AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHARLESTON SC
1251 PM EST TUE FEB 22 2011

.SYNOPSIS...
A COLD FRONT WILL APPROACH THE REGION FROM THE NORTH AND WEST
TODAY...THEN PUSH SOUTH THROUGH THE REGION TONIGHT. HIGH PRES WILL
BUILD INTO THE REGION WED AND WILL REMAIN THE DOMINANT WEATHER
FEATURE OVER THE SOUTHEAST STATES THROUGH THU. THE NEXT COLD FRONT
WILL MOVE THROUGH THE REGION LATE IN THE WEEK...WITH HIGH PRES TO
FOLLOW FOR THE UPCOMING WEEKEND. ANOTHER COLD FRONT IS EXPECTED TO
MOVE THROUGH THE REGION EARLY NEXT WEEK.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
TEMPERATURES WARMING INTO THE MID TO UPPER 70S MOST LOCALES THIS
AFTERNOON DESPITE THE PARTLY TO MOSTLY CLOUDY SKIES AHEAD OF A
COLD FRONT APPROACHING FROM THE WEST AND BACKDOOR COLD FRONT
APPROACHING FROM THE NORTH. COULD SEE A FEW 80 DEGREE HIGHS. WESTERLY
WINDS WILL CONTINUE TO GUST 20-25 MPH THROUGH THE AFTERNOON.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH FRIDAY/...
A BACKDOOR COLD FRONT INTRODUCING SOME STRONG LOW LEVEL THERMAL
GRADIENTS WILL DRIVE DOWN COASTAL SOUTH CAROLINA AND SE GEORGIA
TONIGHT FROM N TO S. TEMPERATURES WILL START OFF VERY MILD AT
DUSK AND FALL AS THE FRONT PASSES THROUGH AND WINDS SHIFT TO THE
NE. BY DAWN ON WED...MOST LOCATIONS AWAY FROM THE BEACHES AND
BARRIER ISLANDS SHOULD BE IN THE UPPER 40S WITH SOME MID 40S
W AND N OF CHARLESTON. PARTLY TO MOSTLY CLOUDY CONDITIONS ARE
EXPECTED TO FILL IN THE WAKE OF THE SURFACE FRONT...BUT DRY
WEATHER WILL CONTINUE OVERNIGHT.

MODEL SOLUTIONS ARE IN GOOD AGREEMENT SHOWING HIGH PRESSURE BUILDING
NORTH OF THE NEW ENGLAND AND MID-ATLANTIC STATES WEDNESDAY...BEFORE
SHIFTING INTO THE WESTERN ATLANTIC WEDNESDAY NIGHT AND THURSDAY. A
COLD FRONT WILL APPROACH FROM THE WEST THURSDAY NIGHT...THEN MOVE
THROUGH THE LOCAL AREA ON FRIDAY.

WEDNESDAY THROUGH THURSDAY...WILL KEEP THE FORECAST RAIN FREE AS
HIGH PRESSURE REMAINS THE DOMINANT WEATHER FEATURE. CAN/T RULE OUT
A FEW ISOLATED SHOWERS GRAZING COASTAL SOUTH CAROLINA ZONES
THURSDAY AFTERNOON AS RETURN FLOW GETS ESTABLISHED ALLOWING A
COASTAL TROUGH TO LIFT NORTHWARD JUST OFFSHORE. PROBABILITIES
REMAIN TOO LOW TO MENTION IN THE FORECAST AT THIS TIME...BUT WILL
NEED TO MONITOR MODEL TRENDS CLOSELY AS A COUPLE SOLUTIONS NOW
SHOW SOME SHOWER ACTIVITY MOVING INTO COASTAL SOUTH CAROLINA ZONES
THURSDAY AFTERNOON. TEMPERATURES ON WEDNESDAY WILL BE NOTICEABLY
COOLER AS THE COLD DENSE AIRMASS CURRENTLY OVER THE MID-ATLANTIC
STATES SHIFTS SOUTHWARD INTO THE LOCAL AREA. THE LATEST MODEL
TRENDS SUGGEST THAT THE AIRMASS WILL REMAIN FAIRLY INVERTED OVER
THE LOCAL AREA...AND THIS SEEMS REASONABLE GIVEN A STRENGTHENING
COASTAL TROUGH OFFSHORE. FOR NOW WILL LOOK FOR HIGHS WEDNESDAY
TOPPING OUT AROUND 60 NORTH TO THE LOWER/MIDDLE 60S SOUTH. LOWS
WEDNESDAY NIGHT ARE EXPECTED TO BOTTOM OUT AROUND 40/LOWER 40S
NORTH TO THE MIDDLE/UPPER 40S SOUTH. HIGHS ON THURSDAY WILL BE
HIGHLY DEPENDENT ON HOW QUICKLY THE HIGH PRESSURE WEDGE IS ABLE TO
BREAK DOWN ALLOWING RETURN FLOW TO GET ESTABLISHED. GIVEN THE
INCREASING WARM AIR ADVECTION ACROSS THE REGION...THERE SHOULD BE
ENOUGH CLOUD COVER TO KEEP TEMPERATURES FROM GETTING OUT OF
HAND...AND WILL LOOK FOR HIGHS IN THE UPPER 60S NORTH TO LOWER 70S
SOUTH.

