Saturday, September 5, starts clear and muggy around Orlando, with temperatures near 77 degrees and humidity already running high. Sunshine will push the city toward a high near 93, but the calm morning is expected to give way to showers and thunderstorms after 2 p.m. The heat index could reach 105 before storms cool things down.

The National Weather Service puts the afternoon rain chance at about 60%, with the best odds arriving from late afternoon into early evening. Winds should stay light from the west-southwest near 5 mph, though stronger storms could produce gusts of 35 to 45 mph, frequent lightning and sudden heavy rain.

Heavy Downpours Could Flood Low Spots

Slow-moving or repeated storms may drop 2 to 4 inches of rain in a short period, creating ponding and minor flooding in low-lying or poorly drained areas. Drivers could also run into sharp visibility drops and slick roads during the afternoon storm window. No watches, warnings or advisories are listed for the Orlando area.

Tonight brings a 50% chance of showers and thunderstorms before 8 p.m., followed by partly cloudy skies and a low near 76. The storm pattern covered in Friday's Hoodline forecast is now carrying a clearer heavy-rain concern into the holiday weekend.

Labor Day Looks Like The Wettest Holiday Window

Sunday will again reach about 93 degrees, with a 50% chance of afternoon showers and thunderstorms and a heat index near 103. Labor Day Monday looks stormier, with showers possible in the morning before thunderstorms become more widespread and an 80% rain chance develops.

The unsettled pattern continues Tuesday and Wednesday, when highs should stay near 91 degrees and daily thunderstorm chances reach 70%. Thursday remains mostly sunny before storms return, while Friday brings another hot afternoon near 92 with a 50% chance of rain.

Plan Outdoor Time Around The Storms

Morning errands and outdoor plans have the best odds of staying dry, but conditions can change quickly after lunch. Anyone who hears thunder should move indoors, and residents should avoid driving through flooded roadways even if the water looks shallow.
