   Areas affected...the eastern FL Peninsula

   Concerning...Severe potential...Watch unlikely 

   Valid 181816Z - 182015Z

   Probability of Watch Issuance...20 percent

   SUMMARY...Isolated severe storms are possible this afternoon.

   DISCUSSION...A very warm and moist airmass is in place across the FL
   Peninsula this afternoon, with temperatures rising into the mid 90s
   F and dewpoints well into the 70s F. Recent objective mesoanalyses
   and the 15Z XMR sounding (modified for current surface conditions)
   indicate that MLCAPE has increased to near/above 2500 J/kg across
   most of the peninsula early this afternoon. Meanwhile, modest
   midlevel southwesterly flow is supporting effective shear of 30-40
   kt across the region, resulting in a conditionally favorable
   environment for somewhat organized convection. 

   Decreasing MLCINH could result in isolated storm initiation over a
   larger portion of the central/eastern peninsula, but the greatest
   storm coverage is expected to focus near the east coast sea breeze
   later this afternoon. A few stronger multicells and perhaps a couple
   of supercells will be possible, with a threat of isolated hail and
   localized severe gusts. In addition, a brief tornado cannot be ruled
   out as cells interact with the sea breeze boundary.
