The episode as NWS LMK wrote it up.
A cold front sweeping across the Great Lakes brought a few severe storms to southern Indiana during the overnight hours of September third and fourth.
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 Sep 4, 2:40 AM EST, 1 hour 52 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE LOUISVILLE KY 340 AM EDT SUN SEP 4 2011 .SHORT TERM (TODAY THROUGH MONDAY)... COMPLICATED SHORT TERM FORECAST PERIOD AS OUR AREA WILL LIE BETWEEN SIGNIFICANT UPPER TROUGH AXIS SWINGING ACROSS THE GREAT LAKES TODAY AND MOISTURE STREAMING NORTHEAST AHEAD OF TROPICAL STORM LEE TO OUR SOUTH. SYNOPTIC COLD FRONT AND MOISTURE ASSOCIATED WITH NORTHERN SYSTEM WILL ENSURE SCT TO NUMEROUS SHOWERS AND TSTMS TODAY ACROSS OUR AREA. MEANWHILE...AMOUNT OF TROPICAL MOISTURE WHICH GETS INGESTED FROM LEE INTO NORTHERN STREAM SYSTEM WILL HAVE A SIGNIFICANT EFFECT ON RAINFALL COVERAGE AND HEAVIER RAINFALL AMOUNTS OVER SOUTHERN AND EASTERN AREAS OF CENTRAL KY TONIGHT INTO MONDAY. IN THE VERY NEAR TERM...SCT TSTMS HAVE BEEN OCCURRING OVER PARTS OF W-CENTRAL KY AND TO THE NORTH AND NORTHEAST OF LOUISVILLE LAST COUPLE HOURS. SOME OF THESE CELLS HAVE PUT OUT SOME IMPRESSIVE OUTFLOW BOUNDARIES...WITH THE KY MESONET STATIONS IN WARREN AND OHIO COUNTIES EARLIER HAVING REPORTED GUSTS TO 51 MPH. NORMALLY THESE CELLS WOULD NOT BE THAT IMPRESSIVE. HOWEVER...00 UTC SOUNDINGS AT OHX AND ILN ARE VERY IMPRESSIVE WITH AN INVERTED-V SOUNDING WITH DRY ADIABATIC LAPSE RATES TO AT LEAST 700 MB AND A DRY BOUNDARY LAYER. THUS...SCT TSTMS HAVE BEEN VERY EFFECTIVE IN THEIR MICROBURST AND CONVECTIVE OUTFLOW PRODUCTION. WE HAVE ISSUED A FEW SVR WARNINGS AND A NUMBER OF SPECIAL WEATHER STATEMENTS FOR THESE CELLS. THE MAJORITY OF CELLS NOW ARE JUST OUTSIDE OUR FORECAST AREA. MODELS SUGGEST THAT THIS ENVIRONMENT WILL CHANGE DURING THE DAY TODAY. WITH MORE CLOUD COVER AND INCREASING LOW-LEVEL MOISTURE... LOW-TO0-MID LEVEL LAPSE RATES OVERALL SHOULD GRADUALLY WEAKEN SOMEWHAT TODAY. THIS IS REFLECTED IN LOWER TOTAL TOTALS INDICES LATER TODAY. HOWEVER...THE ENVIRONMENT WILL STILL BE UNSTABLE AND CONDUCIVE TO NUMEROUS TSTMS. HOWEVER...MICROBURST WIND POTENTIAL SHOULD SUBSIDE SOMEWHAT LATER TODAY...ALTHOUGH STILL CANT RULE OUT ISOLATED SVR STORMS DURING THE DAY TODAY. WHILE MULTIPLE OUTFLOW BOUNDARIES COMPLICATE THE CONVECTIVE AND SURFACE WIND FORECAST TODAY...THE SYNOPTIC COLD FRONT WILL APPROACH THE OH RIVER THIS AFTERNOON AND MOVE THRU CENTRAL KY TONIGHT. HIGH TEMPS THIS AFTERNOON WILL BE TRICKY WITH CLOUDS AND RAINFALL LIMITING THE DIURNAL RISE...AND WILL CONTINUE WITH 80S IN THE GRIDS...CERTAINLY COOLER THAN YESTERDAY...BUT ALSO MORE HUMID TODAY AHEAD OF THE FRONT. WITH K INDEX VALUES IN THE 30S TODAY AND INCREASING ATMOSPHERIC MOISTURE...TSTMS WILL BECOME INCREASINGLY MORE EFFICIENT HEAVY RAINFALL PRODUCERS...WITH LOCALLY HEAVY RAIN EXPECTED. LATE TONIGHT INTO MONDAY AS THE NORTHERN STREAM TROUGH IMPINGES ON OUR AREA AND TRIES TO PHASE SOME TROPICAL SOUTHERN MOISTURE...BOTH THE GFS AND ECMWF SHOW A NICE JET STREAK DEVELOPING OVER THE OH VALLEY AND GREAT LAKES...WITH THE RIGHT ENTRANCE REGION OVER THE TN VALLEY INTO SOUTHERN/EASTERN KY (CERTAINLY MORE LIKE A COOL SEASON SYSTEM). THIS SHOULD ENHANCE FORCING AND COULD LEAD TO PERIODS OF HEAVY RAINFALL OVER THE SOUTHEASTERN HALF OF OUR FCST AREA...IF CURRENT MODEL PROJECTIONS