1. A method comprising: ingesting, as input data, weather information, crop-specific information for a stored grains crop, and grain storage facility information, the weather information including recent and current field-level weather data and extended-range weather forecast data, the crop-specific information including at least one of crop type data, crop post-maturity dry-down characteristics, crop airflow characteristics, and targeted crop moisture or temperature thresholds, and the grain storage facility information including at least one of grain storage facility dimensions data and grain storage facility airflow data; modeling the input data in a plurality of data processing modules within a computing environment in which the plurality of data processing modules are executed in conjunction with at least one processor, the data processing modules configured to profile moisture content of the stored grains crop relative to impacts of time-varying weather conditions, in-bin drying characteristics, and existing crop moisture conditions on an equilibrium moisture content of a grains crop stored in a grain storage facility, by 1) diagnosing and predicting expected weather conditions impacting energy requirements for in-bin drying of the stored grains crop at a specific location, and 2) applying the expected weather conditions, the crop-specific information, and the grain storage facility information to an agricultural model of one or more physical and empirical characteristics impacting a rate of forced-air ventilation of the stored grains crop to simulate time-varying moisture content of the stored grains crop at specific times and predict a rate of forced-air ventilation for the stored grains crop at the specific location over time; and generating, as output data, a rate of forced-air ventilation to achieve a desired moisture content in a harvest output condition profile.
