Benign Mammatus

Mammatus cloud formations began to move into the skies Eastern Iowa on the evening of Thursday, August 12, 2021. Many times mammatus accompany severe weather, where they extend under the base of a cumulonimbus, but in this case they did not. Mammatus clouds form as moist sinking areas, but moisture has been hard to come by for months at this location. The above pic looks northwest over Bowman Woods Park in Cedar Rapids. at 6:00 pm CDT.
