Areas affected...the eastern FL Peninsula

Concerning...Severe potential...Watch unlikely=20

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.=20

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.
