Sea breezes will help trigger scattered showers and thunderstorms beginning early to mid-afternoon, with the greatest coverage developing inland before some storms drift back toward the coast during the late afternoon and evening.
A few storms could produce frequent lightning, torrential downpours, and gusty winds, leading to brief localized street flooding.
Rain chances are around 50 to 60 percent across the Palm Beaches and Treasure Coast. Storms gradually diminish after sunset, just in time for the fireworks displays.
Beach and boating conditions remain generally favorable this weekend with light southeast winds around 5 to 10 mph. However, keep an eye on the sky as thunderstorms can develop quickly and produce dangerous cloud-to-ground lightning and locally rough conditions on the water.
Sunday will heat up in the morning under a partly sunny sky. Storms will become more likely in the afternoon as the sea breeze develops. Regardless, it will be hot and humid with highs in the lower 90s and feels-like temperatures topping 100 degrees.
Have a safe and fun Fourth of July weekend!
