SHORT TERM /FRIDAY THROUGH SUNDAY NIGHT/
MAIN HIGHLIGHTS THIS PERIOD:
- HIGH RISK FOR RIP CURRENTS & ELEVATED SURF PERSIST AT BEACHES
- PATCHY INLAND FOG POSSIBLE INLAND DURING THE MORNING HOURS THIS
WEEKEND
A TRANSITION TO A WARMING, MOSTLY SUNNY, AND DRY CONDITIONS WILL
OCCUR THROUGH THE WEEKEND. LOW LEVEL RIDGING WILL PROMOTE AN ONSHORE
BREEZE EACH DAY WHILE UPPER RIDGE BEGINS TO STACK OVER THE FORECAST
AREA THROUGH SUNDAY. FORECAST SOUNDINGS INDICATE THAT A PROMINENT
DRY AIRMASS IN ABOVE 850MB WILL NEGATE ANY ATTEMPTS OF BUILDUPS
ALONG THE ATLANTIC SEA BREEZE.
HIGHS FRIDAY WILL MODERATE TO NEAR NORMAL ALONG THE COAST IN THE MID
70S WITH HIGHS BUMPING ABOVE NORMAL INTO THE LOWER 80S. AS RIDGING
BUILDS OVERHEAD, TEMPERATURES WILL WARM 2-4 DEGREES OVER THE

BE CONDITIONS FAVORABLE FOR SHALLOW FOG DEVELOPMENT TOWARD DAYBREAK
SATURDAY AND SUNDAY MORNINGS.
LONG TERM /MONDAY THROUGH WEDNESDAY/
MAIN HIGHLIGHTS THIS PERIOD:
- WARMING TEMPERATURES AND FAIR SENSIBLE WEATHER
- ELEVATED TO HIGH WILDFIRE DANGER WILL BE POSSIBLE INLAND EACH DAY
PROLONGED PERIOD OF DRY AND ABOVE NORMAL TEMPERATURES THROUGH NEXT
WEEK AS STUBBORN UPPER RIDGING REMAINS ANCHORED OVER THE FORECAST
AREA AT LEAST WEDNESDAY BEFORE BREAKING DOWN. THIS WILL FAVOR
CONTINUED WARMING TREND WITH INLAND HIGHS FLIRTING WITH 90 DEGREES
AGAIN BY THE MIDDLE OF NEXT WEEK. THESE WARM TEMPERATURES WILL
INTENSIFY THE THERMAL TROUGH, ENHANCING THE WINDS ASSOCIATED WITH
THE ATLANTIC SEA BREEZE. HOTTER AND RAIN-FREE CONDITIONS MAY ENHANCE
LOCAL WILDFIRE DANGER NEXT WEEK DUE MULTIPLE DAYS OF LOW AFTERNOON
HUMIDITY AND CRITICALLY DRY FUELS.
AVIATION /12Z THURSDAY THROUGH 12Z FRIDAY/
NE WINDS CONTINUE THROUGH THE PERIOD, WITH MVFR CEILINGS THROUGHOUT
THE DAY AS CONVECTION WILL PRIMARILY BE FOCUSED OVER SOUTHERN
LOCATIONS AROUND SGJ THROUGH THE AFTERNOON AND THEN BECOMING
DISPERSED BY AROUND 00Z. GUSTY WINDS WILL PERSIST THROUGH A MAJORITY
OF THE FORECASTED PERIOD WITH STRONGER WINDS AFFECTING COASTAL
SITES, WITH WINDS TAPERING OFF BY 05Z FOR INLAND SITES.
MARINE

TODAY, WITH AN INVERTED TROUGH TO THE SOUTH. THE HIGH WILL WEAKEN AS
IT SETTLES OVER THE SOUTHEASTERN US ON FRIDAY. THE HIGH WILL MOVE
OFF TO THE NORTHEAST OVER THE WEEKEND, AND MORE TOWARD THE EAST
NORTHEAST NEXT WEEK.
RIP CURRENTS AND SURF: A REINFORCED SURGE OF ONSHORE WINDS WILL
KEEP A HIGH RISK OF RIP CURRENTS THROUGH THURSDAY. AS THE
STRONGEST WINDS DURING THIS EVENT ARRIVE TODAY BREAKERS WILL
RISE TO 10-13 FEET. THE SURF ZONE WILL BE A VERY DANGEROUS AND
BECOME LIFE-THREATENING TO ANY SWIMMER REGARDLESS OF EXPERIENCE.
GIVEN THE HIGH BREAKERS, MINOR BEACH EROSION WILL BE POSSIBLE.

- LOWERING HUMIDITY TREND INLAND THIS WEEKEND AND NEXT WEEK
BREEZY EASTERLY WINDS WILL CONTINUE BUT BE MUCH LIGHTER THAN
YESTERDAY, WITH GUSTS 20 TO 25 MPH INLAND AND UP TO 30 MPH AT THE
COAST. HUMIDITY WILL FALL NEAR 30 PERCENT FOR PORTIONS OF SOUTHEAST
GA, NORTHWEST OF WAYCROSS, AND COMBINE WITH BREEZY CONDITIONS TO
ELEVATE FIRE DANGER. TEMPERATURES WILL TREND WARMER AND INLAND
AFTERNOON HUMIDITY LOWER THROUGH THE WEEKEND AND INTO NEXT WEEK AS
AN UPPER LEVEL RIDGE BUILDS OVER FL AND GA. LOW HUMIDITY AND A GUSTY
EASTERLY SEA BREEZE IS LIKELY TO SET UP ELEVATED FIRE WEATHER
CONDITIONS THROUGHOUT NEXT WEEK.

THIS MORNING OR FRIDAY MORNING. PATCHY FOG POTENTIAL INCREASES OVER
THE WEEKEND.
HYDROLOGY
DAYS OF STRONG ONSHORE FLOW HAVE "TRAPPED" TIDAL FLOW IN THE
MIDDLE ST. JOHNS RIVER BASIN. THIS HAS PUSHED TIDE GAUGES TO
READ AT "ACTION" LEVELS. THE NEXT HIGH TIDE IS LIKELY TO RAISE
THE STAGE TO "MINOR" FLOOD LEVELS DURING THE MID TO LATE MORNING
HOURS FOR PORTIONS OF THE RIVER SOUTH OF THE BUCKMAN BRIDGE. A
COASTAL FLOOD ADVISORY HAS BEEN ISSUED TO HIGHLIGHT ELEVATED
TIDAL LEVELS THIS MORNING. THIS WILL BE REVISITED TO ADDRESS THE
POTENTIAL FOR FLOODING DURING THE EVENING HIGH TIDE, ONCE WE
ASSESS THIS MORNING'S TIDAL BEHAVIOR ON THAT STRETCH OF THE
RIVER. ONLY MINOR IMPACTS ARE EXPECTED WITH WATER LEVELS AT
1.5-1.75 FEET ABOVE NORMALLY DRY GROUND.
