Explosively intensifying low pressure tracked across the Gulf of Maine to the Maritimes during the 25th. The low brought heavy snow to much of the region. Snow developed across the region through the early morning hours of the 25th then persisted into the afternoon. Snow rates of 1 to 3 inches per hour at times occurred across Downeast areas along with thunder snow. Warning criteria snow accumulations occurred from the late morning into the early afternoon hours. The heaviest storm total snow accumulations occurred in an area from Bangor...to Topsfield...to Houlton and Greenville with generally 10 to 17 inches. Accumulations across much of the remainder of northern Maine ranged from 6 to 11 inches...though lesser totals occurred across extreme northwest areas. Wind gusts of 30 to 40 mph produced extensive blowing and drifting snow. A transition to a wintry mix and rain limited snow accumulations along the Downeast coast.
