CONDITIONS DEVELOP THROUGH MONDAY. HIGH, BATTERING SURF REACHING
LOCAL BEACHES WEDNESDAY 7-12 FT BREAKERS
- ISOLATED TSTORMS ALONG THE I-95 CORRIDOR 4-8 PM TODAY
- PATCHY FOG ACROSS INLAND NORTH CENTRAL FL EARLY MONDAY
- SMALL CRAFT ADVISORY IN EFFECT MONDAY THROUGH TUESDAY NIGHT.
FREQUENT GALE FORCE WIND GUSTS DEVELOP WEDNESDAY
- EXTREME TO EXCEPTIONAL DROUGHT CONDITIONS CONTINUE AREA-WIDE
NEAR TERM /THROUGH TONIGHT/
MAIN HIGHLIGHTS THROUGH TONIGHT:
- ISOLATED THUNDERSTORMS THIS AFTERNOON, ESPECIALLY ALONG THE I-95
CORRIDOR
- HIGH RISK OF RIP CURRENT RISK AT THE LOCAL BEACHES TODAY
- NEAR RECORD HIGH TEMPERATURES INLAND
- PATCHY POSSIBLE FOR INLAND NORTH-CENTRAL FL EARLY MONDAY
WEAKENING SURFACE RIDGING CONTINUING TO NUDGE FURTHER EASTWARD TODAY
AHEAD OF AN APPROACHING FRONT, WHICH HAS INDUCED A VERY WARM
SOUTHWESTERLY FLOW ACROSS MUCH OF THE AREA, WITH THE EXCEPTION OF
CLOSER TO THE MARITIME INFLUENCE BY THE COAST. WITH BOTH THE
APPROACHING FRONT AND SOUTHWESTERLY GULF SEA BREEZE PROGRESSING
INLAND THIS AFTERNOON COMBINED WITH HIGHER LOW LEVEL MOISTURE,
SCATTERED SHOWERS AND A FEW ISOLATED THUNDERSTORMS ARE EXPECTED TO
DEVELOP LATER THIS AFTERNOON. PRIMARY AREAS TO WATCH FOR DEVELOPMENT
THROUGH THIS EVENING WILL BE INLAND SOUTHEAST GA CLOSER TO THE
PROGRESSING FRONT, AND TOWARDS THE EAST COAST AND I-95 CORRIDOR
WHERE THE GULF SEA BREEZE COLLIDES WITH THE NEARLY PINNED EAST COAST
BREEZE. WITH SOME LINGERING DRIER AIR ALOFT, NOT EXPECTING
SIGNIFICANT VERTICAL DEVELOPMENT WITH CONVECTION TODAY, THOUGH ANY
THUNDERSTORM THAT DOES FORM WILL HAVE A SLIGHT POTENTIAL FOR A GUSTY
DOWNBURST AROUND 40-50 MPH THANKS TO SOME OF THIS DRY AIR
ENTRAINMENT. ELSEWHERE, SHOWERS WILL BE MOSTLY ISOLATED TO WIDELY
SCATTERED WHERE FORCING/LIFT IS NOT AS ENHANCED. MANY LOCATIONS ARE
ALREADY SEEING TEMP READINGS IN THE 80S, WITH SOME READINGS AROUND
90 QUITE POSSIBLE BY LATE THIS AFTERNOON AND EARLY THIS EVENING.
TONIGHT, THE COLD FRONT PROGRESSES THROUGH THE REGION, PERSISTING A
FEW ISOLATED SHOWERS FROM NORTHWEST TO SOUTHEAST OVERNIGHT AS IT
DROPS JUST SOUTH OF THE AREA BY MONDAY MORNING. WINDS WILL ALSO
SHIFT TOWARDS THE NORTHWEST TO NORTH OVERNIGHT AS HIGH PRESSURE
BUILDS IN FROM THE NORTH, THOUGH NOT EXPECTING A SIGNIFICANT
INCREASE IN WINDS UNTIL DURING THE DAY MONDAY. SOME PATCHY FOG WILL
ALSO BE POSSIBLE TOWARDS SOUTHERN PORTIONS OF THE AREA EARLY MONDAY
MORNING WHERE THE HIGHEST SURFACE MOISTURE LINGERS. LOWS TONIGHT
WILL RANGE FROM THE UPPER 50S TO NEAR 60 OVER SOUTHEAST GA TO THE
LOW TO MID 60S OVER NORTHEAST FL.
