Manchester, N.H. – Drivers across southern New Hampshire may face a slow start to Labor Day as thick patchy fog develops overnight into Monday morning. Visibility could quickly drop on highways, including I-293 through Manchester, before conditions improve by late morning. Motorists should use caution, slow down, and allow extra time for early travel.
According to the National Weather Service, fog will linger until about 9 a.m. Monday, followed by clearing skies and highs near 79 degrees. Winds remain calm through the morning, easing concerns for power disruptions but making road visibility the greatest hazard.
Manchester, Concord, and Nashua will see the heaviest fog risk before sunshine breaks through for afternoon cookouts, parades, and outdoor events. Those driving before sunrise should keep headlights on low beam and be alert for sudden visibility changes along river valleys and secondary roads.
The rest of the week brings a stretch of mostly sunny and warm afternoons. By Wednesday, highs climb into the lower 80s before a late-week shift to wetter, cooler air. Showers are expected Thursday night into Friday, with a chance of heavier rain Friday afternoon.
Residents planning Labor Day celebrations outdoors can expect pleasant conditions after the morning fog burns off. Keep travel plans flexible, and check updates if leaving early in the morning.
Warnings for fog remain in place through 9 a.m. Monday, with the next advisory update expected overnight.
