March is shaping up to be a rollercoaster of weather in New Hampshire, bringing everything from late-season snowstorms to mild, rainy spells. While winter isn’t quite ready to loosen its grip, signs of spring will gradually emerge, creating a month of rapid weather swings and unpredictable conditions.
Winter Holds On – But Not for Long
The first part of March will remind New Hampshire residents that winter isn’t over yet. A series of snowy periods will sweep across the region, bringing on-and-off snow showers and colder-than-normal temperatures. The biggest concern is the potential for one or two late-season winter storms, which could dump several inches of snow in a short period. While the snow won’t be as frequent or as intense as in the dead of winter, March snowfalls are often heavy and wet, which can lead to slippery roads and potential power outages. Residents should keep their winter gear handy, as the first two weeks of March will still feel more like mid-February than early spring.
Rain Takes Over as Temperatures Climb
By mid-March, a noticeable shift will occur. Temperatures will rise, and precipitation will transition from snow to rain. This change is expected between March 9 and March 12, with forecasters predicting several rounds of rain showers accompanied by temperatures in the upper 40s and low 50s. This shift to milder, wetter weather means melting snow and rising water levels, increasing the risk of localized flooding in low-lying areas. Rain combined with melting snow can quickly overwhelm drainage systems, so residents should be prepared for ponding on roads and overflowing streams.
Spring Tries to Make an Appearance
As we head into late March, daytime highs will consistently reach the 50s, and for the first time in months, some parts of New Hampshire may even see temperatures nearing 60°F. This will lead to longer-lasting dry spells and the first real glimpses of spring. However, don’t put the winter coat away just yet. New England’s spring is known for its unpredictability, and cold fronts can still bring sudden drops in temperature. While the second half of March will feel more like spring, a surprise snow shower or chilly morning frost can’t be ruled out.
How to Stay Prepared for March’s Weather Swings
- Stay Informed – Weather conditions can change quickly, so check forecasts regularly to stay ahead of sudden storms.
- Prepare for Snow and Rain – Shovels, rain boots, and umbrellas will all be necessary at different points this month.
- Watch for Flooding – Rapid snowmelt combined with heavy rain could lead to minor flooding in some areas. Be cautious near rivers and streams.
- Dress in Layers – Temperatures will fluctuate from freezing in the morning to mild in the afternoon, so dressing in layers is the best way to stay comfortable.
March in New Hampshire is a month of transition, balancing between the last gasps of winter and the first real signs of spring. With snow, rain, and fluctuating temperatures, the weather will keep residents on their toes. Stay prepared, stay informed, and be ready for whatever Mother Nature throws your way!
