Miami woke to mostly clear skies and temperatures around 82 degrees Wednesday morning, but the calm start will give way to dangerous heat. A Heat Advisory is in effect across South Florida from noon through 7 p.m., with heat index values expected to reach 105 to 110.
The National Weather Service says the combination of high temperatures and humidity could cause heat-related illness. Miami’s high is expected to reach about 90 degrees, while the heat index could climb as high as 106.
Afternoon Storms Bring Some Relief
Wednesday should stay sunny through the early afternoon, with temperatures rising into the upper 80s before showers and thunderstorms become more likely after 2 p.m. The chance of rain is 40%, with southeast winds increasing from a nearly calm start to around 9 mph.
Storm chances will continue into the evening, especially before 8 p.m., followed by partly cloudy skies and an overnight low near 82. The NWS Miami discussion says storms may develop along the sea breezes and move slowly across southern South Florida, meaning some neighborhoods could see a longer downpour while others stay dry.
Heat Remains The Main Story Through Next Week
Thursday brings another sunny start, a high near 90 and a 30% chance of afternoon thunderstorms. Friday looks sunnier and slightly hotter at around 91 degrees, while Saturday brings another 30% chance of showers and thunderstorms with a high near 90.
Sunday is forecast to be sunny with a high near 91, followed by more heat Monday and Tuesday, when highs may reach 92. Rain chances become more limited early next week, but the prolonged heat will remain the bigger concern.
How To Handle Wednesday’s Heat
Wear lightweight, loose-fitting clothing, drink plenty of water and move strenuous outdoor plans to early morning or evening. Anyone spending time outside should watch for signs of heat exhaustion or heat stroke and take breaks in air conditioning or shade.
