30-50cm of Lake Effect Snow

A contrail from an airplane lines the sky in Kemptville this morning, as the sun rises through high clouds generated by the Alberta Clipper.

A Lake Effect Snow Warning is in effect for the counties around the Great Lakes from NY to Michigan and in Ontario from Windsor through London towards Barrie. An Alberta Clipper dropped 5-10cm of snow last night in southwest Ontario and has raced south into the US. On the backside of this system strong northerly winds will flow across the open waters of Lake Huron, Ontario and Erie and generate very impressive bands of heavy lake effect snow. Over 30cm is a real possibility in Ontario and New York with some locations approaching 50cm. Travel in southwest Ontario along the 400 series of highways and north from Toronto towards Barrie and points west to Georgian Bay may become very difficult if not impossible over the next 24 hours.
