Eli5: Why is California so dry even through is it near the ocean?

Why does California not get the typical afternoon storms that the eastern costal cities/towns get? I was under the impression that those storms were caused by the heat and evaporation of water from the ocean. California has both heat and ocean yet they don’t get the same storms.

The east coast has the gulf stream which brings warm moist air from the Gulf of Mexico up the coast. The west coast has the opposite effect. They have an arctic stream the draws cool dry air from the arctic down the coast. If you've ever been in the Pacific ocean, you'll notice right away that it is cold even in the heat of summer.
