Area forecast discussion, Aug 1, 1:33 PM CDT, 52 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE SPRINGFIELD MO 133 PM CDT FRI AUG 1 2003 ...MODERATE RISK OF SEVERE THUNDERSTORMS THIS AFTERNOON... .MESOSCALE CONVECTIVE DISCUSSION... LATEST VISIBLE SATELLITE IMAGERY (THANKS NCEP FOR RSO) DEPICTING EXPANSE OF CIRRUS DEBRIS OVER THE AREA PRESENTLY IS SHOWING CONTINUED SIGNS OF DISSIPATION AND ALLOWING FOR RAPID BOUNDARY LAYER HEATING OVER MUCH OF THE AREA. TEMPERATURES HAVE RESPONDED QUITE WELL TO THIS TREND...AND ARE APPROACHING OR HAVE EXCEEDED 90 DEGREES IN MOST LOCATIONS. PRELIMINARY GANDER AT ONGOING 18Z KSGF SOUNDING SHOWS THAT ADVECTION OF LOW LEVEL TROPICAL MOISTURE HAS BEEN VERY EFFECTIVE THIS MORNING...AND MLCAPES ARE QUICKLY APPROACHING 3000 J/KG WITH LITTLE IN THE WAY INHIBITION LEFT. LATEST 8-BIT 88D IMAGERY SHOWS HORIZONTAL CONVECTIVE ROLLS BEGINNING TO SHOW UP...OFTEN A PRECURSOR TO ISOLATED THUNDERSTORM DEVELOPMENT OVER REMNANT BOUNDARIES FROM YESTERDAY. MEANWHILE...CONVECTIVE OUTFLOW FROM ELEVATED ACTIVITY OVER NRN MO HAS BEGUN TO ENTER FAR NRN PORTIONS OF THE CWA AS INDICATED BY A THIN BAND OF CU ON SATELLITE AND STREAMLINE ANALYSIS OF LOCAL MESONET DATA. LOW LEVEL AIRMASS OVER CENTRAL MO REMAINS DRY...AND THEREFORE WILL TAKE QUITE A BIT TO OVERCOME INHIBITION. EXPECT INITIATION TO TAKE PLACE FIRST OVER FAR WRN PORTIONS OF THE BOUNDARY WHERE LOW LEVEL AIRMASS IS FAR MORE SUITABLE. ALSO MONITORING CONVECTIVE TRENDS ALONG WELL DEFINED NW-SE ORIENTED OUTFLOW OVER NORTH CENTRAL AND NE KANSAS. THUNDERSTORMS HAVE CONTINUED TO INCREASE IN COVERAGE...AND ALTHOUGH THEY ARE PRESENTLY ELEVATED IN NATURE...CONTINUED SOUTHWARD PROPAGATION WILL MOVE THE EFFECTIVE BOUNDARY INTO AN ATMOSPHERE THAT IS FAR MORE CONDUCIVE TO SURFACE BASED CONVECTION. CURRENT THINKING CONTINUES THE IDEA THAT STORMS WILL LIKELY DEVELOP OVER THE NEXT 1-3 HOURS...AND SHOULD RAPIDLY BECOME SEVERE. LATEST MANUAL ANALYSIS OF REGIONAL PROFILER DATA IN CONJUNCTION WITH OBJECTIVE RUC ANALYSIS INDICATES THAT 0-6KM DEEP LAYER SHEAR ON THE ORDER OF 40-45 KTS CONTINUES TO DIVE SOUTHEAST THROUGH KANSAS ON THE LEADING EDGE OF POTENT SHORTWAVE EVIDENT ON WATER VAPOR IMAGERY. THEREFORE...LARGE DESTRUCTIVE HAIL AND POTENTIAL FOR WIDESPREAD DAMAGING WINDS WILL BE THE MAIN THREATS GIVEN THE EXPECTED TREND TOWARD SUPERCELLULAR SHEAR PROFILES IN THE NEXT 3-6 HOURS. HIGH LCL HEIGHTS SHOULD PRECLUDE TORNADO THREAT...EVEN WITH REMNANT BOUNDARIES FROM YESTERDAYS ACTIVITY. .SGF WATCHES/WARNINGS/ADVISORIES... .MO...NONE. .KS...NONE. BOOKBINDER

