   VALID 111239Z - 111345Z
   
   THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 372
   CONTINUES.
   
   GIVEN A RECENT INCREASE IN TSTM ACTIVITY ACROSS THE DAL/FWD
   METROPLEX AND ADDITIONAL STORMS DEVELOPING WWD ALONG A SURFACE FRONT
   EXTENDING INTO THROCKMORTON...WFO FWD WILL BE EXTENDING WW 372 BOTH
   TEMPORALLY AND SPATIALLY.  THE STRONGEST STORMS WILL REMAIN CAPABLE
   OF PRODUCING HAIL...STRONG WINDS AND HEAVY RAINFALL RATES GIVEN
   LIKELIHOOD FOR ADDITIONAL EWD TRAINING ALONG THE SURFACE FRONT.
   
   DESPITE LACK OF ANY MODEL GUIDANCE ACROSS N TX WITH THIS ONGOING
   ACTIVITY...A 30-35 KT SSWLY LLJ EXTENDING FROM THE EDWARDS PLATEAU
   INTO NORTH CENTRAL TX WILL MAINTAIN AN INFLUX OF MOISTURE/MODERATE
   INSTABILITY THIS MORNING.  MODEL DATA DOES SUGGEST LLJ SHOULD WEAKEN
   BY LATE MORNING WHICH WOULD TEND TO LIMIT THE OVERALL SEVERE WEATHER
   THREAT BY THAT TIME.  UNTIL THEN...MODERATE INSTABILITY AND
   EFFECTIVE BULK SHEAR AROUND 40 KT WILL SUPPORT ADDITIONAL STRONG TO
   SEVERE STORMS PRODUCING HAIL AND STRONG WIND GUSTS.
