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 hours, clusters of thunderstorms developed across eastern upstate New York. These thunderstorms moved into southern Vermont by the late afternoon hours and produced damaging winds, mainly to trees.
The threat for storms ended as the storms moved eastward and the cold front moved across the area and into central New England by the overnight hours.
