   The severe weather threat for Severe Thunderstorm Watch 588
   continues.

   SUMMARY...Scattered severe thunderstorms will spread across
   eastern/southern portions of ww588 this evening.

   DISCUSSION...Several clusters of deep convection have developed
   immediately ahead of central Plains short-wave trough. One
   thunderstorm cluster, northwest/north of LHX, is propagating
   southeast along the primary instability axis where MLCAPE is on the
   order of 2000 J/kg. As the short wave shifts east, northwesterly
   flow will deepen as LLJ begins to strengthen just downstream across
   the TX/OK Panhandle region. Current thinking is continued maturation
   of this activity will be noted over the next few hours with
   additional convection expected to increase in areal coverage over
   the southern portions of ww588. With time an MCS should materialize
   as it propagates toward the OK Panhandle.
