   Areas affected...Portions of north FL and coastal/southeast GA

   Concerning...Tornado Watch 4...5...

   Valid 091816Z - 091945Z

   The severe weather threat for Tornado Watch 4, 5 continues.

   SUMMARY...A tornado threat continues with small cells embedded
   within a line of thunderstorms moving quickly eastward.
   Severe/damaging winds also remain a concern.

   DISCUSSION...The line of thunderstorms across southeast GA has
   become a bit more broken recently, with a couple small cells noted.
   Extremely strong low-level shear remains present along/downstream of
   this activity across north FL and coastal/southeast GA, with recent
   VWPs from KJAX showing around 50 kt of 0-1 km shear, and effective
   SRH in excess of 500 m2/s2. Low-level rotation has been noted with
   these small cells, and a tornado threat remains apparent given the
   very favorable kinematic environment. With some modest daytime
   heating also occurring (surface temperatures generally reaching into
   the low to mid 70s), steepening low-level lapse rates should promote
   efficient downward momentum transfer of the very strong flow just
   off the surface. Severe/damaging downdraft winds will remain a
   concern with the more linear structures as the overall line advances
   quickly eastward through the afternoon.
