.NEAR TERM /THROUGH SUNDAY/...
THE COLD FRONT IS CROSSING SOUTH FLORIDA...WITH HIGH PRESSURE
BEGINNING TO BUILD IN FROM THE NORTH. SKIES ARE CLEARING ACROSS
MOST AREAS...WITH SOME RESIDUAL CIRRUS SOUTH AND EAST OF JAX
EARLY IN THE OVERNIGHT. HIGH PRESSURE WILL GENERALLY PREVAIL
THROUGH THE WEEKEND...WITH A VERY WEAK SURFACE TROUGH CLIPPING
THE AREA LATE TODAY INTO THIS EVENING. WITH LAYER MOISTURE
VERY LIMITED...SOME CIRRUS CLOUDS MAY RESULT...BUT MOSTLY CLEAR
SKIES WILL PREVAIL. STRONG COLD ADVECTION IN N/NW SURFACE FLOW WILL
RESULT IN HIGHS TODAY ONLY RISING INTO THE LOWER/MID 60S. WITH WINDS
IN THE 10-15 MPH RANGE...A RATHER COOL DAY FOR LATE MARCH IS IN
THE OFFING. WINDS WILL DECREASE TNGT...ALLOWING FOR EFFECTIVE
RADIATIONAL COOLING...WITH LOWS IN THE MID/UPPER 30S FOR INLAND
LOCATIONS...WITH MAINLY 40S CLOSE TO THE COAST. WITH SOME LOW LEVEL
MOISTURE...WILL INCLUDE PATCHY FROST INLAND LATE TNGT/EARLY SUNDAY.

MILDER THAN SATURDAY INLAND...AND ACTUALLY A BIT COOLER CLOSER TO
THE COAST AS WINDS TURN ONSHORE.

.SHORT TERM /SUNDAY NIGHT THROUGH TUESDAY/...
HIGH PRESSURE RIDGE WILL SINK SOUTH ACROSS THE REGION SUNDAY NIGHT
THROUGH MONDAY. THIS WILL ALLOW A WEAK FRONTAL BOUNDARY TO SLIDE
INTO SOUTHEAST GEORGIA MONDAY AFTERNOON. THIS BOUNDARY WILL THEN
MOVE TO THE SOUTH TUESDAY. MOISTURE IS FAIRLY LIMITED WITH THIS
FRONT SO KEEPING PRECIPITATION POTENTIAL TO LOW END CHANCE.
TEMPERATURES WILL MODERATE TO NEAR NORMAL ON MONDAY...THEN SLIGHTLY
COOLER TUESDAY BEHIND THE FRONT.

.LONG TERM /TUESDAY NIGHT THROUGH FRIDAY/...
A FAIRLY PERSISTENT PATTERN IS EXPECTED WITH A HIGH PRESSURE
RIDGE CENTERED EAST OF THE REGION. THIS WILL RESULT IN A EXTENDED
PERIOD OF FLOW RANGING FROM SOUTHWEST/SOUTH/SOUTHEAST WITH WARM
ADVECTION. A SERIES OF 500MB DISTURBANCES WILL MOVE EAST ACROSS
THE AREA THIS UPCOMING WEEK WHICH WILL RESULT PERIODS WITH
UNSETTLED WEATHER. WHILE MUCH OF THE PERIOD WILL BE DRY...WILL NOT
BE ABLE TO COMPLETELY RULE OUT SHOWERS AT ANY POINT. TEMPERATURES
ARE EXPECTED TO BE ABOVE SEASONAL AVERAGES.
