Survey Summary:
A supercell thunderstorm, embedded within a broken line of
thunderstorms, produced a series of tornadoes as it tracked
across eastern Ohio, the northern West Virginia panhandle, and
western Pennsylvania during the early morning hours on
Wednesday.

The most significant tornado developed across northwest
Jefferson county Ohio around 12:54 AM, along county highway 55.
Initially, it snapped and uprooted numerous hardwood trees. As
the tornado moved east along highway 55, it took roofs off
multiple homes, overturned and tossed a mobile home, and shifted
a single family residence off its foundation. The twister then
moved into the center of Irondale, where numerous hardwood and
softwood trees were uprooted and snapped, all consistent with EF-
2 damage. The tornado was able to descend and climb through steep
terrain, with hundreds of trees observed damaged or destroyed
from the highway 55 ridge line and along a steep several hundred
foot escarpment. Several trees fell onto homes causing damage. A
metal building system lost its roof and part of the side walls.
The tornado continued to move east causing downed trees along
state route 213 in Hammondsville eastward to the Ohio river.After
crossing the Ohio River south of Wellsville, the tornado reached
peak intensity as it crossed the community of Fairhaven several
miles south of Chester, West Virginia. Extensive tree and
structural damage was observed along International Drive and
Locust Hill Road.  There were multiple homes that lost their
entire roof and sustained damage to side walls.  Numerous barns
and outbuildings were completely destroyed.  All mature hardwood
and softwood trees, some well over 100 years old, were snapped
with a few lingering hardwood trees that were debarked. A high-
end EF2 rating of 130 mph was observed in this location.
Pittsburgh Doppler radar velocity signatures in this area were at
the high end of those observed historically, coupled with a
significant debris signature aloft. Further damage was observed
across Route 8 extending back uphill into the next ridge line,
where an auto repair metal outbuilding was destroyed, along with
damage sustained to several vintage automobiles. The adjacent
property suffered loss of roofing, a porch, and an addition. The
tornado finally crossed the Pennsylvania line into far western
Beaver county, where the last indications of damage was observed
along Gas Valley Road where several trees were uprooted.

The National Weather Service would like to thank Hancock County
Office Emergency Services, Jefferson County Department of Public
Safety, and the Irondale Fire Department for their assistance.

This is the FIRST recorded tornado in Hancock County West
Virginia, and the 9th documented tornado in Jefferson County Ohio.
The most recent one there was October 21 2021 and was rated an
EF0. This was Beaver County PA`s first tornado since
October 21, 2021 as well.

Survey Summary:
A storm survey performed by the National Weather Service
confirmed that a brief EF-1 tornado, with maximum winds of
105 MPH, occurred near Aten Road in Findlay Township, just west
of I-376 and adjacent to the Pittsburgh International Airport.
The tornado touched down north of Aten Road, where a trailer
on blocks in a parking lot was overturned, with some tree
damage nearby. The tornado then progressed southeast, snapping at
least 15-20 trees along the northern side of Aten Road. This area
represented the strongest damage, where the 105 MPH wind was
assigned. A nearby outbuilding lost a metal roof in several
pieces. One portion fell on the interstate, while another blew
over the interstate and landed roughly a quarter-mile downwind.
The tornado caused additional tree damage near the Edgeworth
Security and Marriot hotel buildings.  The tornado likely then
lifted, as no other appreciable damage was noted other than the
previously noted roof pieces that were blown downstream.

Survey Summary:
The team observed tree damage along Matson Road where the tornado
touched down initially. The damage in this area would indicate and
EF0 tornado, with a couple of trees snapped more than halfway up
from their base. The team noticed more significant damage starting
at Austraw Road, where several trees were either uprooted, or
their trunks were snapped halfway up. A small cattle shelter also
collapsed in this area.

The tree damage continued up and down the hillside to the east
toward McCurdy Trail and Berkeley Road. Concentrated damage
occurred around two homes in this area, mainly to trees. A mix of
very large hard and softwood trees was snapped low on the trunk
and up high, while others were uprooted. Another area of
concentrated tree damage was noted in the fields east of Berkeley
down to Coalpit Creek, where the tornado lifted. The team also
observed that some trees in this area were stripped of their bark.

End Lat/Lon:            40.1602 / -82.1166

Survey Summary:
A severe thunderstorm exhibiting cyclic tornadic characteristics
produced a brief EF1 tornado in northern Muskingum County. The
first tornado damage was noted around a lake just off of Wise Road
where a swath of softwood trees were snapped at the trunks and
uprooted. The tornado continued to the east-northeast where it
impacted a home and two outbuildings just downstream. A
significant portion of the first outbuilding`s roof was removed
and walls on two sides of the building collapsed. The home saw
significant window damage with glass in most windows completely
shattered and pieces of wood and roofing material thrown into the
house creating exterior damage to siding. A significant portion of
the roof was removed with roofing material thrown around the
property. Several chunks of broken 2x4s, presumably from the
outbuilding, were thrown nearly 100 yards and impaled into the
ground next to the house. The tornado collapsed half of a
secondary outbuilding and shifted the remaining standing half off
of its foundation. Just beyond the house and outbuildings,
additional tree damage was noted with large and healthy hardwood
trees twisted, uprooted, and snapped at the trunks. It was this
damage that resulted in the maximum wind 105 mph EF1 rating. Just
next to the trees, a wood light pole was snapped at its base. The
tornado then lifted as it exited the property toward Wise Road as
no additional damage was noted downstream in a wide coverage area
of trees.

.Coshocton County, Ohio Tornado...

Rating:                 EF1
Estimated Peak Wind:    105 mph
Path Length /statute/:  0.10 miles
Path Width /maximum/:   197 yards
Fatalities:             0

End Lat/Lon:            40.1785 / -82.0063

Survey Summary:
The same severe thunderstorm then produced another brief EF1
tornado as it moved east-northeast into southern Coshocton County.
Damage was noted to a home, outbuilding, and trees just off of
County Road 439. It`s believed that the tornado touched down very
close to the house itself with the bulk of the damage occurring on
the northeast side of the house, opposite of the parent
thunderstorm`s southwest to northeast motion. The outbuilding had
its roof removed and most of its walls completely collapsed save
for part of one side that remained standing. The tornado removed
the entire metal roof throwing it in pieces several hundred yards
downstream into a field as well as upstream where two pieces were
wrapped around the top of a tree. While most walls remained
standing, the back side of the home was torn off and laid on the
ground. It was this damage that the highest EF1 wind speed of 105
mph was observed. Insulation from this part of the home was thrown
all over the property and plastered on all sides of the home.
Several healthy softwood trees were uprooted in the backyard.

The National Weather Service would like to thank both Muskingum
and Coshocton County Emergency Management for their assistance
with this damage survey.
