This beast of a storm had some incredibly cool clouds on its underside. The hail roar as it passed by was absolutely amazing and went on for 20 minutes straight.
Hail roar is oftentimes mistaken for thunder but is in fact the rumbling sound of hailstones cycling up and down within the storms structure and smashing into each other. It usually sounds like a low rumble, generally constant in tone and volume.
Seeing a storm like this is cool; hearing it adds to the excitement and drama.
