AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHARLESTON SC
744 PM EDT MON MAY 5 2008

.SYNOPSIS...
WEAK LOW PRESSURE WILL SHIFT OFF THE COAST OVERNIGHT. HIGH PRESSURE
WILL BUILD OVER THE AREA FOR TUESDAY THROUGH THURSDAY. A COLD
FRONT WILL APPROACH FROM THE NORTHWEST FRIDAY...STALL NORTH OF THE
AREA OVER THE WEEKEND...FOLLOWED BY ANOTHER COLD FRONT FOR EARLY
NEXT WEEK.

&&

.NEAR TERM /UNTIL 6 AM TUESDAY MORNING/...
SCATTERED SHOWERS CONTINUE TO MOVE SOUTHEAST TOWARD BERKELEY AND
DORCHESTER COUNTIES THIS EVENING IN ASSOCIATION WITH A SHRINKING
POOL OF SURFACE-BASED INSTABILITY AND HIGHER DEWPOINTS IN THE
LOWER 60S. LOW-LEVEL MOISTURE WILL DECREASE THROUGH THE EVENING
HOURS AS THE WEAK SURFACE LOW PUSHES FARTHER OFF THE COAST AND DRY
ADVECTION COMMENCES IN ITS WAKE. ALSO...AS TEMPERATURES COOL WITH
THE LOSS OF DAYTIME HEATING...PARCEL BUOYANCY WILL QUICKLY
DIMINISH. HOWEVER...ENOUGH RESIDUAL SMALL-SCALE BOUNDARIES AND
POOLED MOISTURE EXIST TO KEEP A FEW SHOWERS GOING LATER INTO THE
EVENING THAN A TYPICAL SUMMER DAY. WILL MAINTAIN SLIGHT CHANCE OF
SHOWERS AND STORMS OVER FAR NORTHERN AREAS UNTIL 11 PM.

OVERNIGHT...AS THE SURFACE BOUNDARY FOLLOWS THE SURFACE LOW SOUTH...
NE FLOW MAY PUSH LOW CLOUDS AND FOG INTO AT LEAST NORTHERN
COUNTIES OF THE FORECAST AREA. PATCHY RADIATION FOG WILL SUFFICE
ELSEWHERE.

&&

.SHORT TERM /6 AM TUESDAY MORNING THROUGH 6 PM TUESDAY/...
HIGH PRESSURE WILL BUILD DOWN THE COAST AND INTO THE FORECAST AREA
TUESDAY...PROVIDING MOSTLY SUNNY CONDITIONS. A SEA BREEZE BOUNDARY
WILL SET UP NEAR THE COAST IN THE AFTERNOON...AND THERE EXISTS A
VERY LOW CHANCE FOR A BRIEF/ISOLATED DIURNAL SHOWER/THUNDERSTORM
IN THIS AREA...TOO LOW TO JUSTIFY ANY PRECIPITATION IN THE
FORECAST.

&&

.LONG TERM /TUESDAY NIGHT THROUGH MONDAY/...
SFC HIGH PRES WILL CENTER ITSELF OVER THE AREA TUE NIGHT INTO WED
WHILE THE UPR LEVEL RIDGE AXIS LAGS BEHIND. THIS HIGH PRES
COMBINATION WILL GRADUALLY SHIFT E ACROSS THE AREA THROUGH THU WHILE
A COMPACT UPR LEVEL LOW OVER THE SOUTHWESTERN STATES SHIFTS ENE
THROUGH THE MID MISS AND OHIO RIVER VALLEYS TO THE MID ATLC STATES.
THE SFC LOW PRES ASSOCIATED WITH THIS UPPER DISTURBANCE WILL SHIFT
OFFSHORE FRI EVE BUT ENOUGH ZONAL FLOW OVER THE SOUTHEAST STATES
WILL PREVENT MUCH SWD PROGRESS WITH THE COLD FRONT OF THIS SYSTEM.
PER GFS/ECMWF/GEM PROGS...THE E-W ORIENTED FRONT LOOKS TO STALL OUT
N OF THE CHS CWFA SAT THEN LIFT BACK N AS A WARM FRONT ON SUN. THE
APPROACH AND NEARBY PROXIMITY OF THE FRONT WILL ALLOW FOR 20/30 POPS
THU INTO FRI. A NORTHERN STREAM AREA OF LOW PRES WILL THEN DROP
THROUGH THE NORTHERN PLAINS AND GREAT LAKES SUN-MON...HELPING PUSH A
STRONGER AND MORE TRADITIONAL COLD FRONT THROUGH THE AREA ON MON. OF
COURSE...THERE IS MUCH UNCERTAINTY ON HOW THE END OF THE WEEK AND
WEEKEND SCENARIO WILL LOOK SO WILL NOT HAVE POPS ANY HIGHER THAN 20
SUN-MON.

TEMPS OVERALL WILL REMAIN WARM THROUGH THE REST OF THE WEEK INTO THE
WEEKEND...WITH MAX TEMPS GENERALLY IN THE MID 80S AND LOWS AROUND
60. THERE IS THE POSSIBILITY THAT MAX TEMPS COULD REACH THE UPPER
80S TO AROUND 90...ESPECIALLY S OF THE SAVANNAH RIVER...ON FRI AHEAD
OF THE STALLED FRONT AND ON THE BACKSIDE OF THE DEPARTING DEEP RIDGE.

