AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHARLESTON SC
216 PM EDT SAT APR 21 2012

.SYNOPSIS...
A COLD FRONT WILL APPROACH FROM THE NORTHWEST TODAY BEFORE A
STRONG LOW PRESSURE SYSTEM TRACKS OVER THE AREA OR JUST OFFSHORE
TONIGHT INTO EARLY SUNDAY. THE LOW WILL MOVE WELL TO THE NORTHEAST
LATER SUNDAY WITH HIGH PRESSURE GRADUALLY MOVING IN FROM THE WEST
THROUGH MID WEEK. A BACKDOOR COLD FRONT COULD IMPACT THE AREA
LATE IN THE WEEK.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
SHOWERS DEVELOPING ALONG COASTAL SC WITH SOME STRONG...POSSIBLY
SEVERE...STORMS FIRING ACROSS BERKELEY COUNTY IN A POCKET OF
INCREASED INSTABILITY WHERE DCAPES ARE AROUND 900 J/KG AND WET
BULB ZERO HEIGHTS ARE AROUND 9500 FT. ADDITIONAL SHOWERS/THUNDERSTORMS
DEVELOPING ACROSS SOUTHEAST GEORGIA PUSHING TOWARD THE ALTAMAHA
RIVER. EXPECT RAIN CHANCES TO INCREASE THROUGH THE REST OF THE
AFTERNOON...ALTHOUGH THE SEVERE POTENTIAL LOOKS TO REMAIN LIMITED
AS DEEPER MOISTURE ADVECTS INTO THE REGION FROM THE SW. HIGHS
SHOULD PEAK IN THE LOWER 80S AWAY FROM THE BEACHES.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH TUESDAY/...
VERY COMPLICATED FORECAST FOR TONIGHT WITH BELOW NORMAL FORECASTER
CONFIDENCE. THE AFOREMENTIONED UPPER LOW IS FORECAST TO MOVE
ACROSS THE FLORIDA PENINSULA OVERNIGHT AS THE PRIMARY SURFACE LOW
WEAKENS OVER THE EASTERN GULF AND SECONDARY CYCLOGENESIS INITIATES
SOMEWHERE OFF THE SOUTHEAST U.S. COAST. THE EXACT PATH THE UPPER
LOW TAKES AND WHERE THE SECONDARY SURFACE LOW FORMS WILL BE
CRITICAL ON HOW MUCH RAINFALL IMPACTS SOUTHEAST SOUTH SOUTH
CAROLINA AND SOUTHEAST GEORGIA. CURRENT INDICATIONS ARE THAT THE
STRONGEST UPPER DIFLUENCE AND DEEP LAYERED UVM ASSOCIATED WITH THE
UPPER LOW ITSELF WILL LIKELY REMAIN DISPLACED TO THE SOUTH AN
EAST OF THE REGION AND WITH IT THE AXIS OF HEAVIEST RAINFALL. THIS
COUPLED WITH A POSSIBLE DISRUPTION OF MOISTURE TRANSPORT FROM
WIDESPREAD CONVECTION OVER FLORIDA INTRODUCES SOME FAIRLY SIZABLE
UNKNOWNS ON EXACTLY HOW MUCH RAIN WILL FALL. 00Z TABULAR GUIDANCE
HAS ACTUALLY LOWERED RAINFALL CHANCES FROM YESTERDAY/S RUNS WHICH
ALSO MATCHES TRENDS NOTED IN THE LATEST SREF ENSEMBLE MEAN.

