WHERE... In New York, Steuben, Schuyler, Chemung, Tompkins, Madison, Southern Oneida, Cortland, Chenango, Otsego, Tioga, Broome, and Delaware counties. In Pennsylvania, Bradford County.

Forecast models differ on where the snow versus sleet and freezing rain divide. Some indicate the sleet and freezing rain could go as far north as Binghamton, while the other has it stopping In Sullivan County, NY. Making matters even worse, warm Lake Ontario waters may bring Lake Effect Snow into the already powerful storm.

It'll be followed by arctic temperatures with dangerous wind chills Sunday with lows well below zero.
