Forecast by Observed Snowfall Scatterplots for Top 4 Forecasts
Forecast/s dotted BLUE line below (above) the Observed snowfall/s solid RED line ==> under (over) forecast error.
R^2: how well the forecast model 'explained' the variability of the observed snowfall (i.e., an R^2 of 0.710 means the forecast model explained 71% of the observed snowfall's variability).

Comparison of Top 4 Forecasts and Observed Snowfall by Station
Forecast Skill Score (measured against NWS ER WFOs)
- Positive (negative) SKILL values indicate the degree of a forecast/s improvement (degradation)
compared to NWS forecasts.
Bias: the arithmetic difference between the average Forecast snowfall and the average Observed snowfall (avgForecast - avgObserved).
