AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHARLESTON SC
151 PM EDT SUN AUG 10 2014
.SYNOPSIS...
A STATIONARY FRONT WITH UNSETTLED WEATHER WILL REMAIN OVER OR
NEAR THE AREA INTO MONDAY...THEN BECOME ILL-DEFINED DURING THE
MIDDLE OF THE WEEK. A COLD FRONT MAY THEN CROSS THE REGION BY LATE
WEEK.
&&
.NEAR TERM /UNTIL 6 PM THIS EVENING/...
SHOWERS AND THUNDERSTORMS INCREASING IN COVERAGE AROUND CHARLESTON
AS OF EARLY AFTERNOON WITH MOST OTHER AREAS DRY. ABUNDANT CLOUD
COVER TODAY HAS HELD DOWN TEMPERATURES A BIT WHICH HAS KEPT
INSTABILITY LOWER. HOWEVER...WE STILL DO EXPECT MORE CONVECTIVE COVERAGE
THROUGH THE AFTERNOON AS THE SEA BREEZE STRENGTHENS A BIT AND
PUSHES INLAND. THE MAIN CONCERN REVOLVES AROUND HEAVY RAIN AND
FLOODING POTENTIAL. CANNOT RULE OUT AN ISOLATED SEVERE STORM AS
WELL WITH DAMAGING WINDS. SEE THE HYDROLOGY SECTION BELOW FOR
ADDITIONAL INFO ON THE POTENTIAL FOR FLASH FLOODING AND QPF
AMOUNTS.
&&
.SHORT TERM /6 PM THIS EVENING THROUGH WEDNESDAY/...
TONIGHT...WDSPRD SHWRS/TSTMS WL BE ONGOING AFTER SUNSET WITH HIGH
RES GUIDANCE SUGGESTING A LARGE CONVECTIVE CLUSTER COULD MOVE S
OUT OF SRN SC INTO COASTAL SE GA. THIS IS CONCERNING AS THIS COULD
IMPACT THE SAV METRO AREA DURING ALREADY HIGH ASTRONOMICAL
TIDES...THUS ENHANCING THE RISK FOR SIG FLASH FLOODING. ADJUSTED
GRIDDED POPS TO SHOW THE HIGHEST POPS ACROSS THE S WITH HIGHER
POPS SHIFTING BACK N OVRNGT BACK NEAR THE VCNTY OF THE STNRY FNT...
WHICH SHOULD BE LOCATED ACROSS SRN SC. IT WL CONT BE QUITE MUGGY
WITH LOWS IN THE THE MID-UPR 70S.
MONDAY...THE DAY WILL BEGIN WITH LITTLE OVERALL CHANGE IN THE
PATTERN AT THE SURFACE AND ALOFT. A NEARLY STATIONARY FRONT WILL
LINGER OVER THE SOUTH CAROLINA ZONES...WHILE A FAIRLY WEAK TROUGH
PATTERN PREVAILS ALOFT. SHORTWAVE ENERGY FAR TO THE NORTH...DIVING
INTO THE GREAT LAKES AND OHIO VALLEY REGIONS...WILL EXTEND THE
UPPER TROUGH DOWN TOWARD THE EAST COAST LATE IN THE DAY. A WAVE OF
SURFACE LOW PRESSURE WILL TAKE SHAPE ALONG THE MEANDERING FRONT IN
RESPONSE TO THE GRADUALLY AMPLIFYING PATTERN...EVENTUALLY SHIFTING
NORTHEAST UP THE CAROLINA COASTLINE DOWNSTREAM OF THE TROUGH AXIS
OVERNIGHT. THE CONTINUED PRESENCE OF THE BOUNDARY AND SURFACE WAVE
WILL PROVIDE PERSISTENT FORCING FOR ASCENT...AND WHEN COMBINED
WITH SHORTWAVE ENERGY PROGRESSING THROUGH THE REGION...WILL
MAINTAIN DEEP MOISTURE ACROSS THE SOUTHEAST STATES. NUMERICAL
MODELS ARE IN GOOD AGREEMENT INDICATING SCATTERED TO NUMEROUS
THUNDERSTORM DEVELOPMENT DURING THE DAYTIME HOURS...BEFORE
PRECIPITATION COVERAGE DIMINISHES FROM WEST TO EAST OVERNIGHT.
