Her face was clouded with anxiety.

I think it's clouding up.

It's cloudy.

It's getting cloudy.

As it was cloudy, we could not enjoy the view.

Cloudy days, they stopped on their way and could not return home.

All of a sudden, it became cloudy.

The steam has fogged my glasses.

Scarcely had we started out before the sky became overcast and down came the rain again.

It was cloudy yesterday.

It's cloudy today.

It was cloudy all day long today.

It is cloudy now.

The sky is becoming cloudy.

The sky clouded over.

The sky clouded over.

The sky has become overcast.

The sky has gradually clouded over.

All of a sudden the sky became overcast.

It's getting cloudy. It may rain soon.
