Many Thanks ALL!....Couldn't believe how fast it developed. There was a beautiful thunderhead on the horizon, but by the time I decided to take a pic, it had turned sort of bland. Then it grew in fast motion filling the whole sky. I was about ready to leave when I snapped this pic. As I was pulling out the downpour started along with lightning bolts and thunder.
I'd welcome that cloud with joy knowing it would cool things down some. We'er in a heat wave here in my area. Only a high of 95, but that's still way to much for me.
