Sharp cutout in heavy cloud layer, stayed static and lines very defined before clouds immediately recondensed.

Football pitch sized (approximate) sized cutout opened in the dense clouds at night, moon visible through this hole. The edges of the clouds were sharp and the shape was distinctly symmetrical down the length of the would-be object. This was directly over Lunken Field in Cincinnati, Ohio. Four to five minutes elapsed, and the cloud volume swirled back into place rapidly. There was apparent cloud movement in the lower atmosphere that night, and this punch-out stayed perfectly still during the duration it was there. I have not seen any online live-feed or Artemis cameras from that night that would be facing directly upward or have that portion of the sky in their field of view. Local AM radio was not being received by my vehicle at the time this occurred, then was clear when switched back on after returning to car.
