Ambivalent clouds.
Are you going to rain or not? The dark bottom part is raggedy and threatening, but the top isn’t so sure at all.
The top part wants to rise, go up to 10,000 or 20,000 feet, get icy and thin.
These guys over here already developed an altitude and they’re just blocking a touch of sun. (Eventually the lower, thicker clouds blew off toward Las Vegas and rained there.)
