   Areas affected...Parts of southern/central AR into northwest MS

   Concerning...Severe Thunderstorm Watch 28...

   Valid 091703Z - 091830Z

   The severe weather threat for Severe Thunderstorm Watch 28
   continues.

   SUMMARY...The risk of severe hail and locally damaging gusts
   continues across Severe Thunderstorm Watch #28, and will gradually
   spread eastward into MS -- where a new watch may eventually be
   needed.

   DISCUSSION...A cluster of thunderstorms continues tracking eastward
   across central AR, with deeper/embedded cores noted along the
   southern fringes of this activity. As low-level moisture continues
   streaming northward amid filtered diurnal heating, the stronger
   cores capable of producing severe hail and locally damaging gusts
   may remain focused over the southern periphery of the larger
   cluster. With time, these storms will continue spreading eastward
   into northern/central MS, with additional warm-advection-driven
   development also possible. Increasing buoyancy into this corridor
   and around 40 kt of effective shear will promote a continued risk of
   large hail and damaging gusts. While timing is uncertain, a
   downstream watch may eventually be needed.
