AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHARLESTON SC
121 PM EDT SUN AUG 21 2011

.SYNOPSIS...
ATLANTIC HIGH PRESSURE WILL PREVAIL OVER THE REGION THROUGH SUNDAY.
A COLD FRONT WILL APPROACH FROM THE NORTHWEST MONDAY...THEN STALL AND
EVENTUALLY DISSIPATE NEAR THE AREA THROUGH THE MIDDLE OF NEXT
WEEK. TROPICAL CYCLONE IRENE COULD IMPACT THE SOUTHEAST STATES LATE
IN THE WEEK.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
NO CHANGES MADE FOR EARLY AFTERNOON UPDATE. TEMPERATURES RISING TO
THE LOWER 90S AWAY FROM THE COAST...AND WIDELY SCATTERED
CONVECTION IS BEGINNING TO DEVELOP.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH WEDNESDAY/...
SCATTERED SHOWERS/TSTMS WILL BE ONGOING AFTER SUNSET...A FEW OF
WHICH MAY BE SEVERE. INCOMING GUIDANCE SUGGESTS ACTIVITY COULD
LINGER WELL INTO THE NIGHT AS WHAT APPEARS TO BE A LARGE OUTFLOW
BOUNDARY DROPS SOUTHEAST TOWARDS THE SAVANNAH METRO AREA. WILL
CONTINUE TO HIGHLIGHT 30-40 PERCENT POPS FOR MOST OF THE FORECAST
AREA WITH GRADUALLY DIMINISHING TO 20-30 PERCENT AFTER MIDNIGHT.
NOCTURNAL JETTING ALONG WITH ONGOING TSTM ACTIVITY WILL LIKELY
KEEP THE BOUNDARY LAYER FROM DECOUPLING WHICH HELP KEEP OVERNIGHT
TEMPERATURES SOMEWHAT ELEVATED. EXPECT LOWS FROM THE LOWER 70S
INLAND TO THE UPPER 70S/LOWER 80S AT THE COAST...ALTHOUGH TSTMS
COULD DROP TEMPERATURES BELOW THESE VALUES AT ANY TIME.

MONDAY...THE COLD FRONT WILL DESCEND INTO THE FORECAST AREA FROM
THE NORTHWEST ON MONDAY...ASSISTED BY SHORTWAVE ACTIVITY TRACKING
ALONG THE BASE OF AN UPPER LEVEL TROUGH. TIMING DIFFERENCES BETWEEN
THE GFS AND NAM ADD SOME UNCERTAINTY TO THE FORECAST...AS THE 00Z
NAM SOLUTION HAS SLIGHTLY ACCELERATED THE FRONTAL PROGRESSION.
DESPITE THE MORE RAPID MOVEMENT OF THE FRONT...THE NAM STILL
PRODUCES PRECIPITATION OVER THE REGION BY LATE IN THE DAY. WILL
THEREFORE CONTINUE TO INDICATE RAIN CHANCES IN THE 30 TO 40
PERCENT RANGE ACROSS THE FORECAST AREA BY MONDAY AFTERNOON.

ENHANCED FORCING FROM SYNOPTIC SCALE FEATURES SUGGESTS A SLIGHTLY
HIGHER POTENTIAL FOR SEVERE WEATHER COMPARED TO A TYPICAL DAY
DRIVEN ONLY BY THE SEA BREEZE AND BOUNDARY COLLISIONS. UPPER LEVEL
DYNAMICS APPEAR SOMEWHAT CONDUCIVE DUE TO THE PRESENCE OF A RATHER
DISTINCT JET ALOFT STRETCHING TOWARD THE REGION FROM THE OHIO
VALLEY...ALONG WITH AFOREMENTIONED ABUNDANT SHORTWAVE ENERGY.
CONSIDERING ENHANCEMENTS FROM THESE FEATURES...COMBINED WITH
DECENT INSTABILITY AND INCREASED FORCING FROM THE FRONT...STORM
PREDICTION CENTER HAS MAINTAINED A 5 PERCENT RISK FOR SEVERE
WEATHER ON MONDAY. DCAPE VALUES APPROACH 1500 J/KG MONDAY
AFTERNOON...SUGGESTING THAT STRONGEST STORMS COULD PRODUCE
DAMAGING WINDS. HOWEVER...REMAIN HESITANT TO ADDRESS SEVERE
WEATHER IN THE OUTLOOK AT THIS TIME DUE TO MODEL INCONSISTENCIES
REGARDING THE FRONTAL PROGRESSION.

