Here is what I did:

Make new environment
```
conda create -n test_xarray xarray netcdf4 dask
```

Check version
```
(test_xarray) kthyng@adams ~ % conda list xarray
# packages in environment at /Users/kthyng/miniconda3/envs/test_xarray:
#
# Name                    Version                   Build  Channel
xarray                    2023.3.0           pyhd8ed1ab_0    conda-forge
```

In python:
```
import xarray as xr
urls = [""https://opendap.co-ops.nos.noaa.gov/thredds/dodsC/NOAA/WCOFS/MODELS/2023/03/31/nos.wcofs.2ds.n001.20230331.t03z.nc"",
        ""https://opendap.co-ops.nos.noaa.gov/thredds/dodsC/NOAA/WCOFS/MODELS/2023/03/31/nos.wcofs.2ds.n002.20230331.t03z.nc""]
xr.open_mfdataset(urls)
``` 
returns the following the first time `xr.open_mfdataset(urls)` is run but the second time it runs fine.
```
OSError: [Errno -70] NetCDF: DAP server error: 'https://opendap.co-ops.nos.noaa.gov/thredds/dodsC/NOAA/WCOFS/MODELS/2023/03/31/nos.wcofs.2ds.n002.20230331.t03z.nc'
```

Next I used the PR version of xarray and reran the code above and then it was able to read in ok on the first try.


Note: after a week or so those files won't work and will have to be updated with something more current but the pattern to use is clear from the file names.","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,1385031286
