Airliners bound from Atlanta to Dallas, have been rerouted as far north as Missouri, and as far west as Waco, because of storms in TX, AR, and LA. It’s been interesting to watch.
Aircraft are holding around IAH until the storm passes.
Ahhhh…TMU working their majic… 
You can find airports which have possible re-routes or holds at fly.faa.gov/ois/ and from that link under Planning Team → Current Reroutes on the left-hand menu.
