I grew up in Michigan where thunder & lightening is common. I moved to So. Cal in 1977 for college. We rarely have thunder & lightening here. When we do I am overjoyed, I love lightening. I can only remember a few thunderstorms here over the years. A few months ago we had a very short lightening storm, short as in under 20 minutes. I was just wondering why it is such a rare phenomenon here.
