I had read CTP's afternoon disco where they all but completely dismissed a severe weather threat yesterday, so as an acting weather weenie I was trying to prepare fans last night for lightning and heavy rain. I went beyond my duties and started asking people to leave the seating bowl due to all the cloud to ground strikes going on, people seemed oblivious to it. Anyway, the sky got really ominous to the southwest...probably one of the scariest skies I've seen. I wasn't prepared for that based on the information I was getting from weather outlets.
My wife was driving home and she stopped at various spots and took like 50 pictures. I posted the one because I've never seen anything like it. She did say that what I posted lasted seconds before it dissipated.
