A very hot and humid air mass remained in place over the mid-Atlantic on June 9, following several days of unusually hot and humid conditions for the season. Similar to the previous day, afternoon thunderstorm development occurred in the mid-Atlantic mainly due to the influence of a weak cold front to the north and a weak surface trough. Like the previous day, storms were disorganized due to weak wind fields and a lack of forcing. However, the strong to extreme instability allowed some storms to briefly become severe with a threat for damaging winds, hail, and torrential rain. Convection gradually dissipated during the evening hours with the loss of daytime heating.
