AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHARLESTON SC
336 PM EST SUN NOV 10 2013

.SYNOPSIS...
HIGH PRESSURE WILL BUILD IN TONIGHT AND PREVAIL INTO TUESDAY. AN
ARCTIC COLD FRONT WILL SWEEP THROUGH THE REGION TUESDAY NIGHT
FOLLOWED BY STRONG HIGH PRESSURE FOR THE REST OF THE WEEK. HIGH
PRESSURE WILL BEGIN TO SHIFT EAST AND MOISTURE WILL ARRIVE FROM
THE SOUTHWEST NEXT WEEKEND.

&&

.NEAR TERM /UNTIL 6 AM MONDAY MORNING/...
TONIGHT...THE PATTERN ALOFT WILL CONTINUE TO BE NEARLY ZONAL AND
TURNING A BIT MORE CYCLONIC WITH TIME. AT THE SURFACE...A COLD FRONT
ASSOCIATED WITH A WEAK SURFACE LOW MOVING ACROSS NEW ENGLAND WILL
PUSH THROUGH AND OFFSHORE THROUGH THE OVERNIGHT. DISTINCT MID/UPPER
LEVEL DRYING IS NOTED IN MODEL TIME HEIGHTS AND SOUNDINGS...SO WE
ARE EXPECTED TO LOSE THE CLOUDS THAT HAVE HUNG AROUND IN THE 15-25
KFT RANGE TODAY. BY LATE TONIGHT SKIES ARE EXPECTED TO BE CLEAR AS A
REINFORCING AREA OF HIGH PRESSURE BUILDS IN JUST NORTH OF THE
REGION. AS THE HIGH PUSHES IN LATE...LOW LEVEL FLOW WILL TURN MORE
TO THE NE AND PICK UP ACROSS THE AREA. THIS INCREASED MIXING WILL
PREVENT RADIATIONAL COOLING FROM BECOMING TOO STRONG AND KEEP LOWS
FROM FALLING TOO LOW. LOOK FOR LOWS IN THE LOW 40S INLAND...AND
UPPER 40S TO LOW 50S ALONG THE COAST.

LAKE WINDS...AS HIGH PRESSURE BUILDS IN FROM THE NORTH TONIGHT WINDS
WILL STRENGTHEN ACROSS LAKE MOULTRIE. WINDS WILL BE IN THE 15-20 KT
RANGE WITH THE INITIAL INCREASE IN FLOW...BUT ARE NOT EXPECTED TO BE
SUPPORTIVE OF A LAKE WIND ADVISORY. THE EVENING SHIFT MAY NEED TO
REEVALUATE WHEN NEW MODEL DATA BECOME AVAILABLE.

&&

.SHORT TERM /6 AM MONDAY MORNING THROUGH WEDNESDAY/...
DRY HIGH PRESSURE WILL PREVAIL MONDAY THROUGH TUESDAY. MONDAY/MONDAY
NIGHT...SOME MARINE LOW CLOUDS COULD PUSH ONSHORE INTO
COASTAL/SOUTHERN COUNTIES. ALSO...HIGH CLOUDS WITHIN THE SUBTROPICAL
JET WILL SPREAD ACROSS THE REGION FROM THE SOUTHWEST ESPECIALLY
MONDAY AFTERNOON INTO TUESDAY. HIGH TEMPS MONDAY SHOULD RANGING FROM
68 TO 73...THEN TEMPERATURES COULD TOP OUT A DEGREE OR TWO HIGHER
TUESDAY AHEAD OF AN APPROACHING COLD FRONT.

TUESDAY NIGHT BEGINS A PERIOD OF MUCH-BELOW TEMPERATURES FOR
MID-NOVEMBER. A POWERFUL UPPER TROUGH DIGGING INTO THE SOUTHEAST
UNITED STATES AND A STRONG SURFACE HIGH PRESSURE MIGRATING SOUTHEAST
TOWARD THE MID MS RIVER VALLEY WILL DRIVE AN ARCTIC COLD FRONT
THROUGH THE FORECAST AREA TUESDAY NIGHT. SHARPLY COLDER AIR WILL
SURGE INTO THE REGION...DRIVEN BY STRONG NORTH WINDS. MODELS DIFFER
SOMEWHAT REGARDING THE INITIAL TIMING/MAGNITUDE OF COLD
ADVECTION...AND THE COLDEST GUIDANCE INCLUDING THE 10/12Z GFS DEPICT
TEMPERATURES NEAR FREEZING INLAND BY DAYBREAK WEDNESDAY. THE SUNDAY
AFTERNOON FORECAST WILL REPRESENT A COMPROMISE...WITH TEMPERATURES
BY EARLY WEDNESDAY RANGING FROM THE MID 30S INLAND TO THE LOWER-MID
40S COASTAL/SOUTHERN COUNTIES. WIND CHILLS IN THE 20/30S WILL BECOME
COMMON OVERNIGHT.

