Update: Lake Effect Snow Event



Morning update...

Clipper quickly making its way to east... with light snow falling in it's wake across southern NY and most of Pennsylvania this morning, some of which is locally heavy at times. Behind the departing system, expecting the lake effect machine to begin cranking by this evening and continuing into the Friday Night. Heaviest amounts will be found across the Chautauqua Ridge of western NY and into northwest PA, where upwards of a foot are expected by Friday Evening. Travel along the NYS Thruway between Buffalo and Erie will be a slow go tonight and Friday, with similar conditions expected across I-79, I-80, and I-86. To the south, the Laurel Highlands will also recieve significant accumulations thru Friday, where up to a foot is possible in locally heavier bands.

Areas downwind of Lake Ontario across xtreme eastern Wayne/Cayuga, northern Cortland/Chenango, southwestern Oswego/Oneida, Onondaga, and Madison Cntys will be hit hardest where up to a foot is expected by late Friday Evening in the most persistent bands. Travel in and around the Syracuse Metro will be highly impacted. Across Tompkinswill see Expect to see some lake enhancement from the Finger Lakes, especially Cayuga and Seneca. This will likely result in advisory level snowfall across Tompkins and southern Cortland Cntys, with lower accumulations across Schuyler, Chemung, Tioga, and Broome cntys. Further east into Otsego cnty, cannot be ruled out that extreme northwestern part of cnty cud get clipped from the main band for atleast a period of several hours...will need to watch where primary band sets up if higher accumulations may be reached.
