Huntsville, Alabama – Huntsville residents should brace for dangerous heat and pop-up thunderstorms through Thursday, as high humidity drives heat index values to 104°F and scattered storms threaten afternoon plans.
According to the National Weather Service in Huntsville, a 40 percent chance of thunderstorms is expected each afternoon through Thursday, with patchy fog possible in the early mornings. Temperatures will climb to the mid-90s, while calm winds will offer little relief from the oppressive humidity.
Madison County communities, including Harvest and Meridianville, can expect the worst heat in the late afternoon, when heat index values soar past 100°F. Isolated thunderstorms may bring brief downpours, gusty winds, and dangerous lightning between 1 p.m. and sunset. Evening hours will see temperatures remain in the 70s, with fog developing overnight and a continued chance of overnight storms.
Residents are urged to limit outdoor activities during peak heat, stay hydrated, and use air conditioning if possible. If thunder roars, move indoors to avoid lightning risk. Local roads may see water pooling after heavy downpours, especially on Highway 72 and secondary roads.
The pattern of steamy heat and stormy afternoons will continue into Thursday, before rain chances drop slightly on Friday. Additional advisories may be issued if the threat intensifies.