GIVEN THE INTRODUCTION OF SOME FAIRLY SIZABLE NEGATIVE
VARIABLES...PREFER TO REMAIN FAIRLY CONSERVATIVE WITH POPS AND
RESULTING QPF FOR THE OVERNIGHT HOURS. WILL FORECAST POPS RANGING
FROM 40-50 PERCENT WELL INLAND TO 70 PERCENT ACROSS THE COASTAL
COUNTIES. ANY MENTION OF LOCALLY HEAVY RAINFALL WILL BE REMOVED
WITH THE AXIS OF STRONGEST UPPER DIFLUENCE AND THE PRIMARY MID-
LEVEL AXIS OF THETA-E FORECAST TO REMAIN OFFSHORE. RAINFALL
AMOUNTS THROUGH SUNRISE SUNDAY WILL AVERAGE 0.25-0.75 INCH WITH
LOCALLY HIGHER AMOUNTS BEING POSSIBLE...MAINLY AT THE COAST. LOWS
WILL BOTTOM OUT IN THE LOWER-MID 60S. SURFACE BASED INSTABILITY
LOOKS QUESTIONABLE AT BEST AND WITH THE STRONGEST DYNAMICS
FORECAST TO REMAIN OFFSHORE AND WELL TO THE SOUTH THE RISK FOR
TSTMS WILL BE LOW. HOWEVER...WILL KEEP A SLIGHT CHANCE OF TSTMS IN
THE FORECAST AS AN ISOLATED TSTM OR TWO CAN NOT BE RULED OUT.

SUNDAY...A SPLIT FLOW REGIME WILL BE HIGHLIGHTED BY A SOUTHERN
STREAM SHORTWAVE TRACKING ACROSS FLORIDA AND OFF THE SOUTHEAST
COASTLINE...WHILE A DEEP UPPER TROUGH DIGS SOUTHWARD FROM THE
GREAT LAKES REGION. A SURFACE LOW ASSOCIATED WITH THE SOUTHERN
SHORTWAVE WILL ALSO LIFT ACROSS FLORIDA...DEEPENING BETWEEN THE
SOUTHEAST COASTLINE AND GULF STREAM BY MIDDAY. RAIN COVERAGE AND
DURATION DURING THE FIRST HALF OF SUNDAY WILL BE HIGHLY DEPENDENT
ON THE EXACT TRACK OF THE COASTAL LOW SYSTEM. MOST NUMERICAL MODEL
SOLUTIONS KEEP THE UPPER SHORTWAVE TO THE SOUTH AND EAST OF THE
FORECAST AREA...WHILE TRACKING THE AXIS OF THE SURFACE SYSTEM JUST
OFFSHORE AND TO THE NORTHEAST AS THE DAY PROGRESSES. THIS SCENARIO
WOULD PLACE THE BEST RAIN CHANCES ACROSS THE COASTAL COUNTIES AND
CHARLESTON TRI COUNTY REGION EARLY IN THE DAY. HOWEVER BOTH THE
00Z GFS AND NAM SOLUTIONS ALSO SUGGEST THAT A RESURGENCE OF
SHOWERS/THUNDERSTORMS COULD THEN OCCUR INLAND DURING THE AFTERNOON
HOURS...AS ENERGY WITHIN THE BASE OF THE BROAD UPPER TROUGH
SWEEPS INTO THE REGION FROM THE WEST.

INSTABILITY PARAMETERS INDICATE A BRIEF WINDOW OF OPPORTUNITY FOR
THUNDER MAINLY DURING THE EARLY AFTERNOON. HOWEVER SURFACE
INSTABILITY QUICKLY DIMINISHES BY MID TO LATE AFTERNOON...AS THE
COASTAL LOW DEEPENS AND PULLS FARTHER TO THE NORTHEAST. WIND
FIELDS DO NOT LOOK IMPRESSIVE UNTIL LATE AFTERNOON/EARLY
EVENING...WHEN THE NOSE OF AN 80 TO 90 KT UPPER LEVEL JET MOVES
INTO THE FORECAST AREA FROM THE WEST. HAVE THUS PREFERRED TO CAP
THUNDER POTENTIAL AT JUST SLIGHT CHANCE SUNDAY MORNING THROUGH MID
AFTERNOON. WRAP AROUND MOISTURE ON THE BACK SIDE OF THE COASTAL
LOW WILL MAINTAIN 30 TO 40 PERCENT POPS INTO THE LATE AFTERNOON
SUNDAY...WITH RAIN CHANCES STEADILY DECREASING FROM SOUTHWEST TO
NORTHEAST INTO THE EVENING HOURS. AS HIGH PRESSURE NUDGES INTO THE
SOUTHERN STATES BEHIND THE LIFTING COASTAL SYSTEM...DRIER AIR WILL
MOVE INTO THE FORECAST AREA AND BRING AN END TO SHOWER ACTIVITY
ACROSS ALL AREAS AFTER MIDNIGHT.

