Bangor, Maine – Snow begins falling across the Bangor region by 10 p.m. Tuesday, and roads along I-95 and Route 9 could turn slick within minutes as temperatures hover near freezing.
According to the National Weather Service in Caribou, steady snow will overspread central and Downeast Maine overnight, with the heaviest stretch between midnight and 7 a.m. Wednesday. Most of the Bangor area is expected to pick up 2 to 4 inches by late Wednesday morning, with snowfall rates occasionally nearing 1 inch per hour before daybreak.
The Wednesday morning commute along I-95, I-395 and US-1 could slow significantly as untreated pavement becomes snow-covered. Crews from the Maine Department of Transportation are expected to treat major corridors, but secondary roads in Brewer, Orono and Ellsworth may remain slippery through midmorning. Drivers should allow extra stopping distance and avoid sudden lane changes on bridges and overpasses, where surfaces cool fastest.
Snow tapers from southwest to northeast late Wednesday morning as temperatures gradually climb above freezing during the afternoon. That warming trend limits additional accumulation and begins melting on main roadways, though shaded areas could stay slick.
Farther north toward Presque Isle and northern Aroostook County, lighter snow may linger into late Wednesday night or early Thursday.
Another shift arrives by Saturday, when a warmer system pushes rain into the region, changing any mixed precipitation to plain rain and accelerating snowmelt.
Travel impacts will be most noticeable through 9 a.m. Wednesday. Additional advisories may be issued if snowfall rates increase overnight.
