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 Jackson, KY wrote its last area forecast discussion before the first event at Jul 4, 10:09 AM EST, 1 hour 38 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE JACKSON KY 1109 AM EDT MON JUL 4 2011 .SHORT TERM.../TODAY/...UPDATED SHOWERS AND THUNDERSTORMS DEVELOPED OVER SOUTH CENTRAL KY THIS MORNING AND MOVED/DEVELOPED EASTWARD INTO THE SOUTHERN PORTION OF THE JKL FORECAST AREA. THE PORTION OF THE FORECAST AREA DOWNSTREAM OF THE CONVECTION HAS BEEN RECEIVING SUN AND DESTABILIZING THIS MORNING. BASED ON TRENDS...IT WOULD APPEAR THE CONVECTION WOULD CONTINUE TO MOVE/DEVELOP EASTWARD TODAY. HAVE INCREASED POPS TO 80 PERCENT SOUTH OF KJKL. TO THE NORTH...LOWERED POPS SLIGHTLY TO 50 PERCENT...WITH PERSISTENT CLOUDS HINDERING DESTABILIZATION DURING THE MORNING. THE PREVIOUS SHORT TERM FORECAST DISCUSSION FOLLOWS... /TODAY THROUGH TUESDAY NIGHT/ A WEAKLY DEFINED QUASI-STATIONARY BOUNDARY REMAINS NEAR OR JUST NORTH OF THE OHIO RIVER EARLY THIS MORNING. THIS BOUNDARY HAS BECOME LESS DISCERNIBLE WITH TIME THANKS TO REPEATED ROUNDS OF CONVECTION. AN OUTFLOW BOUNDARY...ORIGINATING FROM A LARGE COMPLEX OF CONVECTION THAT HAMMERED SOUTHERN IL/IN LATE YESTERDAY AFTERNOON INTO THE EVENING...INITIATED A BROKEN LINE OF CONVECTION ACROSS EASTERN KENTUCKY DURING THE OVERNIGHT HOURS. THE LAST OF THIS ACTIVITY WILL EXIT FAR SOUTHEASTERN KENTUCKY BY 4 AM. THE MODELS HAVE RAMPED UP POPS FOR TODAY AS THE BOUNDARY IS ESCORTED SOUTHWARD AS A MORE DEFINED SHORT WAVE TROUGH MOVES THROUGH THE OHIO VALLEY. AS SUCH...HAVE RAISED POPS UP TO LIKELY...PEAKING IN THE AFTERNOON AS THE SHORT WAVE PASSES OVERHEAD. PRECIPITABLE WATER VALUES WILL BE IN THE 1.8-2.0 INCH RANGE TODAY...SO LOCALLY HEAVY RAINFALL AND THE POTENTIAL FOR AT LEAST MINOR NUISANCE FLOODING OF LOW LYING AREAS CAN NOT BE RULED OUT. THE SHORT WAVE TROUGH WILL EXIT THIS EVENING...WITH CONVECTION DIMINISHING. THE BOUNDARY WILL LIKELY LINGER CLOSE ENOUGH TO BRING ADDITIONAL SCATTERED CONVECTION ON TUESDAY AFTERNOON AND EVENING... ALTHOUGH THE FORCING LOOKS WEAKER...SO HAVE JUST MAINTAINED THE INHERITED 30 POPS FOR MOST LOCATIONS. FOR TEMPERATURES...THE MOS HAS COME IN QUITE A BIT COOLER TODAY...WITH THE NAM KEEPING SOME LOCATIONS IN THE 70S TODAY. THERE IS A LOT OF CLOUD COVER UPSTREAM...HOWEVER WILL LEAN CLOSER TO THE GFS MOS...WITH GENERALLY MID TO UPPER 80S EXPECTED FOR