What is the normal fallback for local weather service failure? Divert to an airport with working service? Proceed, using the "nearest working" information?
How much does air pressure vary over a region, and how quickly does it change?
I think it would be "fly vfr" but the main issue there is the wind direction, not the altimeter setting. In daytime you can read the wind sock while airborne but not possible at night.
