AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE SPRINGFIELD MO 102 PM CDT MON AUG 10 2009 ...UPDATED AVIATION DISCUSSION... .UPDATE... THUNDERSTORMS CONTINUE TO EXPAND ROUGHLY ALONG AND EITHER SIDE OF A LINE FROM FORT SCOTT KS TO OSCEOLA TO THE LAKE OF THE OZARKS. SOUTH SOUTHWESTWARD MOVING OUTFLOW BOUNDARY CLEARLY SEEN ON KSGF WSR 88D IMAGERY. THE LOW LEVEL JET...BEST SEEN AROUND THE 925MB THIS MORNING...REMAINS PERPENDICULAR TO THIS BOUNDARY RIGHT NOW...THOUGH LOW LEVEL WINDS SHOULD VEER/WEAKEN WITH TIME LEADING TO A TREND OF DECREASING ACTIVITY. THE MAIN HAZARD WITH RAINFALL THIS MORNING ACROSS THE NORTHERN CWA WILL BE LOCALLY HEAVY RAINFALL. WITH A MYRIAD OF BOUNDARIES AROUND AND TEMPS EXPECTED TO REACH INTO THE UPPER 80S/LOWER 90S...ADDITIONAL DEVELOPMENT OF TSRA IS EXPECTED THIS AFTERNOON...PARTICULARLY ALONG THE INTERSTATE 44 CORRIDOR. SBCAPE SHOULD RISE ABOVE 3000 J/KG WITH MLCAPE IN EXCESS OF 2000 J/KG...THUS THERE IS A CONCERN FOR SCATTERED SEVERE STORMS WITH DOWNBURSTS THE PRIMARY ISSUE...HAIL IS A SECONDARY CONCERN. CHANCES FOR STORMS WILL ONCE AGAIN BE A CONCERN LATER TONIGHT AND TUESDAY AS WE WILL LIKELY BE ON THE RECEIVING END OF AN MCS FROM KS LATE TONIGHT/EARLY TUE. GAGAN && .DISCUSSION... FORECAST CHALLENGES CONTINUE TO DEAL WITH POP CHANCES AND TIMING IN THE SHORT TERM THAT WILL HAVE A HUGE IMPACT ON TEMPERATURES THIS AFTERNOON AND TUESDAY. THERE IS A VERY HIGH POSSIBILITY OF A FORECAST BUST WITH BOTH TEMPERATURES AND POPS FOR TODAY. CURRENTLY...SURFACE LOW CENTERED OVER NORTHEAST KANSAS JUST TO THE WEST OF TOPEKA THIS MORNING. COLD FRONT TO THE SOUTHWEST BISECTING KANSAS FROM NORTHEAST TO SOUTHWEST. CONVECTION ON MOSAIC RADAR CONCENTRATED OVER NORTHWESTERN MISSOURI AND SEEMS TO BE PERCOLATING ON PREVIOUS OUTFLOW BOUNDARIES. SOUTHWESTERN PORTION OF THE CONVECTION BEING FUELED BY 25-30KT LOW LEVEL JET AS CAN BE SEEN ON AREA PROFILERS. THIS JET SEEMS TO BE WEAKENING SOME OVER THE PAST COUPLE HOURS AND WILL NEED TO WATCH WHAT HAPPENS WHEN/IF THE JET WEAKENS ANY FURTHER. FOR TODAY...WILL CONTINUE TO MONITOR PROGRESS OF OUTFLOW BOUNDARIES TO THE SOUTH TO MAKE ANY LAST MINUTE CALLS ON POPS AND TEMPERATURES TODAY. FROM THE WRF THIS MORNING...INDICATIONS ARE THAT THE LOW LEVEL JET WILL PICK UP AGAIN LATER THIS MORNING AND SHIFT MORE WESTERLY...WHICH WOULD SHIFT CONVECTION FURTHER TO THE SOUTH AS OUTFLOW BOUNDARIES MOVE SOUTH. GFS ON THE OTHER HAND...REALLY WEAKENS THE JET AND ANY CONVECTION APPEARS TO BE ISOLATED TO SCATTERED ALONG THE FRONT AS IT STALLS OVER NORTHERN AND CENTRAL MISSOURI. HAVE DECIDED TO FOLLOW THE WRF/HPC SOLUTION AND BRING SHOWERS AND FRONT SOUTH INTO THE CWA THIS AFTERNOON AND WILL KEEP THE WET SOLUTION GOING. SHOULD THE GFS SOLUTION BEAR FRUIT...CWA WILL REMAIN DRY AT LEAST UNTIL THIS EVENING AND TEMPERATURES WILL CLIMB BACK INTO THE LOW TO MID 90S. TOOK A BLEND OF WRF AND GFS TEMPERATURES FOR TODAY AND HAVE UPPER 80S/LOW 90S FORECAST FOR HIGHS TODAY. SEVERE THUNDERSTORMS WILL BE A POSSIBILITY AS WELL THIS AFTERNOON...PARTICULARLY OUR SOUTHERN AND SOUTHEASTERN COUNTIES WHERE WRF FORECAST CAPES APPROACH 3000 J/KG AS THE LOW LEVEL CAP BREAKS. LOOK FOR HAZARDS TO BE MAINLY CONVECTIVE WINDS AND HAIL THIS AFTERNOON AND WILL INCLUDE IN THIS MORNINGS HWO. ALL MODELS ARE SHOWING A CONVECTIVE COMPLEX FORMING TONIGHT ACROSS EASTERN KANSAS AND MOVING EASTWARD INTO THE SGF CWA OVERNIGHT WITH SEVERE WEATHER THREATS TURNING TO HEAVY RAINFALL. GFS...THOUGH PROBABLY CONVECTIVE LY CONTAMINATED...IS FORECASTING SOME PRETTY HIGH RAIN AMOUNTS WITH THIS COMPLEX...ANYWHERE FROM 2 TO 4 INCHES WITH THIS COMPLEX. MM5...WRF AND HPC FORECASTS SIGNIFICANTLY LESS...FORECASTING GENERALLY THREE QUARTERS TO AN INCH OF WIDESPREAD RAINFALL. GIVEN RELATIVE DRY SOIL CONDITIONS...DO NOT THINK A FLASH FLOOD WATCH IS WARRANTED...BUT DAY SHIFT MAY WANT TO TAKE ANOTHER LOOK AT THIS LATER TODAY. BACK IN NORTHWEST FLOW FOR WEDNESDAY AS FRONT SHIFTS TO THE SOUTH AND EAST. TEMPERATURES SHOULD REMAIN COOL AS SURFACE WINDS WILL BE OUT OF THE NORTHEAST AND EAST THROUGH THURSDAY. GULF MOISTURE BEGINS TO RETURN THURSDAY AS SURFACE HIGH PUSHES OFF TO THE EAST AND WINDS BECOME MORE SOUTHERLY. CLAYCOMB && .AVIATION... FOR THE 18Z SGF/JLN/BBG TAFS...WILL KEEP AT LEAST VICINITY STORMS THROUGH THE AFTERNOON AS MOISTURE OVERRIDES AN OUTFLOW BOUNDARY EXTENDING ROUGHLY FROM NEOSHO TO BRANSON.
