Heavy rain is likely across portions of the South next week.
We briefly touched on the overall the setup for next week in this update from Wednesday. A ridge anchored over the Southeast; deepening trough pivoting into the Rockies; active subtropical jet stream/storm track; and stationary frontal boundary at the surface will work to pump moisture into the Deep South for the duration of next week.
This will allow for multiple waves of thunderstorms and excessive rain starting Tuesday. As things stand right now, it looks like the axis of heaviest rain will be from central Mississippi into northern Alabama and Southern Appalachians (see figure 1).
Flooding issues are going to be a real possibility. We are also continuing to monitor for severe potential. However, currently it appears any severe threat will be rather low.
