Special Weather Statement, NWS Charleston, SC

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHARLESTON SC
130 PM EDT MON APR 29 2013

.SYNOPSIS...
A DISTURBANCE ALOFT WILL MOVE THROUGH THE REGION TODAY...BRINGING
WITH IT UNSETTLED WEATHER. A WAVE OF WEAK LOW PRESSURE WILL FORM OFF
THE SE COAST LATE TONIGHT. A PERSISTENT PATTERN FEATURING A STRONG
WEDGE OF HIGH PRESSURE EAST OF THE APPALACHIANS AND BROAD LOW
PRESSURE SOUTH OF THE REGION WILL PREVAIL INTO NEXT WEEKEND.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
THE FORECAST IS ON TRACK WITH STRONG TSTMS ALREADY DEVELOPING NEAR
THE SAVANNAH RIVER. INCREASED TEMPERATURES A FEW DEGS PER GOING
TRENDS WITH A FEW LOCALES LIKELY SURPASSING 80 BEFORE TSTMS COOL
THINGS OFF. STILL WATCHING FOR A FEW SEVERE TSTMS TO DEVELOP OVER
THE NEXT FEW HRS.

A WARM AND MOIST ATMOSPHERE IS IN PLACE THIS MORNING AS NOTED IN
THE 29/12Z CHS RAOB. PWATS ARE UP WELL ABOVE 1.4 INCHES WITH
DEWPOINTS IN THE MID-UPPER 60S. DEEP LAYERED MOISTURE WILL
CONTINUE TO INCREASE TODAY AHEAD OF A WELL DEFINED SHORTWAVE
MOVING ACROSS WEST-CENTRAL GEORGIA. THIS FEATURE IS EXPECTED TO
TRAVERSE THE CSRA AND SOUTHERN SOUTH CAROLINA LATER THIS
AFTERNOON AS TEMPERATURES BREACH CONVECTIVE THRESHOLDS IN THE
LOWER-MID 70S. MODIFIED SOUNDINGS YIELD MODEST INSTABILITY WITH
MAXIMUM SBCAPES 1500-2000 J/KG WITH LIFTED INDICES AS LOW AS -5 TO
-6C. THIS COUPLED WITH INCREASING FORCING AHEAD OF THE
AFOREMENTIONED SHORTWAVE WILL YIELD QUITE A BIT OF CONVECTION BY
MID AFTERNOON. ALL OF THE MESOSCALE MODELS INCLUDING THE LATEST
H3R AND NSSL WRF SUPPORT A FAIRLY WIDESPREAD SWATH OF SHOWERS AND
TSTMS BEGINNING AS EARLY AS 1 PM TO 2 PM...MOST LIKELY WITHIN AN
AREA OF ENHANCED LOW-LEVEL CONVERGENCE ALONG THE INLAND MOVING SEA
BREEZE AND A SUBTLE SURFACE TROUGH INLAND. SEE NO REASON TO
DEVIATE FROM THIS THINKING GIVEN THE GENERAL AGREEMENT AMONG THE
VARIOUS SYNOPTIC AND MESOSCALE MODEL SOLUTIONS. PLAN TO INCREASE
POPS TO LOW-END CATEGORICAL FOR ALL AREAS THIS AFTERNOON WITH PEAK
COVERAGE EXPECTED TO OCCUR BETWEEN 2 PM AND 6 PM.

