A winter storm could dump more than a foot of snow over much of northern Maine while coating the coast with an icy mix through Friday night.
The National Weather Service has issued a winter storm watch for nearly the entire state Thursday morning into late Friday night.
“Travel could be extremely dangerous. The hazardous conditions could impact the morning and evening commute,” a weather service advisory read.

Heaviest snow accumulation was expected in Aroostook County, where up to 12 to 18 inches could fall from Madawaska in the St. John Valley to Houlton in the south and Clayton Lake in the west, the weather service’s Caribou office said Wednesday morning.
In Penobscot County, Millinocket was forecast to see up to 8 to 12 inches of snow, while Lincoln was expected to receive up to 8 inches, according to the weather service.
Greater Bangor was forecast to see 4 to 6 inches of accumulation. Snowfall was expected to taper toward the coast, where 3 to 4 inches could fall from Bar Harbor to Eastport, the weather service said.
Closer to the coast, the weather service said the Penobscot Valley and coastal Hancock and Washington counties could see up to three quarters of an inch of sleet and two-tenths of an inch of ice. It was unclear Wednesday morning how far north that mixed precipitation would extend, according to the weather service.
“Significant uncertainty still exists regarding how far north mixed precipitation will reach and decrease snow totals,” the weather service’s Caribou office said in a tweet.
