The episode as NWS BTV wrote it up.
Scattered thunderstorms developed in a moderately unstable airmass across the Champlain Valley of New York during the afternoon of the 16th. One thunderstorm developed in a favorable, highly sheared wind environment which eventually intensified into a supercell thunderstorm across Clinton county, NY. This supercell thunderstorm moved across the New York locations of Jericho, Keesville, northern Plattsburgh and Cumberlandhead, before heading into Lake Champlain and eventually Vermont. Significant straight-line wind damage (estimated between 60 and 80 mph) in the form of snapped, uprooted and downed trees, downed power lines and structural damage such as trees on houses as well as roof shingles and siding blown off. Also, several boats and docks were damaged in local marina. Large hail was also reported.
