   Concerning...Tornado Watch 29...

   Valid 171801Z - 171930Z

   The severe weather threat for Tornado Watch 29 continues.

   SUMMARY...A local expansion of tornado watch 29 may be needed.

   DISCUSSION...A favorable tornadic environment exists across central
   Alabama with temperatures in the mid 70s and dewpoints in the upper
   60s yielding MLCAPE around 1000 to 1500 J/kg. In addition, this area
   is in close proximity to the warm front where low-level winds are
   backed and low-level SRH is maximized. A supercell which developed
   in Dallas County has taken advantage of this favorable tornadic
   environment with radar evidence of a tornado near the Dallas Autauga
   county line. There is considerable question regarding the longevity
   of the tornado threat with this activity. The warm sector is
   advecting northeastward, but this storm may eventually move to the
   cool side of the boundary. However, given the potential for this
   storm to potentially move out of watch 29 and additional shower
   development to it's south and southeast which could deepen and
   become tornadic, watch 29 may need to be expanded into eastern
   Alabama.
