WRF Model Comparison Eastern Nebraska/southwest Iowa 21Z 10 June 2005 Temperatures
- NMM5: The NMM5 model did a great job of forecasting the temperatures. It not only predicted the temperatures measured at 21Z within one or two degrees, it also was the only model to accurately anticipate a small area of warmer temperatures in northwestern Iowa. (RANK 1)
- EM5: The calculations of the EM5 model for 21Z were quite a bit off the mark. It predicted that the temperatures in eastern Nebraska and western Iowa would range from the mid 80s to the lower 90s. However, the warmest temperature in the area, Storm Lake, Iowa, only reached 81 degrees. (RANK 3)
- ARW: The ARW model was fairly accurate in forecasting the temperatures at 21Z. Like the NMM5 model, its predictions were within one or two degrees of the actual measurements. However, the ARW model failed to recognize the small area of warmer temperatures in northwestern IA. (RANK 2)
