AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHARLESTON SC
404 PM EDT SUN MAY 23 2010

.SYNOPSIS...
A HIGH PRESSURE WEDGE WILL PERSIST INLAND MONDAY AND TUESDAY. LOW
PRESSURE DEVELOPING EAST OF THE BAHAMAS WILL MOVE NORTH AND
NORTHWEST THROUGH MID WEEK...MOST LIKELY REMAINING OVER THE
ATLANTIC...BEFORE SHIFTING EAST LATE IN THE WEEK.

&&

.NEAR TERM /THROUGH TONIGHT/...
THE AREA WILL REMAIN ON THE WESTERN SIDE OF AN UPPER LOW DROPPING
SOUTHEAST FROM THE MID-ATLANTIC REGION. SHOWERS AND THUNDERSTORMS
ARE BECOMING MORE WIDESPREAD FROM THE MID-ATLANTIC SOUTHWARD INTO
EASTERN SOUTH CAROLINA. THE STORMS ACROSS THE SC MIDLANDS WILL
DRIFT INTO OUR FORECAST AREA THIS EVENING AS THE SEA BREEZE SLOWLY
MOVES INLAND. WE THINK THE BEST SHOWER/TSTM COVERAGE WILL BE
ACROSS INTERIOR PORTIONS OF SOUTHEAST SOUTH CAROLINA AND WILL
HIGHLIGHT OUR HIGHEST POPS /40S/ THERE. MOST OF THE ACTIVITY SHOULD
REMAIN AWAY FROM THE COAST BUT THE N/NW STEERING FLOW MAY ALLOW
FOR RAIN TO MAKE IT TO THE BEACHES. A FEW STORMS MAY BECOME SEVERE
THROUGH THIS EVENING WITH DAMAGING WINDS AND LARGE HAIL. ALTHOUGH
MOST LOCALES SHOULD REMAIN DRY AFTER MIDNIGHT...CANNOT COMPLETELY
RULE OUT ISOLATED SHOWERS/STORMS DUE TO THE APPROACHING UPPER LOW.
PATCHY FOG IS ALSO POSSIBLE...ESPECIALLY IN AREAS THAT SEE
RAIN...BUT WILL HOLD OUT OF THE FORECAST FOR NOW. LOWS WILL BE IN
THE MID TO UPPER 60S AWAY FROM THE SLIGHTLY MILDER BEACHES.

&&

.SHORT TERM /MONDAY THROUGH WEDNESDAY NIGHT/...
MONDAY...MID AND UPPER CYCLONE OVER NC WILL DROP EAST OF THE AREA
DURING THE DAY. AT THE SAME TIME AT TH E SURFACE...A HIGH PRESSURE
WEDGE BEGINS TO STRENGTHEN ACROSS THE LOCAL REGION. WHILE THIS
OCCURS...LOW PRESSURE IS SLOWLY DEEPENING EAST AND NE OF THE
BAHAMAS. WITH A DEEPER AND STRENGTHENING EASTERLY FLOW BETWEEN THESE
TWO SURFACE FEATURES RESULTING IN AN INCREASE IN LOW LEVEL
CONVERGENCE...WE LOOK FOR AN INCREASE IN CLOUDINESS AND OUR RAIN
CHANCES MONDAY. WITH LESS SHEAR AND INSTABILITY AND POOR LAPSE
RATES...WE LOOK FOR A DECREASE IN T-STORM CHANCES...WITH MUCH OF THE
PRECIP IN THE FORM OF SHOWERS. HOWEVER...WITH A 40 KT JET STREAK TO
MOVE IN LATE...SHORT WAVES TO MOVE INTO SC IN ASSOCIATION WITH THE
MID AND UPPER CYCLONE...AND COLDER 500 TEMPS DOWN TO -11 OR -12C WE
STILL COULD EXPERIENCE A FEW STRONGER THUNDERSTORMS WITH THE
INTERACTION OF BOUNDARIES. RAIN CHANCES WILL BE MAINLY IN THE 40 TO
50 PERCENT RANGE...EXCEPT SOME 60 PERCENT PROBABILITIES ION BERKELEY
AND DORCHESTER IN CLOSER PROXIMITY TO SHORT WAVES AND JET STREAK
ALOFT. TEMPS WILL BE NOTICEABLY LOWER THAN RECENT DAYS DUE TO THE
ONSHORE FETCH...AND THE INCREASED CLOUD COVER AND PRECIP. WE WILL
SHOW MAINLY UPPER 70S AND LOWER 80S...EXCEPT A FEW MID 80S ACROSS
FAR SOUTHERN AREAS IF THEY RECEIVE ENOUGH BREAKS OF SUNSHINE.

