A dangerous heat wave will grip northern Alabama and southern Tennessee starting this weekend, with temperatures soaring into the low 90s and heat indices climbing into the triple digits. At the same time, strong thunderstorms are expected to bring gusty winds, lightning, and the risk of localized flooding across the Tennessee Valley on Thursday afternoon.
Severe Thunderstorms Thursday
Before the heat settles in, a line of storms is expected to sweep through the region on Thursday afternoon, with gusts reaching up to 50 mph and brief, heavy rainfall. Cities like Decatur, Florence, and Scottsboro should be prepared for the potential of power outages and travel disruptions due to these storms. The storms could also bring localized flooding in areas with poor drainage.
Heat Wave to Begin Saturday
Starting Saturday, heat indices will climb as high as 105°F, marking the beginning of the first significant heat wave of summer 2025. The hot weather will continue through at least Tuesday, with highs in the low to mid-90s. On Monday and Tuesday, the heat indices are expected to reach 101–102°F, making outdoor activities dangerous without proper precautions.
Heat-Related Illness Risks and Safety Tips
With the soaring temperatures, there is an increased risk of heat-related illnesses, especially for those who spend extended periods outdoors. Residents are urged to stay indoors during peak heat hours, typically between noon and 4 p.m., and to use air conditioning whenever possible. Staying hydrated is crucial, and if you need to be outside, try to limit activity to early morning or evening hours when the heat is less intense.
If you hear thunder, it’s important to move indoors immediately to avoid the risk of lightning strikes. As the heat wave sets in, additional advisories may be issued, and residents should stay informed about the changing conditions.
