Intensifying low pressure lifted north along the Atlantic coast from the night of the 23rd into the 24th. The slow moving low crossed the Gulf of Maine during the 24th drawing abundant moisture and warmer air aloft  across the region. However...high pressure centered to the north continued to provide low level cold air. The result was a major sleet storm across much of northern and eastern Maine. Varying amounts of freezing rain also occurred. The only area where precipitation remained predominantly snow was across extreme northwest Aroostook county. Precipitation expanded north across the region through the morning of the 24th. Precipitation...mostly in the form of sleet...then persisted through the 24th into the early morning hours of the 25th. Warning criteria sleet accumulations occurred through the afternoon into the evening hours of the 24th. Storm total sleet accumulations across much of northern Maine ranged from 2 to 4 inches...with local totals up to around 5 inches.  Sleet accumulations of 1 to 3 inches were common across interior Downeast areas. Freezing rain accumulations across the region were generally 0.25 inch or less...though locally greater totals were reported.
