Well, it's certainly going to depend on your area. Best idea would be to
consult your weather service. In Canada we have a web site where you can
get the history of certain weather details at your location going back a
few years.

Off hand, the highest I've seen my weather station is 104.5, the lowest
is about 96. Normal ranges are between 98 (raining) and 104 (very clear
sky, middle of winter).

Have you considered a "calibrate" button that is depressed at the
surface and zero adjusts to that pressure?
