What happened
The episode as NWS ALY wrote it up.
An unusually very cold air mass for mid-November moved into upstate New York from Canada. With a constant flow of cold air over the relatively-warm waters of Lake Ontario, a strong band of lake effect snow developed on Tuesday, November 18th.
Initially, this band occurred over areas just north of the Western Adirondacks during most of the day on Tuesday, November 18th. By the late evening hours, the band shifted south and affected far northern Herkimer and Hamilton Counties. This snowfall, falling at rates easily in excess of one inch per hour, continued over the same locations of the western Adirondacks for several hours in a row through the overnight hours. Up to 13 inches of snow fell across far northern Herkimer and northwestern Hamilton Counties before the band weakened and shifted north of the area on the morning of Wednesday, November 19th.
