Orlando is starting Wednesday clear and already warm, with temperatures around 82 degrees early in the morning. The bigger story arrives by late morning: a Heat Advisory runs from 10 a.m. to 8 p.m., with the heat index expected to reach 108 to 112 degrees and the afternoon high near 96. Skies should stay mostly sunny for much of the day, but the heat will not be the only thing demanding attention.
Storms May Crash The Evening
According to the National Weather Service, a 20% chance of showers and thunderstorms develops after 5 p.m., with isolated storms potentially bringing frequent lightning, sudden 30- to 50-mph wind gusts and pockets of heavy rain. Most activity should fade around 8 p.m., though a slight chance remains before 10 p.m. Tonight will turn mostly clear, with a low near 77.
Heat Wave Keeps Orlando Sweltering
Thursday looks much the same: mostly sunny, a high near 96, heat index up to 107, and a small storm chance after 4 p.m. Friday could be the hottest day, reaching 97 with a 40% chance of afternoon and evening storms; heat index values are expected to remain near advisory levels. The broader pattern stays hot through next Tuesday, with highs around 95 to 96 and daily storm chances generally ranging from 30% to 40%.
Saturday Offers A Brief Dry Break
Saturday is the outlier, with sunny skies, a high near 95 and only a 10% rain chance. That break looks temporary, as scattered afternoon storms return Sunday and continue into Monday and Tuesday. Winds stay generally light, shifting from west to south-southeast as the sea breeze develops.
Plan Around The Heat
The most punishing window will be roughly 10 a.m. to 4 p.m., when outdoor work and exercise should be moved earlier or later if possible. Drink plenty of fluids, take frequent breaks in shade or air conditioning, and wear lightweight, loose-fitting clothing; children and pets should never be left in a parked car.
Orlando's extreme-heat guidance also urges residents to watch for signs of heat sickness and use indoor options on dangerously hot days. Anyone showing signs of heat stroke should be moved to a cool place and 911 should be called.
