Hi, and thanks for the follow-up.

Inspecting your wrfout file by hand using other tools like xwrf or Pyproj for 
converting latitude and longitude to x and y, I get comparable pressure values 
to your "correct" Skew T's. MetPy is not modifying your data, and 
`resample_nn_1d` will only return valid pressures from your original data.

Double check your usage of wrf-python's `ll_to_xy` and how you're subsetting 
your arrays. Note that by default, the xarray.DataArray I got back when testing 
with wrf-python was ordered (z, y, x), not (z, x, y). I think you may have 
swapped your x and y and so are looking at incorrect locations altogether. Take 
a look and let me know if this helps. 

This shouldn't be a MetPy issue, but I hope this still helps. Thanks!


All the best,

Drew
