SPC MESOSCALE DISCUSSION 1065 FOR THE SERN 2/3 OF ND...
   CONCERNING...SEVERE THUNDERSTORM WATCH 0402...
   
   VALID 090855Z - 091100Z
   
   THUNDERSTORMS AND ASSOCIATED SEVERE THREAT APPEAR TO BE DECREASING
   ACROSS WW AREA.  WW MAY BE CANCELLED EARLY.
   
   MESOSCALE CONVECTIVELY-INDUCED CYCLONIC CIRCULATION HAS DEVELOPED
   AND IS NOW MOVING ACROSS W CENTRAL ND.  THIS COMBINED WITH VEERING
   LOW-LEVEL JET IS SHIFTING THE MESOSCALE FOCUS FOR UVV EWD -- AWAY
   FROM THE STRONGER SYNOPTIC-SCALE MID-LEVEL FLOW OVER THE NRN HIGH
   PLAINS.  THIS COMBINED WITH RADAR IMAGERY SHOWING THAT AN OUTFLOW
   BOUNDARY HAS SURGED EWD INTO SERN SD THUS RESULTING IN
   INCREASINGLY-ELEVATED CONVECTION SUGGESTS THAT REMAINING SEVERE
   THREAT SHOULD CONTINUE TO SLOWLY DECREASE.
   
   ASSUMING CURRENT TRENDS CONTINUE...WW MAY BE CANCELLED BEFORE ITS
   SCHEDULED EXPIRATION.
