...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS ACROSS PARTS OF
THE FLORIDA PENINSULA...

...SUMMARY...
Isolated damaging winds and a brief tornado or two are possible
across parts of the Florida Peninsula late this afternoon and
evening.

...Florida Peninsula...
Thunderstorms will develop today across the north-central to
northeast Gulf along a largely west-east oriented front. Downstream
cloudiness/precipitation along and north of the front will support
pronounced differential heating across the north-central FL
Peninsula. Latest guidance continues to suggest that scattered
convection will move onshore late this afternoon/early evening
within broadly cyclonic flow aloft over the Southeast. Poor
mid-level lapse rates will be a limiting factor to convective
intensity (reference 12Z sounding from TBW). But, adequate
deep-layer shear will exist for transient mid-level rotation. With a
warm boundary layer forecast across central FL, a few strong gusts
capable of localized damaging winds are possible. Modest low-level
shear/SRH may also be sufficient for a brief tornado or two.
