I live on the eastern edge of what Arizonans call "the valley." Its a beautiful day here with mostly blue sky and a few billowy clouds. We get quite a bit of air traffic here. Several times today I have noticed that there are absolutely no contrails coming from the jets. At every altitude from several thousand to 35,000 feet no contrails. Then it hit me like a kick in the nuts, this is a federal holiday. No federal government employees working to mix the chemicals that make the chemtrails! Whatever else could it be? I mean other than a rare day with just the right temperature and moisture content of the air. I'll be watching on other federal holidays to see if it is in fact a trend.
