   Concerning...Severe Thunderstorm Watch 626...628...

   Valid 300252Z - 300415Z

   The severe weather threat for Severe Thunderstorm Watch 626, 628
   continues.

   SUMMARY...Upscale growth of convection will continue over the next
   several hours, with damaging winds likely continuing overnight.

   DISCUSSION...Smaller linear segments of intense multicellular
   convection have been congealing over the past couple of hours due to
   cold pool mergers, and increased low-level ascent at the terminus of
   a developing LLJ. Though the boundary layer has recently begun to
   decouple, stabilization is expected to be gradual given the
   relatively deep moisture in place. Ample buoyancy, with up to 4000
   J/kg MUCAPE noted across much of the discussion area, will continue
   to fuel vigorous updrafts. Meanwhile strong low-level shear,
   provided by the the developing LLJ, will mitigate cold pools from
   undercutting convection to a degree, suggesting that potentially
   long-lived MCS structures may be realized. As such, damaging wind
   gusts are expected to accompany the aforementioned linear segments
   for several more hours.
