AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHARLESTON SC
142 PM EDT FRI APR 1 2011

.SYNOPSIS...
HIGH PRESSURE WILL PREVAIL INTO EARLY NEXT WEEK. A COLD FRONT
WILL THEN MOVE THROUGH THE AREA TUESDAY INTO WEDNESDAY...FOLLOWED
BY HIGH PRESSURE FOR THE MIDDLE AND LATTER PART OF NEXT WEEK.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
GUSTY WEST WINDS AND CHANGEABLE SKIES...VARYING FROM MOSTLY SUNNY
TO MOSTLY CLOUDY...WILL ACCOMPANY HIGHS MAINLY IN THE 60S EXCEPT
PERHAPS NEAR 70F FAR S THROUGH THIS AFTERNOON.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH MONDAY/...
PARTLY CLOUDY SKIES WILL GIVE WAY TO MOSTLY CLEAR CONDITIONS TONIGHT.
HIGH PRESSURE WILL REMAIN ANCHORED WELL TO THE SOUTH OVER CENTRAL
FLORIDA BUT MAY BUILD FAR ENOUGH UP ALONG THE GEORGIA COAST TO
ALLOW THE BOUNDARY LAYER TO DECOUPLED ACROSS THE SOUTHERN ZONES.
CLEAR SKIES AND FAIRLY LIGHT WINDS WILL ALLOW TEMPERATURES TO DROP
LOWER-MID 40S WITH UPPER 40S-LOWER 50S AT THE COAST. A FEW UPPER
30S CAN NOT BE COMPLETELY RULED OUT IN SHELTERED AREAS...BUT THERE
ARE NO CONCERNS FOR FROST.

SATURDAY...SURFACE HIGH PRESSURE WILL BUILD TOWARD THE SOUTHEAST
STATES ON SATURDAY...WHILE THE AXIS OF THE MAIN UPPER TROUGH
CROSSES INTO THE ATLANTIC. SOLID OFFSHORE FLOW WITH A DOWNSLOPE
COMPONENT...COMBINED WITH MOSTLY SUNNY SKIES BY THE
AFTERNOON...WILL SUPPORT HIGH TEMPERATURES NEAR SEASONAL NORMALS
IN THE LOW TO MID 70S. THE PRESSURE GRADIENT WILL REMAIN TIGHT FOR
MOST OF THE DAYTIME HOURS...AND EXPECT SOME AFTERNOON BREEZES AS A
RESULT. ONCE THE SURFACE HIGH BECOMES CENTERED OVER THE FORECAST
AREA SATURDAY NIGHT...THE WEAKENING GRADIENT WILL ALLOW WINDS TO
DIMINISH. THESE LIGHT NIGHTTIME WINDS...ALONG WITH MOSTLY CLEAR
SKIES...WILL SET UP IDEAL RADIATIONAL COOLING CONDITIONS. THUS LOW
TEMPERATURES WILL STILL BE SLIGHTLY COOLER THAN NORMAL...RANGING
FROM THE LOWER 40S INLAND TO AROUND 50 CLOSER TO THE COAST.

SUNDAY...THE SURFACE HIGH WILL CONTINUE TO SLIP EASTWARD...EVENTUALLY
SHIFTING INTO THE ATLANTIC BY SUNDAY NIGHT. AN UPPER LEVEL RIDGE
BUILDING FROM THE WEST WILL FURTHER SUPPORT A WARMING TREND AND RAIN
FREE WEATHER ON SUNDAY. LIGHT WINDS EARLY IN THE DAY WILL BE
DOMINATED BY THE SEABREEZE ALONG THE COAST...BEFORE A SOLID
SOUTHERLY FLOW DEVELOPS ON THE WESTERN PERIPHERY OF THE ATLANTIC
HIGH. HIGH TEMPERATURES INLAND WILL REACH THE UPPER 70S SUNDAY
AFTERNOON...WHILE THE CHARLESTON TRI COUNTY AREA AND COASTAL
LOCATIONS COULD REMAIN IN THE LOWER 70S UNDER COOLER ONSHORE FLOW.
LOW TEMPERATURES SUNDAY NIGHT WILL BE MILDER WITHIN THE INCREASING
SOUTHERLY WINDS.

MONDAY...THE ATLANTIC SURFACE HIGH AND UPPER LEVEL RIDGE WILL
CONTINUE TO DRIFT EASTWARD ON MONDAY...AS A COMPLEX LOW SYSTEM
DEVELOPS TO THE WEST. BOTH GFS AND ECMWF KEEP PRECIPITATION WEST
OF THE REGION THROUGH MONDAY AFTERNOON...AND WILL THEREFORE KEEP
RAIN CHANCES BELOW 15 PERCENT AT THIS TIME. STRONG WARM ADVECTION
WITHIN SOUTHERLY FLOW...AS WELL AS LINGERING RIDGING ALOFT...SUGGESTS
TEMPERATURES WILL REACH THE LOWER 80S AWAY FROM THE LOCALLY COOLER
COASTLINE.

