The episode as NWS PBZ wrote it up.
An F1 tornado touched down 5 miles northwest of Carnegie in Allegheny County and moved east-southeast across the southern and eastern suburbs of Pittsburgh into Westmoreland County. The total path length of this tornado was estimated to be 32 miles, and damage was reported in Mount Washington, Hazelwood, and Rankin in Allegheny County. As the tornado passed over a concrete railroad overpass about 2 miles north of Baldwin, it blew several railroad cars onto their sides. The tornado continued into Westmoreland county, moving through the towns of Irwin and Manor. The Mount Washington area, located just south of downtown Pittsburgh, sustained the majority of damage, along with all of the minor injuries. Property damage in the Mount Washington area included roofs blown off buildings, brick walls torn down, and other major structural damage. Over 1000 structures, mostly in the immediate Pittsburgh area, reported some sort of damage. Other than the damage on Mount Wahington, most of the damage was minor, produced as the result of tree damage from falling trees or tree limbs.
The Pittsburgh radar (KPBZ), 9 km away, was scanning. The volume nearest the first event began at 21:57 UTC.
