Environment Canada is warning morning commuters to be careful.
Parry Sound is under a snow squall warning as a storm is blowing in from Georgian Bay, bringing a possibility of heavy blowing snow, which is likely to cut down on visibility on Highway 400. MacTier is expected to be hit heaviest by the storm. Snow squalls can also quickly change conditions from blue skies to zero visibility within minutes.
The snow squalls will break up later this morning, but a new round of squalls are expected later in the day.
The area could see up to 15 cm of snow fall by Thursday.
