The Cincinnati radar (KILN), 140 km from the middle of the area, began a volume at 22:40 UTC, the scan nearest the moment this went out.

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.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CLEVELAND OH
ISSUED BY NATIONAL WEATHER SERVICE BUFFALO NY
622 PM EDT TUE MAY 26 2015

.SYNOPSIS...
HIGH PRESSURE WILL REMAIN CENTERED OFF THE EAST COAST AND LOW
PRESSURE WILL MOVE NORTHEAST ACROSS THE WESTERN GREAT LAKES
THROUGH TONIGHT. A WEAKENING COLD FRONT WILL REACH NORTHWEST OHIO
WEDNESDAY AFTERNOON. HIGH PRESSURE WILL REGAIN CONTROL ACROSS THE
REGION FOR THURSDAY AND THE FIRST PART OF FRIDAY.

&&

.NEAR TERM /THROUGH WEDNESDAY/...

A SEVERE THUNDERSTORM WATCH IS NOW IN EFFECT FOR THE ENTIRE OHIO
PORTION OF THE CWA. RADAR AND SATELLITE IMAGERY EARLY THIS EVENING
SHOWING NUMEROUS BROKEN BANDS OF STORMS MOVING NORTHEAST ACROSS
THE WESTERN HALF OF OHIO. MOST OF THE STORMS...ESPECIALLY THE
EASTERN STORMS...ARE REMAINING SUB-SEVERE WITH MARGINAL SHEAR AND
INSTABILITY ACROSS CENTRAL OHIO. A CORRIDOR OF SOMEWHAT BETTER
SEVERE WEATHER PARAMETERS IS EVIDENT ACROSS WESTERN OHIO AHEAD OF
A CONVECTIVELY AUGMENTED MID LEVEL SHORTWAVE AND PRE-FRONTAL
TROUGH. 0-6KM SHEAR IN THIS AREA IS STILL MARGINAL AT AROUND 30
KNOTS...WITH SBCAPE OF AROUND 1500J/KG.

WITH SUCH MARGINAL PARAMETERS...THE BETTER SEVERE WEATHER
POTENTIAL WILL REMAIN TIED TO THE ALREADY PRESENT CONVECTIVE COLD
POOLS WHERE STORM GENERATED SHEAR AND MESOSCALE FORCING IS
STRONGER AND SUPPORTIVE OF SEVERE WIND AND HAIL. THE MOST NOTABLE
OF THESE CONVECTIVE COLD POOLS MOVED THROUGH FINDLAY WITH A 61
KNOT GUST. THIS CONVECTIVE LINE IS HEADED TOWARDS SANDUSKY AND THE
ISLANDS OF WESTERN LAKE ERIE. ANOTHER CONVECTIVE COLD POOL AND
BOWING LINE SEGMENT TO THE WEST OF COLUMBUS WILL MOVE
NORTHEASTWARD INTO THE CWA IN THE NEXT HOUR OR SO.

FOR THE CLEVELAND METRO AREA THE INITIAL SHOWERS AND STORMS WILL
ARRIVE WITHIN THE NEXT HOUR AND ARE LIKELY TO REMAIN SUB-SEVERE
INITIALLY. SEVERE RISK FOR THE CLEVELAND AREA WILL BE MID TO LATE
EVENING IF THE BOWING SEGMENTS ACROSS WESTERN OHIO CAN BE
MAINTAINED THAT LONG.

FARTHER EAST ACROSS NORTHEAST OHIO AND NORTHWEST PA VISIBLE
SATELLITE IMAGERY SHOWING A RELATIVELY FLAT CUMULUS FIELD WITH
LITTLE POTENTIAL FOR ANY SHOWER OR THUNDERSTORM DEVELOPMENT UNTIL
LATE THIS EVENING.

CONVECTIVE THREAT WILL LIKELY DIMINISH LATER TONIGHT AS THE PRE-
FRONTAL TROUGH MOVES ACROSS EASTERN SECTIONS OF THE AREA AS
INSTABILITY WANES BUT THERE STILL COULD BE SOME LINGERING
CONVECTION THROUGH THE NIGHT...AS IT APPEARS THE UPPER SYSTEM WILL
TRY TO PULL ANOTHER WEAKER LOBE OF VORTICITY THROUGH THE REGION
WHILE THE MID LEVEL COOL POOL SLIDES THROUGH SOUTHERN GREAT
LAKES/OHIO VALLEY. TEMPERATURES WILL STAY MILD IN THE LOWER TO MID
60S AS A SOUTHERLY FLOW CONTINUES AHEAD OF THE UPSTREAM COLD
FRONT.

