Special Weather Statement, NWS Charleston, SC

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHARLESTON SC
401 PM EDT SAT AUG 9 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 NEXT WEEK. A COLD FRONT MAY THEN CROSS THE REGION BY
LATE NEXT WEEK.

&&

.NEAR TERM /UNTIL 6 AM SUNDAY MORNING/...
EXPECT NUMEROUS SHOWERS AND THUNDERSTORMS THIS AFTERNOON TO
DIMINISH IN INTENSITY AND COVERAGE TOWARD EVENING...ALTHOUGH SOME
CONVECTION COULD LINGER OVERNIGHT...ESPECIALLY OVER SC...GIVEN
THE STATIONARY FRONT WHICH WILL ATTEMPT TO SHIFT BACK SOUTH AND
EAST OVER THE AREA. STILL EXPECT A SLIGHT RISK OF A SEVERE STORM
ALONG WITH LOCALLY HEAVY RAINFALL/FLOODING WITH ANY OF THE
STRONGER STORMS THROUGH EARLY EVENING. WILL NEED TO WATCH THE
HEAVY RAIN TRENDS NEAR THE COAST AS WE HEAD INTO HIGH TIDE AS THIS
COULD PRESENT AN ENHANCED RISK FOR FLOODING. LOWS LIKELY TO RANGE
FROM THE LOWER TO MID 70S INLAND AND CLOSER TO 80 AT THE COAST.

&&

.SHORT TERM /6 AM SUNDAY MORNING THROUGH TUESDAY/...
SUNDAY...A RATHER WEAK AND GENERALLY ZONAL WEST TO NW FLOW ALOFT
WILL SIT ATOP A QUASI-STATIONARY FRONT SITUATED EAST-WEST ACROSS OUR
NORTHERN AND CENTRAL ZONES IN THE MORNING...BEFORE LIFTING A LITTLE
NORTH IN THE AFTERNOON...WITH THE SYNOPTIC CIRCULATIONS MASKED SOME
BY THE SEA BREEZE. EMBEDDED PERTURBATIONS WITHIN THE FLOW ALOFT AND
THE SYNOPTIC FORCING FROM THE PROXIMITY TO THE FRONT AND THE SEA
BREEZE WILL COMBINE WITH ABUNDANT MOISTURE /PWATS GREATER THAN 2
INCHES/ TO RESULT IN ANOTHER DAY WITH PLENTY OF CONVECTION. ISOLATED
TO SCATTERED CONVECTION WILL BE ONGOING IN THE MORNING...BUT THE
BULK OF THE ACTIVITY WILL AWAIT FOR CONVECTIVE TEMPS TO HIT THE MID
AND UPPER 80S TO PRODUCE GOOD COVERAGE OF SHOWERS/T-STORMS IN THE
AFTERNOON. PROBABILITIES WILL PEAK IN THE 60-70 RANGE...EXCEPT 50
PERCENT ALONG THE IMMEDIATE COAST. THE FLOW FROM 925-700 MB IS
PRACTICALLY NON-EXISTENT WHICH SUGGESTS THAT HEAVY RAINS WILL OCCUR
WHERE TRAINING AND/OR BACK-BUILDING STORMS OCCUR. FLASH FLOOD
ADVISORIES AND/OR WARNINGS ARE CERTAINLY POSSIBLE. MODERATE
INSTABILITY AND MESO-SCALE INTERACTIONS COULD TRIGGER A FEW STRONGER
STORMS...WITH A NON-ZERO RISK FOR ISOLATED SEVERE STORMS IN THE
AFTERNOON/EVENING WITH WET MICRO-BURSTS. WITH SOME INSTABILITY
REMAINING...PLENTIFUL MOISTURE AND LINGERING BOUNDARIES...CONVECTION
WILL BE SLOW TO WIND DOWN AT NIGHT. WE/LL KEEP WATCH FOR POSSIBLE
FOG/STRATUS AGAIN LATE AT NIGHT. THE DIURNAL TEMP CURVE SUNDAY WILL
BE DICTATED BY CONVECTION...BUT PRIOR TO RAIN-COOLED AIR WE LOOK FOR
AROUND 90 NORTH TO 93-94 SOUTH OF I-16. LOWER AND MIDDLE 70S WILL
SUFFICE FOR SUNDAY NIGHT.

