A persistent northwest flow of cold air across the relatively warm waters of Lake Ontario led to a long duration, major lake effect snowstorm across a large part of central New York and far northeast Pennsylvania. The snows began on Saturday the 4th and became heavy at times downwind of Lake Ontario from the 6th to the 8th, then tapered down by the 9th. Hardest hit was the Syracuse area where up to 58 inches of snow fell on the east side of the City. Most of the Syracuse area received between 38 and 55 inches of snow with the official snowfall at Syracuse International Airport between the 4th and 9th measured at 46.1 inches. This is the 4th highest four day snowfall on record at the Syracuse airport. Other locations in central New York downwind from Lake Ontario picked up between 1 and 2 feet of snow. At the Binghamton Regional Airport, 21.7 inches of snow fell, which was the biggest lake effect snowstorm on record.
