Indeed it is.

Here’s a still image from the video. Not to beat an already dead horse, but there’s basically zero chance in my mind that the train car rolled or was dragged there. You can see the drag marks from the other heavier train cars going off track, that is indicative of the sort of movement the tweet was insinuating. And it definitely didn’t roll, you’d have impact marks on the land much deeper than what’s shown here. Grand Forks came to the right conclusion and that is that this thing was thrown.

Those other three tankers still strike me as being more impressive for some reason. It's the fact they were dragged sideways while still being hooked together. That's triple the weight even without the rolled over hopper car. They show drag marks but that just means intermittent contact because there’s gaps. Those were also partially lofted into the air for some part of it.

Plus the insane vegetation damage I posted too, just seals the deal.

Found this aerial of Enderlin that seals it as an EF5: youtu.be/ilfQat2RvrU. Two snippets are below. Note the absurd tree damage, especially in the top image.View attachment 47236

Post if interested. Bottom image shows farmstead #2 if it wasnt obvious.

It's wild how many tornadoes from 2011 could be upgraded to EF5 with the new tree DIs. Flat Rock is a prime example of this.

Ok finally had a look. Awesome stuff here!

Also yup, the one slab foundation house in Ringgold I always wondered about ended up being the one meeting EF5 criteria. NWS Peachtree City dismissed the allegations of EF5 damage in the Cherokee Valley area because of poor anchoring and weak foundations, and I admit I largely did as well. However, that one slab foundation home always stood out to me. I always thought that if the slab home had anchor bolts, it would completely invalidate the EF4 rating and the rationale behind it, but I never knew if bolts were present or not. Turns out that’s exactly the case.

After reading this, I’d say Ringgold not only meets the newer more liberal post-Enderlin approach to defining EF5 damage; it meets the older more stringent definition too. It should have been rated EF5 to begin with, and the fact that NWS Peachtree City rated the damage low-end EF4 is simply ridiculous. The only silver lining is that if NWS Peachtree City surveyed this tornado today with their current staff (the one that did the Newnan survey), the results would likely be VERY different. Gotta celebrate progress when you see it, even when it’s after the fact.

Thanks for gathering this information and posting it to the forum! It completely changes the way I view Ringgold and its rating.

For the opposite effect, The only two this decade EF4’s I'd consider downgrading to EF3 are Newnan Georgia and caviness Texas.
Newnan is obvious.

Caviness is just, well, It never had a violent look too me. None of the damage did. It seemed a bit generous but It is really borderline. EF4 is fine but it's on the edge. The Di home was just collapsed and slid off the foundation into a big pile. None of the debris seems very wind rowed.
Would anyone concurs on that or is it just me?

Call me crazy, but based on this image I think the train car mightve actually done a 3/4ths orbit around the core before it landed.

looks like a other tornado might get upgraded.

 

[tornado examiner]

I been wondering about spiritwood but the more time that goes on the more I doubt it will until the new EF-scale is officially published.

i was looking at the other tornadoes of this outbreak base on sat , and almost every other tornado except for one of the EF2 had major ground scouring , the most intense tornado base on the scour mark seems to be spiritwood , when it turnd west and was in its shrinking stage.
