...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS ACROSS THE
CENTRAL FL GULF COAST REGION...
...SUMMARY...
Isolated severe thunderstorms may affect parts of the western
Florida Peninsula through late this evening.
...01z Update...
Convection that persists along the southern fringe of the GA
short-wave trough continues to sag slowly southeast. Leading edge of
this activity has progressed inland across the Tampa Bay region
where modest lapse rates/buoyancy remain conducive for a few robust
updrafts. 00z sounding from TBW appears to be convectively
influenced, but nevertheless insightful with strong deep-layer
vertical shear and near-surface based instability present. Will
maintain MRGL Risk for the central Gulf Coast of the FL Peninsula
for primarily gusty winds with thunderstorms as they progress
inland.
