Place your weather file next to your osm, and run this OSW:

{
  "seed_file": "Model (IECC 2015 & ASHRAE 90-1-2013 - RTU-FPB).osm",
  "weather_file": "USA_TX_Corpus.Christi.NAS.722515_TMY3.epw",
  "steps": [
  ]
}

This will overwrite the weather file actually used by the model, so beware.

Test 1: provide a file that is in the same folder:

I created an empty.osm model, didn't not set a weather file. (I opened a terminal, loaded ruby bindings, and just did model = OpenStudio::Model::Model.new then model.save('empty.osm'). I put a weather file next to it in the same folder, USA_IL_Chicago-OHare.Intl.AP.725300_TMY3.epw. Created a test.osw:

{
  "seed_file": "empty.osm",
  "weather_file": "USA_IL_Chicago-OHare.Intl.AP.725300_TMY3.epw",
}

Here's the content of my folder:

$ ls
USA_IL_Chicago-OHare.Intl.AP.725300_TMY3.epw
empty.osm
test.osw

Then $ openstudio run -w test.osw

Worked perfectly.

As you can see, stepsisn't required (it works with it though).

Test 2: provide a file_paths argument

Only changed the OSW:

{
  "file_paths": ["/Applications/EnergyPlus-8-7-0/WeatherData/"],
  "seed_file": "empty.osm",
  "weather_file": "USA_VA_Sterling-Washington.Dulles.Intl.AP.724030_TMY3.epw",
}

The Sterling weather file is NOT in the current directory, but it is in the directory I pointed for "file_paths".

Worked perfectly too.

Note that you can also have relative paths (compared to root, if root isn't set, that's the directory containing the osw. See the JSON Schema

Test 3: set the weather file in the OSM itself.

I opened empty.osm and set the weather file to another EPW (Tampa).

[4] TestOSW(main)> puts model.weatherFile.get

  847DE5F2;                               !- Checksum

The weather file, as expected, got copied to ./empty/files/USA_FL_Tampa.Intl.AP.722110_TMY3.epw.

Changed OSW to:

{
  "seed_file": "empty.osm",
  "steps": []
}

=> Did not work.:

$ openstudio run -w test.osw

I think it should work, so I'd consider that a bug.
