- Areas of Fog Again Tonight/Friday Morning

- Minor River Flooding Continues Along Lower Portions of the Satilla River

- Marine & Coastal Hazards Return this Weekend. Dangerous Surf Zone Conditions - High Risk for Rip Currents & Rough, High Surf. Small Craft Advisory, Potential Gusts to Gale Force Sunday into Monday. Minor Tidal Flooding Potential at Coast, ICW & St. Johns Basin. Extended duration minor flooding along St Johns River into next week possible

NEAR TERM /UNTIL 7 AM FRIDAY MORNING/

Main Highlights through Tonight:

- Patchy to Areas of Fog, locally dense Late Tonight

Surface high pressure ridge will weaken over the area through Tonight. Fog is expected to develop again Tonight, and may become locally dense. Temperatures will remain above average.

SHORT TERM /7 AM FRIDAY MORNING THROUGH SATURDAY NIGHT/

Main Highlights This Period:

- Potential for a few storms over north central FL Friday afternoon/evening

-Coastal hazards begin late Friday night into Saturday with beginning stages of elevated water levels, high rip current risk, and rough surf and seas.

- Northerly winds expected to gust to around 35 mph on Saturday and Saturday night, with a potential for gusts of 40 mph along the coastal areas of northeast FL, which would necessitate a wind advisory along the coast

A cold front pushes into the area from the northwest Friday evening, shifting south of the area by Saturday morning. 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 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. Overnight Lows will be in the lower 50s to mid 60s, warmer temperatures again over north central FL and coastal locations.

LONG TERM /SUNDAY THROUGH THURSDAY/

Main Highlights This Period:

- Coastal hazards including tidal flooding, gusty winds, elevated rip risk and surf expected from Sunday through Tuesday

High pressure over the north and then the northeast of the area will continue to bring strong winds through the end of the weekend into the upcoming week across the local waters and coastal locations, with chances of showers also persisting for these locations. 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.

AVIATION /00Z FRIDAY THROUGH 00Z SATURDAY/

Patchy to areas of fog are expected to develop again Tonight, with restrictions expected. This fog will lift after sunrsie, with a trend to VFR starting mid morning. A few thunderstorms are possible Friday afternoon over north central FL, which may reach KSGJ later in the afternoon. The chance is too low for a KSGJ storm to include more than a VCTS at this time.

MARINE

High pressure will be over the area Today, then weaken as it shifts east northeast of the area Tonight into Friday. A cold front will move southeast across the area Friday night. Strong high pressure will build behind the front. A surge of north winds will move south down the coastal waters behind the front, with elevated winds from late Friday night through much of next week, with potential for Gale force winds late Saturday into Monday.

Rip Currents: Low to Moderate risk through Friday. High risk of rip currents with rough surf from Saturday through much of next week.

FIRE WEATHER

- Patchy Low Daytime Dispersions This Afternoon - Patchy High Afternoon Dispersions Friday Through Monday

High pressure remains over the area into Friday, with easterly winds persisting today. Southwesterly winds develop on Friday ahead of an approaching cold front. The cold front will push through the area by Friday night. Northeasterly winds develop this weekend behind the cold front as high pressure builds north of the area. Elevated winds are expected along the Atlantic coast of SE GA and NE FL beginning late Friday Night, with the elevated winds persisting into the upcoming week. This will bring chances of showers for coastal locations through the weekend and next week.

Poor to Fair dispersions persist this afternoon. By Friday, Good to High dispersions develop over SE GA ahead of the frontal boundary, with Fair to good dispersions expected over NE FL.

FOG POTENTIAL AND OTHER WEATHER REMARKS: Areas of dense fog is possible late tonight and early Friday morning hours. This will mainly be over inland areas and Dense Fog Advisories may be required. There is a low chance for thunderstorms over north central FL Friday afternoon.

HYDROLOGY

Minor flooding will continue along lower portions of the Satilla River during the next several days.

TIDES/COASTAL FLOODING

Minor tidal flooding is possible along the Atlantic coast, ICWW, and St. Johns river basin this weekend and early next week as strong northeasterly winds develop. Some significant beach erosion is possible by Sunday, especially coastal northeast FL, as seas for the nearshore waters build to the 10-15 ft range through Monday night while southeast GA nearshore seas mainly in the 8-13 ft range.
