NWS Jackson, KY wrote its last area forecast discussion before the first event at Aug 4, 3:25 PM EST, 1 hour earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE JACKSON KY 425 PM EDT MON AUG 4 2003 19Z SFC ANALYSIS SHOWS A WASHED OUT FRONT SPREAD THROUGH THE OHIO VALLEY JUST NORTH OF THE OHIO RIVER. SHOWERS AND THUNDERSTORMS ARE BLOWING UP OVER CENTRAL AND NORTHERN KENTUCKY MOVING INTO OUR CWA. HAIL IS A PRIMARY CONCERN WITH THESE STORMS DUE TO THE COOL MID LEVEL TEMPERATURES...BUT FLASH FLOODING WILL ALSO BE A WORRY. MUCH OF EAST KENTUCKY IS ALREADY SATURATED FROM THE RAINS OF THE PAST TWO DAYS. THE MODELS ARE IN EXCELLENT AGREEMENT ALOFT WITH THE DEEP CLOSED LOW SPINNING OUT OF THE OHIO VALLEY INTO NORTHEAST CANADA BY WEDNESDAY EVENING. LATER IN THE PERIOD...ACCORDING TO THE GFS AND OTHER MEDIUM RANGE MODELS...THE WHOLE PATTERN RETROGRADES WITH ANOTHER CLOSED LOW LOOKING TO DROP INTO THE OHIO VALLEY FOR THE WEEKEND. AS WITH THE PAST FEW DAYS...THE SHORTWAVE DETAILS WILL BE CRITICAL TO THE ACTUAL WEATHER RESULT AND ARE NATURALLY NOT IN AS GOOD AGREEMENT. THE MAIN VORT IS SPINNING THROUGH THE AREA CURRENTLY WITH A NODE EXPECTED TO BRUSH BY AFTER MIDNIGHT. THEN WE SEE A LULL IN UPPER LEVEL SUPPORT WITH THE TROUGH LIFTING OUT BEFORE ANOTHER STRONG WAVE IS PROGGED TO DROP IN WEDNESDAY NIGHT. THE GFS SEEMS A BIT OVERDONE WITH THE VORT THAT IT DROPS INTO THE WESTERN TENNESSEE VALLEY ON THURSDAY. THE BULK OF THE ENERGY THEN STAYS TO OUR SOUTH AFTER THIS BEFORE THE NEXT SERIES OF WAVES DIVE IN TO CARVE OUT THE WEEKEND/S UPPER LOW. SENSIBLE WEATHER WILL FEATURE AN ACTIVE EVENING WITH SHOWERS AND MARGINALLY SEVERE THUNDERSTORMS. GENERALLY SMALL HAIL AND FLOODING WHEREVER THE STORMS TRAIN WILL BE THE MAIN CONCERN WITH THESE. EXPECT THESE STORMS TO DIE OUT LATER THIS EVENING BUT ADDITIONAL ONES WILL BE POSSIBLE AFTER MIDNIGHT CONTINUING THE FLOOD THREAT AS PWS ARE NEAR 1.5 INCHES AND THE STORMS WILL BE SLOW MOVING AND PRONE TO TRAINING. AS A RESULT HAVE ISSUED A FLOOD WATCH FOR THE ENTIRE AREA RUNNING THROUGH 8 AM EDT WITH THE MAIN CONCERN THIS EVENING. AFTER TONIGHT WILL GO WITH A MORE DIURNAL TREND TO THE POPS THROUGH THE WEEKEND...PERHAPS SPIKING MORE ON WEDNESDAY. TEMPS WILL BE ON THE COOL SIDE OF NORMAL UNDER THE PERSISTENT TROUGH. MOS TEMPS ARE SIMILAR THROUGHOUT THE PERIOD FOR LOWS...WILL NOT DEVIATE FAR IN THIS PERSISTENT PATTERN. AS FOR MAXES...PREFER THE MAV NUMBERS FOR HIGHS TUESDAY VERSES THE TOO COOL FWC AND MET. THE NUMBERS ARE BETTER FOR WEDNESDAY HIGHS. AS FOR POPS...SPLIT THE DIFFERENCE TONIGHT AND TUESDAY...MAV TOO HIGH TUESDAY NIGHT. AS FOR THE GFE GRIDS AND IFPS...PERFORMED MY USUAL INITIALIZATION OF TEMPS...DEWPOINTS...AND WINDS FOR THE FIRST 60 HOURS FROM THE MESOETA. GENERALLY HAD TO ADJUST HIGHS UP FOR TUESDAY ALSO MASSAGED THE GRIDS FOR OUR CCF POINTS. LITTLE CHANGES TO THE REST THROUGH FRIDAY. BROUGHT UP SKY AND POPS FOR SATURDAY AND SUNDAY AS THE SFC PATTERN RETROGRADES. ALSO CHANGED TONIGHT/S SKY AND POPS TO FOCUS MORE ON EARLIER ACTIVITY. PRELIMINARY CCF NUMBERS: LOZ 064/083 064/084 062 643 JKL 065/082 065/083 065 643 .JKL...FLOOD WATCH FOR MOST OF EAST KENTUCKY THROUGH 8 AM EDT.
