The type of atmosphere today can be seen with the horizontal funnels rising up the outside of the tornado. Shear/helicity just incredible...

Yeah seeing that multiple times on different tornadoes in different parts of Alabama. Really unbelievable.

Just read through everything since this morning. Absolutely unreal. Today will go down in history.

Early reports can be hard to gauge but I think it's pretty clear that this is bad. One thing that might keep it from reaching Super Outbreak type status is that today is concentrated in a much smaller area in terms of strong/violent tornadoes (at least up to this point). 4/3/74 had them over an extremely large swath.

That's....I've never seen anything like that before. The detail....the updrafts and vorticity is incredible. And all of those power flashes...

look up some of the Andover Kansas tornado videos from 1991-very very similar to this. Everything I have seen of this in Tuscaloosa makes me think of the Andover tornado. Now when it was that monster moving into Birmingham, I don't know what I have seen that looked like that.

Will give Xenia 74 a bit of credit too. Certainly historic and going to be way up there.
