CARIBOU, ME – A gray dawn spread across the northern Maine sky Saturday, calm and cool but carrying that unmistakable edge of late fall. Leaves cling to branches, but frost glitters over open fields — a quiet signal that colder nights are about to tighten their grip.
According to the National Weather Service in Caribou, temperatures will climb to near 51°F today under increasing clouds. Sunday brings the region’s next shift: a chance of light showers by afternoon as a weak disturbance crosses Aroostook County. Rainfall looks light but steady enough to dampen roads from Presque Isle to Limestone. By Monday, another system brushes the area, with a 40% chance of additional showers through midday before drier, colder air moves in from the northwest.
Drivers should be prepared for slick pavement on Sunday and Monday, especially during early commutes along Route 1 and rural back roads. Once the skies clear late Monday night, temperatures will dip sharply — lows near 28°F could bring the first widespread frost and even patchy freeze risk by early Tuesday. Gardeners are urged to bring in final potted plants, and homeowners should prepare outdoor faucets for the season’s first true cold stretch.
By Tuesday and Wednesday, sunshine returns but with a brisk, biting chill. Daytime highs hover around 50°F, and clear nights will stay cold enough for repeated frost through midweek.
For now, Maine’s fall still holds its quiet beauty — but winter’s edge is quickly drawing near.
A chilly November lies ahead, and this week’s frost is its early warning.