THURSDAY NIGHT AND FRIDAY...
A COLD FRONT WILL APPROACH FROM THE WEST ON THURSDAY THEN MOVE
THROUGH THE REGION ON FRIDAY. RAIN FREE CONDITIONS ARE EXPECTED
THURSDAY NIGHT...ALTHOUGH WE CAN/T ENTIRELY RULE OUT A FEW ISOLATED
SHOWERS ALONG SOUTH CAROLINA COAST EARLY THURSDAY EVENING AS THE
COASTAL TROUGH LIFTS NORTHWARD JUST OFFSHORE. DEEP MOISTURE AND
FORCING FOR ASCENT WILL INCREASE FROM WEST TO EAST ACROSS THE AREA
ON FRIDAY...AND WILL CARRY SLIGHT CHANCE/LOW CHANCE POPS THROUGH THE
DAY. TEMPERATURES THURSDAY NIGHT ARE NOT EXPECTED TO DROP TOO
MUCH...GENERALLY BOTTOMING OUT IN THE MID TO UPPER 50S. WITH LOW
LEVEL WIND FIELDS INCREASING LATE THURSDAY NIGHT...TEMPERATURES WILL
LIKELY RESPOND AND CLIMB INTO THE MIDDLE 60S BY DAYBREAK FRIDAY.
TEMPERATURES ON FRIDAY WILL BE DIFFICULT TO PIN DOWN AS THEY WILL BE
HIGHLY DEPENDENT ON THE TIMING OF THE COLD FRONT THROUGH THE AREA.
LOW LEVEL THICKNESS VALUES SUPPORT HIGHS IN THE LOWER 80S...BUT WITH
PLENTY OF CLOUD COVER AND SCATTERED SHOWERS ACROSS THE REGION...WILL
LOOK FOR HIGHS GENERALLY TOPPING OUT IN THE MIDDLE 70S.

&&

.LONG TERM /FRIDAY NIGHT THROUGH MONDAY/...
MEDIUM RANGE GUIDANCE IS IN GOOD AGREEMENT WITH THE OVERALL SYNOPTIC
PATTERN EVOLUTION THROUGH THE EXTENDED PERIODS...BUT SUBTLE
DISAGREEMENTS WITH RESPECT TO PLACEMENT OF SYNOPTIC FEATURES WILL
LEAD TO SLIGHTLY BELOW NORMAL FORECAST CONFIDENCE.

HIGH PRESSURE WILL BUILD BACK INTO THE REGION BEHIND THE DEPARTING
COLD FRONT FRIDAY NIGHT AND WILL REMAIN THE THE DOMINANT WEATHER
FEATURE THROUGH SUNDAY. MODEL SOLUTIONS DISAGREE ON THE STRENGTH OF
AN AREA OF HIGH PRESSURE BUILDING ACROSS THE OHIO VALLEY AND
MID-ATLANTIC STATES ON SUNDAY...AND THIS HAS REPERCUSSIONS ON THE
PLACEMENT OF A FRONTAL BOUNDARY THROUGH THE SOUTHERN MID-ATLANTIC
STATES OR NORTHERN SECTIONS OF THE SOUTHEAST UNITED STATES SUNDAY
NIGHT INTO MONDAY. THE MAJORITY OF THE GLOBAL MODELS INDICATE THAT
THE BOUNDARY WILL REMAIN NORTH OF THE FORECAST AREA...BUT AM A
LITTLE BIT CONCERNED GIVEN THE TIME OF YEAR THAT THE COLD AIRMASS
NORTH OF THE BOUNDARY MAY BE STRONG ENOUGH TO PUSH THE FRONT INTO
PORTIONS OF THE FORECAST AREA. FOR NOW WILL FOLLOW MODEL CONSENSUS
KEEPING THE BOUNDARY NORTH OF THE AREA AND MONITOR TRENDS CLOSELY
FOR ANY NECESSARY ADJUSTMENTS. IF THE BOUNDARY PUSHES SOUTHWARD INTO
THE REGION SUNDAY NIGHT/MONDAY...IT SHOULD LIFT BACK NORTH OF THE
LOCAL AREA LATE MONDAY/MONDAY NIGHT IN ADVANCE OF ANOTHER COLD FRONT
PROGGED TO MOVE THROUGH THE AREA ON TUESDAY.

