NWS Springfield, MO wrote its last area forecast discussion before the first event at Aug 30, 2:05 AM CST, 1 hour 13 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE SPRINGFIELD MO 305 AM CDT SAT AUG 30 2003 ...SIGNIFICANT RAINFALL AND POSSIBLE FLOODING STILL ON TAP THROUGH THE LABOR DAY WEEKEND... .DISCUSSION... WOULD FIRST LIKE TO THANK THE EL TECH STAFF AND RADAR OPERATIONS CENTER FOR THEIR ROUND-THE-CLOCK EFFORTS OVER THE PAST SEVERAL DAYS...RESTORING THE RADAR TO SERVICE AROUND 1 AM. ALTHOUGH THE DATA LOOKS QUITE REASONABLE...PLEASE USE DATA AND DERIVED PRODUCTS WITH CAUTION THROUGH THIS MORNING UNTIL THE 88D IS RECALIBRATED. WEATHER WISE...RADAR SCOPE IS MUCH QUIETER THAN I HAD ANTICIPATED AT THIS TIME LAST NIGHT...ALTHOUGH COVERAGE IS REALLY ON THE INCREASE OVER THE LAST HOUR. PROFILER DATA REALLY TELLS THE STORY WITH STRONGEST CONVERGENCE JUST EAST OF WEAK UPPER LOW OVER SWRN KS...AIDED BY MODEST ISENTROPIC UPGLIDE AND SRLY LOW LEVEL JET. MEANWHILE...LIGHT FLOW REGIME WAS IN PLACE OVER THE OZARKS REGION ALTHOUGH RECENT INCREASE IN LOW LEVEL VEERING AT CONWAY PROFILER SUGGESTIVE THAT WEAK WARM AIR ADVECTION WAS RESPONSIBLE FOR THE RECENT CONVECTIVE FLARE-UP OVER SRN MO. 00Z KSGF SOUNDING SHOWS DEEP TROPICAL AIRMASS IN PLACE WITH A THERMODYNAMIC PROFILE THAT IS BOTH MOIST-ADIABATIC AND NEARLY SATURATED. PWATS NOW APPROACHING 2 CERTAINLY SUGGEST EXCESSIVE RAINFALL POTENTIAL -- IF WE CAN GET A HOLD OF A FORCING MECHANISM. FOR TODAY...REALLY NOT ALL THAT IMPRESSED WITH OVERALL PRECIPITATION CHANCES. LARGE SCALE ASCENT WILL REMAIN ACROSS OK/KS...WITH FAR WRN COUNTIES SEEING THE ONLY POTENTIAL FOR WIDESPREAD/HEAVY PRECIPITATION AS THIS SYSTEM MOVES SLOWLY EAST THIS AFTERNOON. ACROSS THE REMAINDER OF THE CWA...ONGOING CONVECTION SHOULD GRADUALLY DISSIPATE THIS MORNING...AND EXPECT LIGHTNING COUNT TO WANE AS CONVECTION MOVES NORTH INTO MORE STABLE AIRMASS. SCATTERED AFTERNOON SHOWERS PRETTY MUCH THE RULE OVER ERN 2/3RDS OF CWA. MUCAPES ONLY 300 J/KG AT BEST OVER SRN MO...BUT WILL LEAVE IN MENTION OF ISOLATED THUNDER AS I DO THINK WE MAY SEE PARTIAL SUNSHINE AGAIN THIS AFTERNOON TO ENHANCE BOUNDARY LAYER INSTABILITY. TEMPERATURES AGAIN HELD IN CHECK BY EXTENSIVE CLOUD COVER AND SATURATED AIRMASS...WITH DIURNAL RANGES GENERALLY LESS THAN 10 DEGREES. PRECIPITATION AXIS AGAIN SHIFTS JUST TO OUR WEST TONIGHT AS SERLY LOW LEVEL JET INTERACTS WITH FRONTAL ZONE AND UPPER TROUGH AXIS...HOWEVER WRN COUNTIES WILL LIKELY BE WITHIN THE EASTERN FRINGES OF HEAVY RAINFALL. AGAIN HAVE PAINTED POPS/QPF WITH A LARGE WEST TO EAST GRADIENT. STILL LOOKS LIKE THE MAIN SHOW WILL BE ON SUNDAY-MONDAY AS A COMBINATION OF STRONG SIGNALS SUGGEST A SIGNIFICANT EXCESSIVE RAINFALL EVENT. UPPER TROUGH WILL AMPLIFY JUST WEST OF THE OZARKS AS A RATHER POTENT SHORTWAVE DROPS IN FROM THE CENTRAL ROCKIES. MEANWHILE...LARGE TUTT (TROPICAL UPPER TROPOSPHERIC TROUGH) CELL WAS WELL DEPICTED IN WATER VAPOR IMAGERY OVER THE NWRN GULF OF MEXICO AND WILL GRADUALLY MOVE NORTH INTO ERN OK. EAST OF THIS SYSTEM...COPIOUS AMOUNTS OF TROPICAL MOISTURE WILL SURGE NORTH