Discussion of April 27, 2011 Outbreak

This from IEM. Exclusive to TOR-Es and FFEs as far as I'm aware.
Yeah found it. I hope IEM make some sort of radar archive where you could access velocity + CC and you can just review a big radar archive of previous days. The amount of TOREs covering that area, just wow


It's incredible that 4/15 and 4/16 are completely forgotten. They were very intense outbreaks and any other year would've been the headliners. But 4/27 blew the meaning of historic out of the water
 
it went from this:

In one singular scan. Notice how it had hit Smithville between scans; by the time it was TOR-E'd it would've likely already been out of town.
I do understand why they didn't issue a TORE because of these reasons, but I can't say I agree with said reasons. The storm was in a absolutely maxed out environment, and also was on the outflow boundary. Like you said, Smithville formed and intensified to EF5 between scans, making it a difficult call on whether or not it should be given an emergency tag. I would like to think that many other offices would've pulled the trigger on it that weren't MEG, and it would have been the right call. Hindsight is 20/20 though. I will say I don't think it's as clear-cut as many make it out to be, but I do ultimately think they should have issued an emergency in the moment and risked being wrong simply because the environment the cell was acting upon was so extraordinary.
The radar presentation on the Ringgold storm was horrible, so I get why that one didn't get the emergency tag:
Forgive me if I'm wrong on this, but doesn't this more have to do with the radar holes at the time, issues with the radars themselves, and less with the actual appearance of the storm? I find it particularly difficult to believe that any storm really looked like "trash" on this day. I know while it produced the Rainsville tornado it also still looked a little odd (had a BWER on it though). Regardless, I can see what you mean here too.

It's also worth noting that the 4/15 Moundville EF3 was given a TOR-E:

Tuscaloosa (or at least part of it) was under a TOR-E twice in twelve days.

Yes, I'm pretty sure that north GA corridor was in a radar hole in April 2011. I moreso mean that the radar did not give an accurate presentation of the supercell, and thus the NWS may have not properly seen the rotation. Looking at the image I don't even see inbound velocities, let alone a violent tornado. I'll put up the LSR page later; there might not have been spotter confirmation it was down due to how dark and messy it was while in Ringgold.

I could see this being the case. I mean, nothing like that tornado had ever been observed since the first usage of the TOR-E in 1999. I will say, though, that I don't think MEG should be faulted for it - in the end, even if it had been issued the second that debris ball scan went out, the same amount of lives likely would've been lost. Usually I'm a believer in the fact that TOR-Es save lives but that one wouldn't have been sent out in time, unless it had been TOR-E'd back near Amory. Overall I think every office that day tried their best, and some were just completely overwhelmed.

I actually think the poor radar presentation of Ringgold, and to some extent Rainsville, was a combination of it being in a hole plus hytop radar going down and losing power after Hackleburg severed the lines from Browns Ferry nuclear plant. I imagine the Ringgold supercell, if you had a clear look at it, was wrapped up like a top like all the storms that day. You were essentially looking at the cell not from the nearest radar because it went down.

That parent storm put down tornados all the way up into Virginia into the night, so it was still an absolute monster when it left Alabama.

Edit: looking at this now, Ringgold would have to have been viewed from either FFC or BMX, which is a very long distance.

Highly unpopular take (I'm full of those) but I can actually understand the fundamentals of why a tornado emergency wasn't issued for Smithville. It's very similar to Joplin in that the structure highly intensified over a very few number of scans, and they were already dealing with so many warnings that they might not have had time to discuss TOR-Eing that one. Pretty sure it was caught in the Hamilton-area TORE once it crossed into AL, though. I mean, it went from this:

On the flipside you could argue that they should've TOR-E'd the parent storm as far back as the Houston area, when the Okolona EF3 was on the ground:

I could see that being the case if MEG didn't play conservative on 4/27.

As for Georgia, of all the ones I think should've been TOR-E'd it has to be Barnesville:

Oof yeah, didn't remember the radar hole but yeah I don't think you get a TORE out of a presentation that sh!tty unless actual, TRUSTWORTHY (Glares at Arkansas 2022) spotter evidence of a vio is relayed to the office.

I mean, KFFC is a long way away, so that enhanced velocity signature is about all you’re getting unfortunately. But there were a lot of reports from LE and spotters on that tornado just SW of Ringgold. Now whether those reports were submitted as LSRs, that’s another story as it was a hectic day for most WFOs.
 
I've always said that April 14-16 would have been remembered as a legendary outbreak if it had happened in any other year, probably at least as well known as Super Tuesday 2008. And as bad as it was, one thing that I think about a fair bit is how much worse 4/15 could have been, with it really being only the messiness of the morning round of storms that put a damper on the setup.

Just imagine having two super outbreaks in the space of 12 days.
It’s still the 2nd largest outbreak in Alabama history. Which is wild.

I’d be surprised it wasn’t 4/3/1974, but then you realize that most of the AL tornadoes that day were non-cyclic (iirc) and very long-tracked, so while there weren’t that many a lot of them were exceedingly violent.

Also, is that Ohatchee in your profile picture? I’ve always found that tornado very interesting due to the possible terrain-based influence that happened.

There are probably some cycles that are counted as one tornado due to surveying methods of the time. Heck, even for the 2011 event, reanalysis of the "longest tracked" tornado of the day (Hackleburg) has led to it becoming widely accepted that it was actually two tornadoes.

True, I didn’t think about that.

True. That said, Tornado Talk sided with the longer path length of Guin, and I haven't seen any suggestion that Jasper was more than one tornado, so perhaps there were legit long trackers that night?

You’re absolutely right about ‘74. I do think the 1932 event had more than the 15 or so tornadoes, but it still doesn’t get close to either April 2011 event.

Yes! This is right after it made the turn into Shoal Creek Valley and began destroying those small towns. To me, it’s the forgotten monster from that day.

IMO, I don’t see anything wrong with the track lengths for 4/3/74 in Alabama. Perhaps one or two were a tornado family, but the tracks are consistent with previous events with significant long track tornadoes to include 4/27/11. Even if you double the tornado count from 1974, you would barely crack the Alabama single day tornado top 10, which is crazy.

That tornado was a demon in terms of where it hit:
1772033089013.png
It ran just parallel to Shoal Creek Road while near peak intensity; if I remember correctly many of the deaths were on this one road.

It's crazy that you can directly make out the path of the Cullman, Yantley, Tuscaloosa, Cordova, Higdon and Lake Martin EF4s, as well as the Eoline and Huntland EF3s based solely on the TOREs issued. Wild day.
yup, still holds the record for most tor-es active for a single day, I hope to never have to track something of this caliber in my lifetime

still wild that Rainsville got tor-e'd, I think due to the rather impressive signature from the BMH radar as HTVs radar ended up going down

I'm a little surprised too. From the Peachtree City radar. Also, am I going insane, or are there two very well-defined circulations at once on the velocity scan?
 
IIRC there have been occasional instances of people uploading videos of even older weather events (e.g. the 04/26/1991 outbreak) online even to this day. I can't help but wonder how many images/videos of various events (not just weather events, either) are currently gathering dust in various storage spaces that could use some uploading to the Internet instead...
Yeah and same
