...DISCUSSION...
UPPER TROUGHING LOCATED OVER THE ERN U.S. WILL GRADUALLY RELAX AND
MORE ZONAL FLOW IS EXPECTED TO DEVELOP NEAR THE INTERNATIONAL BORDER
BY EARLY NEXT WEEK.  LATEST MODEL GUIDANCE SUGGESTS A SIGNIFICANT
SHORT-WAVE TROUGH WILL PROGRESS ALONG THE U.S./CANADIAN BORDER TO A
POSITION FROM MB INTO THE DAKOTAS AT 06/12Z.  THIS FEATURE SHOULD
ENHANCE CONVECTIVE POTENTIAL ALONG ATTENDANT FRONTAL ZONE WHERE
DEEP-LAYER SHEAR COULD SUPPORT ORGANIZED UPDRAFTS.  IF
INTENSITY/TIMING OF SHORT WAVE IS CONSISTENT IN LATER MODEL GUIDANCE
THERE MAY BE A NEED FOR SEVERE PROBS ACROSS THE UPPER RED RIVER
REGION...POSSIBLY AS EARLY AS SUNDAY AFTERNOON.
