Abstract: Methods and systems for predicting airport capacity impact using a probabilistic weather forecast are disclosed. A method includes: receiving, by a computing device, a probabilistic weather forecast including a plurality of weather scenarios; determining, by the computing device, an airport capacity prediction for each of the plurality of weather scenarios included in the probabilistic weather forecast; clustering, by the computing device, the airport capacity predictions; and generating, by the computing device, at least one aggregated airport capacity prediction using the clustered airport capacity predictions.
