Marine Weather and Tide Forecast for Greenbriar, FL

DISCUSSION
Issued at 134 PM EDT Sat Apr 18 2026 High pressure aloft remains centered over the Gulf this afternoon while the surface ridge axis extends across the central part of Florida. This pattern will keep warm and dry conditions across the region through Sunday, then we get a weak frontal boundary late Sunday into Monday. This front will bring a slight chance for showers on Monday afternoon, mainly for interior locations south of I-4, but forecast rainfall amounts remain low. Temperatures return a little closer to normal behind the boundary, along with lower humidity, and generally hold there through the week.

A weak cold front will move through the area on Monday, with very limited rainfall. Drier air behind this boundary will move into mainly Levy County by Monday afternoon and winds may get close to 15 mph, so will have to watch that area for Red Flag conditions. Drier air extends across the rest of the region Tuesday afternoon, with breezy winds leading to another day of higher fire danger.
