“The areas with the hottest temperatures will be across the Panhandle, where high temperatures will be 3 to 6 degrees above historical average through the week.

“Across southern Florida, high temperatures will be 2 to 4 degrees above historical averages.
“Overall, AccuWeather RealFeel Temperatures will be between 100 to 110 degrees this week across the state, with the highest values in the Panhandle.
“There can also be periodic thunderstorms throughout the week that can offer some relief from the heat but can bring heavy downpours and localized damaging winds.
“Temperatures are expected to slightly drop on Saturday (July 4) and Sunday, but will still be near or slightly above historical averages.”
