Will Mid-Southerners be able to see it? Not likely - for two reasons. First, NASA indicates that a mid-size telescope (or better) will be required for backyard astronomers to view it. Not many of us have that type of instrumentation. Second, if you did, unfortunately the weather will likely not cooperate. A storm system arriving Tuesday night will be throwing a large amount of cloud cover over the Mid-South throughout the day Tuesday. Even with the proper telescope and the knowledge to use it, clouds will likely obscure the phenomena. We'll have to resort to seeing other's reports of it on the news!
