Could of fooled me

If you could guess...? What does this look like? I am driving home from work yesterday and I call Mark to see if the storms have calmed down. As I look to the right I see this! No answer, so I call my mom...I take a pic on my iphone, email it to her and ask her if a TORNADO was in the area? She checks and says NO, so it seems to be following me in my car.. ok so its not a tornado, but to my Floridian Eye, it sure looked like one. CREEPY!
