The low pressure system responsible for the heavy rain moved northeast from Atlanta, Georgia the morning of the 21st to Albany, New York the morning of the 22nd. Enough cold air came in around the low to change the precipitation to snow before it ended across western New Jersey. Accumulations were limited to the higher terrain in northwest New Jersey and averaged two inches or less in Hunterdon, Warren, Morris and Sussex Counties.
