   Areas affected...Northern Florida and far southern Georgia

   Concerning...Tornado Watch 256...

   Valid 180146Z - 180315Z

   The severe weather threat for Tornado Watch 256 continues.

   SUMMARY...The severe weather threat will persist through the
   evening.

   DISCUSSION...Scattered supercells continue within tornado watch 256
   and will continue to pose a threat for damaging wind gusts and
   potentially a tornado. Thus far the tornado threat has been limited,
   likely related to weak low-level lapse rates and lack of greater
   low-level updraft acceleration. Shear has also weakened with eastern
   extent and therefore, expect that the greater coverage threat for
   the remainder of the evening will be damaging wind gusts.
   Nonetheless, there is still some low-level cyclonic curvature and a
   brief tornado cannot be ruled out.
