Special Weather Statement, NWS Charleston, SC

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHARLESTON SC
938 AM EDT WED MAR 30 2011

.SYNOPSIS...
A SERIES OF LOW PRESSURE SYSTEMS WILL AFFECT THE REGION WEDNESDAY
THROUGH THURSDAY. A COLD FRONT WILL MOVE THROUGH THE REGION FRIDAY
NIGHT...WITH HIGH PRESSURE BUILDING BACK INTO THE REGION OVER THE
WEEKEND AND INTO EARLY NEXT WEEK.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
WEDNESDAY MORNING SURFACE ANALYSIS DEPICTED A COMPLEX SCENARIO
ACROSS THE SOUTHEAST...FEATURING A WARM FRONT GRADUALLY PUSHING
N/NW INTO S/E COASTAL WATERS AND FAR S COUNTIES AND A GRADUALLY
WEAKENING WEDGE OVER N/INLAND COUNTIES.

THE PRIMARY FORECAST CONCERNS FOR TODAY INCLUDE THE POTENTIAL FOR
ELEVATED SEVERE THUNDERSTORMS THROUGH EARLY AFTERNOON...THE
POTENTIAL FOR SURFACE BASED SEVERE THUNDERSTORMS NEAR THE SURFACE
WARM FRONT ACROSS SOUTHERN COUNTIES THIS AFTERNOON/EVENING AND THE
POTENTIAL FOR LOCALLY HEAVY RAINFALL. TEMPERATURE FORECASTS WILL
ALSO REMAIN VERY DIFFICULT TODAY.

WEDNESDAY MORNING...DEEP LAYER FORCING/ASCENT AND 700-500 MB LAPSE
RATES EXCEEDING 7.5 C/KM SUPPORTED AN EXPANDING AREA OF
SHOWERS/THUNDERSTORMS ALONG/S OF THE SAVANNAH RIVER WHICH WERE
SPREADING N/E. WHERE ISOLATED/ELEVATED CELLS DEVELOP SUFFICIENTLY
DEEP UPDRAFTS...500 MB TEMPERATURES NEAR -17C WILL SUPPORT THE
THREAT FOR ISOLATED HAIL UP TO ONE INCH IN DIAMETER THROUGH EARLY
AFTERNOON. THEN...MID LEVEL LAPSE RATES WILL DIMINISH TO LESS THAN
6 C/KM AS UPSTREAM/WIDESPREAD PRECIPITATION PUSHES INTO THE
REGION...ENDING THE INITIAL POTENTIAL FOR ISOLATED/ELEVATED SEVERE
THUNDERSTORMS.

LOW PRESSURE OVER LOUISIANA WILL MOVE RAPIDLY EAST ALONG THE WARM
FRONT AND WILL APPROACH THE SOUTHERN ZONES LATE THIS AFTERNOON AS
ITS SUPPORTING SHORTWAVE SHEARS OUT ACROSS THE OHIO VALLEY. IT
REMAINS TO BE SEEN IF THE WEDGE WILL BREAK DOWN ENOUGH TODAY TO
ALLOW THE WARM SECTOR AND ASSOCIATED SURFACE-BASED INSTABILITY TO
PENETRATE NORTH/INLAND INTO THE LOCAL FORECAST AREA...OR WHETHER
WIDESPREAD PRECIPITATION WILL PROMOTE IN-SITU INTENSIFICATION OF
THE WEDGE. THE 30/06Z NAM-12 WOULD SUGGEST ONLY A VERY SMALL AREA
ALONG THE IMMEDIATE COAST AND ACROSS THE FAR SOUTH WILL REMAIN IN
TH WARM SECTOR WITH THE WEDGE HOLDING FIRM FARTHER INLAND. THE
LOWER RESOLUTION GFS IS MUCH QUICKER AND AGGRESSIVE WITH THE
EROSION OF THE WEDGE WHICH DOES NOT SEEM REASONABLE WITH DIABATIC
PROCESSES BECOMING STRONGLY REINFORCED AS WIDESPREAD RAINS FALL
INTO THE CORE OF THE WEDGE. WILL CONTINUE TO GENERALLY FAVOR THE
COOLER NAM-12. MEANWHILE...PINNING DOWN HIGH TEMPERATURES WILL BE
EXTREMELY TRICKY WITH THE WEDGE EXPECTED TO HOLD IN PLACE AND WILL
BE HEAVILY DEPENDENT ON PRECIPITATION RATES AND WARM FRONTAL
PLACEMENT. HIGH WILL RANGE FROM THE LOWER 60S INLAND TO AROUND 70
AT THE COAST AND FAR SOUTH...BUT CONFIDENCE IS LOW ESPECIALLY
ACROSS THE FAR INLAND AREAS WHERE HIGHS COULD EASILY STALL IN THE
MID-UPPER 50S SHOULD MODERATE RAINS INITIATE EARLIER THAN
EXPECTED.

