Just after midnight, winds across western NY are swinging around into the southwest. This wind shift will translate eastward and eventually the band of persistent lake effect snow will shift north out of CNY. By sunrise Saturday, we should see some breaks of sun. A few snow showers are possible off of Lake Erie over the western Finger Lakes.
Outside the lake effect snow Saturday morning, a jet stream disturbance approaching from the north will causes a general area of flurries or light snow across the rest of central New York Saturday afternoon. Other than that it will be quiet and cold, with a bit of a southwest wind.
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.
