I read a survey a while back that noted that Shreveport is the most tornado prone area of Louisiana. In fact, I want to say that it labelled Barksdale as the single hotspot. The only real classic plains style low precip rotating wall cloud I have seen in my life I witnessed on the way over to Monroe from Ruston in college. That storm had dropped a tornado several minutes prior that killed at least 2 people. Still, north Louisiana is between classic tornado alley and Dixie alley which starts to ramp up near the MS river. The lone F5 in Louisiana history hit near the MS river and traveled into MS.
Marine layer protects those of us in deep south Louisiana most severe weather, save a rare occurrence like the April 24, 1908 tornado that hit Amite and Purvis, MS. Still ... Enterprise AL, Hattiesburg MS and Bassfield MS were all violent tornadoes within the last decade or so that are much closer to the coast than the historical record indicates is normal.
