   Areas affected...Gulf coastal areas of Mississippi...Alabama...and
   the western Florida Panhandle

   Concerning...Tornado Watch 45...46...

   Valid 152040Z - 152215Z

   The severe weather threat for Tornado Watch 45, 46 continues.

   SUMMARY...The severe threat, including a few tornadoes, may develop
   along portions of the Gulf Coast if storms can continue developing
   along the shoreline. Tornado Watch expansions may be needed over the
   next few hours.

   DISCUSSION...Multiple supercells have developed along the LA/MS
   border and continue to track northeast with a tornado threat.
   However, storms continue to develop southward near Lake
   Pontchartrain, and as deep-layer ascent continues to increase over
   the Gulf Coast region, additional storms may develop along the
   shoreline. The MOB VAD has shown a slight but steady increase in
   hodograph size and curvature through the afternoon, with 0-3 km SRH
   approaching 600 m2/s2. Given rich Gulf moisture and associated
   buoyancy, the potential exists for tornadoes and damaging gusts if a
   sustained supercell structure can materialize. Should this scenario
   become apparent, ongoing Tornado Watches 45-46 may need to be
   expanded to the Gulf Coast.
