[python #VUC-241122]: Some of examples not work

Greetings!

Apologies for the delayed response. It looks like this notebook needs some 
updates due to changes in our THREDDS data server.

The cell causing you problems should really look like:

from metpy.units import units
import numpy as np

# get netCDF variables
pressure = point_data.variables["altitude"]
temp = point_data.variables["Temperature_isobaric"]
u_cmp = point_data.variables["u-component_of_wind_isobaric"]
v_cmp = point_data.variables["v-component_of_wind_isobaric"]
relh = point_data.variables["Relative_humidity_isobaric"]

# download data and assign the units based on the variables metadata
# Need to put units on the left to assure things work properly with masked 
arrays
p = units(pressure.units) * pressure[:].squeeze()
T = units(temp.units) * temp[:].squeeze()
u = units(u_cmp.units) * u_cmp[:].squeeze()
v = units(v_cmp.units) * v_cmp[:].squeeze()
relh = units('percent') * relh[:].squeeze()

Once I make that change, the cell runs without error. I've opened an issue to 
remind us to update that example:

Thanks for reporting!

Cheers!

Ryan
