Describe a scary moment in a storm.

I live in Oklahoma, so we see our fair share of storms. Storm sirens are so common that I don't take cover every time they go off. Instead, it's normal for me to watch the radar when a storm system is moving through to see where the tornados are and how close they are to me. 

Once, the radar showed a tornado southwest of our house - moving towards us. When it was within a couple miles of us, my wife took the dogs and blankets and went to our safe place - an internal bathroom. I stood back from the windows and watched the tv. From my position, I could see out the back windows which faced west - southwest. The weather showed that the tornado was right on top of us. I watched out the window as a fragment of a four by four, about a foot and a half long, flipped up from the ground and tumbled across the lawn. 

It was that moment that I decided I had watched enough and stepped into the bathroom to join my wife and the dogs. The storm blew over us. The tornado wasn't on the ground as it passed by, but it was definitely and intense several minutes as we waited. 

I have seen my fair share of storms and had a number of close calls with tornados. This definitely falls in one of my top 5.
