AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHARLESTON SC
127 PM EDT SUN JUN 30 2013

...FLASH FLOOD WATCH ISSUED FOR SOUTHEAST SOUTH CAROLINA AND PARTS
OF SOUTHEAST GEORGIA THROUGH EARLY TUESDAY MORNING...

.SYNOPSIS...
A FRONT WILL REMAIN NEARLY STATIONARY OVER THE WESTERN CAROLINAS
AND NORTHERN GEORGIA. A VERY MOIST AIR MASS AHEAD OF THE FRONT
WILL ALLOW FOR HEAVY RAINFALL AT TIMES THROUGH AT LEAST MID WEEK.
OTHERWISE...HIGH PRESSURE WILL PREVAIL OFFSHORE WITH DEEP LOW
PRESSURE NORTH AND WEST OF THE AREA. BY THE END OF THE WEEK HIGH
PRESSURE WILL STRENGTHEN ALONG THE EAST COAST AND PERSIST THROUGH
NEXT WEEKEND.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
SHOWERS/TSTMS ARE STEADILY EXPANDING ACROSS THE AREA. LOW-LEVEL
CONVERGENCE IS STEADILY SHIFTING INLAND...SO WOULD EXPECT
ADDITIONAL ACTIVITY TO FIRE INLAND SOON. THERE IS QUITE A BIT OF
ACTIVITY DEVELOPING OVER NORTHERN FLORIDA WHICH WILL LIKELY IMPACT
THE AREA LATER. INCREASED POPS TO 90 PERCENT ACROSS THE
CHARLESTON AREA AND ACROSS THE INLAND ZONES WHERE HIGH RESOLUTION
GUIDANCE STILL PINS THE GREATEST COVERAGE THROUGH LATE AFTERNOON.

PER COORDINATION WITH ADJACENT WEATHER FORECAST OFFICES...A FLASH
FLOOD WATCH HAS BEEN ISSUED FOR MUCH OF SOUTHEAST SOUTH CAROLINA
AND PARTS OF SOUTHEAST GEORGIA THROUGH TUESDAY MORNING. 2-4 INCHES
WITH LOCALLY HIGHER AMOUNTS COMBINED WITH SATURATED GROUNDS WILL
PRODUCE AN ELEVATED RISK FOR FLASH FLOODING.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH WEDNESDAY/...
TONIGHT...CONVECTION WILL BEGIN TO DIMINISH IN COVERAGE THIS
EVENING...BUT EXPECT REDEVELOPMENT TO OCCUR OVERNIGHT...ESPECIALLY
TOWARD THE LOWER SOUTH CAROLINA COAST WHERE LOW-LEVEL ONSHORE
WIND TRAJECTORIES AND THE BEST SUPPORT FROM A LOW-LEVEL JET WILL
OCCUR. RAINFALL WILL CONTINUE TO BE HEAVY AT TIMES.

MONDAY THROUGH WEDNESDAY...MEDIUM RANGE GUIDANCE IN PRETTY GOOD
AGREEMENT INDICATING THE AREA REMAINING CAUGHT BETWEEN HIGH
PRESSURE OFFSHORE AND LOW PRESSURE TO THE WEST. ALTHOUGH HIGH
PRESSURE WILL BE SHIFTING WESTWARD WITH TIME IT APPEARS AS THOUGH
DEEP MOISTURE WILL PERSIST WITH PRECIPITABLE WATER VALUES OVER 2
INCHES THROUGH THE PERIOD. THIS PATTERN WILL FAVOR UNSETTLED
WEATHER GIVEN DIVERGENCE ASSOCIATED WITH THE UPPER JET AND SEVERAL
SHORTWAVES TRAVERSING THE AREA ON THE EAST SIDE OF THE TROUGH.
SEVERAL INCHES OF RAINFALL WILL BE POSSIBLE DURING THIS TIME WITH
LOCALLY HEAVY RAINFALL POSSIBLY LEADING TO SOME
FLOODING...ESPECIALLY WHERE STORMS MOVE OVER THE SAME AREAS. THE
THREAT OF SEVERE STORMS LOOKS PRETTY SMALL GIVEN THE MOIST
ATMOSPHERIC PROFILES...BUT IT LIKELY WILL NOT TAKE AS MUCH WIND TO
TOPPLE TREES GIVEN THE ALREADY SATURATED GROUND.

HIGH TEMPERATURES SHOULD BE HELD SLIGHTLY BELOW NORMAL WITH
OVERNIGHT LOWS SLIGHTLY ABOVE NORMAL.

