Yea. That's a good example of a really ominous looking non-tornadic cloud. Sometimes from a head-on perspective an inflow feeder will look like it's lowered vertically to the ground when it's actually tilted and descending at a shallow angle towards the horizon. An RFD shelf can also create an eerie wedge appearance in the distance when you're looking along it from a cross-section point of view instead of head-on.I was a noob in my 3rd year of chasing, and I was totally fooled into thinking this was a big tornado over Dodge City. Scud.
Your pictures should be part of every NWS spotter session. They show how easy it is to get fooled. (I'm too embarrassed to post the scud that hoodwinked me in my earlier days.
I'm inclined to agree with Marshall, it does look like convective rain-free base (a non-rotating wall cloud), likely from a developing multicellular storm. Unless it was rotating, in which case it was likely an isolated rotating wall cloud within a convective eddie; it is attached to the cloud base, so in theory it could absorb surface based vorticity and form a non-mesocyclone tornado
Are those striations not from rotation then? Scud clouds don't rotate and there are plenty of tornado reports from Western Kansas that day. Most chasers aren't meteorologists and don't always know what they're looking at, especially when you saw something they didn't. When I'm not sure what I saw I usually run it by an NWS meteorologist and/or a few local television meteorologists, and possibly a few spotters I trust, then use the consensus to determine what I saw. I'd be extremely curious to see that video if you still happen to have it.
Ah yes, but such inflow feeders can also be adjacent to a tornado, and could easily shroud one from the wrong angle as well, I personally think video is a far more reliable as it shows motion.Yea.

Now I'm REALLY curious to see your video! Would you mind doing a private upload and sharing it on this thread when you get home? There shouldn't really be any rotation at all in scud, sure, they can briefly swirl around eachother in a disorganized fashion now and then, but the discernment between scud and something threatening is rotation within the cloud (and not simply clouds caught in rotation), not to mention that NWS clearly defines scud as disconnected from the cloud base. Maybe you saw a developing shelf with scud inflow, but I'd be hard pressed to call that entire structure scud. . .As I remember it now, my chase had started around Liberal. Somewhere west of DDC, anyway. Because I didn't know what I was doing I ended up chasing the FFD region of the storm, which is what you see in my pics. I do have the video, but not with me. I'm not home. The video does not exhibit any rapid rotation. That scud may have been rotating slowly, but of course that is meaningless. It appeared to me to be right over DDC, not just nearby, so it was likely within 5 miles of the DDC radar, if not less, yet the mets at the office there never issued any warning. I have to believe they were looking at it right out their windows. There was no tornado reported there, no damage.
So bizarre! It almost looks like there might be weak rotation embedded in the left side of the lowering, however, I can concur the structure as a whole isn't rapidly rotating. I'd say that's most likely an inflow tail, but it could be a wall cloud with inflow pulling in from the right side. I don't mind the lack of audio, I love the footage for being nostalgic enough! haha 2001 the era of Stupidvideos and eBaum's World, not the best places to post storm chasing footage!Done, finally. I just got home Friday. I muted the audio because it features my old nowcaster's voice on a speaker, and I didn't want to bother taking the time or effort to try to reach out to ask his permission to put his voice on the internet. He used to be an ST regular, but I don't think I've seen anything from him in at least several years. Anyway, you really don't need to hear the audio.
First time ever this video has been on the internet. YouTube didn't exist in 2001!
