   Areas affected...Eastern AL...Western GA

   Concerning...Tornado Watch 498...

   Valid 102054Z - 102230Z

   The severe weather threat for Tornado Watch 498 continues.

   SUMMARY...The threat for brief tornadoes will continue into the
   early evening as convection spreads slowly eastward.

   DISCUSSION...At 2045Z, a band of convection continues across eastern
   AL into western GA. Weak rotation has occasionally been noted with
   the stronger discrete cells. While instability remains weak across
   the region (MLCAPE generally less than 500 J/kg), 0-1 km SRH of
   200-400 m2/s2 will support a brief tornado threat with the stronger
   convective elements, especially with any discrete elements in closer
   proximity to the effective warm frontal zone, where low-level flow
   remains backed. Some threat may spread slightly east of the watch
   with time, as additional development occurs ahead of the main
   convective band. Local watch extension may be needed at some point
   depending on the intensity of any new development.
