This MCS is now spreading across northern AL and appears to be gradually expanding in areal extent. Earlier supercell structures have mostly merged within the broader precip shield, and latest MESH cores support this with hail signatures primarily below severe levels. As the MCS propagates downstream, locally damaging winds, and marginal severe hail will be the primary concerns. Farther south across the lower MS Valley, both JAN and LIX exhibit strong deep layer shear and modest-strong buoyancy. Scattered robust convection persists along this corridor, driven in part by weak low-level warm advection and diurnal heating. For the next few hours, isolated severe will continue within this environment, but nocturnal cooling should lead to few storms by mid evening, along with weaker convection. Southern AZ: Scattered convection has developed along the northern periphery of an upper low advancing east across northwest Mexico. This activity will continue spreading north this evening as favorable large-scale ascent is noted near the international border. Nocturnal cooling should lead to weaker updrafts and the overall risk of damaging winds/large hail should gradually wane with time.
