High pressure will then begin to build north of the area behind the cold front passage. Southwesterly winds will be in place Friday ahead of the approaching frontal, bringing warm temperatures across inland locations with daytime highs reaching into the the mid to upper 80s, while a weak east coast breeze will keep coastal locations a bit cooler in the low to mid 80s. An influx of moisture from the south/southeast could bring the development of some scattered showers along north central FL locations, where PWATs (Precipitable Waters) are expected around 1.8" to 1.9" range. By the overnight hours temperatures will be in the lower 60s across SE GA and the mid to upper 60s along inland NE FL, with mid 60s to lower 70s along the coast. The building high pressure north of the area will result in strong north/northeast winds to develop over the local waters and towards coastal locations on Saturday. Winds of 15 to 25 mph and gusts of around 35 mph will be possible beginning Saturday afternoon, and persisting through the overnight hours into Sunday, with coastal showers also likely. After the passage of the cold front, cooler temperatures will bring daytime highs will range in the 70s, with warmer temperatures by the coast and north central FL.

Winds continue to be expected around the mid 20 mph range, with gusts possibly in the 35 to 40 mph along the coast and offshore waters, with winds beginning to decrease heading into midweek. The elevated onshore flow will bring coastal hazards such as tidal flooding, rip currents, high surf, and minor to moderate beach erosion. Winds will begin to taper off by midweek as the high pressure begins to weaken. Temperatures will be below average during the period, with daytime highs around the mid to upper 70s during the weekend, upper 70s to lower 80s by next week.
