I'm guessing that you didn't really mean that, Steve. A forecast model can certainly predict weather better than somebody who is sitting out under it. For a recent data point, yesterday's wind and blowing dust event was predicted perfectly in the extended forecast last Saturday, right down to nailing the high temperature within a couple degrees. The unsolicited forecast from the NWS for western Arizona this weekend is very light southwest breezes, and very comfortable nighttime temperatures for observing. Since nobody but us cares about cirrus clouds, they go with "partly cloudy" nights. Take a look at the Clear Sky Chart on Friday, and the Canadian Meteorological Center's model (which does care about cirrus clouds) will give us an idea if it's going to be transparent.
