Low-lying black clouds were shifting in thick, grotesque shapes across a huge fat full moon.

The clouds had shifted slightly also, though not enough to cause concern.

Sometime toward noon the dark gray clouds had shifted to the horizon and the sun had come out.

The clouds, black and pregnant in the underbelly, shifted uneasily, promising violence.

The cloud shifted shape as they approached it, and the colors danced throughout the spectrum.

Roiling black clouds moved and shifted, but never revealed anything except more blackness.

The clouds in his mind shifted and swirled.

The cloud shifted colors, became orange, almost like a swirling ball of flames.

Before long, the clouds would shift and destroy his illusion.

Blint smirked, but the dark cloud over him didn't shift.
