Oklahoma weather is crazy, 75 and sunny one day, snowing the next, and a tornado the week after.
But OU's campus isn't too spread out, so the weather has never presented a problem for me. If the weather is wretched, I'll just cut through other buildings to get to the one I'm going to. Also, you hardly have to worry about walking through the snow. Pretty much if snow is sticking, class will be canceled.