THERE ARE SEVERAL KINEMATIC AND THERMODYNAMIC PARAMETERS THAT ARE
SUPPORTIVE OF ISOLATED STRONG TO SEVERE THUNDERSTORMS FOR SEVERAL
HOURS THIS AFTERNOON. THE PRIMARY HAZARDS WILL BE CLOUD TO GROUND
LIGHTNING WITH A RISK FOR DAMAGING WINDS AND MARGINALLY SEVERE
HAIL...HOWEVER CONDITIONS DO NOT SUPPORT A LARGE-SCALE ORGANIZED
THREAT...ALTHOUGH A BRIEF CONVECTIVE ORGANIZATION COULD OCCUR
WHERE MESOSCALE BOUNDARIES COLLIDE. HEAVY RAIN AND POSSIBLE
LOCALIZED FLOODING ARE ALSO POSSIBLE GIVEN PWATS OVER 2 STANDARD
DEVIATIONS ABOVE CLIMATOLOGY AND WIND PROFILES SUPPORTIVE OF
CONVECTIVE TRAINING ARE IN PLACE.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH THURSDAY/...
TONIGHT...ALTHOUGH THE SHORT WAVE ALOFT PULLS AWAY DURING THE
EVENING...A WEAK SOUTHERN STREAM MID AND UPPER LOW HANGS BACK OVER
THE SE AND NORTH GULF COAST STATES. THIS FEATURE ALOFT CAUSES A WEAK
SURFACE WAVE TO FORM ALONG A BAROCLINIC ZONE OVER THE NEARBY
ATLANTIC LATE AS THE PRESSURE PATTERN ACROSS SC AND GA BECOMES ILL
DEFINED. THE BULK OF THE CONVECTION WILL COME TO AN END WITH THE
PASSAGE OF THE DISTURBANCE ALOFT THIS EVENING...BUT DUE TO THE
PROXIMITY TO THE SURFACE WAVE OVER THE GULF STREAM WE/LL MAINTAIN
SLIGHT CHANCE TO CHANCE POPS THROUGH THE NIGHT. OF MORE CONCERN WILL
BE THE POTENTIAL FOR FOG FORMATION. DEPENDING UPON EXACTLY HOW MUCH
RAINFALL OCCURS TODAY...THE GROUNDS WILL BE QUITE SATURATED. THAT
ALONG WITH THE LACK OF WINDS AND CROSS-OVER TEMPS BEING REACHED
SUGGESTS THAT AREAS OF FOG WILL FORM. SOME OF THE FOG COULD BECOME
DENSE AND WE/LL NEED TO KEEP WATCH FOR A POSSIBLE DENSE FOG
ADVISORY. TEMPS WILL AGAIN BE ABOVE CLIMATOLOGICAL NORMALS...ALTHOUGH
SEVERAL DEGREES LOWER THAN WE WERE THIS MORNING.

TUESDAY...A TROUGH OF LOW PRESSURE AT THE SURFACE AND ALOFT WILL
LIKELY PERSIST OVER THE REGION INSTEAD OF OF PUSHING OFFSHORE...AND
THIS WILL TRANSLATE TO A CONTINUATION OF UNSETTLED CONDITIONS WITH
PLENTY OF CLOUDS AND SHOWERS/THUNDERSTORMS. MODELS DEPICT A SLIGHTLY
DRIER ENVIRONMENT TUESDAY AS COMPARED TO TODAY...ALTHOUGH THE
DEGREE/LOCATION OF DRYING VARIES. MAINTAINED POPS NO HIGHER THAN
CHANCE...ALTHOUGH SLIGHTLY GREATER DIURNAL COVERAGE IS POSSIBLE
TUESDAY AFTERNOON ACROSS NORTHERN COUNTIES. DESPITE CLOUDS AND
SHOWERS...TEMPERATURES SHOULD STILL RECOVER TO AROUND 80F AWAY FROM
THE COAST...CLOSE TO NORMAL FOR LATE APRIL.

TUESDAY NIGHT THROUGH THURSDAY...AS THE UPPER BLOCKING HIGH
AMPLIFIES OVER THE EASTERN GREAT LAKES...THE ASSOCIATED SURFACE HIGH
WILL STRENGTHEN AND EXPAND SOUTH/SOUTHWEST...CREATING AN IMPRESSIVE
WEDGE REGIME EAST OF THE APPALACHIANS. THE SURFACE PRESSURE GRADIENT
WILL TIGHTEN BETWEEN THE INLAND WEDGE AND A SHARP SURFACE TROUGH OFF
THE SOUTHEAST COAST. MEANWHILE...MOST GUIDANCE NOW DEPICTS THE UPPER
LOW BLOCKED OVER THE SOUTHEAST WRAPPING AN EXTENSIVE EAST/WEST BAND
OF DEEP LAYER MOISTURE INTO THE REGION...PERHAPS AS EARLY AS
WEDNESDAY BUT MORE LIKELY THURSDAY...WITH UNCERTAIN TIMING DUE TO
MODEL DIFFERENCES REGARDING THE POSITION...STRENGTH...ORIENTATION
AND EVOLUTION OF THE UPPER LOW. IN GENERAL...MAINTAINED SLIGHT
CHANCE TO CHANCE POPS TUESDAY NIGHT INTO WEDNESDAY NIGHT...THEN
BUMPED POPS UP THURSDAY. HOWEVER...GIVEN UNCERTAINTY CAPPED HIGHEST
POPS AROUND 50 PERCENT CENTRAL/SOUTH THURSDAY.

