...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS IN THE
SOUTH-CENTRAL FL PENINSULA...

...SUMMARY...
A brief tornado and locally strong gusts remain possible, mainly
through late evening across the south-central portion of the Florida
Peninsula.

...South-central FL...
A convectively reinforced front has been sagging south across
central FL over the past couple hours. The bulk of convection has
weakened as it spread across the peninsula, with deeper/renewed
updrafts holding off the Gulf Coast, southwest of Tampa Bay to west
of Fort Myers. 23Z XMR and 00Z TBW soundings sampled less-than-moist
adiabatic lapse rates through much of the troposphere, which will
remain a limiting factor to intensification of convection over land.
But strong deep-layer shear (effective bulk values in excess of 50
kts) and moderate low-level hodograph enhancement will maintain a
low-probability tornado and strong wind gust threat through late
evening. This may be focused near the juncture of the eastern Gulf
convection with the undercutting boundary. With only minor
large-scale ascent, offshore convection should wane overnight and
severe potential across the peninsula should diminish. See MCD 2253
for additional short-term discussion.