SHORT TERM /MONDAY THROUGH TUESDAY NIGHT/
MAIN HIGHLIGHTS THIS PERIOD:
- COOLER WITH BREEZY TO WINDY ONSHORE FLOW MONDAY AND TUESDAY
- HIGH RISK OF RIP CURRENTS AND HIGH SURF FOR THE ATLANTIC COAST
- MOSTLY BENEFICIAL RAINFALL FOR PORTIONS OF NORTHEAST FLORIDA
THE COLD FRONT WILL BE SOUTH OF THE AREA BY MONDAY MORNING, THEN
STALLING OVER CENTRAL FLORIDA AS ANOTHER FRONT SLOWLY APPROACHES
FROM THE NORTH ON TUESDAY. ENOUGH MOISTURE WILL REMAIN OVER THE AREA
ON MONDAY AND TUESDAY TO PROMPT SCATTERED TO NUMEROUS SHOWERS MAINLY
OVER NORTHEAST FLORIDA BOTH DAYS. INSTABILITY WILL BE LOW DUE TO
ENHANCED CLOUD COVER AND WILL LIMIT THUNDERSTORM ACTIVITY, BUT
CANNOT RULE OUT ISOLATED STORMS OVER THE NE FL COASTAL WATERS,
POSSIBLY REACHING ST. JOHNS/FLAGLER COUNTIES WITH SOME HEAVY
DOWNPOURS AS WELL. FOLLOWING THE FRONTAL PASSAGE, THE LOCAL PRESSURE
GRADIENT WILL INCREASE AS HIGH PRESSURE SITS TO OUR NORTHEAST,
BRINGING BREEZY/WINDY ONSHORE FLOW THROUGH THIS PERIOD. WIND GUSTS
MONDAY WILL LIKELY STAY BELOW BELOW WIND ADVISORY CRITERIA IN THE 30-
40 MPH RANGE, BUT SOME MODEL GUIDANCE SUGGESTS POTENTIAL FOR WIND
ADVISORY CONDITIONS BY TUESDAY INTO TUESDAY NIGHT ALONG THE NE FL
COAST AND ST. JOHNS RIVER BASIN FOR SUSTAINED NE WINDS OF 25-30 MPH
AND PEAK WIND GUSTS OF 40-45 MPH AND THESE MAY NEED TO BE POSTED.
AFTER A HOT WEEKEND, TEMPERATURES WILL COOL DOWN MONDAY AND TUESDAY,
HIGHS GENERALLY IN THE 70S. A HIGH RISK OF RIP CURRENTS WILL
CONTINUE ALONG THE ENTIRE ATLANTIC COAST, ALONG WITH BUILDING SURF,
LIKELY REQUIRING A HIGH SURF ADVISORY BY TUESDAY WITH BREAKERS OF 6
TO 8 FEET. ELEVATED WATER LEVELS ARE EXPECTED AT TIMES OF HIGH TIDE,
BUT ARE EXPECTED TO REMAIN BELOW MINOR FLOOD LEVELS AT THIS TIME.
RAINFALL AMOUNTS WILL GENERALLY BE ON THE LIGHT TO MODERATE SIDE
THIS PERIOD, WITH TOTALS LESS THAN 0.25" ACROSS SE GA, AROUND 0.50"
ACROSS INLAND NE FL AND 1-2" ALONG THE NE FL COASTAL COUNTIES SOUTH
OF JAX ALONG THE I-95 CORRIDOR, WITH LOCALLY HIGHER AMOUNTS POSSIBLE
IN ST. JOHNS AND FLAGLER COUNTIES. MOST OF THIS WILL BE BENEFICIAL
RAINFALL TO HELP THE CURRENT EXTREME DROUGHT SITUATION, BUT SOME
BRIEF LOCALIZED FLOODING WILL BE POSSIBLE IN URBAN AREAS AND IF IT
OCCURS DURING TIMES OF HIGH TIDE ALONG THE ATLANTIC COAST.
