As I walked to the bus stop 20 minutes ago, I noticed that the western horizon looked dark. No, saying that it looked dark doesn't really do it justice - it looked like impending doom. I watched it roll toward me well past the time my bus was supposed to arrive. A friendly passerby eventually told the assembled bus-stoppees that service was on hold because of a tornado warning. In the 5 minute walk back to my office, the temperature dropped by 10-15 degrees and it got subtantially darker. Still, in the end, I'd take a mouth-of-hell spring storm over a blizzard any day.
