AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHARLESTON SC
115 AM EST TUE FEB 26 2013

.SYNOPSIS...
A WEDGE OF HIGH PRESSURE WILL PERSIST...BEFORE A WARM FRONT LIFTS
NORTH INTO THE AREA LATE TONIGHT INTO TUESDAY MORNING AS AN AREA OF
LOW PRESSURE PASSES TO THE NORTHWEST. A COLD FRONT TRAILING FROM
THIS LOW WILL THEN SWEEP THROUGH THE AREA FROM THE WEST DURING THE
LATE MORNING AND AFTERNOON ON TUESDAY. IN THE WAKE OF THE COLD
FRONT...MUCH COOLER AND DRIER CONDITIONS WILL FILTER IN AND PERSIST
INTO THE UPCOMING WEEKEND.

&&

.NEAR TERM /UNTIL 6 AM THIS MORNING/...
AN EXPANDING AREA OF RAINS WILL CONTINUE TO SPREAD IN FROM THE
SOUTH AND SW. THIS IS IN ASSOCIATION WITH A MID LEVEL SHORT
WAVE...AIDED BY THE NOSE OF A 120 KT OR GREATER UPPER LEVEL JET
THAT WRAPS AROUND THE SOUTH AND SE SIDE OF THE POTENT CYCLONE
ALOFT OVER THE ARKLATEX AREA. THIS LARGE SCALE FORCING FOR
ASCENT...COMBINED WITH STRENGTHENING LOW LEVEL CONVERGENCE AS
WINDS JUST OFF THE DECK VEER AROUND TO THE SE AND SOUTH BY
MORNING. WINDS IN THIS LAYER WILL BE AS HIGH AS 40-50
KT...ALTHOUGH SURFACE WINDS WILL BE SLOWER IN VEERING. A WARM
FRONT LOCATED SOUTH OF THE ZONES LATE MONDAY EVENING WILL LIFT
NORTHWARD THROUGH THE NIGHT...REACHING THE COASTAL COUNTIES BY
AROUND 09Z...THEN PROGRESSING THROUGH ABOUT THE EASTERN 1/3 OF THE
CWFA BY MORNING. AS PWATS CLIMB TO NEAR THE 99TH PERCENTILE IN
MOST AREAS LATE...SOME OF THE RAIN WILL BECOME HEAVY AT
TIMES...RESULTING IN MINOR FLOODING OF POOR DRAINAGE LOCATIONS.

RAIN COVERAGE WILL INCREASE FROM SW TO NE THROUGH THE
NIGHT...RANGING FROM 20 PERCENT FAR NORTH TO 80 PERCENT FAR SOUTH
BY MIDNIGHT. THEN UP TO CATEGORICAL IN ALL ZONES AS TIMES
PROGRESSES OVERNIGHT. STILL NO SIGNS OF ANY SURFACE BASED
INSTABILITY AS PER THE SPC MESO-ANALYSIS...BUT SHOWALTER VALUES DO
DROP TO NEAR ZERO LATE...SO WE HAVE MAINTAINED THE RISK OF
ISOLATED T-STORMS AFTER 07Z.

VARIOUS OBSERVATION SITES HAVE BEEN SHOWING LIGHT FOG...WITH EVEN
SOME POCKETS OF DENSE FOG TRYING TO FORM. IN ADDITION...THE FLOW
JUST OFF THE SURFACE WILL VEER TO THE SE AND SOUTH OVERNIGHT AS
TEMPS THROUGHOUT MUCH OF THE VERTICAL EXPERIENCE SIGNIFICANT WARM
ADVECTION. WITH THIS OVER-RIDING AIR ATOP THE COOLER AND MOIST
GROUNDS...FOG MAY BECOME A LITTLE MORE OF A PROBLEM. THUS WE HAVE
ADDED PATCHY FOG TO THE FORECAST.

NE AND EAST WINDS WILL AVERAGE 10-20 MPH THROUGH THE NIGHT...BUT
COASTAL SECTIONS WILL EXPERIENCE SOME GUSTS AS HIGH AS 30 MPH WHERE
THE PINCHED PRESSURE GRADIENT PERSISTS.

THE TEMP CURVE WILL CERTAINLY BE A DIFFICULT ASPECT TO THE
FORECAST. WE/LL BE AT OUR LOWEST PRIOR TO 07Z...RANGING FROM THE
LOWER 40S NORTH AND WEST TO THE UPPER 40S AND LOWER 50S SOUTH AND
EAST. BY 12Z OUR 850 MB TEMPS CLIMB BY SOME 3-4C AND THE 1000-850
MB THICKNESS RISES A GOOD 25-30 METERS. THUS WE LOOK FOR RISING
TEMPS LATE...AND WE/LL BE A GOOD 8-15 DEGREES WARMER NEAR THE
COAST AND 4-8 DEGREES HIGHER INLAND BY 6 AM.

