The episode as NWS CAR wrote it up.
Low pressure tracking across southern Maine to the maritimes brought a wintry mix of precipitation to northern Maine during Thanksgiving. The precipitation started in the form of snow during the early morning hours...then eventually mixed with sleet...freezing rain and rain before ending. Snow accumulations of 4 to 8 inches occurred across northern portions of Aroostook county...with the heavier accumulations generally across northern and higher terrain areas. Sleet and freezing rain accumulations ranged from one-quarter to three-quarters of an inch. The combination of snow and ice broke some tree limbs which fell on power lines contributing to scattered power outages.
