Thanks to a tropical wave approaching from the southeast, South Florida likely will see afternoon showers and storms through Saturday.
Wednesday's forecast calls for mostly cloudy skies, highs in the upper 80s, lows in the upper 70s and a 70 percent chance of rain.
The chance of rain remains high on Thursday and Friday and eases slightly on Saturday.
The wave, which isn't likely to develop into a bona fide tropical system, should be over South Florida on Wednesday night, said meteorologist Andrew Kennedy of the National Weather Service in Miami.
"Basically, it will keep sliding to the west over the day on Thursday, so our highest chance of rain is on Thursday and Friday," he said.
Mainly, the wave should bring scattered showers and storms, although it could produce heavy downpours and localized flooding, the weather service said.
For now, the forecast calls for conditions to be drier as of Sunday.
Senior hurricane specialist Lixion Avila said "no significant development" is expected as the wave drifts northward.
