It's easy to predict the weather in Los Angeles: it's pretty much the same every day. I never realized how bad meteorologists were at predicting the weather until I moved here to St. Louis. They're commonly off by 10 degrees or more, and they can't even say if it's going to rain or not. For instance, yesterday was supposed to have a high of 78, but by late morning the temp was already 86 and the weathermen didn't even bother to update their forecasts! Today is forecast to be "8 degrees warmer than yesterday" but it's definitely not going to be 94... which means that it will probably be 86 again, and that the weathermen didn't even notice how far off their predictions were yesterday!
