WEST PALM BEACH, Fla. — Look for a warm and humid start across South Florida on Monday, with temperatures quickly climbing through the 80s. Afternoon highs will reach around 90 to 92 degrees, with heat index values potentially reaching the low 100s in some areas.
Light winds will allow both the Atlantic and Gulf coast sea breezes to move inland during the afternoon. As those boundaries interact, scattered showers and thunderstorms will develop, with the greatest concentration of storms expected over the interior.
For the Palm Beaches, rain chances generally range from about 40% near West Palm Beach and coastal areas to 60% inland. Along the Treasure Coast, rain chances are somewhat lower, around 40% in Vero Beach and Fort Pierce.

Changes begin Tuesday and Wednesday as high pressure strengthens north of Florida and winds turn more easterly to northeasterly. That will bring a stronger Atlantic breeze and help push temperatures slightly closer to normal.
Gusty winds over the Atlantic will help bring showers to the east coast before they quickly push inland.
Boating conditions will be beautiful on Monday ( outside of any showers and storms) Seas 1-2' and smooth conditions on the Intracoastal.
However by Wednesday - wave heights will increase to 3-5 feet and occasionally up to 6'
