This is what a typical afternoon looks like near my home in Florida. These cells contain a lot of energy which lifts the moisture vertically resembling a mushroom cloud. Non-stop lightning is generated such that it will take your breath away if you've never seen it before. The first time I saw it I thought the aliens had invaded as I looked around at the locals who took no notice. As soon as it gets dark the skies light up in every direction as spectacular as fireworks. I just got back from walking my dogs around the block and directly above are stars, yet all around me were these clouds flashing in all directions. Now, I'm a local and I hardly notice.
