Trying to download directly from NOAA.
Anyone know what these Data files are?
Which one do I pick?

I am wanting to write a little fetch script so i always have the latest 3H GRIB.

The documentation isn't very helpful either.

EDIT: I figured it out. Each of data files is a prediction model xxx hours from the simulation time.

NOAA servers being REAL slow today as well...
