A Line of Thunderstorms

Having just finished Bernoulli in my classes, my students were inappropriately excited about the possibility of tornadoes in our area tonight. (I'm going to crack the windows even if my parents think I'm nuts, because we just learned about it!) Of course, they are young and immortal, so they view storms with a different perspective than I, a homeowner and father of two. I will be spending this evening preparing a lesson on lightning (on my laptop) and hoping that the storms don't bring any damage to our area.