INGREDIENTS REMAIN FAVORABLE FOR BENEFICIAL/WIDESPREAD RAIN TO
FALL ACROSS DROUGHT AND FIRE STRICKEN AREAS. DEEP LAYER
FORCING/ASCENT AND SUBTROPICAL MOISTURE FEATURING PWATS EXCEEDING
1.5 INCHES PER UPSTREAM 12Z SOUNDINGS...SLIGHTLY HIGHER THAN 2
STANDARD DEVIATIONS ABOVE CLIMATOLOGY...WILL CONTINUE TO ADVECT
NORTH AND BE SOLIDLY IN PLACE ACROSS THE FORECAST AREA LATER TODAY
AS SYNOPTIC DYNAMICS PEAK. IMPRESSIVE Q-G FORCING ASSOCIATED WITH
A COUPLED JET STRUCTURE SETTING UP BETWEEN DUAL JET STREAKS OVER
NORTH CAROLINA AND ALABAMA AND HIGH PWATS WILL SUPPORT WIDESPREAD
RAINS WITH POPS OF 100 PERCENT THROUGH LATE AFTERNOON. GENERAL
RAIN AMOUNTS OF 0.5-1.0 INCH APPEAR LIKELY WITH AMOUNTS
POTENTIALLY REACHING 1.5-2.0 INCHES ACROSS THE SOUTH AND ALONG
THE COAST WHERE A BAND OF MODERATE-HEAVY RAIN WILL LIKELY TRAIN
FOR SEVERAL HOURS. OF NOTE...SOME GUIDANCE SUGGESTS A SEVERE
MESOSCALE CONVECTIVE SYSTEM /MCS/ WILL DEVELOP SOUTH OF THE
REGION. THIS COULD CURTAIL STRONG THETA ADVECTION AND COULD LIMIT
RAIN AMOUNTS.

NEAR THE WARM FRONT ACROSS THE SOUTH...THE POTENTIAL EXISTS FOR
ISOLATED SEVERE THUNDERSTORMS WHICH COULD PRODUCE DAMAGING
WINDS...LARGE HAIL AND EVEN AN ISOLATED TORNADO THIS
AFTERNOON/EVENING. HOWEVER...SURFACE BASED INSTABILITY WILL REMAIN
LIMITED DUE TO WIDESPREAD CLOUDS/PRECIPITATION...WHILE MID LEVEL
LAPSE RATES ARE EXPECTED TO DECREASE WITH TIME. FURTHER...A SEVERE
MCS WILL PASS S OF THE REGION TODAY...AND THE SEVERE THREAT COULD
DEPEND ON WHETHER THE MCS CLIPS SOUTHERN COUNTIES OR REMAINS
ENTIRELY ROOTED WITHIN STRONGER INSTABILITY TO THE SOUTH. THE
HAZARDOUS WEATHER OUTLOOK ADEQUATELY ADDRESSES THE ISOLATED SEVERE
THREAT FOR THIS AFTERNOON/EVENING.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH SATURDAY/...
WIDESPREAD RAINS WILL QUICKLY DIMINISH THIS EVENING AS THE
STRONGEST FORCING SHIFTS OFFSHORE AS DOES LOW PRESSURE. WINDS WILL
TURN NORTH IN THE WAKE OF THE LOW...BUT EXTENSIVE LOW/MID-LEVEL
CLOUDINESS ALONG WITH WEAK SPOKES OF VORTICITY PASSING THROUGH
THE LAST FLOW ALOFT WILL KEEP A RISK FOR DRIZZLE AND/OR ISOLATED-
SCATTERED SHOWERS GOING THROUGH MUCH OF THE NIGHT. COMPLICATING
MATTERS IS THE POTENTIAL FOR STRATUS BUILD-DOWN FROM LATE EVENING
ON WHICH COULD RESULT IN FOG SOME OF IT DENSE. WILL FORECAST 30-40
PERCENT POPS THIS EVENING THEN DROPPING TO 20-30 PERCENT AFTER
MIDNIGHT. AREAS OF FOG WILL ALSO BE INCLUDED IN THE GRIDS AND TEXT
PRODUCTS. LATER SHIFTS WILL BE ABLE TO BETTER PIN DOWN THE FOG
POTENTIAL AS ADDITIONAL DATA SETS ARE RECEIVED. LOWS WILL RANGE
FROM AROUND 50 WELL INLAND TO THE LOWER 60S ACROSS MCINTOSH
COUNTY.

