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

The local office's own words before this severe thunderstorm warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Cleveland, OH wrote its last area forecast discussion before this severe thunderstorm warning went out at Jul 21, 2:21 AM EDT, 1 hour 7 minutes earlier.

Area forecast discussion, Jul 21, 2:21 AM EDT, 1 hour 7 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CLEVELAND OHIO
221 AM EDT THU JUL 21 2005

.SHORT TERM (TODAY THRU SATURDAY)...
CONVECTIVE COMPLEX SLOWLY TRACKING EAST SOUTHEAST ACROSS THE AREA.
IT SHOULD TAKE A GOOD PORTION OF THE NIGHT TO CLEAR THE AREA OR
DISSIPATE ALL TOGETHER. THIS COMPLEX IS IN RESPONSE TO 500 MB
SHORTWAVE MOVING EAST ACROSS THE AREA AS WELL.

THE PROBLEM FOR THE DAY IS HOW LONG WILL IT TAKE TO CLEAR THIS
PRECIPITATION OUT OF THE AREA.  AS AVIATION FORECASTER MENTIONED
BELOW...BUBBLE HIGH IN THE WAKE OF THIS COMPLEX WILL MAINTAIN ITSELF
THROUGH THE MORNING TO SUPPRESS CONVECTION.  IT APPEARS THOUGH WITH
SWATH OF MOISTURE WE COULD QUICKLY DESTABILIZE IN THE AFTERNOON FROM
DAY TIME HEATING CAUSING ISOLATED CONVECTION TO DEVELOP.  A LIGHT
NORTH WIND WILL DEVELOP OFF LAKE ERIE AND THIS WILL HAVE A
STABILIZING EFFECT ON THE LAKE SHORE AREAS.  SO CONVECTION SHOULD BE
CONFINED TO AREAS AWAY FROM THE LAKE THIS AFTERNOON.  HOWEVER...I
WILL STILL KEEP A MENTION FOR A CHANCE ALONG THE LAKE AS WELL.

TONIGHT WILL SEE ANOTHER ONGOING PROBLEM BRUSH THE AREA.  ANOTHER
SHORTWAVE UP OVER SOUTH DAKOTA WILL MOVE SLOWLY SOUTHEAST TO WESTERN
OHIO. WATER VAPOR IMAGERY AND NAM AND GFS MODELS ALL SHOW THIS
SHORTWAVE OCCURRING AT THE MOMENT WITH A CLUSTER OF CONVECTION
ASSOCIATED WITH IT.  I AM EXPECTING THIS FEATURE TO AFFECT THE
WESTERN AREAS OF THE FORECAST AREA BY FRIDAY MORNING.  WEAK
SHORTWAVES WILL ALSO MOVE ACROSS THE REST OF THE AREA FRIDAY
MORNING...HENCE WILL GIVE AREA A CONTINUED CHANCE FOR SHOWERS AND
THUNDERSTORMS.

HIGH PRESSURE SYSTEM BUILDS SOUTH ACROSS THE AREA BY LATE AFTERNOON
FRIDAY ENDING THREAT OF THUNDERSTORMS SETTING UP FOR A QUIET NIGHT
FRIDAY NIGHT INTO SATURDAY.  STRONG WARM AIR ADVECTION EXPECTED
SATURDAY IN THE WAKE OF THE SURFACE HIGH AND IN ADVANCE OF NEXT
STORM SYSTEM MOVING NORTHEAST INTO THE WESTERN GREAT LAKES. THE
CHANNELLING EFFECT OF THESE TWO SYSTEMS WILL CAUSE TEMPERATURES AND
DEW POINTS TO INCREASE MAKING FOR ANOTHER COUPLE MUGGY DAYS WITH
TEMPERATURES AROUND 90 AND DEW POINTS IN THE LOWER TO MIDDLE 70S.

ONLY REAL MAJOR CHANGE TO THE FORECAST WILL BE THIS MORNING IN
TRYING TO TIME PRECIPITATION AS IT MOVES ACROSS THE AREA.
OTHERWISE...MADE SOME MINOR TWEEKS TO TEMPERATURES TO BRING THEM
DOWN A TAD ON FRIDAY FOR HIGHS. TODAY SHOULD BE QUITE WARM WITH
HIGHS AROUND 90 CENTRAL TO LOWER 90S WEST AND UPPER 80S EAST. LOWS
GENERALLY IN THE 60S TO LOWER 70S EACH DAY.
&&

.LONG TERM (SATURDAY NIGHT THROUGH WEDNESDAY)...
TIMING OF PCPN VERY TOUGH. MODELS GENERALLY AGREE WITH A FRONT FOR
TUE NIGHT. OTHER THAN THAT WITH THE AMS MOIST AND UNSTABLE THERE
WILL BE A THREAT OF PCPN. GUID OK. WITH PLENTY OF WARM TEMPS AT 850
MB WE HAVE TO WATCH HIGHS.
&&

.AVIATION(06Z-06Z)...
NEWLY DVLPD STORMS OVR NW OH/N IND WILL REDEVLOP TO THE SOUTH AND
WEST HOWEVER THE MEAN FLOW WILL DRAG OUT SOME OF THE ACTIVITY
EASTWARD SO WL FCST TEMPO TSRA FOR 2-3 HOURS ALL BUT ERIE EARLY THIS
MORN. MODELS FCST BUBBLE SFC HIGH TO DVLP IN WAKE OF THE STORMS OVR
LWR LAKES AND WL TAKE A CHC AND KEEP TAFS DRY DURING THE DAY THUR. A
LITTLE DAYBREAK FOG AND HZE LIKELY AND THERE IS A CHANCE FOR A
COUPLE OF HOURS OF BKN MVFR CU DEVELOPING DURING THE MORNING BUT
WILL KEEP MVFR CLOUDS SCT AT THIS TIME.
