And then I noticed a dark threatening cloud hovering above.

I stole a look at the door, trying to judge how soon the threatening clouds would cut loose their burden of snow.

It was warm and clear, as if the threatening clouds of the night before had left to make them the present of a splendid day.

The impossible standard of who I "should" be towers over me like a threatening cloud.

He glanced up at the threatening clouds and then took a hurried breath.

Although the threatening clouds had brought no wind, dust was swirling through the streets below us.

Above their sharp crests what little light was left in the sky came from between heavy threatening clouds.

A few threatening clouds had come in from the sea, and the air was cool and damp.

Now the threatening cloud from the nuclear blast vanished.

The air inside was at once cold and close, and the heavy dimness came down upon his spirit like a threatening cloud.
