As a strong ridge that provided heat and humidity to the area slowly pushed off to the southeast, a cold front approaching from the Ohio Valley and Great Lakes dropped to near the Mason/Dixon line by the morning of the 30th.  A weak shortwave trough provided only a minor push to the boundary, tracking across northern Ohio and Pennsylvania.  Showers and thunderstorms were able to form ahead of the boundary, with several strong storms producing wind damage north of Pittsburgh.  The line had weakened when it arrived in the Pittsburgh metro area by evening.
