Concord, New Hampshire – A notably colder weather pattern expected to take hold across New Hampshire between Tuesday and Saturday is increasing concern for snow and potential travel impacts statewide. While confidence in exact storm timing remains limited, the strength of the cold signal raises the likelihood that any systems passing through during this period could produce accumulating snow.
According to the National Weather Service Climate Prediction Center, New Hampshire carries a 60–70% probability of below-normal temperatures during the January 20–24 window, pointing to a sustained stretch of cold air. At the same time, precipitation probabilities lean above normal at 40–50%, a setup that favors snow as the dominant precipitation type across much of the state.
In Concord and central New Hampshire, daytime temperatures are expected to remain suppressed, with overnight lows dropping well below freezing. That environment supports efficient snow accumulation even with moderate moisture. Farther north and across higher terrain, including the White Mountains and surrounding foothills, the risk for more substantial snowfall increases if storm tracks align favorably.
Major travel corridors such as I-93, I-89, Route 3, and Route 16 could become slick during snow periods, particularly overnight and during the early morning commute. Cold pavement temperatures may allow snow and ice to linger between systems, compounding travel hazards. Prolonged cold may also increase energy demand and place added stress on home heating systems.
Residents are urged to prepare ahead of the Jan 20–24 period by checking heating equipment, insulating exposed pipes, and ensuring vehicles are stocked with winter emergency supplies. While significant snow is not guaranteed, the evolving pattern supports the potential for at least one impactful winter weather event.
This cold-driven setup is expected to persist through late week, and confidence may increase as individual systems come into sharper focus. Additional winter weather advisories or alerts could be issued as conditions warrant.
