- GUSTY SOUTHWEST WINDS THIS AFTERNOON INCREASE THE WILDFIRE DANGER.
SUSTAINED SPEEDS OF 15-20 MPH WITH FREQUENT GUSTS OF 25-30 MPH
- MODERATE TO HEAVY SHOWERS LATE TONIGHT THROUGH SATURDAY. FEW STRONG
STORMS POSSIBLE ACROSS SOUTHEAST GA ON FRIDAY. RAINFALL AMOUNTS OF
0.5 2, WITH LOCALLY HIGHER TOTALS POSSIBLE
- MODERATE RISK OF RIP CURRENTS AT ALL AREA BEACHES
- EXTENDED PERIOD OF BREEZY ONSHORE WINDS EXPECTED NEXT WEEK.
INCREASING MARINE HAZARDS LIKELY BY TUESDAY AND WEDNESDAY
NEAR TERM /THROUGH TONIGHT/
HIGH PRESSURE RIDGING AFFECTING THE FORECAST AREA WILL VERY
GRADUALLY SHIFT FURTHER SOUTHWARD AS A MOIST SOUTHWESTERLY FLOW
BUILDING AHEAD OF AN APPROACHING COLD FRONT, PRESSING IN FROM OUT OF
THE NORTH, FORMS OVER THE REGION BRINGING INCREASED CHANCES FOR
LIGHT SHOWERS OVER SOUTHEAST GEORGIA AND NORTHEAST FLORIDA, BECOMING
MORE WIDESPREAD OVERNIGHT AND INTO FRIDAY MORNING. ABOVE AVERAGE
TEMPERATURES THROUGHOUT THE FORECAST AREA THROUGH TODAY AND TONIGHT
WITH DAILY HIGH TEMPS REACHING UP INTO THE MID TO UPPER 70S AND
OVERNIGHT MIN TEMPS DROPPING DOWN INTO THE UPPER 50S.
SHORT TERM /FRIDAY THROUGH SATURDAY NIGHT/
MAIN HIGHLIGHTS DURING THE PERIOD:
- SHOWER AND THUNDERSTORM CHANCES THROUGH SATURDAY, WITH A FEW
STRONG STORMS POSSIBLE.
SHOWER AND T'STORM CHANCES PICK UP FROM NORTH TO SOUTH THROUGHOUT
THE DAY FRIDAY AND INTO FRIDAY NIGHT AS A FRONTAL BOUNDARY SLOWLY
NUDGES SOUTH AND EASTWARD. THE FRONT MOVES SLOW ENOUGH BY FRIDAY
NIGHT THAT THE FEATURE ALMOST STALLS OVER NORTHEAST FL, WHICH WILL
HELP TO MAINTAIN PERIODS OF SHOWERS AND RESULT IN MORE BENEFICIAL
RAINFALL FOR THE REGION. AS FOR DURING THE DAY FRIDAY, EXPECTING
INTERIOR GA TO FEATURE THE MOST "WASHOUT" TYPE OF RAINFALL, WITH
THIS SAME AREA ALSO HAVING THE BEST CHANCES FOR THUNDERSTORMS FRIDAY
AFTERNOON AND EVENING WITH THE BEST DIURNAL HEATING. ANY
STRONG/SEVERE CHANCES ARE LOW AT THIS TIME, THOUGH AN ISOLATED
STRONG STORM CAN'T BE RULED OUT WITH GUSTS AROUND 40-50 MPH LOOKING
LIKE THE MAIN HAZARD. WITH THE NUMEROUS SHOWERS/STORMS AND THE FRONT
CLEARING SOUTHEAST GA DURING THE DAY FRIDAY, THIS WILL RESULT IN A
MODEST TEMPERATURE GRADIENT FRIDAY: HIGHS WILL RISE INTO THE UPPER
70S TO LOW 80S IN THE WARM SECTOR FROM THE I-10 CORRIDOR SOUTHWARD,
WITH LOW TO MID 70S OVER PARTS OF INLAND GA AND EVEN SOME UPPER 60S
POSSIBLE OVER FAR INTERIOR GA.
