AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE WICHITA KS
602 PM CDT SAT APR 21 2001

...MESOSCALE UPDATE...

MAIN FOCUS FOR TSTMS OVR NEXT FEW HRS WL BE ALG WFNT CURRENTLY
EXTENDING FM NR SLN TO JUST S OF RSL.  THE FNT CONTS TO MOVE TO THE
N.  MOST IMPORTANTLY THE HILLSBORO PROFILER/RASS SOUNDING SHOWS STG
CAP.  THIS IS CONSISTANT WITH BOTH LAPS SOUNDINGS.  RADAR TRENDS
ALSO SIMILAR WITH WEAK DVLPMT ALG FNT IN CNTRL KS BUT WITH
MOST/STONGEST TSTMS TO THE NE WHERE CAP IS WEAKER.  WHILE CANNOT RUN
OUT AN ISOLATED/BRIEF STG/SVR TSTM IN CNTRL KS THRU SUNSET...BELIEVE
BETTER CHC WL BE LATER TONIGHT AS LLVL JET KICKS IN AND SOME COOLING
ALF.  HOWEVER THE BIG QUESTION THEN IS WHERE WL THE FNT BE LOCATED?
IF 12Z MODELS ARE CORRECT MUCH OF ACTIVITY WL END UP N OF OUR FCST
AREA.  THE ONLY OTHER CHC WOULD BE IF TSTMS DVLP ALG RETREATING
DRYLN TO THE W AND THEN MOVE INTO THE AREA...BUT AGAIN THAT WOULD
LKLY BE MUCH LATER TNGT.
