NWS Jackson, KY wrote its last area forecast discussion before the first event at Aug 12, 2:15 PM EST, 1 hour 15 minutes earlier.
AREA FORECAST DISCUSSION...UPDATED NATIONAL WEATHER SERVICE JACKSON KY 315 PM EDT THU AUG 12 2010 .SHORT TERM.../TONIGHT THROUGH SATURDAY/...UPDATED ISOLATED CONVECTION HAS FIRED ACROSS THE AREA WITH HEATING. EXPECT THIS ACTIVITY TO DIE OFF QUICKLY BY EARLY THIS EVENING WITH NO WELL-DEFINED TRIGGER SUSTAINING ANY OF THESE CELLS. THE UPPER LEVEL RIDGE AXIS WILL CONTINUE SHARPENING UP ACROSS THE TENNESSEE AND OHIO VALLEY TOMORROW...KEEPING CONVECTION ISOLATED AT BEST ONCE AGAIN. BY SATURDAY...THE RIDGE WILL BE SUPPRESSED ONCE AGAIN AS A STOUT SHORT WAVE TROUGH MOVES THROUGH THE GREAT LAKES AND SKIMS THE OHIO VALLEY. THIS...COMBINED WITH SLIGHTLY DEEPER MOISTURE JUSTIFIES A BIT BETTER COVERAGE...SO WILL MAINTAIN THE 30 POPS. HEAT CONTINUES TO BE THE MAIN STORY...AND WHILE LOWS WILL BE GETTING A BIT COOLER TONIGHT WITH MOSTLY CLEAR SKIES...EXPECT HIGHS TO SOAR INTO THE MID AND UPPER 90S TOMORROW. DEWPOINTS WILL BE A BIT DRIER TOMORROW...HOWEVER STILL EXPECT THE PEAK INDEX VALUES IN THE 100 TO 105 DEGREE RANGE. HIGHS WILL A HAIR COOLER ON SATURDAY...HOWEVER THE HUMIDITY WILL BE BACK UP AGAIN...KEEPING PEAK HEAT INDEX VALUES IN THE 100 TO 105 DEGREE RANGE ONCE AGAIN. .LONG TERM.../SATURDAY NIGHT THROUGH THURSDAY/...UPDATED THE MODELS BEGIN THE EXTENDED PORTION OF THE FORECAST IN DECENT AGREEMENT WITH A PATTERN CHANGE UNDER WAY...AT LEAST FOR THE NORTHERN HALF OF THE CONTINENT. THEY AGREE WITH A BROAD AREA OF TROUGH CROSSING SOUTHERN CANADA AND MOVING INTO THE UPPER MIDWEST FLATTENING THE RIDGE TO ITS SOUTH. WITH TIME THIS TROUGH EXPANDS TO ENCOMPASS THE GREAT LAKES AND OHIO VALLEY FURTHER SHUNTING THE RIDGE TO THE SOUTH AND WEST. ACCORDINGLY...BY EARLY NEXT WEEK THE TROUGH DOMINATED LONGWAVE PATTERN OVER THE OHIO VALLEY WILL KEEP THE WX ACTIVE. THE LARGEST DIFFERENCE AMONGST THE MODELS IS JUST HOW FAR THIS TROUGH EXTENDS INTO THE SOUTH WITH THE OLD ECMWF HOLDING IT BACK FURTHER THAN THE GFS AND GEM. HAVE GONE WITH MORE OF A CONSENSUS SCENARIO...MOST SIMILAR TO THE GFS...THAT KEEPS THE TROUGH IN CONTROL AND THE WORST OF THE HEAT AT BAY. AMIDST THE TROUGH... VARIOUS WEAK SHORTWAVES WILL PASS THROUGH BUT NOTHING OVERLY STRONG TO REALLY PUSH THE COOLER AIR MASS INTO EAST KENTUCKY. SENSIBLE WEATHER WILL FEATURE A NOTICEABLE COOLING TO THE AIR STARTING SUNDAY AND THEN IMPROVING INTO MONDAY AND TUESDAY AS THE TROUGH AND ITS HEIGHT FALLS COMBINE TO SEND A FRONT INTO THE REGION. THIS FRONT MOVES INTO THE AREA ON SUNDAY AND INCREASES THE CHANCE OF THUNDERSTORMS LATER IN THE DAY. THIS RISK OF STORMS WILL CONTINUE INTO THE NIGHT AND FOR A GOOD PORTION OF THE AREA ON MONDAY AS THE FRONT STALLS AND SETTLES OVER EAST KENTUCKY. THE RISK OF CONVECTION WILL STAY WITH US THROUGH MUCH OF THE WEEK WITH A STRONG DIURNAL TREND APPARENT AS THE INITIAL FRONT DISSIPATES OVERHEAD. WITH TIME THE DRIER AIR MOVING INTO THE CWA WILL WORK TO LOWER THE POTENTIAL FOR STORMS FOR WEDNESDAY AND THURSDAY. HOWEVER CONVECTION CANNOT BE RULED OUT AS WE WILL REMAIN ON THE SOUTHERN FRINGE OF THE DEVELOPING GREAT LAKES SFC HIGH WITH THE REMAINS OF THE FRONT NEARBY TO THE SOUTHEAST. THE GOOD NEWS WILL BE THE COOLEST AIR OF THE MONTH WILL FILTER INTO THE CWA NEXT WEEK AND PROVIDE A MUCH NEEDED RESPITE FROM THIS HEAT. AS FOR TEMPERATURES...HAVE FOLLOWED A BLEND OF THE INHERITED GRIDS AND HPC GUIDANCE THROUGH THE PERIOD WITH JUST MINOR TERRAIN BASED ADJUSTMENTS. AS FOR POPS...ENDED UP CLOSER TO THE MEX NUMBERS RATHER THAN THE WETTER HPC ONES. && .AVIATION.../18Z TO 18Z/ WIDELY SCATTERED CONVECTION WILL THREATEN THE AREA THROUGH DUSK. WITH COVERAGE EXPECTED TO BE LIMITED...HAVE ONLY INCLUDED VCSH AT SME AND LOZ. MVFR OR LOWER FOG WILL BE OBSERVED ONCE AGAIN TONIGHT. GENERALLY FOLLOWED PERSISTENCE COMPARED TO LAST NIGHT...AFFECTING LOCATIONS BETWEEN 06 AND 13Z.