&&

.LONG TERM /THURSDAY NIGHT THROUGH SUNDAY/...
A BLOCKING PATTERN WILL PREVAIL ACROSS THE EASTERN CONUS LATE WEEK
INTO NEXT WEEKEND. AT THE SURFACE...STRONG HIGH PRESSURE CENTERED
NORTH/NORTHEAST OF THE REGION WILL CONTINUE SUPPORT A WEDGE REGIME
EAST OF THE APPALACHIANS...WHILE BROAD LOW PRESSURE...EITHER AN
INVERTED TROUGH OR A CYCLONE...WILL PERSIST SOUTH OF THE REGION.
THIS SCENARIO WILL MAINTAIN ELEVATED ONSHORE FLOW AND BELOW NORMAL
DAYTIME TEMPERATURES. ALOFT...THE CENTER OF THE BLOCKING RIDGE WILL
REMAIN NORTH OF THE REGION...AND A BROAD WEAKNESS/UPPER TROUGH WILL
PERSIST ON THE SOUTHERN PERIPHERY OF THE UPPER RIDGE...EXTENDING
BETWEEN THE DEEP TROUGH WESTERN ATLANTIC TO THE DEEP UPPER LOW OVER
THE CENTRAL CONUS. STRENGTHENING HIGH PRESSURE AT THE SURFACE AND
ALOFT SHOULD SHUNT LOW PRESSURE AND SOUTH OF THE REGION...BUT
GUIDANCE CONTINUES TO DIFFER REGARDING THE RELATIVE
POSITION/ORIENTATION...STRENGTH AND EVOLUTION OF SIGNIFICANT
FEATURES...AND RUN TO RUN MODEL CONSISTENCY HAS REMAINED POOR.
GUIDANCE HAS TRENDED TOWARD A PERSISTENT BAND OF DEEP LAYER MOISTURE
AND ELEVATED POPS ESPECIALLY OVER SOUTHERN/WESTERN COUNTIES THURSDAY
NIGHT INTO FRIDAY OR SATURDAY...FOLLOWED BY EITHER A GENERAL PUSH OF
ENHANCED MOISTURE BACK TOWARD THE NORTH/EAST AT SOME POINT OVER THE
WEEKEND AS THE DEEP CENTRAL CONUS UPPER LOW BEGINS TO ROLL EAST OR A
BREAK DOWN OF THE BLOCKING PATTERN AND BUILDING HEIGHTS ALOFT/DRYING
AS DEPICTED BY THE 29/00Z EUROPEAN MODEL. FORECAST CONFIDENCE
REMAINS INSUFFICIENT TO IMPLEMENT MAJOR CHANGES TO ONGOING SLIGHT
CHANCE/CHANCE POPS THROUGH THE PERIOD. LOW LEVEL STABILITY PROVIDED
BY THE NORTHERN HIGH WILL GREATLY LIMIT OR ELIMINATE THE POTENTIAL
FOR DIURNAL THUNDERSTORMS.

&&

.AVIATION /17Z MONDAY THROUGH FRIDAY/...
DEEP LAYER MOISTURE CONTINUES TO COVER BOTH TERMINALS...BUT CIGS
HAVE SCATTERED OUT AND CONDITIONS WILL REMAIN VFR. SHOWERS ARE
BEGINNING TO INCREASE IN AREA AND WILL BE OVER KCHS AND KSAV FOR THE
REST OF THE AFTERNOON. AS TEMPERATURES CONTINUE TO RISE...SOME
SHOWERS WILL STRENGTHEN INTO THUNDERSTORMS. STORMS WILL BE RATHER
SHORT DUE TO A 20 KNOT STORM MOTION. VSBY COULD REACH MVFR IF
THUNDERSTORMS DEVELOP OVER THE TERMINALS. THE TEMPS HAVE ALREADY
REACHED THE UPPER 70S...SO NOT EXPECTING MUCH MORE HEATING...BUT
ANY BREAKS IN CLOUD COVER WILL ALLOW FOR ADDITIONAL HEATING.
SHOWERS LOOK TO DECREASE AROUND SUNSET AND WITH TEMPERATURES
EXPECTED TO DROP TO THE LOW 60...CALM WINDS AND RESIDUAL
MOISTURE...FOG COULD BE A FACTOR. CONDITIONS LOOK MORE FAVORABLE
INLAND...BUT MVFR/IFR CONDITIONS ARE A GOOD POSSIBILITY. MODELS
ARE IN GOOD AGREEMENT OF A DECREASE IN MOISTURE ON TUESDAY AND
BOTH TERMINALS SHOULD GO BACK TO VFR BY MID MORNING.

EXTENDED AVIATION OUTLOOK...FLIGHT RESTRICTIONS EXPECTED AT LEAST
THROUGH TUESDAY MORNING. OCCASIONAL FLIGHT RESTRICTIONS WILL
REMAIN POSSIBLE THROUGH THE WEEK. FORECAST CONFIDENCE REMAINS
LOW.

