On December 16-17, 2020, a Nor’easter left behind a large footprint of double-digit snowfall totals across the interior Mid-Atlantic and Northeast regions. The heaviest snow fell in a narrow band thatstretched from north-central Pennsylvania to far southeastern Maine. Snowfall totals in excess of 30 inches were reported in this mesoscale snowband with localized amounts exceeding 40 inches across theSouthern Tier of New York, southern Vermont and New Hampshire. Numerous snowfall records were set with this storm including a new storm-total snowfall of 40” at Binghamton, New York. While the sheeramount of snow was extraordinary by itself, the short duration and intense snowfall rates adds to the remarkability of this event. Snowfall rates of 4 to 6 inches per hour for much of the night and earlymorning on 17 December resulted in snowfall totals near three feet in 12 hours. This amount of snow in a short period of time caused roads to become nearly impassible as snow plows could not keep up andeven in some instances became stuck.
