Hi Rob,

You have to use the projection Lambert Conformal for NDFD files to convert the 
projection coordinates to the lat/lon coordinates. 

After you get the grid, get the GridCoordSystem: getCoordinateSystem()
http://www.unidata.ucar.edu/software/netcdf-java/v4.0/javadocAll/ucar/nc2/dt/GridDatatype.html

Now get the projection: getProjection() 
http://www.unidata.ucar.edu/software/netcdf-java/v4.0/javadocAll/ucar/nc2/dt/GridCoordSystem.html

Now you have the Lambert Conformal project
http://www.unidata.ucar.edu/software/netcdf-java/v4.0/javadocAll/ucar/unidata/geoloc/projection/LambertConformal.html

Use projToLatLon()  to convert the projection coordinates to lat/lon 
coordinates. In a previous email, there was code to get the GeoX and GeoY 
projection data. 

I'll ask the another developer if there is a better way to convert projection 
coordinates.
