Manchester, New Hampshire – A broad warming trend is poised to take hold across New Hampshire as February closes out, raising the probability that winter’s sharpest cold retreats during the Feb. 28 through Mar. 13 period.
According to the National Weather Service Climate Prediction Center, New Hampshire carries a 33% to 50% chance of above-normal temperatures in the Week 3-4 outlook. That signal covers the entire state, including the White Mountains, the Lakes Region and the Seacoast, and reflects a larger-scale warm pattern expanding across much of the eastern United States.
The extended-range data points toward more seasonable to slightly milder conditions compared to late-winter averages. While colder stretches remain possible, long-range guidance suggests fewer prolonged Arctic outbreaks impacting major travel corridors such as Interstate 93, Interstate 89 and Interstate 95.
Precipitation probabilities during the same timeframe lean near normal across New Hampshire. No strong wet or dry anomaly stands out, meaning typical late-winter systems remain possible without a clear indication of excessive snowfall or drought concerns.
Communities including Manchester, Concord, Nashua, Portsmouth and Berlin fall within this broader transition signal. This outlook highlights large-scale atmospheric trends rather than specific storm timing or day-to-day details.
Updated guidance is expected as the late-February to mid-March window approaches, with refinements likely as shorter-range data becomes available.
