   THE NWS STORM PREDICTION CENTER HAS ISSUED A

   * SEVERE THUNDERSTORM WATCH FOR PORTIONS OF 
     NORTHWEST IOWA
     CENTRAL AND SOUTHWEST MINNESOTA
     EXTREME NORTHEAST NEBRASKA
     EXTREME SOUTHEAST SOUTH DAKOTA

   * EFFECTIVE THIS MONDAY AFTERNOON AND EVENING FROM 345 PM UNTIL
     1000 PM CDT.

   * PRIMARY THREATS INCLUDE...
     SCATTERED LARGE HAIL AND ISOLATED VERY LARGE HAIL EVENTS TO 2
       INCHES IN DIAMETER POSSIBLE
     SCATTERED DAMAGING WIND GUSTS TO 70 MPH POSSIBLE
     A TORNADO OR TWO POSSIBLE

   SUMMARY...THUNDERSTORM DEVELOPMENT IS EXPECTED IN THE NEXT COUPLE OF
   HOURS ALONG AND IN ADVANCE OF A COLD FRONT MOVING EASTWARD FROM
   SOUTH DAKOTA TOWARD MINNESOTA/NORTHWEST IOWA.  THE STORM ENVIRONMENT
   WILL FAVOR MOSTLY ORGANIZED CLUSTERS AND LINE SEGMENTS CAPABLE OF
   PRODUCING DAMAGING WINDS AND LARGE HAIL.  THERE WILL A SOMEWHAT
   GREATER SUPERCELL RISK...WITH PERHAPS A TORNADO OR TWO...ALONG A
   RESIDUAL BOUNDARY ACROSS SOUTHERN AND CENTRAL MINNESOTA.  THIS AREA
   WILL BE MONITORED CLOSELY THROUGH THE EVENING...IN CASE THE TORNADO
   RISK INCREASES TO THE POINT THAT A SMALL TORNADO WATCH BECOMES
   NECESSARY.

   THE SEVERE THUNDERSTORM WATCH AREA IS APPROXIMATELY ALONG AND 75
   STATUTE MILES EAST AND WEST OF A LINE FROM 10 MILES SOUTH OF
   SIOUX CITY IOWA TO 35 MILES NORTH NORTHEAST OF SAINT CLOUD
   MINNESOTA.  FOR A COMPLETE DEPICTION OF THE WATCH SEE THE
   ASSOCIATED WATCH OUTLINE UPDATE (WOUS64 KWNS WOU2).

   PRECAUTIONARY/PREPAREDNESS ACTIONS...

   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.