THE FRONT WILL BE LOCATED OVER SOUTHERN COUNTIES OF NORTHEAST FL ON
SATURDAY MORNING, CONTINUING TO NUDGE SOUTHWARD THROUGHOUT THE DAY
BEFORE DROPPING WELL SOUTH OF THE REGION SATURDAY NIGHT. CHANCES FOR
SHOWERS AND ISOLATED THUNDERSTORMS PERSIST SATURDAY MAINLY SOUTH OF
ABOUT SR 20 IN FL, THOUGH A FEW SHOWERS ARE POSSIBLE THROUGH THE
AFTERNOON HOURS AS FAR NORTH AS ABOUT I-10 OR AREAS JUST TO THE
NORTH OF I-10 DEPENDING ON THE EXACT PROGRESSION OF THE FRONT. WEAK
DRIER HIGH PRESSURE BUILDS IN FROM THE NORTH SATURDAY NIGHT WHICH
WILL RESULT IN MORE OF AN ONSHORE NORTHEASTERLY FLOW AS COMPARED TO
A NORTHWEST FLOW, AS COMPARED TO A STRONGER NORTHWEST COLD AIR
ADVECTION THAT HAS BEEN FOLLOWING FRONTAL PASSAGES THIS WINTER. AS A
RESULT, BOTH HIGH TEMPS SATURDAY AND LOW TEMPS SATURDAY NIGHT WILL
BE COOL BUT STILL FAIRLY CLOSE TO NORMAL VALUES: MID TO UPPER 70S
WILL BE EXPECTED FOR HIGHS SATURDAY EXCEPT FOR SOME MID 60S TO NEAR
70 CLOSER TO THE IMMEDIATE COAST. UPPER 50S TO LOW 50S ARE FORECAST
SATURDAY NIGHT INLAND AND OVER SOUTHEAST GA, AND MID 50S NEAR THE
ST. JOHNS RIVER BASIN AND NE FL COAST.
LONG TERM /SUNDAY THROUGH THURSDAY/
MAIN HIGHLIGHTS DURING THE PERIOD:
- CHANCES FOR COASTAL SHOWERS NEXT WEEK AND A PERSISTENT ONSHORE FLOW
WEAK HIGH PRESSURE NORTH OF THE REGION WILL BE THE MAIN SYNOPTIC
FEATURE ON SUNDAY BEFORE RIDGING GETS REINFORCED ON MONDAY AS A DRY
FRONT MOVES THROUGH THE AREA. ONSHORE FLOW AND COASTAL SHOWERS WILL
BE LIKELY FOR AT LEAST THE SUNDAY THROUGH TUESDAY TIME FRAME AS AN
INVERTED TROUGH ALSO DEVELOPS EAST OF THE FLORIDA PENINSULA. ONSHORE
FLOW LOOKS TO BREAK DOWN AROUND MID NEXT WEEK HOWEVER AS THE
INVERTED TROUGH WEAKENS AND DISSIPATES AND HIGH PRESSURE TO THE
NORTH SHIFTS MORE NORTHEAST OR EAST OF THE REGION. MORE ONSHORE FLOW
WILL KEEP COASTAL AREAS NEAR OR BELOW CLIMO FOR MOST OF THE LONG
TERM, WHILE INLAND AREAS WILL BE NEAR TO ABOVE AVERAGE OVERALL.
AVIATION /18Z THURSDAY THROUGH 18Z FRIDAY/
VFR CONDITIONS WILL BE IN PLACE THROUGH THE MAJORITY OF THE FORECAST
PERIOD. AFTERNOON S-SW WINDS WITH SPEEDS OF UP TO 10-15 KNOTS WITH
GUSTS OF UP TO ABOUT 25 KNOTS WILL DIMINISH BY THIS EVENING TO BELOW
10 KNOTS WITH CHANCES FOR SHOWERS GRADUALLY INCREASING OVER INLAND
AREAS AS CONVECTION DEVELOPS AHEAD OF AN ADVANCING FRONTAL BOUNDARY.
WINDS WILL BUILD TO ABOVE 10 KNOTS NEAR THE END OF THE FORECAST
PERIOD, BY AROUND 14Z-16Z WITH POTENTIAL IFR CEILINGS AND VICINITY
SHOWERS AFFECTING SSI BEFORE EXTENDING FURTHER SOUTH INTO THE
FORECAST AREA.
