Area forecast discussion, Mar 25, 4:36 AM EDT, 37 minutes before
AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHARLESTON SC
436 AM EDT TUE MAR 25 2008
.SYNOPSIS...
HIGH PRESSURE WILL PERSIST ACROSS THE REGION THROUGH FRIDAY. A WEAK
COLD FRONT WILL APPROACH FROM THE NORTHWEST ON SATURDAY...THEN
DISSIPATE ACROSS THE AREA SATURDAY NIGHT INTO EARLY SUNDAY. HIGH
PRESSURE WILL BUILD IN FROM THE NORTH LATE SUNDAY INTO MONDAY.
&&
.NEAR TERM /UNTIL 6 PM THIS EVENING/...
THE CENTER OF HIGH PRESSURE IS CURRENTLY LOCATED OVER ALABAMA AND
IS STEADILY PUSHING EASTWARD THIS MORNING. TIGHTENED PRESSURE
GRADIENT REMAINS OVER THE FORECAST AREA...PREVENTING WINDS FROM
COMPLETELY DECOUPLING AT THIS TIME. TEMPERATURES HAVE BEEN SLOWLY
DROPPING THROUGH THE EARLY MORNING HOURS...WITH MOST LOCATIONS IN
THE UPPER 30S TO LOWER 40S. FREEZE POTENTIAL WILL BE CLOSELY DEPENDENT
ON THE SPEED WITH WHICH THE HIGH PRESSURE CENTER PUSHES TOWARD
SOUTH CAROLINA AND GEORGIA...ALLOWING THE PRESSURE GRADIENT TO
RELAX AND WINDS TO LIGHTEN OVER THE AREA. CONTINUE TO FEEL THIS
WILL OCCUR A FEW HOURS BEFORE DAYBREAK. THUS FREEZING TEMPERATURES
WILL LIKELY BE REACHED INLAND...WITH SCATTERED FROST DEVELOPMENT
ALSO LIKELY ACROSS SOME LOCATIONS A BIT CLOSER TO THE COAST.
ONGOING FREEZE WARNING AND FROST ADVISORIES WILL BE UNCHANGED WITH
THE MORNING PACKAGE.
HIGH PRESSURE WILL DRIFT SOUTHEAST AND OFFSHORE THROUGHOUT THE
DAY. NORTHEAST WINDS THIS MORNING WILL VEER TO SOUTHEAST BY LATE
AFTERNOON. EXPECT ANOTHER DRY AND COOL DAY...WITH TEMPERATURES
REACHING THE LOWER TO MID 60S AWAY FROM THE COAST UNDER FULL
SUNSHINE.
&&
.SHORT TERM /6 PM THIS EVENING THROUGH 6 AM WEDNESDAY/...
WINDS WILL BE ABLE TO DECOUPLE TONIGHT...WITH THE CENTER OF HIGH
PRESSURE DIRECTLY OVER THE FORECAST AREA. SOUTHERLY FLOW WILL
PREVENT TEMPERATURES FROM REACHING FREEZING LEVELS...HOWEVER THE
CLEAR SKIES AND LIGHT WINDS WILL ENHANCE FROST POTENTIAL AWAY FROM
THE COAST. LOW LEVEL MOISTURE IS BORDERLINE...BUT FEEL THAT FAR
WESTERN COUNTIES STILL HAVE POTENTIAL TO SEE SOME SCATTERED FROST.
HAVE THUS ISSUED A FROST ADVISORY FROM JENKINS COUNTY NORTHEAST
THROUGH DORCHESTER COUNTY FROM 09Z TO 13Z. LOW TEMPERATURES WILL
RANGE FROM THE MID TO UPPER 30S INLAND TO AROUND 40 DEGREE CLOSER
TO THE COAST.
&&
.LONG TERM /WEDNESDAY THROUGH MONDAY/...
HIGH PRESSURE WILL PERSIST OVER THE REGION FROM THE WESTERN ATLANTIC
WEDNESDAY THROUGH FRIDAY...WITH RAIN FREE CONDITIONS AND WARMING
TEMPERATURES. A WEAK COLD FRONT WILL APPROACH FROM THE NORTHWEST ON
SATURDAY. THE FORECAST WILL CONTINUE TO INDICATE ONLY A SLIGHT
CHANCE OF SHOWERS AHEAD OF THE FRONT WITH DEEP MOISTURE LACKING DUE
TO A WESTERLY FLOW ALOFT. THERE APPEARS TO BE ENOUGH INSTABILITY IN
PLACE TO ADD MENTION OF ISOLATED THUNDERSTORMS...AS HIGH
TEMPERATURES ARE EXPECTED TO BE AROUND 80 IN MOST PLACES AWAY FROM
THE IMMEDIATE COAST. THE FRONT APPEARS TO STALL ACROSS THE FORECAST
AREA SATURDAY NIGHT INTO EARLY SUNDAY AS IT BECOMES PARALLEL TO THE
UPPER LEVEL FLOW...AND SHOULD EVENTUALLY DISSIPATE. WILL NEED TO
MAINTAIN A SLIGHT CHANCE OF SHOWERS IN THE FORECAST AS A RESULT.
