Cumulus cloud formations, summer day, blue sky


Small clouds of the genus Cumulus are often associated with fair weather. However, they are the product of convective airmass instability and can grow into more storm-like buildups including cumulonimbus. Continued upward growth suggests showers later in the day. These clouds usually form below 6,500 feet but can be based as high as 10,000 feet under conditions of very low relative humidity.