MONDAY...WE STILL FIND THE STATIONARY FRONT ACROSS OUR SC
ZONES...WHILE A SLIGHTLY MORE PRONOUNCED SHORT WAVE ALOFT LOOKS TO
DEVELOP A WAVE OF LOW PRESSURE ON THE FRONT SOMEWHERE BETWEEN
CHARLESTON AND SAVANNAH. THIS FEATURE WILL PULL INTO THE ATLANTIC
MONDAY NIGHT AS THE FLOW ALOFT STARTS TO AMPLIFY MORE IN ADVANCE OF
A STRONGER SHORT WAVE DROPPING THROUGH THE UPPER MIDWEST. PWATS
REMAIN GREATER THAN 2 INCHES AND THE FLOW IS STILL FAIRLY
WEAK...ALTHOUGH A BIT MORE SO THAN ON SUNDAY. THIS WILL AGAIN LEAD
TO LOCALLY HEAVY RAINFALL. BOUNDARY INTERACTIONS COULD SPUR A FEW
STRONGER OR ONE OR TWO MARGINALLY SEVERE STORMS. POPS WILL AGAIN
PEAK IN THE AFTERNOON IN THE 50-60 PERCENT RANGE. WITH SLIGHTLY LESS
COVERAGE AND A LITTLE MORE WESTERLY FLOW OFF THE APPALACHIANS WE CAN
ANTICIPATE TEMPS IN THE LOWER AND MIDDLE 90S BEFORE CONVECTION
MESHES UP THE DIURNAL CURVE.

TUESDAY...A MORE AMPLIFIED PATTERN ALOFT WILL OCCUR AS A SHORT WAVE
DIGS THROUGH THE OHIO VALLEY. THE FLOW WILL BACK A LITTLE MORE
WEST-SW ALOFT AND THIS ALLOWS FOR THE SURFACE WAVE TO LIFT NORTH/NE
OF THE FORECAST AREA AS THE STATIONARY FRONT TRANSITIONS INTO A MORE
DIFFUSE COLD FRONT...STILL NEARBY. PWATS ARE STILL GREATER THAN 2
INCHES...BUT NOW THERE IS SOME BETTER WIND FIELDS AS EVIDENCED BY
20-30 KT MID LEVEL FLOW AND 30-40 KT UPPER FLOW. THIS AGAIN LEADS TO
ABOVE NORMAL POPS IN THE 40-60 PERCENTILE. THE SEVERE POTENTIAL IS
TEMPERED BY ONLY MARGINAL THERMODYNAMICS...ALTHOUGH THE HIGHER WIND
FIELDS CERTAINLY COULD GENERATE SOME STRONGER OR ISOLATED SEVERE
STORMS. TEMPS SIMILAR TO OR A DEGREE OR SO HIGHER THAN ON MONDAY.

&&

.LONG TERM /TUESDAY NIGHT THROUGH SATURDAY/...
THE FORECAST AREA WILL GENERALLY REMAIN BETWEEN A BROAD UPPER
TROUGH CENTERED TO THE NORTH AND UPPER LEVEL RIDGING SUPPRESSED
TO THE SOUTH OVER FLORIDA AND THE BAHAMAS. A WAVE OF SURFACE LOW
PRESSURE WILL BE LIFTING NORTH OFF THE NORTH CAROLINA/VIRGINIA
COASTLINE BY TUESDAY NIGHT...WITH A MORE WELL-DEFINED COLD FRONT
PROGRESSING EAST FROM THE OHIO/TENNESSEE VALLEYS IN ITS WAKE.
NOTABLY DRIER AIR WILL ACCOMPANY THE FRONT AS IT SHIFTS TOWARD
THE SOUTHEAST COAST BY THURSDAY AND POSSIBLY STALLS/DISSIPATES TO
THE EAST/SOUTHEAST FRIDAY. HAVE INDICATED HIGHEST RAIN CHANCES OF
THE EXTENDED PERIOD ON WEDNESDAY...BEFORE THE BAND OF DEEP
MOISTURE DISSIPATES OVER THE REGION AHEAD OF THE APPROACHING
FRONTAL SYSTEM. HAVE THEN TRENDED RAIN CHANCES BACK DOWN TOWARD
MORE SEASONAL 20 TO 30 PERCENT FOR THURSDAY THROUGH
SATURDAY...WITH BEST THUNDERSTORM POTENTIAL DURING THE
CLIMATOLOGICALLY FAVORED AFTERNOON TIME FRAME. EXPECT LITTLE
VARIATION IN THE HIGH TEMPERATURES EACH DAY...WITH TEMPERATURES
PEAKING IN THE LOWER 90S INLAND EACH AFTERNOON.