&&

.SHORT TERM /6 AM THIS MORNING THROUGH THURSDAY/...
TUESDAY...AN INTENSE STORM SYSTEM WILL LIFT NORTHEAST OUT OF THE
LOWER MISSISSIPPI VALLEY AND INTO THE OHIO VALLEY. MEANWHILE...
STRONG DIVERGENT FLOW ALOFT ASSOCIATED WITH THE LEFT FRONT QUADRANT
OF AN IMPRESSIVE 135 KT JET AT H25 WILL CAUSE A SECONDARY LOW TO
FORM OVER NORTH-CENTRAL GEORGIA IN THE MORNING...THEN TRACK
NORTHEAST ACROSS THE MIDLANDS OF SOUTH CAROLINA THROUGH THE
AFTERNOON. AS THIS OCCURS...A WARM FRONT WILL LIFT NORTH ACROSS THE
AREA TUESDAY MORNING ERODING THE IN-SITU WEDGE AND ALLOWING THE WARM
SECTOR TO OVERSPREAD THE AREA WITH DEWPOINTS SURGING WELL INTO THE
LOWER 60S. A COLD FRONT TRAILING THE SECONDARY LOW WILL THEN QUICKLY
SWEEP THROUGH THE AREA FROM LATE MORNING THROUGH MID AFTERNOON BASED
ON MODEL CONSENSUS. GIVEN THE MAGNITUDE OF WARM AIR
ADVECTION...DAYTIME TEMPERATURES SHOULD REACH INTO THE LOWER TO MID
70S IN MOST AREAS ONCE THE WARM SECTOR DEVELOPS.

SHOWERS WILL BE WIDESPREAD ACROSS THE AREA IN THE MORNING AS STRONG
ISENTROPIC ASCENT WILL BE ONGOING AS THE WARM FRONT LIFTS THROUGH.
THE RAIN WILL BE HEAVY AT TIMES AS WELL...WITH PRECIPITABLE WATER
VALUES AS HIGH AS 1.7 INCHES WHICH IS EXTREMELY RARE FOR THIS TIME
OF YEAR. THERE COULD THEN BE SOME BREAKS IN THE SHOWERS WITH THE
COVERAGE EXPECTED TO BE MORE NUMEROUS IN ADVANCE OF THE COLD FRONT
DURING THE LATE MORNING AND EARLY AFTERNOON. SHOWERS WILL THEN TAPER
OFF FROM THE WEST IN WAKE OF THE COLD FRONT DURING THE MID TO LATE
AFTERNOON HOURS.

THE FOCUS THEN TURNS TO THE SEVERE WEATHER POTENTIAL...WITH THE
STORM PREDICTION CENTER KEEPING THE AREA IN A SLIGHT RISK FOR SEVERE
THUNDERSTORMS. THE SEVERE THREAT IS CONDITIONAL ON THE
TIMING...EXTENT AND OVERALL QUALITY OF THE WARM SECTOR WHICH WILL
ULTIMATELY DETERMINE THE AMOUNT OF AVAILABLE INSTABILITY. GIVEN THE
FORECAST TEMPERATURES AND DEWPOINTS...SURFACE BASED CAPE IS EXPECTED
TO BE AS HIGH AS 500-750 J/KG. SOME DISCRETE SUPERCELLS COULD
DEVELOP WITHIN THE WARM SECTOR...WITH A SQUALL LINE THEN EXPECTED TO
PROGRESS THROUGH THE AREA AHEAD OF THE COLD FRONT. THE CONCERN IS
THAT WITH THE SECONDARY LOW PASSING JUST TO THE WEST THAT STRONG
DEEP LAYERED SHEAR WILL DEVELOP OVER THE AREA WITH MODEL SOUNDINGS
SHOWING IMPRESSIVE HODOGRAPHS. IN FACT...THE SPC SREF INDICATES HIGH
PROBABILITIES OF BULK SHEAR VALUES OVER 50 KT AND 0-3KM HELICITY
OVER 300 M2/S2. IN ADDITION...THE SUPERCELL COMPOSITE PARAMETER AND
SIGNIFICANT TORNADO PARAMETER ARE ALSO VERY HIGH. THESE VALUES ALL
INDICATE THE POTENTIAL FOR TORNADIC STORMS TO DEVELOP IF THE
INSTABILITY MATERIALIZES. THERE IS ALSO A THREAT FOR DAMAGING WINDS
WITH A 50 KT LOW LEVEL JET ADVANCING OVER THE AREA. THE BEST TIMING
FOR SEVERE THUNDERSTORMS APPEARS TO BE FROM MID MORNING THROUGH
EARLY AFTERNOON. EVEN OUTSIDE OF THUNDERSTORMS...WINDS WILL BE
STRONG WITH GUSTS UPWARDS OF 30-35 MPH AT TIMES WHICH IS JUST SHY OF
WIND ADVISORY CRITERIA.

