Can't really make it out but that is hail falling.
This was in the very beginning so doesn't look like much. It hailed for quite some time. A few minutes. Looked like ping pong balls bouncing in the yard.
A closer view of some of the hail that was falling.
It really is some cool stuff to see. It looked like snow in the yard at one point.
Kids were watching the hail in the pool and watching it bounce off the deck.
