Widely scattered severe storms capable of mainly damaging wind gusts appear possible over south-central South Dakota into central Nebraska Thursday afternoon and evening. More sporadic occurrences of mainly damaging wind appear possible from the northern High Plains into the upper Mississippi Valley into the central Plains, the Raton Mesa vicinity, and the central and eastern Gulf Coast. ...Central to northern Plains... A midlevel wave is forecast to move across the northern Plains Thursday morning, with areas of thunderstorms likely ongoing from the Dakotas into eastern NE and KS. Aiding this activity will be theta-e advection out of the south, with the 850 mb gradient aligned roughly along the MO River. While some of the region will be locally stabilized by this activity, a corridor of strong heating/recovery will occur near the surface trough during the afternoon, with renewed activity over central SD into NE. Substantial storm coverage will likely lead to mergers and an eventual MCS moving southeastward into the evening. Sporadic hail may occur with the afternoon/initial cells before transitioning to mainly a damaging wind threat. ...Southern AL/GA into northern FL... A surface trough will remain draped across southern GA and AL with mid 70s F dewpoints to the south. A weak northwest flow regime will also remain over the area as the upper trough over the Northeast slowly departs. Strong daytime heating will lead to substantial instability, with scattered storms developing along the boundary. Given the high PWAT and steep low-level lapse rates, some of the cells are expected to produce locally damaging gusts. ..Jewell.. 07/29/2026 $$
