Greetings!

There are two "potential vorticity" functions in MetPy:  
potential_vorticity_barotropic and potential_vorticity_baroclinic. The 
barotropic version does not require a 3D field, but the baroclinic version 
definitely does because it requires estimating vertical derivatives.

What 2D GFS fields are you trying to use? Is the function you're trying to 
replace publicly available somewhere?
