Mike,

Currently the NDFD grids are available on the NWS ftp servers, not NOAAPORT
(and thus not yet on the IDD). I don't know of the distribution schedule 
for adding to NOAAPORT.

Already available in GEMPAK 5.6.J (released back in March) was the added
NDFD grib2 decoder (ndfdg2), and this is reworked for improvements in
the upcoming GEMPAK 5.6.K release. Also, the GEMPAK grid routines
are improved to handle subsetting and sampling of the higher resolution
grids (such as the 5km NDFD) for improved display capabilities.
