A method and system for determining cloud seeding potential comprises receiving a temperature and a liquid water content (LWC). A seeding index is calculated based on the temperature T, a temperature membership function ƒ；(T), the LWC, and a liquid water content membership function ƒ；(LWC) at the plurality of grid points to create a seeding index set. A target region potential flag is set based on the seeding index set.
