NWS Jackson, KY wrote its last area forecast discussion before the first event at Sep 7, 9:32 AM EST, 2 hours 58 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE JACKSON KY 1032 AM EDT MON SEP 7 2009 .SHORT TERM.../THE REST OF TODAY/...UPDATED A SHORT WAVE MOVING THROUGH CENTRAL KENTUCKY IS KICKING OFF NUMEROUS SHOWERS AND THUNDERSTORMS ACROSS THE REGION. UPDATED THE FORECAST PACKAGE THIS MORNING TO RAISE POPS...AND THEN TO TWEAK TEMPS DOWN WHERE RAIN AND CLOUDS WILL BE MOST PERSISTENT. WHILE AT IT ADJUSTED ZONE WORDING FOR TONIGHT TO EMPHASIZE THE BEST CHANCE OF RAIN BEING IN THE EVENING. HAVE ISSUED A COUPLE OF STATEMENTS THIS MORNING FOR SOME LOCALLY HEAVY RAINFALL DUE TO TRAINING. THIS WILL CONTINUE TO BE A THREAT. HWO ADDRESSES THIS CONCERN VERY WELL. THE PREVIOUS SHORT TERM FORECAST DISCUSSION FOLLOWS... /TODAY THROUGH WEDNESDAY/ UPPER LEVEL LOW MEANDERING ACROSS THE OHIO VALLEY WILL BE THE FOCUS OF CONTINUED PERIODS OF SCATTERED CONVECTION THROUGH WEDNESDAY. CURRENTLY...AN INVERTED SURFACE TROUGH REMAINS NOSED FROM WESTERN TENNESSEE TO THE NORTHEAST INTO SOUTHERN INDIANA...WITH THE UPPER LEVEL LOW LOCATED IN SOUTHEAST ILLINOIS. BEST CONVECTIVE CLUSTERS HAVE BEEN DEVELOPING WHERE THESE TWO FEATURES ARE SUPERIMPOSED DURING THE OVERNIGHT. MEANWHILE...AN UPPER LEVEL JET STREAK ROUNDING THE BASE OF THE TROUGH HAS ALLOWED FOR AN ENHANCED AREA OF STEADY RAINS ON THE WESTERN SIDE OF THE APPALACHIANS. ANOTHER MORE WELL-DEFINED SHORT WAVE WILL ROTATE THROUGH THE AREA THIS AFTERNOON. HAVE MAINTAINED 50 POPS ASSOCIATED WITH THIS FEATURE...ALTHOUGH THE THREAT OF ISOLATED TO WIDELY SCATTERED PRECIPITATION WILL LINGER THROUGH THIS MORNING AS WELL. HIGH TEMPERATURES WILL LIKELY STRUGGLE AGAIN...ESPECIALLY IN THE EASTERN HALF OF THE AREA. LIKE THE WRF IDEA HERE...AS IT DID A MUCH BETTER JOB YESTERDAY INDICATING THE SUPPRESSED HIGHS. PRECIPITATION WILL RETURN DIURNALLY FOR TOMORROW AND AGAIN ON WEDNESDAY...WITH GRADUALLY LESS COVERAGE EACH DAY AS THE UPPER LEVEL LOW WEAKENS...ALONG WITH ITS ASSOCIATED TRAVERSING SHORT WAVE TROUGHS. SUSTAINED CLOUD COVER WILL ALSO THIN ACCORDING TO MODEL TIME HEIGHTS...SO HAVE SIDED CLOSER TO THE GFS HIGHS FOR TUESDAY AND WEDNESDAY. .LONG TERM.../WEDNESDAY NIGHT THROUGH SUNDAY/ GENERALLY FEW UPDATED WERE NEEDED TO THE EXTENDED FORECAST THIS MORNING AS THE PREVIOUS FORECAST IS GENERALLY CONSISTENT WITH THE MOST RECENT MODEL RUNS AND THE LATEST TRENDS. THE ONLY CHANGE MADE WAS TO RAISE POPS TO SLIGHT CHANCE IN ALL AREAS THU EVENING AND GO WITH SLIGHT CHANCE ON FRIDAY DUE TO UNCERTAINTY AS TO HOW FAST THE FIRST UPPER LEVEL SYSTEM EXITS. ALONG WITH THIS...OPTED TO RAISE SKY COVER SLIGHTLY THROUGH THAT PERIOD AS WELL. ALSO OF NOTE...THE 0Z ECMWF WAS SLOWER MOVING THE SECOND UPPER LEVEL LOW IN OUR DIRECTION...BUT DUE TO RUN TO RUN AND MODEL TO