330 PM CDT SAT MAY 17 1997

...SHORT TERM...
OBVIOUS CONCERN IN SHORT TERM IS CHC FOR TSRA. 18Z SFC MAP INDICATES
AN E-W BOUNDARY FROM NW TO NC KANSAS...WITH N-S TROF ACROSS WESTERN
KANSAS. VERY JUICY AIR IN PLACE WITH DWPTS INTO THE MID 60S IN SC/SE
ZONES. ONLY THING LACKING IS A TRIGGER...AND WATER VAPOR SAT
PIX/PROFILERS DO SHOW A WEAK SHORTWAVE ACROSS W NE/W KANSAS WHICH
MODELS AGREE ON SHIFTING EAST ACROSS NC/NE KANSAS THIS EVENING. ETA
IS A TOUCH SLOW WITH THIS FEATURE. THIS SHORTWAVE SHOULD BE ENOUGH
TO ELIMINATE CAP AND TRIGGER SCT TSRA IN CENTRAL KANSAS.  LOW LEVEL
BOUNDARIES/UPPER SUPPORT REMAIN NORTH OF SC/SE ZONES...BUT WITH LOBE
OF UPPER VORT PASSING THROUGH SC KANSAS WILL LEAVE MENTION OF SCT
TSRA HERE. IN SE KANSAS...HOWEVER...ANY VORT LOBE THAT PASSES
THROUGH HERE WILL BE WELL AFTER SUNSET...THUS WILL LEAVE DRY
FORECAST IN PLACE HERE.

WILL HAVE TO KEEP CLOSE WATCH ON TSRA DEVELOPMENT IN CNTRL/SC KANSAS
AS ADAP INDICATES LI/S FROM -8 TO -10 AND MODIFIED SOUNDINGS SHOW
CAPES APPROACHING 4000 J/KG. WITH WBZ VALUES BLO 9000 FT...LARGE
HAIL APPEARS TO BE THE BIGGEST SVR THREAT. AS FOR TEMPS...LOW LEVEL
MOISTURE AXIS REMAINS IN PLACE AND WITH TIGHTENING PRES GRADIENT
A WARM AND MUGGY NIGHT IS ON TAP AND WARMER FWC NUMBERS WILL BE THE
WAY TO GO.

HAZARDOUS WEATHER OUTLOOK
NATIONAL WEATHER SERVICE WICHITA KANSAS
1102 AM CDT SAT MAY 17 1997

THIS OUTLOOK PERTAINS TO THE FOLLOWING COUNTIES IN CENTRAL KANSAS:
BARTON      COWLEY      HARVEY      MARION      RENO     SEDGWICK
ELLSWORTH   KINGMAN     MCPHERSON   RUSSELL     SUMNER   CHASE
HARPER      LINCOLN     RICE        SALINE      BUTLER

AND IN SOUTHEAST KANSAS:
ALLEN       ELK         LABETTE     NEOSHO      WOODSON
CHAUTAUQUA  GREENWOOD   MONTGOMERY  WILSON

SYNOPSIS:

MOSTLY SUNNY SKIES TODAY WILL HELP PUSH TEMPERATURES WELL INTO THE
80S WITH SOME ISOLATED 90 DEGREES READINGS LIKELY IN CENTRAL AND
SOUTH CENTRAL KANSAS. MEANWHILE...SOUTHERLY WINDS HAVE USHERED IN
MOIST AIR INTO THE REGION WITH DEW POINT TEMPERATURES REACHING INTO
THE LOWER 60S. AS A RESULT...AN UNSTABLE AIR MASS EXISTS OVER THE
AREA.

LATE THIS MORNING...A TROUGH OF LOW PRESSURE WAS LOCATED ACROSS
CENTRAL KANSAS. ALTHOUGH THIS TROUGH IS EXPECTED TO WEAKEN...IT
STILL COULD ACT AS A FOCAL POINT FOR THUNDERSTORM DEVELOPMENT. ALSO
...AN UPPER LEVEL AREA OF LOW PRESSURE ACROSS THE WESTERN HIGH
PLAINS WILL PUSH EAST INTO CENTRAL KANSAS BY THIS EVENING. ALL OF
THESE FACTORS WILL HELP BRING THE CHANCE FOR SCATTERED
THUNDERSTORMS DEVELOPING LATE THIS AFTERNOON ACROSS CENTRAL AND
SOUTH CENTRAL KANSAS. THE STORMS WILL THEN MOVE SOUTHEAST THROUGH
THE EVENING.

A FEW OF THESE STORMS COULD PRODUCE LARGE HAIL AND DAMAGING WINDS.
THE GREATEST THREAT FOR SEVERE WEATHER WILL BE ALONG AND NORTH OF
INTERSTATE 70. SPOTTER ACTIVATION MAY BE REQUIRED ACROSS CENTRAL AND
SOUTH CENTRAL KANSAS LATE THIS AFTERNOON INTO THIS EVENING.

THOSE PLANNING ANY OUTDOOR ACTIVITIES THIS EVENING WILL WANT TO KEEP
TUNED TO NOAA WEATHER RADIO OR YOUR LOCAL MEDIA FOR ADDITIONAL
INFORMATION.
