Those CSC charts are pretty and nicely visually tailored for remote places, on the basis of very skimpy data. Our forecasting systems are built around airports. The nearest places to Dinosaur Point, for instance, that get actual forecasts, are Gilroy and Los Baños, and weather in both those towns are often very different from what they are at Dino.
Same for all our hilltop spots, Coe, the Peak, Pinnacles, Montebello, Lake Sonoma, etc. The weather forecasts we see are not for hilltops.
Bill Arnett, the nineplanets.org guy, said a while back about the CSC, ""It seems to be VERY local. And I don't trust it anyway."
Far better to get out of the house and go see what it's like in the dark.
