Following severe weather of July 20, 2019, our skycam caught several rising moisture plumes over the Mississippi River Valley in La Crosse.
First is a clip sped up by 8x followed by the full video at regular speed. Jump to 3:25 to see the most intense plume in real time.
While some do have a tornado-like appearance, they are NOT tornadoes and caused no damage. They're simply plumes of rising, moist air and are somewhat common to see in the terrain of the coulee region.