10/12Z GUIDANCE DEPICTS FORCING FOR ASCENT AND AN ASSOCIATED BAND OF
ENHANCED/POST-FRONTAL MOISTURE APPROACHING THE FORECAST AREA FROM
THE NORTHWEST BUT ERODING WITH TIME WEDNESDAY NIGHT. PER MODEL
SOUNDING TRENDS...MAINTAINED ONLY SLIGHT CHANCE POPS TUESDAY NIGHT
AS MOST LOCATIONS SHOULD NOT RECEIVE MEASURABLE PRECIPITATION. GIVEN
MAGNITUDE OF COLD ADVECTION AND THE POTENTIAL FOR SURFACE WET BULB
TEMPERATURES TO FALL BELOW 0C...CANNOT RULE OUT A COUPLE OF SLEET
PELLETS/WET SNOWFLAKES ACROSS INLAND SC OVERNIGHT...BUT MODEL
SOUNDINGS DEPICT MARKED DRYING IN THE -10C TO -20C LAYER SO FROZEN
PRECIPITATION APPEARS UNLIKELY.

WEDNESDAY WILL FEATURE WINDY/COLD CONDITIONS WITH HIGHS ONLY IN THE
UPPER 40S/LOWER 50S AT MOST LOCATIONS...AROUND 20F BELOW NORMAL.
GUIDANCE CONTINUES TO TREND TOWARD A MORE AGGRESSIVE OFFSHORE PUSH
OF DEEP LAYER DRY AIR...THUS LIMITED POPS TO COASTAL WATERS.

WINDS...EXPECT STRONG NORTHERLY WINDS BEHIND THE COLD FRONT TUESDAY
NIGHT INTO WEDNESDAY. WINDS COULD GUST AS HIGH AS 40 MPH ACROSS THE
REGION...INCLUDING LAKE MOULTRIE...AND A WIND ADVISORY OR A LAKE
WIND ADVISORY COULD EVENTUALLY BE REQUIRED.

&&

.LONG TERM /WEDNESDAY NIGHT THROUGH SUNDAY/...
WEDNESDAY NIGHT LOOKS TO BE THE COLDEST OF THE SEASON AS THE STRONG
COLD ADVECTION CONTINUES WITH THE ARCTIC HIGH BUILDING IN FROM THE
NW. OVERNIGHT LOWS WILL BE IN THE UPPER 20S TO LOWER 30S WITH A
SOLID FREEZE EXPECTED IN MANY AREAS.

THURSDAY THROUGH SATURDAY WE SHOULD SEE A GRADUAL WARMING TREND AS
THE HIGH SLOWLY MODIFIES AS IT SHIFTS NORTHEAST. HOWEVER THE HIGH
WILL PROBABLY MOVE TO A POSITION OFF THE MID-ATLANTIC OVER THE
WEEKEND THAT WILL KEEP A COOL WEDGE IN PLACE EAST OF THE
APPALACHIANS. A DEEP UPPER TROUGH BEGINS TO TAKE SHAPE TO THE WEST
WITH INCREASING MOISTURE AND POSSIBLY A STORM SYSTEM MOVING UP THE
EAST COAST SATURDAY AND SUNDAY. MAINTAINED SLIGHT CHANCE POPS
SATURDAY NIGHT AND SUNDAY.

&&

.AVIATION /21Z SUNDAY THROUGH FRIDAY/...
VFR THROUGH 18Z MON. HIGH CLOUDS WILL DECREASE OVERNIGHT AND WINDS
WILL TURN MORE TO THE NE AND PICK UP AROUND DAYBREAK.

