Portland, Maine – Arctic air is expected to remain firmly entrenched across Maine through the end of the month, bringing prolonged cold and reinforcing winter conditions statewide.
According to the National Weather Service Climate Prediction Center, Maine sits within a high-confidence zone for below-normal temperatures through the remainder of the month, with probabilities leaning as high as 80 percent across northern and interior sections of the state. The persistent pattern reflects repeated intrusions of Arctic air and limited opportunities for meaningful warm-ups.
Across northern Maine, including Aroostook County and areas near the Canadian border, daytime highs are expected to remain well below seasonal averages, with overnight lows frequently dropping into the single digits or below zero. The sustained cold increases the risk for icy roads, frozen pipes, and stress on heating systems, particularly in rural communities.
In central and southern Maine, including Bangor and the Portland metro area, temperatures are also expected to stay below normal, even during brief moderation periods. Highs may struggle to climb out of the teens and 20s at times, allowing any snow or ice on roads such as Interstate 95, Route 1, and Route 202 to linger.
Maine emergency management officials urge residents to take cold-weather precautions, including limiting time outdoors, checking on vulnerable neighbors, and ensuring pets and livestock are protected from the cold.
The Arctic pattern shows little sign of breaking before the calendar turns, and additional cold-related advisories or warnings may be issued as confidence remains high in sustained below-normal temperatures across Maine.
