CFInvoke CDYNE weather

There are 3 methods to use with cdyne:  (1) getcityweatherbyzip  (2) getcityforecastbyzip (3) getWeatherInformation

More information can be found on their site at http://ws.cdyne.com/WeatherWS/Weather.asmx

The first two are pretty straightforward and return the values needed:

<cfinvoke webservice="http://ws.cdyne.com/WeatherWS/Weather.asmx?wsdl" method="getcityweatherbyzip" returnvariable="aWeatherReturn">
<cfinvokeargument name="ZIP" value="27502"/>
</cfinvoke>

<cfoutput>
#aweatherreturn.weatherid#<Br />
#aWeatherReturn.temperature#<br />
#aweatherreturn.description#<Br />
#aweatherreturn.weatherstationcity#<br />

</cfoutput>

<cfdump var="#aweatherreturn#">

I am stumped on method 3, getWeatherInformation.  Does anyone know how to get the returned values for weatherid, description, and pictureURL from this method?  I don't get this.  How does it know what area/zip for this method?

<cfinvoke webservice="http://ws.cdyne.com/WeatherWS/Weather.asmx?wsdl" method="getweatherinformation" returnvariable="bWeatherReturn">
</cfinvoke>

<cfdump var="#bweatherReturn#">

<cfoutput>#bweatherreturn.weatherdescription#<Br />
</cfoutput>

Here is an example of my results for both methods:

Thank YOU!  Once this is resolved, I hope to have CDYNE post this example on their website to help others.  They have an example of the other methods, but not this one.
