Huntsville, Alabama – Dangerous heat and daily afternoon thunderstorms are expected to impact North Alabama through Saturday, with heat index values in Huntsville climbing as high as 108° by midweek.
According to the National Weather Service in Huntsville, high temperatures between 88° and 95° will combine with humidity to produce dangerous heat index readings ranging from 99° to 108° through Saturday. Thunderstorm chances will increase midweek, peaking at 60% Friday and Saturday.
Residents across Madison, Limestone, and Morgan counties should be alert for heat-related illnesses, particularly during afternoon hours. Light clothing, hydration, and limiting time outdoors—especially between 12 and 5 p.m.—are strongly recommended. The NWS also reminds drivers to never leave children or pets inside parked vehicles, even briefly.
Afternoon storms could bring frequent lightning, gusty winds, and brief downpours, especially Thursday through Saturday. The combination of heat and pop-up storms could lead to delays on I-565, US-72, and other major routes during evening commutes.
