   NWS STORM PREDICTION CENTER NORMAN OK
   225 PM CDT TUE MAY 28 2013

   THE NWS STORM PREDICTION CENTER HAS ISSUED A

   * TORNADO WATCH FOR PORTIONS OF 
     SOUTHERN IOWA
     NORTHEAST KANSAS
     NORTHERN MISSOURI
     FAR SOUTHEAST NEBRASKA

   * EFFECTIVE THIS TUESDAY AFTERNOON AND EVENING FROM 225 PM UNTIL
     1000 PM CDT.

   * PRIMARY THREATS INCLUDE...
     SEVERAL TORNADOES POSSIBLE
     SEVERAL VERY LARGE HAIL EVENTS TO 3 INCHES IN DIAMETER LIKELY
     SEVERAL DAMAGING WIND GUSTS TO 70 MPH POSSIBLE

   THE TORNADO WATCH AREA IS APPROXIMATELY ALONG AND 80 STATUTE
   MILES NORTH AND SOUTH OF A LINE FROM 25 MILES SOUTH SOUTHWEST OF
   CONCORDIA KANSAS TO 60 MILES EAST OF KIRKSVILLE MISSOURI.  FOR A
   COMPLETE DEPICTION OF THE WATCH SEE THE ASSOCIATED WATCH OUTLINE
   UPDATE (WOUS64 KWNS WOU3).

   PRECAUTIONARY/PREPAREDNESS ACTIONS...

   REMEMBER...A TORNADO WATCH MEANS CONDITIONS ARE FAVORABLE FOR
   TORNADOES AND 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.

   &&

   DISCUSSION...TSTMS ARE EXPECTED TO INCREASE IN COVERAGE AND
   INTENSITY THIS AFTERNOON ALONG SYNOPTIC FRONT EXTENDING FROM LOW
   PRESSURE OVER CNTRL KS NEWD ACROSS SRN IA.  OTHER STORMS ONGOING
   ALONG AN OUTFLOW BOUNDARY LIFTING NWD THROUGH THE I-70 CORRIDOR OF
   MO SHOULD STRENGTHEN AS WELL.  GIVEN THE COMBINATION OF STRONG
   INSTABILITY AND 40-50 KT OF DEEP-LAYER SHEAR THE POTENTIAL WILL
   EXIST FOR INTENSE SUPERCELLS CAPABLE OF VERY LARGE HAIL AND DAMAGING
   WINDS.  GIVEN THE MODEST LOW-LEVEL SHEAR...TORNADO POTENTIAL WILL BE
   MODULATED BY MATURE STORMS INTERACTING WITH THE SYNOPTIC FRONT AND
   OUTFLOW BOUNDARY WHERE VORTICITY IS ENHANCED.

   AVIATION...TORNADOES AND A FEW SEVERE THUNDERSTORMS WITH HAIL
   SURFACE AND ALOFT TO 3 INCHES. EXTREME TURBULENCE AND SURFACE
   WIND GUSTS TO 60 KNOTS. A FEW CUMULONIMBI WITH MAXIMUM TOPS TO
   550. MEAN STORM MOTION VECTOR 26025.