INTO THE OZARKS ON A 35-40 KT CROSS-GULF LOW LEVEL JET RESULTING IN EXTREME MASS CONVERGENCE ALONG QUASI-STATIONARY FRONT. IMPRESSIVE UPPER LEVEL DIVERGENCE FIELDS ALSO DEPICTED IN MODEL SOLUTIONS AS ISOTACH GRADIENT INCREASES UNDER RIGHT REAR QUADRANT OF STRONG JET STREAK OVER NEW ENGLAND. COMBINATION OF PRECIPITABLE H20 VALUES WELL IN EXCESS OF TWO INCHES AND PROJECTED SLOW CELL MOVEMENT WOULD SUGGEST THAT CONDITIONS ARE PRIME FOR A PROLONGED HEAVY RAINFALL EVENT SPREADING OVER THE CWA SUNDAY INTO EARLY MONDAY. THEREFORE... CONCERNING THE FLOOD WATCH...SEE NO REASON TO DROP IT AT THIS POINT ONLY TO REISSUE TONIGHT. WILL EXTEND IT THROUGH SUNDAY (UNDER FLS HEADER) AND EXPLAIN REASONING WITHIN. ALSO...IT IS IMPORTANT TO NOT OVERLOOK SEVERE POTENTIAL ON SUNDAY WITH UNUSUAL INLAND PLACEMENT OF TUTT LOW OVER ERN OK. IF ENOUGH DAYTIME HEATING CAN OCCUR...CANNOT RULE OUT POTENTIAL FOR ISOLATED TORNADOES. THIS MAY SEEM A BIT OF A STRETCH...HOWEVER STRONG LOW LEVEL DIRECTIONAL/SPEED SHEAR OVER THE REGION IS MORE THAN SUFFICIENT FOR LOW-TOPPED TROPICAL SUPERCELLS OVER THE REGION...WITH FORECAST SOUNDINGS/HODOGRAPHS RESEMBLING THOSE OF LANDFALLING TROPICAL SYSTEMS. NEW DAY 2 CONVECTIVE OUTLOOK FROM SPC ALSO ALLUDES TO THIS THREAT. PRECIPITATION SHIELD WILL GRADUALLY CLEAR FROM WEST TO EAST LATE MONDAY AS 500MB TROUGH AXIS SWEEP ACROSS THE AREA. REMAINDER OF THE PACKAGE LOOKS TO BE IN GOOD SHAPE AT THIS POINT. && .AVIATION... MAIN AVIATION CONCERN WILL BE PATCHY FOG AND CONVECTIVE ACTIVITY DURING THE 06Z TAF CYCLE. FRONTAL BOUNDARY HAS PUSHED SOUTH OF THE AREA BUT DRIER AIR MASS LAGGING WELL BEHIND THE FRONT WITH DEW POINTS STILL IN THE LOW 70S IN FORECAST AREAS. MAIN CONVECTION WAS DEVELOPING ALONG THE FRONT FURTHER SOUTH IN OKLAHOMA AND STRETCHING INTO SOUTHEAST MISSOURI...HOWEVER SOME OF THIS CONVECTION HAS DRIFTED TOWARDS JLN AND WILL BE A FORECAST CONCERN DURING FORECAST TIME FRAME. SEVERAL UPPER WAVES WILL PUSH THROUGH THE AREA WHICH WILL REMAIN IN THE MOIST ATMOSPHERE AND WILL ENHANCE THE CONVECTIVE CHANCES DURING THE PERIOD. CEILINGS SHOULD REMAIN ABOVE 3000 FEET IN THE TERMINALS WITH VISIBILITIES POSSIBLY DROPPING TO 3 MILES WITH RAIN AND FOG AS THE RESTRICTORS. && .SGF... .MO...FLOOD WATCH ALL ZONES THROUGH SUNDAY. .KS...FLOOD WATCH ALL ZONES THROUGH SUNDAY.

WEATHER HAZARDS EXPECTED: ISOLATED THUNDERSTORMS WHICH COULD PRODUCE LOCALLY HEAVY RAINFALL OF 1 TO 2 INCHES. AREAS AFFECTED AND TIMING: ISOLATED THUNDERSTORMS WILL BE POSSIBLE REGION WIDE THIS EVENING. DISCUSSION: WEAK CONVERGENCE AHEAD OF AN APPROACHING COLD FRONT MAY BE SUFFICIENT TO TRIGGER ISOLATED THUNDERSTORMS TONIGHT. HIGH MOISTURE LEVELS IN THE ATMOSPHERE ARE CONDUCIVE TO VERY HEAVY RAIN WITH ANY STORMS THAT DO FORM. .DAYS TWO THROUGH SEVEN...SATURDAY THROUGH THURSDAY. SEVERAL ORGANIZED CLUSTERS OF THUNDERSTORMS MAY DEVELOP ALONG THE STATIONARY FRONT THROUGH LABOR DAY. LOCALLY HEAVY RAINFALL WILL BE THE MAIN CONCERN...LEADING TO AN INCREASED FLOOD THREAT THIS WEEKEND. RAINFALL WILL GRADUALLY END FROM WEST TO EAST ON MONDAY. .SPOTTER INFORMATION STATEMENT...
