Issue running nwm_timeseries_local.ipynb #2
Description
@cheryldmorse Today I tried to run the above notebook, and encountered an error when running cell 4:
cat = catalog['NWM_Best_CONUS_Short_Range']
ds_sr = cat.to_dask()
ds_sr
I think it may have something to do with the set up of the Intake catalog itself, since there's not much going on in that call. The call to .to_dask() is where the error originates.