MODEL SOLUTIONS ARE IN GOOD AGREEMENT WITH THE OVERALL SYNOPTIC
PATTERN EVOLUTION THROUGH THE SHORT TERM PERIODS...ALTHOUGH MINOR
TRACK AND TIMING DIFFERENCES CONTINUE TO EXIST.

THURSDAY AND THURSDAY NIGHT...OPERATIONAL MODELS ARE IN GOOD
AGREEMENT LIFTING A WAVE OF LOW PRESSURE NORTHEASTWARD THROUGH THE
SOUTHEAST STATES OR JUST OFF THE COAST ON THURSDAY. OBVIOUSLY THE
TRACK WILL HAVE LARGE IMPLICATIONS ON FORECAST TEMPERATURES...WITH
ONLY MINOR IMPACTS TO THE SENSIBLE WEATHER FORECAST. THE AREA WILL
BE OVERSPREAD WITH DEEP MOISTURE AND STRONG FORCING FROM THE
ENTRANCE REGION OF 160+ KNOT H25 JET...SO WILL CARRY LIKELY POPS
ALL LOCALES ON THURSDAY...WITH HIGHEST PROBABILITIES IN THE
MORNING ACROSS SOUTHEAST GEORGIA AND IN THE AFTERNOON ACROSS
SOUTHERN SOUTH CAROLINA. GUIDANCE CONTINUES TO SHOW IMPRESSIVE
ELEVATED INSTABILITY...SO WILL KEEP THUNDER IN THE FORECAST AS
WELL.

THE AREA OF LOW PRESSURE WILL TRACK OFF TO THE NORTHEAST AND AWAY
FROM THE REGION THURSDAY NIGHT...SO WILL ALLOW THINGS TO DRY OUT
THURSDAY EVENING ACROSS SOUTHEAST GEORGIA WHILE KEEPING SLIGHT
CHANCE/LOW CHANCE POPS IN PLACE ACROSS SOUTHERN SOUTH CAROLINA FOR
SOME LINGERING SHOWERS. AFTER MIDNIGHT...THE GFS AND NAM SHOW AN
INCREASE IN DEEP MOISTURE ACROSS THE NORTHWESTERN TWO THIRDS OF THE
FORECAST AREA...ALONG WITH SOME FORCING FOR ASCENT IN THE LEFT FRONT
QUAD OF A 100+ KNOT NORTHWEST TO SOUTHEAST ORIENTED H25 JET. GIVEN
THE WESTERLY BOUNDARY LAYER FLOW...WE ARE NOT ANTICIPATING MUCH IN
THE WAY OF RAINFALL COVERAGE...BUT THERE REMAINS ENOUGH OF A CHANCE
FOR SOME ISOLATED LIGHT RAIN SHOWERS TO WARRANT SLIGHT CHANCE POPS
ACROSS THE NORTHWESTERN TWO THIRDS OF THE FORECAST AREA.

