A few strong to severe thunderstorms are possible across portions of eastern Mississippi into Alabama on Thursday. ...Southeast... A shortwave upper trough will move across the Southeast through Thursday evening before moving offshore over the Atlantic during the nighttime hours. Stronger deep-layer flow associated with a 55-65 kt jet streak within the base of the trough will mostly remain over the Gulf. However, modest vertical shear with effective shear magnitudes around 25-30 kt is forecast. Furthermore, elongated/straight hodographs are present in forecast soundings across portions of MS/AL. Boundary layer moisture will be modest (upper 50s to low 60s F), but cold temperatures aloft will support steep midlevel lapse rates and contribute to 500-1000 J/kg MLCAPE. Overall, this environment may support isolated strong to severe storms, with marginally severe hail and gusty winds being the main potential hazards through the afternoon. ..Leitman.. 03/11/2025 $$
