   Areas affected...coastal MS/AL into the western FL Panhandle

   Concerning...Tornado Watch 633...

   Valid 261351Z - 261515Z

   The severe weather threat for Tornado Watch 633 continues.

   SUMMARY...Sporadic strong storms may produce gusty winds into midday
   across coastal Mississippi/Alabama and the western Florida
   Panhandle. A downstream watch is not expected.

   DISCUSSION...Clusters of convection oriented ahead of a cold front
   are moving eastward across southern MS/southeast LA this morning.
   This convection has largely been sub-severe, though some brief, weak
   low-level rotation has been noted where convection intersects a
   stationary boundary positioned roughly west to east near the coast
   into far southern MS. Regional VWP and 12z RAOB from LIX indicate
   enlarged, favorably curved low-level hodographs amid 40 kt effective
   shear magnitudes. 

   With eastward extent, strong shear profiles will persist near the
   coast/surface boundary. However, the stationary boundary will likely
   remain very near or just offshore the Gulf coast in AL toward the
   western FL Panhandle, and boundary-layer moisture steadily decreases
   (dewpoints falling into the 50s F with northeast extent). This will
   maintain stronger instability offshore as well. While low-level
   rotation may occur with convection offshore, tornado/severe
   potential is likely to remain limited, especially inland from the
   immediate coast. Locally gusty winds may accompany stronger storms,
   but overall severe potential will be low, precluding downstream
   watch issuance.
