Hail and Damaging Wind in Vermont, June 12, 2007
Daytime heating across the Green Mountains of Vermont, in a moderately unstable airmass caused the development of scattered showers and thunderstorms during the afternoon of the 12th. These storms moved in an uncharacteristic northeast to southwest direction due to a large scale circulation caused by a stalled coastal low in the Gulf of Maine.

What happened
The episode as NWS BTV wrote it up.
Daytime heating across the Green Mountains of Vermont, in a moderately unstable airmass caused the development of scattered showers and thunderstorms during the afternoon of the 12th. These storms moved in an uncharacteristic northeast to southwest direction due to a large scale circulation caused by a stalled coastal low in the Gulf of Maine. One storm briefly strengthened in Addison county and produced one inch diameter hail in Shoreham and knocked down trees and powerlines in Bridport.
