Following a cold front that brought four to six inches of snow to the eastern Lake Ontario region, a broad west to east flow followed over Lake Ontario early on the 30th. A convergence boundary combined with little wind shear aloft, ample moisture in the boundary layer and cold air to provide ideal lake effect conditions.

The episode as NWS BUF wrote it up.
Following a cold front that brought four to six inches of snow to the eastern Lake Ontario region, a broad west to east flow followed over Lake Ontario early on the 30th. A convergence boundary combined with little wind shear aloft, ample moisture in the boundary layer and cold air to provide ideal lake effect conditions. These ingredients combined allowed for a steady band of heavy lake effect snow southeast of Lake Ontario. Prior to sunrise on the 30th several inches of snow had fallen across far northwestern Wayne, northern Cayuga and western Oswego county. As the intensity of the snow band increased through the morning hours, the band of snow remained over western Oswego county with snowfall rates between three and four inches per hour over a several hour period. The focus point for this lake effect snow was on the city of Fulton and vicinity where nearly three feet of snow fell. Snowplows at one point within the city had to stop plowing as visibilities within the heavy snow became dangerously low for driving snowplows. Winds gradually backed to westerly through the day, and by time the band of snow shifted northward it was rapidly weakening, making this event localized to primarily western Oswego county and vicinity.
