Miami rolled into Saturday, May 30, under a warm, sticky blanket of air, clear at the airport with early temperatures around 79°F and dew points in the mid 70s. Most of the day should stay mostly cloudy with a high near 86°F and light southwest winds. A few showers and thunderstorms could pop late this afternoon, but coverage is expected to stay limited. No watches or warnings are in effect this morning.
Afternoon Storm Threat
With a mid level cloud deck trying to cap the atmosphere, any storms that manage to get going will likely fire along the Atlantic seabreeze, mainly from northern Broward into Palm Beach County. Saturday afternoon carries about a 30% chance of showers and thunderstorms after 2 p.m., with most spots picking up between a tenth and a quarter of an inch of rain where storms do form and brief heavy downpours possible. Much of Miami should stay dry, but late day drives could feature slick roads and short delays, so it is smart to allow extra commute time if you will be on the road. According to the National Weather Service, storm coverage should remain limited today.
Sunday Heat And Safety
Rain chances tick up on Sunday, May 31, with showers and thunderstorms likely after 1 p.m. and highs pushing near 88°F. Heat index readings could sneak past 100°F in a few spots. The forecast discussion highlights an elevated heat illness risk from Sunday into early next week, so shift strenuous outdoor plans to the morning hours and drink water often. If you need a break from the humidity, Miami Dade lists county cooling sites and libraries that open during heat season, and residents are advised to check the county’s list for locations and hours.
Boaters And Commute
Out on the water, marine conditions look calm through the weekend with gentle westerly winds and low seas. A northerly swell may nudge seas higher near the Gulf Stream early next week. There are no marine or heat watches posted right now, but forecasters are calling for multiple rounds of showers and thunderstorms into midweek. For boating or beach plans, keep an eye on the sky for sudden storms and brief heavy rain, which can quickly cut visibility and trigger localized coastal flooding in low lying areas.
Quick Tips
Plan for muggy mornings and isolated afternoon storms, and keep water, sunscreen, and a light rain jacket handy for late day outings. Anyone with outdoor work or weekend events should monitor forecast updates, as conditions are expected to trend toward more widespread storms early next week.
