- 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 WEEKEND.

WILL 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 /06Z THURSDAY THROUGH 06Z FRIDAY/
WINDS WILL BUILD IN FROM OUT OF THE NE WITH CEILINGS DROPPING INTO
MVFR LEVELS THROUGHOUT THE DAY WITH DEVELOPING CONVECTION MAINLY
AFFECTING 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.
MARINE
STRONG HIGH PRESSURE WILL BE CENTERED THE NORTH NORTHEAST THROUGH
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:
ONSHORE WINDS WILL KEEP A HIGH RISK OF RIP CURRENTS THROUGH
FRIDAY, AND LIKELY THROUGH THE WEEKEND AS ELEVATED SURF AND
ONSHORE FLOW PREVAIL.
FIRE WEATHER
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.
FOG POTENTIAL AND OTHER REMARKS: SIGNIFICANT FOG IS NOT
EXPECTED 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.
