This paper is based on work funded by the National Oceanic and Atmospheric Administration under Award NA67WD0486, “Probabilistic Hydrometeorological Forecast System.” Results reported herein were first presented at a workshop held with the senior forecasters of the Hydrometeorological Prediction Center in Camp Springs, Maryland, on 27–28 February 1997. Insightful discussions are acknowledged with William Drzal, Thomas Graziano, James Hoke, Norman Junker, Brian Korty, Theresa Rossi, Bruce Terry, Erich Wolf, and Sondra Young.
