Lake Effect Snow Squalls

Downwind of Lake Huron, Ontario - Jan. 02/03 2012

A dome of cold, arctic air brings wind chills of -25C and heavy lake effect snow.

Whenever very cold air passes over the relatively warm waters of the Great Lakes, a phenomenon known as lake effect snow squalls can occur. These narrow bands of intense snow are very localized, but can drop massive amounts of snow. In addition, these cold winds cause frigid wind chills and poor visibility due to blowing, drifting snow conditions. Mark Robinson and I were out in these conditions for 2 days, filming material for a winter weather episode of the series "Stormhunters" for The Weather Network.
