DISCUSSIONS: Across portions of the Southwestern United States there is a very neat array of cloud cover as shown in the image below courtesy of the National Weather Service office in Grand Junction, Colorado! Note how there is a combination of smoke plumes emanating from wildfires emanating from Central and Northern Arizona, anvils associated with severe thunderstorm activity based in Central New Mexico, and jet contrails located in Eastern Wyoming! As a point of reference, jet contrails are induced as a result of the condensation of water on the particles which are emitted in association with jet fuel exhaust. It is quite impressive to see so many unique cloud structures in such close proximity to one another!