LONG TERM /WEDNESDAY THROUGH SUNDAY/
MAIN HIGHLIGHTS THIS PERIOD:
-STRONG ONSHORE FLOW WEDNESDAY AND THURSDAY, WITH ELEVATED WINDS
ALONG THE COAST AND INLAND TO THE ST. JOHNS RIVER BASIN
- MOSTLY BENEFICIAL RAINFALL POTENTIAL FOR COASTAL NORTHEAST FL
STRONG ONSHORE WINDS CONTINUE THROUGH THE END OF THE WEEK, WITH
GUSTS WEDNESDAY AND THURSDAY ALONG THE ATLANTIC COAST LIKELY INTO
WIND ADVISORY CRITERIA (UP TO 40-50 MPH). SEVERAL DAYS OF GUSTY
NORTHEASTERLY WINDS WILL CREATE BEACH AND MARINE HAZARDS, INCLUDING
HIGH SURF UP TO 8-12 FEET, MODERATE BEACH EROSION AND POTENTIAL
MINOR COASTAL FLOODING AT TIMES OF HIGH TIDE. CONDITIONS TO IMPROVE
NEXT WEEKEND AS THE PRESSURE GRADIENT WEAKENS. RAIN AND ISOLATED
STORM CHANCES EACH DAY WILL PRIMARILY BE OVER COASTAL NORTHEAST
FLORIDA WITH LOCALLY HEAVY RAINFALL POSSIBLE, BUT OVERALL WILL BE
MOSTLY BENEFICIAL DUE TO THE CURRENT DROUGHT. TEMPERATURES WILL BE
BELOW NORMAL WEDNESDAY AND THURSDAY WITH MOSTLY CLOUDY SKIES, AND
WILL WARM UP TO NEAR NORMAL BY FRIDAY AND BACK TO ABOVE NORMAL
LEVELS INTO THE UPCOMING WEEKEND.
RAINFALL AMOUNTS THIS PERIOD STILL GENERALLY 0.25" OR LESS ACROSS SE
GA, 0.50"-1.00" INLAND NE FL AND 1-3" FOR COASTAL NE FL COUNTIES
WITH LOCALLY HEAVIER AMOUNTS ALONG THE I-95/US-17 CORRIDORS, MAINLY
TO THE SOUTH OF JAX. STILL MAINLY OF THE BENEFICIAL NATURE, BUT AS
RAINFALL TOTALS ADD UP FOR ST. JOHNS/FLAGLER COUNTIES, SOME BRIEF
PERIODS OF LOCALIZED/URBAN FLOODING IS POSSIBLE, ESPECIALLY DURING
TIMES OF HIGH TIDE ALONG THE ATLANTIC COAST.
AVIATION /12Z SUNDAY THROUGH 12Z MONDAY/
AREAS OF FOG WITH MVFR TO IFR RESTRICTIONS WILL CONTINUE
THROUGH ABOUT 13 TO 14Z BEFORE RATHER QUICKLY DISSIPATING.
OTHERWISE, VFR RETURNS FOR MOST OF THE FORECAST PERIOD AS ONLY
SOME DIURNAL CUMULUS AND MID/HIGH CLOUDS WITH AN APPROACHING
FRONTAL BOUNDARY FILL IN LATER THIS MORNING AND AFTERNOON. SOME
SHRA AND ISOLATED TSRA WILL BE POSSIBLE BOTH AHEAD OF THE FRONT,
WITH THE HIGHEST CHANCES FOR TSRA BEING AT COASTAL TERMINALS
THIS AFTERNOON IN THE VICINITY OF THE NEARLY PINNED SEA BREEZE.
THIS SEA BREEZE IS EXPECTED TO MAKE IT AS FAR INLAND AS JAX BY
THIS EVENING WITH A WIND SHIFT FROM SOUTHWEST TO SOUTHEAST. THE
AFOREMENTIONED FRONT MOVES THROUGH LATE IN THE FORECAST PERIOD,
WITH WINDS QUICKLY VEERING TOWARDS THE NORTH OVERNIGHT AND SOME
LOWER CLOUDS IN THE 035 TO 050 RANGE LINGERING AS WELL.
