New Hampshire starts the day under clear skies and biting cold, but winter momentum is building.
By Sunday, December 14, light snow may move into the Manchester area, bringing early-season travel concerns and reinforcing December’s grip.
According to the National Weather Service, clouds increase Saturday as temperatures rise into the mid-30s. That mild bump sets the stage for a possible rain-to-snow changeover late Saturday into Sunday. Snow chances remain around 30 percent, but even brief snowfall could impact roads as colder air quickly follows.
Temperatures fall back toward freezing Sunday, with highs near 29°F. That shift raises the risk of black ice, especially where daytime moisture lingers. Side streets, bridges, and shaded roads may become slick by Sunday morning. Drivers should slow down and allow extra time if traveling.
Meteorologists are watching a broader winter pattern across the Northeast. Arctic air continues pressing south, reinforcing a cold snap that locks in wintry conditions into early next week. While this system does not signal heavy snow, it serves as an early sign of winter’s arrival in southern New Hampshire.
Winds ease compared to earlier in the week, but cold air deepens Sunday night. Lows fall near 11°F, allowing any untreated surfaces to refreeze quickly. Outdoor plans and early holiday travel should factor in sharply colder mornings.
This setup marks the transition into true winter weather season. Conditions may change fastest before sunrise Sunday and again after sunset.
