Low pressure tracking along a stalled frontal boundary across Downeast Maine brought abundant moisture to the region.  Across northern portions of the region rain transitioned to snow during the evening of the 6th with colder air in the wake of the front. Across central portions of the region...just north of the stalled front...low levels cooled while the low drew warmer air aloft over the frontal boundary. This resulted in snow and sleet transitioning to freezing rain. Snow north...with mostly freezing rain across central portions of the region...then continued through the afternoon of the 7th. Storm total snow accumulations of 15 to 20 inches were common across northern portions of Aroostook...Piscataquis and Somerset counties...with totals of around 24 inches across extreme northwest areas. Storm total snow accumulations in a zone from southeast Aroostook county...across northern Penobscot county...to central and southern Piscataquis county varied significantly. Snow accumulations across northern portions of this zone generally ranged from 8 to 14 inches...with 2 to 6 inches across the remainder of the region where a greater portion of the precipitation fell in the form of sleet and freezing rain. Ice accumulations of 1/4 to 3/4 of an inch were common...with localized totals of around 1 inch. South of the frontal boundary...across Downeast Maine...enough warm air was drawn into the storm to allow most of the precipitation to fall in the form of rain.
The combination of heavy wet snow and significant ice accumulation snapped branches...toppled and weighed down many trees. The falling trees and branches...along with ice build up on wires...brought down numerous power lines contributing to power outages. The most numerous power outages occurred in a zone from southern Piscataquis county....across central and northern Penobscot county...to southeast Aroostook county. Thousands of customers lost power for varying amounts of time in this zone...some without power for over 24 hours. Fallen trees and power lines also blocked roads in some areas.
