Winter '16 / '17 - 18th Annual 'Regular Season' Snowfall Forecast Contest: FINAL Results

Four contest-worthy storms this season.  Tied with Winter '05 / '06 for 15th place.
Under the ‘two-thirds’ rule … forecasters who entered at least THREE forecasts are included in this season's FINAL standings..

SUMSQ is the primary measure of forecaster skill (lower the better).

Top 5 Forecasts (Error statistic:  Total Absolute Error - TAE)
TAE is the secondary measure of forecaster skill (lower the better).

Top 5 Forecasts (Error statistic:  RSQ)
RSQ is a supplementary measure of forecaster skill (higher the better).
Accounts for how well the variability of the observed snowfall was accounted for by the forecast.

Hope to see y'all again next winter.
