AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHARLESTON SC
348 AM EST TUE MAR 6 2007
.SHORT TERM /TODAY THROUGH THURSDAY NIGHT/...WEAK SFC COLD FRONT/
TROUGH STRETCHING ACROSS NC WILL CONTINUE TO SLIDE SWD AND INTO OUR
CWA THIS MORNING BEFORE BASICALLY WASHING OUT OVER THE AREA. THE
PRESSURE GRADIENT ASSOCIATED WITH THIS FEATURE IS HELPING KEEP
WINDS...AND TEMPS...UP A BIT...MAINLY ACROSS OUR NRN ZONES.
HOWEVER...DO NOT PLAN ON ANY CHANGES TO THE ONGOING FREEZE WARNING
AND FROST ADVISORY. A COOL DRY AREA OF HIGH PRES WILL BUILD INTO THE
AREA FROM THE NW BEHIND THE FRONT TODAY KEEPING TEMPS BELOW
NORMAL...RANGING FROM THE LOWER 60S ACROSS THE N TO UPPER 60S ACROSS
THE S. HIGH PRES TO OUR N THEN SHIFTS OFFSHORE TONIGHT WITH RIDGING
EXTENDING SWWD INTO OUR CWA. WILL LIKELY EVEN SEE WEAK COASTAL
TROUGHING DEVELOP AS LAND AREAS COOL UNDER MOSTLY CLEAR
SKIES...ALLOWING WINDS TO BACK SLIGHTLY INLAND. WITH DECENT
RADIATIONAL COOLING SETTING UP...THINK TEMPS IN THE MID 30S INLAND
LOOK REASONABLE AND WITH INCREASING LOW-LEVEL MOISTURE DUE TO A
LIGHT ONSHORE FLOW...WILL HAVE TO DEAL WITH FROST. THUS...WILL RAISE
A FROST ADVISORY FOR LATE TONIGHT FOR OUR NW TIER COUNTIES INCLUDING
INLAND JASPER COUNTY IN SC FOR AT LEAST SCATTERED FROST. ALTHOUGH A
FEW ISOLATED LOCALES MAY SEE TEMPS NEAR FREEZING ACROSS
ALLENDALE...JENKINS AND SCREVEN COUNTIES...DO NOT SEE A NEED TO
RAISE A FREEZE WATCH/WARNING ATTM.
A CLIPPER SYSTEM WILL MOVE THROUGH THE MID-ATLC REGION
TOMORROW...THEN SCOOT OFFSHORE TOMORROW NIGHT. A MILDER S/SW FLOW
ACROSS OUR AREA WILL RESULT IN A WARMER DAY THAN TODAY WITH HIGHS
REACHING THE LOWER 70S AWAY FROM THE COAST. ANOTHER WEAK SFC
TROUGH/COLD FRONT WILL APPROACH FROM THE N LATE TOMORROW NIGHT W/O
MUCH FANFARE. LOWS WILL GENERALLY BE IN THE MID 40S AWAY FROM THE
COAST.
HIGH PRES THEN BUILDS BACK INTO THE AREA THU WHILE A WEAK UPPER
SYSTEM APPROACHES FROM THE W. A DRY ATMOS PRECLUDES ANYTHING MORE
THAN A FEW MORE CLOUDS. TEMPS WILL RANGE FROM THE UPPER 60S N TO
LOWER 70S S. LOWS THU NIGHT WILL BE IN THE MID/UPPER 40S UNDER
PARTLY CLOUDY SKIES.
&&
.LONG TERM /FRIDAY THROUGH MONDAY/...NO CHANGES.
&&
.FIRE WEATHER...CRITICAL RH/S WILL CONTINUE THIS AFTN AWAY FROM THE
COAST AS VERY DRY AIR MIXES DOWN TO THE SFC DURING THE DAY. SLIGHTLY
STRONGER SFC WINDS OF 10-15 MPH ARE EXPECTED...BUT THERE ARE NO RED
FLAG CONCERNS. RH/S WILL APPROACH CRITICAL LEVELS TOMORROW AFTN WELL
INLAND BUT AGAIN THERE ARE NO RED FLAG CONCERNS.
&&
.MARINE...SFC TROUGH WILL PASS OVER THE WATERS THIS MORNING
RESULTING IN A NE WIND. WINDS WILL INCREASE TO 15 TO 20 KNOTS BEHIND
THE BOUNDARY BUT WILL BE BELOW ADVISORY CRITERIA. HIGH PRESSURE WILL
BUILD IN THROUGH WEDNESDAY AS ANOTHER SYSTEM TO THE NW WITH A
TRAILING DRY COLD FRONT APPROACHES THE COASTAL WATERS FOR WEDNESDAY
NIGHT. WINDS WILL BECOME SOUTHERLY OUT AHEAD OF THIS FEATURE AND
WILL DECREASE TO 10 TO 15 KNOTS. RECENT BUOY REPORTS SEAS 1 TO 3
FEET IN OFFSHORE FLOW BUT WILL BUILD TO 2 TO 4 FT BY EARLY AFTERNOON
AS WINDS VEER AND BECOME MORE ONSHORE. WITH A NE FETCH IN PLACE SEAS
WILL BUILD AS HIGH AS 8 FEET BY THURSDAY NIGHT AS WIND SPEEDS
INCREASE. THIS IS IN LINE WITH THE LATEST WAVE WATCH GUIDANCE.
&&
.AVIATION /09Z-06Z/...SW WINDS WILL SOON VEER TOWARD THE N AND E
BEHIND THE PASSAGE OF THE SFC TROUGH. KEPT MENTION OF LOW LEVEL WIND
SHEAR AS WINDS HAVE ALREADY DECOUPLED AT KSAV BUT HAVE BEEN
REMAINING AROUND 6 KTS AT KCHS. THE VAD WIND PROFILE AND MODEL
SOUNDINGS SHOW IT TO BE MARGINAL AT BOTH TERMINALS.
