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.
