*****************************
Possible values for <wx_code>
*****************************

This is a list of possible values found in the <wx_code> tag in the API. This
field provides an alternative to using the <wx> value. **These two values will not
always provide the same information.**

In this case, some added detail may be possible. This is especially true
in the <sfc_ob> section since the
original source data might have more detail.
In many cases, they will share the same information:

.. code-block:: html

	<wx>Clear</wx>
	<wx_code>100</wx_code> (100 in this table represents clear.)

In other cases, additional detail may be provided:

.. code-block:: html

	<wx>Thunderstorms</wx>
	<wx_code>95</wx_code> (thunderstorm)
	    or
	<wx_code>97</wx_code> (heavy thunderstorm)
