All these products are based on numerical simulations performed at National Centers for Environmental Prediction (NCEP) - NOAA and the Environmental Modeling Center (EMC) NOAA. A great thanks goes to these groups without whom this page (and others like it on the internet) would not be possible. Some model graphics are now available directly from NCEP.
