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

- Patchy Fog Saturday Morning over North Central FL. Patchy fog potential each morning this weekend

- Extreme to Exceptional Drought Continues. Dry & Near Record Warmth Into the Weekend. Critically Low Minimum Humidity Values Inland Each Day. Dry Conditions Will Support Increase Risk of Fire Spread

- Fire Weather Watch Monday Afternoon. Set for Portions of Inland Northeast Florida

- Gusty Coastal & Hazardous Boating Conditions Next Week

NEAR TERM /THROUGH SATURDAY/

Main Highlights Rest of Today and Tonight:

- Near Record warmth today

- Elevated wildfire risk

- Patchy, shallow fog potential late tonight, northeast FL

Clear skies, dry weather, and warm temperatures will persist as surface high pressure remains in place over the FL peninsula to end the work week. A west to southwesterly flow, with wind speeds around 10 mph, will allow for the Gulf breeze to push towards inland locations by the afternoon hours, while the Atlantic breeze pushes into the I-95 corridor by mid to late afternoon. Clear skies will leave the door open for hot temperatures to continue to be above seasonal norms, with some locations likely to get near or break Record Highs as much of the inland locations will rise to the lower to mid 90s. The Atlantic breeze will help to keep our coastal locations relatively cooler in the upper 80s. Bone dry out there with dewpoint depressions as much as 40 deg. Lows tonight will be in the upper 50s to lower 60s along inland locations, while coastal locations will mainly be in the lower 60s.

Patchy, shallow fog possible mainly for northeast FL late tonight as Gulf flow from the west coast sea breeze brings in some shallow moisture. Instances of fog looks to be more isolated than the prior couple of nights.

SHORT TERM /SATURDAY NIGHT THROUGH SUNDAY NIGHT/

Main Highlights This Period:

- Patchy fog NE FL Saturday and Sunday mornings - Critically low minimum humidity values inland SE GA Saturday

High pressure ridge will move off the south southeast through the day Saturday. A cold front will move southeast across area Saturday night through Sunday. This front will pass through largely dry. Best chance for a few spotty showers will be over SE GA Sunday afternoon.

As high pressure builds to the northwest Sunday night, the gradient between the exiting front and the building high will result in elevated winds, especially and gusty winds at the coast. A few coastal showers will be possible due to weak troughs moving ashore Sunday night.

Temperatures will trend above normal this period.

LONG TERM /MONDAY THROUGH FRIDAY/

Main Highlights This Period:

-Elevated and gusty coastal winds Monday

High pressure will build to the northwest then north Monday. Winds will remain elevated and gusty Monday due to the pressure gradient. The core of the elevated winds will be over NE FL, with the highest winds at the coast.

The high will then build to the northeast Monday night into Tuesday. The high will be centered to the east Wednesday through Friday.

This is expected to be a dry period.

Temperatures will be below normal Monday through Tuesday night, then recover to above normal levels later in the week.

AVIATION /00Z SATURDAY THROUGH 00Z SUNDAY/

VFR conditions this evening. Light fog possible toward 08Z-12Z Sat but confidence and duration are uncertain, if any formation does occur it would mainly be confined to inland locations. Light winds return around 13Z/14Z.

MARINE

Surface high pressure ridging will be south of the area into Saturday night. Atlantic sea breeze expected this afternoon and Saturday afternoon shifting winds to the southeast and south up to 15 knots. A dry cold frontal passage is expected late Sunday afternoon into Sunday Night, then a surge of northeast winds follows the frontal passage through Monday night and Small Craft Advisory with the potential for Gale force gusts are expected. High pressure will develop over the area Tuesday, moving east of the area by Wednesday.

Rip Currents and Surf:

Moderate Risk of Rips will continue for area beaches primarily due to the easterly swells of about 2 to 2.5 ft with periods of 8 seconds. A small window of wind wave action each day into the weekend as the Atlantic sea breeze develops during the aftn. The swells don't change appreciably next couple of days so a moderate risk will probably linger through the weekend. High risk of rips and potential high surf advisory conditions expected early next week in strong NE wind surge behind cold frontal passage.

FIRE WEATHER

-Inland MinRH levels at or below 30 percent north of Interstate 10 Saturday -Inland MinRH levels at or below 30 percent Monday through Friday, with MinRH levels below 20 percent over interior SE GA Monday and Tuesday

-Areas of high daytime inland dispersions Saturday

-Widespread high daytime dispersions Sunday through Friday

Outside of a mainly dry front passing through on Sunday, high pressure will be the main weather feature influencing the weather this period with dry pattern continuing.

FOG POTENTIAL AND OTHER REMARKS: Patchy fog potential NE FL Tonight and Saturday night. Winds look a little light for a Red Flag over interior SE GA Saturday, but close. Significant potential for Red Flag criteria to be met over interior NE FL on Monday.
