Event narrative

Severe thunderstorm outflow winds gusted up to 51 mph at Buoy 44007.

Wider weather episode

A strong mid-level trough ejected out of New York and pushed from southwest to northeast across New England during the day on September 8th. This feature had ample low level instability to work with as the region was experiencing well above normal temperatures and moisture for early September. All these ingredients came together to bring a line of strong thunderstorms that moved from the south to the north from the NH/MA border up to Casco Bay.
