AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHARLESTON SC
202 PM EDT FRI APR 15 2011

.SYNOPSIS...
HIGH PRESSURE WILL PREVAIL THROUGH TODAY. A WEAK WARM FRONT WILL
LIFT NORTH ACROSS THE AREA TONIGHT...FOLLOWED BY THE PASSAGE OF
A COLD FRONT LATE SATURDAY. HIGH PRESSURE WILL THEN BUILD BACK INTO
THE REGION INTO LATE NEXT WEEK.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
ONGOING FORECAST IS IN GOOD SHAPE AND ONLY MINOR ADJUSTMENTS WILL
BE MADE FOR THE EARLY AFTERNOON UPDATE. STRATOCUMULUS MOVING
ONSHORE REMAINS VOID OF ANY NOTABLE RETURNS ON RADAR...SO CONTINUE
TO ANTICIPATED RAIN FREE CONDITIONS THROUGH THE REMAINDER OF THE
DAY. TEMPERATURES REMAIN ON TRACK TO TOP OUT IN THE UPPER 70S TO
LOWER 80S AWAY FROM THE COAST. UPDATE OUT SHORTLY.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH MONDAY/...
A CLOSED UPPER LEVEL LOW AND ASSOCIATED SURFACE LOW PRESSURE SYSTEM
WILL LIFT NORTHEAST ACROSS THE OHIO VALLEY TONIGHT AS SURFACE HIGH
PRESSURE SHIFTS EAST ACROSS NEW ENGLAND. THIS WILL ALLOW A WARM
FRONT TO LIFT ACROSS THE AREA TONIGHT. THERE WILL BE A SLIGHT OR
LOW CHANCE OF SHOWERS AND PERHAPS A FEW THUNDERSTORMS SOUTH OF THE
SAVANNAH RIVER THIS EVENING WITH THE FRONT. THE FOCUS FOR SHOWERS/
THUNDERSTORMS WILL THEN SHIFT TO SOUTHEAST SOUTH CAROLINA AFTER
MIDNIGHT...ESPECIALLY THE CHARLESTON TRI-COUNTY AREA...DUE TO THE
PRESENCE OF DEEPER MOISTURE AND STRONGER FORCING FOR ASCENT.
ABUNDANT CLOUD COVER...AN ONSHORE FLOW WITHIN A WELL MIXED
BOUNDARY LAYER AND DEVELOPING WARM AIR ADVECTION ALOFT WILL KEEP
LOWS IN THE LOWER TO MID 60S TONIGHT.

A COLD FRONT WILL BE APPROACHING FROM THE WEST SATURDAY AS AN UPPER
CLOSED LOW WEAKENS/BECOMES NEGATIVELY TILTED AS IT PUSHES INTO THE
GREAT LAKES REGION. GOOD FORCING FOR ASCENT AHEAD OF THESE FEATURES
ALONG WITH ADDITIONAL FORCING FROM AN UPPER JET WILL HELP DRIVE A
LINE OF SHOWERS AND TSTMS THROUGH OUR FORECAST AREA ALONG/AHEAD OF
THE SURFACE COLD FRONT. RAIN CHANCES LOOK TO INCREASE THROUGH THE
DAY WITH THE BEST CHANCES ACROSS SOUTHERN SC WHICH WILL BE CLOSER TO
THE BETTER DYNAMICS. ALTHOUGH THERE COULD BE QUITE A BIT OF
PRE-FRONTAL CLOUD COVER...MODELS ARE INDICATING ABOUT 1500-2000 J/KG
OF SURFACE BASED CAPE...SO THERE IS A CONCERN FOR STRONG TO SEVERE
STORMS GIVEN THE STRONG LOW-LEVEL WIND FIELDS EXPECTED TO BE IN
PLACE. THE SPC HAS OUTLINED THE ENTIRE AREA IN A SLIGHT RISK FOR
SEVERE STORMS AND WILL CONTINUE TO HIGHLIGHT THIS THREAT IN THE
HAZARDOUS WEATHER OUTLOOK /HWO/. CANNOT RULE OUT WINDS STRONG ENOUGH
TO WARRANT A WIND ADVISORY...ESPECIALLY ACROSS THE CHARLESTON
TRI-COUNTY AREA AND WILL ALSO MENTION THIS IN THE HWO.

RAIN CHANCES WILL DIMINISH SATURDAY EVENING AS THE FRONT PUSHES
OFFSHORE WITH DRY WEATHER RETURNING UNDER HIGH PRESSURE THROUGH
MONDAY.

LAKE WINDS...A 40-45 KT LOW LEVEL JET WILL CROSS THE AREA IN ADVANCE
OF A COLD FRONT SATURDAY. DEPENDENT ON THE AMOUNT OF MIXING THAT
TAKES PLACE WE WILL MOST LIKELY SEE A LAKE WIND ADVISORY ON LAKE
MOULTRIE.

&&

.LONG TERM /MONDAY NIGHT THROUGH THURSDAY/...
HIGH PRESSURE WILL PREVAIL OVER THE WESTERN ATLANTIC THROUGH THE
LONG TERM PERIOD...WITH UPPER LEVEL RIDGING BUILDING CONSIDERABLY
OVER THE SOUTHEAST STATES AND WESTERN ATLANTIC TOWARD THE MIDDLE OF
NEXT WEEK. STRONG SUBSIDENCE WILL GENERALLY KEEP RAIN-FREE
CONDITIONS IN PLACE...HOWEVER A STRENGTHENING RETURN FLOW TOWARD THE
END OF THE FORECAST PERIOD COULD RESULT IN ISOLATED DIURNAL
CONVECTION WITH PROBABILITIES TOO LOW TO INCLUDE IN THE FORECAST AT
THIS TIME. TEMPERATURES WILL BE ON A WARMING TREND THROUGH THE
PERIOD...WITH THE POTENTIAL TO BECOME WELL ABOVE NORMAL BY THE
MIDDLE OF NEXT WEEK.

