AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE SPRINGFIELD MO 334 AM CDT MON AUG 23 2004 .DISCUSSION... SHORT TERM (TODAY AND TONIGHT)... THERE REMAINS A LOT OF UNCERTAINTY WITH THE THUNDERSTORM FORECAST FOR THIS AFTERNOON AND TONIGHT. MOISTURE HAS BEEN ON THE INCREASE FOR THE LAST COUPLE OF DAYS AND IT APPEARS AS THOUGH PWATS WILL INCREASE INTO THE 1.5 TO 1.75 RANGE OVER MUCH OF THE CWA THIS AFTERNOON. MEANWHILE...WATER VAPOR IMAGERY AND MID LEVEL PROFILE DATA SHOWS A COUPLE OF UPPER DISTURBANCES TRAVERSING ACROSS THE CENTRAL AND HIGH PLAINS. THIS MID LEVEL FORCING WILL PUSH INTO MISSOURI LATER TODAY. SEVERAL FEATURES COULD POSSIBLY COME TOGETHER OVER EASTERN KANSAS AND WESTERN MISSOURI THIS AFTERNOON FOR STRONG TO SEVERE THUNDERSTORMS. HOWEVER...IF CLOUD COVER REMAINS IN PLACE THROUGH MUCH OF THE DAY...THEN LOW END INSTABILITY WILL LIMIT SEVERE STORMS. WITH SURFACE WINDS BACKING AROUND TO THE SOUTHEAST AND 850 WINDS STRONG AND OUT OF THE SOUTHWEST...LOW LEVEL SHEAR WOULD SUPPORT ORGANIZED CONVECTION...IF AND ONLY IF STORMS CAN BECOME ROOTED WITHIN THE BOUNDARY LAYER. UPPER LEVEL WINDS WOULD ALSO BECOME FAVORABLE TO ENHANCE LARGE SCALE ASCENT WITH STRONG DIFFLUENCE PUSHING INTO THE EASTERN PLAINS. SEE THE HAZARDOUS WEATHER OUTLOOK FOR DETAILED INFORMATION ABOUT POSSIBLE THUNDERSTORMS TODAY AND TONIGHT. THE HIGH UNCERTAINTY ALSO EXISTS WITH TEMPERATURES TODAY...WHICH IS DEPENDENT UPON CLOUD COVER. MAV NUMBERS LOOK REASONABLE WITH MID 80S GOING ACROSS THE BOARD. FOR TONIGHT...THE AREA REMAINS UNDER THE INFLUENCE OF STRONG UPPER DIFFLUENCE. THIS COMBINED WITH LOW LEVEL JET WINDS MAY CONTINUE TO TRIGGER CONVECTION INTO THE OVERNIGHT PERIOD. MOST LOCATIONS WILL LIKELY REMAIN DRY HOWEVER. LONG TERM (TUESDAY - SUNDAY)... FINALLY IT APPEARS AS THOUGH AFTERNOON PULSE ACTIVITY WILL BE LIKELY ON A DAILY BASIS THROUGH MUCH OF THE WEEK. WITH BROAD TROUGHING OUT WEST AND SLIGHT RIDGING TO THE EAST...SOUTHWEST FLOW OVER THE OZARKS WILL BE FAVORABLE FOR TAPPING INTO THE DEEP SOUTH AIRMASS ALLOWING FOR AN INCREASE OF MOISTURE AND INSTABILITY. TEMPERATURES WILL BECOME VERY SEASONAL WITH AFTERNOON HIGHS IN THE UPPER 80S AND LOWER 90S...AND OVERNIGHT LOWS IN THE UPPER 60S AND LOWER 70S THROUGH FRIDAY. ADJUSTED THE GRIDS TO MENTION SHOWER AND THUNDERSTORM CHANCES IN THE DAY PERIODS. AS WE HEAD INTO THE WEEKEND...THE GFS AND ECMWF SHOW A COLD FRONT PUSHING INTO THE REGION. SUFFICIENT MOISTURE SHOULD BE AVAILABLE FOR A GOOD ROUND OF SHOWERS AND THUNDERSTORMS WITH THIS SYSTEM. LOOK FOR PRECIPITATION CHANCES TO TREND HIGHER FOR SATURDAY AS THE WEEK PROGRESSES. CRAMER && .AVIATION... SCATTERED SHOWERS AND THUNDERSTORMS HAVE DEVELOPED OVER SOUTHEAST KANSAS DURING THE PAST COUPLE OF HOURS AHEAD OF A WEAK SHORTWAVE AND WHERE LOW LEVEL SOUTHWESTERLY 850MB HAS ALSO INCREASED TO AROUND 25 KTS. META INDICATES A COMPLICATED MIDLEVEL FLOW WITH SUBTLE SHORTWAVES. A STRONGER SHORTWAVE FARTHER WEST OVER WESTERN KS WILL MOVE INTO EASTERN KS KATE THIS MORNING PRODUCING MORE WIDESPREAD RAINFALL. WILL MAINTAIN TEMPO GROUPS WITH THUNDERSTORM CHANCES THROUGH MOST OF THE DAY WITH MVFR CEILINGS. DSA && .SGF WATCHES/WARNINGS/ADVISORIES... MO...NONE. KS...NONE. WFO SGF

AREAS AFFECTED AND TIMING: MARGINALLY SEVERE THUNDERSTORMS WILL BE POSSIBLE LATE THIS MORNING AND THIS AFTERNOON ACROSS ALL OF EXTREME SOUTHEAST KANSAS AND THE MISSOURI OZARKS.
