The episode as NWS BTV wrote it up.
An elongated storm system intensified across New England-NY on February 27th and then slowed forward progression across Quebec on February 28th. A wintry mix of snow and rain fell on the 26th and morning hours of the 27th before changing to snow/snow showers at midday. A prolonged west-southwest flow of cold, unstable air across the long fetch of Lake Ontario, developed a very pronounced and intense lake effect snow band south of the region during the afternoon of February 27th, that eventually rotated north into the region by the evening and eventually left the area by midday of February 28th.
A narrow band of 12 to 20 inches of snow fell across southeast St. Lawrence county in the vicinity of Route 3.