THERE COULD BE A SIGNIFICANT GRADIENT IN HIGH TEMPERATURES FROM
NORTH TO SOUTH ON SUNDAY DEPENDING ON WHERE THE FRONT
STALLS/DISSIPATES. A MOIST RETURN FLOW AROUND HIGH PRESSURE MOVING
OFF THE NEW ENGLAND COAST ON MONDAY WILL KEEP THE POTENTIAL FOR A
FEW SHOWERS IN PLACE.
&&
.AVIATION /07Z TUESDAY THROUGH SATURDAY/...
VFR CONDITIONS WILL PREVAIL AT BOTH KCHS AND KSAV TERMINALS.
HIGH PRESSURE OVER THE SOUTHEAST STATES WILL MOVE OFFSHORE THIS
AFTERNOON...ALLOWING NORTH-NORTHEAST WINDS TO GRADUALLY VEER TO
THE SOUTH.
EXTENDED AVIATION OUTLOOK...VFR CONDITIONS EXPECTED THROUGH THE
WEEK.
&&
.MARINE...
LATEST BUOY OBSERVATIONS CONTINUE TO INDICATE SMALL CRAFT ADVISORY
WINDS THIS HOUR WITHIN A TIGHTENED PRESSURE GRADIENT AND COLD
ADVECTION REGIME. EXTENDED THE SCA FOR THE NEARSHORE WATERS UNTIL
9 AM...WHEN HIGH PRESSURE WILL HAVE MOVED CLOSER TO THE FORECAST
AREA AND RELAXED THE GRADIENT. DOWNTOWN CHARLESTON AND FOLLY BEACH
REPORTS HAVE DIMINISHED INTO THE 10 TO 15 KT RANGE...SO HAVE
CANCELED THE SCA FOR CHARLESTON HARBOR. ADVISORY FOR THE OFFSHORE
GEORGIA ZONE CONTINUES TO LOOK ON TRACK THROUGH THE MORNING...WITH
ELEVATED TOWERS REPORTING GUSTS AROUND 30 KT.
AS HIGH PRESSURE MOVES TOWARD THE GEORGIA/SOUTH CAROLINA
COASTLINE...AND THEN OFFSHORE...NORTHEAST WINDS THIS MORNING WILL
EVENTUALLY VEER TO THE EAST-SOUTHEAST LATER IN THE AFTERNOON.
SPEEDS WILL DIMINISH AS THE PRESSURE GRADIENT RELAXES.
HIGH PRESSURE OVER THE WESTERN ATLANTIC WILL KEEP SOUTH-SOUTHWEST
WINDS IN PLACE ACROSS THE COASTAL WATERS DURING THE WEDNESDAY
THROUGH SATURDAY TIME PERIOD...WITH WIND SPEEDS GENERALLY 15 KT OR
LESS. THERE COULD BE SOME LOCAL ENHANCEMENTS OF THE WIND NEAR SHORE
AND IN THE CHARLESTON HARBOR EACH AFTERNOON DUE TO THE INFLUENCE OF
THE SEA BREEZE.
&&
.FIRE WEATHER...
FIRE DANGER WILL REMAIN ELEVATED TODAY DUE TO CRITICALLY LOW
RELATIVE HUMIDITY VALUES. MODEL SOUNDINGS INDICATE THAT DEEP MIXING
LAYERS WILL ALLOW DRIER AIR ALOFT TO MIX TO THE SURFACE...WITH
MINIMUM RELATIVE HUMIDITY VALUES EXPECTED TO RANGE FROM 18-25
PERCENT AWAY FROM THE IMMEDIATE COAST. FORTUNATELY WITH HIGH
PRESSURE SHIFTING ACROSS THE AREA DURING THE DAY...WIND SPEEDS
SHOULD BE RELATIVELY LIGHT /UNDER 10 MPH/ OUTSIDE OF THE INFLUENCE
OF THE SEA BREEZE. ALTHOUGH WIND SPEEDS SHOULD NOT BE AN
