Portland, Maine – Another surge of Arctic air is expected to lock back into Maine during the first full week of February, bringing a renewed stretch of subzero nights and sharply colder-than-normal days that could linger through midmonth.
According to the National Weather Service Climate Prediction Center, temperatures across Maine are favored to run well below normal from Friday through the following Thursday as Arctic high pressure settles over the eastern U.S. At the same time, precipitation probabilities are leaning below average, signaling fewer organized snow systems despite the colder air mass.
The coldest conditions are expected across northern and central Maine, where overnight lows could regularly dip below zero, especially away from the coast. Portland and other coastal communities will see slightly milder readings, but daytime highs may still struggle to climb out of the teens during the coldest stretch early next week. Wind chills could fall below zero statewide during morning and overnight hours.
While colder air often raises snow concerns, the dominant Arctic pattern favors dry air over much of the East Coast and Mid-Atlantic. That setup reduces the likelihood of widespread snowstorms, though fast-moving clippers or offshore systems could still bring light accumulations with limited notice.
Residents are urged to prepare for dangerous cold by protecting exposed pipes, limiting time outdoors, and monitoring updates if the storm track shifts. Additional outlooks and advisories may be issued as the pattern evolves through mid-February.
