   AREAS AFFECTED...NORTHWEST TX

   CONCERNING...SEVERE THUNDERSTORM WATCH 99...

   VALID 210240Z - 210345Z

   THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 99
   CONTINUES.

   SUMMARY...THREAT FOR SEVERE HAIL AND ISOLATED SEVERE WIND GUSTS
   SHOULD BECOME INCREASINGLY CONFINED TO THE SOUTHERN PORTION OF
   REMAINING WATCH.

   DISCUSSION...THE MOST INTENSE CELL WITHIN THE CONVECTIVE CLUSTER
   ACROSS THE SOUTHEAST PANHANDLE/LOW ROLLING PLAINS WAS LOCATED OVER
   FLOYD COUNTY AS OF 0230Z. CONVECTION FARTHER NORTHEAST APPEARS TO
   HAVE WEAKENED...LIKELY IN RESPONSE TO STRENGTHENING MLCIN AND
   SEPARATION FROM THE INSTABILITY AXIS FARTHER SOUTHWEST. AS
   SUCH...THE STRONGER CONVECTION WILL PROBABLY CONTINUE TO EVOLVE
   SOUTHEASTWARD ALONG THE SOUTHWEST FLANK OF THE CLUSTER WHERE A FEED
   OF UPPER 50S SURFACE DEW POINTS EXISTS FROM THE PERMIAN BASIN/CONCHO
   VALLEY...AMID A 30-45 KT LOW-LEVEL JET PER AREA VWP DATA. WHILE THE
   SEVERE THREAT SHOULD REMAIN WITHIN A CONFINED SWATH...A RISK FOR
   HAIL AND WIND MAY PERSIST FOR THE NEXT FEW HOURS.