MOST. GENERALLY STAYED A BIT UNDER THE GFS GUIDANCE FOR THE REST OF THE SHORT TERM...AS THE NAM LOOKS A BIT TOO CLOUDY AND COOL. .LONG TERM.../WEDNESDAY THROUGH SUNDAY/ THE ECMWF AND GFS CONTINUE TO DIVERGE FOR THE LATTER HALF OF THE EXTENDED. THE GFS HAS BEEN CONSISTENT WITH BUILDING A RIDGE BACK IN ACROSS THE OHIO AND TENNESSEE VALLEYS...WHILE THE ECMWF HAS BEEN A BIT MORE WAFFLED IN RUN TO RUN CONSISTENCY...KEEPING US MORE UNDER THE INFLUENCE OF BROAD TROUGHING. AS A COMPROMISE...DID INTRODUCE SOME SLIGHT CHANCE POPS IN THE SOUTHERN HALF OF THE AREA FOR SATURDAY AND SUNDAY. THE PREVIOUS LONG TERM FORECAST DISCUSSION FOLLOWS... FORECAST MODELS ARE IN GOOD AGREEMENT THAT A BROAD UPPER LEVEL TROUGH WILL BE IN PLACE OVER THE EASTERN U.S. THROUGH AT LEAST FRIDAY. THEY THEN DIVERGE A BIT OVER THE WEEKEND WITH THE 03/12Z GFS WANTING TO BUILD THE UPPER RIDGE BACK INTO THE AREA QUICKER THAN THE ECMWF. AT THE SURFACE...A COLD FRONT WILL DRIFT SOUTHWARD INTO THE AREA BY WEDNESDAY NIGHT AND THURSDAY BRINGING A RENEWED THREAT FOR SHOWERS AND THUNDERSTORMS. THE FRONT WILL STALL IN THE AREA KEEPING THE THREAT FOR THUNDERSTORMS GOING THROUGH FRIDAY EVENING. WE WILL THEN BANK ON THIS FRONT EITHER WASHING OUT OR SETTLING JUST TO OUR SOUTH OVER THE WEEKEND AND WILL KEEP THE SATURDAY AND SUNDAY FORECAST DRY. HOWEVER...THIS WILL NEED TO BE CHANGED IF FUTURE MODEL RUNS INDICATE SOMETHING SIMILAR TO THE 03/00Z ECMWF AND HANG A PIECE OF THE UPPER TROUGH IN OVER OUR AREA THROUGH THE WEEKEND. TEMPERATURES SHOULD BE RATHER SEASONAL WITH LITTLE AIR MASS CHANGE THROUGH THE PERIOD. WE WILL STAY UNDER THE WARM BIASED GFSX MOS GUIDANCE THROUGHOUT...KEEPING HIGHS GENERALLY IN THE MID TO UPPER 80S AND LOWS IN THE MID TO UPPER 60S. && .AVIATION.../12Z TO 12Z/ FOG LIFTING OUT OF THE VALLEY HAS DROPPED CONDITIONS TO LIFR AT JKL. SHOULD IMPROVE TO VFR AS SOON AS THE SUN CAN WARM THE SFC LAYER ENOUGH TO MIX OUT THE MOISTURE. LOZ/SME ARE ALREADY MVFR AND SHOULD IMPROVE TO VFR QUICKLY. SHRA/TSRA ON THE RADAR ARE PROGGED INTO THE REGION WITHIN ABOUT 5-6 HRS. BUT HAVE BEEN STRUGGLING TO MAINTAIN ANY STRENGTH INTO ERN KY. HAVE VCTS IN TAFS AFTER 21 Z BUT WILL HAVE TO MONITOR THE APPROACHING PCPN TO POSSIBLY MODIFY VSBY TO MVFR IF IT CAN HOLD TOGETHER WITH ENOUGH STRENGTH TO PRODUCE HEAVY RAIN. && .JKL WATCHES/WARNINGS/ADVISORIES...NONE. && SHORT TERM...GEOGERIAN/HAL LONG TERM....GEOGERIAN/ABE AVIATION...DUSTY
