TODAY: A soggy, unsettled Sunday is in store. Expect showers and likely thunderstorms by late morning and afternoon, some capable of gusty winds and heavy rainfall. High in the lower 80s. Rain chance: 70%.

TONIGHT: Partly cloudy with showers likely in the late evening and early morning hours. Another round of storms is possible. Low in the upper 60s. South winds five to 10 mph, gusts to 20 mph. Rain chance: 60%.

THIS WEEK: Monday brings more of the same. Showers return in the late afternoon with an 80% rain chance and highs in the mid-80s. This is the wettest day of the stretch. The pattern then shifts dramatically: a cold front pushes through Monday night, winds swinging west then northwest, with lows dropping to the upper 50s. By Tuesday, skies remain mostly cloudy but rain chances collapse to just 20%, and highs tumble to the mid-60s. That is a 20-degree drop from Monday. Plan outdoor projects accordingly.

ON THE WATER: South winds 10 to 15 mph with gusts to 25 mph Sunday afternoon make for a rough, choppy ride inshore and nearshore. Boaters should expect building seas. Monday conditions mirror Sunday before the front arrives. Tuesday's northwest wind shift at 10 to 15 mph, gusts to 25 mph, will produce a short, steep chop — not ideal for offshore runs. The best fishing window this weekend is early Sunday morning before storms fire up.

ALERTS: No active National Weather Service watches, warnings, or advisories are in effect for the Treasure Coast at this time. Monitor NWS Miami for updates as the front approaches Monday night.
