The episode as NWS ALY wrote it up.
A developing wave of low pressure traveled east along a nearly stationary front during the late morning and afternoon hours of Wednesday May 16th. This triggered numerous showers and thunderstorms across eastern New York State into western New England. Some thunderstorms became locally severe. The low pressure system, and attendant cold front and thunderstorms, moved southeast of the region by Wednesday evening.
