NWS Springfield, MO wrote its last area forecast discussion before the first event at Aug 2, 3:03 AM CST, 1 hour 57 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE SPRINGFIELD MO 403 AM CDT SAT AUG 2 2003 .DISCUSSION... UNSEASONABLY STRONG GREAT LAKES CYCLONE CONTINUES TO SIT AND SPIN AND HAS CREATED SOME UNSETTLED WEATHER ACROSS THE NATIONS MID SECTION THE LAST FEW HOURS. THE APPROACH OF AN UPPER LEVEL SPEED MAX AND STRONG 850 MB MOISTURE SURGE INTO SOUTHEAST KANSAS HAS PROVIDED THE NECESSARY INGREDIENTS FOR STRONG TO SEVERE STORMS THIS MORNING. LOOK FOR STORMS TO CONTINUE THROUGH A GOOD PORTION OF TODAY AND ALL FORECAST ELEMENTS IN THE FIRST PERIOD WILL BE THE PRIMARY FORECAST CHALLENGE. SHORT TERM (TODAY - MONDAY) MESO ETA IS NOT QUITE AS AGGRESSIVE WITH PUSHING SURFACE BOUNDARY THROUGH SOUTHERN MISSOURI AS PREVIOUS RUNS. ETA IS CERTAINLY THE MODEL OF CHOICE AND SHORT TERM FORECAST WILL BE WEIGHTED HEAVIEST WITH THE MESO ETA OUTPUT. THE INITIAL CHALLENGE IS THE ONGOING CONVECTION AND HOW THIS WILL MODIFY TODAYS FORECAST. CONVECTIVE CLUSTER SOUTH OF THE PLATEAU IS FINALLY HEADING SOUTH TOWARD THE ARKANSAS STATE LINE...HOWEVER...SCATTERED ACTIVITY HAS REDEVELOPED NORTH OF THE MAIN COMPLEX. OTHER CLUSTERS HAVE DEVELOPED OVER SOUTHERN KANSAS AND THIS ACTIVITY WILL LIKELY AFFECT EXTREME SOUTHWEST MISSOURI WITHIN THE FIRST PERIOD. LOW LEVEL BOUNDARY HAS BECOME ALMOST QUASI-STATIONARY AND MESO ETA SOUNDING PROGS SHOW SURFACE BASED CAPES OF AROUND 3000 J/KG THIS AFTERNOON. SO FIRST PERIOD FORECAST WILL CONTAIN THUNDERSTORM CHANCES ACROSS THE BOARD FOR THIS MORNING AND THIS AFTERNOON. WITH WARM AND UNSTABLE AIRMASS LINGERING ACROSS SOUTHERN MISSOURI...WILL HAVE TO INTRODUCE PRECIP CHANCES INTO SATURDAY NIGHT AND SUNDAYS FORECAST AS WELL. OVERALL SYNOPTIC PATTERN AMPLIFIES TO A DEGREE...AND 200 MB SPEED MAX PIVOTS IN MORE OF A NORTH TO SOUTH FASHION. CWA REMAINS IN A STRONG AREA OF UPPER LEVEL DIFFLUENCE POSITIONED UNDER THE LEFT EXIT REGION OF THIS FEATURE. THIS IN CONJUNCTION WITH A COUPLE OF DEVELOPING MID LEVEL DISTURBANCES WILL PROVIDE ENOUGH FORCING FOR REDEVELOPMENT OF CONVECTION. LONG TERM (TUESDAY - FRIDAY)... TWO MAIN SYNOPTIC FEATURES CONTROLLING THE UPPER FLOW WILL GRADUALLY SHIFT EAST NEXT WEEK. ECMWF IS A LITTLE MORE AGGRESSIVE WITH BUILDING IN THE UPPER RIDGE OVER THE HIGH PLAINS AND PROGRESSING EASTERN CONUS TROUGH TOWARDS THE COAST. IN EITHER CASE...THE NATIONS MID SECTIONS REMAINS UNDER THE INFLUENCE OF NORTHWEST FLOW. ONGOING EXTENDED FORECASTS LOOKS LIKE ITS IN GREAT SHAPE AND SEE NO REASON TO MAKE ANY DRASTIC CHANGES. CHALLENGES AS ALWAYS WILL EXIST IN TIMING ANY DISTURBANCES RIDING DOWN THE NORTHWEST FLOW...WHICH WILL BECOME MORE APPARENT WITH TIME. TWEAKED TEMPS AND CLOUD COVER SOME TO BLEND IN BETTER WITH SURROUNDING OFFICES. .AVIATION... CLUSTERS OF CONVECTION CONTINUE TO AFFECT AREAS OF SOUTHEAST KANSAS AND THE SOUTHWEST MISSOURI THIS MORNING. EXPECT THIS ACTIVITY TO SLOWLY DRIFT SOUTHWARD AS THE MORNING PROGRESSES...POSSIBLY REDEVELOPING THIS AFTERNOON. A COLD FRONT WILL LINGER ACROSS THE REGION THE NEXT 24 TO 48 HOURS...CONTINUING THUNDERSTORM CHANCES INTO SUNDAY. .SGF WATCHES/WARNINGS/ADVISORIES... .MO...NONE. .KS...NONE. CRAMER

AREAS AFFECTED AND TIMING: ALL OF EXTREME SOUTHEAST KANSAS AND THE MISSOURI OZARKS THROUGH THE OVERNIGHT HOURS. DISCUSSION: STRONG TO SEVERE THUNDERSTORMS WILL CONTINUE TO ERUPT ACROSS THE REGION THROUGH THE PRE-DAWN HOURS. THE COMBINATION OF A STRONG LOW LEVEL MOISTURE SURGE AND AN APPROACHING JET MAX ALOFT WILL PROVIDE NECESSARY INGREDIENTS FOR RAPIDLY DEVELOPING SEVERE THUNDERSTORMS. THESE STORMS WILL LIKELY EVOLVE INTO A CLUSTER THE NEXT FEW HOURS...AND THE TRAINING OF STORMS OVER SPECIFIC LOCATIONS IS LIKELY. THIS WILL LEAD TO INCREASED FLASH FLOOD POTENTIAL ESPECIALLY OVER THE ROCKY TERRAIN OF THE OZARK HILLS. STRONG DIRECTION CHANGE WITH WINDS ALOFT WILL ALLOW SOME OF THESE STORMS TO MAINTAIN ROTATING UPDRAFTS FOR LONG PERIODS OF TIME. OTHER THAN FLASH FLOODING...HAIL UP TO THE SIZE OF HALF DOLLARS AND STRONG WIND GUSTS IN EXCESS OF 70 MPH WILL ACCOMPANY THE STRONGER STORMS. .DAYS TWO THROUGH SEVEN...SUNDAY THROUGH FRIDAY.
