Detailed Forecast


Synopsis: A weak, broad dome of high pressure will remain entrenched across the Atlantic, with the associated ridge axis extending across Central Florida. Light to gentle northeast to east breezes are expected through Monday. A swath of enhanced moisture will remain over the Florida Keys coastal waters, resulting in above normal rain chances. A frontal boundary currently over the Gulf coast will push southeastward early next week, with drier conditions anticipated Tuesday and Wednesday. A second frontal boundary will approach the Florida Peninsula on Thursday, resulting in a period of elevated rain and thunder chances.
