A suddenly flaky internet connection was the first sign. Usually this means a thunderstorm is on the way, or else someone has cut my ISP’s fiber cable again. I looked at a weather map, and saw that a very strong storm was brewing across southern Missouri and southern Illinois. But I couldn’t have guessed just how bad of a storm it would be.
Moments later a weather alert email appeared, saying there was a tornado watch in effect. I heard rain and thunder, and a little later my lights flickered and went out. The wind was picking up, so I went to a window to see what was happening.
