From February 10 to 11, a low pressure system developed near the Rockies and moved towards the Great Plains of the United States. It later tracked across the Ohio Valley and merged with a new coastal low. It then moved over eastern Quebec on February 14 before exiting northeastern Quebec and Newfoundland and Labrador on February 16. It dumped over six inches (15 cm) of snow across numerous areas from Iowa to New Brunswick, including major cities such as Akron, Detroit, Champaign–Urbana, Chicago, Cleveland, Columbus, Springfield, Peoria, Indianapolis, Fort Wayne, Dayton, Toledo, Cincinnati, London, Hamilton, the Niagara Region, Toronto, Sherbrooke, Saguenay, Trois-Rivières, Ottawa, Montreal, Quebec City, Pittsburgh, Buffalo, Rochester, Windsor, Syracuse and Albany. This also includes areas such as Northern Oswego County, New York, which received historic lake effect snowfall amounts in the week prior to the storm.
