Areas in central to northern Jefferson County have already accumulated several inches of snow today due to a lake response from southwest winds. The entire county remains under a Lake Effect Snow Warning through late tonight, with snow totals accumulating in the 6-10” range. Overnight, the band of snow will weaken and shift northward, creating quieter times for the North Country.
Elsewhere across CNY, a rather weak disturbance is causing a general area of flurries or light nuisance snow across through the remainder of the evening. Accumulations will be on the light side. We’re expecting snow activity to taper through the overnight, and we’re calm to start Sunday morning with some peeks of sunshine.
A couple systems will come together at the end of the weekend to spin up a bigger storm system off the New England coast Sunday evening. While this bigger storm will be too far east to directly impact us, one of the weaker systems forming that storm will move through central New York during the afternoon. This will cause snow to break out during the last half of the day. There could even be a brief period of squally weather.
As the aforementioned storm forms off New England, northwesterly winds will start to strengthen over Sunday night into Monday. That means a renewed threat for lake effect snow in central New York.
