This is just the action of hot updrafts against a cold rain-cell.
When it breaks the boundary of gravity against thermal, it precipitates in a hard-line front.
It rains or it hails.
I stood under one such as the hail as big as baseballs smashed cars so hard the occupants could not operate their I-Phones.
