[python #DCS-251943]: MetPy time series plots

Greetings!

We appreciate the feedback. We really want that code map to be able to handle 
everything and so I consider it a bug that it fails for that--but I do think 
it's valuable that it fails since that led you to let us know it's broken. :)

Fortunately, you can already get the behavior you're looking for. `wx_code_map` 
is a regular python dictionary, so you can us it's built-in `get` method:

  https://docs.python.org/3/library/stdtypes.html#dict.get

like this:

    wxcode_num = wx_code_map.get(wxcodes.split()[0], 0)

Hope this helps,

Ryan
