   The severe weather threat for Severe Thunderstorm Watch 241
   continues.

   SUMMARY...A few strong gusts remain possible with generally
   weakening thunderstorm activity approaching the Wichita Falls
   vicinity through 5-6 AM CDT.  Renewed strong to severe thunderstorm
   development remains possible to the northwest through north of
   Abilene.

   DISCUSSION...There has been some recent weakening of thunderstorm
   intensities, with downdrafts and associated surface outflow becoming
   more prominent.  The largest of these is now surging
   east-northeastward at up to 30-35 kts, toward the Wichita Falls, TX
   vicinity, as another smaller downburst near Fredrick, OK approaches
   Wichita Falls from the northwest.  

   While new/intensifying convection is possible as the outflows merge,
   this may be short-lived as the more prominent east-northeastward
   advancing outflow tends to progress into less unstable air across
   and northeast of the Red River vicinity.  However, renewed vigorous
   thunderstorm development still appears possible upstream, above the
   southwestern flank of the cold pool across western north Texas, as
   the modest veering low-level low-level jet focuses lift near the
   periphery of the warmer and more strongly capping elevated
   mixed-layer air.