HIGH TEMPERATURES ON SUNDAY WILL BE COOLER IN THE MID TO UPPER 70S
WITHIN THICK CLOUD COVER AND VEERING LOW LEVEL WINDS. LOW
TEMPERATURES SUNDAY NIGHT WILL ALSO TREND COOLER WITHIN COLD
ADVECTION BEHIND THE DEPARTING LOW SYSTEM...FALLING INTO THE MID TO
UPPER 40S INLAND AND LOWER 50S ALONG THE COAST.

MONDAY AND TUESDAY...THE AXIS OF THE LONGWAVE UPPER TROUGH WILL
LINGER OVER THE EAST COAST ON MONDAY AND SLIP INTO THE ATLANTIC ON
TUESDAY...AS SURFACE HIGH PRESSURE BUILDS JUST TO THE SOUTH. THIS
WILL SUPPORT NOTICEABLY COOLER AND DRIER WEATHER EARLY NEXT WEEK.
HIGH TEMPERATURES WILL BE SUPPRESSED IN THE LOWER 70S BOTH MONDAY
AND TUESDAY AFTERNOONS. LOW TEMPERATURES COULD BECOME QUITE COOL
MONDAY NIGHT...FALLING TO 39 OR 40 DEGREES ACROSS FAR INLAND
ZONES. DEEP MIXING INTO A 25 TO 30 KT LOW LEVEL JET COULD ALSO
SUPPORT BREEZY CONDITIONS MONDAY AFTERNOON.

&&

.LONG TERM /TUESDAY NIGHT THROUGH FRIDAY/...
EXPECT A STEADY WARMING TREND BY MID WEEK AS THE TROUGH AXIS MOVES
FARTHER INTO THE ATLANTIC. HIGH TEMPERATURES WILL REBOUND INTO THE
UPPER 70S TO LOWER 80S BY WEDNESDAY AND LIKELY REMAIN IN THAT
RANGE INTO THE WEEKEND. LATEST NUMERICAL MODEL SOLUTIONS ARE
COMING INTO BETTER AGREEMENT INDICATING A BACKDOOR FRONT SLIPPING
TOWARD THE REGION THURSDAY AND POSSIBLY LINGERING OVER OR NEAR THE
FORECAST AREA FRIDAY. PREFER TO KEEP RAIN CHANCES BELOW 15 PERCENT
THROUGH THE EXTENDED FORECAST PERIOD THIS FAR IN ADVANCE...ESPECIALLY
CONSIDERING ONLY WEAK UPPER LEVEL SUPPORT SEEN IN MODEL SOLUTIONS
AT THIS POINT.

&&

.AVIATION /18Z SATURDAY THROUGH WEDNESDAY/...
LINGERING MVFR CEILINGS AT KCHS FOR THE NEXT FEW HOURS SHOULD
BECOME VFR THE REST OF THE AFTERNOON. KSAV SHOULD REMAIN VFR
DURING THIS TIME AS WELL ALTHOUGH CONVECTION MOVING IN FROM THE
SOUTH COULD AFFECT THE TERM LATER THIS AFTERNOON. OVERALL...EXPECT
DETERIORATING CONDITIONS THIS EVENING AS A STORM SYSTEM MOVES
NORTHEAST FROM THE GULF OF MEXICO ACROSS THE REGION...OR POSSIBLY
RE-DEVELOPS OFF THE SC/GA COASTS. EITHER WAY...CIGS WILL LOWER AND
RAIN CHANCES WILL INCREASE. BEYOND THIS AFTERNOON...INSTABILITY SEEMS
TOO LOW TO PRODUCE TS AT THE TERMS. MODEL GUIDANCE STILL SUGGESTS
THE BULK OF THE RAINFALL WILL FALL EAST AND SOUTH OF THE
TERMINALS...ALTHOUGH DEEPENING MOISTURE AND LIFT WILL LEAD TO
SHOWERS AT BOTH TERMINALS...SOME OF WHICH COULD BE HEAVY AT TIMES
LEADING TO REDUCED VSBY. IMPROVING CONDITIONS EXPECTED AFTER DAYBREAK
SUN AS THE STORM SYSTEM MOVES NORTHEAST AWAY FROM THE AREA BUT
LINGERING LOW- LEVEL MOISTURE WILL KEEP SUB-VFR CIGS AT THE TERMS
TILL AT LEAST 15Z...BUT POSSIBLY THROUGH THE END OF THE TAF
PERIOD...ESPECIALLY AT KCHS.

