NWS Jackson, KY wrote its last area forecast discussion before the first event at Aug 13, 12:53 PM EST, 1 hour 22 minutes earlier.
AREA FORECAST DISCUSSION...UPDATED NATIONAL WEATHER SERVICE JACKSON KY 153 PM EDT FRI AUG 13 2010 .SHORT TERM.../THE REST OF TODAY/ UPPER LEVEL RIDGE WILL KEEP CONVECTION ISOLATED ONCE AGAIN TODAY. TEMPERATURES ARE RUNNING A COUPLE OF DEGREES WARMER THAN THEY WERE YESTERDAY AT THIS TIME...WITH DEWPOINTS RUNNING NEAR OR SLIGHTLY DRIER THAN YESTERDAY. WILL INCREASE THE HIGHS A BIT...WITH READINGS SIMILAR TO YESTERDAY...GENERALLY MID TO UPPER 90S FOR MOST LOCATIONS. THE PREVIOUS SHORT TERM FORECAST DISCUSSION FOLLOWS... /TODAY THROUGH SUNDAY/ A NEARLY STAGNANT WARM FRONT IN THE VICINITY WILL DOMINATE THE WEATHER THRU THE WEEKEND. EXPECT FLOW FROM THE SOUTH TO MAINTAIN THE HEAT AND HUMIDITY THRU SATURDAY WITH HEAT INDEX NUMBERS CONTINUING TO CLIMB PAST THE CENTURY MARK. THEREFORE THE EXCESSIVE HEAT WARNING WILL BE THE MAJOR WEATHER FACTOR THRU SATURDAY. BY SUNDAY WE WILL SEE THE BEGINNING OF A WX PATTERN CHANGE AS LOW PRESSURE WILL SWEEP ACROSS THE GT LKS AND DRAG A COOL FRONT THRU THE COMMONWEALTH. THE SHRA/TSRA THAT REMAIN ISOLATED TO SCATTERED TODAY AND SATURDAY WILL INCREASE IN COVERAGE AS THE FRONT PROVIDES THE TRIGGER. THE INCREASED COVERAGE OF PCPN WILL HELP TO COOL THE AIR AS THE FRONT BRINGS SLIGHTLY COOLER AND DRIER AIR TO THE REGION TO FINALLY EASE THE HEAT. HIGHS ON SUNDAY WILL ONLY REACH THE UPPER 80S TO AROUND 90 AS HEAT INDEX VALUES WILL ONLY CLIMB INTO THE 90S. .LONG TERM.../SATURDAY NIGHT THROUGH THURSDAY/ 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 AN IMPROVING TREND 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 CONTINUING 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/...UPDATED WIDELY SCATTERED SHOWERS AND THUNDERSTORMS WILL THREATEN THE AREA THE REST OF THIS AFTERNOON...AND MAY CONTINUE OVERNIGHT TONIGHT AND AGAIN TOMORROW AFTERNOON. MVFR FOG WILL ALSO OCCUR ONCE AGAIN...GENERALLY BETWEEN 05 AND 13Z. LIFR FOG OR WORSE WILL BE SEEN IN LOCATIONS THAT SEE REPEATED BOUTS OF SHOWERS AND STORMS. GIVEN THE SCATTERED NATURE OF THE ACTIVITY...WILL CONTINUE WITH VCTS AT THE THREE SITES. && .JKL WATCHES/WARNINGS/ADVISORIES...