TUESDAY NIGHT...THE COLD FRONT WILL CONTINUE TO PROGRESS OFFSHORE
WITH COOLER/DRIER AIR ADVECTING INTO THE REGION ON A SOUTHWEST-WEST
FLOW. COLD AIR ADVECTION WILL LIKELY KEEP WINDS COUPLED IN MOST
LOCATIONS AND THIS SHOULD ONLY ALLOW TEMPERATURES TO FALL TO LOWS IN
THE MID 40S ACROSS MUCH OF THE AREA.

WEDNESDAY THROUGH THURSDAY...A LARGE CLOSED UPPER LOW WILL CONTINUE
TO DEEPEN AND PASS BY WELL TO THE NORTH OF THE FORECAST AREA THROUGH
THURSDAY. THE DEPARTING COLD FRONT ASSOCIATED WITH THE DOUBLE BARREL
SURFACE LOW OVER THE GREAT LAKES AND THE MID ATLANTIC WILL PUSH
FURTHER OFFSHORE WITH A SECONDARY FRONT PASSING THROUGH WEDNESDAY
AFTERNOON WITH A COOLER SHOT OF AIR. OVERALL WEDNESDAY AND THURSDAY
WILL BE RELATIVELY QUIET. WEDNESDAY WILL BE THE WARMEST AHEAD OF THE
SECONDARY FRONT WITH HIGHS IN THE MID 60S. THURSDAY WILL BRING TEMPS
5-6 DEGREES BELOW CLIMO...ONLY REACHING THE UPPER 50S. WITH THE
PERSISTENT TIGHT PRESSURE GRADIENT AROUND THE LOW TO THE NORTH WILL
ALSO RESULT IN BREEZY CONDITIONS EACH DAY. SKIES WILL BE MOSTLY
CLEAR TO PARTLY CLOUDY...DEPENDING ON THE AMOUNT OF HIGH CLOUDS
PASSING OVERHEAD.

LAKE WINDS...A LAKE WIND ADVISORY HAS BEEN ISSUED FOR LAKE MOULTRIE
BEGINNING LATE TUESDAY MORNING WHEN THE WEDGE OF HIGH PRESSURE IS
EXPECTED TO ERODE AND STRONG MIXING DEVELOP AS A WARM FRONT LIFTS
THROUGH. WINDS WILL REMAIN ELEVATED UNTIL AT LEAST TUESDAY EVENING.

&&

.LONG TERM /THURSDAY NIGHT THROUGH MONDAY/...
A DEEP LOW WILL TRACK FROM THE MIDWEST TO THE NORTHEASTERN UNITED
STATES BEFORE SHIFTING OFFSHORE THIS WEEKEND. THIS WILL RESULT IN
MAINLY A DRY AND COOLING TREND OVER THE SOUTHEASTERN UNITED STATES
THROUGH EARLY NEXT WEEK. MODELS SUGGEST A LARGE MID LVL TROUGH
DIGGING OVER THE EASTERN CONUS THROUGH THE WEEKEND WITH A COOL
NORTHWEST FLOW INTO THE AREA. OVERALL HIGH TEMPS SHOULD RANGE IN THE
LOW/MID 50S WITH COOLEST TEMPS EXPECTED ON SATURDAY AND SUNDAY.
OVERNIGHT LOWS SHOULD RANGE IN THE LOW/MID 30S...WITH SOME UPPER 20S
POSSIBLE OVER INLAND AREAS SATURDAY/SUNDAY NIGHT.

&&

.AVIATION /06Z TUESDAY THROUGH SATURDAY/...
KCHS...LIGHT RAINS AND DRIZZLE SHOULD BECOME MORE SUBSTANTIAL
LATE TONIGHT INTO MID MORNING AS A CONVEYOR BELT OF DEEP MOISTURE
SWINGS THROUGH. LLWS WILL LIKELY BE SEEN IN THE SAME TIME PERIOD.
IFR CIGS AND VSBYS MAY BECOME WIDESPREAD ONCE HEAVIER PCPN BEGINS.
LATER TODAY...CHANCES FOR CONVECTIVE RAINS AND STRONG AND GUSTY
SURFACE WINDS. MESOSCALE AND RADAR TRENDS WILL DICTATE MORE
SUBSTANTIAL CONVECTION THIS AFTERNOON. CLOUDS BEGINS TO BREAK
THIS EVENING.

