   Areas affected...Parts of southern Georgia into northern Florida

   Concerning...Severe potential...Watch unlikely 

   Valid 212214Z - 212345Z

   Probability of Watch Issuance...5 percent

   SUMMARY...Locally strong gusts and/or marginally severe hail could
   occur with a couple isolated storms over the next couple hours.

   DISCUSSION...A couple isolated storms have developed across far
   southern GA -- immediately ahead of a cold front draped across the
   area. These storms are tracking slowly southeastward into northern
   FL -- where earlier heating of a moist boundary layer (middle 70s
   dewpoints) has yielded moderate surface-based instability. Given
   30-40 kt of midlevel westerly flow sampled by the JAX VWP, these
   cells may continue to exhibit marginal/transient supercell
   characteristics -- and locally strong gusts/marginally severe hail
   will be possible for the next couple hours.
