The episode as NWS ALY wrote it up.
On August 20, low pressure traveled across eastern New York prior to daybreak. A line of thunderstorms formed in association with a cool front tied to this low. Training thunderstorms brought heavy rainfall to the northern Catskills and eastern Mohawk Valley. Two to 3 inches of rainfall fell in a couple of hours in a narrow band across Schenectady. Pools of water formed in some poorly drained locations, and one incident of a water rescue within the city was reported by law enforcement personnel.
