Significant Tornado Events

[CheeselandSkies]

wow! other than a few point-camera-at-tv recordings and tiny snippets, this highly-sought after full coverage has remained nonexistent until today.

As someone who works in local TV news, it should be known (and this may surprise some people) that TV stations aren't always recording their own air streams. We simply don't have enough storage capacity to do it, especially with a total of six channels over-the-air (our main channel with our NBC affiliation, and five subchannels).

We have a service that records web streams of all the channels that are kept for several days, primarily for reviewing what happened during any technical problems (so clients don't get billed for commercials that didn't actually air, for example). We can clip and save footage from these but the process is tedious and the quality isn't great.

We do have recordings set up to roll on all of our newscasts in-house, but anything such as long-form severe weather coverage that airs outside of normal newscast timeframes won't be captured unless someone remembers to manually start a recording when it begins; and sets it up to run long enough for the duration of the coverage (the default on our system is one hour).

thank you for the incredible insight as always. i just assumed tv stations archived it all (foolishly thinking that it could be stored digitally with ease, but of course, storage isn’t endless) but this explains a lot!

Bit of an off topic question but am wondering what some of you guys think on the official start point of the 2013 Moore tornado? Have a full contour map in the works and for the life of me can’t fully decide or make out the start point of the tornado. I have the most consistent damage beginning near a pond just south of Long Drive, or about 3/4 mile south of Highway 37 south of this general area photographed:


The issue is there is notable damage that can be traced back to near Timberlake Reservoir and I guess what you can call somewhat convergent tree damage as well, however video evidence shows the funnel becoming more defined and touching down closer to Highway 37 despite that damage. I’m very meticulous in these maps if you couldn’t tell lol but I’d love to get some opinions before I drive myself crazy.

The starting point near Long Dr. is probably pretty accurate given what we know. Entirely possible there were brief spin-ups preceding it, but there's nothing in the damage pattern, radar signature, visual presentation, etc. that definitively points to an earlier touchdown IMO. That's why I kinda like Fujita's approach of using a broken line to indicate a funnel aloft w/light damage that may or may not be tornadic in nature (Brandenburg or Elizabethtown, for example):

That’s the highest quality shot of his 74’ map I’ve ever saw. Can you actually purchase those anywhere?

Not sure, but here's the full version of the one I have:

Yeah I agree, really analyzing aerial imagery and damage points there are several gaps and you can’t really draw one continuous line. Might just mark down each damage spot either way and count it as brief little spinups.

Not sure, but here's the full version of the one I have:

Fascinated with what happened with Guin and Huntsville...almost like a merger/semi-occlusion occurred while passing over the Wheeler Lake/Tennessee River area. Weird how Guin's path begins and ends with multiple spin-ups by an aloft funnel or something of the like, and how Huntsville had 2 circulations passing through it (remnants of Guin and the Huntsville tornado). I wonder if what happened there is also what happened with Hackleburg/Huntland in 2011. Originally Guin had a path length of ~130 miles before it was corrected to being 2 separate tornadoes, like with Hackleburg.

Yeah, not totally sure what's going on there tbh. I know it cycled super quickly (Huntsville was on the ground within a couple minutes of Guin lifting) but I dunno what the continuation of the original circulation aloft is based on.

Maybe straight-line wind damage?

I think a lot of those dotted sections are guesses, inference, mistakes of straight line winds and even a bit of wishful thinking. Don't forget in that era the idea that tornadoes 'skipped' was still prevalent.

Back when the old LandSat viewer existed it had a couple of filters that were far better for tornado paths than the new viewer. And it's pretty clear that the official starting point of the Guin tornado between Vernon and Sulligent is the correct one, not the extensions back into Mississippi.

Yeah, there doesn't seem to be a ton of consistency in how they're used or what they're based on.

Re: the start of the path, I think the imagery from 4/29/74 shows it best. Most of the track is pretty visible as-is, but playing around with it a bit in Photoshop makes it super obvious (arrow marks Sulligent for reference):

Today is the 4 years anniversary since the Linwood, Kansas EF4 tornado and Waldo, Kansas tornadoes

Somehow, the Waldo, Kansas tornadoes were poorly surveyed that only one tornado managed to make it into the survey and was rated as EF2

I've watched this video several times. I don't know its location, but if I had to guess, it might be from one of the homes on the southern end of town in the fields on the East side of Hwy 25 where it entered the city. You can see one home that is destroyed in the foreground. I'm guessing this is the location because you can see the trees lining the West side of Lock Dam B and Lake on the Left side of the video. At this point, I think it's going through town, or it has left town and beginning its trip through Southern Itawamba County. You can hear the person spitting what sounds like some installation from the destruction of their home. It's pretty sad to me.

I wish I knew where this picture was taken. I know it's outside town, but I wonder where.

That was taken at Cedar Ridge Drive after the tornado had exited the town.

It's the 10th anniversary of the 2013 El Reno, OK EF3-EF5 (depending on who you ask) which is infamous for being the first known instance in which experienced chasers (Tim Samaras, Paul Samaras, and Carl Young) died as a direct result of being impacted by the tornado.

Unfortunately, given what we've seen in reason years, it would seem the lessons from this day have not stuck among certain sectors of the chase community.
