If the ATC sector that will cover the BNA Broadcast Area doesn't have this met info displayed and the ability to provide it and the other operational information, then my interpretation is that an AFIS would not be compliant.
FWIW from the CASA VFRG:
They do have met info and an ATIS which is kept up to date. All the operators there also are approved met observers. It's set up to run the same Karratha class D just without the control aspect.
