Miami starts Friday with scattered to isolated showers, mainly during the morning, and temperatures near 81 degrees, but the calm will not last all weekend. The city is headed for a high around 88, a heat index near 103, and a growing chance of showers and thunderstorms as the day wears on.
Friday Stays Hot Before Storm Chances Rise
Rain chances remain limited for Miami through much of Friday, with southeasterly winds around 10 knots and mostly sunny to partly sunny conditions. Most of the day's storms are expected inland and across Southwest Florida, but Southeast Florida could still see isolated showers, especially during the morning.
Friday night turns more unsettled, with a 30% chance of showers and thunderstorms and a low near 79. The latest forecast is a sharper turn than Hoodline's earlier outlook, which had already flagged a stormier weekend.
Saturday Looks Like The Weekend's Messiest Day
Saturday brings the biggest weather shift, with an 80% chance of showers and thunderstorms and highs in the low to mid-80s for most areas. Rain chances climb through the day, and Saturday night stays wet with an 80% chance of storms and a low around 77.
The National Weather Service Miami says heavy rain could create flooding concerns Saturday, particularly if downpours stall over the same neighborhoods. Its forecast discussion identifies rainfall scenarios of 3 to 6 inches across parts of Southeast Florida, so outdoor plans should have an indoor backup and drivers should watch for ponding on roads.
Winds Turn Up Sunday
Sunday remains unsettled, with a 90% chance of precipitation, a high near 83, and northeast winds between 21 and 24 mph. Gusts of 20 to 30 mph are possible over several days, while Sunday night brings another 80% chance of precipitation and gusts up to 26 mph.
Boaters should expect conditions to deteriorate as winds shift north to northeast and seas rise from roughly 2 to 3 feet Friday to 7 to 10 feet or higher over the weekend. The stronger wind pattern may continue into next week, with highs in the low to mid-80s, overnight lows in the low to mid-70s, and periodic rain chances still in the forecast.
