Normal humidity in St. Louis at this time of year is about 40-50 percent. Thirty percent would be considered very low humidity. (Information provided by in-house meteorologist.) On Sunday, our humidity was 16 percent at its lowest; 17 percent when I took this screenshot.

So what do you get in this area when the humidity gets that low? A fire weather warning! If it’s not one thing, it’s another. At least it wasn’t a spring tornado.