TUESDAY...THE AXIS OF THE UPPER TROUGH WILL CONTINUE TO PUSH SOUTH
AND EAST ON TUESDAY...WHILE THE SURFACE FRONT STALLS OVER THE
FORECAST AREA. HIGH PRESSURE WILL SHIFT INTO THE MID ATLANTIC
STATES AND CAROLINAS BEHIND THE FRONT...BEFORE SLIPPING INTO THE
ATLANTIC WATERS TUESDAY NIGHT. RAIN CHANCES WILL BE MORE LIMITED
WITH DRIER AIR MOVING INTO THE FORECAST AREA...AND HAVE KEPT POPS
CAPPED BELOW 30 PERCENT. BEST PRECIPITATION POTENTIAL WILL LIKELY
BE CONFINED SOUTH OF THE SAVANNAH RIVER...WHERE MOISTURE POOLING
ALONG THE DISSIPATING FRONT COULD LOCALLY ENHANCE STORM DEVELOPMENT.

WEDNESDAY...ATLANTIC HIGH PRESSURE WILL BE THE MAIN SURFACE
FEATURE BY WEDNESDAY...AS A WEAKNESS IN THE UPPER LEVEL PATTERN
DEVELOPS ALONG THE SOUTHEAST COASTLINE. A SOLID ONSHORE FLOW WILL
HAVE DEVELOPED IN THE WAKE OF THE DISSIPATING FRONT...WHICH COULD
PUSH A BAND OF DEEP LAYER MOISTURE FROM THE COASTAL WATERS INTO
THE LAND AREAS. WILL INDICATE SOLID SHOWER/THUNDERSTORM CHANCES
AS A RESULT. IT SHOULD BE NOTED THAT FORECAST UNCERTAINTY
INCREASES QUITE A BIT BY MID WEEK...AS MEDIUM RANGE MODELS ARE
INDICATING THAT TROPICAL STORM IRENE WILL BE TRACKING
WEST/NORTHWEST ACROSS THE BAHAMAS AT THIS TIME. THE PROGRESSION OF
THIS SYSTEM COULD BEGIN TO IMPACT FORECAST DETAILS AS EARLY AS
WEDNESDAY.

EXPECT A SLIGHT COOLING TREND INTO MID WEEK WITHIN AN EAST/NORTHEAST
FLOW BEHIND THE DISSIPATING FRONT. WHILE HIGH TEMPERATURES ON
MONDAY WILL BE IN THE LOW TO MID 90S...COOLER ONSHORE FLOW COULD
KEEP HIGH TEMPERATURES DOWN IN THE UPPER 80S TO AROUND 90 TUESDAY
AND WEDNESDAY.

&&

.LONG TERM /WEDNESDAY NIGHT THROUGH SATURDAY/...
MUCH OF THE EXTENDED FORECAST WILL BE HIGHLY DEPENDENT ON THE
DEVELOPMENT AND PROGRESSION OF TROPICAL CYCLONE IRENE. ALTHOUGH
NUMERICAL MODELS HAVE BEEN FAIRLY CONSISTENT IN TRACKING THE
SYSTEM TOWARD THE FLORIDA AND/OR SOUTHEAST COAST...THERE REMAINS
CONSIDERABLE UNCERTAINTY REGARDING THE EVOLUTION OF THIS SYSTEM.
HAVE LEANED TOWARD THE SLIGHTLY MORE CONSERVATIVE SOLUTION GIVEN
BY THE ECMWF...WHICH SUGGESTS AT LEAST BREEZY CONDITIONS
DEVELOPING BY FRIDAY AND CONTINUING THROUGH THE WEEKEND. PREFER TO
REMAIN RATHER GENERIC REGARDING PRECIPITATION POTENTIAL AND HAVE
INDICATED SOLID RAIN CHANCES IN THE 30 TO 40 PERCENT RANGE THROUGH
THE LATE WEEK AND WEEKEND PERIOD. WILL FORECAST HIGH TEMPERATURES
RIGHT AROUND SEASONAL NORMALS IN THE UPPER 80S TO LOWER 90S.

IT IS RECOMMENDED THAT RESIDENTS OF SOUTHEAST SOUTH CAROLINA AND
SOUTHEAST GEORGIA CONTINUE TO MONITOR FORECASTS FROM THE NATIONAL
HURRICANE CENTER AS THE TROPICS BECOME MORE ACTIVE THIS WEEK.

&&

.AVIATION /18Z SUNDAY THROUGH THURSDAY/... VFR FORECAST THROUGH
TONIGHT. SCATTERED TSTMS ARE POSSIBLE THIS AFTERNOON AND EVENING
WHICH COULD IMPACT BOTH THE KCHS AND KSAV TERMINALS BUT CONFIDENCE
IS TOO LOW TO FORECAST A DIRECT HIT AT ONE OF THE TERMINALS. WILL
KEEP AN WATCHFUL EYE.

