Caribou, Maine – A gray dawn settles over northern Maine this Thursday, mist clinging to low fields and damp roads. A few light showers sweep across the Aroostook River Valley, marking the start of a slow-moving weather shift — one that will usher in much colder, more seasonable air by the weekend.
According to the National Weather Service in Caribou, scattered showers will linger through midday Thursday before partial clearing late. Afternoon highs will hold near 57°F, but behind this weak system, a drier and cooler pattern takes hold. Winds ease Thursday night, and patchy fog could form as skies briefly clear.
By Friday, the region dries out under partly sunny skies with highs in the low 50s. The real chill comes Friday night, when lows dip into the mid-30s, possibly reaching freezing in the coldest valleys. Saturday morning may bring the first light frost of the season in open fields across rural Aroostook County. Residents finishing fall chores should protect tender plants and wrap up outdoor plumbing this week.
The weekend stays crisp and bright, perfect for late foliage drives or early Halloween decorating. Highs Saturday and Sunday hover around 49–47°F, with a chance for scattered showers returning late Sunday as another weak disturbance passes through.
Looking beyond, models hint at a sharper drop in temperatures early next week — possibly the first true cold snap of the season. As Maine edges closer to November, the region’s early-winter rhythm is beginning to take hold.
