Huntsville, Alabama – Thunderstorms could disrupt outdoor plans across the Tennessee Valley Friday and Saturday, but a much more dangerous threat will follow — heat indices soaring near triple digits through early next week.
According to the National Weather Service in Huntsville, scattered showers and storms will linger through Saturday evening, with rain chances ranging from 20–40% Friday and 10–20% Saturday. Despite the clouds, daytime highs will still hit the low to mid-90s, with oppressive humidity holding overnight lows in the 70s.
By Sunday, a drier and hotter air mass takes hold. High temperatures will steadily rise from 96°F Sunday to near 98°F by Monday and Tuesday. Heat index values could exceed 100°F in several areas, especially in urban zones like Decatur, Florence, and Scottsboro.
Residents are urged to limit time outdoors during peak heat, hydrate frequently, and check on vulnerable individuals — particularly children, seniors, and pets. With schools returning and weekend travel picking up, heat-related illnesses may become more common if precautions aren’t taken.
This stretch of intense summer heat is expected to persist through at least Tuesday, with additional heat advisories possible if conditions worsen.
