Sounds fairly simple to me. 2" X 12"s on 16" centers are suitable for a heavy snow load with a 20' span (40 PSF). Of course, with a good pitch, like a vertical foot for every 2 1/2 feet horizontal run, which would mean the center pole being 8 feet higher than then the eaves, will require a distance of approx. 22' from sidewall to center, and if you want a 2' overhang, then you need 24' rafters. You could also, if desired, eliminate the center support pole, but then would have to come up with some sort of collar ties or cables to keep the walls from pushing out.
