6/2/2005-----Tornado? ***Large Picture Size***

Here are a few images from my 6/2/05 chase in Arriba, CO outside of Limon, there was a large tornado reported on the ground at our location when these photographs were taken. Originally I didnt think I saw anything other than some nice close rotation in these pictures, but upon further review I cant tell if there is possibly a little rain wrapped something under the meso. Any thoughts on this would be much appreciated!

Yeah, I guessed it was a false report. We were exactly 1 mile north of Arriba when reports of a large and destructive tornado on the ground 1 mile north of arriba started coming in over the radio. We pretty much figured they were false when we didnt see anything or get killed. However, and it's likely just my eyes or mind playing tricks on me, I cant figure out for the life of me what that darker "column-ish" thing is under the rotation. Maybe it would help if my real camera hadnt broken and I was stuck using a 1 megapixel camera at the time. Oh well, C'est la vie.
 
Hi,

Now that is interesting - so there was no tornado in it's entire history? I know in my unclear footage from the south rapid rain turning and what seems to be a large tornado but in both video footage you cannot make it out definitely. So that probably explains it. We were located further east of 30 miles or so from Limon. I was told by chasers who believe they saw a tornado further east from us looking into the notch. Whether there are any photographs video I have not seen any so cannot confirm.

Regards,

Jimmy Deguara
 
Nope, no REAL tornadoes... I know quite a few chasers that were on that storm. When the report came in, I wasn't really surprised to see the report of a big tornado - because the storm was an absolute monster on radar. Yet, as soon as I started to talk with other chasers from the day... They all said they saw nothing in the way of tornadoes. I believe it was Scott Webberpal who was VERY close to the location of the "tornado" report, and he said himself it was falsed.

Mike Hollingshead, Amos Magliocco, Eric Nguyen, Scott Webberpal, Pete McConnell and dozens of other chasers were on that storm - no tornadoes.
 
Actually, I was chasing with Scott Weberpal that day. So those pics are from right there. Dont get me wrong Nick, I completely agree with you...no confirmed tornadoes from those storms. Maybe I should change my thread title, because I more want to know what the darker column-ish thing is, as it caught my eye when I was reviewing my pictures.

If I remember correctly, the first three in that list were mostly getting structure shots, so they probably wouldn't have been in position to obtain pictures of any tornadoes that were wrapped in rain.

Actually, Amos himself said that Dave Fick documented a small cone tornado. http://www.cycloneroad.com/2005june2.htm

Looking back on some chase logs, there seem to have been two seperate apparent tornado sightings. The large rain wrapped one and the small white cone tornado. Doesnt jive with the report of no confirmed tornadoes, especially if there is video. Dont really know what to think about the event. Anyways, I'm gonna call the denver office and ask about any damage surveys they did.

Andrew, I'm sure Shane is well aware of that and was just being a bit facetious. This thread reminds me of Jaws 2 when Chief Brody has that dark picture of he shark's eye and no one sees it but him. Seems impossible to distinguish anything from these photos.
 
I ran these photos through some really heavy enhancements, which means they aren't entirely accurate:

Your imagination could run wild with that first photo. However, I think the second clearly says precip core, made darker by the storm base. There even appears to be a downburst swirl on the right side of the photo.

No, I was being very serious. All I see are giant black squares in those top images. I can't make out anything. I can barely see the bottom ones, enough to say IMO that isn't a tornado. The bottom one looks outflowish to me, perhaps the storm was cycling at that point?
 
Just wanted to thank you guys, Nick et al. for taking a look and giving your opinions on the matter. It was an amazing day for a "first" chase and one that I wont ever get. Skip, those enhancements are awesome...how did you make them?

Either Paint Shop Pro or Photoshop will do the job. Personally, I prefer Paint Shop Pro to Adobe's cumbersome, unconventional interfaces.

1. Edge preseriving smooth. This filter smooths the noise while at the same time, identifying the edges in the image and not blurring them to oblivion. Without this smoothing process, the later contrast enhancements multiply the noise to a point where its too distracting to discern any features. This filter isnt perfect of course, and rain wrapped storm bases don't have razor sharp edges, so you will still lose some fine detail.

2. Contrast Enhancement. This can be done manually with curves or with an automatic filter. Mike H is a master of modifying the curves to really make an image "pop", but I just ran it through the automatic process on this one for reasons of time. You'll want to adjust the settings so that the area of interest is in the center of the greyscale range, and so that the brightest area of the image is almost white, and the darkest area almost black (for analysis purposes, not for show).

3. Paint Shop Pro's clarify effect. What this feature does is locally enhance the contrast as opposed to the contrast of the entire image. This is extremely handy for bringing out features in all areas of the image without oversaturating or wiping out entire sections. If you have yourself a rain wrapped tornado, and the camera is able to barely discern the edges, this filter will bring it right out. It doesn't look pretty at the harsh levels I took these images to, but its great for analysis purposes.

I was chasing that day with Pete McConnel and yes we did see a bonafide supercell tornado that was on the ground for several minutes. This was on the second more southern supercell. I know we were southwest of Burlington, CO. Now the first cell farther north put down a lot of RFD and little spins (which could have concievably been tornadoes but more likely gustandoes) but nothing very convicining.


RFD on first supercell causes several spin-ups and large dust cloud.

Spinner that occured for twenty seconds about 1000m away from RFD dust.



Distant picture of tornado SW of Burlington, CO after about three minutes of being on the ground. (My vidcaps are terribly out of focus but ask Pete and he has at least 2 minutes from a little debris cloud extending to the cloud base.)

Hope this helps!
Scott Olson.
 
Scott I have that same thing on video sw of Burlington. I couldn't decide what it was, but opted to not count it as a tornado. At first on video it looked like there was condensation above it in the form of a 'funnel', but a harder look and I could see it was just how the clouds lined up. There was a good deal of undercutting from the north and just figured it was more of a very low level spin up from that. Since you quoted Nick here with what I said I personally saw, I thouhgt I'd comment on this. I never said there was no tornado for sure, just that I personally never saw one. I was in terrible viewing contrast for a good while on my stupid navigating. There certainly could have been something before I got to it nw of Limon as well as just after Limon while I was se of it in poor contrast. But, the thing sw of Burlington I did see and did not count it as a tornado. Perhaps it was a legit supercell tornado, but from my perspective I figured I was less sure it was a tornado than I was that it was. When it is hard to say I think it best to just say it isn't. All in ones perspective I guess.

First, dis-regard my little vid capture of it as it is unrepresenative of what we saw. All I was pointing out was that from the vantage point of myself & Pete McConnel it clearly appeared to be a bona-fide supercell tornado which was first present with some low level rotation and debris and eventually extended well into the cloud base for several minutes with rotation evident the entire time. I wish Pete was a member on ST and he could post some better video or video grabs from this but we both have concured that the storm did indeed produce a tornado. I certainly can understand that if one cannot certainly discerin that it is a tornado to not count it as such ( I am the exact same way and have discounted several possible tornadoes when I could not visually verify or did not have the photographic evidence to support it). In our case we reviewed Pete's video and we were both reasonably convienced even before reviewing Pete's video because we viewed dust getting drawn into a circulation that extended into the cloud base.
