CARIBOU, Maine — Northern Maine woke to a muted, steel-gray Saturday, calm and seasonably cool, with a silver sparkle of frost on open fields hinting that colder nights are closing in.
The National Weather Service in Caribou expects today’s high to reach about 51°F as clouds steadily thicken. Sunday marks the next change: a weak disturbance sliding across Aroostook County should trigger light, on-and-off showers by afternoon. Rain totals look modest but enough to dampen roads from Presque Isle to Limestone. Another passing system brushes the area Monday, bringing around a 40% chance of additional showers through midday before drier, colder northwest air settles in.
Travelers should plan for slick spots Sunday and Monday, particularly during early commutes along Route 1 and across rural back roads. As skies clear late Monday night, temperatures will tumble; lows near 28°F could deliver the season’s first widespread frost and even a few patchy freeze pockets by early Tuesday. Gardeners should bring in any remaining potted plants, and homeowners would be wise to winterize outdoor spigots ahead of the first real cold snap.
Sunshine returns Tuesday and Wednesday, but the air turns brisk. Afternoon highs hover near 50°F, while clear nights remain cold enough for repeated frost through midweek.
Autumn’s quiet charm still holds over northern Maine, but the leading edge of winter is drawing close. A chilly November appears likely, and this week’s frost is an early heads-up.
