Afternoon thunderstorms were mainly of the garden variety across south central Kentucky. However a few of the stronger storms did produce some sub-severe hail, and one storm intensified enough to produce golf ball sized hail.

The episode as NWS LMK wrote it up.

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 Jun 30, 6:35 PM CST, 1 hour 31 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE LOUISVILLE KY 835 PM EDT TUE JUN 30 2009 .UPDATE (REST OF TONIGHT)... UPDATED FORECAST MAINLY THROUGH 06Z. ADDED ISOLATED THUNDERSTORMS ACROSS SOUTHWEST PORTIONS OF THE FORECAST AREA WITH ISOLATED SHOWERS ACROSS THE NORTHEAST AREAS. THE SOUTHWEST HAS BECOME MILDLY UNSTABLE AND SOME MID LEVEL REFLECTIVITY RETURNS WERE BEGINNING TO SHOW UP ON RADAR AS AN 850MB FRONT APPROACHES THE AREA. THE DEW POINT AT BWG INCREASED AROUND 3 DEGREES OVER THE LAST HOUR. CAN NOT RULE OUT A STRAY STORM SO DECIDED TO UPDATE GIVEN RADAR AND SURFACE OBS TRENDS. EXPECT MOST OF THIS ACTIVITY WILL COME TO AN END BY 06Z AS THE MID LEVEL WAVE PASSES THE AREA AND SOME SUBSIDENCE SETS INTO THE AREA FOR THE REST OF THE NIGHT. ALSO ADJUSTED MINIMUM TEMPERATURES SLIGHTLY ALONG WITH DEW POINTS AND RELATIVE HUMIDY. .SHORT TERM (TONIGHT AND TOMORROW)... THE FORECAST FOR TONIGHT AND TOMORROW IS A BIT OF A CHALLENGE. A SHORTWAVE WILL ROTATE AROUND THE BACK SIDE OF THE LOW THIS EVENING AND WITH IT A BOUNDARY WILL CROSS THE FORECAST AREA. THE MAIN CHALLENGE FOR THIS EVENING WILL BE PRECIPITATION CHANCES. MODELS INDICATE THE POSSIBILITY FOR PRECIPITATION TONIGHT ACROSS THE TENNESSEE/KENTUCKY BORDER AS THE BOUNDARY TRAVERSES THIS AREA. WITH DRY MID LEVEL AIR AND WEAK FORCING WILL LEAVE THE OVERNIGHT HOURS DRY. HOWEVER...AN ISOLATED SHOWER OR THUNDERSTORM OVER FAR SOUTH CENTRAL KENTUCKY CANNOT BE RULED OUT. TOMORROW WILL BE MUCH THE SAME AS TODAY THOUGH THE UPPER LEVEL LOW WILL RETROGRADE TO THE SOUTHWEST SLIGHTLY. THIS WILL BRING THE CHANCE FOR SHOWERS AND THUNDERSTORMS TO MORE OF THE FORECAST AREA TOMORROW AFTERNOON. THINK THAT COVERAGE HOWEVER WILL STILL BE ISOLATED TO SCATTERED. TEMPERATURES WILL BE HIGHLY DEPENDENT ON SHOWER/THUNDERSTORM COVERAGE. WENT A DEGREE OR TWO HIGHER THAN GUIDANCE OVER THE NORTHEAST TONIGHT DUE TO CLOUD COVER. LOWS WILL GENERALLY BE IN THE LOWER 60S. HIGHS TOMORROW WILL RANGE FROM THE UPPER 70S TO LOWER 80S. .LONG TERM (WEDNESDAY NIGHT THROUGH TUESDAY)... WEDNESDAY NIGHT-FRIDAY NIGHT... A SPLIT FLOW PATTERN WILL DOMINATE OUR WEATHER THROUGH THE REST OF THE WORK WEEK...WHERE THE UPPER LOW OVER THE GREAT LAKES WILL FINALLY MOVE EASTWARD AND A SLIGHTLY WEAKENING WRN CONUS RIDGE WILL GIVE US A FLATTENED NW FLOW. WILL HOLD ONTO A FEW RAIN SHOWERS OVER OUR NERN CWA WED NIGHT UNTIL MIDNIGHT FOR RESIDUAL DIURNAL POPS. BUT THE UPPER LOW SHOULD BE SCOOTING