AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHARLESTON SC
1259 AM EDT SUN SEP 14 2014

.SYNOPSIS...
A COLD FRONT TO THE NORTH AND WEST WILL STALL NEARBY THROUGH EARLY
NEXT WEEK...BEFORE A STRONGER COLD FRONT PUSHES THROUGH THE REGION
BY THE MIDDLE OF THE WEEK. STRONG SURFACE HIGH PRESSURE WILL BUILD
FROM THE NORTH IN THE WAKE OF THE FRONT DURING THE LATE WEEK PERIOD.

&&

.NEAR TERM /UNTIL 6 AM THIS MORNING/...
THE BEST CHANCES FOR SHOWERS/TSTMS OVERNIGHT WILL GRADUALLY SHIFT
TO THE NORTHERN ZONE AS LOW-LEVEL CONVERGENCE INCREASES AHEAD OF
THE APPROACHING BACKDOOR COLD FRONT. ADJUSTED NEAR TERM POPS TO
REFLECT THIS THINK...INCREASING THEM BY ABOUT 10-20 PERCENT. RISK
FOR FLOODING WILL BE PRESENT THROUGH SUNRISE..ESPECIALLY NORTH OF
A LINE FROM WALTERBORO TO DOWNTOWN CHARLESTON.

&&

.SHORT TERM /6 AM THIS MORNING THROUGH TUESDAY/...
SUNDAY...THE SECOND DAY OF THE WEEKEND PROMISES TO BE A FAIRLY
ACTIVE CONVECTIVE DAY...COURTESY OF ABUNDANT AND DEEP MOISTURE...A
COLD FRONT SITUATED ACROSS THE FORECAST AREA...SOME UPPER LEVEL
DIVERGENCE AND ADEQUATE INSTABILITY. THE CHALLENGE THOUGH WILL BE
TWOFOLD...WHERE THE FRONT WILL ORIENT ITSELF AND THUS THE RESULTING
COVERAGE OF CONVECTION...PLUS OUR DIURNAL TEMP CURVE WHICH WILL BE
DICTATED TO THE FIRST CONDITION.

THE DAY WILL START WITH LEFTOVER SCATTERED CONVECTION NEAR OR JUST
OUTSIDE OUR NW ZONES IN PROXIMITY TO THE 850 MB FRONT...WITH A
GREATER CONCENTRATION NEAR THE IMMEDIATE COAST OR MORE LIKELY JUST
OFFSHORE. WITH CONVECTIVE TEMPS IN THE LOWER AND MIDDLE 80S HOWEVER
LAND BASED CONVECTION WILL DEVELOP QUICKLY...AND COVERAGE WILL
INCREASE DURING THE SECOND HALF OF THE MORNING INTO THE AFTERNOON.
FOR NOW WE HAVE PAINTED THE BEST RISK OF SHOWERS AND T-STORMS FROM
CHARLESTON AND BERKELEY COUNTIES TO LOCATIONS WEST AND SW OF
SAVANNAH IN PROXIMITY TO THE COLD FRONT AND WHERE IT INTERACTS WITH
THE SEA BREEZE AND VARIOUS MESO-SCALE BOUNDARIES. HIGHEST
PROBABILITIES WILL BE 60-70 PERCENT IN THESE LOCATIONS...WITH 40-50
POPS ELSEWHERE. STORM MOTION IS SLUGGISH AND WITH PWATS BETWEEN 1
AND 2 STANDARD DEVIATIONS ABOVE NORMAL WE ANTICIPATE OCCASIONAL
HEAVY RAINS AND AT LEAST MINOR FLOODING CONCERNS. IN FACT WITH THE
COLD FRONT IN THE VICINITY WE MIGHT NEED TO CONSIDER A LARGER AND
MORE ENHANCED RISK OF FLOODING. FOR NOW WE/LL ADD TO THE HAZARDOUS
WEATHER OUTLOOK...BUT ANY FLASH FLOOD WATCH POTENTIAL IS NOT YET
HIGH ENOUGH TO WARRANT ISSUING SUCH A PRODUCT.

CONSIDERABLE CLOUD COVER WILL HOLD TEMPS DOWN IN THE MID OR UPPER
80S...AND THE ONSET OF THE RAIN-COOLED ENVIRONMENT WILL RESULT THE
DIURNAL TEMP CURVE BOUNCING AROUND PENDING WHEN AND WHERE IT/S
RAINING. WE HAVE TRENDED THE CURVE TOWARD SUCH CONDITIONS BUT NO
DOUBT FUTURISTIC ADJUSTMENTS WILL BECOME NECESSARY.

