Area forecast discussion, Jun 23, 3:00 AM CDT, 24 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE KANSAS CITY/PLEASANT HILL MO 300 AM CDT TUE JUN 23 1998 ROUND FIVE...AND 2ND NIGHT IN A ROW FOR MULTIPLE MCSS UPSTREAM OF CWA. THIS FCST PROBABLY THE TRICKIEST. MAIN TWO PROBLEMS ARE NEED FOR FF WATCH AND POPS TONIGHT. TOUGH CALL ON THE FFA. FFG VALUES VERY LOW OVER SRN HALF OF CWA WHERE 1-3 FELL 24 HOURS AGO. NRN COUNTIES CAN TAKE A BIT MORE...THOUGH NOT THAT MUCH. ETA WOULD SUGGEST (THOUGH IT COMPLETELY MISSED THE CURRENT ERN KS ACTIVITY) THAT 850 JET WILL VEER SLIGHTLY DURING MORNING AND STRENGTHEN. POSITIONING OF JET WOULD SUGGEST THAT SWRN NEB ACTIVITY WOULD ROLL EWD ALONG KS/NEB BORDER SO WE MAY VERY WELL GET TWO ROUNDS AGAIN PRIOR TO 18Z. BASED ON THIS...WILL GO AHEAD AND ISSUE FFA FOR THIS AM. NERN COUNTIES CERTAINLY THE WEAKEST ARGUMENT FOR FFA...BUT FOR SIMPLICITYS SAKE WILL PROBABLY INCLUDE THEM AS WELL. MODELS ALL DO COMPLETELY DIFFERENT THINGS WITH OUR EVER-SO CRITICAL BOUNDARY. WITH WRN GT LAKES SFC HIGH RETREATING EWD...FRONT SHD HAVE EASIER TIME WORKING NORTH. IF WE ARE ABLE TO CLEAR OUT TODAY...BOUNDARY SHOULD HAVE EASY TIME MOVING NORTH OF CWA. IF NOT...TONIGHTS LLJ (WHICH SHOULD BE FOCUSED WELL NORTH) WILL ONCE AGAIN IMPINGE ON BOUNDARY AND WE COULD DO IT ALL OVER AGAIN. HOWEVER...THINK WARMING TEMPS AT 700 MB SHOULD LARGELY PRECLUDE TSRA DEVELOPMENT. WILL PROBABLY LEAVE FCST DRY TONIGHT ALTHOUGH MAY INCLUDE LOW CHC POPS IN NW COUNTIES WHERE THEY STAND THE BEST CHC. GUIDANCE TEMPS TODAY ACCEPTED AS TIMING OF CLEARING WILL MEAN EVERYTHING. WILL GO WITH WARMER FAN IN PERIODS 2-4. .EAX... MO...FLASH FLOOD WATCH ALL ZONES THIS MORNING KS...FLASH FLOOD WATCH ALL ZONES THIS MORNING JM
