Manchester, N.H. – Dangerous summer heat will grip southern New Hampshire as highs climb toward 91 degrees in Manchester on Tuesday, July 15, with sunny skies and patchy fog lingering through the morning. Roads like I-293 and Route 3 could see reduced visibility before 9 a.m., while soaring midday temperatures prompt a heat safety alert across the region.
According to the National Weather Service, fog may slow down commuters early Tuesday, but by mid-morning, intense sunshine will dominate. Residents should limit outdoor activity, stay hydrated, and check on vulnerable neighbors and pets. The heat index is expected to make it feel even hotter, especially for those without air conditioning.
City infrastructure may be strained as demand for electricity spikes, and cooling centers could open if conditions worsen. The threat of heat-related illness remains high, so take frequent breaks and never leave children or pets in vehicles.
Looking ahead, the weather stays hot and mostly sunny through Wednesday, with highs reaching 93 degrees. Thursday brings a 50% chance of showers and thunderstorms, especially after 2 p.m., which could lead to slick roads and travel delays around Manchester and Bedford. Rain chances return Friday, paired with slightly cooler temperatures near 89 degrees.
This weekend, drier, sunnier weather moves in. Saturday and Sunday both feature highs in the low to mid-80s, perfect for outdoor plans, but always check the latest local updates as new advisories could be issued.
