Is xarray responsible for putting the arrays into a tuple upon function completion, and if so where should I go to look into that?

No, I don't think xarray is responsible for this. Depending on the options you pass to apply_ufunc ( e.g., vectorize=True) we may substitute a function for the provided func, but that's not the case by default.

I think this is the line in your function where you return a list: https://github.com/monocongo/climate_indices/blob/cd1982752e288cf02d50ca0680744842bde16293/climate_indices/palmer.py#L1937
