South Florida will see typical September weather this weekend — sun, showers, storms. Saturday features some early passing showers along the east coast, highs around 90 degrees in Miami-Dade and Broward, and in the low 90s in the Naples and Marco Island areas, some afternoon storms in the western suburbs of Miami-Dade and Broward, and more widespread afternoon storms along the Gulf coast and in the interior. The Keys will see more storms, periods of heavy rain, and gusty winds on Saturday into Sunday as an area of disturbed weather moves westward in the Straits of Florida.
For the rest of South Florida, Sunday will bring some early east coast showers, a few afternoon storms in the western metro areas of Miami-Dade and Broward, and more extensive afternoon storms along the Gulf coast. Sunday’s highs will be around 90 degrees along the east coast and in the low 90s on the Gulf coast.
We’ll see some passing showers and storms on Monday, with most of the activity along the Gulf coast during the afternoon. Monday’s highs will be in the upper 80s.
All of South Florida will see some passing showers and storms on Tuesday, and highs will be in the upper 80s.
A few afternoon storms are in the forecast for Miami-Dade and Broward on Wednesday, but the Gulf coast will see widespread showers and storms. Wednesday’s highs will be near 90 degrees along the east coast and in the upper 80s in the Naples and Marco Island areas.
That small area of disturbed weather in the Straits of Florida will bring gusty winds and thunderstorms to the Keys. The National Hurricane Center gives the disturbance a low chance of developing into a depression over the next couple of days as it heads into the Gulf of Mexico, where it will encounter unfavorable winds.
Elsewhere in the tropics, the wave that’s just north and west of the Lesser Antilles is disorganized and has a low chance of developing over the next 5 days.
And the wave that’s now about 1000 miles east of the Lesser Antilles has a high chance of developing into a depression over the next 5 days as it moves west-northwestward and then northwestward in the central Atlantic. It’s not likely to be a threat to land.
