What was reported inside it

Time	Report	Where	Remark
Aug 13, 9:01 PM EDT	HAIL 0.88	5 W Lodi, OH

Local storm reports filed while the alert was in force, from inside its polygon or its counties.

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

Pittsburgh, PA (KPIT), launched 00:00Z, 1.0 hours before the alert went out and 179 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, Aug 13, 7:37 PM EDT, 1 hour 22 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CLEVELAND OH
737 PM EDT WED AUG 13 2008

.SYNOPSIS...
A WEAK TROUGH WILL DROP SOUTH INTO THE AREA TONIGHT THEN LINGER
OVER THE REGION INTO THURSDAY NIGHT. AN UPPER LEVEL LOW OVER
EASTERN CANAD WILL REMAIN NEARLY STATIONARY FOR THE NEXT FEW DAYS.
HIGH PRESSURE WILL BEGIN BUILDING IN FROM THE WEST ON FRIDAY AND
THEN REMAIN OVER THE AREA INTO THE WEEKEND.

&&

.NEAR TERM /THROUGH THURSDAY/...
TROUGH JUST NORTH OF LAKE ERIE WILL DROP SOUTH INTO THE AREA
TONIGHT. A FEW THUNDERSTORMS NEAR THIS TROUGH OVER SOUTHERN
ONTARIO THIS AFTERNOON. THERE IS POSSIBILITY OF SOME OF THESE
STORMS MOVING SE INTO THE AREA THIS EVENING PRIMARILY EASTERN
AREAS. BELIEVE MAIN THREAT WOULD BE THIS EVENING DIMINISHING WITH
LOSS OF DAYTIME HEATING. SO WILL CONTINUE WITH CHANCE POPS
NORTHERN AREAS EARLY TONIGHT WITH SLIGHT CHANCE ELSEWHERE.

&&

.SHORT TERM /THURSDAY NIGHT THROUGH SATURDAY NIGHT/...
TROUGH LINGERS OVER THE AREA THURSDAY AND THURSDAY NIGHT. UPPER
LEVEL LOW OVER SWRN QUEBEC AND SERN ONTARIO AREA WILL HAVE A
COUPLE S/W ROTATING AROUND IT. THIS ALONG WITH DAYTIME HEATING
WILL CAUSE SOME SCATTERED SHOWERS OR THUNDERSTORMS WHICH SHOULD
THEN COULD LINGER INTO THURSDAY NIGHT. SURFACE TROUGH WEAKENS AND
UPPER LEVEL S/W MOVES EAST EARLY ON FRIDAY. HOWEVER UPPER LEVEL
LOW STILL CLOSE TO REGION AND 8H TEMPS DROP TO AROUND 8-10C
FRIDAY. THERE SHOULD BE ENOUGH INSTABILITY WITH THESE FEATURES FOR
A CHANCE OF THUNDERSTORMS PRIMARILY OVER EASTERN AREAS. THEN HIGH
PRESSURE START TO BUILD IN FROM THE EAST LATER FRIDAY AND SHOULD
PROVIDE FAIR WEATHER FRIDAY NIGHT INTO SATURDAY NIGHT.

&&

.LONG TERM /SUNDAY THROUGH WEDNESDAY/...
EXTENDED PORTION OF THE FORECAST SHOULD START OFF QUIET WITH HIGH
PRESSURE IN CONTROL AT THE SURFACE. EVENTUALLY THE RIDGE WILL SLIDE
EAST AND ALLOW FOR WARM ADVECTION/AFTERNOON SHOWERS AND
THUNDERSTORMS TO DEVELOP ON MONDAY BUT TEMPS SHOULD STILL BE AROUND
NORMAL FOR THIS TIME OF YEAR. A COLD FRONT WILL DROP THROUGH THE
LOWER GREAT LAKES REGION BY MID WEEK BUT BOTH THE GFS AND THE EURO
SHOW THIS FRONTAL PASSAGE EVOLVING MORE SLOWLY THAN THEY DID
YESTERDAY. KEPT POPS IN PLACE THROUGH TUESDAY AND INTO WEDNESDAY TO
ACCOUNT FOR THIS SLOWER TIMING...OTHERWISE NO MAJOR CHANGES MADE TO
THE PREVIOUS FORECAST.

&&

.AVIATION /00Z THURSDAY THROUGH MONDAY/...
ISOLATED SHRA/TSRA CONTINUE TO MOVE ACROSS NORTHERN OH THIS
EVENING. TREND HAS BEEN FOR WEAKENING BUT IT WILL BE A COUPLE MORE
HOURS BEFORE ACTIVITY GOES COMPLETELY AWAY. WILL GO WITH TEMPOS
AT KCLE AND KYNG THE NEXT COUPLE OF HOURS WITH VICINITY MENTION AT
A FEW OTHER SITES. ACTIVITY OVER LOWER MI IS EXPECTED TO DISSIPATE
AND SHOULD NOT IMPACT ANY OF THE TAF SITES. VFR CIGS EXPECTED
OVERNIGHT WITH SOME BREAKS POSSIBLE LATER TONIGHT WHICH WILL ALLOW
PATCHY MVFR FOG TO DEVELOP. LATEST MODELS HINTING AT CONTINUING
PRECIP CHANCES FOR THURSDAY AS A WEAK FRONTAL BOUNDARY REMAINS
ACROSS THE AREA. WILL GO WITH TEMPO MENTION ALL SITES DURING THE
AFTERNOON. HOPEFULLY WILL BE ABLE TO PINPOINT THIS ACTIVITY A
LITTLE BETTER WITH LATER PACKAGES.

OUTLOOK...ONCE THE COLD FRONT SLIDES THROUGH CENTRAL OHIO LATE
THURSDAY...LOOKS LIKE HIGH PRESSURE WILL SETTLE OVERHEAD THROUGH
MOST OF THE WEEKEND WITH VFR CONDITIONS EXPECTED. POSSIBLE
DISTURBANCE ON MONDAY WHICH COULD BRING NON-VFR CONDITIONS BUT ITS
STILL A LONG WAY OUT.

&&

.MARINE...
ONSHORE FLOW WILL TURN TO THE SOUTH TONIGHT.  WINDS TURN TO THE NNE
THURSDAY...BUT THINK CONDITIONS WILL REMAIN BELOW SCA CRITERIA.  BUT
CONDITIONS WILL BECOME CHOPPY...ESPECIALLY FOR BOATERS ON THE WEST
END OF LAKE ERIE.

SURFACE HIGH BUILDS MOVES ACROSS THE LAKES OVER THE WEEKEND.  NE
FLOW DEVELOPS...BUT THINK WINDS SHOULD BE LIGHT.
