NWS Jackson, KY wrote its last area forecast discussion before the first event at Aug 2, 1:53 AM EST, 3 hours 12 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE JACKSON KY 253 AM EDT SAT AUG 2 2003 BIGGEST CHALLENGE FOR THIS MORNING/S FCST WAS ONCE AGAIN CHANCES FOR PCPN ASSOCIATED WITH LARGE UPPER LOW PIVOTING ACROSS WESTERN LAKE SUPERIOR. WHILE GFS/ETA ARE IN PRETTY GOOD AGREEMENT ABOUT THE TIMING OF PASSING WAVES AROUND THIS UPPER LOW...THERE ARE SOME DIFFERENCES IN THE STRENGTH OF THESE EMBEDDED WAVES. IN ADDITION...THE 00Z/02 MODEL RUNS ARE NOW MORE LIKE LAST NIGHT/S 00Z/01 RUN OF THE ETA PUSHING THE UPPER LOW SOUTHWARD. AS A RESULT...EMBEDDED WAVES/UPPER JET STREAKS ARE NOW PROGGED TO PASS THROUGH EASTERN KENTUCKY AS OPPOSED TO OUR NORTHWEST. THIS HAD LED TO AN INCREASE IN POPS TODAY THROUGH MONDAY IN THE FORECAST. FOR THE NEAR TERM...WE ARE MONITORING COMPLEX OF STORMS ACROSS WESTERN KENTUCKY EARLY THIS MORNING. IR SAT PICS SHOW CLOUD TOPS ARE NOT WARMING...SO WOULD EXPECTED THIS COMPLEX TO MARCH EASTWARD (PER CORFIDI VECTORS) AND MAKE INTO OUR FORECAST AREA THIS MORNING WITH LOW LEVEL THETA-E RIDGE IN PLACE. THEREFORE HAVE RAISED POPS...ESPECIALLY IN THE WEST. LEANED TOWARD COOLER GUIDANCE VALUES FOR HIGHS TODAY WITH EXPECTED PCPN AND ASSOCIATED CLOUDS. INCREASED POPS SATURDAY NIGHT...AS UPPER LEVEL WINDS AND UPPER DIVERGENCE INCREASE WITH WAVE PASSING JUST TO OUR NORTHWEST...PLACING US IN FAVORABLE RR QUAD OF UPPER JET. DIFFLUENT UPPER FLOW PERSISTS SUNDAY AS WELL AS EASTERN KENTUCKY WILL RESIDE UNDER 70+ KT UPPER LEVEL JET. THUS...ONCE AGAIN INCREASED POPS. SAME STORY FOR SUNDAY NIGHT AND MONDAY...AS ETA/GFS KEEP US UNDER UPPER DIVERGENT FLOW AND WOULD EXPECT A GOOD CHANCE FOR TSRA UNTIL UPPER TROF AXIS PASSES SOMETIME MONDAY NIGHT. .JKL...NONE. HYSELL --------------------------------------------------------------------- PREVIOUS DISCUSSIONS FOLLOW --------------------------------------------------------------------- 944 PM EDT FRI AUG 1 2003 SOME CONCERN THAT FORECASTED LOW TEMPS MAY NOT BE QUITE LOW ENOUGH FOR THE OVERNIGHT PERIOD. TEMPS IN SOME OF THE VALLEY LOCATIONS DROPPING FAIRLY QUICKLY WITH MOSTLY CLEAR SKIES EARLY TONIGHT. HOWEVER...SATELLITE SHOWING HIGHER CLOUDS FROM WESTERN CONVECTIVE ACTIVITY GRADUALLY MOVING INTO REGION...EVEN WITH SOME EROSION EVIDENT. MODELS/GUIDANCE ALSO SHOW SOME MID TO HIGH LEVEL CLOUDS MOVING IN BY 9-12Z...AGAIN APPARENTLY DEBRIS LEFT OVER FROM CONVECTIVE ACTIVITY TO OUR WEST. SATELLITE DOES SHOW SOME MID LEVEL CLOUDS OVER IL/IN. OBS INDICATING SCT TO BKN BETWEEN 6 AND 10K FT. WITH THIS IN MIND...FOG DEVELOPMENT MAY BE LIMITED AND TEMPS MAY NOT