A very humid airmass with dewpoints well into the lower 70s was in place over the Lower Ohio Valley during the late morning and early afternoon on July 10th.  A sharpening trough over the western Great Lakes brought moderate mid-level northwest flow over the region during the afternoon hours.  Strong instability and the absence of a cap allowed individual strong storms to develop by early afternoon across northern Kentucky along Interstate 64.  Some of these storms brought localized damaging wind gusts.  A cold pool driven short bowing segment crossed Harrison and Floyd counties in Indiana during the mid afternoon hours, eventually crossing the Ohio River and entering Louisville. This bowing segment brought widespread damaging winds to Louisville, including a 64 mph measured wind gust at Standiford Field in Louisville.