SUNDAY NIGHT...INTERACTING/MERGING BOUNDARIES AND PLENTIFUL MOISTURE
WILL ALLOW FOR ONLY SLOWLY DIMINISHING CONCENTRATION TO SHOWERS AND
T-STORMS IN THE EVENING. AND GIVEN THE COLD FRONT LYING NEAR OR
CENTRAL ZONES WE ARE COMPELLED TO HOLD ONTO SLIGHT CHANCE AND CHANCE
POPS EVEN AFTER MIDNIGHT. THERE ARE INDICATIONS OF SOME BUILD-DOWN
OF STRATUS LATE...AND WITH CONDENSATION PRESSURE DEFICITS AS LOW AS
10-30 MB AND SOME LOCALES TO ACHIEVE THEIR CROSS-OVER TEMPS WE ARE
CARRYING PATCHY LATE NIGHT FOG FAR INLAND. LOWS WILL AVERAGE IN THE
LOWER OR MIDDLE 70S...EXCEPT FOR A FEW UPPER 60S NW TIER.

MONDAY...THE SURFACE COLD FRONT BECOMES MORE ILL-DEFINED AS IT
BECOMES MASKED BY SEA BREEZE CIRCULATIONS. IN TURN THE SURFACE
PRESSURE PATTERN IS ALSO LESS PRONOUNCED AND QUITE NEBULOUS.
MESO-SCALE BOUNDARIES AND THE REMNANTS OF THE COLD FRONT WILL HAVE
AMPLE MOISTURE AN INSTABILITY TO AGAIN TRIGGER AN ENHANCED RISK FOR
SHOWERS AND T-STORMS. COVERAGE WILL INCREASE DURING THE LATE MORNING
AND AFTERNOON AS WE ACHIEVE OUR CONVECTIVE TEMPS AND BOUNDARY
INTERACTIONS OCCUR. HIGHEST CHANCES WILL BE INLAND FROM THE US-17
CORRIDOR...PEAKING IN THE 50-60 PERCENTILE. WIND FIELDS IN THE
STEERING LAYER FROM ROUGHLY 800-600 MB IS YET AGAIN
WEAK...SUPPORTIVE OF LOCALLY HEAVY RAINFALL. AND SIMILAR TO MONDAY
OUR TEMPS WILL BE DICTATED BY ONSET OF CONVECTION...BUT STILL WE
SHOULD REACH THE MID AND UPPER 80S ACROSS THE BOARD.

TUESDAY...A BROAD TROUGH WILL HAVE SET UP ACROSS THE EASTERN UNITED
STATES AND WILL SEND THE NEXT UPSTREAM COLD FRONT TOWARD THE
FORECAST AREA FROM THE NW LATE IN THE PERIOD. EMBEDDED WITHIN THE
TROUGH WE FIND A FAIRLY WELL DEFINED SHORT WAVE THAT WAS LOCATED IN
NORTHERN OLD MEXICO ON SATURDAY...THAT SHIFTS THROUGH DURING THE
DAY. THE ADDITIONAL FORCING ALOFT WITH THIS FEATURE PLUS THE RIGHT
ENTRANCE REGION TO THE NEARBY UPPER JET WILL TRIGGER AT LEAST
SCATTERED POPS. THERMODYNAMICS ARE GOOD AND THERE IS SOME STRONGER
MID LEVEL FLOW WITH 0-6 KM BULK SHEAR ON THE ORDER OF 25-30
KT...WHICH POINTS TOWARD THE POTENTIAL OF A FEW STRONGER OR EVEN
ISOLATED SEVERE STORMS. A DEEP OFFSHORE FLOW WILL HELP IN NEGATING
THE EXTENSIVE CLOUD COVER AND TEMPS WILL MAX OUT NEAR MID-SEPTEMBER
NORMS.

&&

.LONG TERM /TUESDAY NIGHT THROUGH SATURDAY/...
THE AXIS OF THE UPPER TROUGH WILL BE AMPLIFYING JUST UPSTREAM BY
THE MID WEEK PERIOD...WHILE THE COLD FRONT MOVING OFF THE
COASTLINE STALLS JUST TO THE SOUTH AND EAST. SHORTWAVE ENERGY
MOVING ALONG THE BASE OF THE UPPER TROUGH COULD SUPPORT THE
FORMATION OF LOW PRESSURE WAVES ALONG THE LINGERING OFFSHORE FRONT
WEDNESDAY THROUGH LATE WEEK. SURFACE HIGH PRESSURE WILL BE
BUILDING STRONGLY FROM THE NORTH AT THE SAME TIME...WITH THE
OFFSHORE LOW PRESSURE/COASTAL TROUGH FORMING THE PERIPHERY OF A
WELL-DEFINED INLAND WEDGE STRETCHING DOWN THE APPALACHIAN REGION.
IF THIS PATTERN EVOLVES AS MEDIUM RANGE MODEL SOLUTIONS ARE
SUGGESTING...THEN STRONG NORTH/NORTHEAST FLOW COULD DEVELOP
THURSDAY INTO POSSIBLY THE WEEKEND AND SUPPORT NOTABLY COOLER
CONDITIONS. HAVE INDICATED HIGH TEMPERATURES BEHIND THE FRONT ON
WEDNESDAY IN THE MID 80S...TRENDING EVEN COOLER IN THE LOW 80S FOR
THE LATE WEEK TIME FRAME. LOW TEMPERATURES WILL ALSO REFLECT THE
WEDGE PATTERN...FALLING INTO THE LOW TO MID 60S BY THURSDAY NIGHT.