PRECIPITABLE WATER VALUES WILL STILL BE ABOVE 2.25 INCHES ACROSS
THE FORECAST AREA MONDAY AFTERNOON...AND WITH STORM MOTIONS
LESS THAN 10 KT...HEAVY DOWNPOURS AND LOCALIZED FLOODING AGAIN
APPEARS POSSIBLE. THICK CLOUD COVER AND DECENT RAIN COVERAGE WILL
KEEP HIGH TEMPERATURES NEAR OR JUST A DEGREE BELOW SEASONAL
NORMALS...RANGING FROM AROUND 89 DEGREES NORTH TO 92 SOUTH TO THE
ALTAMAHA RIVER.
TUESDAY...THE AXIS OF THE AMPLIFYING UPPER TROUGH WILL EXTEND DOWN
THE EAST COAST...WITH ASSOCIATED SHORTWAVE ENERGY PICKING UP THE
SURFACE LOW AND DRIVING IT NORTHEAST AND OFF THE MID ATLANTIC
COAST BY THE NIGHTTIME HOURS. SUFFICIENT DEEP MOISTURE AND
CONVERGENCE FROM THE SYNOPTIC SCALE FEATURES WILL PROVIDE THE
NECESSARY INGREDIENTS TO ONCE AGAIN SUPPORT RAIN CHANCES IN THE 50
PERCENT RANGE...ESPECIALLY ALONG AND TO THE SOUTH OF THE
TRAILING/WEAK FRONT. STORM MOTIONS ARE NOTABLY FASTER THAN THE
PREVIOUS DAY...HOWEVER PRECIPITABLE WATER VALUES WILL STILL BE
ABOVE 2.0 INCHES. THUS...HEAVY DOWNPOURS AND ISOLATED LOCALIZED
FLOODING ARE STILL POSSIBLE...ESPECIALLY WHERE BOUNDARY
INTERACTIONS OCCUR. TEMPERATURES WILL REACH THE LOWER 90S AWAY
FROM THE LOCALLY COOLER COASTLINE UNDER MOSTLY CLOUDY SKIES. BEST
SHOWER/THUNDERSTORM COVERAGE WILL SHIFT TO THE COASTAL AREAS AND
NEARBY WATERS OVERNIGHT.
WEDNESDAY...THE STRENGTHENING SURFACE LOW WILL HAVE LIFTED WELL TO
THE NORTHEAST OF THE AREA BY MID WEEK...WITH A DIFFUSE BOUNDARY
AND SURFACE TROUGH LINGERING ALONG THE COAST IN ITS WAKE. DRIER
HIGH PRESSURE WILL STRUGGLE TO MAKE SIGNIFICANT PROGRESS TOWARD
THE SOUTHEAST COAST FROM THE OHIO AND TENNESSEE VALLEYS...ALLOWING
A REMNANT BAND OF THE DEEP MOISTURE TO PERSIST ACROSS COASTAL AND
SOUTHERN COUNTIES. WILL TREND RAIN CHANCES DOWNWARD COMPARED TO
PREVIOUS DAYS DUE TO THE WEAKENING SYNOPTIC FEATURES...YET
MAINTAIN SOLID CHANCE POPS IN THE 30 TO 40 PERCENT RANGE DURING
THE DAYTIME HOURS. AS WITH PREVIOUS DAYS...THUNDERSTORM COVERAGE
WILL DIMINISH FROM WEST TO EAST DURING THE EVENING AND NIGHTTIME
PERIODS. HIGH TEMPERATURES WILL REACH THE LOWER 90S
INLAND...WITHIN A DEGREE OR TWO OF SEASONAL NORMALS FOR EARLY/MID
AUGUST.
&&
.LONG TERM /WEDNESDAY NIGHT THROUGH SATURDAY/...
THE FORECAST AREA WILL GENERALLY REMAIN BETWEEN A BROAD UPPER
TROUGH STRETCHING DOWN MUCH OF THE EASTERN UNITED STATES AND AN
UPPER RIDGE SUPPRESSED WELL TO THE SOUTH OVER FLORIDA AND
EVENTUALLY THE GULF OF MEXICO. A MORE WELL-DEFINED COLD FRONT
REPRESENTING THE LEADING EDGE OF DRIER HIGH PRESSURE WILL SHIFT
TOWARD THE SOUTHEAST STATES BY THURSDAY...POSSIBLY STALLING TO THE
EAST/SOUTHEAST FRIDAY. ALTHOUGH THE SURFACE HIGH WILL BE WEAKENING
AS IT SHIFTS INTO THE AREA LATE THIS WEEK...EXPECT IT TO PROVIDE
SUFFICIENT DRIER AIR TO SUPPORT A MORE SEASONAL CONVECTIVE
COVERAGE SCENARIO THROUGH THE WEEKEND. HAVE THUS INDICATED RAIN
CHANCES BACK TO THE SLIGHT CHANCE TO LOW CHANCE RANGE DURING THE
CLIMATOLOGICALLY FAVORED AFTERNOON HOURS EACH DAY FROM THURSDAY
THROUGH SUNDAY. DEWPOINTS WILL DECREASE A BIT DURING THE EXTENDED
PERIOD...HOWEVER THERE WILL BE LITTLE NOTABLE CHANGE IN THE
OVERALL HIGH TEMPERATURE RANGE. TEMPERATURES WILL PEAK IN THE
LOWER 90S INLAND EACH AFTERNOON.