&&

.AVIATION /18Z FRIDAY THROUGH WEDNESDAY/...
VFR CONDITIONS ARE EXPECTED AT BOTH TERMINALS THROUGH THE
REMAINDER OF THE AFTERNOON AND INTO THE EVENING HOURS. SHOULD SEE
CONDITIONS DROP TO MVFR LEVELS ALONG WITH THE POTENTIAL FOR
SHOWERS FOR ROUGHLY A 4 HOUR PERIOD BETWEEN MIDNIGHT AND DAYBREAK
SATURDAY AS A WARM FRONT PROGRESSES NORTHWARD THROUGH THE LOCAL
AREA. MVFR CIGS MAY CONTINUE THROUGH MID-MORNING SATURDAY...BEFORE
CONDITIONS IMPROVE TO VFR LEVELS THROUGH THE EARLY AFTERNOON
HOURS. GUSTY SURFACE WINDS WILL ALSO IMPACT THE TERMINALS FROM MID
MORNING SATURDAY RIGHT THROUGH THE AFTERNOON HOURS...AS A STRONG
COLD FRONT APPROACHES FROM THE WEST. FREQUENT GUSTS OF 30 TO 35
KNOTS ARE EXPECTED...WITH ISOLATED HIGHER GUSTS POSSIBLE.

EXTENDED AVIATION OUTLOOK...MVFR OR LOWER CONDITIONS ARE POSSIBLE
INTO SATURDAY EVENING...WITH THE HIGHEST PROBABILITIES OF SUB-VFR
WEATHER EXPECTED IN AFTERNOON/EARLY EVENING IN ASSOCIATION WITH
SHOWERS AND THUNDERSTORMS ALONG A COLD FRONT. GUSTY SURFACE WINDS
ARE ALSO EXPECTED THROUGH SATURDAY AFTERNOON. VFR CONDITIONS ARE
EXPECTED TO RETURN SATURDAY NIGHT THROUGH EARLY NEXT WEEK.

&&

.MARINE...
HIGH PRESSURE NORTH OF THE REGION WILL MAINTAIN AN ONSHORE FLOW
TODAY...WITH OCCASIONAL TIGHTENING OF THE SURFACE PRESSURE GRADIENT
RESULTING IN WINDS AS HIGH AS 15-20 KT AT TIMES. THE PERSISTENT
ONSHORE FLOW WILL ALLOW FOR GRADUAL BUT STEADY BUILDING OF SEAS
TODAY...WITH HEIGHTS EXPECTED TO REACH 3-4 FT THROUGHOUT THE
WATERS BY LATE THIS AFTERNOON.

A WARM FRONT WILL LIFT ACROSS THE WATERS TONIGHT...WITH SOUTHEAST
WINDS VEERING SOUTH IN ITS WAKE. A STRENGTHENING LOW LEVEL JET WILL
RESULT IN SOLID 15-20 KT WINDS ACROSS THE WATERS TONIGHT. SEAS
WILL CONTINUE TO BUILD WITH THE FAVORABLE FETCH...AND COULD
APPROACH SMALL CRAFT ADVISORY LEVELS TOWARD DAYBREAK SATURDAY OVER
PORTIONS OF THE WATERS.

SATURDAY THROUGH WEDNESDAY...SMALL CRAFT ADVISORIES ARE EXPECTED
SATURDAY INTO SATURDAY EVENING AS A COLD FRONT PUSHES THROUGH THE
AREA. VERY STRONG WINDS OFF THE SURFACE ARE EXPECTED WITH THE FRONT
AND CANNOT RULE OUT GALES BUT THERE IS SOME UNCERTAINTY IN MIXING OF
THESE WINDS TO THE SURFACE GIVEN THE COOLER NEARSHORE WATERS. BEYOND
20 NM...WARMER WATER TEMPERATURES SHOULD HELP LEAD TO MORE FAVORABLE
MIXING AND A BETTER CHANCE OF GALES. HIGH PRESSURE THEN RETURNS
SATURDAY NIGHT INTO EARLY NEXT WEEK AND NO HEADLINES ARE EXPECTED
DURING THIS PERIOD.

RIP CURRENTS...WITH THE APPROACH OF THE UPCOMING PERIGEE AND FULL
MOON AND THEIR RESULTING ASTRONOMICAL INFLUENCES...ALONG WITH
MODERATE TO STRONG SOUTHERLY WINDS...WE ARE LOOKING AT AN ENHANCED
RISK OF RIP CURRENTS ALONG THE BEACHES SATURDAY.

&&

.TIDES/COASTAL FLOODING...
THE UPCOMING PERIGEAN SPRING TIDES WILL NOT BE FAR FROM LEVELS
WHERE SHALLOW COASTAL FLOODING TYPICALLY OCCURS THIS WEEKEND INTO
EARLY NEXT WEEK. ANY ONSHORE FLOW COULD LEAD TO EVEN HIGHER LEVELS
AND WE WILL NEED TO CAREFULLY MONITOR THE SITUATION TO SEE IF ANY
COASTAL FLOOD ADVISORIES WILL BE REQUIRED.

&&

.CHS WATCHES/WARNINGS/ADVISORIES...
GA...NONE.
SC...NONE.
MARINE...NONE.
