   THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 525
   CONTINUES.
   
   SCATTERED DISCRETE STORM DEVELOPMENT IS UNDERWAY ALONG A QUASI-
   STATIONARY DRY LINE WEST OF THE INTERSTATE 35 CORRIDOR OF OKLAHOMA
   INTO NORTHWEST TEXAS...PARTICULARLY NEAR AND SOUTHWEST OF WICHITA
   FALLS.  A 40-50+ KT SOUTHWESTERLY DEEP LAYER MEAN FLOW FIELD IS
   ALLOWING FOR INITIATING STORMS TO PROPAGATE OFF THE DRY LINE...BUT
   INHIBITION BENEATH LINGERING VERY WARM ELEVATED MIXED LAYER AIR IS
   STILL ONLY SLOWLY WEAKENING.  THE SURFACE COLD FRONT IS CURRENTLY
   MERGING WITH THE DRY LINE AS FAR SOUTH AS THE ENID OKLAHOMA
   AREA...BUT STRONGER MID-LEVEL COOLING /CENTERED AROUND 700 MB/ IS
   JUST BEGINNING TO SPREAD EAST OF THE TEXAS/OKLAHOMA PANHANDLE
   REGION.  THE SURFACE COLD FRONT WILL CONTINUE TO OVERTAKE THE DRY
   LINE AND GRADUALLY PROGRESS INTO THE INTERSTATE 35 CORRIDOR BETWEEN
   NOW AND 00-02Z.  HOWEVER...IT MAY BE THAT STORMS REMAIN RATHER
   SCATTERED IN COVERAGE ACROSS CENTRAL OKLAHOMA AND NORTHWEST/NORTH
   CENTRAL TEXAS UNTIL STRONGER MID-LEVEL FORCING ARRIVES IN THE 01-03Z
   TIME FRAME.  SUPERCELLS WILL BE POSSIBLE...WITH THE RISK FOR LARGE
   HAIL/DAMAGING WIND GUSTS.
