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. Current thinking is that the overall severe-threat will remain too localized/marginal for a watch consideration. ..Weinman/Guyer.. 03/06/2024 ...Please see www.spc.noaa.gov for graphic product...
