Driving west on I-10 Sunday, I saw again why California has a desert. The moisture from the coast rarely makes it very far inland. This is at the San Gorgonio pass, about 100 miles E of Los Angeles. See the windmills? They’re there because there is usually an east wind (i.e., westbound). When there’s weather in the Inland Empire and it wants to go east, it can only get this far.
