The episode as NWS ILN wrote it up.
Disturbances moving along a stalled frontal boundary interacted with an unstable air mass to produce numerous showers and thunderstorms across the area. Some of these storms organized and became severe. The main threats from these storms were damaging winds and localized flooding.
The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Wilmington, OH wrote its last area forecast discussion before the first event at Aug 31, 2:44 PM EST, 1 hour 13 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE WILMINGTON OH 344 PM EDT SAT AUG 31 2013 .SYNOPSIS... SUBTLE DISTURBANCES MOVING ACROSS A WEAK FRONTAL BOUNDARY WILL COMBINE WITH A WARM AND HUMID AIRMASS TO PRODUCE PERIODS OF SHOWERS AND THUNDERSTORMS THROUGH SUNDAY. A COLD FRONT APPROACHING THE AREA SUNDAY NIGHT INTO EARLY MONDAY MAY BRING ADDITIONAL CHANCES FOR PRECIPITATION. BEHIND THE FRONT MONDAY...COOLER AND DRIER AIR WILL MOVE INTO THE REGION. && .NEAR TERM /UNTIL 6 AM SUNDAY MORNING/... A FRONTAL BOUNDARY LAYING NEARLY STATIONARY EXTENDS FROM CHICAGO SOUTHEASTWARD ACROSS THE CENTRAL PORTIONS OF THE FORECAST AREA. SOUTH OF THIS BOUNDARY...TEMPERATURES ARE CLIMBING NEAR 90. NORTH OF THIS BOUNDARY...TEMPERATURES ARE IN THE LOWER TO MIDDLE 80S. ALONG THIS BOUNDARY...A CLUSTER OF SHOWERS AND THUNDERSTORMS HAS BEEN PERSISTENTLY MOVING SOUTHEASTWARD AND IS NOW MOVING INTO THE ILN FORECAST AREA. THIS CLUSTER IS EXPECTED TO CONTINUE SOUTHEASTWARD WITH A TENDENCY TO BUILD SOUTHWARD WITH TIME...INTO THE BETTER INSTABILITY. FLOW IS VERY WEAK...SO ANY SEVERE WEATHER WILL LIKELY BE ISOLATED. THE MAIN AREA OF CONCERN FOR ANY SEVERE WEATHER WILL BE ACROSS THE SOUTHWEST WHERE THE GREATEST INSTABILITY IS LOCATED. THESE SEVERE THREATS WILL BE DOWNBURST WINDS AND LARGE HAIL. HEAVY RAINFALL COULD BE A THREAT FROM THIS AFTERNOON THROUGH TONIGHT DUE TO THE SLOW MOVING NATURE OF THESE STORMS AND PWAT VALUES INCREASING FROM 1.5 TO 2 INCHES THIS AFTERNOON INTO TONIGHT. HEAT INDICES ARE ALSO IN THE MIDDLE TO UPPER 90S ACROSS THE SOUTHWEST THIS AFTERNOON. WILL HIGHLIGHT THESE THREATS IN THE HWO. UPSTREAM...ADDITIONAL SHOWERS AND THUNDERSTORMS CLUSTERS OVER NORTHERN ILLINOIS ASSOCIATED WITH A WEAK DISTURBANCE INTERACTING WITH THE FRONTAL BOUNDARY WILL APPROACH OUR AREA LATER THIS EVENING. WITH PWAT VALUES NEARLY 2 INCHES ADVECTING NORTH AND EASTWARD THIS EVENING AHEAD OF THESE CLUSTERS...CONVECTION SHOULD HOLD TOGETHER INTO THE LATE EVENING HOURS AND POSSIBLY OVERNIGHT AS THE DISTURBANCE CROSSES THE ILN FORECAST AREA. THEREFORE AM KEEPING CHANCE POPS THROUGHOUT THE MAJORITY OF THE NIGHTTIME PERIOD. WITH PLENTY OF CLOUD COVER EXPECTED AND A WARM AIRMASS IN PLACE...LOWS WILL NOT DROP BELOW 70 IN MOST LOCATIONS. && .SHORT TERM /6 AM SUNDAY MORNING THROUGH MONDAY NIGHT/... ONGOING CONVECTION ASSOCIATED WITH THE PREVIOUSLY MENTIONED WEAK DISTURBANCE IS EXPECTED TO BE EAST OF OUR AREA BY SUNRISE SUNDAY. THE HIGH PWAT FIELD IS EXPECTED TO LINGER ACROSS AT