   AREAS AFFECTED...NWRN TX/SRN OK
   
   CONCERNING...SEVERE THUNDERSTORM WATCH 121...
   
   VALID 260022Z - 260115Z
   
   A NEW SEVERE TSTM WATCH IS BEING CONSIDERED ACROSS PARTS OF THE SERN
   TX PNHDL...SRN OK...AND NWRN TX. STORMS TRENDS OVER THE NEXT HOUR
   WILL BE MONITORED CLOSELY.
   
   ARC OF STRONG TO SEVERE STORMS FROM 35N FSI TO 30NW SPS TO 50SSE CDS
   CONTINUES MOVING TO THE SE AT ABOUT 30KT AND WILL BEGIN TO MOVE OUT
   OF THE SERN PORTION OF WW 121 OVER THE NEXT HOUR. DOWNSTREAM AIRMASS
   IS NOT PARTICULARLY UNSTABLE AND WILL CONTINUE TO DIABATICALLY COOL
   AND STABILIZE WITH THE LOSS OF INSOLATION. NONETHELESS...THERE IS
   STRONG MESOSCALE AND STORM SCALE ORGANIZATION TO THE ONGOING
   COMPLEX. LOW LEVEL ELY INFLOW AND PERPENDICULAR ORIENTATION OF SOME
   OF THE LINE SEGMENTS TO MODEST MID LEVEL FLOW SUGGEST THAT A SMALL
   WIND DAMAGE THREAT MAY PERSIST WITH THE STRONGER CELLS MOVING ALONG
   THE RED RIVER OVER THE NEXT COUPLE HOURS. IN ADDITION...SMALLER
   UPSTREAM CLUSTER OF SEVERE STORMS CLOSELY TIED TO MID LEVEL COLD
   POOL...NOW ABOUT 30E AMA...WAS TRACKING SE ABOUT 40KT AND SHOULD
   POSE A THREAT OF HAIL AND DAMAGING WINDS FOR AWHILE LONGER AS IT
   TRACKS INTO THE SERN TX PNHDL. THUS...A REPLACEMENT WATCH
   ENCOMPASSING BOTH THESE COMPLEXES MAY BE NEEDED SHORTLY.
