The episode as NWS ILN wrote it up.
An upper level disturbance helped to enhance showers and thunderstorms across central Ohio during the evening of July 8 and into the early morning hours of July 9. Some of these storms became strong to severe with damaging winds and sub severe hail the primary threats. Later in the evening these storms continued to move slowly over the same areas, increasing the threat for heavy rainfall and flash flooding.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE WILMINGTON OH
554 PM EDT MON JUL 8 2013
.SYNOPSIS...
A SERIES OF UPPER LEVEL DISTURBANCES WILL RESULT IN A CONTINUED
CHANCE OF THUNDERSTORMS THROUGH MID WEEK. A COLD FRONT WILL PUSH
THROUGH THE AREA WEDNESDAY NIGHT. BUILDING HIGH PRESSURE IN THE
UPPER MIDWEST BEHIND THE FRONT WILL BRING DRIER CONDITIONS FOR
THE REMAINDER OF THE WEEK.
&&
.NEAR TERM /UNTIL 6 AM TUESDAY MORNING/...
UPDATE HAD SHOWERS AND THUNDERSTORMS OVER NORTHEASTERN CWA AND ITS
ASSOCIATED COLD POOL GRADUALLY GET ENTRAINED TO THE FORECAST THAT
WAS ALREADY RUNNING.
SHOWERS AND THUNDERSTORMS ARE SPARKING AHEAD OF A RAPIDLY
WEAKENING CONVECTIVE COMPLEX MOVING THROUGH NORTHERN INDIANA
THIS AFTERNOON. WHILE THE MAJORITY OF OPERATIONAL MODELS DO NOT
HAVE THIS CONVECTION HANDLED WELL AT THE 12Z RUN...THEY ARE NOTING
A SURFACE LOW TRACKING EAST THROUGH MICHIGAN AND A TRAILING
CONVERGENT BOUNDARY IN NORTHERN OHIO. THIS BOUNDARY WILL BE THE
FOCUS FOR THUNDERSTORM ACTIVITY OVERNIGHT. IN THE AIRMASS WE ARE
IN...ANY OF THESE STORMS COULD PRODUCE LOCALLY HEAVY RAINFALL IN
AN AREA THAT MAY NOT BE ABLE TO HANDLE IT. RAPID RUNOFF POTENTIAL
IN THE AREA OF THE WATCH IS COOINCIDENT WITH THE HIGHEST CHANCE
FOR RAIN AND LOWEST FLASH FLOOD GUIDANCE VALUES.
ERRED INITIALLY BY NOT INCLUDING FRANKLIN COUNTY IN THE WATCH.
UPDATED FORECAST AND WATCH INFORMATION TO INCLUDE THIS AS THE
RIVERS OVER DELAWARE COUNTY ARE RUNNING SOUTH AND FLASH FLOOD
GUIDANCE IN NORTH CENTRAL FRANKLIN COUNTY IS QUITE LOW WITH .5 1
HOUR AMOUNTS AND .75 3 HOUR AMOUNTS.
THERE SHOULD BE A DISTINCT CUTOFF IN THE STEADY/HEAVY RAINS OVER
NORTHERN CWA TONIGHT.
OVERNIGHT LOWS WILL BOTTOM OUT AROUND 70 UNLESS THE RAIN COOLED
AIR PUSHES READINGS INTO THE LOW AND MID 60S WHICH IS A REAL
POSSIBILITY OVERNIGHT.
&&
.SHORT TERM /6 AM TUESDAY MORNING THROUGH WEDNESDAY NIGHT/...
