Manchester, NH – Southern New Hampshire is bracing for a dual threat this Juneteenth. A surge of extreme heat combined with a line of potentially severe thunderstorms will create challenging conditions, especially on Thursday afternoon and evening.
Juneteenth Forecast
Thursday will bring dangerously high temperatures, with the heat index in Manchester expected to reach 96°F. This intense heat, along with high humidity, will make it feel much hotter than the actual temperature, posing a health risk, especially for vulnerable groups. Along with the oppressive heat, severe thunderstorms are expected to develop in the afternoon and continue into the evening. These storms could bring damaging winds, hail, and torrential downpours, increasing the risk of flash flooding. The combination of heat and storms could cause travel disruptions, particularly along major roads like Interstate 93 and the Everett Turnpike. Residents should stay hydrated and avoid prolonged exposure to the sun during the hottest parts of the day, while also securing loose outdoor items that could be blown away by strong winds. Power outages may occur, so it’s important to ensure mobile devices are fully charged.
Friday and Weekend Outlook
The stormy conditions will clear out by Friday morning, leaving behind a calmer and much more pleasant day. Friday’s forecast calls for mostly sunny skies and a high near 81°F, offering a brief relief from the heat. Saturday will be warmer with mostly sunny conditions and a high near 86°F. Sunday will continue the trend, with mostly sunny skies and temperatures climbing to around 89°F.