&&

.AVIATION /20Z SATURDAY THROUGH THURSDAY/...
NUMEROUS SHOWERS AND TSTMS EXPECTED THIS AFTERNOON WITH A STALLED
FRONT OVER THE AREA...THE SEA BREEZE...WEAK SHORTWAVE ENERGY ALOFT
AND DEEP MOISTURE. HEAVY RAINFALL AND GUSTY WINDS ARE POSSIBLE
WITH ANY OF THE STRONGER STORMS WITH SUB-IFR CONDS POSSIBLE. THERE
WILL BE A RISK FOR ADDITIONAL SHOWERS AND MAYBE A STORM OVERNIGHT AS
WELL..ESPECIALLY AT KCHS AS THE FRONT SINKS BACK SOUTHWARD.
ALSO...THERE WILL BE A RISK FOR SOME LOW CLOUDS/FOG LATE TONIGHT BUT
AT THIS POINT WE THINK THE BEST CHANCE WILL REMAIN WEST OF THE
TERMS.

EXTENDED AVIATION OUTLOOK...EXPECT SCATTERED AND MAINLY DIURNAL
SHOWERS AND THUNDERSTORMS...WITH BRIEF PERIODS OF FLIGHT
RESTRICTIONS THROUGH THURSDAY.

&&

.MARINE...
TONIGHT...NO SIGNIFICANT ISSUES EXPECTED WITH A STATIONARY FRONT
LINGERING NEARBY. WINDS MAINLY 10 KT OR LESS THROUGHOUT WITH SEAS
1-3 FT...HIGHEST OFFSHORE.

SUNDAY THROUGH MONDAY...THE QUASI-STATIONARY FRONT WILL PERSIST
OVER OR NEAR THE LOCAL WATERS...GENERATING MOSTLY GENTLE OR
MODERATE BREEZES AND SEAS LESS AT OR BELOW 3 FT THROUGH THE
PERIOD. HOWEVER...SOME STORMS THAT DEVELOP OR MOVE FROM OFF THE
MAINLAND WILL BE STRONG ENOUGH TO PRODUCE WINDS IN EXCESS OF 30 OR
40 KT...HEAVY RAINS AND FREQUENT LIGHTNING. MARINE WEATHER
STATEMENTS AND/OR SPECIAL MARINE WARNINGS MAY BECOME NECESSARY AT
TIMES. MARINERS SHOULD MAINTAIN A WEATHER WATCH...LISTENING TO
NOAA WEATHER RADIO OR APPROPRIATE VHF CHANNELS.

TUESDAY THROUGH THURSDAY...THE STATIONARY FRONT BECOMES DIFFUSE ON
TUESDAY...GIVING WAY TO 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 SE AND SOUTH...BUT BELOW
ANY ADVISORY HEADLINES. STRONGER T-STORMS WILL AGAIN PERIODICALLY
OCCUR...ALTHOUGH PERHAPS WITH LESS FREQUENCY THAN EARLIER IN THE
WEEK.

&&

.TIDES/COASTAL FLOODING...
EXPECT TIDE LEVELS TO EXCEED ADVISORY LEVELS ALONG THE LOWER SC
COAST WITH A LITTLE LESS CHANCE ALONG THE NORTHERN GA COAST.
HOWEVER...WE KEPT THE ADVISORY IN PLACE FROM 6-10 PM FOR THE
ENTIRE AREA AS HEAVY RAINFALL COULD EXACERBATE THE ISSUE AND LEAD
TO SOME FLOODING.

THE PROXIGEAN SPRING TIDE WILL OCCUR SUNDAY...AND THESE ASTRONOMICAL
INFLUENCES WILL CONTINUE TO GENERATE ELEVATED TIDES INTO EARLY NEXT
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 INTO EARLY
NEXT WEEK...ESPECIALLY ALONG THE SC COAST. 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.