&&
.AVIATION /17Z SUNDAY THROUGH THURSDAY/...
SIMILAR PATTERN COMPARED TO YESTERDAY WILL SUPPORT WIDESPREAD
SHOWERS AND THUNDERSTORMS OVER THE AREA TODAY...STARTING NEAR
KCHS AND THEN AFFECTING KSAV BY ABOUT 20Z. BEST CHANCES WILL COME
PRIOR TO 00Z BUT CANNOT RULE OUT SOME IMPACTS AFTER THAT AND POSSIBLY
EVEN OVERNIGHT. TOWARD DAYBREAK LOW CLOUDS AND FOG LOOK TO
DEVELOP...PROBABLY STAYING MVFR...BUT MAYBE MORE PREVAILING AND
LASTING LONGER THAN THE 18Z TAFS SUGGEST.
EXTENDED AVIATION OUTLOOK...EXPECT SCATTERED AND MAINLY DIURNAL
SHOWERS AND THUNDERSTORMS...WITH BRIEF PERIODS OF FLIGHT
RESTRICTIONS THROUGH THURSDAY.
&&
.MARINE...
TODAY AND TONIGHT...LGT WND FIELDS WL PERSIST AS A STNRY FNT CONTS
TO MEANDER ACROSS THE SC WTRS. SLGTLY HIGHER WNDS WL BE FOUND
ACROSS THE GA WTRS...BUT BOTH WNDS AND SEAS WL REMAIN WELL BLO ANY
ADV THRESHOLDS. A FEW STG TSTMS WL BE PSBL THROUGH TNGT WHICH MAY
REQUIRE SPECIAL MARINE WRNGS. THIS WL BE ADDRESSED IN THE
HAZARDOUS WX OTLK.
MONDAY AND TUESDAY...A MEANDERING WEAK FRONT WILL PERSIST OVER OR
NEAR THE MARINE ZONES THROUGH THE EARLY WEEK PERIOD...AS A WAVE OF
LOW PRESSURE LIFTS TO THE NORTHEAST AND OFF THE MID ATLANTIC
COAST. EXPECT WIND SPEEDS TO REMAIN 15 KT OR LESS AND SEAS
GENERALLY 2 TO 4 FT. SCATTERED TO NUMEROUS THUNDERSTORMS ARE
POSSIBLE EACH DAY...AND SOME STORMS THAT DEVELOP OR MOVE OFFSHORE
FROM LAND AREAS COULD BECOME STRONG ENOUGH TO PRODUCE WINDS IN
EXCESS OF 30 OR 40 KT...HEAVY RAIN AND FREQUENT LIGHTNING. MARINE
WEATHER STATEMENTS AND/OR SPECIAL MARINE WARNINGS MAY BECOME
NECESSARY AT TIMES.
WEDNESDAY THROUGH THURSDAY...THE STATIONARY FRONT BECOMES DIFFUSE
BY MID WEEK AHEAD OF A COLD FRONT BY LATE IN THE PERIOD. THERE
WILL BE SOME TIGHTENING OF THE GRADIENT BETWEEN THE UPSTREAM FRONT
AND THE SUB-TROPICAL ATLANTIC RIDGE TO THE SOUTH/SOUTHEAST...YET
MARINE CONDITIONS WILL REMAIN BELOW ANY ADVISORY HEADLINES.
STRONGER THUNDERSTORMS WILL AGAIN PERIODICALLY OCCUR...ALTHOUGH
PERHAPS WITH LESS FREQUENCY THAN EARLIER IN THE WEEK.
&&
.HYDROLOGY...
