Altocumulus Family: Altocumulus becomes altostratus.

Altocumulus floccus (like tufts of wool) cover the sky over Cedar Falls, Iowa during the afternoon of November 6, 2017. The cloud ceiling was measured at 11,000 ft. at the Waterloo, Iowa Airport. A combination of a moist layer and turbulence likely created the altocumulus which spread in to an altostratus layer.

There were several variations of altocumulus floccus. Notice the more diffuse version below. Organized bands of waves are seen rippling through the layer creating alternating cloud bands with clear strips in between.
