   Concerning...Tornado Watch 158...

   Valid 282313Z - 290015Z

   The severe weather threat for Tornado Watch 158 continues.

   SUMMARY...Severe threat will spread east of ww158 shortly. New
   tornado watch will likely be warranted immediately downstream.

   DISCUSSION...Sustained low-level warm advection will continue across
   the lower MS Valley early this evening in association with LLJ that
   is focused from the lower Sabine River Valley into western AR. Deep
   convection that evolved upstream over central TX has propagated east
   as the LLJ has shifted downstream. Multiple thunderstorm clusters
   have evolved with the leading edge of this activity now surging into
   Harrison/Panola County region. Over the next few hours this complex
   will advance beyond the eastern border of ww158 and a new tornado
   watch will likely be issued soon to account for this risk.