THE REGION WILL REMAIN WELL WITHIN THE WARM SECTOR WEDNESDAY AHEAD
OF APPROACHING COLD FRONT. CONVECTIVE POTENTIAL WILL LIKELY BE TIED
TO THE DIURNAL CYCLE WITH WITH GREATEST COVERAGE OF SHOWERS AND
THUNDERSTORMS DURING THE AFTERNOON. PERSISTENCE IN THE THERMODYNAMIC
PROFILES SUGGESTS SIMILAR INSTABILITY PARAMETERS AS TODAY WITH
MLCAPE VALUES GENERALLY 1000-1500 J/KG. THE SURFACE BOUNDARY/WEAK
COLD FRONT IS EXPECTED TO WORK THROUGH THE AREA DURING THE AFTERNOON
WHICH WILL PROVIDE SUFFICIENT FORCING. SHEAR PROFILES LOOK A BIT
WEAKER THAN TODAY THEREFORE SEVERE THREAT WILL BE RATHER LIMITED. IT
WILL BE ANOTHER WARM DAY WITH HIGHS IN THE LOWER TO MID 80S.

&&

.SHORT TERM /WEDNESDAY NIGHT THROUGH THURSDAY NIGHT/...
A POTENT SHORTWAVE WILL LIFT FROM NORTHERN LOWER MICHIGAN ACROSS
EASTERN ONTARIO WEDNESDAY NIGHT...FORCING A SURFACE COLD FRONT
ACROSS NORTHERN OHIO. EXPECT SHOWERS AND THUNDERSTORMS TO TRACK FROM
WEST TO EAST ACROSS THE FORECAST AREA ALONG/JUST AHEAD OF THE
SURFACE FRONTAL BOUNDARY. WHILE INSTABILITY IS NOT EXPECTED TO BE
PARTICULARLY DEEP WITH SFC-BASED CAPES RUNNING AROUND
1000J/KG...BULK SHEAR WILL BE AROUND 30KTS AND THERE WILL BE GOOD
SFC CONVERGENCE/UPPER LEVEL FORCING TO FOCUS CONVECTION...SO EXPECT
A MARGINAL SEVERE WIND THREAT ACROSS THE AREA.

CONVECTION WILL TAPER OFF FROM WEST TO EAST WED NIGHT AS THE FRONT
CROSSES THE AREA. HIGH PRESSURE WILL BUILD IN BEHIND THE
FRONT...PROVIDING WHAT SHOULD BE A MOSTLY SUNNY AND RAIN-FREE THE
AREA ON THURSDAY. THE FAIR WEATHER SHOULD PERSIST THROUGH THURSDAY
NIGHT AS THE SURFACE HIGH SETTLES ACROSS THE NORTHEASTERN U.S. AND
MID-ATLANTIC STATES.

AS HIGH PRESSURE CONSOLIDATES OFF THE EAST COAST ON FRIDAY...RETURN
FLOW WILL ONCE AGAIN TAKE HOLD ACROSS THE MIDWEST AND OHIO VALLEY.
THIS WILL PUSH HIGHS BACK INTO THE MID 80S WITH SURFACE DEWPOINTS
SURGING BACK INTO THE MID-60S. AS SUCH...WE MAY SEE ENOUGH
INSTABILITY DEVELOP TO OVERCOME A FAIRLY WEAK CAP AND FIRE OFF A FEW
SHOWERS AND PERHAPS A RUMBLE OF THUNDER OR TWO IN THE
AFTERNOON...MAINLY WEST OF I-71 WHERE DEEPER MOISTURE/INSTABILITY
WILL BE FOUND. THE EASTERN PORTIONS OF THE FORECAST AREA SHOULD
REMAIN CLOSE ENOUGH TO THE DEPARTING RIDGE TO REMAIN DRY THROUGHOUT
THE DAY. ANY CONVECTION SHOULD QUICKLY DISSIPATE AFTER SUNSET WITH
THE LOSS OF DIURNAL INSTABILITY. OTHERWISE IT WILL BE A DRY...BUT
STICKY SUMMER NIGHT ACROSS NORTHERN OHIO AS DEWPOINTS WILL REMAIN
LOCKED IN THE MID-60S...KEEPING LOWS IN THE MID TO UPPER 60S.