HAVE TOO MUCH OF AN OPPORTUNITY TO DROP MUCH MORE THAN FORECASTED. CONSEQUENTLY...TEMPS AND PATCHY FOG LOOK ON THE MARK FOR NOW. SO NO UPDATE TO FORECAST PLANNED FOR NOW. RAY --------------------------------------------------------------------- 240 PM EDT FRI AUG 1 2003 FOCUS OF THIS FORECAST IS PRECIPITATION CHANCES FOR THE NEXT SEVERAL DAYS. NGM...ETA...GFS AT 12Z THIS MORNING INITIALIZED THE POSITION OF THE 5H LOW OVER WESTERN END OF LAKE SUPERIOR AND THIS LOOKS GOOD. ALL MODELS AGREE ON MOVING THIS FEATURE VERY LITTLE THROUGH THE NEXT 48 HOURS. MODELS ALSO AGREE ON DEEPENING THE ASSOCIATED TROF EXTENDING SOUTH THROUGH THE MS VALLEY AS A SERIES OF SPEED MAXES AND VORT CENTERS MOVE THROUGH THE MEAN LONG WAVE TROF. WHILE SOME MINOR DIFFERENCES IN THE MODELS THE CONSENSUS IS THAT THE MAIN FOCUS FOR CONVECTIVE DEVELOPMENT WILL BE TO OUR W AND NW THROUGH SATURDAY...WITH BEST LIFT ASSOCIATED WITH RIGHT REAR QUADRANT OF JET STREAK. SUNDAY WILL SEE ERN KY IN BETTER POSITION WITH JET STREAK JUST TO OUR NORTH...AND US IN THE FAVORED RIGHT ENTRANCE REGION. WITH SLOW MOVEMENT OF MEAN UPPER TROF...THERE WILL BE VERY SLOW MOVEMENT OF COLD FRONT...AND FRONT WILL REMAIN TO OUR NW. WILL NEED TO HAVE CHANCE POPS IN THROUGH THE WEEKEND...WITH BEST CHANCE TO BE ON SUNDAY. UPPER TROF WILL CONTINUE TO DOMINATE OUR WEATHER THROUGH NEXT WEEK...AND PLAN TO KEEP DAILY CHANCE OF THUNDERSTORMS IN FORECAST THROUGH THURSDAY. TROF MAY SHIFT FAR ENOUGH EAST BY END OF NEXT WEEK...FOR A DRY FORECAST ON FRIDAY. WITH LITTLE CHANGE IN AIRMASS AND DEWPOINTS...LOWS WILL GENERALLY BE IN THE MIDDLE TO UPPER 60S THROUGH THE FORECAST...EXCEPT FOR A FEW OF THE NORMALLY COOLER SPOTS IN THE MOUNTAINS NEAR VIRGINIA. HIGHS WILL BE DEPENDENT ON AMOUNT OF SUN AND RAIN EACH DAY...BUT GENERALLY IN THE LOWER TO MIDDLE 80S. SBH --------------------------------------------------------------------- 1045 AM EDT FRI AUG 1 2003 MORNING FOG FINALLY STARTING TO LIFT ACROSS THE AREA. MAIN UPDATE WILL BE TO REMOVE THIS WORDING FROM THE ZONES. S/W TROUGH IN THE VICINITY HELPING TO KICK OFF SOME T-STORMS IN TENNESSEE...HOWEVER SO FAR CORES HAVE BEEN MEANDERING EAST AND STAYING SOUTHERN SIDE OF THE MOUNTAINS. WILL OPT TO KEEP POPS OUT FOR TODAY. WILL HANDLE ANY QUICK POP-UPS IN THE NEXT FEW HOURS OVER HIGHER TERRAIN AS S/W PULLS OUT WITH NOWCASTS. TRIGGERS FOR THE REMAINDER OF THE REGION AT THIS POINT LOOK FAR ENOUGH UPSTREAM TO KEEP FIRST PERIOD DRY...HOWEVER WILL HANDLE ANY BUOYANCY BUILD UPS WITH NOWCASTS AS WELL. FORECAST HAS THINGS TRENDED WELL AND WILL ONLY ADJUST A FEW HOURLY TEMPS IN THE GRIDS TO BETTER REFLECT CURRENT TRENDS. UPDATE OUT SHORTLY. GEOGERIAN
