Winds have shifted out of the southwest, lifting the remainder of yesterday’s lake effect snow well to the north. This lake response will likely remain in the North Country through the day, providing snow showers close to Watertown and the St. Lawrence River. Jefferson County is under a Lake Effect Snow Warning through tonight. By 7pm, areas under the most persistent snow may see 6-10” of new accumulation. Elsewhere in central New York, expect the first half of the day to feature clouds with breaks of sun. A few flurries are possible.
A jet stream disturbance approaching from the north will causes a general area of flurries or light nuisance snow across the rest of central New York this afternoon. Accumulations will be on the light side. No more than 2” is expected at most. 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.
