Why do my brakes squeak more in the morning than the afternoon?

I have noticed a pattern with my car that I cannot figure out. Every morning when I first leave for work, the brakes make this embarrassing high pitched squeak at the first few stops. But once I have been driving for about ten minutes, the noise completely goes away. I asked my coworker about it and he said it might be moisture or rust forming overnight, but I wanted a more detailed explanation. I was browsing online and found a helpful breakdown that explained the difference between morning dew affecting the rotors versus actual wear indicators. If you want to understand the science behind it you can read more here  because it actually goes into the whole temperature and material expansion thing that I never considered. Has anyone else experienced this morning only brake noise and found a permanent fix?