EXTENDED AVIATION OUTLOOK...GUSTY NORTHERLY SURFACE WINDS LIKELY
TUE NIGHT AND WED AS MUCH COLDER AIR MOVES INTO THE REGION.
OTHERWISE...VFR.

&&

.MARINE...
TONIGHT...CONDITIONS WILL START OFF RATHER QUIET BEFORE HIGH
PRESSURE BUILDS IN FROM THE NORTH BEHIND A DEPARTING COLD FRONT LATE
TONIGHT. AS THE HIGH BUILDS IN...A STRONG NE PRESSURE GRADIENT AND
ATTENDING LOW LEVEL SURGE IS EXPECTED STARTING AROUND MIDNIGHT.
MODELS ARE A BIT MIXED ON THE STRENGTH OF THE SURGE...BUT THE
PREFERRED HIGHER RESOLUTION GUIDANCE IS ON THE STRONGER SIDE. AS
SUCH...WINDS WILL INCREASE ACROSS THE CHARLESTON COUNTY WATERS LATE
TONIGHT WITH FREQUENT GUSTS TO 25 KT AND A SMALL CRAFT ADVISORY HAS
BEEN HOISTED THERE. I HAVE NOT ADDED HEADLINES TO THE OTHER ZONES AS
THEY WILL PRIMARILY BE IN THE 15-20 KT RANGE. THE THREAT PERIOD FOR
SMALL CRAFT CONDITIONS WILL BE RELATIVELY SHORT AND THE ADVISORY
RUNS FROM 05Z-12Z. SEAS WILL BE ON THE INCREASE WITH THE SURGE...AND
WILL BECOME 3-5 FT FOR THE CHARLESTON COUNTY WATERS AND THE OUTER GA
WATERS. EXPECT 3-4 FT ELSEWHERE.

WINDS WILL DIMINISH AND SEAS WILL SUBSIDE AS THE DAY PROGRESSES
MONDAY...AND WINDS/SEAS WILL THEN REMAIN BELOW SCA LEVELS THROUGH
TUESDAY.

TUESDAY NIGHT...HAZARDOUS MARINE CONDITIONS WILL RAPIDLY DEVELOP AS
AN ARCTIC COLD FRONT SURGES THROUGH THE WATERS...AND HAZARDOUS
WIND/SEA CONDITIONS WILL PREVAIL WEDNESDAY AND WEDNESDAY NIGHT.
AS STRONG HIGH PRESSURE BUILDS OVER THE WATERS. AN IMPRESSIVELY
TIGHT N/NE GRADIENT WILL COMBINE WITH STRONG COLD ADVECTION/
ROBUST LOW-LEVEL MIXING OVER THE RELATIVELY WARM WATERS WILL SUPPORT
A WIDESPREAD GALE EVENT FEATURING FREQUENT GUSTS 35-40 KT MOST AREAS
AND EVEN SOME 45 KT GUSTS...JUST SHORT OF STORM FORCE...POSSIBLE
OVER THE OFFSHORE WATERS. DESPITE THE SOMEWHAT LIMITED FETCH DUE TO
THE OFFSHORE NATURE OF THE WINDS...SEAS OVER THE OUTER WATERS/BEYOND
40 NM COULD BUILD TO 15 FT WEDNESDAY...AND SEAS COULD BECOME VERY
STEEP OVER/CLOSE TO THE WEST WALL OF THE GULF STREAM. CONDITIONS
WILL GRADUALLY IMPROVE WEDNESDAY NIGHT THROUGH FRIDAY...BUT SMALL
CRAFT ADVISORY SEAS COULD PERSIST THROUGH LATE WEEK ESPECIALLY
ACROSS THE OUTER GA WATERS.

&&

.CLIMATE...
ARCTIC HIGH PRESSURE WILL DELIVER UNUSUALLY COLD AIR TO THE REGION
AROUND MIDWEEK. IF COLD AIR ARRIVES BY MIDNIGHT TUESDAY NIGHT...SOME
RECORD LOW MAXIMUM TEMPERATURE RECORDS COULD BE IN JEOPARDY
WEDNESDAY. THEN...EARLY THURSDAY MORNING TEMPERATURES COULD END UP
WITH A FEW DEGREES OF RECORD LOW FOR THE DATE. A SUMMARY OF MIDWEEK
RECORDS FOLLOWS.
