Manchester, N.H. – Thunderstorms and sizzling heat will grip much of New Hampshire this Thursday, July 17TH, with Manchester residents bracing for scattered storms, steamy humidity, and a high near 90°F. Commuters on I-293 and Route 101 should be ready for sudden downpours and hazardous road conditions, especially late morning through the afternoon. Temperatures will feel as high as 99°F, turning routine errands into a test of endurance.
According to the National Weather Service, showers and thunderstorms are most likely after 9 a.m. Thursday, with a 40% chance of rain and the risk of localized flooding. Southwesterly winds of 5 to 10 mph may bring brief relief, but muggy air will persist. Residents are urged to limit outdoor activity, stay hydrated, and check on vulnerable neighbors. Keep cellphones charged in case of storm-related outages and avoid parking under trees during gusty storms.
Manchester’s summer heat will ease a bit by Friday, with mostly sunny skies and a high near 82°F. By Saturday, highs will hover in the mid-80s under mostly sunny skies—ideal for outdoor plans, but stay weather-aware as the next round of showers is possible late Saturday night into Sunday. The region’s pattern of hot, humid afternoons and evening storms could linger into early next week, making it important to check daily forecasts and adjust plans as needed.
Warnings and advisories will remain in effect as storms move through Thursday. Watch for future updates if conditions change or additional alerts are issued.
