Miami is starting Wednesday clear, calm and already muggy, with temperatures around 79 degrees before sunrise. The quiet opening will give way to another round of afternoon showers and thunderstorms, with heat pushing the feels-like temperature as high as 106 degrees.

Mostly sunny skies should hold through early afternoon, but the storm chance rises after 2 p.m. Wednesday, according to the National Weather Service. Miami is expected to reach about 89 degrees, with southeast winds between 3 and 8 mph and a 50% chance of rain.

Slow-Moving Storms Could Bring Flooding

Storms may carry frequent lightning, gusty winds and brief heavy downpours. Because the storms could move slowly or stall, localized flooding is possible, especially in urban neighborhoods and areas with poor drainage.

Wednesday night stays warm and humid, with a low near 82 degrees and another 50% chance of showers and thunderstorms before 11 p.m. Thursday looks much the same: mostly sunny at times, a high near 89, and a 50% chance of storms beginning after 8 a.m.

Wet Pattern Takes Over The Weekend

The forecast turns substantially wetter from Friday through Labor Day. Rain and thunderstorm chances reach 70% Friday through Sunday, then rise to 80% on Monday, with daytime highs remaining near 88 to 89 degrees and overnight lows mostly in the low 80s.

Friday could be especially disruptive for outdoor plans, with showers and thunderstorms likely for much of the day and evening. Saturday and Sunday also bring frequent storm chances, so keep lightning shelter and sudden downpours in mind before heading to the beach, parks or weekend events.

No Watches Or Warnings Posted

No watches, warnings or advisories are listed for the Miami area in the supplied forecast. Anyone caught outside during a storm should move indoors, avoid flooded roads and wait until thunder has stopped before resuming outdoor activities.