EXTENDED AVIATION OUTLOOK...MVFR OR LOWER CIGS/VSBYS ARE POSSIBLE
AT BOTH TERMINALS SUNDAY DUE TO SHOWERS AND THUNDERSTORMS
ASSOCIATED WITH A LOW PRESSURE SYSTEM MOVING UP THE SOUTHEAST
COASTLINE.

&&

.MARINE...
TODAY...DUE TO THE CLOCKWISE CIRCULATION AROUND THE WESTERN EDGE OF
ATLANTIC HIGH PRESSURE AND SEA BREEZE CIRCULATIONS...WINDS WILL
BECOME SE AND SOUTH AT NO MORE THAN 10 OR 15 KT. SEAS WILL BE A MIX
OF SWELL WAVES AND WIND WAVES...BUT COMBINED SEAS WILL HOLD AT 2-4
FEET.

TONIGHT...TRICKY WIND FORECAST FOR TONIGHT AS THE WIND FIELD MAY
BECOME SOMEWHAT NEBULOUS AS SECONDARY LOW PRESSURE DEVELOPS
SOMEWHERE OFF THE SOUTHEAST U.S. COAST LATE. WINDS SHOULD PICK UP
WITHIN THE 10-15 KT RANGE BY SUNRISE AS A COLD FRONT BEGINS TO
MOVE OFFSHORE IN THE WAKE OF THE LOW WITH SEAS BUILDING 2-3 FT
NEARSHORE WATER AND 4-5 FT OFFSHORE WATERS. THE RISK FOR SMALL
CRAFT ADVISORY CONDITIONS SHOULD HOLD OFF UNTIL AFTER SUNRISE
SUNDAY PER LOCAL SWAN WAVE MODEL.

SUNDAY THROUGH WEDNESDAY...THE MARINE FORECAST WILL BE HEAVILY
DEPENDENT ON THE STRENGTH AND TRACK OF A LOW SYSTEM SHIFTING FROM
THE FLORIDA PENINSULA AND OFF THE SOUTHEAST COASTLINE ON
SUNDAY...BEFORE DEPARTING TO THE NORTHEAST ON MONDAY. NORTHWEST
FLOW WILL SURGE BEHIND THE LOW SYSTEM BY SUNDAY EVENING...AS THE
PRESSURE GRADIENT TIGHTENS AND COLD ADVECTION INITIATES. SMALL
CRAFT ADVISORIES COULD BE NEEDED AS EARLY AS SUNDAY MORNING ACROSS
THE OFFSHORE WATERS...WITH ADDITIONAL ADVISORIES POSSIBLE FOR THE
NEARSHORE WATERS SUNDAY EVENING INTO MONDAY. EXPECT IMPROVING
CONDITIONS BY TUESDAY...AS THE COLD ADVECTION WANES AND SURFACE
HIGH PRESSURE BUILDS FROM THE WEST INTO MID WEEK.

RIP CURRENTS...ALTHOUGH THE RISK OF RIP CURRENTS IS MARGINAL
TODAY...GIVEN THE EXTRA TIDAL PULL FROM THE NEW MOON...ONSHORE WINDS
AND SMALL 6-9 SECOND SWELLS...WE HAVE MAINTAINED A LOW-END MODERATE
RISK FOR ALL BEACHES. THE RISK MAY REMAIN ELEVATED AGAIN ON SUNDAY
DESPITE AN OFFSHORE WIND WITH LINGERING SMALL SWELLS AND
ASTRONOMICAL INFLUENCES.
