NORTHWEST MISSOURI FORECAST DISCUSSION NATIONAL WEATHER SERVICE PLEASANT HILL/KANSAS CITY MO 329 AM CDT FRI MAY 10 1996 MAIN FCST CHALLENGES INCLUDE RW/TRW COVERAGE AND INTENSITY AND RELATED QPF CONCERNS. CONVECTION THAT TRIED TO DVLP AROUND 04Z IN XTRM NERN KS GIVES AN IDEA OF WHAT TYPE OF ATMOS WE ARE DEALING WITH. CELLS WENT UP INITIALLY BUT HAD TROUBLE SURVIVING 100 J/KG CIN AND +12 700 MB TEMPS BASED OFF 00Z TOP SNDG. 00Z ETA INITIALIZED 700 MB TEMPS WERE ENTIRELY TOO COOL...BY AS MUCH AS 4 DEG. THIS MAKES PARTS OF ETA FCST DIFFICULT TO ACCEPT. UNFORTUNATELY...HAD TROUBLE RETRIEVING NGM AND AVN SO HAVE LITTLE ELSE TO GO ON. AT ANY RATE...IT'S GOING TO TAKE SOME DYNAMIC COOLING OF MID LEVEL TEMPS AND/OR FRONTAL LIFT TO REALLY GET THINGS GOING. LO AND BEHOLD...NATURE GIVES A FAIRLY STG SFC FRONT. CURRENT 88D LOOP SHOWS RW/TRW DVLPG OVER NE KS ALG/JUST BEHIND SFC FRONT OR OUTFLOW BNDRY LOCATED FM P35 TO JUST N OF MCI TO NR TOP. BNDRY WAS ON THE MOVE EARLIER TNGT BUT HAS SINCE SLOWED AND CONVECTION NOW BEGINNING TO FIRE ALG IT. WUD XPCT THIS TREND TO CONTINUE WITH EVENT TURNING INTO MORE OF A RAIN EVENT THAN SVR THRT. SOME DISCUSSION AROUND HERE AS TO NEED FOR CONTINUING FLASH FLOOD WATCH. FOCUS FOR HVST R SHD BE A BIT SOUTH OF CWA...BUT WITH VERY LOW FFG VALUES...INITIALLY HIGH PW'S AND FRONTAL/SYNOPTIC SCALE LIFTING THROUGH AT LEAST 18Z WILL OPT TO KEEP WATCH GOING FOR TODAY. DAY SHIFT MAY HAVE TO TRIM BACK WATCH...ESPCLY IN NW...BUT HATE TO CANCEL WHOLE THING WITH EXPECTED RW/TRW. RW/TRW TO FINALLY SHUT OFF EARLY THIS EVE AFT PASSAGE OF UPPER WAVE. CONSIDERABLY COLDER AIR ON THE WAY BHND FRONT SO HIGHS TO OCCUR THIS AM...WITH FALLING TEMPS THROUGH@OUT MUCH OF DAY. MCI 074/044 82 JM
