Provides NDFD forecasters and users with feedback regarding the skill and accuracy of gridded NDFD forecasts through a verification system consisting of a combination of traditional point verification plus grid comparisons. The NDFD forecasts are compared to Global Forecast System (GFS)-based MOS (both point- and grid-based guidance), National Blend of Models (NBM, or Blend), and NCEP's Weather Prediction Center (WPC) forecasts whenever possible.
