As a Midwesterner, I really do enjoy thunderstorms without TOO much worry about severe enough weather to be deadly. Where I live, we just don't have many tornadoes, floods, etc.
A thunderstorm in a tent is, like others have mentioned, a great way to see another side of nature.
Now, the areas where flash floods occur, like where you are, are a different ballgame. Unless you're confident about your hiking route and site selection, I'd personally hold off, especially with a newbie.
My 3 cents. (Inflation sucks)
