   Concerning...Severe Thunderstorm Watch 127...

   Valid 182255Z - 190030Z

   The severe weather threat for Severe Thunderstorm Watch 127
   continues.

   SUMMARY...The severe threat continues across Severe Thunderstorm
   Watch 127, especially with an established supercell over western
   portions of the watch.

   DISCUSSION...KDGX radar data as of 2250Z depicts a well-established
   right-moving supercell over west-central MS -- embedded at the
   leading edge of what appears to be a remnant MCV. Over the next
   couple of hours, this supercell could maintain intensity as it
   continues tracking east-southeastward along the southern periphery
   of an outflow boundary. East-southeasterly storm-relative inflow
   will support continued surface-based streamwise vorticity, given
   clockwise low-level hodograph curvature (around 150 m2/s2 0-1km SRH
   per DGX VWP). Low-level shear may be modestly enhanced ahead of and
   to the right of the aforementioned MCV. Locally damaging winds and
   isolated hail (up to 1.5 inches) are the most likely concerns with
   this storm, though a brief tornado cannot be ruled out if it remains
   surface-based.
