A near record warm air mass was in place over the mid-Atlantic on June 30. Combined with fairly high humidity, moderate to strong instability built over the region. An approaching surface trough acted to trigger scattered thunderstorms over the area during the afternoon and evening hours. Shear was not very strong, which limited overall storm organization. However, some storms did become strong to severe and produced instances of damaging winds. Convective activity diminished during the later evening hours with the loss of daytime heating.