&&

.LONG TERM /WEDNESDAY NIGHT THROUGH SATURDAY/...
DECENT MODEL AGREEMENT THIS PERIOD INDICATING DEEP HIGH PRESSURE
STRENGTHENING OVER THE EAST COAST THROUGH THE WEEKEND. WITH THE
DEEPEST MOISTURE SHIFTING WEST OF THE AREA THERE SHOULD BE LESS IN
THE WAY OF RAINFALL ACROSS THE AREA...MAINLY NEAR THE COAST EACH
MORNING TRANSITIONING INLAND THROUGH THE DAY. HIGH TEMPERATURES WILL
BE SLOWLY WARMING THROUGH THE PERIOD...LIKELY GETTING BACK ABOVE
NORMAL FOR THE WEEKEND.

&&

.AVIATION /17Z SUNDAY THROUGH THURSDAY/...
SCATTERED THUNDERSTORMS ARE EXPECTED TO INCREASE IN COVERAGE
THROUGHOUT THE AFTERNOON...PERIODICALLY REDUCING CONDITIONS TO AT LEAST
MVFR LEVELS DUE TO HEAVY DOWNPOURS AT BOTH KCHS AND KSAV. DUE TO
CURRENT RADAR TRENDS...HAVE INITIATED KCHS WITH A +TSRA TEMPO GROUP
WITH CONDITIONS SLIGHTLY DELAYED AT KSAV. PLENTY OF
MOISTURE WILL CONTINUE OVERNIGHT...BUT EXPECT CONVECTION TO DIMINISH
AFTER SUNSET. HOWEVER...SHOWERS COULD ONCE AGAIN INITIATE BY EARLY
MONDAY MORNING...ONCE AGAIN INCREASING CHANCES FOR MVFR CONDITIONS.

EXTENDED AVIATION OUTLOOK...SCATTERED TO NUMEROUS SHOWERS AND
THUNDERSTORMS EXPECTED MOSTLY EACH AFTERNOON/EVENING THROUGH MID
WEEK WITH BRIEF REDUCTIONS IN CEILINGS AND/OR VISIBILITIES.

&&

.MARINE...
TODAY AND TONIGHT...SMALL CRAFT ADVISORIES WILL REMAIN IN EFFECT
FOR ALL COASTAL WATERS OUTSIDE OF THE NEAR SHORE GEORGIA WATERS. A
TIGHT GRADIENT BETWEEN A STALLED FRONT INLAND AND ATLANTIC HIGH
PRESSURE WILL MAINTAIN A STRONG SOUTH/SOUTHWEST FLOW THROUGH TONIGHT.
WINDS IN THE ADVISORY AREA WILL BE A SOLID 15-20 KT WITH FREQUENT
GUSTS TO 25 KT AND SEAS COULD BE AS HIGH AS 4-6 FT. WINDS ALONG
THE LAND/SEA INTERFACE WILL STRENGTHEN LATE TODAY INTO TONIGHT AND
COULD APPROACH SMALL CRAFT ADVISORY CRITERIA IN CHARLESTON
HARBOR...BUT CONFIDENCE IS NOT HIGH ENOUGH TO ISSUE AN ADVISORY AT
THIS TIME.

MONDAY THROUGH FRIDAY...THE COASTAL WATERS WILL REMAIN IN BETWEEN
ATLANTIC HIGH PRESSURE TO THE EAST AND LOW PRESSURE TO THE WEST
THROUGH MID WEEK WITH HIGH PRESSURE GAINING MORE CONTROL LATER THIS
WEEK. THIS PATTERN WILL RESULT IN MOSTLY SOUTHERLY WINDS...ENHANCED
TO NEAR ADVISORY LEVELS AT TIMES DUE TO A TIGHTER THAN NORMAL
PRESSURE GRADIENT AND LOW-LEVEL JET FOR THIS TIME OF YEAR. THE
STRONGEST WINDS WILL MAINLY BE ACROSS THE SOUTH CAROLINA NEAR SHORE
WATERS AND OFFSHORE GEORGIA WATERS. SIGNIFICANT WAVE HEIGHTS WILL
ALSO BE CLOSE TO ADVISORY LEVELS IN THESE SAME AREAS INTO TUESDAY.

RIP CURRENTS...A MODERATE RISK OF RIP CURRENTS IS EXPECTED TO PERSIST
ALONG THE SOUTH CAROLINA BEACHES TODAY. WINDS AND SWELLS SHOULD
BE A BIT LESS ALONG THE GEORGIA COAST...THUS THE RIP CURRENT RISK
WILL REMAIN IN IN LOW CATEGORY THIS AFTERNOON FOR THE GEORGIA BEACHES.
