I was driving this evening when suddenly conditions went from absolutely still to such wild wind that I could hardly keep the car on the road. The sun kept shining, no rain or storm threats -- just crazy, scary wind. Then it subsided, just as quickly as it came. When I got home, I turned to look back, and saw this.
Well, I guess that explains it. This Monster Cloud spit out a big chunk of wind, and I got caught in it!
