   Areas affected...Northwest TX...OK...Northwest AR

   Concerning...Severe Thunderstorm Watch 386...

   Valid 010324Z - 010430Z

   The severe weather threat for Severe Thunderstorm Watch 386
   continues.

   SUMMARY...Scattered thunderstorms will persist across the southern
   Plains into the early morning hours; however, only isolated severe
   is expected with this activity.

   DISCUSSION...Low-level warm advection is focused across the TX South
   Plains this evening as LLJ is gradually strengthening across this
   region. This appears to be partly responsible for renewed convective
   development in the vicinity of Stonewall County TX. Additional
   convection is beginning to strengthen across the southeast TX
   Panhandle along an ill-defined outflow-reinforced synoptic front.
   Hail may be noted with this activity across the high plains due to
   steeper lapse rate environment along the southern fringe of stronger
   northwestely mid-level flow. Considerable convective overturning
   across OK has stabilized much of the state and severe threat appears
   to be waning. Although isolated damaging wind gust or hail may be
   noted with convection near the Red River, new WW is not expected at
   this time.
