Lake effect snow will linger through the morning southeast of Lake Ontario before dissipating by the early afternoon.
Light snow will be possible at times starting this evening and continuing through Saturday. Light snow this evening will occur as a warm front crosses the area. Light snow will be possible on Saturday as a pair of cold fronts track across the area through the day. Most areas can expect only a coating to an inch of snow, but areas of higher terrain across the western Southern Tier and east of Lake Ontario will have the potential for up to 4 inches of snow.
Another round of Arctic air will move into the region starting Sunday and continue for most of next week. There will also be the potential for significant lake effect snow starting Sunday night as well.
