NATIONAL WEATHER SERVICE WICHITA KS
350 PM CDT MON MAY 26 1997

SHORT TERM:
SATELLITE SHOWING UPPER LEVEL SHORTWAVE KICKING OUT INTO WESTERN KS
LATE THIS AFTN. TSRA ALREADY DEVELOPING ACROSS WRN KS AND THESE
STORMS WILL CONTINUE TO MOVE EAST OVERNIGHT.  A FEW -RA ALREADY
FALLING OVER CENTRAL KS...BUT WILL LIKELY SEE THE STORMS OUT WEST
MOVE IN LATER TONIGHT...AND FLASH FLOOD GUIDANCE NUMBERS ARE RUNNING
A LITTLE LOW DUE TO RAINS FROM THE LAST FEW DAYS.  SOUTH CENTRAL AND
MORE INTO SE KS IS JUST WAITING FOR A KICKER TO GET THINGS GOING.
LI'S NR -6 AND CAPES IN THE 2500 J/KG AND WITH RIGHT REAR OF THE
UPPER LEVEL JET MOVING THROUGH THIS EVENING...SHOULD HELP GET THINGS
GOING. AGAIN FFG NUMBERS RUNNING LOW IN SE KS SO WILL GO WITH A
FLASH FLOOD WATCH TONIGHT FOR CENTRAL AND SE KS.

LONG TERM:
LOW SHIFTS OFF TO THE EAST AND SFC WINDS BECOME NORTH ACROSS THE
ENTIRE REGION...BRINGING IN MUCH COOLER AIR.  WRAP-AROUND MOISTURE
MAY STILL LINGER ACROSS MAINLY CENTRAL AND SE SECTIONS IN THE
MORNING. HOWEVER THROUGH THE ENTIRE PERIOD AS SEVERAL SHORT WAVES
SLIDE THROUGH THE MEAN FLOW...COULD SEE A FEW SHOWERS JUST ABOUT
ANYWHERE.  HOWEVER IT APPEARS THAT THE BEST CHANCE WILL BE TUESDAY
NIGHT WHEN WINDS BEGIN TO TURN BACK AROUND TO THE EAST AND SE INTO A
NW FLOW ALOFT. BEST CHANCE WILL BE ALONG THE KS/CO BORDER BUT COULD
SEE A FEW DRIFT INTO THE CWA DURING THE OVERNIGHT HOURS.

LEANED TOWARDS THE ETA/AVN SOLUTIONS...NGM SEEMED A LITTLE TO FAR
NORTH WITH FEATURES...AND FWC TEMPS LOOKED A LITTLE TO WARM SO WENT
THE COOLER NUMBERS.
