I believe you as I only made the comment cause honestly I don't know as much about it as the other tornadoes of the day. But do you have a source for it being longer?

Nope, it cycled multiple times on radar with clear associated gaps on satellite; classic example of a rapid-cyclic supercell. 4/27 had multiple, including Smithville. When evaluating the track length TornadoTalk never indicates that they factored in the possibility of a cycle, which is evident by their (probably-wrong) non-stop length.

Hackleburg aerials I recently stumbled upon:

Alright, I promise I'll shut up about 4/27 but one last thing - BMX emailed me back and confirmed that they will not be doing a 4/27 re-analysis this year. So all tornadoes in that WFO (excluding Cordova, which was briefly in HUN at EF4+ intensity) will remain as rated for at least this year.

wtf?
Okay, so.....like....
...what about Cordova?
Are we really about to find evidence deconfirming every single long track tornado of the past 30 years?

Cordova is very solid, with a continuous track per GeoDESY. The only break is just before Cordova but we have video evidence it was down at that point in addition to radar not showing any cyclic patten. Cycles on radar with corresponding breaks in damage are very good indicators that a meso handoff took place and a new tornado formed. I can make a list of ones that are likely multiple if you want.
4/27 was the event of our time, and this is exactly what this thread is for, no need to stop.
Besides Enterprise, did you find any possible breaks in Shoal Creek/Ohatchee’s path? While not the longest tracked, it still went for 90 miles in the rugged terrain in East Alabama.
I think Hackleburg is still comically long tracked even with the Tennessee portion trimmed. It is funny though that even with out modern tech we still end up combining tornado families.
To be fair, I don't think that the surveyors on 4/27 had the luxury of going in-depth with their damage surveys. To bring up the obvious example, if surveyors made it to the worst of New Wren's damage, that tornado would have definitely been rated higher than an EF3.
While some of the lackluster surveying can be dismissed, New Wren was a humongous botch that's legitimately worse than even Vilonia's rating. Only reason it isn't talked about is cause not that many people know about it.
If it was any office other than MEG, I would buy that. That office, it seems systematically, has been awful at surveying for as long as I can remember. They have some absolute baffling ones.

Nick Krasznavolgyi recently announced he'll be doing a research post on New Wren. Interestingly, his Twitter following seems to have anti-weenies for lack of a better term. That is, people who say New Wren was probably "low end" EF4.
I don't think low end EF4s would toss poor Lynn Davis's truck 1.7 miles.

Speaking of Nick, would you guys like ANOTHER 2011 EF5 candidate??
Pocahontas is a ridiculous event but I am disappointed that the idea that it was a satellite may be false. Made it a really intriguing event.

Oddly enough this may count as a "mesocyclonic satellite" - an entire separate mesocyclone orbiting a larger one, like a satellite tornado but higher up. Would potentially help explain why this one got nommed by the EF3.
EDIT: Nick may also be jumping the gun on the tornado's nature, as radar coverage in the area was subpar and thus may end up with "warped" radar images, kinda like Rainsville when that area's radar bit the dust.
I'm game. What's the list?

- Jarrell, TX F5
- Parkersburg, IA EF5
- Yazoo City, MS EF4
- Cullman, AL EF4
- Enterprise, MS EF4
- Sawyerville, AL EF3 (borderline case; evidence of lifting but not a ton of evidence of a cycle)

The one here I’m most interested to see is Jarrel. Is that because the transition from rope to wedge is actually two different tornadoes?

...Cullman? Nani?

Cullman was three, with a short-lived undocumented tornado near Crane Hill shortly before (I actually have a photo of the parent wall cloud) and a third tornado just after the Tennessee River. Joshoct16 has a really good writeup on it somewhere. The vast majority of the track was one tornado, so don’t be fooled into thinking it randomly cycled halfway through its path. The main one also had numerous undocumented satellites.
