Warm, moist advection during the morning and early afternoon hours of the 10th led to humid and very warm conditions.  Mean-layer CAPE of around 2000 J/kg, highest over eastern Ohio, illustrated the very unstable conditions.  A few discrete thunderstorm cells were able to form over southwest PA initially, with a few hail and wind damage reports.  However, the bulk of the severe weather was the result of the passage of a negatively-tilted upper trough and a strong cold front, which crossed during the late afternoon and evening hours. Bulk shear of 40 to 50 knots and the cold front allowed for the development of a quasi-linear convective system, resulting in widespread reports of wind damage.  Gusts of 70-80 MPH were estimated in some cases, leading to numerous reports of damage to trees and power lines, as well as mostly minor structural damage to roofing and shingles. Mesovortices in the QLCS also led to the development and confirmation of three tornadoes in the NWS Pittsburgh forecast area. The strongest was in Beaver County PA, with EF-2 damage observed.

Thunderstorm Wind in COLUMBIANA, OHIO

Location: ROGERS
Magnitude: 70.00 EG
Property damage: 100.00K
Crop damage: 0.00K
Reported by: NWS Storm Survey

This path was evaluated owing to the presence of a radar-depicted
mesovortex track. Damage along this extensive track was the most
considerable examined today, with abundant tree destruction in the
form of uprooted or snapped hardwood trunks, widespread snapped
large limbs and occasional fascia and shingle damage to single-
family residences. A tree was blown onto an occupied vehicle east
of Rogers, OH early in the swath before wind speed appeared to
increase considerably. Elsewhere along the path, several
outbuildings suffered roofing damage, including a barn in Lawrence
County, where a portion of the roofing structure was removed and
transported downwind among other local damage. Damage to power
poles along the swath appears tied to trees falling on power
lines.
Damage was concentrated in several areas, including the western
and northern sections of East Palestine, the area near Howell
Road/Route 14 area and areas adjacent to the Pennsylvania Turnpike
in Little Beaver and North Beaver Townships of Lawrence County,
PA.
Ultimately this damage was deemed to be non-tornadic but of
considerable intensity. The swath generally paralleled the radar-
depicted mesovortex on its southeast flank, but featured
considerable width and a modestly divergent pattern atypical of
mesovortex tornadoes. Nevertheless, the wind speed along this
swath was of comparable intensity to many tornadoes and over a
broader area, leading to the widespread damage observed.
At its peak over this roughly 11 mile swath examined, damage was
consistent with speed up to 80 mph at times. A vast majority of
the damage examined was consistent with wind of around 70 mph.
It is entirely probable that severe wind continued northeast of
the swath evaluated today, but a coherent swath was no longer
noted, and the radar-depicted mesovortex dissipated hereafter.

Damage along this discontinuous path began in relatively open
terrain southeast of Hanoverton and continued to near Richey
School Road and Route 30 northeast of Hanoverton. The most
concentrated area of damage encountered was along Lindesmith Road,
where a farmstead was impacted by the tornadic wind. In and near
this location, several trees were snapped or uprooted, and several
additional large limbs had been snapped. Also here, sheet metal
roofing from a barn was removed, and two 3000 lb hay wagons were
relocated upwind of their prior location. Damage in this vicinity
likely was a combination of tornadic and non-tornadic wind. Toward
the end of its path, a home showed damage to its fascia. No
evidence of consistent damage was discovered thereafter. Maximum wind
along the path was estimated to be 75 MPH.

Tornado in COLUMBIANA, OHIO

Location: WASHINGTONVILLE
Tornado F-scale: EF0
Property damage: 20.00K
Crop damage: 0.00K
Reported by: NWS Storm Survey

A brief tornado was confirmed in northern Columbiana County
following a survey of damage in the Leetonia/Washingtonville area.
Damage began just north of the Leetonia High School and was most
concentrated along Leetonia Road, where numerous trees were
snapped or uprooted. Minor fascia damage also was noted in this
area.
The circulation then weakened as it progressed northeast, with
tree damage continuing to the county line, where debris evidence
seemed to end abruptly. NWS Pittsburgh observed no evidence of
wind damage continuing into Mahoning County, which is coincident
with a weakening trend in the radar-depicted circulation.
Damage earlier in the circulation's track across Salem Township was
sporadic and did not prove to be conclusively tornadic.
At its peak, tree damage was consistent with wind speeds of 70-75
mph near the beginning of the swath along Leetonia Road. The
tornado was very narrow and brief, and additional wind damage just
south and east of the tornado likely was caused by enhanced
straight-line wind associated with the tornado's parent mesovortex
and rear-inflow surge.
