The episode as NWS LMK wrote it up.
An ongoing MCS across western IL/eastern MO moved into the lower Ohio Valley during the afternoon hours. Most of the storms associated with this sytem remained sub-severe as they crossed the region. However isolated wind damage did occur in Hart county.
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 Louisville, KY wrote its last area forecast discussion before the first event at Jul 18, 5:18 PM CST, 2 hours 40 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE LOUISVILLE KY 718 PM EDT SUN JUL 18 2010 ...UPDATED AVIATION DISCUSSION... .SHORT TERM (TONIGHT AND MONDAY)... WILL HAVE TO KEEP THIS DISCUSSION ABBREVIATED DUE TO ONGOING WEATHER. CURRENTLY...MCS HAS MADE ITS WAY TO TO THE LOWER OHIO VALLEY WITH SOME REDEVELOPMENT/INTENSIFICATION ALONG ITS NORTHERN END IN EASTERN IL/WESTERN IN. THESE STORMS...SCATTERED TO NUMEROUS IN COVERAGE...WILL MAKE THEIR WAY THROUGH THE CWA THE REST OF THIS AFTERNOON THROUGH THE EVENING HOURS. HAVE GONE WITH LIKELY POPS WITH THIS INITIAL ROUND OF STORMS AND SCATTERED POPS AFTER 2 AM TO ACCOUNT FOR FRONTAL BOUNDARY STILL TO THE NORTHWEST. HAVE GONE WITH THE HI RES HRRR AND 4KM SPC WRF FOR THE REST OF THIS AFTERNOON AND EVENING AS THEY HAVE HAD THE BEST HANDLE OF ONGOING CONVECTION. THEREAFTER...CONFIDENCE IS LOW IN COVERAGE OF SHOWERS AND STORMS. HOWEVER...FELT THAT LOW CHANCE POPS WERE WARRANTED CONSIDERING HOW UNSTABLE THE ENVIRONMENT IS AND EMBEDDED WAVES IN THE FLOW NEARING. COULD GET ADDITIONAL REDEVELOPMENT ALONG FRONT IN INDIANA LATER THIS AFTERNOON IF CONVECTIVE DEBRIS CLEARS OUT ENOUGH AND SOME OF THIS CONVECTION COULD SKIRT OUR NORTHERN COUNTIES. AS FAR AS THE ONGOING STORMS ARE CONCERNED...CURRENT LAPS SOUNDINGS SHOW PLENTY OF INSTABILITY TO WORK WITH AND EXPECT CONTINUED INTENSIFICATION AS THE AFTERNOON PROGRESSES. PWATS AROUND 2 INCHES THROUGH THE COLUMN ARE PILING IN THE AREA SO ANY THUNDERSTORM WILL ONCE AGAIN BE EFFICIENT WITH RAINFALL. SOME AREAS HAVE RECENTLY HAD A LOT OF HEAVY RAIN...SO WILL HAVE TO MONITOR FOR FLASH FLOOD THREAT WITH REPEATED THUNDERSTORMS. ALONG WITH DAMAGING WINDS BEING THE MAIN THREAT...FREEZING LEVELS AND WET BULB ZERO HEIGHTS ARE SIMILAR TO YESTERDAY SO LARGE HAIL WILL ALSO BE A THREAT. THE STORM PREDICTION CENTER DOES HAVE MOST OF THE CWA IN A SLIGHT RISK FOR SEVERE WEATHER. WITH FRONTAL BOUNDARY STALLING OUT JUST NORTH OF THE AREA TOMORROW HAVE ONLY GONE WITH ISOLATED POPS IN THE MORNING...HOWEVER SOLID CHANCE POPS ONCE AGAIN TOMORROW AFTERNOON. BEST