   NEXT HOUR OR SO WITH TSTM CLUSTER OVER THE SRN NEB PANHANDLE AND
   EXTREME NERN CO.  THIS COMPLEX IS EXTRAPOLATED TO MOVE SEWD INTO

   MOVING SEWD AND GENERALLY JUST NORTH AND PARALLELING AFOREMENTIONED
   BOUNDARY BASED ON THE LATEST RADAR TRENDS.  THIS TSTM CLUSTER WILL
   LIKELY CONTINUE TO FAVOR A SEWD MOTION WHERE DEEPER FRONTAL LIFT IS
   SUSTAINING FORCED ASCENT FOR PARCEL/S TO ATTAIN THEIR LFC.

   WIND/LARGE HAIL THREAT FOR THE NEXT HOUR OR SO AND THEREAFTER
   PERHAPS POSING ONLY AN ISOLD LARGE HAIL THREAT.
