   Areas affected...Southern Mississippi...Southwest Alabama

   Concerning...Tornado Watch 684...

   Valid 260104Z - 260230Z

   The severe weather threat for Tornado Watch 684 continues.

   SUMMARY...An isolated tornado threat will continue across parts of
   southern Mississippi and southwestern Alabama over the next couple
   of hours. However, the threat should become marginal enough to let
   Tornado Watch 684 expire at 02Z. A local extension in area and time
   may be needed to cover areas the continue to have a tornado threat
   after 02Z.

   DISCUSSION...The latest radar imagery shows a band of thunderstorms
   from far southern Mississippi extending northeastward into western
   Alabama. Several discrete cells are still ongoing along the eastern
   edge of the rain band across the northern part of WW 684. These
   cells are located along the northern edge of the stronger
   instability. In addition, the Mobile WSR-88D VWP shows some
   directional shear in the lowest 1 km AGL with 0-1 km shear near 30
   kt. This should be enough to continue an isolated tornado threat
   this evening. However, the discrete cells currently about 50 statute
   miles to the north of Mobile, should continue to move northward away
   from the stronger instability late this evening. For this reason,
   the tornado threat is expected to become more marginal with time and
   the tornado watch will be allowed to expire at 02Z. The tornado
   threat may redevelop later tonight as additional discrete cells
   approach the coast associated with Tropical Storm Olga.