THUNDERSTORM REDEVELOPMENT OVERNIGHT MAY LEAD TO PROLONGED TORRENTIAL RAINFALL AND LOCALIZED FLASH FLOODING. AREAS AFFECTED AND TIMING: THUNDERSTORMS ARE EXPECTED TO DEVELOP OVER MID MISSOURI INTO SOUTHEAST KANSAS AFTER 2 PM...AND THEN BUILD OVER THE REMAINDER OF THE OZARKS REGION DURING THE AFTERNOON AND EVENING HOURS. DISCUSSION: AN ALREADY UNSTABLE AIRMASS WAS IN PLACE ACROSS THE OZARKS REGION EARLY THIS AFTERNOON. DESPITE EXTENSIVE CLOUD COVER OVER THE AREA...FILTERED SUNSHINE HAD WARMED TEMPERATURES INTO THE UPPER 80S AND LOWER 90S. SOUTHWEST WINDS WILL CONTINUE TO BRING DEEP TROPICAL MOISTURE NORTH INTO THE AREA...AND SKIES WILL PARTIALLY CLEAR OVER THE NEXT SEVERAL HOURS ALLOWING FOR FURTHER DESTABILIZATION. MEANWHILE...A VIGOROUS UPPER LEVEL STORM SYSTEM WAS ENTERING CENTRAL KANSAS...ACCOMPANIED BY UNSEASONABLY STRONG WINDS ALOFT. THIS DISTURBANCE AND AN ASSOCIATED COLD FRONT WILL BE THE FOCUS FOR RAPID THUNDERSTORM DEVELOPMENT OVER FAR WESTERN MISSOURI AND EXTREME SOUTHEAST KANSAS BY MID AFTERNOON. THE COMBINATION OF STRONG VERTICAL WIND SHEAR AND HIGH INSTABILITY WILL CAUSE STORMS TO RAPIDLY BECOME SEVERE WITH THE POTENTIAL FOR WIDESPREAD DAMAGING WINDS AND LARGE DESTRUCTIVE HAIL OVER THE ENTIRE OUTLOOK AREA THROUGH TONIGHT. THUNDERSTORMS ARE EXPECTED TO GRADUALLY EVOLVE INTO ONE OR MORE LARGE COMPLEXES OVER THE AREA TONIGHT AS THE COLD FRONT STALLS OVER SOUTHERN MISSOURI...POSSIBLY LEADING TO FLASH FLOODING. BASED ON RECENT SATELLITE TRENDS...SEVERE WEATHER WATCHES MAY BE REQUIRED IN THE NEXT SEVERAL HOURS. .DAYS TWO THROUGH SEVEN...SATURDAY THROUGH THURSDAY. THUNDERSTORMS WILL LIKELY BE ONGOING ACROSS SOUTHERN MISSOURI EARLY SATURDAY MORNING...ESPECIALLY SOUTH OF THE INTERSTATE 44 CORRIDOR. SOME OF THESE STORMS MAY STILL BE SEVERE...WITH DAMAGING WINDS AND FLOODING RAINFALL THE PRIMARY THREATS. AS A FOCUSING COLD FRONT SHIFTS SOUTH INTO ARKANSAS SATURDAY AFTERNOON...THUNDERSTORMS WILL GRADUALLY EXIT THE AREA. ANOTHER UPPER LEVEL DISTURBANCE WILL BRING A CHANCE FOR THUNDERSTORMS TO THE REGION MONDAY NIGHT AND TUESDAY. .SPOTTER INFORMATION STATEMENT...
