The episode as NWS ALY wrote it up.
A storm system moved from the Great Lakes and into the Northeastern United States. The storm's warm front was draped across the region. As skies cleared out in the late morning hours, the atmosphere became increasingly unstable. Warm and moist air set the stage for the potential for strong to severe thunderstorms. With lots of wind shear present, there was the potential for damaging wind gusts and even tornadoes as well.
A strong squall line develop across western New York and western Pennsylvania and moved eastward, producing significant damage along its path. As the line of storms reached eastern New York, it clipped portions of Ulster and Dutchess counties, producing widespread wind damage during the evening hours. Media reported that 8,400 customers lost power in Dutchess County alone. The line quickly advanced eastward into New England, ending the threat for severe weather.
