5 AM EST SATURDAY. 

* TIMING OF GALES: THE RISK FOR GALES WILL BE THE GREATEST FROM
  THIS EVENING THROUGH EARLY SATURDAY.

* WINDS: SOUTH WINDS OF 20 TO 25 KNOTS WITH GUSTS TO 30 KNOTS WILL
  SHIFT WEST AND INCREASE TO 30 TO 35 KNOTS WITH GUSTS TO 45 KNOTS
  THIS EVENING. GALES WILL LINGER INTO EARLY SATURDAY MORNING.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

A GALE WARNING MEANS SUSTAINED WINDS OR FREQUENT GUSTS OF 34 TO
47 KNOTS ARE EXPECTED. OPERATING A VESSEL IN GALE CONDITIONS

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHARLESTON SC
1218 AM EST WED DEC 19 2012

.SYNOPSIS...
HIGH PRESSURE WILL SHIFT EASTWARD OVER THE AREA THROUGH WEDNESDAY.
A STRONG COLD FRONT WILL PUSH THROUGH THE REGION LATE THURSDAY...WITH
MUCH COOLER AND DRY WEATHER BEHIND IT THROUGH EARLY NEXT WEEK.

&&

.NEAR TERM /UNTIL 6 AM THIS MORNING/...
NEAR PERFECT RADIATIONAL CONDITIONS ARE IN PLACE THIS MORNING WITH
CALM/LIGHT WINDS AND CLEAR SKIES. TEMPERATURES ARE STILL FALLING A
LITTLE QUICKER THAN EXPECTED...ESPECIALLY INLAND...SO LOWERED LOW
TEMPERATURES ANOTHER 1-2 DEGREES FOR MANY LOCATIONS. SOME THIN
CIRRUS WILL LIKELY SPILL THROUGH THE AREA EARLY THIS MORNING...BUT
CLEAR SKIES WILL PREVAIL.

&&

.SHORT TERM /6 AM THIS MORNING THROUGH FRIDAY/...
WEDNESDAY...DRY SURFACE HIGH PRESSURE WILL STEADILY TRACK ACROSS
THE FORECAST AREA AND INTO THE ATLANTIC THROUGH WEDNESDAY
NIGHT...WHILE THE AXIS OF UPPER RIDGING SIMULTANEOUSLY SLIPS OVER
THE EAST COAST. WEST/SOUTHWEST FLOW...FULL INSOLATION...AND DEEP
LAYER RIDGING WILL SUPPORT ANOTHER SUNNY AND MILD DAY.
TEMPERATURES WILL PEAK AROUND 70 DEGREES DURING THE AFTERNOON
HOURS...NEARLY 10 DEGREES ABOVE SEASONAL NORMALS. AS A ROBUST
UPPER TROUGH AND SURFACE LOW SYSTEM RAPIDLY APPROACH FROM THE
WEST...A SUBTLE WARM FRONT WILL LIFT THROUGH THE AREA AFTER
MIDNIGHT AHEAD OF THE ASSOCIATED COLD FRONT. WINDS WILL BECOME
MORE SOUTHERLY AS A RESULT...AND CONSIDERING WARM ADVECTION AND
INCREASING LOW LEVEL MOISTURE...EXPECT WARMER MINIMUM TEMPERATURES
IN THE LOWER 40S INLAND TO NEAR 50 DEGREES ALONG THE COAST.

THURSDAY THROUGH EARLY FRIDAY...THE SOUTHEAST STATES WILL FALL
SOLIDLY WITHIN THE WARM SECTOR OF THE WELL-DEVELOPED FRONTAL
SYSTEM...STRETCHING FROM THE OHIO VALLEY THROUGH THE SOUTHERN
MISSISSIPPI VALLEY BY SUNRISE THURSDAY. DEEP LAYER SOUTH/SOUTHWEST
FLOW WILL SUPPORT ANOTHER UNSEASONABLY WARM DAY...WITH HIGH
TEMPERATURES REACHING THE MID TO UPPER 70S...WHILE ALSO ADVECTING
HIGHER DEWPOINT AIR FROM THE GULF OF MEXICO NORTHWARD. THE EXTENT
OF THIS LOW TO MID LEVEL MOISTURE ADVECTION COULD BE A FACTOR IN
CONVECTIVE DEVELOPMENT THURSDAY AFTERNOON...AND THERE REMAINS SOME
UNCERTAINTY REGARDING THE POTENTIAL FOR SEVERE WEATHER WITH THE
PASSAGE OF THIS FRONTAL SYSTEM. THERE IS DECENT AGREEMENT IN
NUMERICAL MODEL SOLUTIONS THAT INSTABILITY WILL BE QUITE MARGINAL
THURSDAY AFTERNOON...ESPECIALLY IF HIGHER DEWPOINTS FAIL TO SURGE
FAR ENOUGH NORTH INTO THE FORECAST AREA. THUS...ORGANIZED
STRONG/SEVERE THUNDERSTORM DEVELOPMENT WILL BE HEAVILY DEPENDENT
ON ROBUST DYNAMICS IN SUCH A HIGH SHEAR/LOW CAPE SCENARIO.

