NWS Jackson, KY wrote its last area forecast discussion before the first event at May 30, 8:35 PM EST, 1 hour 5 minutes earlier.
AREA FORECAST DISCUSSION...CORRECTED NATIONAL WEATHER SERVICE JACKSON KY 935 PM EDT SUN MAY 30 2010 .SHORT TERM.../THE REST OF TONIGHT/...UPDATED NO MAJOR CHANGES PLANNED FOR THE PERIOD AS THE CURRENT FORECAST APPEARS TO HAVE A GOOD HANDLE ON THE SITUATION. OTHER THAN A FEW ISOLATED TSTMS AROUND THE CWA...CONVECTION APPEARS TO BE WINDING DOWN. HAVE KEPT THE 20 POPS THRU THE OVERNIGHT TO ACCOUNT FOR ANY ROGUE POP UPS. STILL EXPECTING SOME PATCHY FOG TO DEVELOP IN AND AROUND THE VALLEYS AGAIN AFTER 05Z...THOUGH NOT AS DENSE OR WIDESPREAD AS PREVIOUS NIGHTS...WHICH SHOULD DISSIPATE SHORTLY AFTER SUNRISE. THE PREVIOUS SHORT TERM FORECAST DISCUSSION FOLLOWS... /TONIGHT THROUGH TUESDAY/ CHANGES ARE NOW BEGINNING TO TAKE PLACE ALOFT OVER THE OHIO AND TENNESSEE VALLEYS AND A PERSISTENCE FORECAST WILL PROBABLY NO LONGER BE A VERY GOOD ONE. THE CLOSED LOW TO OUR SOUTHWEST WILL CONTINUE TO SLOWLY OPEN UP AND SHIFT NORTHEAST ACROSS THE STATE THROUGH TUESDAY. AT THE SURFACE... THE WEAK BOUNDARY NEAR THE OHIO RIVER WILL DISSOLVE TONIGHT LEAVING US VOID OF ANY SIGNIFICANT FEATURES UNTIL A COLD FRONT PASSES ACROSS THE AREA ON TUESDAY. THUNDERSTORM ACTIVITY WILL CONTINUE TO POP UP THIS AFTERNOON IN A WIDELY SCATTERED FASHION. PROGS INDICATE THE POSSIBILITY OF SOME NOCTURNAL CONVECTION TONIGHT AS THE UPPER LOW TO OUR SOUTHWEST DRAWS NEAR. SO... WE WILL CARRY A TSTM MENTION ALL NIGHT LONG BUT KEEP POPS LOW. AN INCREASE IN THUNDERSTORM ACTIVITY TO NUMEROUS COVERAGE IS THEN EXPECTED BY MONDAY AFTERNOON AS THE UPPER LOW PASSES OVERHEAD WITH A SLIGHT DIURNAL MIN IN COVERAGE MONDAY NIGHT. ANOTHER UPTICK IN TSTM COVERAGE IS EXPECTED ON TUESDAY AS THE FRONT SLOWLY TRUDGES THROUGH THE AREA. PROGS INDICATE THE FRONT WILL BE OVER US MIDDAY TUESDAY SO WILL KEEP POPS HIGHEST FOR OUR SOUTHEAST COUNTIES... WHICH SHOULD BE ABLE TO EXPERIENCE A LONGER PERIOD OF DESTABILIZATION BEFORE THE FRONT PASSES THROUGH. NO WIDESPREAD SEVERE WEATHER IS EXPECTED AS CLOUD COVER SHOULD KEEP OUR INSTABILITY IN CHECK EACH DAY. PWATS WILL BE INCREASING WITH TIME THOUGH SO SOME HEAVY RAINERS ARE LIKELY BUT STORM MOTIONS WILL BE INCREASING SO THAT WILL KEEP THE THREAT FOR EXCESSIVE RAINFALL AT ANY ONE LOCATION LOW. THE LOW LEVEL FLOW WILL CONTINUE OUT OF THE SOUTHEAST THROUGH TOMORROW. THIS WILL SUCK UP SOME ATLANTIC MOISTURE TONIGHT RESULTING IN MORE OVERALL CLOUD COVER TONIGHT THAN PREVIOUS NIGHTS... AND PROBABLY LESS VALLEY FOG AS WELL. CONSIDERABLE CLOUD COVER WILL THEN LINGER THROUGH TUESDAY HELPING TO SHRINK OUR DIURNAL RANGES A BIT. STAYED CLOSE TO THE WARMER GFS MOS GUIDANCE. HIGHS ARE EXPECTED TO DROP INTO THE LOWER 80S FOR MOST LOCATIONS WITH