First identified in 2009, these things are being investigated as the first new type of cloud to be recognized since 1951.

I took these photos with my iPhone when driving from my office in Aurora, MO to the courthouse in Mt. Vernon, MO between 0840 and 0855. Photo 1 was taken in downtown Aurora around 0840, 2-5 were taken on Highway K just north of city limits around 0845, and 6-9 were taken about five minutes later on Rte FF around 0850 after the weird "roll" cloud had passed.
Considering that I was driving at the time, the camera did a great job IMHO. The first one was taken at a dead stop, the others were sideways shots at 40-60mph.