MODEL VARIABILITY AND THE FACT THAT THE 0Z GFS AND 12Z ECMWF WERE GENERALLY IN GOOD AGREEMENT AT THAT TIME RANGE WITH THE UPPER LEVEL LOW...DID NOT MAKE ANY CHANGES FOR SUN. THE PERTINENT PORTIONS OF THE PREVIOUS EXTENDED DISCUSSION FOLLOW: ACTIVE LONG TERM FORECAST CONTINUES TO LOOK ON TRACK AS TWO H5 LOWS IMPACT EAST KENTUCKY...THE LATTER MUCH STRONGER. EARLY IN THE PERIOD...EXPECT SCATTERED SHOWERS AND A FEW THUNDERSTORMS TO BE POSSIBLE AS WEAK H5 LOW HANGS OVER THE LOWER OHIO VALLEY. WILL CONTINUE TO HAVE POPS TAPER OFF IN THE EARLY EVENINGS ON WEDNESDAY AND THURSDAY EVENINGS. COULD NOT KEEP THESE PERIODS DRY AS UPPER LOW INFLUENCE SHOULD KEEP PRECIPITATION HANGING AROUND. THERE SHOULD BE A BRIEF TRANSITION PERIOD FROM THE FIRST/WEAK H5 LOW TO THE SECOND/MUCH STRONGER TROUGH DIGGING SOUTH ACROSS THE UPPER MIDWEST FROM CANADA ON LATE THURSDAY NIGHT THROUGH FRIDAY AND SATURDAY. DURING THIS PERIOD...SOME BRIEF RIDGING SHOULD BUILD IN...REDUCING CHANCES FOR SHOWERS AND THUNDERSTORMS. AS THE TROUGH STARTS TO SCOOT THIS WAY AND BETTER FLOW/FOCUS FOR FORCING NEARS FROM SAT ON WITH SFC COOL FRONT AND BASE OF TROUGH. AS MENTIONED ABOVE...ECMWF IS PREFERRED AND HAS BEEN FUN TO WATCH THE PAST SEVERAL MODEL RUNS OF THE GFS RUN TOWARD THE ECMWF SOLUTION. HAVE ALWAYS PREFERRED THE SLOWER SOLUTION FOR THIS TYPE OF EVENT AND WILL CONTINUE TO DO SO HERE. AT THIS POINT...IT LOOKS LIKE SURFACE COOL FRONT MAY NOT PASS UNTIL SOMETIME ON SUNDAY NIGHT OR MONDAY OF NEXT WEEK. ALSO...WITH THE STRONG POSITIVE TILT TROUGH NEARING THE REGION...CANNOT RULE OUT SOME PRETTY STRONG STORMS AS PRETTY IMPRESSIVE MID LEVEL FLOW COULD COMPLIMENT ANY INSTABILITY THAT DEVELOPS. WILL JUST THROW THE IDEA OUT THERE FOR NOW AND MONITOR THE TRENDS AS THE WEEK PROGRESSES. AS FAR AS TEMPERATURES ARE CONCERNED...HAVE NOT CHANGED MUCH FROM PREVIOUS FORECASTS. STILL FEEL THAT AROUND 80 TO THE LOWER 80S WILL BE REASONABLE EACH AFTERNOON THROUGH THE WEEK AS PARTLY TO MOSTLY CLOUDY SKIES LIMIT INSOLATION AND H85 TEMPS ARE A LITTLE COOLER THAN YESTERDAYS PROGS. STILL WILL NOT RULE OUT UPPER 70S IN A LOT OF LOCATIONS. A SLIGHT WARM UP COULD BE POSSIBLE TOWARD THE END OF THE WEEK AS SOME CLEARING DEVELOPS IN WEAK/BRIEF RIDGING. && .AVIATION.../12Z TO 12Z/ SCATTERED SHOWERS AND THUNDERSTORMS WILL BE PREVALENT ACROSS THE AREA THROUGH THE DAY TODAY AS AN UPPER LEVEL DISTURBANCE TRACKS ACROSS THE REGION. IFR FOG WILL LIFT OUT OF THE VALLEYS EARLY THIS MORNING...WITH MAINLY VFR CONDITIONS HOLDING THROUGH THE DAY...EXCEPT WHEN A SHOWER OR THUNDERSTORM IS OVERHEAD...WHERE TEMPORARY MVFR/IFR CONDITIONS CAN BE EXPECTED. CONVECTION WILL WANE AT DUSK...WITH MVFR/IFR FOG LIKELY FORMING AFTER 06Z AS CLOUDS THIN ALOFT. && .JKL WATCHES/WARNINGS/ADVISORIES...NONE. && SHORT TERM...GEOGERIAN/RAY LONG TERM....JP AVIATION...GEOGERIAN
