Jacksonville, Fla. – Jacksonville’s summer is about to turn up the heat and unleash scattered thunderstorms just as midweek routines hit full stride. Temperatures will climb to 91°F on Wednesday, July 16th, with afternoon storms bringing the risk of street flooding and dangerous lightning across Duval County. Expect sticky humidity and gusty winds—drivers on I-295 and surface roads should plan for wet pavement and sudden slowdowns after lunchtime.
According to the National Weather Service, storms may develop by noon, with the most active weather stretching into Wednesday evening. South winds will reach 10 to 15 mph, and rainfall totals could reach a half inch in spots. Isolated strong storms could bring locally heavy downpours and wind gusts up to 23 mph. If you have to travel, allow extra time, avoid flooded areas, and charge your devices now to prepare for possible power outages.
Showers linger into Wednesday night, keeping roads slick and visibility low. By Thursday, skies clear early before another round of thunderstorms fires up by the afternoon, along with highs near 92°F and summer heat index values topping 100°F. Friday brings a mix of sun and storms, with temperatures peaking near 93°F—perfect fuel for another round of afternoon showers.
