Parts of Tayside will be hit by “heavy wintry showers” until Friday, say forecasters.
A Met Office yellow warning for snow and ice which is in place for the region – and neighbouring Fife – has been extended and is now effective from 9.35am on Thursday until 10am on Friday.
It comes after roads were closed in Perthshire as a result of heavy snowfall on Wednesday.
The Met Office said the highest routes within the warning area – which includes the Highlands, Western Isles and Strathclyde – could experience as much as 7.9in of snow overnight into Friday, with “temporary blizzard conditions” possible in places.
The worst of the wintry weather is not predicted to make it as far east as Dundee, Perth and much of Fife and Angus. However lower levels are expected to endure a mixture of rain, sleet, hail and ice.
The A93 Braemar to Perth road at the Spittal of Glenshee remains closed this morning, however gritters are working to reopen the route.
A Met Office statement said: “Heavy wintry showers will lead to some lying snow, particularly over high ground, through Thursday and overnight into Friday morning. Ice is also expected to form widely overnight into Friday.
“Some roads and railways likely to be affected with longer journey times by road, bus and train services as well as some injuries from slips and falls on icy surfaces.
“With strong winds drifting snow is also possible with temporary blizzard conditions possible in showers. Conditions are expected to improve overnight into Friday with showers becoming less frequent but then ice will become the main hazard.
“This is an update to extend the warning into Friday morning and increase the likelihood of impacts being seen.”
The Met Office’s chief forecaster said: “Frequent showers will push across northwest Scotland falling as snow, mainly above 200m (356ft).
“Snow could build up to give 10-20 cm (3.9in-7.9in) over the highest routes in parts of northern Argyll, Lochaber, Wester Ross and Easter Ross through Thursday and overnight into Friday with strong winds leading to some drifting and also temporary blizzard conditions.
“At lower levels showers are more likely to fall as a mixture of rain, sleet and hail potentially washing off any treatment with surfaces turning icy, particularly overnight into Friday.”Â
