Broad ridging was in place across the Mississippi Valley on the morning of the 7th, with the Upper Ohio Valley region experiencing WNW flow aloft.  After morning showers and thunderstorms moved across the area due to a warm front, the upper level flow regime brought an elevated mixed layer (EML) into the region during the afternoon, capping convection during the afternoon and early evening hours.
Convective clusters over Michigan during the evening congealed into a mesoscale convective system (MCS) and raced across Lake Erie, arriving in the NWS Pittsburgh forecast area shortly before midnight.  Steep mid-level lapse rates thanks to the EML allow for a few large hail reports initially.  However, the main impact of the system would be from wind.  Surface temperatures surged into the low to mid 60s ahead of the line on gusty southwest winds, resulting in surface CAPE of 1000 J/kg and a significant curving/lengthening of the hodograph. With the boundary layer no longer decoupled, strong ambient mid-level flow combined with highly efficient evaporational cooling in the convective downdrafts allowed substantial downdraft CAPE to be realized with surface wind gusts exceeding 70 mph observed and evident over a wide area given the volume of wind damage reports.  Embedded vortices in the quasi-linear convective system also led to five tornadoes in the EF0/EF1 range during this event across the region.
Numerous instances of tree and structural damage were observed, including damage to planes and hangars at Arnold Palmer Regional Airport.  Strong winds also tore off part of the roof of St. Mary of Czestochowa Church on Kenneth Avenue in New Kensington. Over 50,000 area electrical customers were without power in the wake of the storms, according to the Pittsburgh Post-Gazette.

This is a continuation of the tornado path that began near Union Ridge in Columbiana County, Ohio.
A second damage swath coincident with a second radar-detected
circulation and distinct from the Rogers/Negley tornado above was
encountered west along Carmel Achor Road, beginning in the woods
north of the road. This path proceeded south-southeastward with
continuous limb damage and occasional stronger gusts leading to
uprooted trees. Structural damage encountered along this segment
of the path seems to have resulted from falling trees rather than
wind.
The track curved eastward along Pancake Clarkson Road, crossing at
into Beaver County, PA at the Pennsylvania state line, where it
appears to have intensified and widened slightly. In this
location, numerous evergreen trees were snapped or uprooted in the
Sheepskin Hollow State Nature Preserve.
The circulation weakened quickly thereafter, with occasional tree
damage continuing to near Lihi Road and Lisbon Road in Beaver
County before evidence of a path disappeared altogether.

Reported by: NWS Storm Survey

A mesovortex intensified rapidly and produced a tornado as its
parent storm descended the terrain northwest of Tarentum into the
Allegheny River valley. The tornado began in the woods between
Bakerstown Road and Days Run Road and rapidly intensified near
Days Run Road and Holsing Lane, where a vast number of softwood
and hardwood trees were snapped, blocking Days Run Road, and with
some falling onto homes. Additionally in this location, windows in
a home were blown in by the tremendous wind.
A swath of tree damage, likely to be the result of straight-line
wind, extends northwest from the Holsing Road area where it
intersects the tornado damage track. This wind likely was just as
strong (if not stronger) than the tornado itself.
The tornado slowly weakened as the storm continued southeastward,
with a path of snapped limbs and occasional trunks continuing to
along Bakerstown Road near the Broadview section before continuing
across Route 28. Modest building/carport damage was reported in
Tarentum along Sixth Ave coincident with the passage of the
weakening circulation.  The tornado then crossed the Allegheny River into Westmoreland County.
