SYNOPSIS
High pressure northeast of Florida will keep southeast flow in place through Monday, turning onshore near the coast in the afternoon with the sea breeze. Winds will generally remain less than 15 knots outside of daily thunderstorms. Tuesday through the rest of the week, the ridge will shift south and will extend across the Florida Peninsula into the eastern Gulf, bringing in drier air aloft with lower rain chances and keeping winds and seas below headline criteria.
