   THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 160
   CONTINUES.
   
   SUMMARY...DMGG WIND AND HAIL THREAT WILL PERSIST ACROSS SRN OK AND
   W-CNTRL TX PORTIONS OF WW 160.
   
   DISCUSSION...THE THREAT ACROSS WW 160 IS BIFURCATED WITH ONE REGIME
   EVOLVING ACROSS SRN OK AND ANOTHER OVER W-CNTRL AND NW TX...PER
   RECENT RADAR TRENDS.
   
   1. CONSOLIDATION OF STORMS INTO A BOWING QUASI-LINEAR SEGMENT ACROSS
   SRN OK HAS OCCURRED...APPROACHING THE ERN EDGE OF WW 160. RECENT
   OKLAHOMA MESONET OBSERVATIONS INDICATE GUSTS ASSOCIATED WITH THIS
   ACTIVITY ARE SUB-SEVERE...BUT SVR WIND GUSTS AND PERHAPS A
   WEAK/BRIEF EMBEDDED TORNADO CANNOT BE RULED OUT AS IT PROGRESSES EWD
   TOWARDS SERN OK. ALTHOUGH A NEW WW DOWNSTREAM IS NOT IMMINENT AS THE
   AIR MASS IS LESS UNSTABLE WITH EWD EXTENT...CONVECTIVE TRENDS WILL
   CONTINUE TO BE MONITORED.
   
   2. TSTMS LARGELY REMAIN CONFINED TO A E-W CORRIDOR ACROSS W-CNTRL
   TX...S OF I-20...WITH SOME INTENSIFICATION RECENTLY WITH STORM
   ENTERING TAYLOR COUNTY. THIS STORM WILL ENCOUNTER A PROGRESSIVELY
   MORE MOIST/UNSTABLE AIR MASS WITH ERN MOVEMENT...AND SHOULD
   EVENTUALLY MOVE INTO TORNADO WATCH 161. ADDITIONAL TSTM DEVELOPMENT
   IS STILL POSSIBLE INTO NW TX INVOF A NWD MOVING BOUNDARY...WITH 50S
   F DEWPOINTS EXTENDING NWWD TOWARDS CDS. THE PRIMARY THREATS WITH
   STORMS ACROSS THIS AREA WILL CONTINUE TO BE LARGE HAIL AND DMGG
   WINDS.
