   Areas affected...portions of extreme eastern Oklahoma into central
   Arkansas

   Concerning...Severe Thunderstorm Watch 629...

   Valid 170423Z - 170600Z

   The severe weather threat for Severe Thunderstorm Watch 629
   continues.

   SUMMARY...The severe threat continues across Severe Thunderstorm
   Watch 629. Damaging gusts remain the main threat with these storms
   over the next few hours.

   DISCUSSION...An MCS has materialized from congealing storms over the
   last few hours, with strong wind gusts over 50 mph recently
   reported. Preceding the eastern portion of the MCS is a cooler
   airmass, characterized by surface temperatures in the upper 70s to
   low 80s F. However, along the western periphery of the MCS track are
   warmer surface temperatures between 85-90 F, which also reside
   beneath the eastern periphery of a modest LLJ and accompanying WAA.
   As such, the portion of the MCS cold pool propagating into this
   airmass has the greatest chance for supporting stronger updrafts and
   corresponding downdrafts, which may penetrate the increasing MLCINH.
   Here, a few additional strong to severe gusts may occur over the
   next few hours.
