Severe weather threat 4/23/26 (Central/Southern Plains)

I am of firm belief Enid was a EF5 in terms of intensity but I don't think there is any real contextuals that would push it for the rating. This is just exceptional damage.

That third photo of the reply stood out to me. That is some extreme damage to low-lying vegetation.

Yeah, i don't know what I meant by there isn't any contextuals that would push it. That is extreme damage and clearly indicative of one of the more higher end tornadoes seen in Oklahoma in years.

Some easy geolocating was done on the KOCO footage, specifically where Amanda Benton captured a absolutely debris laden landscape from the tornado and a home sort of sucked in if I see it correctly. This was taken just south of this same subdivision.



1:44:37 for the shot I'm referring to. That is the most visually impressive shot I have ever seen on live coverage in my time of watching severe weather, and given the damage, this doesn't surprise me.
 
Surveyors actually ended up rating the two story slider house ef4, despite noting it to be not well attached to its CMU foundation, they used the contextuals around the house to justify the rating.
This is exactly how the ef scale is supposed to be used, find the reason why at tornado should be rated violent, instead of finding a reason why it shouldn’t be violent.

I know metal buildings are incapable of receiving an EF5 rating based on the confines of the scale, but if that image Nick Krasz posted has sheared bolts that were installed into the building with clearly obvious extreme contextuals surrounding it, do you think it’s possible this receives an EF5 rating, especially given the fact that LaDue and co. seem to be more open minded now with applying higher end ratings?

Very well done by NWS Norman. I always thought they should be the one to lead by example, being as they home the SPC and are the epicenter of tornadoes and severe weather.
 
Contextually speaking, that’s a definitive EF5 for Enid. That shredding of low lying shrubbery is absolutely insane. If they could find home damage that is anywhere near the expected threshold for EF5 (201>) they will rate it such. They’ve shown that if they find context to back up the idea, they’ll use it.

The metal building itself? No chance.
The contextuals? Not likely, even though the ground scouring is indeed upper echelon comparable to past ef5s, they can’t rate the tornado based on that.
Philadelphia from 2011 was a special case in which it did get rated ef5 purely by ground scouring, but the scouring was feet deep. Although I think that was a severe isolated case of trenching rather than scouring.
So yeah, no ef5 for Enid, honestly though Im completely fine with that, NWS Norman went above and beyond with this survey.

I believe you're thinking of Philadelphia, MS. Hackleburg-Phil Campbell had multiple instances of EF5 structural damage (at least, given the way the scale was interpreted at the time).
 
Metal Building System, EF4 170 MPH DI description:
New construction. Numerous anchor bolts sheared from slab. Extensive ground scouring. Part of shop beam buried by scoured mud. Most of the structure lofted into the field (we think that’s it). 15k lb RV was parked in this building and cannot be found. RV owner walked onto hilltop in field and could not find it.
Good lord.

If they can locate it, maybe they can do what they did with Enderlin. Lol

I was able to find it on Vexcel aerial imagery; it was ripped down to the frame and lofted into a field east of the home.
