MAIN CONCERN IN SHORT TERM IS CDFNT NOW ENTERING XTRM NWRN MO. GULF
MOIST HAS SURGED INTO CWA THIS AFTN WITH AFTN TEMPS REACHING
CONVECTIVE TEMPS AS PER AM SOUNDING. MSAS DATA INDICATES LIFTED
INDICES AROUND -8 ACR NWRN 1/2 CWA WITH CAPES LIKELY BETWEEN

SQUALL LINE WITH MCS DEVELOPMENT LATE THIS EVE AND TNGT. MAIN THREAT
DAMAGING WINDS...HOWEVER STEEP LAPSE RATES AND COOL MID LVL TEMPS
SUGGEST GOOD POTENTIAL FOR LARGE HAIL. GOOD AFTN PRES RISES IN ERN
NEB SUGGEST GOOD INITIAL PUSH OF FNT INTO CWA TNGT WITH SQUALL TO
PROGRESS SLOWLY SE WITH THE FNT.

OTHERWISE...PREFER AVN IN DEVELOPMENT OF UPR TROF IN ROCKIES WITH
AVN PREFERRED ON SPEED OF FNT. SQUALL LINE SHOULD HELP PUSH FNT INTO
XTRM SERN CWA BY DAYBREAK AS PER AVN.  AS A RESULT...BLV ETA/NGM
APPEARS TOO SLOW IN PUSH FNT ACR SRN CWA. HAVE LTL CONFIDENCE IN
TIMING AND LOCATION OF ANY SHRTWVS TO EJECT EAST OUT OF UPR
TROF...BUT DO XPCT PERIODIC WK SHRTWVS TO EJECT EAST INTO AREA.
IN ADDITION...AVN GRIDDS SUGGEST H8 FNT TO ONLY SAG TO A MKC TO IRK
LINE BY 00Z SUN WITH STG BAROCLINIC ZONE ACR CWA. ALTHOUGH UPR
DYNAMICS WK THROUGH PERIOD...ANY SHRTWV SHOULD TRIGGER PERIODS OF
RAIN AND A FEW THUNDERSTORMS IN STG BAROCLINIC ZONE  ...MAINLY ACR
SERN HALF OF CWA THROUGH SAT EVE. WK SYNOPTIC LIFT ALSO TO TRIGGER
PERIODS OF RAIN AND DRIZZLE SUNDAY AS UPR TROF APPROACHES.

HAZARDOUS WEATHER OUTLOOK
NATIONAL WEATHER SERVICE KANSAS CITY/PLEASANT HILL MO
100 PM CDT FRI SEP 22 2000

...SEVERE THUNDERSTORMS POSSIBLE MAINLY THIS EVENING...

FORECAST...THUNDERSTORMS WILL LIKELY DEVELOP BY LATE AFTERNOON
ACROSS NORTHWEST MISSOURI AND EXTREME NORTHEAST KANSAS.  THE
THUNDERSTORMS SHOULD FORM A COMPLEX OR A LINE AND MOVE SLOWLY
SOUTHEAST THROUGH THE EVENING AND OVERNIGHT HOURS.  LARGE HAIL AND
DAMAGING WINDS WILL BE POSSIBLE WITH THE STRONGEST STORMS.  LOCALLY
HEAVY RAINFALL MAY ALSO OCCUR.  SPOTTER ACTIVATION MAY BE REQUIRED
AFTER 5 PM.

DISCUSSION...A COLD FRONT EXTENDS FROM WESTERN IOWA INTO NORTH
CENTRAL KANSAS.  THIS FRONT WILL CONTINUE TO MOVE SOUTHEAST AND WILL
BE POSITIONED FROM SOUTHEAST KANSAS TO NORTHEAST MISSOURI BY SUNRISE
SATURDAY.  THIS FRONT WILL PROVIDE ENOUGH LIFT TO GENERATE
THUNDERSTORMS BY LATE THIS AFTERNOON.  THE ATMOSPHERE BY LATE THIS
AFTERNOON WILL BE UNSTABLE SINCE LOW LEVEL MOISTURE HAS RETURNED TO
THE AREA.  ENOUGH WIND SHEAR AND INSTABILITY SHOULD BE PRESENT FOR
SOME OF THE THUNDERSTORMS TO REACH 	SEVERE LEVELS.
