Marie Botchie (Member 65,477) spotted mamma features hanging beneath the canopy of cloud that stretched out over Paw Paw, Michigan, US. The layer was likely the upper part of a distant Cumulonimbus storm cloud. The rounded pouchlike features can develop when cold air within this spread-out upper part of the storm sinks in pockets, pulling the cloud down in distinctive bulges. When Cumulonimbus clouds move through a region, mamma features like this tend to develop at the storm’s rear. Marie noted it was a drizzly day, suggesting she was catching just a little peripheral precipitation while the storm shed heavy showers off on the horizon to the right.