MONDAY NIGHT AND TUESDAY...HIGH PRESSURE WEDGE REMAINS ANCHORED
INLAND...WITH ATLANTIC LOW PRESSURE STILL FAR TO THE SE AND MOVING
ONLY SLOWLY NORTH AND NW. THE MID AND UPPER CYCLONE NEARBY MONDAY
EVENING WILL BECOME ABSORBED BY A THE MID AND UPPER CYCLONE
ASSOCIATED WITH THE SURFACE LOW OF THE ATLANTIC. RAIN CHANCES ARE
DRIVEN MAINLY BY LOW LEVEL CONVERGENCE MONDAY NIGHT AND
TUESDAY...AIDED BY WEAK SHORT WAVES ALOFT ROTATING AROUND THE MID
AND UPPER CYCLONE.

TUESDAY NIGHT THROUGH WEDNESDAY NIGHT...WITH THE SURFACE LOW
CO-LOCATED UNDER THE MID AND UPPER CYCLONE AND A BLOCKING RIDGE TO
THE NORTH OF THE SYSTEM...THE ATLANTIC LOW WILL STRUGGLE TOO MOVE
TOO FAR NORTH THROUGH THE MIDDLE OF THE WEEK. ALTHOUGH IT MAY REACH
OUR LATITUDE...PRESENT INDICATIONS ARE THAT THE SYSTEM WILL STAY FAR
OFFSHORE OVER THE ATLANTIC. RAIN CHANCES WILL BE IN THE 20-30
PERCENT RANGE...HIGHEST OVER THE COASTAL AREAS AND IN THE ATLANTIC
BASED ON THE LOW REMAINING WELL REMOVED FROM THE LOCAL AREA. THAT
COULD CHANGE SHOULD THE TRACK/STRENGTH OF THE SYSTEM DEVIATE FROM
THE LATEST THINKING. TEMPS WILL NOT STRAY TOO FAR FROM NORMAL.

ALTHOUGH THE LOW WILL LIKELY STAY IN THE ATLANTIC...WE STILL COULD
EXPERIENCE SOME IMPACTS LOCALLY. THAT WOULD BE THE RISK OF
BEACH EROSION....AND THE POSSIBILITY OF SHALLOW COASTAL FLOODING
WHICH WOULD COINCIDE WITH THE UPCOMING ASTRONOMICAL HIGH TIDES WITH
THE FULL MOON. WE WILL DISCUSS THESE CONDITIONS IN OUR HAZARDOUS
WEATHER OUTLOOK.

&&

.LONG TERM /THURSDAY THROUGH SATURDAY/...
AN UPPER RIDGE OVER THE GREAT LAKES REGION WILL PIN THE ATLANTIC
LOW...DEVELOPING A BLOCKING PATTERN SUGGESTIVE OF A MEANDERING
SURFACE SYSTEM THROUGH AT LEAST THURSDAY. ONCE THE UPPER LOW WEAKENS
INTO MORE OF A PROGRESSIVE TROUGH...THE SURFACE LOW WILL BE TAKEN
EAST FURTHER INTO THE ATLANTIC. THIS PATTERN SHIFT WILL ALLOW HIGH
PRESSURE AT THE SURFACE AND ALOFT TO REBUILD OVER THE REGION FOR
LATE WEEK INTO THE WEEKEND.

EXPECT RAIN CHANCES TO BE LOWER THURSDAY THROUGH SATURDAY AS A
RESULT. PERSISTENTLY CLOUDY SKIES WILL ALSO BREAK BY LATE WEEK...AND
WHEN COMBINED WITH INCREASING HEIGHTS ALOFT...WILL SUPPORT A WARMING
TREND INTO THE WEEKEND.

&&

.AVIATION /20Z SUNDAY THROUGH FRIDAY/...
AS OF 17Z SCATTERED SHOWERS AND STORMS HAVE DEVELOPED IN
NORTHEASTERN SOUTH CAROLINA AND ARE FORECAST TO SHIFT SOUTHWARD
OVER TIME THIS AFTERNOON. NORTH/NORTHWESTERLY FLOW ALOFT WILL
ALLOW ANY SHOWER OR STORM TO MOVE SOUTHEAST TOWARDS THE
TERMINALS...WITH THE GREATEST CHANCE NEAR CHS. THUS HAVE INCLUDED
A TEMPO SHOWERS GROUP WITH CB AT CHS. THIS TEMPO GROUP HOWEVER MIGHT
NOT COMPLETELY COVER THE ENTIRE PERIOD IN WHICH SHOWERS MAY OCCUR
AT CHS INTO THE EVENING. SHOWERS AND AN ISOLATED STORM COULD ALSO
IMPACT THE SAV TERMINAL LATER THIS AFTERNOON INTO THE
EVENING...BUT CONFIDENCE IS TOO LOW TO INCLUDE AT THIS TIME.

