   CONCERNING...TORNADO WATCH 207...
   
   VALID 020008Z - 020145Z
   
   THE SEVERE WEATHER THREAT FOR TORNADO WATCH 207 CONTINUES.
   
   CONDITIONS REMAIN RIPE FOR A FEW INTENSE STORMS WITH TORNADO
   POTENTIAL...VERY LARGE HAIL...AND FLOODING RAINS...ACROSS PARTS OF
   SCNTRL TX THIS EVENING.
   
   CURRENTLY...MOST INTENSE ACTIVITY WAS FOCUSED ALONG RESIDUAL OUTFLOW
   BOUNDARY WHERE ONE PARTICULARLY LONG-LIVED SUPERCELL WAS ANCHORED
   OVER MASON COUNTY. ADDITIONAL STRONG TO OCCASIONALLY SEVERE ACTIVITY
   WAS NOTED IN BURLESON COUNTY WHERE STRONGER LOW LEVEL JET IS FOCUSED
   INTO THE BOUNDARY AND SHOULD SUPPORT EXCESSIVE RAIN FROM REPEAT
   CONVECTION. VERY STRONG INSTABILITY RESIDES ALONG AND SOUTH OF THE
   OUTFLOW AND SHOULD CONTINUE TO FUEL TSTM ACTIVITY THIS EVENING.
   REGION IS BENEATH THE SRN PERIPHERY OF MODEST WLY MID LEVEL FLOW
   /ABOUT 40KT/. FURTHERMORE...DIRECTIONAL SHEAR...ESPECIALLY INVOF THE
   OUTFLOW...IS MORE THAN ADEQUATE TO SUSTAIN LOW LEVEL MESOCYCLONES
   AND A TORNADO OR TWO FOR CELLS REMAINING NEAR THIS FEATURE.
   
   UNLESS STORM SCALE INTERACTIONS LEAD TO UPSCALE DEVELOPMENT...IT
   CURRENTLY APPEARS THAT CONVECTION MAY NOT INCREASE SIGNIFICANTLY IN
   COVERAGE THROUGH LATER TONIGHT. STRONGER LARGE SCALE DYNAMICS
   SUPPORTING MORE WIDESPREAD ASCENT ACROSS THE REGION APPEAR TO BE
   WEAKENING ATTM AND IT DOES NOT APPEAR THAT ADDITIONAL WATCHES WILL
   BE NEEDED.