RAIN CHANCES WILL STILL BE RATHER HIGH IN THE 30 TO 40 PERCENT
RANGE ON WEDNESDAY AND THURSDAY...WITH BEST COVERAGE ACROSS
SOUTHERN AREAS CLOSEST TO THE LINGERING FRONT. SHOWER/THUNDERSTORM
POTENTIAL IS THEN EXPECTED TO DECREASE FRIDAY AND SATURDAY...AS
THE BEST MOISTURE AND CONVERGENCE REMAINS OFFSHORE WITH THE
INTENSIFYING COASTAL TROUGH.

&&

.AVIATION /06Z SUNDAY THROUGH THURSDAY/...
POTENTIALLY VERY ACTIVE DAY AT THE TERMINALS AS A BACKDOOR COLD
FRONT STALLS OVER THE AREA. EARLY MORNING SHOWER/TSTM ACTIVITY IS
EXPECTED TO REMAIN WEST AND NORTH OF KCHS...ALTHOUGH IT MAY BRUSH
THE TERMINAL THROUGH SUNRISE. WILL MONITOR TRENDS THERE BUT NOT
INCLUDE TSRA JUST YET. BEST CHANCES FOR TSTM IMPACTS WILL BE FROM
17-20Z AT KCHS AND 19-22Z AT KSAV...ALTHOUGH THESE WINDOWS MAY
NEED TO BE REDEFINED AS THE DAY PROGRESSES. IFR CONDITIONS ARE
CERTAINLY POSSIBLE GIVEN THE HIGH MOISTURE VALUES THAT ARE IN
PLACE...BUT WILL CAP CONDITIONS AT MVFR FOR NOW.

EXTENDED AVIATION OUTLOOK...PERIODIC RAIN CHANCES AND POSSIBLE
TEMPORARY FLIGHT RESTRICTIONS THROUGH EARLY NEXT WEEK...AS A COLD
FRONT STALLS OVER OR NEAR THE AREA. SOME EARLY MORNING FOG AND/OR
LOW CLOUDS WILL ALSO BE POSSIBLE...ALSO RESULTING IN THE RISK OF
SUB-VFR WEATHER.

&&

.MARINE...
OVERNIGHT...A WEAK COLD FRONT WILL SHIFT SOUTHEAST TOWARD THE
NORTHERN SOUTH CAROLINA WATERS. A WEAK PRESSURE GRADIENT IS IN
PLACE. WINDS MAINLY 10 KT OR LESS AND SEAS 1-2 FT OVERNIGHT. WINDS
WILL BE VARIABLE IN DIRECTIONS AT TIMES.

SUNDAY THROUGH TUESDAY...OUTSIDE OF CONVECTION AND ANY POTENTIAL
WATERSPOUT ACTIVITY...WIND AND SEA CONDITIONS WILL BE RATHER QUIET.
WINDS WILL TURN ONSHORE SUNDAY INTO SUNDAY NIGHT...BEFORE
TEMPORARILY VEERING TO AN OFFSHORE FETCH LATE SUNDAY NIGHT/EARLY
MONDAY WITH LAND BREEZE INFLUENCES. THE PATTERN WILL THEN START ANEW
AGAIN LATER MONDAY MORNING AND PERSIST INTO TUESDAY. MARINERS SHOULD
MONITOR NOAA WEATHER RADIO ALL HAZARDS OR ASSOCIATED VHF CHANNELS
SINCE THERE IS A RISK FOR OCCASIONAL STRONGER STORMS THROUGH THE
PERIOD.

WEDNESDAY THROUGH FRIDAY...A MID WEEK AND STRONGER COLD FRONT WILL
PUSH THROUGH THE LOCAL WATERS AS A BUILDING HIGH PRESSURE WEDGE
DEVELOPS INLAND. A ROBUST PINCHING OF THE NE GRADIENT WILL GRADUALLY
DEVELOP FOR THURSDAY AND FRIDAY...AND WINDS AND SEAS WILL BE
SIGNIFICANTLY HIGHER. SMALL CRAFT ADVISORIES SEEM A GOOD BET THE
SECOND PART OF THE WEEK.

WATERSPOUTS...CONDITIONS APPEAR TO FAVOR THE DEVELOPMENT OF
WATERSPOUTS SUNDAY MORNING GIVEN LIGHT WIND FIELDS...SUFFICIENT
MOISTURE AND INSTABILITY AND AN EAST/NE TO SW/WEST ALIGNED COLD FRONT
BISECTING COASTAL WATERS. HOWEVER...SINCE ANY WATERSPOUTS WILL BE SO
ISOLATED IN SCOPE WE WILL DEFER TO THE MIDNIGHT FORECASTERS AS TO
WHETHER TO ADD TO THE HAZARDOUS WEATHER OUTLOOK AND/OR TO ISSUE A
MARINE WEATHER STATEMENT.
