Mostly clouds

A cumulus congestus forming in the distance while the night is falling.

Oh, the sky is full of cotton balls !

Heavy stratocumulus clouds covering the sky like an armada of threatening alien spaceships advancing low over the city.

Ominous cumulus congestus rising up in the distance.

Stratocumulus clouds blocking most of the sun light. But we can see the sky through a hole.

A monstruous cumulus congestus rising.

Altocumulus radiatus

Altocumulus radiatus in the distance.

Virga clouds in the sunset.

A lonely cumulus in a beautifull summer sky

A cumulus congestus rising above the city like a mountain.

An altocumulus and its flock of small cumulus clouds in the sunset. And a funny looking condensation trail.

The burgeoning side of a cumulonimbus an evening before the storm broke out.

The pale light of the setting sun piercing through the bottom of a cumulonimbus. A thunderstorm started a moment later in far distance.

Alto cumulus undulatus
