Areas affected...portions of the Atlantic coastline of the Florida
Peninsula

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

Valid 111714Z - 111915Z

Probability of Watch Issuance...20 percent

SUMMARY...Widely scattered to scattered thunderstorms will pose a
risk for locally damaging wind gusts and perhaps isolated large hail
this afternoon, with the greatest potential expected primarily along
the Atlantic coastline of the Florida Peninsula.

DISCUSSION...Strong heating of a moist low-level air mass (as
sampled by the 12z TBW observed sounding) is contributing to
moderate to locally strong instability across much of the Florida
Peninsula, with latest mesoanalysis depicting MLCAPE ranging from
around 1500 J/kg to 2500+ J/kg. Thunderstorm coverage will increase
through the afternoon, with westerly effective shear of 35-45 kts
supporting organized updrafts. In a similar scenario to yesterday, a combination of multicells and marginal supercell structures will be
possible. With PWAT values of 1.75+ inches, water loading will
promote the potential for isolated damaging wind gusts with stronger downdrafts. Isolated large hail will also be possible with more
robust updrafts.

The greatest severe potential is expected along the Atlantic
coastline, where greater low-level moisture seaward of the
east-coast sea breeze will support greater buoyancy through the
afternoon. Watch issuance is unlikely at this time owing to the
forecast limited magnitude and coverage of the severe risk, but
trends will continue to be monitored.
