Manchester, New Hampshire – A colder, storm-supportive pattern is setting up across New Hampshire, prompting a December Snow Alert as winter in Manchester turns more active heading into mid-month. While it’s too early to determine exactly how many inches of snow could fall, one thing is certain: New Hampshire is positioned for an above-average amount as the pattern shifts colder and wetter.
According to the Climate Prediction Center, much of northern New England leans colder than normal through December, with near- to above-normal precipitation favored. According to the National Weather Service in Gray, this combination often signals a busier winter stretch with clippers, coastal systems, and shortwaves capable of producing several rounds of accumulating snow. Early signals point to multiple storm windows during the second week of December and again closer to the holidays.
According to NHDOT, travel hazards will increase along I-93, the Everett Turnpike, and higher terrain routes including Kancamagus Highway and Route 302. Black ice, reduced visibility, and quick bursts of heavy snow could complicate the morning commute. Motorists should keep winter kits ready, charge devices, and leave extra time for travel, especially on untreated surfaces before sunrise.
Holiday parades, school events, and weekend shopping could encounter weather impacts if storm systems align with evening or overnight periods. Residents should dress in layers, secure outdoor decorations, and prepare for brief power outages when wetter snow builds on tree limbs and lines.
While snowfall totals cannot yet be pinned down, long-range indicators continue to support a colder and storm-prone pattern — strengthening the likelihood of a snowy December in New Hampshire and increasing the chances of a White Christmas for many towns across the state.
