Caribou, ME – The sharp edge of winter is cutting into northern Maine this week as an arctic cold front barrels south, promising snow, wind, and extreme cold. By Friday morning, wind chills could plummet to a staggering -25°F to -30°F across the far northern tier, leaving even short trips outdoors dangerous.
According to the National Weather Service in Caribou, the first wave of snow will arrive Thursday morning with bursts of heavy snow and blowing drifts through late day. Accumulations of 3 to 6 inches are possible, with localized snow squalls reducing visibility to near zero along Route 1 and rural roadways across Aroostook County. Travel may become treacherous by Thursday afternoon as temperatures freefall.
Behind the snow, bitter arctic air will grip the region into the weekend. Friday’s high may struggle to reach 14°F, and exposed skin can freeze in minutes during the morning commute. Residents are urged to limit outdoor exposure, check on vulnerable neighbors, and ensure pets are brought indoors. Black ice and frost may reform on plowed roads as daytime melting refreezes quickly after sunset.
The weekend will remain frigid but mostly clear, with slightly milder air returning by Sunday. Early signs hint at another system early next week that could bring light snow or a wintry mix across interior Maine.
Bundle up and plan ahead — winter has arrived in force across the North Woods.
