Defying the sign below, an increasingly dense cumulonimbus anvil spreads across miles of sandy Arizona desert, originating off the Chiricahua Mountains at unseen right rear. Do you think the atmosphere cares about this sign (other than to pop it with lightning sometime)? Befitting the fickle nature of orographically fired monsoonal multicells, areas of the mountains and immediately adjoining deserts would get a quick inch or more of rain, while nearby Willcox only experienced sprinkles as the anvil floated overhead and shriveled. Some lunch in town and a visit to the Rex Allen museum were in order until more storms formed to the west, ultimately producing a funnel cloud over Tucson.
