Seasonably warm and muggy again tonight, but with higher heat index values possible Wednesday and Thursday (>100°F, particularly for the Upper Keys). Light winds will also favor cloud line formation chances on Tuesday (late-morning/early-afternoon hours typically) leading to possibility of waterspouts. If out on the water, steer clear of any waterspouts you see as they can pose a hazard to boats. The current drier pattern looks to last through the upcoming holiday weekend, with just a slight chance of rain each day and night.

TODAY... Mostly sunny with a slight chance of showers and thunderstorms. Highs in the upper 80s. South winds near 5 mph. Chance of rain 10 percent.

Today... SE-S light to gentle breezes. Seas: Bay/Gulfside ≤1 ft; Hawk Channel ~1 ft; FL Straits ~1 ft; SE Gulf ~1 ft. Bay/nearshore waters smooth to a light chop. Slight chance of showers & thunderstorms.
