AREA FORECAST DISCUSSION...CORRECTION TO WORDING NATIONAL WEATHER SERVICE PLEASANT HILL/KANSAS CITY MO 250 AM CDT WED JUN 25 1997 CONVECTION AND HEAVY RAIN POTENTIAL CONTINUES TO BE MAIN FORECAST CHALLENGES THROUGH PERIOD. SATELLITE AND RADAR TRENDS SHOW SHRA/TSRA ACTIVITY SLOWLY WEAKENING OVER NORTHWEST MO...HOWEVER NUMEROUS BOUNDARIES BEING LAYED OUT WHICH SHOULD HELP TO KEEP PRECIPITATION GOING THROUGH MUCH OF THE MORNING. WARM H7 TEMPERATURES OVER SOUTHERN AND CENTRAL PORTIONS OF THE FORECAST AREA HAVE EFFECTIVELY KEPT LID ON CONVECTION FOR MUCH OF THE OVERNIGHT...HOWEVER MODELS SHOW H7 THERMAL TROUGH ROTATING INTO AREA THIS MORNING...WHICH SHOULD ALLOW FOR SOME PRECIPITATION A BIT FURTHER SOUTH. MODELS IN DECENT AGREEMENT IN SAGGING FRONTAL BOUNDARY OVER SOUTHEAST NEBRASKA SLOWLY SOUTH THROUGH FORECAST AREA. CONVECTION THIS MORNING SHOULD HELP IN THIS PROCESS...ENDING THE THREAT FOR HEAVY RAINFALL OVER FAR NORTHWEST MO FOR THIS MORNING. COLD FRONT SHOULD LOSE PUSH ON SOUTHERN END AND BE ORIENTED MORE EAST-WEST BY THIS AFTERNOON. GENERALLY LIKE NGM SCENARIO WHICH BASICALLY WASHES OUT OR STALLS BOUNDARY ROUGHLY FROM JUST SOUTH OF MKC TO STL LINE. WITH H5 WAVE STILL PUSHING THROUGH...WOULD ANTICIPATE MORE CONVECTION TO FIRE THIS AFTERNOON IN VICINITY OF BOUNDARY. THIS PRECIPITATION WILL HAVE THE POTENTIAL FOR TRAINING FROM WEST TO EAST ALONG BOUNDARY. LIKE HPC EXCESSIVE RAINFALL OUTLOOK FOR TODAY AND TONIGHT WHICH HAS GREATEST THREAT FROM MKC EASTWARD TO STL. SURFACE HIGH SETTLES IN AS THIS AFTERNOON AND THIS EVENINGS CONVECTION PUSH WHAT IS LEFT OF BOUNDARY A BIT FURTHER SOUTH. SHOULD PROVIDE FOR A DRY DAY ON THURSDAY. WILL GENBERALLY LEAN TOWARDS WARMER FWC GUIDANCE THROUGH MOST OF THE PERIOD. .EAX...NONE. MJM
