Briefing Alarm News and Weather Not Read Aloud on Galaxy S3
With the tip from Izzy, I was able to determine that the problem was that I didn't have Samsung TTS as my preferred TTS engine.  

To fix this, go to Settings &gt; Language and input &gt; Text-to-speech output, and you can select Samsung TTS there (mine was set to Google Text-to-speech Engine).

EDIT

Well, I was mistaken apparently.  My alarm has reverted back to showing the news and weather and playing my old alarm.  I'm assuming this is a bug at this point, unless someone can find a solution.
