We are throwing PHP fatal errors when we have trouble parsing the warnings ATOM feed from the National Weather Service.

We need to check XML validity and, in the event of bad data, discard and try again on the next regular update cycle. In the mean time, we can continue spitting out warnings from the cache.

Example errors:

19-Aug-2014 10:18:12 America/New_York] PHP Fatal error: Uncaught exception 'Exception' with message 'String could not be parsed as XML' in getweather.php:263
Stack trace:

Implemented proper error handling for any XML errors that occur, either in the warnings or in the NWS forecast/conditions data.
