Jacksonville, Florida – Dangerous heat and summer thunderstorms will return to Jacksonville on Friday, August 1st, threatening to disrupt afternoon commutes and outdoor plans along major roads like I-95 and I-10. Residents should be ready for a sweltering day, as the National Weather Service predicts a high near 97°F, with heat index values soaring as high as 107°F before storms move in by late afternoon.
According to the National Weather Service, there’s a 30 percent chance of showers and thunderstorms after 2 p.m. Friday, with the greatest risk coming during peak travel hours. Strong winds and heavy rain could lead to slick spots and minor flooding on key routes, including I-95, I-10, and local Jacksonville streets. Motorists are urged to monitor real-time alerts, avoid flooded areas, and slow down when storms strike. Heat safety remains critical—hydrate frequently and take breaks if working outdoors.
By Friday night, scattered storms may linger, giving way to more widespread thunderstorm activity Saturday. Storm chances jump to 80% on Saturday, with rain likely to last into Sunday and even through early next week. Outdoor events, youth sports, and travel plans could face interruptions across Duval, Clay, and St. Johns counties.
These stormy conditions mark a classic August start for northeast Florida, where muggy air and daily thunderstorm threats are the norm. Power outages and minor tree damage are possible—charge devices in advance and have a plan for indoor activities.
