Accounting for forecasted weather

Are there any plans to account for forecasted precipitation in a weather adjustment method? I understand that’s a pretty tall order on account of the inherent volatility in weather forecasts, but I hate to hear my system running overnight when the forecast calls for very high probability of rain in the next day or two.

An easier method might be to at least account for irrigated water along with precipitated water, such that if the system were to run in short advance of significant actual precipitation, the next cycle factor would be decreased accordingly. Is this perhaps how ET adjustment works? Pardon my ignorance on this matter.
