An Alberta Clipper is expected to pass by over Lake Huron and Georgian Bay Friday then into the Ottawa Valley area or Southwestern Quebec Friday night, bringing a large area of snow with it.

Latest indications suggest a total of 10 to 20 cm of snow across much of the area Friday and Friday night. The snow may become mixed with ice pellets or freezing rain near Northern Lake Huron and Georgian Bay.

Driving conditions are expected to quickly deteriorate Friday once the snow arrives.

Environment Canada is closely monitoring this situation. Snowfall warnings may be required as this event draws closer.
