MANCHESTER, N.H. – Gray skies and thick morning fog are setting the tone across southern New Hampshire as a strong fall storm system takes aim for Monday. The calm Sunday morning near 42°F will give way to increasing clouds through the day before rain spreads in by daybreak Monday, bringing slick roads, reduced visibility, and blustery winds to start the workweek.
According to the National Weather Service in Gray, Maine, steady rain will arrive early Monday, intensifying through midday with isolated thunderstorms possible between 7 a.m. and 1 p.m. Southeast winds could gust up to 30 mph, especially along I-93 and Route 101, making the commute slow and slippery. Rainfall amounts may reach three-quarters of an inch, with brief ponding likely in low-lying or urban areas. Power flickers are possible where wind and wet leaves combine on lines.
The front exits quickly Monday night, leaving behind cooler, calmer air and patchy clouds. Tuesday will feel like a different season — drier, breezier, and comfortable near 65°F under full sunshine. Midweek brings another weak front, with scattered showers expected Wednesday and a crisp, bright finish Thursday.
Residents planning leaf cleanup or Halloween decorating should target Tuesday or Thursday for outdoor work. Early signs of a “cold snap” pattern appear late in the week, when nighttime lows could flirt with the upper 30s — a reminder that New England’s early-winter transition is quietly underway.
