Also I have posted a Hesston, Kansas tornado several times and I think it picked up a 10,000+ square foot building as seen in the vid. Here is the vid again. It is around 2:34 in the vid.

For such a famous tornado, it is so hard to find a complete aerial damage photo of the whole town which is a little weird to me.

I know I can't find a lot of damage photos either. I will continue to look.

There was a pic on the old threat of people standing on top of an empty foundation that appeared to have well-spaced anchor bolts on the foundation, and apparently this was the one pic that made Grazulis think it should've been an F5, but I'm having a hard time finding it via google images.
I believe this is the picture you are looking for.

The EF3 tornado occured on May 9 2015 Cisco TX was very likely a violent tornado if it hit something at its peak intensity. Besides these pics below showed, NCDC database also mentioned:"Two cars, one tractor, and several farm implements were tossed over one mile to the east with this tornado".

This video showed very impressive rotation of this tornado

Lousiville MS EF4 in 2014 always considered being overshadowed by Vilonia's ferocity the day before. When the tornado reached its peak intensity, It debarked the entire woods alone Hartness Rd even the lowest one which can compare to some of the worst tree damage in dixie area(note the potential ground souring), then it swept away some MBS building and two large newly built brick house. To me, it was at least an high end EF4 tornado especially considering these contexual damage, it actually didn't hit much at peak intensity.

The context of this tornado should have gotten it rated higher.

I had never seen that video. Reminds of the Wynnewood, OK storm. Crazy motion, looks like was definitely capable of EF5 damage at some point.

The Wynnewood, OK EF4 tornado on May 9, 2016 was really scary. I wonder how fast that crazy tornado was rotating. It looked like a big cone/stovepipe tornado. There was also another tornado that day that was 1.8 miles--wide and was possibly capable of EF5 damage.

It looks like most of that brick house was swept away. I would myself place it at high-end EF4 with winds around 200 mph as it looks like borderline EF5 damage.

Agree with both sentiments. Cisco was rate low-end EF3 which is completely ridiculous. NWS Dallas is one of the problem offices when it comes to underrating tornadoes. Should have been rated EF4.

I also agree that Louisville should have been rated high-end EF4. I think the Vilonia debacle from the previous day caused some "La Plata" syndrome behavior at the NWS Jackson office. They were objective and middle of the road with their ratings until that very day, and I think it made them second-guess themselves unreasonably conservative for a few years after. They seem to be back to where they were prior to Vilonia as of this year though. I'm glad that mess didn't permanently affect them.

This is the damage from Ringgold that, to me, should have been rated EF5.View attachment 3603
I don't agree with your guys' sentiments about Ringgold at all. These homes were rather frail and not properly anchored, and shrubbery along the foundation perimeter was largely unscathed. This was specifically mentioned in an AMS video presentation. A clean sweep does not automatically equal EF5. High EF4 was totally fine.

I think the reputation for potential EF5 was largely the result of knee-jerk group think when the first damage photos came out. Once the info on construction became available, the idea of an EF5 upgrade sounded less appropriate.

I never have been sure how to feel about the Ringgold, GA tornado. It seems like borderline EF4/EF5 damage.

Most of the homes were block foundation, and all lacked anchor bolts and were of straight-nail construction. Not to mention that trees in this subdivision only sustained partial debarking, and low-lying shrubbery was left intact. I'm not sure how that's borderline. Anchoring, or there lack of, is critical when in comes to the final rating

I thought the EF4 rating was fair. The Ringgold tornado may have reached EF5 intensity in some areas when there were no structures to damage.

People always hone in on Tuscaloosa and Ringgold when in comes to controversial ratings from 4/27 and I don't understand it. There just aren't any pics that show clear cut EF5 damage, and as I said, I suspect that the controversy comes as a result of online group-think/mob mentality without any objective examination of the evidence available. Everyone's entitled to their opinion though...

The one that deserves a second look in my opinion, was the Shoal Creek-Ohatchee, AL EF4. This one swept away at least one anchor-bolted home with only the basement left behind, and aerial photos (which I have since lost unfortunately) showed considerable ground scouring near the 5W Ranch. An Ohatchee local on this forum who surveyed the damage from this tornado, also apparently found some pavement scouring as well. That all paints a more controversial picture than Tuscaloosa OR Ringgold.

I am starting to question the F5 rating for the Hesston, KS tornado on March 13, 1990. While the video of the tornado was impressive I can't find any damage photos that are really suggestive of an F5 tornado. I could be wrong though. How do you feel about this tornado Buckeye?

Talking about Katie–Wynnewood EF4 tornado, besides the car damage, EF4 house damage on NWS website, low level shrub debarking and potential asphalt souring in Basehunters's video, the ground souring as well as some debris loading pattern of this tornado was remarkable. I guess if it strike a town at its peak, it would be ugly. In terms of Sulphur tornado, I can't find anything clearly violent but the DOW7/RaxPol reading at near ground level says everything.

The Katie/Wynnewood tornado very likely had EF5 potential.

F4. I have seen pics of homes swept away by this tornado, but they appear to lack anchor bolts.
