Distant Updraft

 

In keeping with the norms during the 2025 severe-weather season, storms avoided the Cedar Rapids metro  area on Sunday evening, June 29, but about 40 miles to its northeast this lone mushroom cloud updraft formed, sporting a pileus feature on top. This image was captured at 7:47 pm CDT. Pileus are typically formed by drier air with a higher lifting condensation level which often prevents vertical growth and leads to its distinctive smooth cap shape. Nikon Z6ii camera.
