CARIBOU, MAINE – Northern Maine will wake up to patchy frost and crisp sunshine this weekend before a strong fall storm system brings widespread rain by early Monday. Residents across Aroostook County should plan for a big shift from cold, quiet mornings to wet and windy afternoons as the new workweek begins.
Temperatures dropped near freezing early Saturday, signaling the start of another classic Maine cold snap. The National Weather Service in Caribou notes frost could still form in sheltered valleys early Sunday. Drivers along Route 1 should be cautious during early travel hours, as frost may linger on bridges and shaded roadways. Sensitive plants and late fall gardens should be protected or brought indoors through the weekend.
By Sunday afternoon, clouds increase as warmer air pushes in from the south. Expect highs near 61°F Sunday before rain spreads into the region Monday. The heaviest rainfall arrives late Monday and continues through Tuesday, when gusts up to 25 mph may accompany steady rain. Totals could reach an inch or more, with ponding possible on rural roads and low-lying fields.
After the early-week rain, cooler, breezy conditions return midweek. Highs dip back into the 50s by Thursday, keeping the late-October chill alive. Those planning outdoor chores, pumpkin patch trips, or leaf viewing should take advantage of Saturday’s sunshine—wet weather dominates much of next week.
