This evening, as I left work, I looked west towards the Sierra Mountains, seeing the clouds of an approaching storm. The clouds looked darker than normal, almost having an evil feel to them. I saw a flash of light out of the corner of my eye, but thought it was just the headlights of a car as it makes a turn. It wasn't until I was driving in my car that I finally saw it - there was actually lightning in the sky. I've never seen lightning this late in the year. It is very weird to be wearing a heavy jacket to keep warm and have weather you would associate with the summer happening outside.
I arrived home, got my mail, and as I got back into my garage to get my things out of my car, the rain started to fall, as if nature waited for me to take cover.
