The neural network was designed using rawinsonde data and Eta model forecasts for Omaha, Nebraska from 355 days during the warm seasons (May 1 - September 30) of 1998-2000. Observed precipitation amounts were taken as an average of several sites in the Omaha area. A network trained on 50% of the cases evidences a high degree of forecast skill for heavier rainfall amounts. Light amounts (generally .25 inches or less in 24 hours) tend to be overforecasted, with high probabilities of detection but also high false alarm rates. Heavier rainfall amounts (.5 or 1.0 inches in 24 hours) are somewhat underforecasted, with nearly perfect false alarm rates (near zero). A preliminary comparison with rainfall forecasts from a 10 km version of the NCEP Eta model suggests that the neural network system is more skillful for the heavier rainfall amounts (.5 inches or more). For instance, for rainfall exceeding 1.0 inches, the equitable threat score (ETS) of the neural network system is .39, whereas the 10 km Eta model has an ETS of .08. The correlation of predicted amounts with those observed is much better in the neural network than in the standard grid point Eta model.