AS FOR FORECAST DETAILS...WILL KEEP THE FORECAST RAIN FREE FRIDAY
NIGHT THROUGH MONDAY WITH HIGH PRESSURE EXPECTED TO REMAIN IN
CONTROL OF THE AREAS WEATHER. THIS COULD POTENTIALLY CHANGE IN THE
SUNDAY NIGHT/MONDAY TIME FRAME IF THE FRONTAL BOUNDARY MENTIONED
ABOVE MANAGES TO SLIP INTO THE AREA. WITH A COLD FRONT EXPECTED TO
APPROACH THE REGION MONDAY NIGHT AND MOVE THROUGH ON TUESDAY...WILL
CARRY SLIGHT CHANCE POPS AREA WIDE.

TEMPERATURES ARE EXPECTED TO RUN WELL ABOVE NORMAL THROUGHOUT THE
LONG TERM PERIODS.

&&

.AVIATION /18Z TUESDAY THROUGH SUNDAY/...
W WINDS WILL GUST TO AROUND 20 KT THROUGH ABOUT 20Z. A BACKDOOR
COLD FRONT WILL DROP S THROUGH KCHS BY 01Z AND KSAV AROUND 08Z
SHIFTING WINDS TO THE N/NE. LOW CLOUDS WILL BE ASSOCIATED WITH
THE FRONT AND COULD BE MVFR AT TIMES AT BOTH TAF SITES THROUGH
AROUND DAYBREAK BUT GENERALLY NOT CONFIDENT ENOUGH TO INCLUDE
MENTION IN THE 18Z TAFS EXPCEPT AT KSAV TO INITIALIZE.

EXTENDED AVIATION OUTLOOK...VFR CONDITIONS ARE GENERALLY EXPECTED
TO PREVAIL THROUGH THURSDAY. THERE IS A CHANCE THAT SOME MVFR CIGS
COULD DEVELOP LATE TUESDAY NIGHT AND EARLY WEDNESDAY...MAINLY AT
THE CHARLESTON TERMINAL. MVFR OR LOWER CONDITIONS WILL THEN BE
POSSIBLE ONCE AGAIN THURSDAY NIGHT INTO FRIDAY AHEAD OF ANOTHER
COLD FRONT. VFR CONDITIONS ARE THEN EXPECTED FRIDAY NIGHT AND
SATURDAY. COULD SEE SOME REDUCED CIGS/VSBYS AGAIN LATE SATURDAY
NIGHT/EARLY SUNDAY.

.MARINE...
WITH THE LOW-LEVEL WINDS ON THE DECLINE AS THE COLD FRONT FROM THE
N AND W APPROACHES...HAVE CANCELLED THE SMALL CRAFT ADVISORIES FOR
THE NRN SC WATERS AND OUTER GA WATERS. THE NEXT CONCERN WILL BE A
BACKDOOR COLD FRONT WHICH WILL CAUSE PRES GRADIENTS TO PINCH
TONIGHT AS IT WORKS TO THE S. WE THINK A SCA WILL NEED TO BE
REISSUED LATER TODAY FOR MUCH OF THE SOUTH CAROLINA WATERS AS NE
WINDS INCREASE AND SURGE. THE SURGE WILL BE A BIT LATER REACHING
GEORGIA WATERS TONIGHT. SEAS 2-4 FT THIS MORNING WILL SUBSIDE TO 2
FT OR LESS LATER TODAY...THEN INCREASE FROM N TO S
TONIGHT...HIGHEST OVER CHARLESTON COUNTY WATERS.

A DECENT NORTHEASTERLY SURGE IS EXPECTED WEDNESDAY AND WEDNESDAY
NIGHT AS HIGH PRES BUILDS NORTH OF THE REGION...AND SMALL CRAFT
ADVISORIES WILL LIKELY BE NEEDED FOR PORTIONS OF THE WATERS...
PARTICULARLY THE OUTER GEORGIA WATERS. IMPROVING CONDITIONS ARE
THEN EXPECTED ON THURSDAY AS HIGH PRESSURE BUILDS INTO THE WESTERN
ATLANTIC ALLOWING THE PINCHED GRADIENT OVER THE MARINE AREA TO
RELAX. THIS WILL BE SHORT LIVED HOWEVER...AS WINDS/SEAS INCREASE
LATE THURSDAY NIGHT THROUGH FRIDAY IN ADVANCE OF AN APPROACHING
COLD FRONT...WITH HEADLINES CERTAINLY POSSIBLE OVER PORTIONS OF
THE WATERS ONCE AGAIN. IMPROVING CONDITIONS ARE EXPECTED FRIDAY
NIGHT AND OVER THE WEEKEND AS HIGH PRESSURE BUILDS BACK INTO THE
REGION...WITH WINDS AND SEAS EXPECTED TO REMAIN BELOW ADVISORY
LEVELS.
