Intensifying low pressure tracked northeast from the mid Atlantic region early on the 27th...crossing the Gulf of Maine that night...then exiting through the maritimes early on the 28th. Snow began to develop across southern portions of the forecast area during the early morning hours of the 28th...then expanded across the rest of the region through the remainder of the morning. Warning criteria accumulations were met through the afternoon into the evening hours of the 27th. The snow then ended during the early morning hours of the 28th.
Storm total snow accumulations across Downeast areas generally ranged from 6 to 12 inches...with localized totals up to 14 inches. The snow did mix with sleet at times contributing to the range of snow totals. Along the immediate Downeast coast precipitation even transitioned to all rain for a time...though just inland from the coast snow and sleet persisted. This created a sharp snow gradient from the immediate coast to slightly inland from the coast. The combination of heavy wet snow and gusty winds did bring branches down on power lines contributing to power outages across Downeast areas.  Snow totals across much of the rest of the region generally ranged from 9 to 15 inches...with localized totals up to 17 inches across southeast Aroostook county. Lesser totals of 5 to 8 inches occurred across extreme northeast Aroostook county. Occasional wind gusts of 40 to 50 mph occurred along the Downeast coast...with gusts of 25 to 35 mph across the remainder of the region. The winds produced significant blowing and drifting snow with near blizzard conditions at times.
