WEST PALM BEACH, Fla. (WFLX) - South Florida is in for another stretch of steamy weather through midweek, with afternoon heat indices climbing into the upper 90s and low 100s across much of the region. There will be plenty of sunshine and temperatures in the upper 80s to low 90s. We will still see a few isolated passing showers or inland thunderstorms, but beachgoers, boaters, and anyone planning outdoor workouts, walks, or trips to local parks should be prepared for heat and high humidity.
