I almost never do this sort of thing, but I stopped the car to catch these clouds over the Sacramento Valley. I'm heading south just above Knights Landing, i.e., maybe 20 miles northwest of Sacramento. I've been doing this run off and on for something close to 35 years. We often get storms (often rather nasty, with sleet) out of the south, but I don't think I've ever seen a front here so clearly defined.
