IT’S THE TENTH ANNIVERSARY OF THE JARRELL, TEXAS TORNADO: Warnings are better, but tornadoes like this are hard to survive. Makes me glad I got the weather radio that I mentioned a while back, though happily tornadoes aren’t a big issue in Knoxville. We get ’em, but they tend to be comparatively weak and short-lived.

And if tornado-related issues interest you, check out the NOAA Skywarn page.