EASTWARD AND LEAVE US WITH CLEARING CONDITIONS TOWARDS THRS MORNING. BECAUSE OF THE SPLIT FLOW...SYSTEMS WILL COME CLOSE TO OUR CWA THROUGH FRIDAY...BUT WILL NOT IMPACT US TOO MUCH. HOWEVER...HAVE INSERTED SLT CHC POPS THRS NIGHT AND FRI NIGHT ACROSS OUR SWRN CWA AS WARM-FRONTAL...OVER-RUNNING PRECIP MAY SKIRT OUR SWRN CWA FROM A SFC LOW PRESSURE CENTER DEVELOPING OVER THE SRN PLAINS. THE NAM AND GFS SHOW THIS PRECIP AND IT MATCHES WITH SURROUNDING WFOS. TEMPS SHOULD BE ABOUT 5 DEGREES BELOW NORMAL...WITH LOWER DEWPOINTS AS WELL. SHOULD BE MOSTLY PLEASANT DAYS TEMPERATURE-WISE FOR EARLY JULY. INDEPENDENCE DAY-SUNDAY NIGHT... FOR THE WEEKEND...THE OPERATIONAL GFS AND EURO...AS WELL AS THE GFS ENSEMBLES INDICATE THAT THE SFC LOW OVER THE PLAINS WILL PUSH ITS WARM FRONTAL BOUNDARY TOWARDS OUR CWA...LAYING OUT SOMEWHERE ACROSS OUR SRN CWA OR JUST SOUTH. BECAUSE OF THIS...HAVE INCREASED CHC POPS...BACKED BY ENSEMBLE MOS GUIDANCE...SATURDAY AND SUNDAY. NOT CONFIDENT ON THE BEST TIMING OF PRECIP...BUT GIVEN THE LOCATION OF THE BOUNDARY...THINK OUR SRN CWA WOULD HAVE THE BEST CHC OF PRECIP OVER THE WEEKEND. STAY TUNED FOR A MORE FINE-TUNED HOLIDAY FORECAST AS MODELS COME MORE IN LINE WITH EACH OTHER. BY SUNDAY...HIGH PRESSURE ACROSS THE UPPER MS VALLEY REGION WILL START TO SLIDE SE TOWARDS THE CWA...PUSHING THE FRONTAL BOUNDARY/LOW PRESSURE OFF TO THE SE. HAVE SLT CHC POPS NW TO CHC POP SE...ALL ENDING BY 00Z MONDAY. TEMPS AGAIN OVER THE WEEKEND SHOULD BE BELOW NORMAL...ESPECIALLY WHEREVER RAIN FALLS. IF THE FRONT SETS UP A LITTLE FURTHER NORTH INTO SRN KY...SOME PLACES MAY SEE A LOT OF RAINFALL. FOR NOW...THAT DOES NOT LOOK LIKE THE SCENARIO. MONDAY-TUESDAY... GOOD AGREEMENT BETWEEN THE OPERATIONAL GFS AND THE EURO SHOW HIGH PRESSURE WILL SLIDE SEWD INTO THE AREA FOR THE START OF THE NEXT WORK WEEK. HOWEVER BOTH MODELS HINT THAT THE HIGH PRESSURE WILL SLIDE EASTWARD VERY LATE IN THIS EXTENDED FORECAST...WHERE STRONG RIDGING AND THUS TYPICAL HOT SUMMER TEMPS WILL BE ON THE WAY && .AVIATION (00Z TAFS)... VFR CONDITIONS ARE EXPECTED FOR THE FORECAST PERIOD. MID LEVEL CLOUDS WILL INVADE THE AREA THIS EVENING WITH CIGS AROUND 5 TO 8 KFT. THESE CLOUDS MAY BREAK UP BRIEFLY AS A MID LEVEL FRONT PASSES THROUGH THE AREA. HOWEVER...EXPECT CLOUD COVER TO REDEVELOP BY MORNING AGAIN AT AROUND 6 KFT. SHOWERS WILL BE POSSIBLE AS UPPER LEVEL TROUGH BACKS INTO THE AREA TO THE SOUTHWEST. ANY SHOWERS THAT DEVELOP FROM MID MORNING TO EARLY AFTERNOON SHOULD STAY CONFINED TO SDF AND LEX AND THESE COULD DEVELOP INTO ISOLATED THUNDERSTORMS IN THE LATE AFTERNOON AND EARLY EVENING. OTHERWISE...EXPECT WESTERLY WINDS AROUND 5 TO 12 KTS. && .LMK WATCHES/WARNINGS/ADVISORIES... KY...NONE. IN...NONE. && UPDATE.......LS SHORT TERM...EES LONG TERM....AL AVIATION.....LS
