Heat, Heavy Rain and Thunder to Hammer Treasure Coast Through Midweek

TODAY: The workweek opens with a punch. Expect considerable cloud cover and a 60% chance of rain Monday, with showers arriving late morning and becoming likely by late afternoon and near sunset. Highs climb into the lower 90s — brutal enough on their own, but a heat index surging to 104°F makes this a dangerous combination for anyone working or playing outside, the National Weather Service said. Southeast winds will run five to 10 mph.

TONIGHT: Clouds linger overnight with a 40% chance of showers and thunderstorms pushing through the late evening and early morning hours. Low temperatures settle into the mid 70s with southwest winds around five mph.

THIS WEEK: There is no drying out in sight. Tuesday brings a 70% rain chance — the highest of the stretch — with showers likely and thunderstorms possible, highs dropping to the mid 80s as winds shift northeast late in the day. Tuesday night holds another 70% chance of rain through the overnight. Wednesday mirrors Tuesday almost exactly: considerable clouds, a 70% rain probability, showers likely again by late afternoon, and highs again in the mid 80s with east winds five to 10 mph. This sustained mid-May soaking runs ahead of the official June 1 rainy season start but fits the pattern of early-onset convective activity that forecasters observed in May 2024 as well — a reminder that the Treasure Coast's wet season rarely waits for the calendar.

ON THE WATER: Southeast winds at five to 10 mph Monday morning offer a manageable early window for nearshore anglers before afternoon storms shut things down hard. The incoming storm energy will stack baitfish tight to structure — try pilchards or threadfin herring along the St. Lucie Inlet's south jetty during the first two hours of incoming tide before midday. Once that heat index climbs past 100°F and anvil clouds build to the west, get off the water. Tuesday and Wednesday's persistent northeast wind shift will push rougher, choppier conditions inshore, making both days poor bets for anyone without a pressing reason to go out.

ALERTS: No active NWS watches, warnings, or advisories are in effect for Martin, St. Lucie, or Indian River counties at time of publication. Conditions capable of producing lightning remain elevated through Wednesday — treat every afternoon storm cell as a lightning threat.
