   CONCERNING...SEVERE THUNDERSTORM WATCH 525...
   
   VALID 210056Z - 210230Z
   
   THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 525
   CONTINUES.
   
   TRENDS WILL CONTINUE TO BE MONITORED FOR THE POSSIBILITY OF AN
   ADDITIONAL WW EAST OF WW 525.
   
   THE DRY LINE ACROSS NORTHWEST TEXAS INTO PARTS OF SOUTHWESTERN
   OKLAHOMA IS ACTUALLY RETREATING WESTWARD...BUT SCATTERED
   STRONG/SEVERE STORMS THAT EARLIER DEVELOPED OFF OF IT CONTINUE TO
   DEVELOP NORTHEASTWARD...TO THE WEST/NORTHWEST OF THE DALLAS/FORT
   WORTH METROPLEX INTO SOUTH CENTRAL OKLAHOMA.  THIS ACTIVITY MAY
   BEGIN TO WEAKEN THROUGH 01-03Z...AS INHIBITION INCREASES FOR WARM
   SECTOR BOUNDARY LAYER PARCELS.
   
   DEEPENING/INCREASING CONVECTIVE DEVELOPMENT HAS BEEN OCCURRING ALONG
   THE DRY LINE NEAR THE INTERSTATE 35 CORRIDOR...IN THE VICINITY OF
   OKLAHOMA CITY.  THIS ACTIVITY MAY INTENSIFY INTO SUPERCELLS BETWEEN
   NOW AND 02-03Z...BUT IT STILL APPEARS THE MORE WIDESPREAD STORM
   DEVELOPMENT WILL OCCUR AS THE COLD FRONT CONTINUES TO MERGE WITH THE
   DRY LINE...PROBABLY NEAR/EAST OF INTERSTATE 35 BETWEEN 02-04Z.  
   
   THE RISK FOR LARGE HAIL WILL LIKELY BE THE PRIMARY SEVERE THREAT
   INITIALLY...BUT POTENTIALLY DAMAGING WIND GUSTS SHOULD BE AN
   INCREASING CONCERN AS STORM COVERAGE INCREASES THIS EVENING.
