A deep and strong low pressure system traveled across the central United States into the lower Great Lakes on December 12th. Meanwhile, low pressure developed along the frontal boundary of the Great Lakes storm in the mid-Atlantic states and strengthened as it moved north across New York and western New England late on the 12th and 13th.
Rain that had fallen on December 12th changed to snow around midday on the 13th as the cold front swept across northern New York accounting for rapidly falling temperatures and a quick freeze. Numerous vehicle accidents occurred due to wet roads that quickly became snow covered and icy. Snowfall accumulations across northern New York were generally 3 to 6 inches with localized higher amounts in the mountains. Some specific snowfall amounts include; 6 inches in Lake Placid (Essex county) and Malone (Franklin county), 5 inches in Norfolk (St. Lawrence county) and Plattsburgh (Clinton county) with 4 inches in Moriah (Essex county).
