   AREAS AFFECTED...AR...NE TX...NW LA
   
   CONCERNING...SEVERE THUNDERSTORM POTENTIAL 
   
   VALID 192043Z - 192245Z
   
   A FEW DAMAGING WIND GUSTS WILL BE POSSIBLE WITH A LINE MOVING EWD
   ACROSS AR. OTHER STORMS DEVELOPING ACROSS NE TX WILL CONTINUE TO
   POSE A MARGINAL WIND DAMAGE THREAT AS WELL OVER THE NEXT FEW HOURS.
   
   A CONVECTIVE BOW WITH A COLD POOL IS CURRENTLY MOVING EWD ACROSS
   SWRN AR. THE STORMS WILL CONTINUE TO TRACK ALONG AN EAST TO WEST
   INSTABILITY GRADIENT AND MAY TURN MORE TO THE SOUTHEAST INTO THE
   HIGHER SFC DEWPOINTS ACROSS NRN LA. DEEP LAYER SHEAR IS ONLY ABOUT
   20 KT WHICH WILL LIMIT THE SEVERE POTENTIAL. AN ADDITIONAL LIMITING
   FACTOR FOR DAMAGING WIND POTENTIAL IS THE SLOW FORWARD MOTION (25
   KT) OF THE LINE. STILL...STEEP LOW-LEVEL LAPSE RATES AND HIGH
   BOUNDARY LAYER MOISTURE CONTENT WILL RESULT IN A MARGINAL WIND
   DAMAGE THREAT AS THE LINE PROGRESSES ESEWD.
