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

...SUMMARY...
Isolated severe thunderstorms may affect parts of the western
Florida Peninsula late this afternoon and evening.

...Western Florida Peninsula...
Clusters of thunderstorms are ongoing over the eastern Gulf of
Mexico west/southwest of the Tampa/St Petersburg area at midday.
This inland-spreading precipitation will tend to delineate the
northward extent of modest surface-based destabilization this
afternoon as mid/some upper 60s F surface dewpoints otherwise expand
northward across the southern/central Florida Peninsula through
early/mid-evening. Although the passing shortwave trough will tend
to weaken into tonight, residually strong low/mid-level winds will
support the possibility of well-organized storms/few supercells near
and across the western Florida Peninsula as additional moistening
and destabilization occur. A few damaging wind gusts and/or a
tornado could occur late this afternoon and evening.
