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.

.DISCUSSION...
FRNTL BNDRY GENERALLY RUNNING PARALLEL TO I-71...FROM CMH SW TO
NORTH OF CINCY AND INTO SOUTHERN INDIANA.  STRONG TSTM HAS FIRED
ALONG OLD CONV BNDRY ACRS SOUTH CNTRL OH AND IS TRACKING THRU SCIOTO
AND PIKE COS ATTM.  LARGER COMPLEX OF TSTMS EXTENDING FROM SW OF IND
INTO SOUTHERN ILLINOIS.  SVR TSTM WATCH UP JUST TO WEST OF FCST AREA.

TOUGH FCST FOR THIS AFTN AS PERSISTENT SC HANGING TOUGH ACRS SRN 1/2
FCST AREA.  A FEW BREAKS HAVE MADE IT INTO WEST CNTRL OH AND NRN
WHITEWATER VLY WITH MORE STABLE ATMOSPHERE.  FOCUSING ON MCS ACRS
WESTERN IND/KY FOR AFTN...AHEAD OF S/WV TRACKING THRU EASTERN
MISSOURI ATTM.  CURRENT RUC/12Z META INDCG S/WV WILL TRACK INTO FCST
AREA THIS AFTN.  GREATEST THREAT FOR TSTMS WILL BE ACRS SRN 1/2 FCST
AREA...WITH TSTM COMPLEX SLATED TO MOVE INTO SE INDIANA AROUND 18Z.
850-300 MB MEAN WIND FLO INDCG E-NE MOVEMENT TO TSTMS.  WITH THIS IN
MIND...AM A LITTLE CONCERNED THAT A FEW SHRA/TSTMS MAY DVLP FARTHER
NORTH ACRS FCST AREA THIS AFTN (INTO I-70 CORRIDOR).  WILL KEEP
HIGHEST POPS ACRS SRN FCST AREA (50 POPS) AND TAILOR BACK TO LO
CHANCE FURTHER NORTH. SC DECK INHIBITING SFC HEATING AND
INSTABILITY...BUT STILL PROGGED TO 1000-1500 J/KG ALONG AND SOUTH OF
OHIO RIVER BY MID AFTN.  850 LLJ INCREASING TO 30-35 KTS WHICH
SHOULD AID IN TSTM DVLPMNT AS WELL.  THREAT FOR SVR DOES EXIST...BUT
THINK SVR STORMS WILL REMAIN ISOLD.  GREATER CONCERN LIES WITH
POTENTIAL FOR HVY RAINS AS PORTIONS OF NRN KY THAT HAVE SEEN 3-5
INCHES OF RAIN THE LAST TWO EVENINGS LOOK TO GET HIT AGAIN.  PWATS
AROUND 1.5 INCHES AND DEWPTS IN U60S SUPPORT THESE THOUGHTS.

KEEPING MSTLY CLDY SKIES ACRS ALL BUT NRN 1/3 FCST AREA THIS AFTN.
TWEAKED AFTN TEMPS A BIT AND ADJUSTED WORDING FOR TABULAR FCST.
WILL KEEP EYE ON SVR POTENTIAL AND HVY RAIN THREAT...WITH 18-23Z THE
MAIN TIMEFRAME FOR CONVECTION ACRS FCST AREA.
