Today in 2015, the Global Forecast System (GFS) is a cornerstone of numerical weather prediction in NOAA, giving 13 km horizontal resolution forecasts four times a day out to ten days. A quick history of the GFS will be reviewed, along with the current science and evaluation of the present state-of-the-art data assimilation and modeling system behind the GFS. The purpose, science, and preliminary outcome of the next implementation of the GFS will be described. Finally, there will be a look at the future path of global Earth system modeling at NCEP.