MODELS ARE IN DISAGREEMENT WITH THE EVOLUTION OF THE RAIN FROM
TONIGHT. CANNOT REMOVE A CHANCE FOR THUNDERSTORMS IN AN AIRMASS
THAT HAS BEEN EXTREMELY SUPPORTIVE OF THEM FOR THE PAST WEEK OR
MORE. HEAVY RAIN WILL BE A POSSIBILITY WITH ANY OF THESE
STORMS...AND THE CHANCES WILL REALLY INCREASE LATE WEDNESDAY AND
OVERNIGHT AS A DISTINCT COLD FRONT WITH UPPER LEVEL SUPPORT
CROSSES THE AREA. UNTIL THIS TIME...MORE OF THE SAME IS EXPECTED
AND HIGHS WILL GRADUALLY CREEP UPWARDS A DEGREE OR TWO EACH DAY.
NIGHTTIME LOWS WILL ONLY BE MITIGATED TO BE COOLER FROM STORMS
THAT MAY OR MAY NOT BE PRESENT AT TIMES...AT LEAST TUESDAY NIGHT.
OUTSIDE OF THE STORMS...THE AIRMASS WILL RETAIN HIGH DEWPOINTS AND
LIMIT NIGHTTIME DROPOFFS MUCH BELOW 70 DEGREES.
&&
.LONG TERM /THURSDAY THROUGH MONDAY/...
REGION WILL FIND ITSELF SPLIT BY A CDFNT AT THE BEGINNING OF THE
PERIOD. THE FRONT WILL BE LOCATED NEAR THE OHIO RIVER AT 12Z
THURSDAY. MODELS QUICKLY PUSH THE FRONT INTO THE APPALACHIANS AND
REPLACE IT WITH HIGH PRESSURE. THIS SHOULD MEAN SOME LINGERING
CONVECTION FOR THE MORNING HOURS OF THURSDAY IN THE EXTREME
SOUTH...WITH DRY CONDITIONS FOR THE N. MODELS DROP AN H5 S/W INTO
LAKE ERIE THURSDAY AFTN...BUT RIGHT NOW IT APPEARS THAT THE S/W WILL
PRODUCE JUST SOME AFTN CLOUDS AND NOT ANY AFTN SHOWERS.
HIGH PRESSURE WILL BUILD IN THURSDAY NIGHT AND WILL HOLD CONTROL
INTO SATURDAY NIGHT. THIS SHOULD ALLOW THE REGION TO BEGIN TO DRY
OUT.
RETURN FLOW BY SUNDAY WILL BRING THE RETURN OF SCT CONVECTION FOR
SUNDAY AND MONDAY. WENT WITH LOW CHC POPS FOR NOW.
HIGHS THURSDAY INTO SATURDAY WILL BE A FEW DEGREES EITHER SIDE OF 80
FOR THE REGION. BY SUNDAY AND MONDAY...HIGHS WILL RISE INTO THE
LOWER 80S. LOWS WILL BE IN THE LOWER 60S FOR THE FIRST HALF OF THE
PERIOD...THEN THE MID 60S FOR THE LATER HALF.
&&
.AVIATION /22Z MONDAY THROUGH SATURDAY/...
SHOWERS AND A FEW THUNDERSTORMS WILL BE POSSIBLE AROUND KCMH AND
KLCK THIS AFTERNOON. ADDITIONAL SHOWERS AND A FEW THUNDERSTORMS
WILL APPROACH FROM THE WEST FOR LATER THIS AFTERNOON INTO THE
EARLY EVENING HOURS. ANOTHER DISTURBANCE WILL MOVE THROUGH THE
AREA LATE IN THE OVERNIGHT HOURS INTO THE EARLY DAYTIME HOURS ON
TUESDAY WITH ADDITIONAL SHOWER AND ISOLATED THUNDERSTORM ACTIVITY.
VSBYS MAY BE REDUCED IN SOME OF THE HEAVIER SHOWER ACTIVITY. IN
ADDITION SOME FOG WILL BE POSSIBLE OVERNIGHT AT KLUK AND KILN.
OUTLOOK...SCATTERED THUNDERSTORMS POSSIBLE TUESDAY. GOOD CHANCE OF
THUNDERSTORMS WEDNESDAY AND WEDNESDAY NIGHT.
