Description:
Monthly threat scores day 1, 24-hour accumulated precipitation for GFS and WRF-NMM numerical weather prediction models, compared to human forecasts from Hydrological Prediction Center of the U.S. National Weather Service for the period August 2008 through August 2009. Human forecasters consistently beat the numerical models, but the month to month threat scores move for all in tandem, illustrating the dependence of human forecast skill on numerical model guidance.
