These are pics of a couple storms from 2005. The first pic is of a tornado front that was passing directly overhead the neighborhood we lived at the time.
The last couple show a severe thunder storm that created a thick, vivid line across the length of the sky over town. It was the weirdest cloud formation I've ever seen, and the pictures don't do it justice. As the storm approached, the clouds split right at the line so that it looked like there were clouds on the bottom, clouds on top, and rain inbetween.
