NEAR TERM /THROUGH TONIGHT/
MORNING DENSE FOG WILL CONTINUE FROM THE LOCAL ATLANTIC COASTAL

LASTING LONGER NEAR AND EAST OF THE HIGHWAY 301 CORRIDOR THROUGH MID-
MORNING (10 AM TO 11 AM) AND FOR COASTAL COMMUNITIES THROUGH AT
LEAST MIDDAY. AS SOUTHERLY WINDS INCREASE INTO THE AFTERNOON, THE
BULK OF SEA FOG WILL POSITION NEAR TO JUST OFFSHORE, BUT AS WINDS
VEER SE NEAR THE COAST WITH THE ATLANTIC COAST SEA BREEZE INTO THE
LATE AFTERNOON, SEA FOG WILL LIKELY BEGIN TO DRIFT INLAND ONCE AGAIN
IMPACTING SOME COASTAL COMMUNITIES NEAR AND EAST OF I-95 BY THE
EARLY EVENING HOURS. FOG WILL ONCE AGAIN ADVECT INLAND TONIGHT
THROUGH EARLY SATURDAY MORNING, BUT FROM BOTH THE ATLANTIC AND GULF
COASTS. ANOTHER DENSE FOG ADVISORY WILL LIKELY BE NEEDED THROUGH
EARLY SATURDAY MORNING.
OTHER THAN FOG, ANOTHER ABOVE AVERAGE WARM DAY IS EXPECTED AS THE
MID LEVEL RIDGE AMPLIFIES OVER THE FL PENINSULA. EXPECT A MORE
ROBUST AFTERNOON LOW LEVEL CUMULUS FIELD AND POSSIBLY SOME VERY
LIGHT SPRINKLES UNDER THE THICKER BASES LATE AFTERNOON, OTHERWISE
DRY WEATHER PREVAILS. HIGH TEMPERATURES WILL RANGE FROM THE LOW 80S
WELL INLAND TO THE 70S ALONG THE COAST, ABOUT 15-20 DEG ABOVE
AVERAGE HIGHS FOR THIS TIME OF YEAR. TONIGHT, ANOTHER ROUND OF MILD,
ABOVE AVERAGE INLAND LOWS IN THE UPPER 50S TO LOW 60S.
SHORT TERM /SATURDAY THROUGH SUNDAY NIGHT/
HIGH PRESSURE RIDGE WILL CONTINUE TO MOVE AWAY TO THE EAST SATURDAY,
AS COLD FRONT APPROACHES FROM THE NORTHWEST. A FEW SHOWERS MAY
MOVING INTO INLAND SE GA LATE SATURDAY AFTERNOON, BUT A MOSTLY DRY
DAY IS EXPECTED. A MILD TO SOUTH TO SOUTHWEST FLOW WILL PUSH
TEMPERATURES WELL ABOVE AVERAGE.
FOR SATURDAY NIGHT, THE COLD FRONT WILL MOVE ACROSS. THE BEST ENERGY
WITH THIS SYSTEM MOVES OFF TO THE NORTHEAST, SO A DISSIPATING LINE
OF SHOWERS IS FORECAST WITH FRONTAL PASSAGE. TEMPERATURES WILL
REMAIN ABOVE AVERAGE SATURDAY NIGHT.
AN UPPER WAVE FOLLOWING THE FRONT, MAY PRODUCE A FEW SHOWERS DURING
THE DAY SUNDAY, BUT MUCH OF SUNDAY WILL BE DRY. AS SURFACE HIGH
PRESSURE BUILDS TO THE NORTHWEST SUNDAY, THE FLOW WILL BECOME MORE
FROM THE NORTHWEST. THIS COLD ADVECTION WILL YIELD FALLING
TEMPERATURES SUNDAY AFTERNOON, WITH A NON DIURNAL CURVE.
A LIGHT INLAND FREEZE CAN BE EXPECTED SUNDAY NIGHT. TOO MUCH WIND
DUE TO PRESSURE GRADIENT WITH BUILDING HIGH, SO NOT EXPECTING FROST
FORMATION DESPITE THE COLD READINGS.
LONG TERM /MONDAY THROUGH THURSDAY/
THE HIGH PRESSURE RIDGE WHICH WILL STRETCH JUST TO THE NORTHWEST OF
THE AREA ON MONDAY, WILL SETTLE NEARLY OVERHEAD TUESDAY. A WELL
BELOW NORMAL DAY MONDAY, AND MONDAY NIGHT IS FORECAST. AN INLAND
FREEZE IS FORECAST, WITH LIGHTER WINDS LEADING TO A FAIRLY
WIDESPREAD INLAND FROST AS WELL. TEMPERATURES WILL RECOVER TO NEAR
NORMAL TUESDAY.
A WAVE OF LOW PRESSURE WILL LIFT NORTHEAST ACROSS CENTRAL FL ON
WEDNESDAY. SCATTERED SHOWERS WITH TEMPERATURES REMAINING BELOW
AVERAGE.
ANOTHER WAVE OF LOW PRESSURE WILL MOVE EAST NORTHEAST ACROSS THE

TO EAST UNDER LIGHT SOUTHERLY WINDS < 5 KTS. SEA FOG WILL HUG NEAR
COASTAL TERMINALS INTO THE AFTERNOON WITH HIGHER CONFIDENCE OF
RESTRICTIONS IMPACTING SSI, CRG AND SGJ WHILE VFR DEVELOPS AT JAX,
VQQ AND GNV AFTER 18Z UNDER SOUTHERLY WINDS 5-10 KTS. AS WINDS
BECOME SE AT THE COAST MID TO LATE AFTERNOON, SEA FOG WILL ONCE
AGAIN DRIFT INLAND AND BRING A RETURN OF LOWERING RESTRICTIONS
EXPANDING INLAND TOWARD JAX AND VQQ THROUGH 06Z TONIGHT. SSW WINDS
DEVELOP THIS AFTERNOON AND CONTINUE OVERNIGHT AT GNV. THIS PATTERN
WILL BRING GULF COAST FOG AND STRATUS INLAND AFTER 06Z TOWARD GNV
THROUGH 12Z SATURDAY.
MARINE
HIGH PRESSURE WILL EXTEND ACROSS THE LOCAL WATERS THROUGH TONIGHT.
WIDESPREAD SEA FOG WILL CONTINUE THROUGH AT LEAST MIDDAY, WITH SOME
IMPROVEMENT NEAR THE COAST DURING THE EARLY AFTERNOON. AS THE EAST
COAST SEA BREEZE DEVELOPS LATE AFTERNOON, FOG WILL SHIFT INLAND INTO
TRIBUTARIES AND LINGER THROUGH EARLY SATURDAY MORNING.
SOUTHWEST WINDS DEVELOP SATURDAY AHEAD OF AN APPROACHING FRONT,
WHICH WILL REDUCE FOG COVERAGE BY MIDDAY. THE FRONT WILL MOVE ACROSS
THE LOCAL WATERS SATURDAY NIGHT INTO SUNDAY WITH A CHANCE OF PASSING
SHOWERS. STRONGER NORTHWEST WINDS DEVELOP SUNDAY WITH SMALL CRAFT
ADVISORY CONDITIONS THROUGH EARLY MONDAY, WITH OCCASIONAL GUSTS NEAR
GALE FORCE. WINDS AND SEAS FALL BELOW ADVISORY LEVELS LATE MONDAY
