Bit More On What's North Of Kitt Peak

From Carl Cerniglia, who is at the NWS Office here in Tucson: 

When I first saw this image 4:42pm, I said to myself "I've seen that before" but it was just SE of Seattle. We determined that it was a non-tornadic feature (the Seattle case) but yet it looked like it would have had a slow rotation associated with it, a Miso-low? This event occurred a few miles southeast of Seattle about 10 years ago (wow, time flys!) and the first image of the Kitt Peak event reminded me of this one.
