@benwilhelm does Forecast.io provide aggregate precipitation?

ooh looks like these are the ones I care about (from https://developer.forecast.io/docs/v2)

precipIntensity: A numerical value representing the average expected intensity (in inches of liquid water per hour) of precipitation occurring at the given time conditional on probability (that is, assuming any precipitation occurs at all). A very rough guide is that a value of 0 in./hr. corresponds to no precipitation, 0.002 in./hr. corresponds to very light precipitation, 0.017 in./hr. corresponds to light precipitation, 0.1 in./hr. corresponds to moderate precipitation, and 0.4 in./hr. corresponds to heavy precipitation.

precipIntensityMax, and precipIntensityMaxTime (only defined on daily data points): numerical values representing the maximumum expected intensity of precipitation (and the UNIX time at which it occurs) on the given day in inches of liquid water per hour.

precipProbability: A numerical value between 0 and 1 (inclusive) representing the probability of precipitation occuring at the given time.

precipType: A string representing the type of precipitation occurring at the given time. If defined, this property will have one of the following values: rain, snow, sleet (which applies to each of freezing rain, ice pellets, and “wintery mix”), or hail. (If precipIntensity is zero, then this property will not be defined.)

precipAccumulation (only defined on hourly and daily data points): the amount of snowfall accumulation expected to occur on the given day, in inches. (If no accumulation is expected, this property will not be defined.)