EXTENDED AVIATION OUTLOOK...SHOWERS AND THUNDERSTORMS COULD
BRIEFLY REDUCE VSBYS AND/OR CIGS EACH AFTERNOON/EVENING THIS
WEEK. BREEZY CONDITIONS ARE POSSIBLE LATER IN THE WEEK CONSIDERING
POTENTIAL IMPACTS FROM TROPICAL CYCLONE IRENE.

&&

.MARINE...
I MADE AN ADJUSTMENT THIS MORNING TO THE GRIDS AND FORECASTS TO
ACCOUNT FOR MORE WIDESPREAD COVERAGE OF CONVECTION AND ASSOCIATED
WINDS THIS MORNING. AS THE CONVECTION DECREASES...WE WILL GO BACK
TO A RELATIVELY LIGHT SOUTHERLY FLOW REGIME WITH THE WATERS
POSITIONED ALONG THE WESTERN FRINGES OF ATLANTIC HIGH PRESSURE.
SOME SEA BREEZE INFLUENCES ARE LIKELY ALONG THE LAND/SEA INTERFACE
AS WELL AS THE CHARLESTON HARBOR...BUT BOTH WINDS AND SEAS ARE
EXPECTED TO REMAIN BELOW FLAG THRESHOLDS. SEAS WILL REMAIN IN THE
2-4 FT RANGE AND BE COMPOSED OF 2 FT 7-9 SECOND SOUTHEAST SWELL.

A MODEST NOCTURNAL LOW-LEVEL JET WILL DEVELOP TONIGHT WHICH WILL
RESULT IN SURFACE WINDS INCREASING TO 15-20 KT OUTSIDE OF THE
CHARLESTON HARBOR. SEAS WILL REMAIN 2-4 FT...ALTHOUGH THEY WILL
INCREASE A BIT OVER THE NEARSHORE WATERS OVERNIGHT...ESPECIALLY IN
THE CHARLESTON COUNTY COASTAL WATERS.

A COLD FRONT WILL DESCEND INTO THE COASTAL WATERS LATE MONDAY...
STALLING AND DISSIPATING IN THE VICINITY BY TUESDAY. MARINERS ARE
ADVISED THAT SHOULD SOME ORGANIZED CONVECTION DEVELOP OVER LAND
MONDAY IN ASSOCIATION WITH THE COLD FRONT AND ASSOCIATED SYNOPTIC
SCALE DYNAMICS...WESTERLY STEERING FLOW COULD ALLOW STRONG TO
SEVERE STORMS TO IMPACT THE MARINE AREA. DAMAGING WINDS AND
FREQUENT LIGHTNING STRIKES ARE POSSIBLE.

A SOLID ONSHORE FLOW WILL DEVELOP LATE TUESDAY THROUGH THURSDAY IN
THE WAKE OF THE DISSIPATING FRONT...AS SURFACE HIGH PRESSURE TO
THE NORTH SHIFTS INTO THE ATLANTIC. WIND SPEEDS WILL GENERALLY BE
LIMITED TO 15 KT OR LESS WITH SEAS 3 TO 5 FT THROUGH WEDNESDAY.

TROPICAL CYCLONE IRENE CONTINUES TO BE A CONCERN FOR THE LATE WEEK
PERIOD...WITH NUMERICAL MODELS CONSISTENT IN TRACKING THE SYSTEM
WEST/NORTHWEST THROUGH THE BAHAMAS AND POTENTIALLY TOWARD THE
FLORIDA AND/OR SOUTHEAST COAST. FOLLOWING MODEL TRENDS...HAVE
INTRODUCED STEADILY INCREASING EAST WINDS FROM SOUTH TO NORTH AS
EARLY AS THURSDAY. IN ADDITION...SEA HEIGHTS WILL LIKELY BE
RESPONDING TO THE SYSTEM AS EARLY AS WEDNESDAY NIGHT INTO
THURSDAY. HAVE THUS INDICATED SEAS BUILDING TO 5 TO 6 FT IN THE
OUTER WATERS BY LATE THURSDAY. PLEASE REFER TO THE LATEST
INFORMATION FROM THE NATIONAL HURRICANE CENTER FOR UPDATES ON THE
TROPICAL FORECAST.

RIP CURRENTS...SWELLS FROM IRENE COULD ARRIVE AS EARLY AS MID-
WEEK. THIS WILL RESULT IN AN INCREASED RISK FOR RIP CURRENTS WHICH
WILL BE ADDRESSED IN THE HAZARDOUS WEATHER OUTLOOK.
