Manchester, NH – A colder and more active weather pattern is setting up across New Hampshire from Nov. 29th through Dec. 5th, increasing the potential for early-season snow in the north and cold rain in the south as winter conditions expand across the state.
According to NOAA’s Climate Prediction Center, temperatures during this period are expected to trend below normal statewide, including southern areas such as Manchester, central cities like Concord, and northern regions including Berlin and the White Mountains. Interior and northern zones may see overnight lows falling well below freezing, boosting the chance for accumulating snow whenever storm systems track through.
NOAA also highlights a strong signal for above-normal precipitation across New Hampshire. This indicates several disturbances may move through the region, bringing cold rain to southern counties and snow or mixed precipitation to central and northern areas.
Manchester and neighboring southern communities, including Nashua and Derry, are most likely to experience chilly rain, though a brief rain-to-snow transition is possible if temperatures dip at the right time. Northern and higher-elevation areas — including the White Mountains, North Conway, and Coös County — hold the highest probability for accumulating early-winter snowfall.
Forecasters emphasize that no singular major winter storm is highlighted at this range. Instead, the pattern favors a series of weaker systems, each capable of producing slick roads, reduced visibility, and travel delays — particularly on I-93, Route 3, and mountain passes leading into northern New Hampshire.
As December begins, residents across New Hampshire should monitor local forecasts closely for shifting rain-snow lines.