&&

.AVIATION /00Z TUESDAY THROUGH SATURDAY/...
MAIN CONCERN TONIGHT IS LOW CLOUDS AND FOG DEVELOPING IN THE WAKE
OF A SURFACE LOW WITH NORTHEAST FLOW STARTING UP A BIT LATER
TONIGHT. NUMERICAL GUIDANCE IS NOT PICKING UP ON ANY LOW CLOUDS
HOWEVER MODEL SOUNDINGS AND CLIMATOLOGY INDICATE A GOOD CHANCE
THAT IFR CEILINGS WILL IMPACT CHS TERMINAL LATE. PATCHY FOG ALSO A
POSSIBILITY BUT DO NOT EXPECT THIS TO BE AS SIGNIFICANT GIVEN
BOUNDARY LAYER WINDS OF 5-8 KTS. DO NOT THINK ENOUGH LOW-LEVEL
MOISTURE WILL MAKE IT TO SAV TO PRODUCE A BKN CEILING...THUS
PAINTED SOME SCT 600 FT CEILINGS AFTER 10Z. WINDS COULD BE BRIEFLY
GUSTY ON TUE ESPECIALLY WHEN THE SEABREEZE DEVELOPS MIDDAY.

EXTENDED AVIATION OUTLOOK...
MVFR VISIBILITY POSSIBLE EARLY WED MORNING IN GROUND FOG. ISOLATED
SHOWERS AND STORMS ALONG A STALLING COLD FRONT MAY PRODUCE
OCCASIONAL MVFR-IFR CONDITIONS THU AFTERNOON THROUGH SAT.

&&

.MARINE...
WINDS AND SEAS WILL REMAIN BELOW SMALL CRAFT ADVISORY THRESHOLDS
THROUGH TUESDAY. A SURFACE LOW WILL DRIFT S/SE ACROSS THE COASTAL
TONIGHT...PULLING A WEAK COLD FRONT THROUGH THE COASTAL WATERS. IN
THE WAKE OF THIS FRONT...WIND DIRECTION WILL SHIFT TO THE
NORTHEAST TONIGHT...AND A TIGHTENING PRESSURE GRADIENT BETWEEN THE
DEPARTING SURFACE WAVE AND HIGH PRESSURE BUILDING IN FROM THE
NORTHWEST COULD ALLOW WINDS TO SURGE DURING THE PRE-DAWN HOURS.
SPEEDS ARE STILL EXPECTED TO REMAIN AT OR BELOW 20 KT...WITH SEAS
2 TO 3 FT NEARSHORE AND 3 TO 4 FEET OFFSHORE...PERHAPS BRIEFLY AS
HIGH AS 5 FT TUESDAY MORNING NEAR 60 NM EAST OF THE SE GA COAST.

TUESDAY...THE SEA BREEZE WILL MODIFY THE NE SYNOPTIC FLOW DURING
THE AFTERNOON...TURNING THE WINDS TOWARD THE E/SE NEAR THE COAST.
IN ALL AREAS...WINDS SHOULD REMAIN BELOW SCA INTENSITY.

BENIGN CONDS EXPECTED FOR TUE NIGHT THROUGH WED NIGHT AS HIGH PRES
SLIDES OVER AND TO THE E OF THE CHS MARINE AREA. S WINDS INCREASE
THU-FRI AS THE PRES GRADIENT TIGHTENS BETWEEN STALLED ATLC HIGH PRES
AND AN INCOMING COLD FRONT FROM THE NW. WINDS LOOK TO EXCEED 20 KT
FOR THE NRN SC NEARSHORE WATERS AND THE OUTER GA WATERS...AND
POSSIBLY CHAS HARBOR...WITH THE STRONG LAND/SEA INTERFACE TEMP
DIFFERENCE AND DEEP MIXING ANTICIPATED ALONG WITH THE STRONG PRES
GRADIENT. ALONG WITH THE ELEVATED WINDS...SEAS MAY EXCEED 6 FT FOR
BOTH AMZ350-374. THE COLD FRONT MAY DIP S OF THE SANTEE RIVER FRI
NIGHT INTO SAT...OTHERWISE IT WILL STALL N OF THE WATERS THROUGH THE
WEEKEND THEN LIFT BACK N AS A COLD FRONT SUN INTO MON AHEAD OF
ANOTHER COLD FRONT. CONDS MAY RETURN TO SCA LEVELS MON AHEAD OF THE
NEXT COLD FRONT...THEN SETTLE BACK DOWN TO BENIGN LEVELS.

&&

.TIDES/COASTAL FLOODING...
BASED ON TIDE DEPARTURES 3/10 TO 4/10 OF A FOOT ABOVE EXPECTED
VALUES WITH THE LATE MORNING HIGH TIDE...AND GIVEN EVENING FORECAST
TIDE LEVELS OF 6.9 FT MLLW ON CHS HARBOR AND 8.9 FT MLLW AT FT
PULASKI...WILL CONTINUE THE ONGOING COASTAL FLOOD ADVISORY FOR ALL
COASTAL COUNTIES VALID 7-11 PM THIS EVENING.

WILL CONTINUE TO MONITOR TIDES DURING THE NEXT COUPLE OF DAYS...WITH
THE PERIGEAN SPRING TIDES TO CONTINUE. IF WATER LEVELS EVEN SLIGHTLY
EXCEED EXPECTED HIGH TIDE LEVELS TUESDAY AND WEDNESDAY EVENING...
ADDITIONAL COASTAL FLOOD ADVISORIES MAY BE REQUIRED.
