Night lay over the wasteland, and clouds closed in above.

The clouds had closed in as they neared the top of the pass.

The clouds were closing in over the harbor; it was going to snow again tonight.

The cloud closed and, as the city rotated into position, made contact directly above.

The black clouds closed like a tomb, for the sun was dead.

The next the clouds closed in and they had vanished from view.

The clouds had closed in again and there was no moonlight.

Sometimes the clouds closed in, and they could see nothing.

I just saw it for a second before the clouds closed up.

Outside, the clouds were closing in and the air was becoming increasingly rough.
