   Concerning...Tornado Watch 685...

   The severe weather threat for Tornado Watch 685 continues.

   SUMMARY...Local risk for brief tornadoes will continue -- with
   greatest short-term potential over central portions of the Florida
   Panhandle.

   DISCUSSION...Latest surface analysis reveals a nearly stationary
   north-south trough -- acting as a pseudo warm front and, as such,
   source of enhanced low-level vorticity -- extending from the
   Franklin/Gulf County vicinity on the Florida Coast, northward across
   far western Georgia and into the southern Appalachians.  This
   boundary reflects the discontinuity between the moist/tropical
   airmass to the east, and the continental airmass to the west. 
   Several/continued brief low-level spin-ups have been observed over
   the past couple of hours within this zone, and expect this local
   enhancement of tornado potential to continue over the next couple of
   hours, given increasingly favorably low-level flow and the nearly
   stationary character of this north-south boundary.
