   THE SEVERE WEATHER THREAT FOR TORNADO WATCH 265 CONTINUES.
   
   LOW LEVEL WARM ADVECTION APPEARS TO BE PARTLY RESPONSIBLE FOR NEW
   TSTM DEVELOPMENT ACROSS SRN ND.  LATEST VIS IMAGERY SUGGESTS BACK
   EDGE OF DEEPER CONVECTION IS OCCURRING OVER SIOUX COUNTY AND THIS
   ACTIVITY SHOULD SPREAD/DEVELOP EWD OVER THE NEXT FEW HOURS.  WITH A
   FAIRLY SIGNIFICANT CAP IN PLACE ACROSS THE ERN DAKOTAS INTO ERN NEB
   IT APPEARS ANY STORMS THAT SPREAD EAST OF ONGOING WW WILL QUICKLY
   BECOME ELEVATED.  THIS SHOULD LIMIT ANY TORNADIC POTENTIAL TO A
   NARROW WEDGE OF INSTABILITY ACROSS SD INTO SCNTRL ND BEFORE BOUNDARY
   LAYER DECOUPLES OVER THE NEXT FEW HOURS.
