A cold front approached the region from the west on the afternoon of July 8th. Ahead of the front, a very moist and humid air mass was in place resulting in good instability. Moderate to strong speed shear associated with a deep shortwave helped convection organize into lines and bowing line segments. Wind damage was the primary threat with these storms, along with very heavy rainfall.
