Jacksonville is starting Wednesday mostly clear near 80°F, but the day is headed toward a 95-degree high and heat index near 106°F. A Heat Advisory runs from noon to 7 p.m., with thunderstorms likely after 1 p.m. and a chance of strong wind gusts. The safest window for outdoor plans is the morning, before the heat and storm threat stack up.
Heat Peaks Before Storms Roll In
The National Weather Service in Jacksonville expects mostly sunny skies through late morning, with west winds around 6 to 10 mph and temperatures rising into the low 90s by early afternoon. The advisory covers parts of northeast and northern Florida and southeast Georgia, where heat-index values could reach 110°F, according to the National Weather Service Jacksonville.
Storm chances increase after 1 p.m., reaching their best odds during the mid-to-late afternoon, with a 60% chance overall and new rainfall totals between a tenth and a quarter of an inch. Some storms could produce very heavy rain and 40-60 mph wind gusts, so outdoor workers and drivers should be ready for a quick change in conditions.
Warm Nights And Near-Record Heat Ahead
Tonight brings a 50% chance of showers and thunderstorms before 10 p.m., followed by mostly cloudy skies and a low near 78°F. Thursday and Friday look even hotter, with highs near 97°F and heat indexes up to 107°F, while Saturday stays near 97°F under mostly sunny skies.
Scattered afternoon storms remain possible through early next week, including Sunday and Monday, even as highs hover in the mid to upper 90s. The National Weather Service says near-record highs are possible Thursday through Saturday, making this a hotter sequel to an earlier Jacksonville weather update.
How To Handle The Advisory
Drink plenty of fluids, stay in an air-conditioned room when possible, avoid direct sun and check on relatives and neighbors during the advisory. If you must be outside, limit strenuous activity and plan it for the morning or evening, when conditions should be less punishing.
