   The severe weather threat for Severe Thunderstorm Watch 392, 393
   continues.

   SUMMARY...A linear MCS, associated with strong wind gusts, will move
   across southern and eastern Oklahoma over the next few hours, and
   into far north Texas and far western Arkansas later tonight.
   Although intensity with the line has decreased, there still remains
   a possibility that the line could re-generate during the overnight
   period.

   DISCUSSION...Latest mosaic radar imagery shows a line of strong
   thunderstorms over southern and east-central Oklahoma. This line is
   associated with a linear MCS that is located near the northern edge
   of a strongly unstable airmass. Immediately to the south of the MCS,
   MLCAPE is estimated by the RAP to be in the 3500 to 5000 J/kg range.
   RAP forecast soundings overnight within this airmass near the Red
   River and in eastern Oklahoma have substantial directional shear in
   the lowest 3 km, which combined with the strong instability,
   suggests the line could be associated with a few marginally severe
   wind gusts. It still remains possible the line could re-generate as
   it moves southeastward along the instability gradient.
