@HFTobeason: I checked your location and it seems wunderground does report 0.71″ precipitation at your location yesterday.
http://api.wunderground.com/api/YOURAPIKEY/yesterday/q/pws:KMAHYANN3.json
just plug in your API key above and you can see that the ‘precipi’ field reports 0.71 (that’s the daily summary). So this is not something we have control over.
