A big cloud had rolled across the face of the sun.

The sun was down now, and clouds were rolling in.

Then the clouds rolled away this morning and now look at it.

Finally, the clouds rolled away and the moon came out.

The fat man was fighting the cloud rolling into his mind.

A dark brown cloud rolled in to fill the sky.

There were low, dark clouds rolling over the city as they approached.

Clouds rolled slowly across the sun, and the air grew cool.

Or it would have been, had dense clouds not rolled in.

Clouds of purple and yellow rolled in from the north.
