   AREAS AFFECTED...NRN AND NERN TX
   
   CONCERNING...SEVERE POTENTIAL...WATCH POSSIBLE 
   
   VALID 110755Z - 110900Z
   
   A WATCH MAY BE NEEDED SHORTLY AHEAD OF INCREASINGLY INTENSE
   CONVECTION ACROSS NRN TX.
   
   NUMEROUS VIGOROUS TSTMS HAVE DEVELOPED WITHIN ZONE OF ENHANCED LOW
   LEVEL ASCENT LEFT IN THE WAKE OF EARLIER INTENSE MCS AND BOW ECHO
   THAT MOVED ACROSS THE DFW AREA AND ESEWD TO PARTS OF NERN TX. WHILE
   THE EARLIER SYSTEM HAS MOVED WELL EAST...WIND PROFILER DATA
   INDICATED STRONG LOW LEVEL WARM AIR ADVECTION WAS CONTINUING ATOP
   RESIDUAL MCS COLD POOL. VERY STRONG INSTABILITY ACROSS THE REGION
   WILL LIKELY CONTINUE TO FUEL INTENSE UPDRAFTS WITHIN A RELATIVELY
   NARROW CORRIDOR FROM THE DFW METROPLEX ESEWD NEXT FEW HOURS. WEAK
   ELY COMPONENT TO LOW LEVEL FLOW...TOPPED BY INCREASINGLY STRONG WLY
   FLOW TO ABOUT 40KT BETWEEN 3-5KM WAS RESULTING IN SUFFICIENT SHEAR
   FOR SUPERCELLS.
   
   WHILE LARGE-SCALE REGIME APPEARS TO SUGGEST LIMITED POTENTIAL FOR
   WIDESPREAD DEVELOPMENT...THERE APPEARS TO BE MORE THAN SUFFICIENT
   INSTABILITY AND SHEAR...IN THE PRESENCE OF STRONG MESOSCALE
   FORCING...FOR SEVERE WIND AND HAIL POTENTIAL TO PERSIST WITH THIS
   ACTIVITY FOR AT LEAST A COUPLE MORE HOURS.
