Caribou, ME – Northern Maine is preparing for a round of heavy, wet snow this weekend, and forecasters say the biggest impacts will fall north of the I-95 corridor as a Sunday-into-Monday storm moves across the region.
According to the National Weather Service in Caribou, snow is expected to begin late Saturday night into early Sunday morning, with most locations north of I-95 holding a 60–90% chance of receiving at least four inches. Areas such as Patten, Clayton Lake, St. Zacharie, and Estcourt show some of the highest probabilities in the latest forecast guidance.
Precipitation onset varies by location, but most of northern and central Maine will see snow begin between 1 a.m. and 3 a.m. Sunday, spreading steadily through the morning. Snowfall will continue into Monday morning as colder air remains locked in across the interior.
Forecasters say winds will pick up early Monday, which may lead to periods of blowing snow and reduced visibility during the morning commute. Icy patches are likely, particularly on untreated secondary roads and elevated surfaces.
The National Weather Service notes that this system will bring the heaviest totals to far-northern Aroostook County, while locations farther south—including Bangor, Bar Harbor, and Calais—show lower probabilities for significant accumulation.
Drivers traveling I-95 from Bangor to Houlton Sunday night into Monday should anticipate slower travel conditions and potential slick spots.
A Winter Storm Watch has been issued for northern Maine as confidence grows in impactful snowfall.
Residents are encouraged to monitor updated forecasts throughout the weekend.