SYNOPTIC AND MESOSCALE ATMOSPHERIC CONDS FAVOR ANOTHER ROUND OF HVY
RNFL...MAINLY THIS AFTERNOON BUT POSSIBLY OVERNIGHT AS WELL NEAR
THE COAST. MANY AREAS...ESP ACROSS THE CHARLESTON TRI- COUNTY
AREA...SAW UPWARDS OF 2-4 INCHES WITH ISOLD AMOUNTS OF 6-10 INCHES
WITH SIGNIFICANT FLASH FLOODING NOTED IN DWTN CHARLESTON PRIOR TO
THE ONSET OF HIGH ASTRONOMICAL TIDES. SIGNIFICANT URBAN FLOODING
WAS ALSO OBSERVED IN THE BEAUFORT AND SAVANNAH METRO AREAS AS
WELL. WITH GROUNDS ALREADY SATURATED FROM RECENT HVY RAINS...1-HR
AND 3-HR FLASH FLOOD GUIDANCE VALUES HAVE DROPPED CONSIDERABLY
OVER THE PAST 24 HRS. WITH THE ENVIRON SUPPORTIVE OF EFFICIENT
RNFL...THESE VALUES COULD BE EASILY SURPASSED WHERE THE HEAVIER
CONVECTIVE CONGLOMERATES FORM. COMPLICATING MATTERS IS THAT SOME
OF THE HIGH RES MODELS SUGGEST TSTMS WITH TORRENTIAL RAINS COULD
FALL PRIOR TO AND/OR DURING HIGH TIDE...WHERE TIDE LEVELS ARE
ALREADY RUNNING VRY HIGH DUE TO ASTRONOMICAL INFLUENCES. THIS WL
RESULT IN AN ENHANCED RISK FOR FLASH FLOODING ACROSS THE COASTAL
COUNTIES AND ESPECIALLY IN THE CHARLESTON AND SAVANNAH METRO
AREAS. XPCT GENERAL RNFL AMOUNTS OF 2-4 INCHES THROUGH TNGT WITH
ISOLD AMOUNTS POTENTIALLY EXCEEDING 6-8 INCHES.
&&
.TIDES/COASTAL FLOODING...
ANOTHER ROUND OF COASTAL FLOODING IS LIKELY AGAIN TNGT. CURRENT
AND FCST TIDAL DEPARTURES SUGGEST TIDE LEVELS WL BREACH MODERATE
FLOOD THRESHOLDS ALONG THE LWR SC COAST AND SHALLOW COASTAL
FLOODING THRESHOLDS FOR THE UPR GA COAST. XPCT TIDES OF 7.4-7.7 FT
MLLW IN THE CHARLESTON HARBOR WITH 9.2 TO 9.5 FT MLLW AT FT
PULASKI. SIMILAR TO SATURDAY...HVY RAINS COULD FALL AROUND/NEAR
THE TIME OF HIGH TIDE WHICH WL ONLY EXACERBATE ENHANCE THE FLOOD
IMPACT. A COASTAL FLOOD ADV WL BE ISSUED FOR ALL COASTAL ZONES...
INCLUDING TIDAL BERKELEY...FROM 7PM-MIDNIGHT.
THE PROXIGEAN SPRING TIDE WILL OCCUR TDA AND THESE ASTRONOMICAL
INFLUENCES WILL CONTINUE TO GENERATE ELEVATED TIDES INTO EARLY
THIS WEEK. SINCE ONLY SMALL DEPARTURES ARE NEEDED ABOVE THE
PREDICTED ASTRONOMICAL TIDE VALUES TO RESULT IN AT LEAST SHALLOW
COASTAL FLOODING...THIS WILL LIKELY BOOST TIDE LEVELS ABOVE
CRITICAL THRESHOLDS THROUGH MONDAY OR TUESDAY. THE BEST CHANCE FOR
COASTAL FLOOD ADVISORIES WOULD BE DURING THE EVENING HIGH TIDES.
SHOULD HEAVY RAIN OCCUR AROUND THE TIMES OF THE ELEVATED HIGH
TIDES...RUNOFF WILL BE INHIBITED AND MORE SIGNIFICANT FLOODING
COULD OCCUR WITHIN COASTAL COMMUNITIES.
&&
.EQUIPMENT...
THE CHARLESTON SC WSR-88D /KCLX/ REMAINS OUT OF SERVICE DUE TO A
SIGNIFICANT MECHANICAL FAILURE. THE CURRENT ESTIMATE HAS THE RADAR
RETURNING TO SERVICE BETWEEN AUGUST 21 AND 25.
