   VALID 250411Z - 250515Z
   
   NUMEROUS EMBEDDED SUPERCELL STRUCTURES AND BOW-TYPE FEATURES MAKE UP
   A MORE EXTENSIVE SQUALL LINE THAT EXTENDS NE-SW ACROSS THE TORNADO
   WATCH FROM NWRN AL...SWWD INTO SRN LA.  OVERALL LINE APPEARS TO BE
   SHIFTING ESEWD AT ROUGHLY 20KT...WITH MUCH FASTER INDIVIDUAL STORM
   MOTIONS.  IMPRESSIVE SHEAR PROFILES ARE OBSERVED AHEAD OF THIS LINE
   WITH 50KT JUST OFF THE SURFACE...VEERING TO MORE THAN 70KT WITHIN A
   FEW KM ACROSS ECNTRL MS INTO NRN AL.  ALTHOUGH INSTABILITY IS NOT
   PARTICULARLY NOTEWORTHY...SFC...OR NEAR-SFC BASED SUPERCELL
   STRUCTURES REMAIN CAPABLE OF PRODUCING TORNADOES.  BOW-TYPE
   STRUCTURES COULD EASILY PRODUCE DAMAGING STRAIGHT LINE WINDS AS
   WELL.
