OF THE
TIMES
"An updraft pushes flattish cumulus clouds up and a horizontal vortex develops from differential updraft speeds.So, if you ever see a horseshoe cloud, make sure to snap a photo, because you're one of the lucky ones.
As the vortex climbs, it gets caught in the faster horizontal winds aloft, and the middle part of the vortex catches the faster speeds with the ends being slower.
The result is that the center of the vortex pulls out ahead. Various time lapses can be found online."
