   ORGANIZATION IS PARTLY ASSOCIATED WITH A WELL-DEVELOPED MCV IN THE
   TRAILING STRATIFORM REGION NEAR THE KEYA PAHA COUNTY NEB/TRIPP
   COUNTY SD BORDER.  AS THE COLD POOL CONTINUES TO MOVE E/SEWD ACROSS
   THE TRI-STATE AREA...AN APPRECIABLY MOIST BOUNDARY LAYER /SURFACE

   SUPPORT THE NOTION FOR ADDITIONAL STRONG TO SEVERE STORM ACTIVITY.

   DEVELOP.  AS A RESULT OF THIS EXPECTED RISK...A WATCH
   EXTENSION-IN-AREA OR A NEW WATCH MAY BE NEEDED TO ADDRESS THE
   EVOLVING THREAT.
