How do you do your forecasts?

The weather often chooses it's own path of action, and we're in a constant state of trying to keep up with it and create forecasts that are accurate and reliable. To do it, we use over 6 different sources of data, apply our own proprietory local area algorithms, a human touch, and the results are the graphs you see. We built the systems years ago, but the code was lost in an unfortunate office accident late one evening during a christmas party windup involving an employee, a gold fish bowl and a set of golf clubs. The code was lost and the employee now has a limp. :-)
