Unless that airport is one that is not authorized as an alternate. As I understand it, most that don't
have wx reporting are so designated.

I think it is approaches that are NA, not airports. For instance W50
has no IFR approaches, so it has no NA approaches and the AFD does not
indicate it the airport is NA. I would assume that any visual approach
that is not NA is suitable for an alternate.
