The author is grateful to Bob Glahn, Matt Peroutka, John Wagner, and two anonymous reviewers for useful suggestions. The author acknowledges Tony Eckel who suggested including a spread-skill-based calibration technique within EKDMOS. This work was made possible by the Statistical Modeling Branch of the Meteorological Development Laboratory, which maintains an archive of quality controlled station observations. The operational ensemble forecasts furnished by NCEP and the CMC were also invaluable for this work.
