URGENT - IMMEDIATE BROADCAST REQUESTED
SEVERE THUNDERSTORM WATCH NUMBER 113
NWS STORM PREDICTION CENTER NORMAN OK
550 PM CDT WED MAR 28 2012

THE NWS STORM PREDICTION CENTER HAS ISSUED A
SEVERE THUNDERSTORM WATCH FOR PORTIONS OF

       NORTHEAST KANSAS
       WEST CENTRAL MISSOURI

EFFECTIVE THIS WEDNESDAY AFTERNOON FROM 550 PM UNTIL MIDNIGHT CDT.

HAIL TO 2 INCHES IN DIAMETER...THUNDERSTORM WIND GUSTS TO 70
MPH...AND DANGEROUS LIGHTNING ARE POSSIBLE IN THESE AREAS.

THE SEVERE THUNDERSTORM WATCH AREA IS APPROXIMATELY ALONG AND 45
STATUTE MILES NORTH AND SOUTH OF A LINE FROM 10 MILES WEST OF
CONCORDIA KANSAS TO 40 MILES EAST SOUTHEAST OF OLATHE KANSAS.
FOR A COMPLETE DEPICTION OF THE WATCH SEE THE ASSOCIATED WATCH
OUTLINE UPDATE (WOUS64 KWNS WOU3).

REMEMBER...A SEVERE THUNDERSTORM WATCH MEANS CONDITIONS ARE
FAVORABLE FOR SEVERE THUNDERSTORMS IN AND CLOSE TO THE WATCH
AREA. PERSONS IN THESE AREAS SHOULD BE ON THE LOOKOUT FOR
THREATENING WEATHER CONDITIONS AND LISTEN FOR LATER STATEMENTS
AND POSSIBLE WARNINGS. SEVERE THUNDERSTORMS CAN AND OCCASIONALLY
DO PRODUCE TORNADOES.

OTHER WATCH INFORMATION...CONTINUE...WW 112...

DISCUSSION...THUNDERSTORM DEVELOPMENT IS UNDERWAY ALONG A SURFACE
FRONT IN NE KS...WHERE THE INSTABILITY AXIS INTERSECTS THE BOUNDARY.
 MLCAPE NEAR 2500 J/KG AND EFFECTIVE BULK SHEAR OF 30-45 KT WILL
SUPPORT SOME SLOW-MOVING SUPERCELLS...THOUGH WEAKER FLOW ALOFT MAY
TEND TO LIMIT STORM LONGEVITY.  LIKEWISE...LOW-LEVEL SHEAR IS NOT
PARTICULARLY STRONG...THUS LARGE HAIL SHOULD BE THE PRIMARY SEVERE
THREAT FOR THE NEXT FEW HOURS.  LATER THIS EVENING...A GRADUAL
INCREASE IN STORM COVERAGE WITH WAA OVER THE BOUNDARY COULD PROMOTE
COLD POOL DEVELOPMENT AND SOME RISK FOR THE FORMATION OF A SMALL MCS
WITH AN ATTENDANT RISK FOR DAMAGING WINDS.

AVIATION...A FEW SEVERE THUNDERSTORMS WITH HAIL SURFACE AND ALOFT
TO 2 INCHES. EXTREME TURBULENCE AND SURFACE WIND GUSTS TO 60
KNOTS. A FEW CUMULONIMBI WITH MAXIMUM TOPS TO 500. MEAN STORM
