Manchester, New Hampshire – Summer heat builds across southern New Hampshire on Tuesday, June 3rd, as sun-drenched skies push temperatures near 80°F in Manchester and across the Merrimack Valley. Commuters along I-293 and I-93 can expect dry pavement and clear skies, but the heat will linger through midweek before thunderstorm chances return Thursday.
According to the National Weather Service in Gray, Maine, Tuesday will bring calm winds and strong sunshine, with daytime highs around 80°F across Hillsborough County. Tuesday night remains mostly clear with lows near 52°F—ideal conditions for evening walks, grilling, or open-window sleeping.
Wednesday turns even hotter, with highs soaring to 88°F. Thursday marks a major shift: a 30–40% chance of afternoon thunderstorms may arrive after 2 p.m., with temperatures peaking around 91°F.
