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

.SYNOPSIS...
A DISTURBANCE ALOFT WILL MOVE THROUGH THE REGION THIS EVENING...
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 AM TUESDAY MORNING/...
NUMEROUS SHOWERS AND TSTMS ARE AFFECTING MUCH OF SOUTHEAST SOUTH
CAROLINA AND SOUTHEAST GEORGIA LATE THIS AFTERNOON. ACTIVITY IS
EXPECTED TO PEAK OVER THE NEXT 1-2 HRS AS INSTABILITY...LOW-
LEVEL CONVERGENCE BETWEEN THE INLAND MOVING SEA BREEZE AND THE
INLAND SURFACE AND UPPER FORCING WITH THE SHORTWAVE APPROACHING
THE CSRA MAXIMIZE. INSTABILITY PROFILES STILL SUPPORT A RISK FOR
ISOLATED SEVERE TSTMS WITH MARGINALLY SEVERE HAIL...DAMAGING
WINDS...FREQUENT CLOUD-TO-GROUND LIGHTNING AND LOCALIZED FLOODING
BEING THE PRIMARY CONCERNS. WILL CONTINUE TO HIGHLIGHT CATEGORICAL
POPS FOR MANY AREAS THROUGH 6 PM. ACTIVITY IS EXPECTED TO STEADILY
WANE THIS EVENING AS INSTABILITY DIMINISHES IN RESPONSE TO
ATMOSPHERIC OVERTURNING AND DIFFERENTIAL NEGATIVE VORTICITY
ADVECTION BEGINS TO SPREAD IN FROM THE WEST IN THE WAKE OF THE
SHORTWAVE.

MODELS SHOW WEAK LOW PRESSURE DEVELOPING OFF THE COAST TONIGHT IN
RESPONSE TO A SECONDARY IMPULSE PIVOTING ACROSS THE SOUTHERN
GEORGIA AND INTERACTING WITH STRONG BAROCLINICITY ALONG THE WESTERN
WALL OF THE GULF STREAM. THERE MAY BE JUST ENOUGH LIFT AND LOW-
LEVEL CONVERGENCE TO SUPPORT ISOLATED TO PERHAPS SCATTERED
SHOWERS AND POSSIBLE A TSTM OR TWO ACROSS MAINLY THE COASTAL
COUNTIES AFTER MIDNIGHT. WILL SHOW 20-30 PERCENT CHANCE OVERNIGHT
WITH NON-MENTIONABLE POPS ACROSS FAR INTERIOR SOUTHEAST GEORGIA.
LOWS WILL RANGE FROM THE UPPER 50S INLAND TO THE LOWER 60S AT THE
COAST.

THERE ARE SOME INDICATIONS THAT LOW CLOUDS WILL FILL IN LATE
TONIGHT. AREAS OF FOG ARE POSSIBLE DUE TO STRATUS BUILD DOWN...BUT
ITS UNCLEAR HOW WIDESPREAD ANY FOG WILL BECOME. GUIDANCE KEEPS
VSBYS OUT OF DENSE FOG ADVISORY THRESHOLDS...BUT SUSPECT AT LEAST
POCKETS OF DENSE FOG COULD OCCUR. WILL MAINTAIN AREAS OF FOG IN
THE GRIDDED AND TEXT FORECASTS AND HIGHLIGHT A POTENTIAL FOR DENSE
FOG IN THE HAZARDOUS WEATHER OUTLOOK.

&&

.SHORT TERM /6 AM TUESDAY MORNING THROUGH THURSDAY/...
TUESDAY...A MID LVL RIDGE WILL CONTINUE AN EASTWARD SHIFT OVER THE
WESTERN ATLANTIC LEADING WAY TO A H5 SHORTWAVE SLOWLY PASSING OVER
THE FORECAST AREA DURING THE AFTERNOON. MODELS ARE IN GENERAL
AGREEMENT THAT A WEAK SFC LOW WILL DEVELOP IN RESPONSE TO THIS
FEATURE ALONG THE SOUTHEAST COAST NEAR THE WESTERN EDGE OF ATLANTIC
HIGH PRESSURE. THIS SHOULD LEAD TO AN INCREASING CHANCE OF SHOWERS
AND/OR THUNDERSTORMS DURING AFTERNOON HOURS WITH ACTIVITY DRIFTING
ONSHORE...ESPECIALLY ALONG THE NORTHERN PERIPHERY OF THE SFC LOW.
HAVE THEREFORE MAINTAINED GREATEST CHANCE POPS OVER COASTAL COUNTIES
IN SOUTHEAST SOUTH CAROLINA FROM EARLY MORNING INTO PEAK HEATING
HOURS. 1000-850 MB THICKNESSES FAVOR OVERALL HIGH TEMPS IN THE UPPER
70S TO LOWER 80S...HIGHEST OVER SOUTHEAST GEORGIA. GIVEN THE AMOUNT
OF HEATING...HAVE ALSO MAINTAINED A SLIGHT CHANCE OF SHOWERS AND/OR
THUNDERSTORMS OVER ALL AREAS IN SOUTHEAST GEORGIA. OVERNIGHT LOWS
ARE EXPECTED TO BE IN THE UPPER 50S TO LOWER 60S.

