Mesoscale Discussion 0193

Areas affected...Portions of the western Florida Peninsula

Concerning...Severe potential...Watch unlikely=20

Valid 060147Z - 060345Z

Probability of Watch Issuance...20 percent

SUMMARY...Isolated damaging gusts and possibly a brief/weak tornado
could accompany an approaching mesoscale convective system from the
west in the next hour or so. A watch is not currently expected.

DISCUSSION...A loosely organized quasi-linear convective system is
tracking eastward at around 30-35 kt across the eastern Gulf of
Mexico, and is approximately 35-40 miles west of Tampa Bay FL. While
the latest IR satellite trends suggest a gradual weakening of this
system as it encounters cooler sea-surface temperatures and weaker
buoyancy offshore of the western FL Peninsula, around 40 kt of
midlevel westerly flow perpendicular to the established cold pool
should support some maintenance as it approaches the coast.
Regardless, antecedent heating/destabilization of a relatively moist
airmass (upper 60s to lower 70s dewpoints) over the peninsula could
support locally damaging gusts as it moves ashore in the next hour
or so, though the onset of nocturnal cooling could offset this to an
extent. In addition, small clockwise-curved hodographs could support
a brief/weak tornado along the immediate coastal areas, though the
stronger low-level flow/shear is largely displaced to the north,
where earlier convection/cloud coverage limited destabilization.=20

Current thinking is that the overall severe-threat will remain too
localized/marginal for a watch consideration.
