The episode as NWS ALY wrote it up.
Despite being behind a cold front, the region remained in a warm and humid air mass. This allowed the atmosphere to become quite unstable.
As a cold front approached the region during the afternoon and early evening hours, clusters of thunderstorms developed across eastern upstate New York. These thunderstorms moved into northwestern Connecticut during the late evening hours and produced damaging winds, mainly to trees and power lines.
The threat for storms ended as the storms moved eastward and the cold front moved across the area and into central New England for the overnight hours.
The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