AN IMPRESSIVE 50 TO 60 KT LOW LEVEL JET...EVIDENT DOWN TO
925 MB...WILL PASS DIRECTLY OVER THE FORECAST AREA DURING THE
FAVORED AFTERNOON HOURS. FARTHER ALOFT...A 100 KT UPPER JET WILL
BE LOCATED JUST WEST OF THE AREA DURING THE AFTERNOON HOURS BEFORE
SLIPPING TOWARD THE COASTLINE OVERNIGHT. THE REGION APPEARS TO
FALL WITHIN THE RIGHT ENTRANCE REGION OF THE JET DURING THIS
TIME...SUPPORTIVE OF ENHANCED UPPER LEVEL FORCING FOR ASCENT. THE
COMBINED EFFECTS OF ROBUST WIND FIELDS IN THE LOW AND UPPER LEVELS
INDICATE DEEP LAYER SHEAR...SUGGESTING THAT ANY ORGANIZED
CONVECTION COULD PRODUCE STRONG TO DAMAGING WIND GUSTS. ALTHOUGH
THERE ARE STILL SOME SIGNIFICANT QUESTIONS REMAINS AS TO WHETHER
UPPER LEVEL FORCING WILL BE SUFFICIENT TO OVERCOME THE LACK OF LOW
LEVEL INSTABILITY...STORM PREDICTION CENTER MAINTAINS A DAY 3
SLIGHT RISK FOR THE AREA. WILL THUS CONTINUE TO HIGHLIGHT THE
POTENTIAL FOR SEVERE WEATHER IN THE HAZARDOUS WEATHER OUTLOOK AT
THIS TIME.

OVERALL...SHOWER/THUNDERSTORM CHANCES WILL INCREASE FROM WEST TO
EAST FROM THURSDAY MORNING THROUGH AROUND MIDNIGHT...BEFORE THE
COLD FRONT QUICKLY SHIFTS OFFSHORE EARLY FRIDAY MORNING.
CONSIDERING DECENT MODEL AGREEMENT IN PRECIPITATION
COVERAGE...HAVE MAINTAINED LIKELY WORDING IN THE FORECAST FOR
RAIN...WITH POPS PEAKING IN THE 70 PERCENT RANGE.

FRIDAY...THE UPPER TROUGH WILL CLOSE OFF BY DAYBREAK FRIDAY AS IT
LIFTS INTO THE NEW ENGLAND STATES. THE CO-LOCATED SURFACE LOW
WILL ALSO MOVE NORTHEAST AND DRAG THE TRAILING COLD FRONT INTO THE
ATLANTIC EARLY FRIDAY MORNING. DUE TO THE RAPID FRONTAL
PROGRESSION AND INTRUSION OF DEEP LAYER DRY AIR IN ITS WAKE...RAIN
CHANCES WILL BE NEAR ZERO BY SUNRISE. BREEZY AND SIGNIFICANTLY
COOLER CONDITIONS ARE EXPECTED FRIDAY...WITH HIGH TEMPERATURES
SUPPRESSED IN THE UPPER 50S ACROSS THE FORECAST AREA UNDER STRONG
COLD ADVECTION AND DESPITE SUNNY SKIES.

LAKE WINDS...EXPECT ANOTHER LAKE WIND ADVISORY FOR LAKE MOULTRIE
IN WAKE OF THE NEXT COLD FRONT LATE IN THE WEEK...AS MUCH OF THE
30-35 KT GEOSTROPHIC WINDS AT 1000 MILLIBARS MIXES DOWN WITHIN THE
COLD ADVECTION REGIME THURSDAY NIGHT INTO FRIDAY.

