What happened
The episode as NWS PAH wrote it up.
A large cluster of thunderstorms sagged southeast into a region of relatively steep low level lapse rates where strong solar heating occurred. Moderately strong instability and ample low level moisture contributed to storm maintenance. A few of the stronger storms produced strong outflow winds. Heavy rain occurred due to the size and speed of the complex.

AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE PADUCAH KY 324 PM CDT MON AUG 10 2009 .DISCUSSION... DEEP MOIST CONVECTION OVER SERN MO INITIALLY FIRED ALONG AN LINGERING WEST TO EAST OUTFLOW BOUNDARY. SFC BASED CAPES OF 3000+ J/KG WERE SEEN THERE EARLIER...AND ALSO OVER SWRN IND/NRN KY NEAR ANOTHER OUTFLOW BOUNDARY AT THE TIME OF THIS WRITING. PWATS CONTINUE TO BE GENERALLY AROUND TWO INCHES ACROSS THE PAH FCST AREA... WHICH CERTAINLY MAKES HEAVY RAINFALL LIKELY UNDER ANY TSTM. WRLY UNIDIRECTIONAL WINDS THROUGH THE COLUMN AND MEDIOCRE MID LEVEL LAPSE RATES WILL CONTINUE TO PUT SOME LIMITATIONS ON SVR POTENTIAL...THOUGH WILL CERTAINLY NOT ELIMINATE IT...ESPECIALLY NORTH OF THE OHIO RIVER. DAMAGING WIND WILL BE THE PRIMARY CONCERN WITH ANY SVR STORMS. POPS WERE LOWERED A BIT OVER MOST OF THE PAH FCST AREA TO REFLECT THE SCT NATURE OF MOST OF THE ACTIVITY THIS AFTN. SHWRS/TSTMS SHOULD LAST A WHILE INTO THE EVE BEFORE TEMPORARILY DISSIPATING OVNGT. A MID LEVEL SHRTWV TROF WILL APPROACH THE REGION ON TUE...AND A COLD FRONT IS EXPECTED TO SWEEP THROUGH MOST OF THE REGION DURING THE DAY...PROVIDING PLENTY OF LOW LEVEL FORCING FOR CONVECTION. NAM WAS THE FAVORITE MODEL HERE...GFS SHOWED AN OVERDONE QPF BULLSEYE. THIS SEEMED TO AFFECT ITS WIND FIELDS. BECAUSE OF MORE EXTENSIVE CLOUDINESS...INSTABILITIES SHOULD BE MORE LIMITED TUE AFTN COMPARED TO TODAY. STILL...WE WILL BE UNDER THE SAME VERY MOIST AIR MASS. SVR WX WILL NOT BE OUT OF THE QUESTION ESPECIALLY IN THE SRN HALF OF THE REGION. PCPN WILL END TUE NIGHT AS THE MID LEVEL FLOW BECOMES NRLY. TOWARD THE WEEKEND...THE MID LEVEL FLOW WILL BECOME ANTICYCLONIC...KICKING IN ANOTHER WARMING TREND. FRIDAY THROUGH SUNDAY...GFS AND ECMWF SHOW AN UPPER LOW SOUTHEAST OF THE PAH FORECAST AREA EARLY FRIDAY...SLIDING SLOWLY NORTH TO NORTHEAST THROUGH THE WEEKEND. GFS IS MORE AGGRESSIVE IN BRINGING PRECIP INTO OUR REGION LATE FRIDAY INTO FRIDAY NIGHT...WHILE THE ECMWF HOLDS OFF PRECIP UNTIL SATURDAY...AND THEN KEEPS IT ONLY ACROSS THE SOUTHEAST HALF OF THE FA. BOTH MODELS KEEP THE AREA DRY SATURDAY NIGHT...THEN THE ECMWF PAINTS JUST A HUNDREDTH ACROSS THE FA ON SUNDAY. FOR NOW ONLY WENT WITH SOME SLIGHT CHANCE POPS WHERE MODELS ARE IN CLOSEST AGREEMENT...WHICH IS ACROSS THE SOUTHEAST HALF OF OUR COUNTIES ON SATURDAY. KEPT THE REST OF THE EXTENDED DRY FOR NOW. FOR TEMPS...LOOKS LIKE WE WILL BE FAIRLY SEASONABLE THROUGH THE EXTENDED WITH LIGHT SOUTHERLY WINDS ACROSS THE REGION. WENT WITHIN A COUPLE OF DEGREES OF LATEST MEX GUIDANCE...WHICH ONLY REQUIRED SOME MINOR TWEAKS. && .AVIATION... ONE BOUNDARY EXTENDING ACROSS SE MO JUST SOUTH OF KCGI AND ACROSS WEST KY SOUTH OF KOWB IS TENDING TO DISSIPATE AS TSRA SLOWLY MOVES EAST FROM SE MO...WHILE NEW SHRA/TSRA FOCUS ALONG ANOTHER W-E ORIENTED BOUNDARY TO THE NORTH OF KEVV. THE BEST CHANCE OF TSRA THIS AFTERNOON WILL BE NEAR THIS BOUNDARY WHICH WILL SLOWLY PUSH SOUTHEASTWARD...WITH CHANCES WILL DECREASE NEAR SUNSET. ATTM HAVE JUST IFR VIS IN KCGI TAF...BUT DEPENDING ON RAINFALL LATER TAFS MAY NEED LOWERED VIS. OTHERWISE THE NEXT CONCERN WILL BE WITH ANY AREAS OF SHRA/TSRA PUSHING EASTWARD INTO THE AREA ON TUESDAY. && .PAH WATCHES/WARNINGS/ADVISORIES... KY...NONE. MO...NONE. IL...NONE. IN...NONE. && SHORT TERM...DB LONG TERM/AVIATION...RST
