8 Sep 2015, all morning, clouds gathering over the mountains ringing Colorado River Valley, we went for groceries, I told my wife, finally, today's the day! Just took this pic off our patio, sun shining brightly, looking west:

Rain is pouring down perhaps 30 miles distant, over in California, maybe several miles in width, this is typical of precip. here, unlike temperate areas where huge areas are "socked-in" with cloud cover. My first sighting of this about 40 years ago, travelling on vacation, mountains perhaps 50 miles distant, one large cloud hanging over them, driving across seemingly endless flat desert toward that spectacle, I was dumbfounded! Bolts of lightning in that gray sheet! Never in my 30-born years had I seen something so unusual, regarding weather conditions.
I present it for those here who may never have ventured to the Desert before, or simply missed this type of rare (maybe 10-15 times a year) atmospheric scene. imp
