AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE JACKSON KY 245 AM EDT SUN AUG 3 2003 LATEST WATER VAPOR SAT PICS ONCE AGAIN SHOW PERSISTENT UPPER LOW SPINNING NEAR LAKE SUPERIOR...AND THIS MORNING/S FORECAST CONCERNS ARE AGAIN TIMING PCPN CHANCES WITH ASSOCIATED JET STEAKS/IMPULSES ROTATING AROUND THIS LOW. GFS AND ETA PROVIDE SLIGHTLY DIFFERENT SOLUTIONS ON THE EVOLUTION OF THIS UPPER LOW...WITH THE GFS OPENING UP THE LOW AND SWINGING TROF AXIS THROUGH OUR AREA MONDAY NIGHT...WHILE THE ETA KEEPS THE LOW CLOSED A LITTLE LONGER AND IS SLOWER WITH THE UPPER TROF PASSAGE. THE GFS HAS SHOWN A BETTER RUN TO RUN CONSISTENCY...BUT WITH UPPER JET ENERGY STILL PROGGED TO BE ON THE WESTERN SIDE OF THE TROF...SLOWER/STRONGER ETA SOLUTION CERTAINLY POSSIBLE. FOR THIS FORECAST...USED A BLEND OF THE GFS/ETA FOR TIMING OF UPPER TROF PASSAGE. FOR TODAY...WATCHING NEXT SHORTWAVE ROTATE THROUGH SRN IL ATTM. GFS/ETA AGREE THAT THIS WAVE AND ASSOCIATED UPPER DIVERGENCE SWING THROUGH TO THE NORTH EARLY IN THE DAY. AS A RESULT...PLACED HIGHEST POPS EARLY TODAY. WITH SOME SUN EXPECTED DURING THE AFTERNOON...LEANED TOWARD WARMER FWC GUIDANCE VALUES FOR HIGHS TODAY. LOWERED POPS TO CHANCE CATEGORY TONIGHT...AS BEST JET DYNAMICS APPEAR TO REMAIN TO OUR NORTH AND WEST. HOWEVER...BEST CHANCE OF PCPN MAY BE ON MONDAY...WITH MAIN UPPER TROF AXIS PUSHES INTO CENTRAL KY BY 00Z/TUES UNDER GOOD UPPER DIVERGENCE. AS A RESULT...INCREASED POPS IN THE NORTHWEST ZONES FOR MONDAY. WITH UNCERTAINTY OF THE TIMING OF THE UPPER TROF PASSAGE...KEPT CHANCE POPS LINGERING INTO MONDAY NIGHT. DROPPED POPS DOWN TO SLIGHT CHANCE IN THE WESTERN ZONES ON TUESDAY WITH UPPER TROF AXIS AND ASSOCIATED MID LEVEL COOL POOL WELL TO OUR EAST. .JKL...NONE. HYSELL --------------------------------------------------------------------- PREVIOUS DISCUSSIONS FOLLOW --------------------------------------------------------------------- 1024 PM EDT SAT AUG 2 2003 EARLIER CLUSTERS OF SHOWERS AND THUNDERSTORMS HAVE DIMINISHED. HOWEVER...SHOWERS HAVE MOVED INTO/DEVELOPED OVER THE WESTERN PART OF THE CWA RECENTLY DUE TO INCREASING UPPER DIVERGENCE ASSOCIATED WITH RIGHT ENTRANCE REGION OF 300 MB JET STREAK TO OUR NW. NOT MUCH LIGHTNING NOW...SO NOT REAL SURE THERE WILL BE MUCH IN THE WAY OF THUNDER...BUT THERE SHOULD BE DECENT COVERAGE OF SHOWERS OVERNIGHT GIVEN DEGREE OF MOISTURE (PWS OF 1.6 TO 1.7 PER ILN AND BNA 0Z SOUNDING DATA) AND UPPER LEVEL DYNAMICS. LOW TEMPS IN THE UPPER 60S LOOK ON TRACK. THEREFORE...NO UPDATE IS PLANNED. PELTON --------------------------------------------------------------------- 316 PM EDT SAT AUG 2 2003 CURRENT SAT AND RADAR PICS INDICATE COMPLEX OF STORMS OFF TO THE WEST IN RESPONSE TO S/W SPAWNED FROM OUR FAVORITE UPPER LEVEL LOW SPINNING ITS WHEELS NEAR LAKE SUPERIOR. STORMS ARE POPPING UP IN FRONT OF IT...ALTHOUGH NOTHING HAS BEEN PUSHING SEVERE LIMITS. WET BULBS ARE PRETTY HIGH AND FLOW RELATIVELY UNIDIRECTIONAL. THIS COMPLEX WILL WORK IN BY SUNSET. WHILE MODELS REMAIN IN DECENT AGREEMENT WITH UPPER LEVEL SYSTEM...TIMING OF EMBEDDED WAVES AND JET STREAKS WILL CONTINUE TO BE PROBLEMATIC. GENERAL CONSENSUS OF ANOTHER MCS PROGGED TO IMPACT US AFTER MIDNIGHT TONIGHT AS FAVORABLE DIVERGENT REGION OCCURS AS NEXT INCOMING JET STREAK PULLS OUT. HAVE INCLUDE LIKELY POPS FOR TONIGHT AND INTO TOMORROW MORNING. SOME HEAVIER RAINERS A DEFINITE POSSIBILITY AS DEEP MOISTURE WILL BE PRESENT...HOWEVER WITH GUIDANCE VALUES NOT IN TOO MUCH TROUBLE ESPECIALLY IN THE NORTHERN HALF OF THE CWA...FEEL THAT ANY HYDRO PROBLEMS WILL BE ISOLATED AND THEREFORE WILL NOT HAVE A FLOOD WATCH GOING. 5H LOW WILL SPIN SOUTHWARD AND BRING MORE EMBEDDED WAVES TOWARDS US. TIMING OF THESE WILL BE KEY. DECIDED TO GO WITH PERSISTENCE AND KEPT 40 POPS GOING FOR MONDAY AND TRENDED BACK TO 30 POP FOR THE MID WEEK...AS UPPER LEVEL DYNAMICS SLACKEN. WENT AHEAD AND INSERTED A SLIGHT CHANCE POP FOR FRIDAY AS TROUGH AXIS DOES REMAIN IN THE VICINITY. GEOGERIAN PREVIOUS DISCUSSIONS FOLLOW --------------------------------------------------------------------- 1045 AM EDT SAT AUG 2 2003 14Z SFC ANALYSIS SHOWS LOW PRESSURE OVER WISCONSIN WITH A COLD FRONT STRETCHING SOUTHWEST INTO THE PLAINS AND A WARM FRONT WELL NORTH OF THE OHIO VALLEY. SOUTH OF THIS...THE DYING REMAINS OF THE EARLIER MCS HAS LEFT A BOUNDARY THROUGH EAST KENTUCKY WITH ANOTHER MCS SLOWLY INBOUND FROM THE WEST. ON SATELLITE THE EARLIER CLEARING IN THE WAKE OF THE MCS HAS STARTED TO SELF DESTRUCT WITH CU FILLING THE HOLES. TEMPS ARE OFF TO A SLOW START WITH THE EARLIER RAIN AND CLOUDS...BUT SHOULD HAVE NO PROBLEM REACHING THEIR HIGHS. THE NEXT SHORTWAVE...AND REMAINS OF THE CURRENT MCS...WILL BE APPROACHING DURING THE EVENING AND LIKELY PROVIDE ANOTHER ROUND OF ORGANIZED CONVECTION. IN THE MEANTIME...THE DIURNAL TREND WILL DOMINATE FOR THE AFTERNOON SO WILL UPDATE TO BRING POPS BACK TO THE CHANCE CATEGORY AND TINKER WITH CLOUD COVER IN THE GRIDS. UPDATES TO THE GRIDS...GRAPHICS AND TEXT PRODUCTS OUT SHORTLY. GREIF ---------------------------------------------------------------------