KSAV...LIFR/IFR CIGS LIKELY TO CONTINUE OVERNIGHT BUT HEAVIER
RAINS AT TIMES COULD CAUSE SOME TEMPORARY INCREASES IN CIGS. LLWS
IS LIKELY THIS MORNING AS STRONG VEERING OCCURS IN THE LOWEST
LAYERS OF THE ATMOSPHERE. SHOWERS WILL TAPER OFF THIS AFTERNOON AS
A POWERFUL MID LEVEL DRY SLOT PUNCHES IN FROM THE SW. SURFACE
WINDS WILL VEER TO SW AND BECOME GUSTY AS A WARM FRONT LIFTS N OF
THE TERMINAL. VFR CONDITIONS ARE EXPECTED TO PREVAIL BY LATE TODAY
INTO THIS EVENING.

EXTENDED AVIATION OUTLOOK...VFR CONDITIONS WILL PREVAIL THROUGH
LATE IN THE WEEK. WINDS WILL BE GUSTY AT TIMES EACH AFTERNOON
THROUGH THURSDAY.

&&

.MARINE...
TONIGHT...THE PINCHING OF THE PRESSURE PATTERN WILL PERSIST
TONIGHT...BETWEEN THE INLAND WEDGE AND THE WARM FRONT THAT WILL
SLOWLY ATTEMPT TO MOVE NORTH AND NW ACROSS THE GULF STREAM
THROUGH THE NIGHT. NE AND EAST WINDS OF 20-30 KT EARLY WILL VEER
MORE TOWARD THE EAST AND SE WITH THE PASSAGE OF THE WARM FRONT
LATER TONIGHT...WITH SIMILAR SPEEDS. WHILE WE CANNOT RULE OUT SOME
GUSTS TO NEAR 35 KT OR GALE FORCE...THEIR INFREQUENCY PREVENT US
FROM ISSUING A GALE WARNING. SEAS WILL BE AS HIGH AS 5-7 FT WITHIN
20 NM OF THE COAST...7-9 FT ACROSS THE OUTER GA WATERS AND EVEN 2
FT OR SO IN CHARLESTON HARBOR. WHILE WE STILL FEEL THAT THE STRONG
WIND FIELDS WILL PREVENT SIGNIFICANT FOG FROM DEVELOPING...WE ARE
CONCERNED THAT WITH THE VERY WARM AIR JUST OFF THE SURFACE MOVING
ACROSS THE COOLER SHELF WATERS THAT A LITTLE FOG WILL FORM. THAT
ALONG WITH A LOW STRATUS DECK HAS FORCED US TO INCLUDE PATCHY FOG
WITH VISIBILITIES DOWN UNDER 3 NM TONIGHT FOR ALL BUT AMZ374.

TUESDAY THROUGH TUESDAY NIGHT...A WARM FRONT WILL LIFT ACROSS THE
WATERS DURING THE MORNING...WITH WINDS VEERING SOUTHERLY IN ITS
WAKE. DEEPER MIXING AND THE DEVELOPMENT OF A STRONG LOW LEVEL JET
WILL RESULT IN SOLID SMALL CRAFT ADVISORY CONDITIONS ACROSS ALL
WATERS...WITH GUSTS UPWARDS OF 30 KT POSSIBLE AT TIMES. WINDS WILL
BE LOCALLY HIGHER IN THUNDERSTORMS AS WELL. A COLD FRONT WILL PUSH
OFFSHORE DURING THE MID TO LATE AFTERNOON...WITH MORE OF AN OFFSHORE
COMPONENT DEVELOPING. SOME GUSTS TO NEAR GALE FORCE ARE POSSIBLE
NEAR THE GULF STREAM TUESDAY NIGHT WITH COLD AIR ADVECTION
DEVELOPING. CONDITIONS WILL GRADUALLY FALL BELOW SMALL CRAFT
ADVISORY CRITERIA DURING THE EVENING AND OVERNIGHT HOURS FOR ALL
NEAR SHORE MARINE ZONES INCLUDING THE CHARLESTON HARBOR.

WEDNESDAY THROUGH FRIDAY...A TIGHT PRESSURE GRADIENT AROUND LOW
PRESSURE TO THE NORTH WILL CONTINUE ACROSS THE LOCAL WATERS THROUGH
MUCH OF THE MID/LATE WEEK PERIOD. THIS TIGHT GRADIENT COMBINED WITH
COOLER AIR FILTERING IN WILL RESULT IN ELEVATED WINDS AND SEAS. THE
MAIN TIME PERIOD OF THE STRONGEST WINDS WILL BE WEDNESDAY NIGHT AS A
SECONDARY FRONT PASSES THROUGH WITH A STRONG LOW LEVEL JET. SMALL
CRAFT ADVISORIES WILL LIKELY BE NEEDED SOMETIME LATE WEDNESDAY
THROUGH A PORTION OF THURSDAY. CONDITIONS WILL QUIET DOWN FRIDAY AS
THE GRADIENT RELAXES.

     EVENING FOR SCZ045.
