AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE KANSAS CITY/PLEASANT HILL MO
240 AM CDT WED APR 11 2001

FORECAST FULL OF CHALLENGES AGAIN.  MAIN CONCERNS WOULD PROBABLY BE
TIMING/STRENGTH OF TSRA...WINDS TODAY...AND FLOOD POTENTIAL.
IMPRESSIVE LOOKING BOW (REFERENCE G76 IN CNK OB) MOVING ALONG KS/NE
BORDER...SO WILL KEEP THIS A LITTLE SHORTER THAN USUAL.

FORECAST SOUNDINGS FOR FIRST BATCH OF CONVECTION NOT ALL THAT
UNSTABLE...MORE OR LESS MOIST ADIABATIC.  BUT WITH WINDS
STRENGTHENING AT ALL LEVELS...WILL GO AHEAD AND MAINTAIN MENTION OF
SVR FOR ALL ZONES.  HAVE A HUNCH FAR WRN ZONES WILL JUST SEE THE ONE
BATCH OF TSRA EARLY...BUT WILL GO AHEAD AND INCLUDE POP FOR PSBL
EARLY AFTN REDEVELOPMENT ALONG DRYLINE.  SPEED OF MOVEMENT OF STORMS
SHOULD KEEP RAINFALL AMTS FROM BECOMING TOO EXCESSIVE...BUT WITH
ANTECEDENT RAINFALL QUITE HIGH...GROUND COMPLETELY SATURATED AND
SOME FFG VALUES BELOW 1...MUST EXTEND FF WATCH INTO THIS MORNING.

CONVERGENCE ALONG DRYLINE FOR AFTN REDEVELOPMENT NOT TERRRIBLY
IMPRESSIVE...BUT WITH STG UPPER DYNAMICS COMING OUT AND BASICALLY
UNCAPPED ATMOSPHERE...SHOULD SEE NEXT ROUND FIRE THIS AFTERNOON.
ERN ZONES SEEM PRETTY GOOD BET...WRN ZONES WILL PROBABLY GO WITH
CHC.  IMPRESSIVE WIND FIELDS AND STILL GOOD INSTBY REQUIRE MENTION
OF SVR FOR AFTN FOR ERN ZONES...UNCERTAIN ABOUT WRN ZONES.

WILL GO AHEAD AND RUN WIND ADVY FOR ALL ZONES TODAY.  FIRST THOUGHT
WAS TO LIMIT IT TO AFTN FOR STG SUBSIDENT FLOW BEHIND DRYLINE.
HOWEVER...WATCHING OBS OVER KS AND OK SUGGESTS THAT ADVY CRITERIA
MAY BE REACHED AHEAD OF CONVECTION THIS MORNING.

MAV GUIDANCE PRETTY CLOSE AND WONT BE TOO FAR AWAY FROM IT
THROUGHOUT.

.EAX...
FLASH FLOOD WATCH ALL ZONES THIS MORNING
WIND ADVISORY ALL ZONES TODAY
