It may not have been the biggest, but dang it left a mark. In Enterprise, Al a EF3/EF4 tornado barreled through the heart of town destroying houses and hitting a school killing 8 or so students.

My view of it. I was watching the storm of GRLevel 3 in awe, knowing what was going on at the the surface as the tornado rolled through Enterprise and surrounding areas.

All in all, most likely 5 EF3's or greater touched down(including the Enterprise tornado) from MO to Ga, killing over 20 people and causing massive damage. With Spring Tornado season just starting I expect more of this type of damage and destruction to come.
It is also important to note, this is the first EF3 or greater to hit the Alabama in 5 years, and the first EF3 or greater to hit the state in 8 years during the Spring.
