Greetings!

Apologies again for the vastly delayed reply. See my responses in-line below:

Actually, that looks like a pretty big oversight on our part. Right now the 
easiest way would probably be to convert your data. You can also pass a 
function to `format`, so you could define a function:

    fmt_fahren(v):
        return str(v * 1.8 + 32)

I don't consider either particularly satisfying, but that's how I'd approach it 
today (until we put something better in MetPy).

We want to add a way to zoom in on top of specifying with 'ca' with 'ca+', but 
that has not yet been implemented, see:

https://github.com/Unidata/MetPy/issues/1288

For now you can specify a tuple of (lon0, lon1, lat0, lat1)

Sure:

    pc.save(bbox_inches='tight')

This syntax comes from matplotlib:

https://matplotlib.org/3.1.1/api/_as_gen/matplotlib.pyplot.savefig.html

There was not a formal plan in place but if that would be helpful, I can look 
at moving it over.
