Concord, New Hampshire – Arctic air is expected to remain in control across New Hampshire from Jan. 24 through Jan. 30, bringing an extended stretch of below-normal temperatures and reinforcing harsh winter conditions statewide.
According to the National Weather Service Climate Prediction Center, New Hampshire is placed in a 70 percent probability zone for below-normal temperatures during the Jan. 24–30 period. While not as extreme as farther north, confidence remains high that cold air will persist with limited opportunities for sustained warming before the end of the month.
Across northern New Hampshire, including Coös County and the White Mountains, daytime highs are expected to remain well below seasonal averages, with overnight lows frequently dropping into the single digits or below zero. Prolonged cold will allow snow and ice to remain firmly in place along Routes 16, 2, and mountain corridors.
In central and southern New Hampshire, including Concord, Manchester, and the I-93 corridor, temperatures are also expected to stay below normal throughout the Jan. 24–30 window. Even during brief moderation periods, highs may struggle to climb out of the teens and lower 20s, increasing the likelihood of persistent icy conditions on untreated roads and sidewalks.
New Hampshire emergency management officials urge residents to take cold-weather precautions, including limiting prolonged outdoor exposure, protecting pipes, and checking on vulnerable neighbors and pets.
The Arctic pattern shows few signs of weakening before the calendar turns, and additional cold-related advisories remain possible as confidence stays elevated in below-normal temperatures persisting through the end of January.
