Occurred on August 24, 2021 / Milwaukee, Wisconsin, USA
Info from Licensor: "I was with my family on the south side of Milwaukee on a perfectly clear afternoon, when suddenly, the sky darkened. These dramatic arcus clouds moved so fast that I thought the only way to properly capture them was with a time-lapse video. Within moments, the sky darkened, the wind whipped the sand around the shore, and we quickly took shelter in our vehicle."
