Ma-Ma-Mammatus!

I have seen larger and more pronounced "globules" and sunlit displays before, but never have I seen the entire sky filled with spectacularly brilliant mammatus formations. In fact, I would consider this spectacle nearly a once-in-a-lifetime event! The mammatus display was the culmination of an afternoon and evening that produced severe weather, including tornadoes, in southern and eastern Iowa. This was also the culmination of a storm chase my daughter and I took part in the aforementioned SE Iowa area earlier. The images were captured at the Culver's restaurant in Hiawatha, Iowa--our post chase meal location--on Saturday, June 20, 2015.  The top image is a three image stitch panorama looking north. The middle image is the same image save one stitch. The bottom image looks west toward North Center Point Road. All images were shot at 8:47 pm CDT. Nikon D5000 DSLR camera.
