To find it, you need to know that tapping on the hourly weather view gives you the temperature graph. Then you need to click the thermostat icon and switch it to precipitation. Only then is the information displayed. Once it's onscreen, the precipitation graph in the Apple Weather app centers on the full day view (with the current time in the middle) rather than just the future, which is what most users care about.
That's not the same as putting it front-and-center. Yes, the information is there, but the interface design is garbage.
