Weather Trivia: Lake effect snow is a common winter phenomenon around the Great Lakes, caused when cold air moves over the relatively warmer waters of the lakes, picking up moisture and heat. This leads to the formation of snow squalls on the leeward shores, a key feature of winter weather patterns in areas like Sault Ste. Marie.
