I love watching cumulus clouds billow and tower against a deep blue sky. Lately we have seen some of that with the scattered rain and thunderstorms that are a part of spring. In the early evening Sunday, the sky was changing from mostly cloudy or overcast to partly cloudy, allowing views of the cloudy blooms. I shot a good number of photos and it was difficult to choose what to show here. My shoot ended as the puffy towers passed overhead and no longer showed their profiles. A high-flying aircraft left a thin contrail, seemingly ejected from the clouds, high above it all.
