As I stepped out of the house this morning, I looked up and saw this cloud pattern covering the entire sky. It brought a smile to my face. What a way to start the day!

Another fine example of God showing off.

Checking the classification over at the University of Illinois taxonomy, I would say that these clouds are altocumulus.

Altocumulus may appear as parallel bands (top photograph) or rounded masses (bottom photograph). Typically a portion of an altocumulus cloud is shaded, a characteristic which makes them distinguishable from the high-level cirrocumulus. Altocumulus clouds usually form by convection in an unstable layer aloft, which may result from the gradual lifting of air in advance of a cold front. The presence of altocumulus clouds on a warm and humid summer morning is commonly followed by thunderstorms later in the day.
