What happened

The episode as NWS BTV wrote it up.

A very warm, humid and unstable airmass was located across Vermont during the afternoon of the 25th, with temperatures in the upper 80s to lower 90s and dewpoints around 70 degrees. A surface cold front was located across Ontario and Quebec, with a mid-atmospheric disturbance that moved across the North Country during the afternoon and early evening. This triggered numerous thunderstorms in New York, that intensified as they moved across Vermont. An unseasonably strong wind field aloft fueled the development of severe thunderstorms that produced widespread damaging winds and some large hail across central, southern and eastern Vermont. Some of the hardest hit communities included Barre (Washington county), Rutland and vicinity (Rutland county) and Woodstock (Windsor county).
