   Areas affected...far southeastern GA and adjacent northern FL

   Concerning...Tornado Watch 78...

   Valid 312040Z - 312145Z

   The severe weather threat for Tornado Watch 78 continues.

   SUMMARY...Risk for locally damaging winds and a couple of tornadoes
   continues across valid portions of the watch, with greatest risk
   apparent over northwestern Florida at this time.

   DISCUSSION...Latest radar loop shows storms becoming a bit more
   organized over the past hour or so -- particularly over northern
   Florida and adjacent southeastern Georgia.  In particular, WSR-88D
   VWP data indicated two tornadoes in Madison County at one point in
   the past 15 minutes -- one over central portions of the county and
   one to the south.

   This portion of the convective band appears to be moving through a
   maximized area of low-level moisture (low 70s dewpoints) and
   correspondingly greater CAPE (an axis of 1000 J/kg mixed-layer CAPE
   per the most recent RUC-based surface OA data).  Though low-level
   flow has becoming increasingly veered/west-southwesterly ahead of
   the storms, ample low-level shear persists -- suggestive that
   tornado risk will persist over the next hour.
