A probability of precipitation equation for Columbia, South Carolina derived from logistic regression

"While probability of precipitation (PoP) forecasts are generated from the aviation (AVN) and nested grid (NGM) models for operational use, centralized PoP guidance from the Eta model is not available. Interest thus arose in developing a local PoP equation by using Eta model data as predictors. We also developed PoP equations by utilizing predictor variables taken from both the Eta and NGM models to examine the merits of combining information from different models in a statistical forecast system. The goal in deriving local PoP equations was to produce statistical forecast guidance competitive with the centrally produced, Model Output Statistics (MOS) guidance that would also be easy for forecasters to use in an operational setting"--Introduction.
