CARIBOU, Maine – Fog clings thick to the fields of Aroostook County this morning, rolling across highways and dimming headlights to halos in the gray dawn. The air feels damp and cool, a calm before a much wetter stretch that will soak northern Maine early this week. As visibility dips under a quarter mile in spots along Route 1 and Route 89, drivers should allow extra time and keep low beams on through the morning hours.
According to the National Weather Service in Caribou, conditions will gradually clear this afternoon as light southeast winds bring slightly warmer air. Highs will climb to the lower 60s under filtered sun, but the brief calm won’t last. By late Monday night, a stronger system approaches from the Great Lakes, spreading rain and patchy fog across the region through Tuesday and Wednesday.
Forecasters expect the heaviest rain Tuesday evening into early Wednesday, when 1 to 2 inches of precipitation could fall across northern Maine. Saturated soil may cause brief ponding on rural roads, especially in Caribou, Presque Isle, and Fort Kent. Southeast winds could gust near 25 mph at times, adding to the chill and making umbrellas a challenge.
By Thursday, the storm exits east, leaving behind cooler, drier air and clearing skies. Temperatures will slide into the 30s by Friday morning — the first sign of frost possible in sheltered valleys as fall edges toward its colder half.
After a gray, foggy start, Maine’s far north is bracing for a wet few days before the crisp calm of late October returns.
