Brian,

The current status:  a grib2 (Dump program) has been written in Java. I
haven't been able to work on it for 6 months, the  plan is to add
the netcdf API on top of the dump program. Hopefully I will be able to
restart work on it soon. The NDFD grib2 files will be easy to create but
some of the stitched grid models require more work. For sure a grib2
decoder will be available when the NWS starts regular distribution in
grib2.

Robb...