&&

.LONG TERM /MONDAY NIGHT THROUGH THURSDAY/...
AN ELONGATED UPPER TROUGH AND SURFACE LOW SYSTEM WILL SWEEP INTO
THE TENNESSEE AND OHIO VALLEYS MONDAY NIGHT INTO TUESDAY. THERE
REMAINS SOME TIMING DIFFERENCES BETWEEN THE MEDIUM RANGE MODELS
REGARDING THE ASSOCIATED FRONTAL PASSAGE ...HOWEVER GENERAL
CONSENSUS IS THAT THUNDERSTORM ACTIVITY WILL BE IMPACTING WESTERN
ZONES BY TUESDAY MORNING. EXPECT SOLID PRECIPITATION CHANCES AS THE
SYSTEM MOVES THROUGH THE FORECAST AREA ON TUESDAY...AND HAVE
INDICATED POPS IN THE 30 TO 40 PERCENT RANGE. MODELS ARE
DEPICTING VERY STRONG UPPER DYNAMICS ACCOMPANYING THE FRONT...AND
CONSIDERING WARM TEMPERATURES NEAR 80 DEGREES AND DECENT
INSTABILITY...ORGANIZED STRONG TO PERHAPS SEVERE CONVECTION COULD
OCCUR ON TUESDAY.

THE UPPER TROUGH AND SURFACE FRONT WILL RAPIDLY SHIFT OFFSHORE BY
WEDNESDAY MORNING...WITH DRY AIR QUICKLY FILTERING INTO THE REGION
BEHIND THE SYSTEM. EXPECT RAIN CHANCES TO DIMINISH FROM WEST TO
EAST EARLY WEDNESDAY MORNING...AS SURFACE HIGH PRESSURE ONCE AGAIN
TRACKS OVER THE SOUTHEAST STATES INTO THE ATLANTIC THROUGH LATE
WEEK. HIGH TEMPERATURES ON WEDNESDAY WILL BE CONSIDERABLY COOLER
BEHIND THE FRONT...LIKELY SUPPRESSED IN THE UPPER 60S. THE COOLER
CONDITIONS WILL BE BRIEF...AS A WARMING TREND IS THEN EXPECTED
THURSDAY INTO LATE WEEK. HAVE KEPT RAIN FREE CONDITIONS FROM
WEDNESDAY AFTERNOON THROUGH FRIDAY.

&&

.AVIATION /18Z FRIDAY THROUGH WEDNESDAY/...
VFR THROUGH SATURDAY AT KCHS/KSAV. WIND GUSTS AS HIGH AS 25-30 KT
WILL CONTINUE THIS AFTERNOON...THEN DECOUPLING SHOULD PROMOTE
DIMINISHING WINDS AFTER SUNSET. LOW LEVEL WIND SHEAR COULD DEVELOP
OVERNIGHT INTO SATURDAY MORNING...BUT ODDS FAVOR DIRECTIONAL/SPEED
SHEAR WITHIN 2 KFT AGL REMAINING JUST BELOW LLWS THRESHOLDS.
GUSTY W WINDS WILL REDEVELOP AS THE MIXED LAYER DEEPENS BY MID TO
LATE MORNING SATURDAY.

EXTENDED AVIATION OUTLOOK...MVFR/IFR VSBYS IN SHOWERS/TSTMS
POSSIBLE TUESDAY AFTERNOON OR EVENING.

&&

.MARINE...
RAISED SMALL CRAFT ADVISORIES FOR NEARSHORE WATERS FROM EDISTO
BEACH TO ALTAMAHA SOUND INTO EARLY THIS EVENING...AS OFFSHORE WIND
GUSTS 25-30 KT WILL CONTINUE. MAINTAINED THE ONGOING SMALL CRAFT
ADVISORY FOR AMZ374 UNTIL 5 PM...BUT WILL ASSESS POTENTIAL FOR
EXTENDING THIS ADVISORY THROUGH AT LEAST TONIGHT AS 12Z GUIDANCE
DEPICTS ANOTHER SURGE OF STRONG W/NW WINDS OVERNIGHT. N OF EDISTO
BEACH...ELEVATED OFFSHORE WINDS AND SEAS WILL CONTINUE THIS
AFTERNOON...BUT WINDS WILL REMAIN CAPPED AT AROUND 20 KT AND
OFFSHORE WINDS SHOULD TRANSLATE TO SEAS NO HIGHER THAN 3-4 FT
WITHIN 20 NM OF THE COAST.

WINDS COULD DIMINISH SOMEWHAT THIS EVENING...THEN 12Z GUIDANCE
DEPICTS ANOTHER SURGE OF W/NW WINDS OVERNIGHT. WILL ASSESS NEED TO
EXPANDED SCA COVERAGE.

HIGH PRESSURE WILL BUILD INTO THE AREA THROUGH EARLY NEXT WEEK. A
TIGHT PRESSURE GRADIENT WILL LINGER ON SATURDAY...SUPPORTING
MODERATE WEST WINDS UP TO 15 TO 20 KT IN PORTIONS OF THE WATERS.
WIND SPEEDS WILL THEN STEADILY DIMINISH ON SUNDAY...AS THE SURFACE
HIGH MOVES DIRECTLY OVER THE FORECAST AREA AND WEAKENS THE
GRADIENT.

THE SURFACE HIGH WILL STEADILY SLIP INTO THE ATLANTIC ON
MONDAY...AS A COLD FRONT APPROACHES THE REGION FROM THE WEST. THE
COMBINATION OF A RAPIDLY TIGHTENING PRESSURE GRADIENT AND AN
INTENSE LOW LEVEL JET AHEAD OF THE FRONT WILL SUPPORT SURGING
SOUTHERLY WINDS LATE MONDAY INTO TUESDAY. MODELS ARE INDICATING
WINDS INCREASING TO 20 TO 25 KT AND SEAS BUILDING TO 8 TO 9 FT IN
THE OUTER WATERS. SMALL CRAFT ADVISORIES MAY EVENTUALLY BE NEEDED
FOR PORTIONS OF THE MARINE AREA EARLY NEXT WEEK.
