The mid-Atlantic was within the broad warm sector of a surface cyclone on September 11, leading to unseasonably warm temperatures over the region. The warm air mass allowed instability to build during the day, with southwesterly flow also bringing increasing humidity. Wind shear and lift were limited, but a weak surface trough well ahead of the cold front helped produce scattered showers and thunderstorms. A few storms became strong to severe and produced locally damaging winds.
