Area forecast discussion, Jun 22, 3:00 AM CDT, 2 hours 57 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE KANSAS CITY/PLEASANT HILL MO
300 AM CDT MON JUN 22 1998

THINK THIS IS THE 4TH NIGHT IN A ROW FOR MCS MOVING THRU AREA.
FIRST CONCERN IS NEED FOR FF WATCH.  CURRENT TSRA ACTIVITY ALREADY
HAS GENERATED SEVERAL AREAS OF 1.  NEXT BATCH OF TSRA OVER CNTRL KS
APPEARS TO BE HEADED STRAIGHT FOR CWA.  LOOKING AT 850 MB WINDS OFF
PROFILERS AND FORECAST OF SUCH FROM ETA WOULD SUGGEST ACTIVITY
SHOULD CONTINUE EASTWARD AND PERSIST AT LEAST THROUGH LATE MORNING.
700 MB WAA PATTERN THROUGH 00Z TONIGHT LOOKS SUSPICIOUSLY SIMILAR TO
OTHER DAY WHEN MCS WOULDNT QUIT OVER CENTRAL MO.  SO...GIVEN
ANTECEDENT RAINFALL AND MOST OF CWA WITH FF GUIDANCE VALUES UNDER AN
INCH (MANY AROUND 0.5)...WILL HAVE TO GO WITH FFA.  NRN MO LOOKS
LIKE WILL ESCAPE THE HEAVIEST RAIN AND SINCE THIS MATCHES THE
CURRENT SVR TSTM WATCH WELL WILL CARRY FFA IN SAME AREA.  WILL CARRY
WATCH ALL DAY LONG...GIVEN POSSIBILITY OF CONTINUED REDEVELOPMENT.
DAY SHIFT MAY HAVE TO CANCEL EARLY IF THIS SCENARIO DOESNT PAN OUT.

ETA SHOWS SFC BOUNDARY MOVING NWD BY TONIGHT.  GOOD UPSLOPE ON HI
PLAINS SHD DEVELOP ANOTHER MCS TONIGHT...WHICH SHOULD FOLLOW
BOUNDARY INTO NRN MO TONIGHT.  GOOD 50+ KT LLJ TO FEED STORMS SO MAY
BE ONE MORE BUSY NIGHT.  SURPRISED TO SEE NO SLGT RISK THERE.  WILL
CARRY HIEST POPS TONIGHT UP THERE...LESSER DOWN SOUTH.

WILL CONTINUE PREVIOUS SHIFTS CHC POPS FOR TUE GIVEN POSSIBILITY OF
MON NIGHTS MCS LINGERING INTO DAYTIME...BUT AFTER THAT IT APPEARS
CAP SETS IN.

WILL UNDERCUT TEMP GUIDANCE TODAY...AFTER THAT GENERALLY WILL FOLLOW.

.EAX...
