These clouds, the very first ones usually precursors of disturbances, are overhead now with the airways crossing Arizona evident in the “condensation trails” (contrails) showing their positions. FORTUNATELY (the writer despises contrails), there are few overhead of Catalina-Tucson area because there are few airways overhead. Most of our contrails are to the north of us, likely representing cross country flights to Los Angeles. As some may know, contrails are considered a sky contaminant over such national treasures as the Grand Canyon. Also, with air travel predicted to double in the next ten years, more of them are likely to spoil more and more skies. (OK, this is a first shot at writing anything on a web page, so if anyone sees this, please forgive errors in constructing proper sentences.) Expect to upload cloud photos with some discussion of what is being looked at before too much longer.