LEAST THE EASTERN PORTIONS OF THE FORECAST AREA INTO THE DAYTIME WHILE A SHORTWAVE DROPS SOUTHEASTWARD ACROSS THE GREAT LAKES. THE COMBINATION OF DAYTIME INSTABILITY...A FRONTAL BOUNDARY IN THE VICINITY...AND THE INCREASING SHORTWAVE ENERGY ACROSS OUR AREA SHOULD PRODUCE SHOWERS AND THUNDERSTORMS SUNDAY AFTERNOON AND EVENING....PRIMARILY ACROSS THE SOUTHEASTERN HALF OF THE FORECAST AREA. TEMPERATURES SOUTH OF THE FRONTAL BOUNDARY WILL RISE INTO THE UPPER 80S TO LOWER 90S WHILE RISING INTO THE MIDDLE 80S NORTH OF THE BOUNDARY. DEWPOINTS IN THE LOWER 70S ACROSS THE SOUTHWEST COMBINING WITH TEMPERATURES IN THE UPPER 80S TO LOWER 90S...EXPECT HEAT INDICES TO ONCE AGAIN RISE INTO THE MIDDLE TO UPPER 90S. ALTHOUGH WIND SHEAR WILL REMAIN WEAK SUNDAY AFTERNOON...STRONGER UPDRAFTS COULD PRODUCE LARGE HAIL AND DAMAGING WINDS. WILL HIGHLIGHT THESE SEVERE THREATS AS WELL AS THE HEAT IN THE HWO. LOW PRESSURE WILL PASS NORTH OF OUR AREA ALONG WITH THE UPPER TROUGH SUNDAY EVENING. THIS WILL BRING A COLD FRONT ACROSS OUR AREA STARTING SUNDAY NIGHT. A SECONDARY SPIKE OF PWAT VALUES ARE BEING INDICATED IN THE MODELS SUNDAY NIGHT JUST AHEAD OF THE FRONT WHERE PRE-FRONTAL FORCING IS OCCURRING. HOWEVER...THE LOSS OF DAYTIME HEATING WILL PROBABLY KEEP WIDESPREAD CONVECTION FROM OCCURRING. THEREFORE AM FORECASTING IN THE 40 POP RANGE FOR SUNDAY NIGHT INTO THE FIRST PORTIONS OF THE DAY MONDAY AS THE FRONT MOVES ACROSS THE AREA. BEHIND THE FRONT...COOLER AND DRIER AIR WILL BEGIN TO MAKE ITS WAY INTO OUR AREA. THIS COOLER AIRMASS WILL AFFECT THE NORTHWESTERN ZONES FIRST MONDAY MORNING...SPREADING SOUTHEASTWARD THROUGH THE DAY MONDAY. EXPECT HIGHS TO RANGE FROM NEAR 80 ACROSS THE NORTHERN ZONES TO THE MIDDLE 80S ACROSS THE SOUTH. BY MONDAY EVENING NOTABLY COOLER AND DRIER CONDITIONS WILL BE FELT ACROSS ALL ZONES. THE COOLER AND DRIER AIR WILL CONTINUE TO FILTER INTO THE REGION MONDAY NIGHT WITH TEMPERATURES MONDAY NIGHT DROPPING INTO THE 50S ACROSS MOST LOCATIONS. && .LONG TERM /TUESDAY THROUGH SATURDAY/... THE LONGWAVE PATTERN THROUGH THIS PERIOD CONTINUES TO BE STABLE WITH ABOVE AVERAGE AGREEMENT IN VARIOUS DETERMINISTIC RUNS OF ECMWF/GFS/CMC AND THEIR ENSEMBLE MEANS. IT CONTINUES TO BE A FAIRLY AMPLIFIED PATTERN WITH THE LONGWAVE /HOT/ RIDGE IN THE ROCKIES AND A TROUGH IN THE EASTERN CONUS. AN IMPORTANT FEATURE IS A CLOSED LOW OFF THE PAC NW COAST THAT SHOULD KICK INLAND INTO THE NRN ROCKIES LATE IN THE WEEK. THERE IS TIMING/DISCREPANCY ISSUES WITH THIS FEATURE...WHICH HAS EFFECTS ON HOW FAST OR SLOW HEIGHTS RISE ON THE BACKSIDE OF THE ERN CONUS TROUGH. THIS INDUCES SOME UNCERTAINTY ON RAIN CHANCES AND HOW FAST TO WARM THE AREA NEXT WEEKEND. UNTIL THEN...STRONG SHORTWAVE MOVING THROUGH SERN CANADA WILL SERVE TO LOWER HEIGHTS ENOUGH TO ALLOW THE COLD FRONT FROM MONDAY TO EXIT TO THE SOUTHEAST...SETTING UP A DRY/SUNNY/COOL PERIOD FOR TUES/WED/THURS/FRI. TEMPS THIS PERIOD SHOULD RUN SLIGHTLY BELOW NORMAL BUT MORE IMPORTANTLY THE LOW LEVEL