Cow counts a report within 15 km of the polygon while the warning was in force: a tornado for a tornado warning; hail of 1 inch or more, a gust of 58 mph or more or wind damage for a severe thunderstorm warning; a flash flood report for a flash flood warning.
The nearest sounding before it
Pittsburgh, PA (KPIT), launched 00:00Z, 6.9 hours before the alert went out and 149 km from the middle of its area. This is the routine balloon launch nearest before it, the air the forecaster had in hand, not a measurement taken for the alert.

.KEY MESSAGES...
1) Flash flooding will be the main concern over the next 48
hours. Training thunderstorms can quickly lead to flash
flooding, especially in areas that already saw heavy rainfall
over the past week.
&&
.DISCUSSION...
KEY MESSAGE 1...
Training thunderstorms are currently causing flash flooding
across portions of southeast Ohio. These training thunderstorms
are being caused by mid- level vorticity flowing on the
northern periphery of a large area of high pressure, in
combination with a stationary surface boundary. The atmosphere
remains very moist, with precipitable water values ranging from
2.00 to 2.25 inches. The main concern through daybreak Monday
will be flash flooding across southeast Ohio counties.
The aforementioned stationary front will lift northeastward
into Pennsylvania after daybreak with the entire forecast area
transitioning into the warm sector. Additional rounds of
showers and thunderstorms are expected area-wide Sunday through
Sunday night as additional mid-level waves track across the
forecast area. It's difficult to pinpoint exactly where the main
focus of thunderstorm development will be during this
timeframe, as new development will be triggered by thunderstorm
outflow boundaries from previous complexes. We will be
monitoring trends closely. In addition to flooding, severe
thunderstorms will also be possible Sunday with any
thunderstorms. 1,500 J/kg of MLCAPE and 30-35 kts of 0-6km bulk
shear will allow for organized thunderstorm development that
could turn severe at times.
A cold front will finally cross the forecast area from northwest
to southeast Monday afternoon. This will bring high pressure and
the return of much-needed drier weather behind it.
Thunderstorms will return to the forecast Thursday and Friday as
a trough and another area of low pressure approach from the
west.
&&
.AVIATION /06Z SUNDAY THROUGH THURSDAY/...
At the time of this writing, conditions remain mostly VFR.
However, lowering ceilings are expected later this morning, with
MVFR and IFR restrictions added into the 06Z TAF package.
Showers are possible early this morning across KPKB and KCKB
with MVFR visibility restrictions possible. Ceilings should
improve between 12Z and 15Z. Additional thunderstorms will
develop Sunday afternoon and evening, and downpours can bring
visibility restrictions. Confidence in exactly where these
thunderstorms will develop is low, so VCTS has been added to
most TAF sites Sunday afternoon.
FORECAST CONFIDENCE AND ALTERNATE SCENARIOS THROUGH 06Z MONDAY...
FORECAST CONFIDENCE: MEDIUM
ALTERNATE SCENARIOS: Ceiling restrictions early this morning may
vary. Timing and location of thunderstorms and associated
impacts Sunday afternoon/evening will vary.
