Photo taken just as I was pulling up to work. I hurried into the building before it hit. Poor quality image taken with cell phone.
I love nature photos in general but when I can catch an image of something decaying or potentially violent I find it worth saving. Storm clouds are so mysterious to me. Something about the potential behind the clouds brings a level of uncertainty which for me defines much of my life.
I was a little disappointed with this storm front when it blew over with just a spot of rain and a little lightning.
