An irrigation system for an area receives wide-area meteorological prediction data and sensors deployed within the area collect local-area sensor data. A processor stores received data as historical wide-area meteorological prediction data and data from the sensors as historical local-area sensor data. The processor determines a relationship between the historical wide-area meteorological prediction data and the historical local-area sensor data based on the historical wide-area meteorological prediction data and the historical local-area sensor data, and calculates a prediction on a local-area parameter for a future point in time based on current wide-area meteorological prediction data, and the calculated relationship. The area is then controlled based on the prediction.