&&

.LONG TERM /FRIDAY THROUGH TUESDAY/...
CURRENT GUIDANCE IS IN DECENT AGREEMENT THAT THE COMING WEEKEND
WILL BE UNSETTLED ACROSS MUCH OF THE BUCKEYE STATE AS A COLD FRONT
DROPPING OUT OF THE UPPER GREAT LAKES ADVANCES ACROSS OHIO
SATURDAY. SHOWERS AND THUNDERSTORMS WILL LIKELY ACCOMPANY THE
PASSAGE OF THE COLD FRONT SATURDAY INTO SATURDAY NIGHT. PREVIOUS
GUIDANCE STALLED THE FRONT OUT ACROSS OHIO...HOWEVER 12Z RUNS HAVE
BEEN MUCH MORE AGGRESSIVE IN PUSHING THE FRONT ALL THE WAY
THROUGH. FOR NOW...WILL STICK CLOSE TO CONTINUITY AND AT LEAST
MAINTAIN CHANCE POPS ON SUNDAY INTO MONDAY.

REGARDING TEMPERATURES...READINGS IN THE LOWER 80S SATURDAY WILL
GIVE WAY TO COOLER READINGS IN THE WAKE OF THE COLD FRONTAL PASSAGE
WITH HIGHS IN THE 70S THROUGH THE REST OF THE PERIOD AS THE FRONT
EITHER STALLS OUT...LEADING TO CLOUDY AND HENCE COOLER
CONDITIONS...OR PUSHES COMPLETELY THROUGH...ALLOWING COOLER AND
DRIER AIR TO ADVECT ACROSS THE REGION. LOWS SHOULD RUN IN THE UPPER
50S...NEAR TO OR JUST ABOVE CLIMATOLOGY.

&&

.AVIATION /18Z TUESDAY THROUGH SUNDAY/...
ORGANIZED SHOWERS AND THUNDERSTORMS MOVING INTO THE WESTERN
PORTION OF THE AREA WILL CONTINUE TO SPREAD EAST THIS EVENING WITH
LOCAL/BRIEF MVFR/IFR CONDITIONS. STORMS WILL REACH KCLE SHORTLY
AFTER 23Z...WITH A FEW MORE SCATTERED STORMS LASTING THROUGH 04Z.
SOME STORMS MAY PRODUCE GUSTY WINDS AND HAIL THROUGH MID TO LATE
EVENING.

WINDS WILL REMAIN OUT OF THE SOUTH THIS EVENING AND WILL BE
BREEZY WITH GUSTS TO AROUND 25 KNOTS AT SOME LOCATIONS INTO THE
EARLY EVENING.

SOME AREAS OF IFR CEILINGS COULD DEVELOP LATE TONIGHT AS THE
DEEPER MOISTURE STRIPS AWAY.

.OUTLOOK...NON VFR POSSIBLE WEDNESDAY IN SCT SHRA AND TSRA...THEN
RETURNING AGAIN ON SATURDAY AND SUNDAY.

&&

.MARINE...
SOUTHERLY WINDS WILL CONTINUE ON LAKE ERIE INCREASING TO 10 TO 20
KNOTS OVERNIGHT. SCATTERED THUNDERSTORMS ARE POSSIBLE THIS
EVENING IN THE OHIO WATERS OF LAKE ERIE...SOME OF WHICH COULD BE
STRONG TO SEVERE WITH LOCALLY HIGHER WINDS AND WAVES.

WINDS WILL SHIFT TO THE NORTHEAST AND EAST ON THURSDAY AS HIGH
PRESSURE BUILDS IN BEHIND A WEAK COLD FRONT. SOUTHERLY WINDS WILL
DEVELOP AGAIN ON FRIDAY...SHIFTING TO THE NORTHEAST BEHIND A
STRONGER COLD FRONT LATE SATURDAY. SMALL CRAFT ADVISORIES MAY BE
NEEDED FOR THE ONSHORE FLOW DURING THE SECOND HALF OF THE WEEKEND.
