What is going on with this rain?
We should not be too surprised with all the crazy weather that has happened over the world in the last few years, but rain in the San Jose California area in August is unheard of, and it has happened a couple of times in the last few weeks.

A lot of this moisture is coming from low pressure systems that are bringing moist air up from as far south as Mexico as part of the monsoonal flow. If you spend any time in the south west you know about those rain events, but for it to reach as far north as Northern California takes a very strong persistent flow.
