What was reported inside it

Time	Report	Where	Remark
Jun 23, 5:10 PM EDT	HAIL 0.75	Bartlett, OH

Local storm reports filed while the alert was in force, from inside its polygon or its counties.

Did it verify

Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this severe thunderstorm warning while it was in force. That is not proof nothing happened: reports are thin where few people live.

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 12:00Z, 9.0 hours before the alert went out and 156 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.

OHIO...AHEAD OF COLD FRONT. COLD FRONT...CURRENTLY LOCATED OVER
CENTRAL OHIO...PROGGED TO MOVE THROUGH AND CLEAR CWA BY 03Z. MODELS
BRING H5 TROUGH BY 12Z. DEEP SHEAR AND CAPE NOT THAT IMPRESSIVE OVER
AREA. CONVECTION THAT FORMS SHOULD STAND STRAIGHT UP. STEEP MID

ONGOING FCST FOR MINT TONIGHT AGREES WELL WITH LATEST GUIDANCE...SO
DID NOT STRAY TOO FAR. GENERALLY FOLLOWED LMOS AND MET FOR MAXT ON
TUESDAY AS MAV SEEMS TOO WARM ACROSS THE BOARD.

&&

.SHORT TERM /TUESDAY NIGHT THROUGH THURSDAY NIGHT/...
THE MODELS ARE IN DECENT AGREEMENT FOR THE MID RANGE PERIOD AS
INITIALLY THE ATMOSPHERE REMAINS DRY SO HAVE KEPT CLOUDS DOWN TO A
MINIMUM TUESDAY NIGHT WITH DRY WEATHER.  ON WEDNESDAY...AS THE FRONT
BEGINS TO TURN AROUND AND HEAD BACK NORTH...THE CLOUDS WILL BEGIN TO
INCREASE...BUT SHOULD BE MAINLY HIGH CLOUDS.  AS THE FRONT GETS
CLOSER WED NIGHT...SHORTWAVE ENERGY ROTATING OVER THE TOP OF THE
FRONT ON THE NORTHERN SIDE OF THE DEVELOPING SERN US RIDGE COULD
PRODUCE AN AREA OF SHOWERS.  THE GFS IS A LITTLE MORE PROGRESSIVE
WITH THE WAVE AND ALLOWS IT TO TURN A LITTLE MORE SE THAN THE SLOWER
NAM.  AT THIS STAGE LIKE THE GFS HANDLING OF THE SHORTWAVE SO HAVE
BROUGHT THE CHANCE POPS WED NIGHT INTO THURSDAY MORNING DOWN TO
CRW/HTS LINE AND THEN LIFT IT NORTHEAST AWAY FROM THE AREA THURSDAY
MORNING.  ONCE THE FRONT AND SHORTWAVE CLEARS...THE RIDGING OVER THE
SE WILL BEGIN TO BUILD NORTHWARD...WHICH WILL ALLOW THE TEMPERATURES
AND HUMIDITY TO BEGIN TO RISE.

FOR TEMPERATURES...LEANED TOWARD THE MET EARLY IN THE PERIOD
ESPECIALLY FOR WED AND WED NIGHT AS THE MAV HAS BEEN GIVE TOO LARGE
OF A DIURNAL OF LATE.  ALSO THE 850 MB TEMPERATURES OFF BOTH MODELS
WOULD SUPPORT THE COOLER MET NUMBERS.  FOR THURSDAY AND THURSDAY
NIGHT THE MEX NUMBERS LOOKED REASONABLE.

&&

.LONG TERM /FRIDAY THROUGH MONDAY/...
INITIALLY WILL BEGIN THE EXTENDED WITH A STRONG SERN US RIDGE IN
PLACE AND THEN GRADUALLY EXPECT A STRONGER TROUGH/CLOSED LOW OVER
THE NRN PLAINS AND GREAT LAKES TO KNOCK THE RIDGE DOWN AND PUSH A
FRONT THROUGH THE REGION.  THE OPERATIONAL ECMWF AND GFS BOTH SHOW
THIS ENHANCED TROUGHING FOR THE SAT NIGHT/SUNDAY TIME FRAME.  HPC
WAS A LITTLE TAMER WITH THE TROUGH AS THE ENSEMBLE MEMBERS WERE MORE
PROGRESSIVE AND DID NOT PUSH THE COLD FRONT AS FAR SOUTH...GETTING
TOWARD THE NC/VA BORDER BY SUNDAY MORNING...WHICH IS
CLIMATOLOGICALLY FAVOR.  FOR NOW HAVE FOLLOWED MORE ALONG THE HPC
SCENARIO FOR THE PERIOD.  HAVE TRIED TO DOWN PLAY THE DAYTIME
CONVECTION ON FRIDAY AS THE MOISTURE LOOKS TO BE LACKING AND WITH
OUT MUCH OF A KICKER NOT ANTICIPATING MUCH ACTIVITY ON FRIDAY.  AS
THE FRONT ARRIVES...AND THE MODELS ARE STRUGGLING WITH WHEN THE
FRONT ARRIVES FROM SAT AFTERNOON INTO EARLY SUNDAY MORNING...EXPECT
MORE ORGANIZED AREA OF SHOWERS AND THUNDERSTORMS TO DEVELOP.

DRIER CONDITIONS RETURN THROUGH MONDAY.
