I'm not familiar with the GC climate in mid November. I was once there in mid April though. We drove out of Vegas in sunny 25C conditions only to hit snow and icy road conditions some 3/4 of the way to GC. We didn't have any winter clothes either! Check the weather forecast before you leave. Take care and enjoy.
I had a similar experience. Snow at Williams and when we got to the Canyon, the cloudbase was below the ridge so we couldn't see anything. There was a bitter wind so we just got back in the car and drove to Pheonix where we could sunbath by the hotel pool.
Unfortunately for us, the Grand Canyon is just a big hole in the ground.