MOISTURE FIELD WILL BE BELOW NORMAL AND THUS EXPECT DEW POINTS TO BE LARGELY IN THE 50S...PERHAPS TOUCHING 60 LATER IN THE WEEK...AND IN THE MORNINGS WHEN DEW INITIALLY BURNS OFF. THERE/S A SIGNAL OF A WEAK SHORTWAVE AND FRONTAL PASSAGE IN THE THURS TIMEFRAME - EXPECT THIS TO BE A DRY PASSAGE WITH LITTLE IF ANY SENSIBLE WX IMPACTS. AM SURE MOST MORNINGS WILL HAVE BOUTS OF FOG IN THIS TIMEFRAME. HEADING INTO NEXT WEEKEND...DEPENDING HOW FAST THE PAC NW CLOSED LOW COMES ASHORE WILL TELL HOW FAST TO RISE HEIGHTS DOWNSTREAM OVER THE GREAT LAKES AND BEGIN TO RETURN A WARMER/MORE MOIST AIRMASS. THE 31.12Z GFS SLOWED DOWN THIS FEATURE AND THUS ALLOWED A STRONGER WAVE TO LOWER HEIGHTS AGAIN NEXT WEEKEND WITH A COLD FRONT/RAIN THREAT ON SATURDAY...AND NOT READY TO GO YET ON THAT SIGNAL. SO HAVE MAINTAINED A DRY FORECAST...BUT WITH CAUTION ON THE FRI/SAT PORTION OF THE FORECAST THAT WILL NEED TO BE RESOLVED IN TERMS OF DEGREE OF WARMING AND THREAT OF RAIN. SO MUCH HOT AIR IS BUILT UNDER THE DEEP LAYER RIDGE TO THE WEST...THAT ANY EXTENSION OF THIS INTO THE OHIO VALLEY ON A SHORT TERM BASIS MAY REALLY BOOST TEMPS QUICKLY NEXT WEEKEND. SO HAVE WARMED EACH DAY INCREMENTALLY AFTER WED...NOTING NEXT WEEKEND MAY BE WARMER THAN FCST IF PAC NW CYCLONE IS ON THE QUICKER END OF THE SPECTRUM. && .AVIATION /19Z SATURDAY THROUGH THURSDAY/... THUNDERSTORMS DEVELOPING IN AN UNSTABLE AIRMASS...AIDED BY SHORT WAVE ENERGY ALONG A FRONTAL BOUNDARY...WILL AFFECT TAF SITES. DAY CMH AND LCK APPEAR MOST AT RISK FOR ORGANIZED CONVECTION TODAY SO WENT WITH TEMPO GROUPS CONTAINING MVFR CONDITIONS FOR A COUPLE OF HOURS THIS AFTERNOON. WILL MONITOR WEATHER APPROACHING OTHER SITES CVG LUK AND ILN FOR POSSIBLE SIMILAR CONDITIONS. ONCE CONVECTION WEAKENS OVERNIGHT WITH LOSS OF DAYTIME HEATING...BR MAY FORM AT LUK AND ILN. THUNDERSTORMS WILL BE POSSIBLE AGAIN ON SUNDAY AFTERNOON IN THE SLOWLY EVOLVING WEATHER REGIME. OUTLOOK...THUNDERSTORMS WILL BE POSSIBLE THROUGH MONDAY. && .ILN WATCHES/WARNINGS/ADVISORIES...

SCATTERED SHOWERS AND THUNDERSTORMS ARE EXPECTED THIS AFTERNOON AND THIS EVENING. ALTHOUGH WIDESPREAD SEVERE WEATHER IS NOT EXPECTED...AN ISOLATED SEVERE STORM WITH DAMAGING WINDS AND LARGE HAIL CAN NOT BE RULED OUT GIVEN HIGH INSTABILITY. ALSO...THE ATMOSPHERE WILL BE VERY MOIST...SO LOCALLY HEAVY RAIN WILL OCCUR WITHIN THE STRONGER STORMS. THIS MAY RESULT IN LOCALIZED FLOODING. HIGH TEMPERATURES IN THE UPPER 80S TO THE LOWER 90S COMBINED WITH THE HIGH HUMIDITY WILL PUSH HEAT INDEX VALUES INTO THE MID AND UPPER 90S THIS AFTERNOON. .DAYS TWO THROUGH SEVEN...SUNDAY THROUGH FRIDAY. THUNDERSTORMS ARE EXPECTED TO DEVELOP SUNDAY AFTERNOON. ISOLATED SEVERE STORMS WILL BE POSSIBLE WITH DAMAGING WINDS AND LARGE HAIL BEING THE PRIMARY THREATS. IT WILL REMAIN VERY WARM AND MUGGY ON SUNDAY. HIGHS IN THE UPPER 80S TO THE LOWER 90S...ALONG WITH HIGH HUMIDITY...WILL PUSH HEAT INDEX VALUES INTO THE MID AND UPPER 90S ONCE AGAIN. .SPOTTER INFORMATION STATEMENT...
