title: National Weather Service (NOAA) REST API returns nil for parameters of forecast
body: <p>I am using the NWS REST API as my weather service for an app I am making. I was initially reluctant to use NWS because of its bad documentation, but I couldn't resist as it is offered completely free.</p>
  
  <p>Now that I am trying to use it, I am running into some difficulty. When making a request for multiple days, the minimum temperature appears nil for several days.</p>
  
  <p>(EDIT: As I have been testing the API more I have found that it is not always the minimum temperatures that are nil. It can be a max temp or a precipitation, it seems completely random. If you would like to make test calls using their web interface, you can do so here: <a href="http://graphical.weather.gov/xml/sample_products/browser_interface/ndfdBrowserByDay.htm" rel="nofollow">http://graphical.weather.gov/xml/sample_products/browser_interface/ndfdBrowserByDay.htm</a></p>
  
  <p>and here: <a href="http://graphical.weather.gov/xml/sample_products/browser_interface/ndfdXML.htm" rel="nofollow">http://graphical.weather.gov/xml/sample_products/browser_interface/ndfdXML.htm</a>)</p>
  
  <p>Here is an example of a request the minimum temperatures are empty: <a href="http://graphical.weather.gov/xml/sample_products/browser_interface/ndfdBrowserClientByDay.php?listLatLon=40.863235,-73.714780&amp;format=24%20hourly&amp;numDays=7" rel="nofollow">http://graphical.weather.gov/xml/sample_products/browser_interface/ndfdBrowserClientByDay.php?listLatLon=40.863235,-73.714780&amp;format=24%20hourly&amp;numDays=7</a></p>
  
  <p>Surprisingly, on their website, the minimum temperatures are available:
  <a href="http://forecast.weather.gov/MapClick.php?textField1=40.83&amp;textField2=-73.70" rel="nofollow">http://forecast.weather.gov/MapClick.php?textField1=40.83&amp;textField2=-73.70</a></p>
  
  <p>You'll see under the Minimum temperatures that it is filled with about 5 (sometimes less, it is inconsistent) blank fields that say <code>&lt;value xsi:nil="true"/&gt;</code></p>
  
  <p>If anybody can help me it would be greatly appreciated, using the NWS API can be a little overwhelming at times.</p>
  
  <p>Thanks,</p>