WEDNESDAY...A FAIRLY LOW CONFIDENCE FORECAST IS IN PLACE GIVEN THE
TRACK OF A WEAK SFC LOW OFF THE SOUTHEAST COAST...BUT THE GENERAL
CONSENSUS IS THAT THERE SHOULD BE A LULL IN PRECIP ACTIVITY THROUGH
A LARGE PART OF THE DAY AS A WEDGE OF SFC HIGH PRESSURE BUILDS FROM
THE NORTH OVER LAND. HAVE THEREFORE LIMITED CHANCES OF SHOWERS
AND/OR ISOLATED THUNDERSTORMS TO COASTAL COUNTIES AND EXTREME
SOUTHEAST GEORGIA COUNTIES WHERE BOUNDARY LAYER MOISTURE AND HEATING
ARE GREATEST. 1000-850 MB THICKNESSES FAVOR OVERALL HIGH TEMPS IN
THE MID TO UPPER 70S...HIGHEST OVER SOUTHEAST GEORGIA. OVERNIGHT
LOWS SHOULD BE IN THE MID 50S TO LOWER 60S.

THURSDAY...A WEAK SFC LOW LOOKS TO DEVELOP OVER THE NORTHERN GULF OF
MEXICO AHEAD OF A HIGH AMPLITUDE MID LVL TROUGH DIGGING OVER THE
CENTRAL UNITED STATES. AS THIS OCCURS...BOUNDARY LAYER MOISTURE AND
ISENTROPIC ASCENT SHOULD INCREASE OVER SOUTHEAST GEORGIA
EARLY...THEN SOUTHEAST SOUTH CAROLINA LATE. CHANCES OF SHOWERS
SHOULD ALSO INCREASE OVER THE FORECAST AREA DURING THE EVENING AS
PWATS APPROACH 1.5 INCHES OVER SOUTHEAST GEORGIA IN RESPONSE TO THE
WEAK SFC LOW DRIFTING EAST TO THE FLORIDA PENINSULA. CAN NOT RULE
OUT A SLIGHT CHANCE OF THUNDER OVER SOUTHEAST GEORGIA WHERE MOISTURE
AND OVERALL TEMPS WILL BE WARMEST. HOWEVER...OVERCAST SKIES WILL
LIKELY LIMIT OVERALL COVERAGE. AFTERNOON HIGH TEMPS SHOULD BE COOLER
DUE TO EXPANSIVE CLOUDS...IN THE LOW/MID 70S.

&&

.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 /19Z MONDAY THROUGH SATURDAY/...
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...MVFR OR LOWER CIGS/VSBYS POSSIBLE TUESDAY
AND WEDNESDAY MORNING DUE TO FOG AND/OR SHOWERS. PERIODS OF MVFR
CONDITIONS THEN POSSIBLE THROUGH THURSDAY BUT FORECAST CONFIDENCE
REMAINS LOW. ODDS FAVOR MAINLY VFR CONDITIONS THROUGH THE REMAINDER
OF THE FORECAST PERIOD...ALTHOUGH OCCASIONAL FLIGHT RESTRICTIONS
WILL REMAIN POSSIBLE. FORECAST CONFIDENCE REMAINS LOW.

&&

.MARINE...
TONIGHT....SOUTHERLY FLOW REGIME WILL DOMINATE FOR MUCH OF THE
NIGHT BEFORE TURNING NORTH TO NORTHWEST LATE AS LOW PRESSURE
DEVELOPS OFF THE COAST. BOTH WINDS AND SEAS WILL REMAIN BELOW
SMALL CRAFT ADVISORY THRESHOLDS.

TUESDAY THROUGH LATE WEEK...TRANQUIL CONDITIONS WILL PERSIST OVER
THE COASTAL WATERS THROUGH TUESDAY NIGHT WITH A WEAK AREA OF LOW
PRESSURE ALONG THE SOUTHEAST COAST. CONDITIONS WILL THEN BEGIN TO
DETERIORATE WEDNESDAY AS THE PRESSURE GRADIENT TIGHTENS BETWEEN A
WEDGE OF HIGH PRESSURE BUILDING FROM THE NORTH AND LOW PRESSURE
DEVELOPING OVER THE NORTHERN GULF OF MEXICO AND FLORIDA PENINSULA.
SMALL CRAFT ADVISORIES WILL LIKELY BE NEEDED FOR MOST COASTAL WATERS
WEDNESDAY NIGHT INTO THURSDAY AS NORTHEAST WINDS APPROACH 20-25 KTS
AND SEAS BUILD FROM 4-6 FT...HIGHEST OVER OUTER GEORGIA WATERS.
THERE IS ALSO A LOW CHANCE OF GALE FORCE WINDS OVER NORTHERN SC
WATERS AND OUTER GEORGIA WATERS THURSDAY INTO EARLY FRIDAY AS THE
TIGHTENING OF THE GRADIENT PEAKS. SEAS COULD BUILD AS HIGH AS
7-9 FT...HIGHEST OVER OUTER GEORGIA WATERS. 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...COULD PRODUCE SMALL CRAFT ADVISORY WINDS AND UNUSUALLY HIGH
SEAS THROUGH LATE WEEK. 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.
