AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHARLESTON SC
704 PM EST WED JAN 4 2012

.SYNOPSIS...
A DRY COLD FRONT WILL CROSS THE REGION OVERNIGHT AND HIGH PRESSURE
WILL REMAIN TO THE SOUTH THROUGH THE END OF THE WEEK. A COLD FRONT WILL
AFFECT THE REGION LATE IN THE WEEKEND INTO EARLY NEXT WEEK FOLLOWED
BY HIGH PRESSURE THROUGH MID WEEK.

&&

.NEAR TERM /UNTIL 6 AM THURSDAY MORNING/...
WEDNESDAY EVENING...ONGOING FORECASTS REMAINED IN GOOD SHAPE AND
REQUIRED ONLY MINOR ADJUSTMENTS.

TONIGHT...A SHARP AND FAST MOVING SHORTWAVE TROF/JET MAXIMUM WILL
CROSS THE REGION FROM THE NORTHWEST. A DRY COLD FRONT...DENOTED
PRIMARILY BY A GRADUAL WIND SHIFT TO THE W...ASSOCIATED WITH THIS
MID/UPPER LEVEL FEATURE WILL ALSO CROSS THE REGION PRIMARILY AFTER
MIDNIGHT. OTHER THAN A PASSING HIGH CLOUDS THE SHORTWAVE/FRONT WILL
HAVE ONLY MINOR EFFECTS ON THE SENSIBLE WX FORECAST. THE PRESSURE
GRADIENT WILL TIGHTEN UP A BIT JUST AHEAD OF THE FRONT AND
DEVELOPING LEE SIDE TROFFING IN THE LEE OF THE SOUTHERN
APPALACHIANS...WHICH SHOULD PREVENT THE ENTIRE AREA FROM
DECOUPLING. OVERNIGHT TEMPS WILL ONCE AGAIN BE COLD...THOUGH ABOUT
10 DEGREES WARMER THAN EARLY WEDNESDAY MORNING. EXPECT UPPER 20S ACROSS
INLAND AREAS WHICH HAVE A BETTER CHANCE OF DECOUPLING...WITH LOWER
TO MID 30S CLOSER TO THE COAST.

&&

.SHORT TERM /6 AM THURSDAY MORNING THROUGH SATURDAY/...
AN UPPER TROUGH OF LOW PRESSURE WILL DEPART THE EASTERN U.S. ON
THURSDAY AND BE REPLACED BY WEAK UPPER HIGH PRESSURE FRIDAY. BY
SATURDAY...A SOUTHERN STREAM UPPER SHORTWAVE IS EXPECTED TO APPROACH
THE AREA FROM THE SOUTHWEST WHILE A SURFACE COLD FRONT APPROACHES
FROM THE NORTHWEST. LIFT AND DEEP LAYER MOISTURE APPEAR LIMITED AND
THUS WILL CONTINUE WITH LOW RAIN CHANCES.

TEMPERATURES WILL GRADUALLY MODERATE THROUGH THE PERIOD. HIGHS
SHOULD RISE ABOVE NORMAL INTO THE MID TO UPPER 60S BY FRIDAY AND
SATURDAY AS A SURFACE RIDGE OF HIGH PRESSURE SOUTH OF THE REGION
CREATES A WSW LOW LEVEL FLOW. EXPECT LOWS IN THE LOWER TO MID 30S
AWAY FROM THE BEACHES FRIDAY MORNING...THEN LOWER TO MID 40S MOST
AREAS SATURDAY MORNING.

&&

.LONG TERM /SATURDAY NIGHT THROUGH WEDNESDAY/...
A COLD FRONT LOOKS TO MOVE TOWARD THE AREA SATURDAY NIGHT...POSSIBLY
PUSHING INTO THE AREA OR REMAINING JUST NORTH OF THE AREA THROUGH
EARLY NEXT WEEK. THE FRONT WILL LIKELY HAVE A HARD TIME PUSHING
COMPLETELY THROUGH THE FORECAST AREA GIVEN THE ZONAL UPPER
FLOW...POSSIBLY WAITING UNTIL AN UPPER CUTOFF LOW SHIFTS EAST FROM
THE SOUTHERN PLAINS TOWARD MID WEEK. FOR NOW MAINTAINED PREVIOUS
FORECAST OF TEMPERATURES ABOVE NORMAL THROUGH MONDAY RETURNING TO
NEAR NORMAL THEREAFTER WITH LOW RAIN CHANCES THROUGH THE PERIOD.
LOOKS LIKE THERE COULD BE A SEVERE WEATHER THREAT NEXT WEDNESDAY
BASED ON THE 12Z/04 GFS/ECMWF SO THIS WILL BE SOMETHING TO WATCH.

&&

.AVIATION /00Z THURSDAY THROUGH MONDAY/...
VFR THROUGH EARLY THURSDAY. 00Z TAF FORECAST DETAILS HIGHLIGHT
CHANGES IN WIND DIRECTION/SPEED...S/SW LESS THAN 10 KT THIS
EVENING VEERING TOWARD THE W AT SIMILAR SPEEDS OVERNIGHT...THEN
VEERING NW WIND OCCASIONAL GUSTS TO AROUND 15 KT THURSDAY.

EXTENDED AVIATION OUTLOOK...MVFR CIGS POSSIBLE ESPECIALLY LATE IN
THE WEEKEND INTO EARLY NEXT WEEK AS A COLD FRONT APPROACHES AND
LINGERS NEAR THE AREA.

&&

.MARINE...
TONIGHT...A SHORTWAVE TROUGH ALOFT AND ASSOCIATED DRY SURFACE COLD
FRONT WILL CROSS THE LOCAL WATERS AFTER MIDNIGHT. EXPECT LOW LEVEL
WINDS TO SURGE AS THESE FEATURES PASS. SW WINDS VEERING W WILL
INCREASE TO 15-20 KT OVERNIGHT...AND WILL CONTINUE TO ASSESS THE
POTENTIAL FOR SMALL CRAFT ADVISORY GUSTS TO 25 KT ESPECIALLY
ACROSS THE NEARSHORE SC WATERS AND THE OUTER GA WATERS. SEAS WILL
BUILD IN RESPONSE TO THE INCREASING WINDS...BECOMING 2-3 FT INSIDE
OF 20 NM AND 3-5 FT BEYOND 20 NM.

THURSDAY THROUGH MONDAY...SURFACE HIGH PRESSURE WILL REMAIN SOUTH OF
THE AREA THROUGH FRIDAY BEFORE PUSHING INTO THE ATLANTIC SATURDAY
AHEAD OF AN APPROACHING COLD FRONT. LOOKS LIKE THE FRONT WILL STALL
OUT OVER OR NEAR THE AREA SUNDAY INTO MONDAY BUT THE EXACT POSITION
IS UNCERTAIN AND THUS WINDS/SEAS ARE AS WELL. HOWEVER...ADVISORIES
ARE NOT EXPECTED DURING THIS PERIOD.

&&

.CHS WATCHES/WARNINGS/ADVISORIES...
