...NO SEVERE THUNDERSTORM AREAS FORECAST...

...SUMMARY...
Isolated thunderstorms should remain confined to parts of the
southern Florida Peninsula today. Severe thunderstorms are not
expected.

...Synopsis and Discussion...
An upper trough will amplify over the central CONUS and MS Valley
through tonight, while a surface cold front also surges eastward.
Low-level moisture will likely remain insufficient to support any
thunderstorms across these regions. The only appreciable risk for
thunderstorms today appears to be confined to portions of the
southern FL Peninsula, where a weak easterly wave and modest
low-level convergence along sea breeze boundaries should be present.
Although MLCAPE may increase to 1000-1500 J/kg this afternoon across
south FL, weak shear is expected to limit thunderstorm organization.
