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, Jul 10, 1:58 PM EDT, 1 hour 11 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CLEVELAND OHIO
158 PM EDT MON JUL 10 2006

.AVIATION(18Z-18Z)...
COLD FRONT EXTENDED FROM WESTERN LAKE ONTARIO TO
NORTHERN INDIANA WILL CONTINUE MOVING SLOWLY SOUTHEAST
AND BECOME NEARLY STATIONARY ACROSS CENTRAL OHIO. TSTMS WILL
CONT TO DEVELOP THIS AFTERNOON AND EVENING.

AFTER FROPA TAKES PLACE...RESIDUAL SC AND AC AND LOWER VSBYS
WILL DEVELOP ACROSS THE AREA OVERNIGHT. CONDS FOR TNGT LOOKS
LIKE MVFR AND POSSIBLY SOME IFR CONDS IN CLDS AND VSBYS.

&&

.SHORT TERM UPDATE (THIS AFTERNOON)...
RADAR AND SAT SHOWING LINE OF SHOWERS AND THUNDERSTORMS EXTENDING
FROM WEST TO EAST ACROSS MUCH OF FORECAST AREA. LATEST OBS SHOWING
COLD FRONT MOVING INTO NW OH AT THIS TIME. HOWEVER...WATER VAPOR
IMAGE SHOWING VERY NICE VORT MAX DIVING SOUTHEAST OVER LAKE HURON
WHICH WILL NEED TO WATCH THROUGH THE AFTERNOON. HOWEVER...LOOKS AS
THOUGH VORT MAX WILL MOVE OVER FAR NORTHEASTERN PORTIONS OF THE
FORECAST AREA.

ALSO PLACED SEVERE THUNDERSTORM WATCH IN ZONES UNTIL THIS EVENING.
RUC AND NAM SHOWING SOME INCREASE IN INSTABILITY ACROSS WESTERN AND
SW PORTIONS OF THE FORECAST AREA INTO THE AFTERNOON HOURS...SO
LOOKING FOR THUNDERSTORMS TO CONTINUE AHEAD OF FRONT THROUGH THE
AFTERNOON AND INTO EARLY EVENING HOURS.

&&

.SHORT TERM(TODAY THRU WED)...
LOOKS LIKE MOST OF AREA WILL SEE A PRETTY GOOD SHOT OF RAIN DURING
THE PERIOD AS HUMID AIRMASS GETS ESTABLISHED OVER REGION.  FIRST
CONCERN IS POTENT S/WAVE SET TO DIVE SE ACROSS NWRN PA LATER TODAY.
THIS FEATURE CURRENTLY LOCATED NEAR THE SOO AND SHOWING UP NICELY ON
WATER VAPOR IMAGERY.  AREA OF CONVECTION HAS DEVELOPED IN ADVANCE OF
VORT AND IS CURRENTLY MOVING ESE ACROSS LOWER MI.  THIS ACTIVITY
CONTS TO WEAKEN BUT COULD MAKE IT TO KERI AROUND DAYBREAK. AT SAME
TIME CDFNT OVER LOWER MI WILL CONT TO SAG S.  THIS FRONT WILL CROSS
INTO FORECAST AREA LATER THIS AM.  DEWPOINTS SHOULD POOL AHEAD OF
THIS FRONT AND EXPCT SHRA AND TSRA TO DEVELOP AS IT MOVES THRU.
LAPSE RATES WILL STEEPEN ERN AREAS AS VORT MOVES THRU.  THIS COULD
LEAD TO SOME OF THE STORMS BECOMING SVR AROUND MIDDAY ROUGHLY ERN
1/2 OF AREA.  UNFORTUNATELY THE FRONT WILL HANG UP JUST TO THE S
LATER TONIGHT KEEPING WX UNSETTLED THROUGH THE MIDDLE PART OF THE
WEEK.  BOTH GFS AND NAM DEVELOP A PLAINS LOW TOMORROW AND TRACK IT
TO THE NE ON WED.  NAM SOL SEEMS A LITTLE OVER AMPLIFIED ALOFT WITH
RESULTANT SFC LOW TRACK ACROSS NRN LOWER MI.  GFS SOL SEEMS A LITTLE
MORE REASONABLE WITH LESS SFC DEVELOPMENT AND A MORE SLY TRACK AND
THUS WILL BE FOLLOWED TDA.  SO...SHOULD BE MAINLY DRY TONIGHT BUT
EXPECT MORE STORMS TUE...AND TUE NIGHT INTO WED AS BAROCLINIC ZONE
LIFTS BACK TO THE N AS SFC LOW APPROACHES.  WL TRY FOR LIKELY
WORDING ALL AREAS TUE NIGHT WITH HIGH CHC POPS WED.

TEMPS COULD BE A LITTLE TRICKY TODAY DEPENDING ON HOW MANY CLOUDS
THERE ARE.  GUID SUGGESTS MOST OF AREA SHOULD SEE 80 DEGS AGAIN
TODAY AND THIS SEEMS TO BE A GOOD STARTING POINT.  COOLER OBVIOUSLY
IN NE OH AND NW PA WHERE THERE SHOULD BE MORE CLOUDS AND PRECIP.
GUID LATER PDS REASONABLE.

&&

.LONG TERM (WED NIGHT THRU SUN)...
NOT MUCH CHG FM YDA TO TDA IN MDLS WITH BASICALLY WARM BUT UNSETTLED
CONDS THRU MID WEEK FOLLOWED BY BUILDING HGTS LATE WEEK AND INTO
THE WEEKEND.  WILL NEED TO BRING BACK CHC POPS FOR TUESDAY NIGHT AS
THE SHORT WAVE RDG BGND TO SHIFT EAST AS AN UPPER LOW MOVES INTO THE
WRN GRTLKS.  NAM/GFS DIFFER ON SFC LOW POSITION WITH THE NAM TAKING
THE SFC LOW ACRS THE WRN LAKES WHILE THE GFS TAKES IT OVER NRN OH
AND LERI.  ALSO THE GFS REMAINS MORE MOIST.  WL CONT TO FOLLOW NAM
TRENDS WED AND ALLOW FOR SOME BREAKS IN THE CLOUDS IN THE GRAPHICS
BUT FCST SHOULD READ MC. WILL ALSO GO WITH SCT SHWRS/TSTMS IN
WORDING VC CHC.  IN THE WAKE OF THIS SYSTEM THURSDAY/FRIDAY...THE
UPPR RDG IN DVLPG IN THE MIDWEST BGNS TO REACH INTO THE AREA WHICH
WILL DRY OUT THE AREA AND BEGIN THE MID SUMMER HEAT WAVE.
