...NWS Damage Survey for 06/26/24 Tornadoes in Allegheny,
Washington, Westmoreland, Indiana, and Greene counties - Update #3...

.Update...
This will serve as the final, combined PNS for the five confirmed
tornadoes in Southwest Pennsylvania on Wednesday evening.

Additional information will be forthcoming for damage in the
Wilmerding, PA area to north of Trafford, PA in Allegheny County
as this area is surveyed. Aerial footage and reports from
residents and utility crews indicate a narrow swath of intense
damage in the neighborhood just south of Overlook Park in the
Wilmerding area. Damage may extend farther to the east-southeast.
This stretch of damage will be evaluated as a potential sixth
tornado track.

.Overview...
On the evening of Wednesday, June 26th, just before 730 PM EDT,
a small, but intense squall line rapidly developed along the
Washington and Allegheny county line just southwest of Imperial.
This storm progressed rapidly eastward over the next hour,
traveling nearly 50 mph just south of US 22, all the way to the
Laurel Highlands. In addition to widespread straight-line wind
damage, this storm ultimately spawned 4 tornadoes, including two
that were at one point on the ground simultaneously south of
Delmont in Westmoreland county. A 5th tornado was documented with
a separate storm over Greene county. These storms were well
sampled by both the NWS Doppler Radar in Moon Township, as well as
the Pittsburgh International Airport Terminal Doppler Radar
located near Frankfort Springs in Beaver County.

Survey Summary:
A National Weather Service survey team concluded that a tornado began
near the intersection of Old Steubenville Pike Rd and Route 22 on
the Washington and Allegheny County border, and then progressed
east-southeastward toward the town of Oakdale. Damage was sporadic
and primarily to trees, with several trees sheared off near the
top, and a few large trees snapped lower on the trunks. More
concentrated damage was noted on Seabright Rd, Kelso Rd, and
Whittengale Rd. In these areas, several large hardwood and
softwood trees were snapped midway up their bases. Two large trees
were also uprooted on Whittengale road. These locations are what
prompted the EF1 designation, as little damage was noted to
structures, except from where trees had fallen near or on them.
The tornado then weakened as it progressed toward Oakdale. Some
damage was noted to a few trees in Oakdale with large branches
broken.

End Lat/Lon:            40.3557 / -79.6202

Survey Summary:
Ground and aerial surveys confirmed tornado damage began in the
high terrain south of Turtle Creek, in the Wilmerding and East
McKeesport area, continuing across Trafford, through hilly, rural
terrain and ultimately crossing the Pennsylvania Turnpike before
finally dissipating just east of the Bushy Run Battlefield
parkland near Harrison City. Damage with this tornado was
primarily confined to trees, of which untold thousands were
damaged, uprooted, or snapped along the tornado`s path.
Considerable tree damage was observed throughout Trafford, along
with minor roof damage, and utility pole separation leading to
widespread power outages. Both dugouts at the baseball field
adjacent to Trafford Elementary/Middle school were also destroyed.
Other areas of concentrated tree damage were noted in the dense
woodlands near Pine Hollow road, neighborhoods around Government
Road just west of the Pennsylvania Turnpike, as well as in the
Bushy Run Battlefield park area near Harrison City. Areas of
straight-line wind damage, similar in intensity to the tornado,were
sporadically observed both north and south of the tornado,
particularly in the area just southeast of Bushy Run Battlefield
Park.

Special thanks to the employees and volunteers at Bushy Run
Battlefield State Park who aided survey efforts.

and New Alexandria...

End Lat/Lon:            40.3768 / -79.456

Survey Summary:
The second tornado to impact Westmoreland county began just north
of the previous tornado while it was still ongoing, with roughly
5 minutes of overlap. Had this tornado occurred just one mile
north of its documented track, it would have resulted in major
impacts to densely populated residential areas as well as numerous
commercial businesses along Route 22. This tornado began west of
the Manor Valley golf course, causing significant tree damage to
both it, the Cloverleaf golf course, and several properties along
Boquet road before crossing PA 66. The tornado intensified as it
then moved across Beaver Run Road, Jobes Road, Crooked Run Road,
and Winter lane, before crossing PA 819. Low end EF-2 damage was
first observed along Jobes road where the tornado descending down
a steep hillside, snapping and uprooting dozens of trees. After
crossing Rt 819, the tornado crossed Orr Rd, producing roof damage
to the Orrco plant, significant tree damage to neighboring homes,
as well as roof and silo damage to a downstream farmstead along
Hannastown Rd. Just northwest of the Orrco building, the survey
revealed an outcropping of mature trees where the vast majority
had been snapped, also yielding low end EF-2 damage. The tornado
continued east-southeast for another couple of miles, steadily
weakening while producing more sporadic tree damage until
dissipating near US 119.