TEMPERATURES WILL BE QUITE DIFFICULT TO PIN DOWN THURSDAY AND WILL
BE HIGHLY DEPENDENT ON THE TRACK OF THE AREA OF LOW PRESSURE THROUGH
THE REGION. WILL TREND FORECAST TEMPERATURES TOWARD THE HIGHER
RESOLUTION NAM SOLUTION...WHICH RESULTS IN HIGHS IN THE MID/UPPER
50S ACROSS NORTHERN ZONES...AND IN LOW/MID 60S ACROSS THE SOUTH.
OVERNIGHT LOWS WILL BOTTOM OUT IN THE MID TO UPPER 40S AREA WIDE.

FRIDAY AND FRIDAY NIGHT...HIGH PRESSURE WILL BUILD SOUTH OF THE
FORECAST AREA ON FRIDAY...WITH A WEAK FRONTAL BOUNDARY OR AXIS OF
DEEPER MOISTURE REMAINING IN PLACE ACROSS NORTHERN ZONES OR JUST
NORTH OF THE FORECAST AREA. THIS BOUNDARY WILL THEN SHIFT
SOUTHWARD THROUGH THE REGION FRIDAY NIGHT. WILL CARRY SLIGHT
CHANCE POPS ACROSS NORTHERN ZONES FRIDAY IN CLOSEST PROXIMITY TO
THE WEAK FRONTAL BOUNDARY/AXIS OF DEEPER MOISTURE. WILL THEN CARRY
SLIGHT CHANCE POPS ALL AREAS FRIDAY NIGHT AS THE FRONTAL BOUNDARY
SLIPS SOUTHWARD THROUGH THE REGION. HIGHS ON FRIDAY SHOULD REBOUND
BACK CLOSER TO NORMAL UNDER A MIX OF SUN AND CLOUDS AND WESTERLY
DOWNSLOPE BOUNDARY LAYER FLOW. WE EXPECT HIGHS TO RANGE FROM
AROUND 70/LOWER 70S NORTH TO THE MID 70S ACROSS THE SOUTH. LOWS
FRIDAY NIGHT SHOULD BOTTOM OUT IN THE UPPER 40S TO AROUND 50
ACROSS NORTHERN AREAS...AND IN THE LOW/MID 50S ACROSS SOUTHERN
LOCALES.

SATURDAY...THE WEAK FRONTAL BOUNDARY/AXIS OF DEEPER MOISTURE WILL
CONTINUE TO SHIFT SOUTH OF THE FORECAST AREA. EXPECT ANY MORNING
CLOUDS TO GIVE WAY TO PLENTY OF SUNSHINE BY MID/LATE MORNING.
WESTERLY DOWNSLOPE FLOW WILL ALLOW FOR TEMPERATURES TO REBOUND
NICELY BACK INTO THE MIDDLE 70S MOST AREAS.

&&

.LONG TERM /SATURDAY NIGHT THROUGH TUESDAY/...
MODEL SOLUTIONS ARE IN GOOD AGREEMENT THROUGH THE EARLY NEXT
WEEK...WITH SOME TIMING DIFFERENCES NOTED WITH THE APPROACH OF A
COLD FRONT DURING THE EARLY TO MIDDLE PORTION OF NEXT WEEK.
OVERALL...EXPECT HIGH PRESSURE TO BUILD OVER THE AREA SATURDAY NIGHT
THROUGH MONDAY NIGHT RESULTING IN RAIN FREE WEATHER. FOR NOW WILL
CARRY SLIGHT CHANCE POPS TUESDAY THROUGH WEDNESDAY GIVEN THE
UNCERTAINTY WITH THE TIMING OF THE NEXT COLD FRONT...AND REFINE AS
DETAILS BECOME MORE CLEAR. TEMPERATURES ARE EXPECTED TO BE WITHIN A
FEW DEGREES OF NORMAL MOST PERIODS...WITH THE EXCEPTION OF MONDAY
THROUGH TUESDAY WHEN ABOVE TO MUCH ABOVE NORMAL TEMPERATURES ARE
ANTICIPATED.

