For the latest NE FL and SE GA Daily Key Messages please visit: https:/www.weather.gov/media/jax/briefings/nws-jax-briefing.pdf

- Fog Possible Each Morning through Saturday. Friday Morning: Coastal locations and I-95 corridor

- Near Record Warmth through Saturday

- Extended Dry Spell Continues through Early Next Week. Be very cautious with outdoor fires, check for local burn bans. Severe to Extreme Drought Expanding Across Inland Southeast GA and the Suwannee Valley Region

NEAR TERM /THROUGH TONIGHT/

Weak high pressure ridge will be over the region Tonight. Dewpoints over the coastal waters will rise to levels that will be at or above the water temperature. This setup will lead to fog development after sunset along the coast, with this fog spreading inland through the night. Beach front communities could have low visibilities beginning as early as sunset. Dense fog advisories may become necessary, especially for coastal counties.

Lows will trend above seasonal averages Tonight.

SHORT TERM /FRIDAY THROUGH SATURDAY NIGHT/

High pressure over the area begins to shift away from the FL peninsula on Friday as a frontal boundary begins to push towards the southeastern CONUS. The frontal boundary pushes into the area on Saturday.

Lingering fog along coastal locations will begin to lift and clear by the mid morning hours on Friday. The persistent southwesterly flow ahead of the front will continue to bring in moisture and warmer temperatures across the area on Friday. There will be an increase in cloud cover compared to the past couple of days. Friday daytime highs will again reach into the low and mid 80s across inland locations, while upper 70s along the coast as a weak sea breeze develops during the afternoon hours. Overnight lows in the mid to upper 50s across inland locations and the lower 60s along the coast.

Another night of patchy to areas of fog will be in Friday night as lingering moisture from the Gulf will allow for some fog to develop along the I-75 corridor during the early predawn hours on Saturday, with some locally dense fog. Southwest winds will steadily shift to be northwesterly during the overnight hours into Sunday. A similar spread of daytime temperatures compared to Friday with highs in the lower to mid 80s. With the cold front pushing through, overnight lows will be cooler across SE GA locations with lows in the mid to upper 50s and lows in the lower 60s across NE FL.

LONG TERM /SUNDAY THROUGH THURSDAY/

Frontal boundary will clear the area on Sunday. Winds shift to become northeasterly behind the front. Highs on Sunday will mostly be in the upper 70s for most locations, with lower 80s along the I-75 corridor. The northeast to easterly onshore flow will shift to become southwest-southerly during the start of the next week as high pressure centered over the Carolinas extends south towards the southeast CONUS. Guidance is indicating the next frontal boundary to arrive towards the local area by midweek of the upcoming week as the high pressure moves off towards the Atlantic sometime on Tuesday. This front could bring some showers over SE GA and south towards locations along the I-10 corridor in NE FL Wednesday morning. Otherwise, fog development will continue to be of concern during the upcoming week as moisture continues to be brought into the area due to the southerly flow.

AVIATION /18Z THURSDAY THROUGH 18Z FRIDAY/

Fog is expected to develop Tonight. The fog will first develop near the coast around sunset, then move inland through the night. The fog is expected to become dense, and may be slow to lift on Friday morning. Once the fog lifts mid morning on Friday, prevailing VFR conditions will be expected.

MARINE

High pressure ridging over the Florida panhandle will weaken while shifting slowly southeastward by Friday afternoon and Saturday. A weakening and mostly dry frontal boundary will then push southward through the Georgia waters on Saturday night, with this boundary pushing across the northeast FL waters on Sunday morning. High pressure will build east-southeastward from the Upper Midwest on Sunday night towards the Mid-Atlantic states by early Tuesday, with breezy onshore winds developing across our local waters from Sunday afternoon through Monday afternoon. A stronger cold front may then push eastward across the southeastern states next Wednesday and Wednesday night, with southerly winds expected to develop ahead of this front beginning on Tuesday.

Rip Currents: SE GA Moderate Friday NE FL Moderate Friday

FIRE WEATHER

Persistent weather pattern of dry conditions, warm temperatures, and rising afternoon humidity into the upcoming weekend as the drought continues. Lingering low level moisture from the Gulf will continue to bring the potential for morning fog, with some locations with dense fog. Poor afternoon dispersions will also be in play as minimal surface and transport winds remain Friday and Saturday.

Breezy southwesterly winds will start to increase with gusts up to 15 mph across southeast GA on Friday afternoon as a weak cold front slowly approaches from the northwest. Breezy southwesterly winds will spread across the entire area Saturday as the aforementioned front pushes into and through the region overnight Saturday into Sunday. Northeasterly winds behind the front Sunday will trend easterly by Monday. Another cold front will pass through the area during the middle of next week which may offer breezy winds and low relative humidity in its wake.
