An arctic cold front tracked through eastern New York during the afternoon of the 30th, accompanied by a heavy snow squall. Frigid air poured in behind this front along with strong westerly winds. Wind chills the morning of the 31st fell to 15 to 35 degrees below zero. The wind chills prompted many schools to close or delay opening, and there were several reports of water main breaks due to the cold.
In addition to the frigid temperatures, a heavy band of lake effect snow developed off of Lake Ontario and impacted far northern portions of Herkimer County from the evening of the 30th through the late evening of the 31st. Snowfall amounts of 8 to 12 inches occurred in this band.
