Several severe thunderstorms are possible late this evening into the overnight from Tampa Bay northward into north Florida. ...Northern half of the FL Peninsula/coastal GA/SC... Evening water-vapor imagery shows a shortwave trough over the lower MS Valley and this feature will move east into the southern Appalachians by Saturday morning. Surface cyclogenesis will occur over the coastal waters east of the Mid-Atlantic states overnight while a cold front pushes east across north FL. The 00z raobs over the Slight-Risk area are weakly buoyant and low- to mid-level flow was relatively modest. However, as the mid-level wave approaches tonight, tropospheric flow will substantially increase and conditionally support storm organization. A few line segments and potentially a supercell or two will probably evolve on the north edge of the primary warm sector draped across north FL. A separate area may evolve near the west coast of the FL Peninsula late overnight as storms move onshore from the Gulf shelf waters. Damaging gusts and a tornado or two are the main risks with the strongest storms. ..Smith.. 12/14/2019 Read more