LOWS IN THE MID 60S. .LONG TERM.../TUESDAY NIGHT THROUGH SUNDAY/ A WEAKENING COLD FRONT WILL BE EXITING TO THE SE BY TUESDAY EVENING...TAKING PRECIP WITH IT AND ALLOWING FOR DECREASING CLOUDS AS MID/UPPER LEVEL DRYING OCCURS AND THE LOW LEVELS STABILIZE. WARM AIR/MOISTURE ADVECTION WILL RETURN ALREADY ON WEDNESDAY. WILL NOT COMPLETELY RULE OUT SHOWERS...BUT WITHOUT SIGNIFICANT FEATURES AFFECTING THE AREA...WILL USE A POP OF ONLY 10 PERCENT. A MENTIONABLE POP DOES RETURN FOR THURSDAY AS THE NEXT STORM SYSTEM CROSSES THE MIDWEST AND BRINGS ENHANCED WARM AIR/MOISTURE ADVECTION AND AN UPPER AIR PATTERN MORE CONDUCIVE TO PRECIP. THE GFS AND ECMWF HAVE COME INTO A LITTLE BIT CLOSER AGREEMENT FOR THE TIMING OF THE SYSTEM SINCE YESTERDAY. THE GFS IS STILL FASTER THAN THE ECMWF...BUT SOME RUNS OF THE GFS HAVE BEEN A BIT SLOWER WITH THE COLD FRONTAL PASSAGE. MEANWHILE...THE 00Z 5-30 ECMWF IS NOT AS PRONOUNCED WITH A WAVE ALONG THE FRONT AS IT WAS 24 HOURS PRIOR...WHICH ALLOWS IT TO BE FASTER WITH THE PROGRESS OF THE PRECIP ALONG THE FRONT AS COMPARED TO YESTERDAY. WILL USE A COMPROMISE OF THE MODELS TO RESOLVE THE DIFFERENCES. THIS YIELDS A MAX POP ON THURSDAY NIGHT...BUT CHANCE POP STILL LINGERING AT LEAST INTO FRIDAY. FOLLOWING THIS SYSTEM...THERE ARE STILL SIGNIFICANT DISCREPANCIES IN THE MODELS. THE 00Z AND 06Z OPERATIONAL GFS HAD A STRONG SYSTEM MOVING SE ACROSS THE GREAT LAKES DURING THE WEEKEND AND BRINGING A COLD FRONT WITH A MUCH COOLER AIR MASS SOUTH ACROSS THE REGION. THE 00Z GFS ENSEMBLE MEAN WAS MUCH MORE SUBDUED WITH THIS...AND THE ECMWF SHOWS ONLY A VERY WEAK SYSTEM. WILL NOT BUY INTO THE 00Z AND 06Z OPERATIONAL GFS RUNS AT THIS POINT. WILL GO WITH ONLY MODEST COOLING FOLLOWING THE THURSDAY NIGHT/FRIDAY COLD FRONT ALONG WITH PERSISTENT LOW POPS THROUGH THE WEEKEND...AS THE 00Z ECMWF WOULD SUGGEST. && .AVIATION.../00Z TO 24Z/ TSTM ACTIVITY BEGINNING TO DROP OFF BUT AM STILL SEEING ENOUGH INSTABILITY AROUND THE AREA TO KEEP VCTS FOR ALL SITES UNTIL 02Z. THEREAFTER...AM EXPECTING A LULL IN THE DEEP CONVECTION BUT STILL CANNOT RULE OUT A STRAY POP UP SHOWER DURING THE OVERNIGHT HOURS AND HAVE ADDRESSED THIS WITH CB GROUPS FOR NOW. GUIDANCE CONTINUES TO INDICATE SOME PATCHY FOG IN ADDITION TO SOME MVFR CIGS AROUND DAWN TAKING VSBYS DOWN TO MVFR. FOG SHOULD CLEAR OUT BY 12Z AS SHOWER ACTIVITY BEGINS TO PICK UP WITH A DEEP LOW PRESSURE SYSTEM OVER THE GULF STATES LIFTING NORTHEAST INTO OUR AREA. FORECAST SOUNDINGS FROM TAF SITES SHOW ENOUGH INSTABILITY THROUGHOUT THE DAY AND HAVE KEPT THE VCTS THROUGH THE MORNING. WITH DEEP CONVECTION LIKELY BECOMING MORE WIDESPREAD DURING THE AFTERNOON HAVE ALSO DECIDED TO ADD -TSRA AFTER 16Z. && .JKL WATCHES/WARNINGS/ADVISORIES...NONE. && SHORT TERM...ABE/MB LONG TERM....HAL AVIATION...MB
