The archived warnings, watches and discussions in force at that minute are drawn over the scan, this one among them.

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

Cncnati-Daytn, OH (KILN), launched 12:00Z, 9.5 hours before the alert went out and 124 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.

Area forecast discussion, Jun 17, 5:14 PM EDT, 15 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE WILMINGTON OH
514 PM EDT FRI JUN 17 2011

.SYNOPSIS...
A WEST TO EAST ORIENTED FRONT WILL OSCILLATE ACROSS THE REGION
THROUGH THE WEEKEND AS WAVES OF LOW PRESSURE RIDE ALONG IT.

&&

.NEAR TERM /UNTIL 6 AM SATURDAY MORNING/...
SCATTERED THUNDERSTORMS HAVE DEVELOPED IN CENTRAL OHIO ALONG A
WEAK BOUNDARY. WITH PLENTY OF CAPE THESE SEVERAL OF THESE STORMS
PRODUCED SEVERE HAIL. ACTIVITY SEEMS TO BE DECREASING IN INTENSITY
BUT THERE COULD STILL BE A FEW SEVERE CELLS IN THAT AREA.

OTHER CONCERN IS MCS MOVING INTO SOUTHWESTERN INDIANA AND CENTRAL
KENTUCKY. THE STRONGEST PART OF THIS COMPLEX SHOULD PASS JUST SOUTH
OF THE FORECAST AREA. BUT PRECIPITATION SHIELD MAY STILL AFFECT
SOUTHWESTERN ZONES FOR A TIME EARLY THIS EVENING.

APPEARS THAT IT WILL BE A GENERALLY QUIET OVERNIGHT PERIOD. BUT
GUIDANCE STRONGLY SUGGESTS ANOTHER MCS MAY BE APPROACHING THE
WESTERN ZONES LATE TONIGHT. SO CHANCE POPS WORK BACK IN TOWARDS
DAYBREAK.

FAVORED WARMER MOS GUIDANCE FOR OVERNIGHT LOWS.

&&

.SHORT TERM /6 AM SATURDAY MORNING THROUGH SATURDAY NIGHT/...
MOST 12Z GUIDANCE IS FOCUSED IN ON AN MCS MOVING INTO THE
FORECAST AREA DURING THE MORNING. THIS IS FORECAST TO TRACK EAST
THROUGH THE AFTERNOON AND INTO THE EVENING. EVOLUTION OF THE
SYSTEM IS UNCERTAIN BUT GIVEN MODEL SOLUTIONS FELT THAT LIKELY
POPS ARE WARRANTED. ACTIVITY SHOULD DIMINISH LATE SATURDAY
EVENING.

HIGHS WILL BE HIGHLY DEPENDENT ON HOW MUCH SUN GET THROUGH BEFORE/
AFTER/BETWEEN STORMS. JUST WENT BETWEEN GFS MOS AND NAM MOS. LOWS
SHOULD REMAIN MILD AND LEANING TOWARDS WARMER GUIDANCE AGAIN SEEMS
MOST PRUDENT.

&&

.LONG TERM /SUNDAY THROUGH FRIDAY/...
BOTH THE ECMWF AND THE GFS BRING A SHORT WAVE THROUGH THE FA ON
SUNDAY.  THE NAM IS SLIGHTLY SLOWER WITH THIS FEATURE AND IS
OVERDOING THIS FEATURE AS WELL.  WENT CLOSER TO THE ECMWF AND GFS
SOLUTIONS.  THIS FEATURE WILL ENHANCE PRECIPITATION CHANCES ACROSS
THE AREA AND THEREFORE INCREASED PRECIPITATION CHANCES ON SUNDAY.
SEVERE WEATHER WILL BE POSSIBLE ON SUNDAY AND WITH HIGH PW VALUES
HEAVY RAINFALL WILL ALSO BE A CONCERN.  A WARM FRONT WILL LIFT NORTH
ACROSS THE AREA SUNDAY NIGHT INTO MONDAY AND THEREFORE CONTINUED
PRECIPITATION CHANCES DURING THIS TIME WITH FRONTAL BOUNDARY IN THE
VICINITY.  PRECIPITATION CHANCES WILL THEN TAPER OFF DURING THE
AFTERNOON AND EVENING HOURS ON MONDAY.  TUESDAY WILL BE DRY WITH THE
FRONTAL BOUNDARY NORTH OF THE AREA.  WITH FRONT NORTH OF THE AREA
AND NO PRECIPITATION ACROSS THE FA EXPECT THIS TO BE THE WARMEST DAY
OF THE LONG TERM WITH HIGHS IN THE 90S.  A COLD FRONT WILL BEGIN TO
APPROACH THE REGION ON WEDNESDAY AND WILL MOVE THROUGH THE AREA ON
THURSDAY.  INCREASED PRECIPITATION CHANCES DURING THIS TIME TO
ACCOUNT FOR THIS.  HIGH PRESSURE WILL BUILD INTO THE AREA FOR
FRIDAY.

&&

.AVIATION /21Z FRIDAY THROUGH WEDNESDAY/...
CU ARE BEGINNING TO FILL IN SOME...ESPECIALLY ALONG THE A BOUNDARY
THAT IS SITUATED ACROSS CENTRAL OHIO. AS WE CONTINUE TO DESTABILIZE
THROUGH THE REST OF THE AFTERNOON...EXPECT CU FIELD TO BECOME MORE
DEVELOPED WITH THE POSSIBILITY OF SOME SCATTERED THUNDERSTORM
DEVELOPMENT. WOULD THINK THE BEST CHANCE FOR THIS WOULD BE ALONG
THE BOUNDARY AND THUS MAINLY AFFECTING THE KCMH/KLCK TAFS.
DIURNALLY ENHANCED CU AND ANY PCPN SHOULD THEN TAPER OFF THIS
EVENING. IT LOOKS LIKE THE POSSIBILITY STILL EXISTS FOR AN MCS TO
DEVELOP OFF TO OUR WEST LATER TONIGHT. HOWEVER...THE 12Z MODELS
ARE A LITTLE FARTHER TO THE SOUTHWEST WITH THE BETTER FORCING SO
THINK KCVG/KLUK WOULD HAVE THE HIGHEST CHANCE OF BEING AFFECTED
BY THIS LATE IN THE PERIOD.

OUTLOOK...OCCASIONAL CHANCES FOR THUNDERSTORMS WILL CONTINUE
THROUGH SUNDAY NIGHT.

WEATHER THREATS.

.DAYS TWO THROUGH SEVEN...SATURDAY THROUGH THURSDAY.

A FRONTAL BOUNDARY WILL OSCILLATE ACROSS THE REGION THROUGH THE
WEEKEND AS WAVES OF LOW PRESSURE RIPPLE ALONG IT. THIS SETUP WILL
BRING ROUNDS OF SHOWERS AND THUNDERSTORMS. THE POTENTIAL EXISTS
FOR SEVERE THUNDERSTORMS TO OCCUR OVER THE WEEKEND. HOWEVER...THE
TIMING AND EXTENT IS STILL UNCERTAIN AT THIS TIME. IF SEVERE
WEATHER MATERIALIZES...DAMAGING WINDS AND LARGE HAIL CAN BE
EXPECTED. IN ADDITION...A VERY MOIST AIRMASS WILL BE IN PLACE.

WEATHER SITUATION.
