Michelle McCormick said a heat advisory may be needed Saturday afternoon as heat index values are expected to climb above 100 degrees across portions of southeast Georgia and nearly all of northeast Florida. Inland areas can expect lows in the lower to mid-70s before the hottest stretch arrives.
The News4Jax Weather Authority team said Saturday afternoon temperatures are forecast to reach the lower to mid-90s inland and the lower 90s along the coastline. Coastal communities will hold a touch warmer in the mid-75s overnight.

McCormick said the combination of heat and humidity will push the afternoon feel-like temperature well above the air temperature. She said inland areas can expect low temperatures to settle in the lower to mid-70s, which leaves little relief before the daytime heat builds.
Even without the storms, the heat alone tells quite a story. The warm overnight lows mean the day starts from a higher baseline, then climbs into the lower to mid-90s inland and the lower 90s along the coastline by Saturday afternoon.
southeast Georgia and northeast Florida
The highest apparent heat risk is centered on portions of southeast Georgia and nearly all of northeast Florida, where heat index values are expected to exceed 100 degrees in the afternoon. People in those areas should plan around the hottest part of the day and expect conditions to feel hotter than the thermometer shows.
El Paso Weather: Heat advisory posted as highs reach 106 degrees Wednesday shows how quickly heat headlines can move from forecast to action when temperatures and humidity rise together. Here, the forecast stops short of saying an advisory has been issued, so the immediate concern is the afternoon window when the heat index crosses 100 degrees.
Florida in the afternoon
The article does not say whether any official heat advisory will be issued for the affected areas. For now, the forecast gives readers the clearest practical cutoff: the hottest conditions are expected Saturday afternoon, after a warmer-than-normal night and before the evening eases the load.
That leaves the next step with readers and local forecasters alike: watch the afternoon forecast closely, because the difference between a hot day and a dangerous-feeling day here is the humidity pushing the heat index past 100 degrees.
