AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE KANSAS CITY/PLEASANT HILL MO 357 PM CDT SAT MAY 11 2002 MAIN FCST CONCERN AT THIS TIME IS PRECIP INTENSITY TONIGHT THROUGH SUNDAY. CLEARING AHEAD OF SFC FRONT LOCATED ACROSS CENTRAL KANSAS...HAS ALLOWED TEMPS TO REACH INTO THE 80S ACROSS THAT AREA...LEADING TO RAPID DESTABOLIZATION AND STRONG TO SEVERE TSRA. CLOUDS HAVE BEEN SLOW TO DISSIPATE DUE TO HIGH THETA-E AIR OVER MY FCST AREA...HOLDING TEMPS DOWN SOME. HOWEVER ANY BREAK IN THE CLOUDS HAS ALLOWED RAPID WARMING. SEVERAL PIECES OF ENERGY HAVE BEEN MOVING ACROSS THE REGION TODAY...CONTINUING TO PRODUCE SCATTERED TSRA ACROSS NORTHERN MO. A MORE SIGNIFICANT VORT LOBE IS EXPECTED TO MOVE ACROSS THE REGION TONIGHT. UPPER LEVEL DIFFLUENCE INCREASES OVERNIGHT AS WELL. SFC FRONT DOESNT MAKE IT TO MO UNTIL LATE THIS EVENING. DONT EXPECT IT TO MOVE THROUGH CEN MO UNTIL SUN MORNING. SFC BASED LI/S ARE IN THE -2 TO -4 RANGE. SFC BASED CAPES ARE GENERALLY 1000-2000J/KG. EXPECT CURRENT TSRA OVER EXTREME EAST CEN KS/WEST CEN MO TO NOT REACH SEVERE LEVELS DUE TO SOMEWHAT LIMITED HEATING. HOWEVER EXPECT SEVERE POTENTIAL TO INCREASE AS FRONT APPROACHES. WITH THE EXCEPTION OF ALONG THE SFC FRONT...EXPECT MAINLY HIGH WINDS AND HAIL. HEAVY RAIN IS ALSO EXPECTED. PRECIPITABLE WATER IS AROUND 1.25-1.5. WITH MAIN UPPER LOW NOT MOVING ACROSS UNTIL SUN NIGHT...FRONT SHOULD SLOW OR STALL OVER CEN MO. WILL EXTEND FLOOD WATCH UNTIL NOON SUNDAY. PRECIP SHOULD BE TAPERING OFF BY LATE AFTERNOON/EVENING SUNDAY. MODELS CONTINUE TO INDICATED NEXT CHC OF RAIN WILL BE THURSDAY PROBABLY LATE...CONTINUING UNTIL SATURDAY. SHOULD SEE A GOOD WARMUP BY WED. EXPECT SOME MODERATION IN TEMPS THU-SAT WITH ABUNDANT CLOUD COVER AND SCATTERED TSRA IN AREA. NRR 336 AM... 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. THANKS TO SURROUNDING OFFICES FOR COORDINATION. NOT MUCH CHANGES TO LONGER RANGE PERIODS. LOOKS DRY THROUGH AT LEAST MID WEEK AS RIDGING BUILDS IN. PC .EAX...
