Mammatus? Well, Close.

A line of showers was approaching the Cedar Rapids, Iowa metro area on the afternoon of Wednesday, November 13, 2024, and there were turbulent winds aloft associated with it. The above view, looking northwest from the Interstate 380 off-ramp at Boyson Road in Hiawatha, Iowa at 3:06 pm CST, shows the approaching quasi-mammatus clouds over a construction site located there. iPhone 11 camera.

3:32 pm. Looking west from Bowman Woods Park in Cedar Rapids.

3:37 pm. Another view looking west. The spine-like formations reminded me of a giant trilobite fossil in the sky!

3:39 pm. Looking north. The clouds in this area are very turbulent. Not what you usually see in the skies of Iowa in November! Nikon Z6ii camera.
