Oct 2/13 - Check out the tapering linear weather front making its way into California, northern Nevada, and southern Idaho. The radar doesn't show this "cloud" formation as containing any moisture (ie. Nevada), and the tapering cloud simply does not show up on the radar. With supporting photographs from SkyWatchers in Cali, Nevada, etc. should we presume that these "clouds" appearing on satellite are simply sprayed chemical agents that haven't collected any moisture as of yet. The last photo shows the front moving inland 7 hours later, showing signs of moisture that have been picked up and accumulated in the aerosols.
