|•||State, City, WeatherStationCity - gives you some basic information about the ZIP code requested|
|•||ForecastResult - this contains the next 7 days worth of weather.|
Within <Forecast>, we have the following
This is pretty self-explanatory. Notice the mis-spelt <Desciption>. If you are going to be doing anything by hand, make sure you mis-spell this too!
This should set the scene the way we access this with Clover.
