Contrasting with the hard surfaces of metal, concrete and glass, this beautiful fluffy cloud against cerulean sky stopped me in my tracks today.

From where my bike was parked, a street over, I could see the flat base of the cloud – as you might draw a fluffy cloud – but you would have to be expert to capture its shapes and shadows.

Cumulus – known as fair-weather clouds because they usually indicate fair, dry conditions. If there is precipitation, it is light. The clouds have a flattish base with rounded stacks or puffs on top. When the puffs look like cauliflower heads they’re called cumulus congestus or towering cumulus. They can get very high.