&&

.LONG TERM /FRIDAY NIGHT THROUGH TUESDAY/...
COOL AND DRY CONDITIONS WILL PERSIST THROUGH THE WEEKEND...AS
HIGH PRESSURE SETTLES OVER THE SOUTHEAST. OVERALL...TEMPERATURES
WILL REMAIN NEAR CLIMATOLOGICAL HIGHS UNDER A ZONAL FLOW
PATTERN...REACHING THE UPPER 50S TO AROUND 60 EACH AFTERNOON. A
GRADUAL WARMING OF 1-2 DEGREES IS THEN ANTICIPATED EARLY NEXT
WEEK...AS A TROUGH OF LOW PRESSURE DEVELOPS OVER THE SOUTH
CENTRAL UNITED STATES. A SLIGHT CHANCE OF SHOWERS IS POSSIBLE BY
TUESDAY...AS MOISTURE RETURNS OVER THE SOUTHEAST AHEAD OF THE
TROUGH TO THE WEST. OVERNIGHT TEMPERATURES WILL LIKELY REACH THE
LOW 30S AWAY FROM COAST FRIDAY...BEFORE GRADUALLY WARMING INTO THE
MID 30S TO LOW 40S BY THE BEGINNING OF NEXT WEEK.

LAKE WINDS...AN ONGOING LAKE WIND ADVISORY CAN BE ANTICIPATED
INTO AT LEAST EARLY SATURDAY WITH COLDER AIR MOVING ACROSS THE
RELATIVELY WARMER WATERS OF LAKE MOULTRIE.

&&

.AVIATION /05Z WEDNESDAY THROUGH SUNDAY/...
VFR.

EXTENDED AVIATION OUTLOOK...VFR THROUGH WEDNESDAY NIGHT...BEFORE
DETERIORATING LATE THURSDAY AS A STRONG COLD FRONT APPROACHES
FROM THE WEST. GUSTY WINDS AND PERIODS OF MVFR OR LOWER CIGS/VSBYS
ARE POSSIBLE THURSDAY EVENING THROUGH EARLY FRIDAY...WITH SHOWERS
ALONG AND AHEAD OF THE PASSING COLD FRONT. VFR CONDITIONS WILL
THEN PREVAIL FRIDAY AFTERNOON THROUGH SATURDAY.

&&

.MARINE...
TONIGHT...A MUCH MORE RELAXED PRESSURE PATTERN WILL DEVELOP AS
HIGH PRESSURE BUILDS FROM THE WEST AND SW. MARINERS CAN EXPECT
WEST OR NW WINDS AS HIGH AS 15 KT EARLY ON...DROPPING OFF ABOUT
5-10 KT AFTER MIDNIGHT. SEAS WILL BE MOSTLY COMPRISED OF
SOUTHERLY SWELLS...AVERAGING 2-3 FT WITHIN 20 NM OF SHORE AND 3-5
FT FURTHER OUT THROUGH MIDNIGHT...THEN DROPPING ANOTHER FOOT OR
SO THEREAFTER.

WEDNESDAY THROUGH SATURDAY...HIGH PRESSURE WILL BUILD OVER THE
WATERS THROUGH WEDNESDAY NIGHT...KEEPING WINDS/SEAS WELL BELOW
SMALL CRAFT ADVISORY CONDITIONS. CONDITIONS WILL THEN RAPIDLY
DETERIORATE AHEAD OF A STRONG COLD FRONT APPROACHING FROM THE
WEST THURSDAY. INCREASING WINDS AND BUILDING SEAS WILL REACH
SMALL CRAFT ADVISORY LEVELS FOR ALL MARINE ZONES BY THURSDAY
AFTERNOON...AS A TIGHTENED PRESSURE GRADIENT DEVELOPS OVER THE
WATERS ALONG AND AHEAD OF THE COLD FRONT. STRONG COLD ADVECTION
BEHIND THE FRONT...WHEN COMBINED WITH THE ENHANCED PRESSURE
GRADIENT...FAVORS SUSTAINED 30 KT WINDS WITH GUSTS BETWEEN 35-40
KT OVER THE NEARSHORE AND OFFSHORE MARINE ZONES THURSDAY NIGHT
THROUGH FRIDAY MORNING. SEAS WILL PEAK BETWEEN 6 TO 8 FT...HIGHEST
IN WATERS BEYOND 10 NM FROM THE COAST. A GALE WATCH/WARNING MAY
EVENTUALLY BE NEEDED IF TRENDS CONTINUE TO INDICATE THESE
HAZARDOUS MARINE CONDITIONS. THE PATTERN WILL SUPPORT AT LEAST
PERSISTENT SMALL ADVISORY CONDITIONS THROUGH EARLY
SATURDAY...BEFORE HIGH PRESSURE SETTLES OVER THE WATERS.

TIDES...A PROLONGED PERIOD OF STRONG OFFSHORE WINDS WILL LIKELY
LEAD TO THE DEVELOPMENT OF BLOW-OUT TIDES LATE THIS WEEK...WITH
TIDAL DEPARTURES AS MUCH AS 1.5 TO 2.0 FT MLLW BELOW PREDICTED
LEVELS.
