The warning may have been fixed in the development version of dask by https://github.com/dask/dask/pull/5103

The computing on empty arrays thing is due to the new meta tracking in dask 2.0, used for tracking the underlying type of arrays in a dask array. Dask supports setting meta explicitly inside blockwise. We might consider exposing this from xarray as well.