AS THE UPPER LEVEL LOW TO THE NORTH OF THE AREA MOVES SOUTH
TONIGHT CIGS WILL LOWER INTO THE MORNING HOURS...ESPECIALLY AT
CHS...ALONG WITH THE DEVELOPMENT OF RAIN SHOWERS ONCE AGAIN.
MODELS ARE CURRENTLY HOLDING RAIN OFF UNTIL THE AFTERNOON AT
SAV...THUS RAIN IS NOT YET INCLUDED IN THE TAF FOR MONDAY. MODELS
ARE ALSO HINTING AT GROUND FOG TONIGHT AT BOTH TERMINALS WITH MVFR
VSBYS...BUT PERSISTENT MVFR VSBYS ARE NOT CURRENTLY ANTICIPATED.

EXTENDED AVIATION OUTLOOK...MVFR CONDITIONS POSSIBLE AT TIMES MONDAY
AFTERNOON THROUGH WEDNESDAY...WITH AN INCREASE IN RAIN CHANCES.

&&

.MARINE...
TONIGHT...AN EAST TO NORTHEAST FLOW REGIME WILL PERSIST AS HIGH
PRES SLOWLY STRENGTHENS N OF THE AREA. WINDS WILL GENERALLY
REMAIN 10 KT OR LESS WITH SEAS 3-4 FT OR LESS...MAINLY IN SOUTHEAST
SWELL.

MONDAY THROUGH FRIDAY...THE PRESSURE GRADIENT STEADILY TIGHTENS ACROSS
THE MARINE COMMUNITY DURING THE EARLY AND MIDDLE PART OF THE WEEK.
INITIALLY THIS IS A RESULT OF STRONGER HIGH PRESSURE BUILDING FROM
THE NORTH WITH A RESULTING WEDGE SETTING UP INLAND. BUT AS LOW
PRESSURE OVER THE SW ATLANTIC MOVES NORTH AND NW IN AN AREA WELL
OFF THE SE COAST...OUR GRADIENT PINCHES FURTHER...DEPENDING UPON
THE TRACK...STRENGTH AND TIMING OF THAT LOW. CONDITIONS APPEAR TO
REMAIN BELOW ANY SCA CONDITIONS MONDAY...CAPPING WINDS AND SEAS AT
15 KT AND 4 FEET...RESPECTIVELY.

BUT WINDS AND SEAS WILL BE ON THE INCREASE STARTING MONDAY NIGHT AND
TUESDAY...AS THE ATLANTIC LOW SHIFTS A BIT CLOSER TO THE WATERS.
THERE IS STILL SOME UNCERTAINTY ON THE STRENGTH OF THE PINCHING
BETWEEN THIS LOW AND THE INLAND WEDGE. AFTER CONSIDERING OUR
INTER-OFFICE COORDINATION...WE HAVE DECIDED AGAINST RAISING ANY
SCA/S AT THIS TIME. BUT ODDS DO FAVOR SCA/S WILL BE REQUIRED AT SOME
POINT FOR THE MID WEEK PERIOD. IN FACT WE STILL CANNOT ENTIRELY RULE
OUT THE POSSIBILITY OF GALES.

GIVEN THAT THERE IS STILL MUCH UNCERTAINTY REGARDING THE DEVELOPMENT
AND EVENTUAL TRACK AND STRENGTH OF THIS SYSTEM. ALL MARINERS ARE
URGED TO REMAIN ABREAST OF THE MARINE FORECAST FOR FURTHER UPDATES.

PREFERRED MODEL SOLUTIONS INDICATE THE LOW PRESSURE SYSTEM WILL
DRIFT BACK EAST THROUGH THE ATLANTIC AROUND THURSDAY...ALLOWING
WINDS AND SEAS TO DIMINISH BY LATE IN THE WEEK. WILL THUS INDICATE
SLOWLY IMPROVING CONDITIONS FOR THURSDAY AND FRIDAY.

RIP CURRENTS...WE RECEIVED REPORTS OF RIP CURRENTS AT FOLLY BEACH
THE PAST 2 DAYS...AND CONDITIONS LOOK JUST AS GOOD IF NOT BETTER FOR
MONDAY. WITH A PERSISTING ONSHORE WIND AND A CONTINUATION OF SMALL
2-3 FOOT SWELLS AT THE BEACHES...PLUS THE UPCOMING FULL MOON...WE
HAVE OPTED FOR A MODERATE RISK OF RIP CURRENTS MONDAY. CONDITIONS
APPEAR FAVORABLE FOR RIP CURRENTS AGAIN TUESDAY AND WEDNESDAY...AS
EVEN LARGER SWELLS IMPACT THE BEACHES IN RESPONSE TO LOW PRESSURE IN
THE ATLANTIC.