&&

.AVIATION /13Z WEDNESDAY THROUGH SUNDAY/...
SHOWERS/THUNDERSTORMS WILL PRODUCE CONDITIONS VARYING FROM LIFR TO
BRIEF VFR THROUGH EARLY AFTERNOON. REMAIN ALERT FOR AMENDMENTS AS
NEAR TERM CONVECTIVE TRENDS BECOME CLEAR. PREVAILING IFR OR LOWER
CONDITIONS SHOULD TAKE HOLD THIS AFTERNOON AND STEADIER RAIN
OVERSPREADS THE REGION.

THE STEADIER RAINS WILL MOVE EAST OF THE TERMINALS BY SUNSET BUT
CONSIDERABLE LOW-LEVEL MOISTURE COUPLED WITH A RE-INTENSIFICATION
OF ISENTROPIC ASSENT WILL KEEP AREAS OF DRIZZLE AND LOW CIGS IN
PLACE. SOME GUIDANCE SUGGESTS DENSE FOG COULD FORM TOWARDS THE
END OF THE TAF PERIOD...BUT CONFIDENCE IS LOW THIS FAR OUT. WINDS
WILL BE ALL OVER THE PLACE TODAY AS WEAK LOW PRESSURE RIDES ALONG
THE LINGERING WEDGE FRONT. WINDS WILL REMAIN WELL BELOW 12 KT.
AMENDMENTS WILL MOST CERTAINLY BE ISSUED THROUGHOUT THE DAY AS
RADAR...VSBYS AND CIG TRENDS BECOME MORE APPARENT.

EXTENDED AVIATION OUTLOOK...VFR/IFR CONDITIONS ARE EXPECTED TONIGHT
THROUGH THURSDAY EVENING AS A SERIES OF LOW PRESSURE SYSTEMS MOVE
THROUGH THE AREA. SHOULD SEE VFR CONDITIONS RETURN AFTER MIDNIGHT
THURSDAY AND CONTINUE THROUGH THE WEEKEND AND INTO EARLY NEXT WEEK.

&&

.MARINE...
THERE ARE NO MAJOR CONCERNS THROUGH TONIGHT AS BOTH WINDS AND SEAS
WILL REMAIN WELL BELOW FLAG THRESHOLDS. WIND DIRECTIONS WILL BE
TRICKY TODAY AS LOW PRESSURE APPROACHES FROM THE WEST AND A
WARM FRONT APPROACHES THE COAST. A WEDNESDAY MORNING UPDATE
ADDRESSED THE LATEST PROGRESS OF THE WARM FRONT.

OTHERWISE...RAIN WILL BE LOCALLY HEAVY AT TIMES TODAY WITH VSBYS
DROPPING TO LESS THAN 1 NM. FOG/STRATUS IS LIKELY TONIGHT ACROSS
THE NEARSHORE WATERS.

THURSDAY THROUGH MONDAY...AN AREA OF LOW PRESSURE WILL TRACK OVER OR
JUST EAST OF THE WATERS ON THURSDAY. HIGH PRESSURE WILL THEN BRIEFLY
BUILD BACK IN THURSDAY NIGHT...BEFORE A COLD FRONT APPROACHES FROM
THE WEST ON FRIDAY. THE COLD FRONT WILL THEN PUSH THROUGH THE WATERS
FRIDAY NIGHT...WITH HIGH PRESSURE BUILDING BACK INTO THE REGION OVER
THE WEEKEND AND INTO EARLY NEXT WEEK.

COULD SEE SOME MARGINAL SMALL CRAFT CONDITIONS ACROSS PORTIONS OF
THE WATERS FRIDAY NIGHT AND SATURDAY BEHIND THE COLD FRONT.
OTHERWISE WINDS AND SEAS ARE EXPECTED TO REMAIN BELOW ADVISORY
THRESHOLDS.

&&

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