Areas affected...Portions of central Mississippi

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.
