What happened

The episode as NWS CAR wrote it up.

Intensifying low pressure tracking across the Gulf of Maine to Nova Scotia brought the first significant snow of the season to portions of Downeast Maine...east-central Maine and the central Maine highlands. Snow began during the night of the 29th...then persisted through the morning of the 30th.|The heaviest snow accumulations occurred in a line from southern Piscataquis county...across central Penobscot county to northern Washington county and portions of southeast Aroostook county. Accumulations in this band generally ranged from 5 to 8 inches...with localized totals to around 10 inches. Accumulations across Downeast Maine varied significantly...ranging from less than an inch up to 7 inches.|Temperatures remained above freezing through much of the storm...leading to a heavy wet snow which weighed down branches and power lines. The heavy wet snow combined with wind gusts of 40 to 50 mph along the coast and 30 to 40 mph inland to snap branches...topple trees and bring down power lines. Thousands of customers lost power for varying amounts of time during the storm.
