   AREAS AFFECTED...SWRN THROUGH NCNTRL TX...SCNTRL OK
   
   CONCERNING...TORNADO WATCH 182...184...
   
   VALID 100636Z - 100730Z
   
   THE SEVERE WEATHER THREAT FOR TORNADO WATCH 182...184...CONTINUES.
   
   LARGE SCALE FORCING IS RESULTING IN A STRONG LOW LEVEL RESPONSE
   ACROSS THE SRN PLAINS AS SFC LOW BEGINS TO DEEPEN JUST SOUTH OF ABI
   OVER COLEMAN COUNTY.  CONTINUED DEEPENING IS EXPECTED THROUGH THE
   EARLY MORNING HOURS AS LOW TRACKS NEWD INTO SCNTRL OK...ALONG
   EXISTING QUASI-STATIONARY PORTION OF WARM FRONT.  AN EXPANSIVE AND
   INTENSE SQUALL LINE...WITH EMBEDDED SUPERCELL STRUCTURES...IS
   PROGRESSING EWD AT ROUGHLY 45-50KT ACROSS TX AND THIS WILL QUICKLY
   SURGE INTO WRN PORTIONS OF WW184.  DAMAGING WINDS CERTAINLY APPEAR
   POSSIBLE WITH THIS FAST MOVING SQUALL LINE...THOUGH ISOLATED
   TORNADOES CAN NOT BE RULED OUT AS WELL.  GREATEST TORNADO THREAT MAY
   ACTUALLY SHIFT INTO EXTREME SOUTH CENTRAL OK/NCNTRL TX NEAR THE RED
   RIVER IN CLOSER PROXIMITY TO RETREATING WARM FRONT.
