It is nowhere near a CF compliant file.

I would think the first warning would indicate that this doesn't have the CF
Conventions attribute.

In any case, this is not what I would call a "self describing" format.  There
is no documented standard (except in some C code according to the web page).

One could write a convention handler for this, but I'm not sure if it's worth
the effort.

A better effort would be to get the NWS to write out CF compliant netCDF files.
