...NO SEVERE THUNDERSTORM AREAS FORECAST...

...SUMMARY...
Organized severe thunderstorms are unlikely today.

...Central Florida Peninsula...
Showers/some thunderstorms are common early today near the residual
front from the northern Gulf to the north-central Florida Peninsula.
A weak surface low/frontal wave is expected to develop over the
northeast Gulf today, with some guidance advertising an increase in
low/mid-tropospheric flow late today into tonight, as early day wind
profiles are otherwise weak (reference 12z observed sounding from
Tampa Bay). The more shear-optimistic guidance scenarios, via
strengthening/veering flow with height, suggest wind profiles could
trend conducive to weak/transient supercells. That said,
destabilization across the Peninsula near the front is questionable
with the expected persistence of marginal, thin CAPE profiles and
poor (5-5.5 C/km) mid-level lapse rates. A few storms may exhibit
brief/transient low-level rotation offshore, but the threat for
persistent, rotating updrafts reaching near-shore/inland areas later
today into tonight currently appears low.
