Yeah, 4/27/11 was probably more similar to 3/21/32 or 4/20/1920, as those outbreaks had tightly packed, narrow areas that became more or less Armageddon. I know those outbreaks aren't as well documented but it wouldn't surprise me if they had a similar amount of tornadoes that just didn't get recorded due to the lack of technology compared to now.
I don't know where this was discussed on the thread before (or any other thread on the site) but I believe it was, we'd have to dig through tons of pages to find it though lol.
3/16/1942 and 3/28/1920 affected particularly large geographic areas
I think you meant Palm Sunday 3/28/1920. Dixie 1908 and May 1917, 1896, 2003 and 2019 sequences were far reaching. Veteran's Day 2002 and Nov. 1992 fit the bill, too.
its to note for cullman it was not when it was at cullman but later on , it did also dug some trenches , for now i am able to keep vilonia/chickasha/goldsby out of the EF5 group (but barely , all at the 200 mph mark group) unless theres info that i didnt put about them yet
Search "Vilonia" with Marshall's username in the search bar. Then the same but with Ponhpei's. Then you will see why Vilonia should make the list.
Those events and 5/9/27 immediately come to mind as far as huge areal extent, though obviously none of them came close to the ridiculous intensity of 4/3/74. IIRC, 4/18/1880 covered a large area as well. You could add more if you include outbreak sequences, but I tend not to for this sort of thing.
Palm Sunday '65 didn't have a huge number of tornadoes overall, which is what keeps it from generally being considered a Super Outbreak. I kinda go back and forth on that personally.
ya but it seem to had more tornadoes then the 1932 superoutbreak (apparently listed as one)
I'd imagine the numbers are pretty significantly undercounted. While I was researching the Tupelo-Gainesville outbreak I found at least half a dozen undocumented tornadoes, and I wasn't even specifically looking for them. That said, I'm not certain I'd consider 3/21/32 a super outbreak either. The Enigma outbreak is probably at least as good a candidate, though it's hard to say when there's so little verifiable data.
I'm sure lots of the Dixie outbreaks from pre-1950 likely have dozens of undocumented tornadoes, majority minor but probably some violent ones that stayed out in isolated, backwoods-type areas that were likely even more remote back then compared to nowadays.
for death (ignoring Joplin) , we have been doing honestly pretty good compared to the past , 2011 super outbreak and the Mayfield tornado kind of came close but its not as bad as it was in the past or Joplin
There has been a consistent downtrend in tornado related deaths even as urban areas expand and the population of the US increases so I don’t think it will uptrend any time soon.
For the "trenches" , I actually have hesitation about the trenches digging automatically EF5 qualifier thing. The recent EF3 tornado in La 11/29 dug pretty remarkable trench near an EF2 rating house and I didn't see anyone said it was an EF5 level tornado. Also there was an EF1 tornado dug considerable trench. Despite the fact that the rating could be higher if it hit something significant but clearly it wasn't anyway close to EF5 level tornado. So I think trench digging was never classified as an serious DI in both F and EF scale and won't be in the future revised EF scale for a reason. The mechanism behind this phenomenon is still largely unknown and should be discussed and detected for every specific case. Nelson once had some pretty good discussion about this phenomenon and I'm gradually convinced that in many cases, it doesn't need specifically high winds to dig a trench and it is more of a matter of soil condition in most cases. Also considering the fact that the definition of tornado winds in EF scale was 3s winds, I tend to think that it shouldn't be regarded as automatic EF5 qualifer.
i mostly agree with your reason but , there is a depth point we can agree would be EF5. the EF3 trench digging was not rated EF3 but EF2 , however i feel it might fit more with a EF3 rating for that spot.
not finish but hey at least even not finish there all in equal footing.
There was a Twitter thread recently from a soil scientist that got into this. I don't have it handy right now so I'm going from memory, but IIRC his suggestion was essentially that there were two different strata of soil with different properties and that the top layer sort of separated at that boundary. Once it started getting pulled up (maybe from a debris impact or just some kind of existing discontinuity) it basically peeled away in strips like fresh sod.
I’m surprised that Sherman is up so high on that list with the little information that exists about it. Also why do you have Jarrell as an F5+.
