Outside dark ominous clouds begin to gather above the house.

Dark and ominous clouds rose up, the wind bit harder, colder.

I half expected to see ominous dark clouds boiling over the building.

At one point we drive into an ominous cloud.

I looked to the west where there were ominous dark clouds.

But these same forces have cast an ominous cloud here.

Slowly, the ominous clouds gave way to the blue sky, and the winds died down as if on cue.

At the time of the crashed, witnesses said the sky had turned dark with ominous clouds.

But this situation hangs above him like an ominous cloud.