ARE CORRECT. CONVECTIVE-DOMINATED RAINS TODAY WILL TRANSITION MORE TO STRATIFORM-DOMINATED RAINS WITH POSSIBLE EMBEDDED CELLS LATE TONIGHT AND MONDAY. ON MONDAY...THE PRECIP SHIELD SHOULD SLIDE SLOWLY TO THE EAST. THIS WILL ALLOW SRN IND AND NORTH-CENTRAL KY TO DRY OUT...WHILE SHOWERS CONTINUE OVER EASTERN PARTS OF SOUTH-CENTRAL KY. TEMPS WILL BE MUCH COOLER WITH A NE SURFACE WIND...WITH HIGH TEMPS PROBABLY ONLY IN THE UPPER 60S AND LOWER 70S...POTENTIALLY EVEN COOLER IN THE SOUTHEAST IF RAIN AND LOW CLOUDS LINGER LONG ENOUGH. .LONG TERM (MONDAY NIGHT - SATURDAY NIGHT)... MONDAY NIGHT - SATURDAY NIGHT... BY MONDAY NIGHT...SFC FRONTAL TROUGH WILL BE WELL SOUTHEAST OF THE AREA WITH THE UPPER LOW ASSOCIATED WITH TROPICAL STORM LEE REMNANTS PUSHING NORTHWARD ACROSS THE GULF STATES. THIS UPPER LOW WILL SLOWLY MOVE TOWARDS OUR CWA AND MOVE OVERHEAD BY LATE WEDNESDAY. EURO AND GFS STILL IN GOOD AGREEMENT WITH THIS SOLUTION...AND IT APPEARS AS THE NAM IS OUT TO LUNCH AND DOES NOT EVEN BRING LEE UP THIS DIRECTION. WENT WITH THE CONSISTENT EURO/GFS AND KEEP POPS IN ACROSS AT LEAST THE SERN/SRN CWA MONDAY NIGHT-TUESDAY...AND THEN OVERSPREADING MOST OF THE AREA THROUGH THE REST OF THE EXTENDED FORECAST AS LEE IS PROGGED TO REMAIN OVERHEAD THROUGH AT LEAST THE ENTIRE WORK WEEK. BECAUSE OF THIS TEMPERATURES OVER THE CWA THROUGHOUT THE WEEK WILL HIGHLY DEPEND ON CLOUD COVER AND ASSOCIATED PRECIP...BUT HIGHS IN THE 70S AND LOWS IN THE 50S LOOKS REASONABLE. MORE BREAKS IN THE CLOUDS/PRECIP SHOULD BE THE RULE LATER IN THE WEEK AS SHOWERS WITH LEE REMNANTS BECOMES MORE SCATTERED AND LESS WIDESPREAD OVER TIME. SOUTHEASTERN SECTIONS OF CENTRAL KENTUCKY...INVOF LAKE CUMBERLAND... HAVE DESCENDED INTO SEVERE DROUGHT RECENTLY BUT THIS IS THE REGION WITH THE BEST SHOT AT SIGNIFICANT RAINFALL. RIGHT NOW THE BEST CHANCES FOR RAIN IN THE LAKE CUMBERLAND REGION APPEAR TO BE MONDAY THROUGH TUESDAY. OVER THE COURSE OF THE WEEK 2 TO 4 INCHES OF RAIN WILL BE POSSIBLE. NO SEVERE WEATHER IS EXPECTED NEXT WEEK. AS A MATTER OF FACT NOT EVEN MUCH THUNDER IS ANTICIPATED...WITH THE BEST CHANCE OF THUNDER RIGHT NOW LOOKING TO BE ON FRIDAY WITH SLIGHTLY STEEPER MID LEVEL LAPSE RATES. && .AVIATION (06Z TAF ISSUANCE)... A COLD FRONT APPROACHING FROM THE NORTHWEST WILL BRING ABOUT A GOOD CHANCE FOR SHRA/TSRA AFTER ABOUT 15Z TODAY FOR ALL THE TERMINALS. UNTIL THEN HOWEVER...CONVECTION AND ASSOCIATED OUTFLOW BOUNDARIES WILL CONTINUE TO THREATEN THE SDF AND BWG TERMINALS WITH ISOLATED-SCATTERED CELLS OVER THE NEXT SEVERAL HOURS. WILL LIKELY HANDLE THIS WITH VCTS/CB AND AMEND ON THE FLY IF NEEDED. WILL KEEP WINDS VARIABLE GIVEN THE OUTFLOW BOUNDARIES. ANY STORMS WILL BE CAPABLE OF PRODUCING WINDS UP TO 40 KTS OVER THE NEXT COUPLE OF HOURS BEFORE DECOUPLING. BRIEF MVFR CIGS/IFR VSBYS WILL BE POSSIBLE WITH ANY STORM AS WELL. THE COLD FRONT LATER TODAY WILL BRING MORE WIDESPREAD SHRA/TSRA AS IT PASSES THROUGH. FROPA AT SDF LOOKS TO BE BY 18Z...AND AT LEX AND BWG BY 00Z. SOME OF THESE STORMS LATER TODAY WITH THE FRONT COULD BE STRONG TO ISOLATED SEVERE...WITH THE BEST CHC OCCURING AT BWG AND LEX. PRECIP SHOULD END TOWARDS THE END OF THIS TAF PERIOD. WINDS OUTSIDE OF ANY STORMS WILL REMAIN GENERALLY LIGHT AND VARIABLE UNTIL MIXING COMMENCES FROM MID-MORNING ON. SW WINDS WILL INCREASE FROM 5-10 KTS. && .LMK WATCHES/WARNINGS/ADVISORIES...
