NWS Springfield, MO wrote its last area forecast discussion before the first event at Sep 15, 1:21 PM CST, 3 hours 39 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE SPRINGFIELD MO 221 PM CDT TUE SEP 15 2009 .SHORT TERM (TONIGHT THROUGH THURSDAY NIGHT)... CUT OFF UPPER LEVEL LOW REMAINS TO THE SOUTHWEST OF THE AREA...AND SCATTERED SHOWERS CONTINUE TO MOVE AND DEVELOP ACROSS SOUTHERN MISSOURI AND NORTHERN ARKANSAS THIS AFTERNOON. CHANCES FOR SCATTERED SHOWERS WILL CONTINUE INTO THE OVERNIGHT HOURS...AS ENERGY ROTATES AROUND THE LOW INTO AREA WHERE A MOIST AIR MASS RESIDES. THERE MAY BE ENOUGH INSTABILITY IN PLACE ACROSS FAR SOUTHERN MISSOURI FOR AN ISOLATED THUNDERSTORM OR TWO BUT OVER ALL JUST SHOWER ACTIVITY IS EXPECTED. AN UPPER LEVEL TROUGH WILL MOVE THROUGH THE GREAT LAKES REGION INTO THE NORTHEASTERN U.S. TONIGHT INTO TOMORROW. THIS WILL SEND A DRIER AIR MASS TOWARDS THE AREA. THERE IS SOME QUESTION ON JUST HOW FAR SOUTH IT CAN REACH OVERTAKING THE MOIST AREA MASS OVER THE AREA. HAVE FOLLOWED MORE IN LINE WITH THE ECMWF WHICH LIMITS PRECIPITATION CHANCES TO FAR SOUTHERN MISSOURI TOMORROW THROUGH THURSDAY AS THE DRIER AIR MASS OVERTAKES MUCH OF THE AREA. SCATTERED SHOWERS WILL BE POSSIBLE ACROSS SOUTHERN MISSOURI AS THE LOW WILL NOT MOVE ALL THAT FAR SOUTH. SCATTERED SHOWERS WILL REMAIN ACROSS SOUTHERN MISSOURI WITH THE BETTER CHANCES ACROSS ARKANSAS TOMORROW THROUGH THURSDAY. THE INCREASED CLOUD COVER WILL HELP KEEP TEMPERATURES BELOW NORMAL THROUGH THE SHORT TERM. WISE && .LONG TERM (FRIDAY THRU TUESDAY)... THE MODELS CONTINUE TO STRUGGLE WITH THE EXTEND FORECAST AS NOTED BY THE DIFFERENCES IN PRECIPITATION CHANCES BETWEEN THE GFS AND ECMWF. LOOKING AT THE NOGAPS OFFERED NO HELP EITHER. DID NOTE THAT THE 12Z GFS IS LOOKING MORE LIKE THE ECMWF FOR THE WEEKEND WITH PRECIPITATION SPREADING NORTH ACROSS THE OZARKS LATE SATURDAY INTO SUNDAY. OF NOTE ARE THE GFSBUFR/ECMWF/GFS SOUNDINGS FOR THE AFOREMENTIONED PERIOD. ALL OF THE SOUNDINGS ARE INDICATING PW VALUES IN THE 1.25 TO 1.75 INCH RANGE AND NEARLY SATURATED COLUMNS FROM SURFACE TO 300MB PLUS CENTERED ON 00Z SUNDAY. WHILE THINGS LOOK TO BE MOISTENING UP...THIS IS THE FIRST RUN WITH SOME CONSISTENCY BETWEEN THE MODELS AND THE 12Z ECMWF IS YET TO COME IN. HAVE TEMPERED THE POPS AND TEMPERATURES OVER THE WEEKEND DUE TO THE LEVEL OF INCONSISTENCY AND WILL NEED TO MONITOR OVER THE NEXT SEVERAL RUNS. THE WEATHER FOR EARLY NEXT WEEK HOWEVER DOES LOOK WET AS A THE UPPER LEVEL LOW THAT HAS RESIDED OVER THE SOUTH CENTRAL U.S. WILL PHASE WITH A STRONG UPPER LEVEL SYSTEM. THIS WILL BRING A POTENTIALLY POTENT SYSTEM THROUGH THE REGION MONDAY INTO TUESDAY. THERE ARE DIFFERENCES BETWEEN THE GFS AND THE ECMWF WHICH BRING A DEEP OPEN LONG WAVE TROF AND A DEEP CLOSED LOW ACROSS THE AREA RESPECTIVELY. REGARDLESS OF WHICH OCCURS...FELL THAT A PRETTY GOOD STORM SYSTEM WILL PUSH THROUGH THE OZARKS. OF COURSE THIS IS TOWARDS THE END OF THE FORECAST PERIOD BUT WILL CONTINUE TO MONITOR AND ADJUST ACCORDINGLY. HATCH && .AVIATION... THE PRIMARY FORECAST CHALLENGE WILL BE MVFR AND IFR CEILINGS THROUGH THE PERIOD. CEILINGS ACROSS THE AREA THIS AFTERNOON... WITH THE EXCEPTION OF BRANSON... HAVE BEEN VFR OUTSIDE PRECIPITATION WITH MVFR WITH PRECIPITATION. BRANSON HAS BEEN SOCKED IN AT AROUND 300 FT ALL DAY WITH PERSISTENT NORTHEASTERLY UPSLOPE FLOW. THIS WILL LIKELY CONTINUE WITH A STEADY MOISTURE STREAM OVER THE AREA ON THE NORTHEAST SIDE OF THE LOW CENTERED TO THE SOUTH. TIMING OF RAINFALL WILL BE VERY PROBLEMATIC DO TO THE SPOTTY NATURE OF THE PRECIP. NAM MOS SEEMED TO HAVE THE BEST HANDLE ON THE SITUATION OVERNIGHT SO USED IT AS PRIMARY GUIDANCE.
