Here is a link to a site run by Dr. Jeff Masters. It shows the official forecast cones and also has a couple of versions of the computer forecasting models. He often posts new computer models that give a close indication of the official forecast will be a couple of hours before they appear on the government sites. Some of those models can be all over the place, but the composite and GFS models seem to track closely to reality.
