The multi-day severe weather threat will continue this weekend, now targeting the southeastern US as the cold front tracks farther to the south and east associated with a storm system to the north. A rather potent mid-level jet will crossover this region. That paired with high moisture and instability will make for a very conducive environment for thunderstorms and several severe ones.
This morning, there are two Mesoscale Convective Systems that continue to track to the south and east. These complexes will weaken by midday and should ultimately dissipate. Before then, however, central Mississippi, Alabama, and Georgia and inland South Carolina will have to deal with these storms. Torrential rainfall, frequent lightning, and gusty winds will be the main risks that these storms will bring. Isolated severe weather activity also cannot be ruled out.
A separate round of storms will then form in the afternoon over the southern Appalachian Mountains. These storms will be more scattered and supercellular, posing the risk for damaging winds, large hail, and a tornado or two. These storms will track southeastward into the evening hours, affecting portions of the Carolinas, Georgia, and northern Florida. Much of this convective activity should then either weaken or dissipate overnight Saturday.
On Sunday, coastal South Carolinas into southern Georgia and northern Florida will remain at risk for severe thunderstorms with hit or miss thunderstorms expected to form in the afternoon. Wind and hail will continue to be the main threats from these intense storms.
