A stalled frontal boundary just north of Florida will allow deeper tropical moisture to move back into the area, increasing the coverage of afternoon showers and thunderstorms through the rest of the week and into the Fourth of July holiday weekend.
Wednesday's storms will develop as the Atlantic sea breeze pushes inland during the afternoon. The greatest coverage is expected across western Palm Beach County, the Lake Okeechobee region, and inland portions of Martin, St. Lucie and Indian River counties before some storms drift back toward the coast during the evening.
While rain chances increase, the heat isn't going anywhere. Afternoon highs will reach around 90 to 92 degrees, with heat index values climbing between 100 and 107 degrees. A Moderate to Major HeatRisk remains in place, meaning anyone spending extended time outdoors should stay hydrated, take frequent breaks in the shade or air conditioning, and limit strenuous activity during the hottest part of the day.
Looking ahead, scattered to numerous afternoon showers and thunderstorms are expected Thursday and Friday as tropical moisture continues to increase. That pattern is likely to continue into the Fourth of July weekend, with dry mornings giving way to scattered afternoon and evening storms typical of early July in South Florida.
