AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE SPRINGFIELD MO 650 AM CDT WED SEP 1 2010 .DISCUSSION... MAIN FOCUS WILL BE WITH CONVECTIVE PRECIPITATION CHANCES THROUGH THURSDAY NIGHT AND TEMPERATURES BEHIND THE FRONT FRIDAY INTO THE WEEKEND. CONVECTIVE COMPLEX DEVELOPED DURING THE EVENING ACROSS NORTHERN MISSOURI AND THIS HAS TRACKED EAST/SOUTHEAST INTO FAR NORTHERN SECTIONS OF THE CWA EXTENDING NORTHWARD INTO NORTHEAST MISSOURI EARLY THIS MORNING. OUTFLOW HAD OUTRUN THE MAIN AREA OF CONVECTION EARLIER BUT HELPED TO INITIATE ADDITIONAL CONVECTION BETWEEN 11 PM AND MIDNIGHT. A NEW OUTFLOW HAS STARTED TO PUSH SOUTH OF THE MAIN AREA OF CONVECTION BUT SHOULD MOVE INTO A LESS FAVORABLE AREA FURTHER SOUTH FOR MORE DEVELOPMENT WITH LESS INSTABILITY AND UPPER DIVERGENT SUPPORT. OUR NORTHERN CWA WILL STILL BE UNDER THE GUN FOR CONVECTION AND HEAVY RAINFALL THROUGH THE REMAINDER OF THE NIGHT BUT POPS SHOULD DIMINISH QUICKLY FURTHER TO THE SOUTH AND HAVE ADJUSTED REMAINDER OF OVERNIGHT PERIOD TO ACCOUNT FOR THIS. ALL MODELS STILL BRING REMNANTS OF MCS THROUGH THE AREA TODAY WITH ADDITIONAL DEVELOPMENT ALONG ANY REMNANT BOUNDARIES AND UPPER LEVEL SHORTWAVE ENERGY. WILL BE GOING WITH 60 TO 70 POPS ACROSS ALL BUT SOUTHEAST CWA TO ACCOUNT FOR THIS TODAY. MAY SEE A LITTLE BREAK IN THE PRECIPITATION CHANCES WEDNESDAY NIGHT BUT CANNOT RULE THEM OUT COMPLETELY...ESPECIALLY DURING THE EVENING. MAIN FRONTAL PASSAGE WILL NOT ARRIVE UNTIL THURSDAY/THURSDAY NIGHT TIME FRAME ACROSS THE CWA. PRECIPITATION CHANCES WILL INCREASE AGAIN WITH THE FRONTAL PASSAGE WITH MUCH COOLER/DRIER AIR MASS MOVING IN BEHIND THE FRONT AND ENDING PRECIPITATION CHANCES FROM NORTHWEST TO SOUTHEAST THURSDAY NIGHT. STRONG TO POSSIBLY SEVERE STORMS MAY DEVELOP ALONG THE FRONT IF ENOUGH INSTABILITY CAN DEVELOP DURING THE DAY. DRY CONDITIONS EXPECTED THROUGH THE WEEKEND BEHIND THE FRONT AS COOLER/DRIER AIR MASS MOVES INTO THE AREA. LINDENBERG && .AVIATION... PILOTS FLYING IN AND OUT OF THE SOUTHWEST MISSOURI AIRPORTS WILL NEED TO MONITOR WEATHER RADAR CLOSELY OVER THE NEXT 24 HOURS. SHOWERS AND THUNDERSTORMS WERE ONGOING THIS MORNING...AND WILL BE POSSIBLE THROUGH THURSDAY NIGHT. THIS ACTIVE WEATHER WILL OCCUR IN RESPONSE TO THE APPROACH OF A SLOW MOVING FRONTAL SYSTEM...THAT WILL INTERACT WITH INCREASING GULF MOISTURE. SHOWERS AND THUNDERSTORMS DIRECTLY OVER ONE OF THE AIRPORTS WILL LIKELY CAUSE IFR CONDITIONS...WITH LOWER VISIBILITIES BEING THE PRIMARY HAZARD. CEILINGS FALLING INTO THE MVFR CATEGORY WOULD BE ANOTHER HAZARD TO CONSIDER. CRAMER && .SGF WATCHES/WARNINGS/ADVISORIES... MO...NONE. KS...NONE. &&
