Rain is likely this afternoon as deep tropical moisture moves through the region, and the best chance for it comes between 2 p.m. and 7 p.m. Most spots can expect rain and a few thunderstorms, with the strongest cells capable of heavy rain, lightning and brief gusty winds.
That matters now because the wet window lands squarely in the middle of the day and rolls into the evening, when travel and outdoor plans are hardest to adjust. Extreme downpours could create trouble on routes between FL-20 and U.S. 84, including I-10 travel this evening, while highs in the upper 80s to low 90s will quickly fall into the low to mid 80s once showers move through.
The holiday weekend keeps the pattern unsettled. Rain coverage looks a little lower for Saturday, with the best chance in the Big Bend of Florida, mainly south of I-10 and near I-75, and temperatures again reaching the low 90s. By Sunday, coverage turns greater as a cold front approaches the Northern Gulf Coast, setting off showers and storms north along Highway 82 before they move south through the afternoon and evening.
That is where the forecast gets less clean. Saturday looks a bit drier, but the front arriving Sunday raises rain coverage again and brings back the risk of stronger storms, especially when the sea breeze gets going along Highway 98 in Florida and clashes with the boundary. Gusty winds are expected to be the main threat, and a few severe thunderstorm warnings are possible, even as Sunday stays hot and humid with highs in the low to mid 90s.
The pattern does not shut off after the weekend. Sunday’s front is expected to stall just south of the area on Monday, keeping the weather unsettled with partly to mostly cloudy skies and occasional showers and storms. Tuesday and possibly Wednesday still carry a decent chance for rain, with slightly drier air possibly returning late in the week. For people watching Miami weather, the simplest answer is that the wet stretch is not a one-off afternoon burst; it is a run of showers and storms that keeps going through Labor Day Weekend.
