Jacksonville started Thursday, June 11, on a muggy note, with mostly clear skies, temperatures around 75°F and a dew point in the low 70s. Forecasters expect highs near 90°F this afternoon, along with a slight chance of showers and thunderstorms between 2 p.m. and 4 p.m. Southeast winds will pick up later in the day, with gusts into the low 20s. Beachgoers and afternoon commuters should be ready for quick downpours and sticky air ahead of an even hotter weekend.
Afternoon Showers Possible
Scattered storms are expected to favor inland areas this afternoon and into the evening, and any storm that pops up could bring heavy downpours and frequent lightning, especially near the I-75 corridor. Winds are forecast out of the southeast at 5 to 15 mph, with gusts to about 23 mph this afternoon. According to the National Weather Service in Jacksonville, overall coverage should stay limited, but brief bursts of heavy rain could quickly cut visibility on area roads.
Stay Cool Resources
If the heat or humidity becomes too much, the City of Jacksonville's Stay Cool Jax program lists cooling-center locations and free-ride rules on heat-emergency days. Libraries, community centers and public pools are available as daytime cooling options, and on Sundays the Main Library and the Legends Center serve as standby sites. These spots could be especially useful if heat-index values creep toward advisory levels later this weekend.
Weekend Outlook
Heat will ramp up Friday into the weekend, with highs climbing into the mid to upper 90s and heat-index values expected to reach roughly 105 to 110°F on Saturday and Sunday. Afternoon and evening thunderstorm coverage is expected to increase over the next few days, with locally heavy rain and gusty winds possible along and near I-95. The National Weather Service in Jacksonville advises limiting strenuous outdoor work during the hottest part of the day and keeping an eye on forecasts for possible heat advisories.
What To Do Today
Stay hydrated, take frequent breaks in shaded or air-conditioned spaces and, if possible, shift outdoor plans to the morning hours. If you are heading to the beach, expect onshore breezes and a moderate rip-current risk this afternoon. Always swim near a lifeguard and follow the posted flag warnings at area beaches.