&&

.MARINE...
TODAY...THE LOCAL WATERS WILL LIE WITHIN THE SW PERIPHERY OF
STRONG HIGH PRESSURE IN THE ATLANTIC...SUPPLYING THE LOCAL WATERS
WITH GENTLE TO MODERATE SOUTH TO SW BREEZES. SEAS WILL BE A
MIXTURE OF WIND DRIVEN WAVES AND LONG PERIOD SWELLS...WITH THE
SWELL LENGTH AT VALUES MORE TYPICAL OF TROPICAL SYSTEMS OR WHAT IS
SEEN IN THE PACIFIC. WHEN COMBINED TOGETHER THERE COULD BE SOME 6
FOOTERS THAT IMPINGE ON THE OUTER GA WATERS. HOWEVER...THESE 6
FOOT SEAS LOOK TO ENCOMPASS ONLY A SMALL AREA OF THE ENTIRE AMZ374
MARINE ZONE. THUS WE HAVE OPTED NOT TO HOIST THE SCA.
ELSEWHERE...SEAS WILL PEAK AT 4 OR 5 FT...WITH EVEN SOME 1-2
FOOTERS NEAR THE MOUTH OF CHARLESTON HARBOR. SCATTERED TO NUMEROUS
SHOWERS AND A FEW T-STORMS WILL BE COMMON THROUGHOUT THE DAY.
HEAVY RAINS AND LOCAL VISIBILITIES DOWN UNDER 1 NM AT TIMES WILL
OCCUR.

TONIGHT...THE ATLANTIC RIDGE SLIDES FURTHER EAST...AS A WEAK WAVE OF
LOW PRESSURE FORMS OFF THE SC/GA COASTS OUT NEAR THE GULF STREAM
AFTER MIDNIGHT. LIGHT TO GENTLE SOUTHERLY WINDS EARLY ON WILL
BECOME VARIABLE OR EVEN SHIFT TO NW LATE AS THIS TRANSPIRES. FOG
THAT FORMS OVER LAND AREAS COULD BECOME A PROBLEM FOR NAVIGATION AS
THE OFFSHORE FLOW DEVELOPS LATE.

TUESDAY THROUGH LATE WEEK...AFTER A WEAK PRESSURE GRADIENT SUPPORTS
RELATIVELY TRANQUIL CONDITIONS TUESDAY AND TUESDAY NIGHT...PRIMARY
FORECAST ATTENTION TURNS TO THE POTENTIAL FOR HAZARDOUS WINDS AND
SEAS TO DEVELOP ACROSS COASTAL WATERS WEDNESDAY INTO THIS WEEKEND.
A TIGHT PRESSURE GRADIENT WILL DEVELOP BETWEEN A STRENGTHENING
INLAND WEDGE OF HIGH PRESSURE AND A SHARP TROUGH OF LOW PRESSURE
OFF THE SOUTHEAST COAST. THIS LONG DURATION EVENT...WHICH BY LATE
WEEK COULD FEATURE AN INCREDIBLY LONG FETCH OF NORTHEAST WINDS
FROM THE NORTH ATLANTIC INTO THE SOUTHEAST COAST...WILL CERTAINLY
PRODUCE SMALL CRAFT ADVISORY WINDS AND COULD WELL PRODUCE
GALES...ACCOMPANIED BY UNUSUALLY HIGH SEAS.

RIP CURRENTS...GIVEN SEVERAL DAYS NOW OF AN ONSHORE FETCH...THERE IS
A SMALL BUT LONG PERIOD SWELL OVER THE LOCAL WATERS. THIS WILL
SUPPORT A MODERATE RISK OF RIP CURRENTS AT AREA BEACHES TODAY.

THE STRONG/LONG DURATION ONSHORE FLOW WILL LIKELY
ELEVATE THE THREAT FOR RIP CURRENTS ON AREA BEACHES MID WEEK INTO
NEXT WEEKEND.

&&

.TIDES/COASTAL FLOODING...
STRONG ONSHORE WINDS COULD PRODUCE HIGH SURF...BEACH EROSION AND
PERHAPS EVEN SHALLOW COASTAL FLOODING ESPECIALLY AROUND THE TIMES OF
HIGH TIDE DURING THE LATTER HALF OF THE WEEK INTO NEXT WEEKEND.

&&

.CHS WATCHES/WARNINGS/ADVISORIES...
GA...NONE.
SC...NONE.
MARINE...NONE.
