Sacramento Delta V: Rio Vista Wind Farms

When I first moved back here, I started noticing this really strange tendency on the weather radar maps around the Bay Area. No matter what, there was always what looked like blobs of thunderstorms happening in the same spot, every day. Well, here it is. The windmill farms just outside of Rio Vista. My understanding is prevailing winds from the west come whipping through the Carquinez Straits, and up the Sacramento-San Joaquin River Delta. BTW, much of this land is being used, also, for ranching, mostly sheep, some cattle.
