Congratulations to Donald Rosenfeld for his 1st Place finish.
Donald also placed first in '05 / '06 and '12 / '13.
Forecasters ranked by their total absolute error.

Season-total snowfall from all stations (784") came in 14% below the period-of-record normal (914").
Winter '18 / '19 ranks 11th among other Contest years since winter '04 / '05 ... the season when BGR and BGM were added to the station list.

Apologies for the abbreviated recap.
Will add to the pile a little at a time this week including each forecaster's station-by-station verification.