MARINE
HIGH PRESSURE CENTERED OFFSHORE OF THE SOUTHEASTERN SEABOARD WILL
CONTINUE TO EXTEND ITS AXIS WESTWARD ACROSS THE FLORIDA PENINSULA
TODAY, MAINTAINING BREEZY SOUTH-SOUTHWESTERLY WINDS TODAY FOR THE
OFFSHORE WATERS. MEANWHILE, A FRONTAL BOUNDARY STRETCHING ACROSS THE
OHIO AND TENNESSEE VALLEYS WILL PUSH INTO THE SOUTHEASTERN STATES ON
THURSDAY NIGHT. SHOWERS AND THUNDERSTORMS WILL INCREASE IN COVERAGE
ACROSS OUR LOCAL WATERS FROM LATE THURSDAY NIGHT THROUGH SATURDAY AS
THE FRONT SLOWLY MOVES ACROSS OUR AREA. ACTIVITY WILL THEN EXIT THE
NORTHEAST FLORIDA WATERS ON SATURDAY NIGHT AS THE FRONTAL BOUNDARY
SHIFTS SOUTHWARD OVER THE FLORIDA PENINSULA. HIGH PRESSURE BUILDING
OVER THE SOUTHEASTERN STATES IN THE WAKE OF THIS FRONTAL PASSAGE
WILL CREATE A PREVAILING NORTH-NORTHEASTERLY WIND FLOW THIS WEEKEND.
AN EXTENDED PERIOD OF BREEZY ONSHORE WINDS ARE THEN EXPECTED NEXT
WEEK AS A SERIES OF STRONG HIGH PRESSURE CENTERS MIGRATE EASTWARD
ACROSS NEW ENGLAND THE OFFSHORE OF THE U.S. EASTERN SEABOARD, WITH
THESE FEATURES WEDGING DOWN THE SOUTHEASTERN SEABOARD. COASTAL
TROUGHING DEVELOPING OVER OUR LOCAL WATERS EARLY NEXT WEEK WILL
GENERATE ROUNDS OF SCATTERED SHOWERS AND POSSIBLY A FEW EMBEDDED
THUNDERSTORMS.
RIP CURRENTS: A LONG PERIOD EAST-NORTHEASTERLY OCEAN SWELL WILL
PERSIST TODAY BEFORE FADING OVERNIGHT, KEEPING A MODERATE RISK IN
PLACE AT ALL AREA BEACHES. A LOW RISK IS THEN EXPECTED ON FRIDAY AND
SATURDAY DUE TO LIGHT WINDS AND LOWER SWELL PERIODS, WITH A MODERATE
RISK RETURNING BY SUNDAY AND MONDAY DUE TO GRADUALLY STRENGTHENING
ONSHORE WINDS THAT WILL CONTINUE THROUGH ALL OF NEXT WEEK.
FIRE WEATHER
- AREAS OF HIGH DISPERSIONS TODAY
- AREAS OF LOW DISPERSIONS OVER SOUTHEAST GA FRIDAY
- AREAS OF LOW DISPERSIONS AREA WIDE SATURDAY
MORE MOIST SOUTHWESTERLY FLOW CONTINUES TODAY AND THROUGH FRIDAY
MORNING AHEAD OF AN APPROACHING FRONT. THIS FRONT WILL MOVE THROUGH
FRIDAY NIGHT AND SATURDAY, BRINGING MUCH NEEDED RAINFALL TO THE
AREA. ISOLATED THUNDERSTORMS WILL ALSO BE POSSIBLE AS THE FRONT
MOVES THROUGH, PRIMARILY FRIDAY AFTERNOON THROUGH FRIDAY NIGHT NORTH
OF ABOUT I-10 AND FRIDAY NIGHT THROUGH SATURDAY AFTERNOON SOUTH OF I-
10. AREAS OF HIGH DISPERSIONS WILL BE FOUND AREA WIDE TODAY AND OVER
NORTHEAST FL ON FRIDAY, WHICH WILL QUICKLY DROP AS WEAK RIDGING
BUILDS BEHIND THE FRONT FRIDAY NIGHT AND SATURDAY AND SHIFTS THE
FLOW MORE NORTHEAST TO EASTERLY. ONSHORE FLOW IS LIKELY TO CONTINUE
INTO EARLY NEXT WEEK, WITH CHANCES FOR SHOWERS CLOSER TO THE COASTS.
FOG POTENTIAL AND OTHER REMARKS: SIGNIFICANT FOG IS NOT EXPECTED
OVER THE NEXT SEVERAL MORNINGS, THOUGH PATCHY FOG IS POSSIBLE CLOSER
TO THE I-75 CORRIDOR FRIDAY MORNING. THUNDERSTORMS ARE IN THE
FORECAST FOR LATE TONIGHT THROUGH SATURDAY, AND A FEW STRONG STORMS
WILL BE POSSIBLE, WITH THE GREATEST CHANCE OVER SE GA ON FRIDAY.
