Description: A Bias-corrected Root Mean Square Error (BCRMSE; solid line) score of 0.0 represents highly skillful 2-m dewpoint forecasts across the western contiguous United States. A Mean Error (ME; dashed line) of 0.0 represents forecasts that are neither too moist nor too dry. The y-axis represents the BCRMSE and ME in °F, and the x-axis represents the number of hours between the forecast issuance and valid times (i.e., lead time). Different colored lines represent different models, according to the legend. The grey numbers above the plot represent the number of forecasts used to calculate BCRMSE and ME.
