Hi Rob, I just downloaded a few of the NDFD .bin files from the NDFD ftp site and it looks like the .bin files are in GRIB format which the netCDF-Java library can read. I'm wondering if it is failing to recognize them as GRIB files because of the header information located before each GRIB record. I'll pass this over to our GRIB person to look at in more detail.
