   Areas affected...central Alabama

   Concerning...Tornado Watch 671...

   Valid 130028Z - 130230Z

   The severe weather threat for Tornado Watch 671 continues.

   SUMMARY...A small area of conditional tornado potential remains over
   parts of central Alabama, but probabilities will continue to drop
   over time.

   DISCUSSION...Prior to sunset, visible satellite showed areas of
   agitated CU along a confluence line, and west of a warm front which
   now stretches from near Birmingham AL into southwest GA. A moist air
   mass remains over the region, with precipitable water in excess of
   1.80". Scattered cells, primarily elevated, developed over
   east-central AL, and persist this evening. 

   Despite the moist troposphere, instability is not particular strong,
   and, confined to a relatively narrow axis just west of the warm
   front. Low-level shear remains favorable in a conditional sense for
   rotating storms/supercells, however, it appears unlikely at this
   point that any robust convective machinations will develop to take
   advantage of said shear.
