A weak cold front dissipated west of the mid-Atlantic on June 4. However, a lingering surface trough slowly moved through the region. With a lingering warm and moist air mass in place, the surface trough caused convection to develop, starting early in the afternoon. Despite weak wind shear, storms steadily increased in organization, aided by favorable mesoscale interactions. Several storms would go on to pose a threat for damaging winds and hail. Storms eventually coalesced into multiple linear segments which posed a continued wind damage threat. Storms moved offshore by early to mid evening, with a drier air mass behind them.
