Pileus Cap On April 27 Storm Cell

This storm cell had passed east over my location at Brentwood Drive NE in Cedar Rapids, Iowa on the evening of Monday, April 27, 2020. As it did so, it acquired a pileus cap (right) at 6:25 pm CDT. Pileus are short-lived formations created by strong updrafts at lower altitudes acting on moist air above, causing the air to cool to its dew point. Moist pileus are associated with severe weather, but this particular occurrence was not. Weather conditions at the time were: 74 degree F temperatures, 52 degree dew point and 47% humidity.
