Manchester, N.H. – Widespread haze and surging heat will grip New Hampshire starting Wednesday, with highs near 89°F and visibility concerns for drivers. Air quality may deteriorate during peak commuting hours, especially along Route 3 and I-93, as stagnant conditions settle in.
According to the National Weather Service, Wednesday will bring dense haze and sunshine with light southwesterly winds increasing to 10 mph by late afternoon. By Thursday, the heat intensifies — temperatures could climb to 92°F in Manchester, Nashua, and Concord. A 30% chance of late-day showers may offer brief relief, but the bigger concern arrives Friday.
Friday night could bring a more significant threat: thunderstorms are expected to move in after 2 a.m. with a 60% chance of precipitation. These storms may impact early Saturday travel plans and outdoor events across Hillsborough and Rockingham counties.
Motorists should use headlights during hazy morning hours and remain alert for rapidly changing visibility. Stay hydrated, avoid strenuous outdoor activity during peak afternoon heat, and check air quality indexes before outdoor exercise.
The threat of strong storms continues into Saturday, with showers likely and highs around 74°F. Sunday offers a slight chance of more rain, but temps cool slightly into the low 70s.
