AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE KANSAS CITY/PLEASANT HILL MO 336 AM CDT SAT MAY 11 2002 MAIN FORECAST CONCERN IS WITH PRECIPITATION THIS MORNING AND AGAIN TONIGHT. WILL LEAN TOWARD ETA SOLUTION...THOUGH HOPE ITS QPF FIELDS FOR TONIGHT ARE OVERDONE...SINCE IT IS SHOWING IN EXCESS OF 2 INCHES...WITH 06Z MESO ETA EVEN HIGHER. THIS MORNING...WARM FRONT LIFTING THROUGH AREA. THETA E ADVECTION OVER TOP OF THIS BOUNDARY HAS SET OFF THUNDERSTORMS PRODUCING VERY HEAVY RAIN. FORTUNATELY...THESE WILL BE LIFTING NORTH THIS MORNING AS WARM FRONT LIFTS NORTH INTO IOWA. CWA WILL BE IN WARM SECTOR TODAY...WITH PLENTY OF MOISTURE BEING PUMPED NORTHWARD. SURFACE DEWPOINTS BY AFTERNOON SHOULD BE IN THE 60S...AND PRECIPITABLE WATER BY EVENING IN EXCESS OF AN INCH AN A HALF IN THE FORECAST AREA. THIS WILL SET THE STAGE FOR VERY HEAVY RAINFALL TONIGHT AS COLD FRONT MOVES INTO AREA AT THE SAME TIME A WEAKER UPPER LEVEL WAVE MOVES THROUGH. THIS SHOULD LEAD TO MCS DEVELOPMENT. OUTFLOW FROM THIS CONVECTION OVERNIGHT SHOULD HELP PUSH FRONT TO JUST SOUTH OF FORECAST AREA BY SUNDAY MORNING. STRONGER SHORT WAVE THEN APPROACHES. PREFER THE MORE SOUTHERN TRACK OF THE ETA VORT MAX...GIVEN THE INFLUENCE OF A NORTHERN STREAM SHORT WAVE. THUS THINK FOR SUNDAY/SUNDAY NIGHT TIMEFRAME...THE HEAVIER RAIN SHOULD STAY SOUTH OF FORECAST AREA. WILL GO WITH A FLOOD WATCH FOR TONIGHT. GROUND ALREADY PRETTY SATURATED THROUGHOUT FORECAST AREA...ESPECIALLY AREAS SOUTH OF MISSOURI RIVER...SO EVEN IF SOUTHERN PART OF CWA DOES NOT GET EXTREMELY HEAVY RAIN...EVEN MODERATE RAIN MAY CAUSE PROBLEMS.
