Jacksonville, FL – Thursday afternoon storms could bring heavy rain, gusty winds, and dangerous heat to Northeast Florida, with conditions peaking between 2 p.m. and 8 p.m. The National Weather Service warns heat index values could climb as high as 107°F before thunderstorms develop, posing risks for both heat-related illness and localized flooding.
According to the National Weather Service in Jacksonville, showers and thunderstorms are most likely after 2 p.m., with a 50% chance of precipitation. The most intense activity may occur along I-95 and in urban areas where pavement heat can intensify storms. Drivers should be alert for reduced visibility and slick roads, especially during the evening commute.
Thursday’s weather will remain hot and humid even outside of storms, making hydration and limiting outdoor exertion critical. Outdoor workers and event organizers should plan for shade breaks and lightning safety protocols.
