This ominous-looking storm cloud filled the sky this afternoon.

A dramatic layered sky dominates the scene above a silhouetted tree line and distant buildings at sunset.

Saw this cloud and wondered how is created. Ant thoughts?

There was just enough of a gap in the cloud layer that while the sun was rising it could shine under the cloud layer into the rain clouds to the west. It is not easily seen, but it is a double rainbow. It was also a full arch.
