Cumulus clouds with a layer of dark storm clouds.

Cumulus clouds, darkening, impending storm.

A dramatic sky with cumulonimbus clouds. The lower portion of the clouds are dark and ominous, while a large, puffy, white cumulus cloud sits atop them, illuminated by the sun. The contrast between the bright, light-filled upper cloud and the dark, heavy clouds below suggests an impending weather change, possibly a thunderstorm. No people or other objects are visible in the image.
