Altocumulus Undulatus
Classical undulating altocumuli sweep high above the Nebraska Panhandle. This set of undulatus was not as laminar as many, and might be considered a hybrid with castellanus because of the distinct convective elements riding atop some of the bands. Although we were on the way from a great South Dakota chase the day before to a date of destiny with some Kansas tornadoes the next day, the striking beauty and clarity of these clouds made me stop and get out to watch. The ebb and flow of translucence in the cloud bases, and the rich textures of both light and shape, then captivated me enough to make me stay awhile, as this armada of cloud bands marched steadily overhead.
