MANCHESTER, N.H. – After a frosty and calm start to the weekend, southern New Hampshire will see milder air and increasing rain chances by Monday. Early risers across the Merrimack Valley may still find frost on lawns and windshields this morning, but warmer, wetter air will soon replace the chill.
According to the National Weather Service in Gray, Maine, a weak front will push into southern New Hampshire late Sunday, bringing a round of showers and breezy conditions. Rain is likely to begin Sunday night and continue through Monday morning, with gusts near 25 mph possible along I-93 and Route 101. Temperatures will climb into the mid-60s Monday before cooling slightly midweek.
Residents should cover or bring in any sensitive plants that survived the recent frost and secure Halloween decorations before winds increase. Patchy fog may also reduce visibility Sunday morning, especially in low-lying valleys and near the Merrimack River. Drivers are urged to use low beams and allow extra space on slick roads.
Conditions improve Monday night as skies partially clear, setting up a stretch of classic fall weather. Sunshine returns Tuesday and Wednesday with highs in the 60s and cool, crisp mornings—ideal for leaf-peeping, hiking, and pumpkin patch visits.
By midweek, another system could bring scattered showers, but no severe weather is expected. The region’s first widespread frost of the season has passed, but cool nights will keep autumn’s chill firmly in place.
