with colder air arriving from the east, ice will form on many surfaces.
“Some roads and railways will be affected with longer journey times. There is a small chance of stranded vehicles and passengers.
“There is a small chance that power cuts will occur, and other services, such as mobile phone, may be affected.
The chief forecaster added: “Around 5-10 cm of snow may accumulate on high ground above 200m with 20cm possible over hill routes with some drifting in strong south-easterly winds.”