MARINE
SOUTH TO SOUTHEASTERLY WINDS WILL CONTINUE TODAY AHEAD OF AN
APPROACHING COLD FRONT, WHICH WILL MOVE ACROSS AREA WATERS TONIGHT.
SCATTERED SHOWERS AND ISOLATED THUNDERSTORMS WILL BE EXPECTED THIS
AFTERNOON AND EVENING, AND PERSISTING THROUGH TONIGHT. ONSHORE WINDS
RETURN MONDAY AND PERSIST THROUGHOUT THE WEEK BEHIND THE FRONT,
STRENGTHENING TO SMALL CRAFT ADVISORY ACROSS THE AREA MONDAY AND
POSSIBLY REACHING GALE WARNING CRITERIA BY TUESDAY/WEDNESDAY.
PERIODS OF SHOWERS AND ROUGH SEAS WILL ALSO ACCOMPANY THE RETURNING
ONSHORE FLOW THROUGHOUT THE WEEK.
RIP CURRENTS:
BREEZY SOUTH TO SOUTHEAST WINDS AT THE COAST, COMBINED WITH SURF
AROUND 3 TO 5 FEET WILL PERSIST A HIGH RISK OF RIP CURRENTS THROUGH
TODAY. FAST-MOVING LONGSHORE CURRENTS ARE ALSO EXPECTED. THROUGHOUT
THE WEEK AHEAD, SURF ZONE WILL BECOME HAZARDOUS WITH A HIGH RISK OF
STRONG RIP CURRENTS EACH DAY FROM MONDAY THROUGH FRIDAY AND HIGH,
ROUGH SURF DEVELOPING BY TUESDAY. GIVEN THE BATTERING SURF, MINOR
BEACH EROSION IS POSSIBLE AFTER DAYS OF ROUGH SURF LATER THIS WEEK.
FIRE WEATHER
- HIGH AFTERNOON DISPERSIONS INLAND SE GA TODAY AND TUESDAY
- CRITICALLY LOW MIN RH AND BREEZY INLAND SE GEORGIA TUESDAY
A FRONTAL BOUNDARY WILL APPROACH THE AREA THIS AFTERNOON AND MOVE
THROUGH TONIGHT, WHICH WILL BRING MORE OF A SOUTHWEST FLOW EXCEPT
NEAR THE COAST AND THE RETURN OF SHOWER & T'STORM CHANCES, MAINLY
OVER INLAND GA AND NEAR THE I-95 CORRIDOR TO THE COAST WHERE THE
BEST CONVERGENCE IS EXPECTED. AREAS OF HIGH DISPERSIONS WILL BE
LIKELY ACROSS INLAND SOUTHEAST GA AHEAD OF THE FRONT WHERE THE
STRONGEST LOW/MID LEVEL WINDS ARE EXPECTED. MUCH STRONGER HIGH
PRESSURE BUILDS IN FROM THE NORTH FOR MONDAY AND REMAINS PERSISTENT
THROUGH MID WEEK, RETURNING BREEZY TO WINDY ONSHORE FLOW AND MOSTLY
CLOUDY CONDITIONS WITH CHANCES FOR SHOWERS THE CLOSER TO THE COAST.
CRITICALLY LOW MINRH VALUES AND BREEZY WINDS ARE FORECAST TUESDAY
FOR PORTIONS OF INLAND SOUTHEAST GEORGIA, AND A POTENTIAL EXISTS FOR
RED FLAG CONDITIONS, DEPENDING ON HOW MUCH RAINFALL OCCURS WITH THE
FRONTAL PASSAGE TONIGHT. MOISTURE LEVELS WILL RETURN ABOVE CRITICAL
LEVELS THE REMAINDER OF THE WEEK, BUT BREEZY EASTERLY FLOW WILL
CONTINUE THROUGH FRIDAY.
FOG POTENTIAL AND OTHER REMARKS: PATCHY FOG POTENTIAL MONDAY MORNING
FOR NORTH CENTRAL FLORIDA. OTHERWISE FOG POTENTIAL REMAINS LOW
THROUGH MOST OF THE UPCOMING WEEK DUE TO THE INCREASED WINDS.
