JACKSONVILLE, Fla. – Showers and storms continued to move across Northeast Florida and Southeast Georgia Tuesday morning.

If things have felt extra warm lately, it’s not your imagination.

Summer doesn’t officially arrive until later this month, but it already feels like summer across Jacksonville.

Recent mornings have been hot and very humid, with early temperatures in the mid-70s to low 80s, especially around the coast. Mayport, for example, tends to be the warmest spot in the early mornings.

The latest forecast from The Weather Authority and Exact Track 4D expects highs to reach 92 degrees today and again tomorrow, with heat index values making it feel even hotter—potentially as high as the triple digits during the peak afternoon hours.

Even after sunset, things don’t cool down much: tonight’s low is only expected to drop to 73 degrees.

Pop-up showers and thunderstorms

While the heat remains the big headline, News4JAX viewers should be ready for changing skies.

Our team is tracking a line of showers and storms rolling in from the west, currently located near Tallahassee and Thomasville, Georgia.

While those storms are outside our viewing area early on, they’re expected to push into the Jacksonville region later in the morning.

Best estimate on timing? Look for increased rain chances between about 10:45 a.m. and 11 a.m., stretching through lunch and into the early afternoon.

The Exact Track 4D radar suggests a 40% to 50% chance of rain for Jacksonville, so many could stay dry, but others will contend with scattered showers and the possibility of isolated strong storms—especially in areas highlighted as higher risk on the severe weather maps shared by The Weather Authority.

In terms of rainfall totals over the next five days, Green Cove Springs could see nearly 2 inches, with Macclenny and Waycross looking at around 1.5 inches.

Jacksonville’s projection sits at about 1 inch, while the coast should expect less than a tenth of an inch.

This wet pattern is expected to linger through the weekend, according to The Weather Authority.

Beach and weekend weather

Planning a beach day? We’re forecasting air temperatures around 90 degrees and water temps at 83 degrees, making for classic Northeast Florida summer conditions.

But don’t let the breeze fool you—the UV index is high, so be sure to apply plenty of sunscreen.

The risk for rip currents is expected to be low to moderate, providing some peace of mind for those heading into the surf.

Still, always check local conditions before swimming.

For those out walking the dog, the prime time is early—temperatures are likely to climb quickly from the low 70s into the 80s by midday.

Looking ahead to the weekend, The Weather Authority is predicting a 60% chance of showers and storms on both Saturday and Sunday, with daytime highs in the low 90s.

That means it’s a good idea to plan for some wet weather alongside the heat.