COVERAGE SHOULD BE NORTH OF I 64. ONCE AGAIN...CONFIDENCE IS LOW IN THIS FORECAST BASED ON HOW UNPREDICTABLE UPSTREAM CONVECTION IS OVER THE NEXT 12 HOURS. WILL APPROACH POPS IN TERMS OF CHANCE OF OCCURRING RATHER THAN COVERAGE FOR THIS PORTION OF THE FORECAST. HIGH TEMPERATURES THIS AFTERNOON ARE FALLING SHORT OF THE 90 DEGREE MARK SO THE SPS FOR HEAT INDICES WAS ALLOWED TO EXPIRE AT 16Z. HAVE GONE NEAR THE LOWEST GUIDANCE FOR HIGHS TOMORROW IN THE UPPER 80S TO AROUND 90. LOW TEMPERATURES TONIGHT SHOULD BE QUITE MILD WITH THE MERCURY BOTTOMING OUT IN THE 70 TO 75 DEGREE RANGE. .LONG TERM (MONDAY NIGHT - SUNDAY)... EARLY PART OF THE PERIOD SHOULD BE WETTER THAN THE REST...AS REGION WILL BE IN A SOMEWHAT ZONAL PATTERN BETWEEN A BUILDING RIDGE TO OUR SOUTH AND SHORTWAVE TROUGHS PASSING BY TO OUR NORTH. TIMING OF THE SHORTWAVES IS DIFFICULT AT THIS POINT GIVEN THE MESOSCALE NATURE OF THE FLOW. GIVEN THAT THE ATMOSPHERE SHOULD REMAIN ABNORMALLY MOIST...CANNOT RULE OUT STORM ACTIVITY AT ANY TIME...BUT WILL KEEP COVERAGE AT SCATTERED FOR NOW. FOR WEDNESDAY TO FRIDAY...MODELS INDICATE THE CENTER OF RIDGE CLOSE ENOUGH TO LIMIT RAIN CHANCES DOWN TO ISOLATED TO PERHAPS LOW-END SCATTERED AT BEST...DESPITE A FAIRLY MOIST AIRMASS. BEST CHANCES WOULD BE OVER THEN NORTHERN HALF OF THE CWA...FARTHER AWAY FROM THE RIDGE CENTER. THE HUMIDITY WILL MAKE HEAT INDICES RISE TO THE 95-100 DEGREE RANGE. FOR THE NEXT WEEKEND...MODEL GUIDANCE HINT THAT THE RIDGE WILL SHIFTLY SUBTLY SOUTH AS TROUGHING TO THE NORTH TRIES TO DOMINATE AGAIN. THAT COULD SEND US INTO A SIMILAR RAINY PATTERN AS WE ARE IN NOW WITH SHORTWAVES MOVING THROUGH THE FASTER FLOW IN BETWEEN. FOR NOW WILL KEEP RAIN CHANCES ISOLATED...NEAR CLIMATOLOGICAL VALUES...AND WAIT TO SEE IF THE RIDGE WILL BE ABLE TO STAY IN CONTROL OVER THE NEXT COUPLE OF DAYS. DO NOT SEE MUCH RELIEF IN THE HEAT INDEX VALUES EXCEPT FOR THE AREAS WHERE STORMS DEVELOP. && .AVIATION (00Z TAF ISSUANCE)... IT LOOKS AS IF THUNDERSTORMS HAVE ENDED FOR TONIGHT AS THE LATEST IR SATELLITE PICTURES CONTINUE TO INDICATE WARMING TOPS. A FEW SHOWERS WILL MOVE ACROSS SDF AND POSSIBLY LEX TONIGHT WITH BWG REMAINING PRECIPITATION FREE. THE CLOUDS WILL REMAIN WELL ABOVE MINIMUM VFR WITH MOST ABOVE 8K FT. WE WILL MENTION MVFR VSBYS AT BWG AND LEX AFTER 09Z AND WILL ALSO MENTION VCTS AFTER 14Z MONDAY AT ALL LOCATIONS. STORMS WILL BE SCATTERED AROUND THE REGION MONDAY WITH A FRONT DROPPING INTO THE LOWER OHIO VALLEY. && .LMK WATCHES/WARNINGS/ADVISORIES... KY...NONE.
