   Concerning...Tornado Watch 76...

   Valid 242306Z - 250030Z

   The severe weather threat for Tornado Watch 76 continues.

   SUMMARY...A couple supercells could mature over parts of
   south-central MS during the next hour or two -- posing an increased
   tornado threat.

   DISCUSSION...Recent radar data from DGX depicts a loosely organized
   supercell tracking north-northeastward across parts of south-central
   MS. This storm is evolving along the eastern edge of the warm sector
   and slightly south of an east/west-oriented marine front --
   demarcating the richer boundary-layer moisture (middle/upper 60s
   dewpoints) to the south. This portion of the warm sector had
   substantial diurnal destabilization/steepening low-level lapse rates
   amid the rich moisture (see 21Z observed JAN sounding). Ahead of the
   ongoing storm, visible satellite imagery shows billow clouds
   transitioning to HCRs -- indicative of a favorable overlap of
   boundary-layer instability and low-level shear. The VWP hodograph
   from DGX confirms this, indicating an expanding/clockwise-turning
   hodograph as well. If the developing storms can maintain appreciable
   residence time south of the marine warm front during the next couple
   hours, this corridor could be locally favorable for tornadoes.
