Jacksonville woke up Wednesday, May 6, to a pretty tame start: partly cloudy skies and upper 60s. That calm will not last long. Forecasters expect a fast warm-up to around 93°F this afternoon, with light south winds of 5 to 10 mph helping crank up the heat. By Thursday, inland areas are expected to bake in the mid to upper 90s as the hot pattern intensifies.
Heat Spike Thursday
On Thursday, May 7, highs are forecast to climb into the mid 90s, with some inland spots potentially pushing into the upper 90s and heat-index values near or topping 100°F in urban corridors. Coastal neighborhoods should run a few degrees cooler, but it will still be warm enough to make outdoor jobs and afternoon practices feel rough. Officials recommend extra water breaks and shifting strenuous activity to the morning or evening, according to the National Weather Service in Jacksonville.
Fire Weather Watch Thursday Afternoon
At the same time the heat ramps up, the National Weather Service has issued a Fire Weather Watch for Thursday afternoon into the early evening for inland and north-central parts of northeast Florida. Forecasters warn that southwesterly winds of 15 to 20 mph, gusting up to 30 mph, combined with relative humidity dropping into the upper 20s, could let new or existing fires spread quickly. A Fire Weather Watch means critical fire-weather conditions are possible, so residents are urged to avoid outdoor burning and to use extra caution with grills and power equipment, according to a Fire Weather Watch from the National Weather Service in Jacksonville.
Storm Timing And Marine Concerns
A cold front will move in late Thursday and then stall near the I‑10 corridor, setting up scattered showers and thunderstorms from Friday through Monday, with the best shot at heavier rain across southeast Georgia. There is also an increasing threat of strong to isolated severe storms over the weekend, especially Sunday evening, so organizers of outdoor events should have backup plans ready. Along the coast, forecasters note a moderate rip current risk today that is expected to ease to a lower risk on Thursday, while boaters should plan for choppy seas and gusty onshore winds.
If you are heading outside this afternoon or Thursday, try to schedule the hardest work for the cooler hours, keep water close, and secure loose items ahead of gusty winds. Skip open burning while the watch is in place and check local rules if you use a backyard fire pit or run outdoor power tools. Stay tuned to updated forecasts and any Red Flag Warnings that may follow as conditions change.
