BANGOR, Maine — Just in time for the morning commute, parts of eastern and coastal Maine are expected to wake up Monday to the first snowfall of the year.

“It is going to start as rain this evening and around midnight will change to snow,” Maureen Hastings, a forecaster for the National Weather Service in Caribou, said Sunday afternoon.

Mainers living from Houlton to Ellsworth and Down East can expect to be hardest hit, with about 2 to 4 inches of snow, while northern and western Maine will see 1 to 2 inches, she said.

“Isolated areas, mostly in Washington County, may see 5 inches,” Hastings said.

The snow is expected to taper off late Monday morning or by early afternoon, the forecaster said.

With wet roads and the possibility of black ice, Hastings urged caution for drivers who could see less than ideal driving conditions overnight and during the Monday morning commute.

While eastern and coastal parts of the state may see their first snowfall, Aroostook County saw its first snowfall Oct. 17, from 4.8 inches west of Dyer Brook to an inch and a half in Caribou, according to a previously published report.

According to the National Weather Service in Caribou, the state has only three times gone this late into November without measurable snowfall — in 1957, 1994 and 2011.
