Manchester, New Hampshire – Cooler mornings and pockets of patchy fog could slow commutes across southern New Hampshire early Monday, with the most impact near Manchester and along I-293 before 8 a.m. Visibility may drop quickly before sunrise, especially in low-lying areas and near rivers.
According to the National Weather Service in Gray, Maine, fog will be the main hazard heading into Monday morning, with calm winds and overnight lows around 51°F. By midday, skies will clear, and Manchester is expected to reach a high near 78°F with light east winds—typical of the early fall transition. Drivers are urged to reduce speed and use headlights when traveling through fog-prone stretches.
The rest of the week offers a stretch of mild, sunny weather, with temperatures gradually climbing into the low 80s by midweek. Tuesday and Wednesday will be mostly clear, with crisp mornings and warm afternoons. The calm pattern continues through Friday, giving residents a perfect window for fall outdoor plans.
While no watches or warnings are currently in effect, forecasters note that the early morning fog could return Tuesday. Those with early commutes should prepare for variable visibility before sunrise each day this week.
