The episode as NWS BTV wrote it up.
Daytime heating across the Green Mountains of Vermont, with a moderately unstable airmass in place, resulted in the scattered thunderstorms during the afternoon of the 12th. Low pressure stalled within the Gulf of Maine, resulted in northeast to southwest movement of these storms along a boundary across the southern Green Mountains. Flash flood producing rainfall resulted from several thunderstorms that trained across southeast Rutland county.
Flash flooding washed out roads, and resulted in debris over roads in Wallingford as well as State Highway 103 in East Clarendon and Shrewsbury.
