Precipitation for History returns -9999% (U.S.)

I've been trying to pull the Historical Data for precipitation, but doesn't return valid.

Overview:
I'm currently coding a daily hourly forecast (similar to the way wunderground.com has for searched areas). Meaning the hourly forecast needs to retain the daily forecast. The API for Hourly Forecast only returns the future forecast and doesn't retain the Daily Hourly Forecast. This means I have to check the time and pull from the History forecast in order to punch in the data that the Hourly Forecast removes.

Problem:
When I pull the data from History, Precipitation returns as "-9999%". I don't understand why these values would be used in Hourly Forecast but not be available in the History. Am I missing something here? I also need to pull Cloud Coverage (supported in Hourly but not History?). Help!
