Area forecast discussion, Jun 12, 2:41 PM CDT, 8 hours 14 minutes before
NORTHWEST MISSOURI FORECAST DISCUSSION NATIONAL WEATHER SERVICE PLEASANT HILL/KANSAS CITY MO 241 PM CDT THU JUN 12 1997 CONVECTIVE POTENTIAL CONTINUES TO BE MAIN FORECAST PROBLEM THROUGH PERIOD. VISIBLE SATELLITE IMAGERY AND SURFACE ANALYSIS SHOWS SURFACE BOUNDARY FROM NORTHERN MO BACK INTO CENTRAL KS THIS AFTERNOON. PLENTY OF LOW-LEVEL MOISTURE AVAILABLE...HOWEVER VERY LITTLE UPPER LEVEL SUPPORT TO AID IN THE DEVELOPMENT OF CONVECTION OVER OUR FORECAST AREA. IN ANY CASE...FEEL THAT DIURNAL HEATING COMBINED WITH BOUNDARY SHOULD BE SUFFICIENT TO PRODUCE SOME SCATTERED SHOWERS AND THUNDERSTORMS LATE THIS AFTERNOON INTO THIS EVENING...ESPECIALLY SOUTH OF THE BOUNDARY. MODELS ALL SEEM TO BE HINTING AT MORE ORGANIZED CONVECTION DEVELOPING OUT OVER SOUTH CENTRAL KS/NORTH CENTRAL OK. FAVORED TRACK WOULD TAKE RESULTING MCS INTO SOUTHWEST MO AND NORTHWEST AR OVERNIGHT. MCS SHOULD PUSH BOUNDARY FURTHER SOUTH DURING OVERNIGHT AND TOMORROW...HOWEVER BACK DOOR BOUNDARY APPROACHES FORECAST AREA FROM NORTH. BEST MOISTURE CONVERGENCE AND LEFTOVER CONVECTION WILL BE WELL TO THE SOUTH OF FORECAST AREA AND WILL LIKELY ROB ANY AVAILABLE ENERGY FOR CONVECTIVE DEVELOPMENT OVER OUR FORECAST AREA. HOWEVER...WITH DAYTIME HEATING AND BOUNDARY IN AREA LATE TOMORROW AFTERNOON WILL KEEP CHANCE POPS IN FOR FRIDAY. BOUNDARY PUSHING INTO NORTHERN MISSOURI TOMORROW WASHES OUT BY SATURDAY AND MAIN FOCUS FOR CONVECTION SHOULD REMAIN WELL SOUTH OF THE FORECAST AREA. WILL GO A LITTLE ABOVE FWC/FAN GUIDANCE TEMPERATURES FOR HIGHS...BUT LOWS LOOK TO BE IN BALLPARK. .EAX...NONE. MJM
