SOUTH CENTRAL BERKELEY...WESTERN CHARLESTON AND SOUTHEASTERN
DORCHESTER COUNTIES...

AT 1040 AM EST...NATIONAL WEATHER SERVICE DOPPLER RADAR CONTINUED TO 
INDICATE AN AREA OF MODERATE TO HEAVY RAIN CAPABLE OF PRODUCING 
FLASH FLOODING. THE HEAVIEST RAIN WAS LOCATED IN THE 
SUMMERVILLE...LADSON AND GOOSE CREEK AREAS WHERE RAINFALL RATES OF 1 
TO 2 INCHES PER HOUR ARE OCCURRING. ELSEWHERE IN THE WARNED 
AREA...RAINFALL RATES ARE GENERALLY 1/2 TO 1 INCH PER HOUR. 

THIS MUCH RAINFALL WILL BE SUFFICIENT TO PRODUCE FLASH FLOODING... 
ESPECIALLY IN LOW LYING AND POOR DRAINAGE AREAS. IN ADDITION...ROAD 
CLOSURES ARE VERY LIKELY IN SOME AREAS...ESPECIALLY IN DOWNTOWN 
CHARLESTON WHERE SOME STREETS ARE ALREADY FLOODED.

THE RAIN WILL BEGIN TO TAPER OFF FROM THE SOUTHWEST THROUGH MIDDAY.

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

.SYNOPSIS...
A WEDGE OF HIGH PRESSURE WILL GIVE WAY TO A STRONG WARM FRONT THIS MORNING
AS A SECONDARY AREA OF LOW PRESSURE DEVELOPS TO THE NORTHWEST. A COLD
FRONT TRAILING FROM THIS LOW WILL SWEEP THROUGH THE AREA FROM THE WEST
DURING THE LATE MORNING AND AFTERNOON HOURS. IN THE WAKE OF THE COLD
FRONT...MUCH COOLER AND DRIER CONDITIONS WILL FILTER IN AND
PERSIST INTO THE WEEKEND. LOW PRESSURE WILL THEN DEVELOP OFF THE
SOUTHEAST COAST SUNDAY WITH WEAK HIGH PRESSURE BUILDING OVER THE
REGION INTO EARLY NEXT WEEK.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
TEMPS AND DEW POINTS CONTINUE TO RISE AHEAD OF THE ADVANCING WARM
FRONT IN SE GEORGIA NEAR THE ALTAMAHA. SPC HAS ISSUED A TORNADO
WATCH FOR PARTS OF SE GEORGIA THROUGH EARLY AFTERNOON. A BROKEN
SQUALL LINE IS CURRENTLY RACING THROUGH S GEORGIA.

AN INTENSE STORM SYSTEM WILL LIFT NORTHEAST OUT OF THE LOWER
MISSISSIPPI VALLEY AND INTO THE OHIO VALLEY TODAY. MEANWHILE...STRONG
DIVERGENT FLOW ALOFT ASSOCIATED WITH THE LEFT FRONT QUADRANT OF AN
IMPRESSIVE 145 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 LATER
THIS 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 MUCH THE AREA 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 RARE FOR THIS TIME OF YEAR. THE MCS TO
THE SW THIS MORNING MAY DISRUPT SOME OF THE POTENTIAL FOR HEAVIER
RAINS OVER S GEORGIA WITH THE UPSTREAM HEIGHT FALLS AND LOW LEVEL
MOISTURE CONVERGENCE INCREASING QPF AMOUNT TO THE W OF I-95 THROUGH
MID MORNING.

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 COULD BE BRIEFLY HIGH
AS 500-750 J/KG BUT LOW LEVEL LAPSE RATES DO NOT LOOK VERY GOOD.
SOME DISCRETE SUPERCELLS COULD DEVELOP WITHIN THE WARM SECTOR
OR MORE LIKELY JUST AHEAD OF A TRIPLE POINT CONFIGURATION RIDING
ALONG OR JUST E OF THE I-95 CORRIDOR EARLY THIS AFTERNOON. FROM THE
00Z RUN...MODELS GIVING MIXED SIGNALS WITH THE BEST MID LEVEL
ENVIRONMENT NOT ALIGNING VERY WELL WITH THE AXIS OF EARLY AFTERNOON
LOW LEVEL INSTABILITY POKING N ALONG AND E OF I-95. THE MOST
IMPRESSIVE FEATURES CONTINUE TO BE THE DEEP LAYERED SHEAR/0-1 KM
HELICITIES ALONG WITH AN IMPRESSIVE LEFT FRONT EXIT REGION OF THE
250 MB JET STRUCTURE. AT THIS POINT...WE DO NOT FEEL THAT PLAYING
UP OR DOWN THE POTENTIAL TODAY WILL ADD ANYTHING BENEFICIAL.
MULTI-PARAMETER SREF PRODUCTS SUGGEST POTENTIAL FOR BOWING LING
SEGMENTS AND POSSIBLE ISOLATED TORNADOES IN THIS ENVIRONMENT SO A
CAREFUL HOUR BY HOUR MESO WATCH WILL BE NEEDED TODAY.

AS THE WARM FRONT MOVES N AND INLAND TODAY...STILL MANY QUESTIONS
CONTINUE ON THE EVENTUAL FAR INLAND INTRUSION. WITH A 50-60 KT
LOW LEVEL JET MAX OFF THE BOUNDARY LAYER AROUND 975-925 MB ACROSS
THE CHARLESTON TRI-COUNTY AREA EARLY THIS AFTERNOON...TEMPS
REACHING THE LOWER 70S SHOULD PRODUCE AT LEAST 2-3 HOURS OF STRONG
S TO SW FLOW. THE SOILS ARE SATURATED AND WE ISSUED A WIND ADVISORY
OVER OUR MAXIMUM WIND GUST AREA THIS AFTERNOON. ELSEWHERE IT WILL
BECOME BREEZY TO WINDY TODAY AS A STRONG COLD FRONT UNDERCUTS THE
MOUNTAINS...NEAR ADVISORY CRITERIA MAY BE POSSIBLE IN SOME INLAND
AREAS AS WELL...ESPECIALLY UNDER THE LARGE MID LEVEL DRY SLOT TO
THE W OF I-95 LATER TODAY.

THE VAST ARRAY OF COMPLEXITIES IN THE FORECAST TODAY LED US
TO MAINTAIN PERSISTENCE ON TEMPS DESPITE THE UNCERTAINTIES AND
TIMING. WE CONTINUED TO END POPS FROM SW TO NE TOWARD DUSK.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH FRIDAY/...
TONIGHT...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 FRIDAY...A QUIET PERIOD OF WEATHER IS EXPECTED
OVER THE SOUTHEAST AS WEAK HIGH PRESSURE BUILDS FROM OUR WEST ALONG
THE SOUTHERN EDGE OF A CUTOFF LOW TRACKING FROM THE MIDWEST TO THE
NORTHEASTERN UNITED STATES. A TRANSITION TO A MUCH COOLER AND DRYER
PATTERN WILL OCCUR AS A WEAK SECONDARY COLD FRONT SHIFTS THROUGH THE
FORECAST AREA WEDNESDAY...FOLLOWED BY A CHANGE IN WESTERLY FLOW TO A
MORE NORTHWEST/NORTH FLOW INTO THURSDAY AND FRIDAY...AS THE DEEP LOW
TO OUR NORTH SHIFTS OFF THE NORTHEAST COAST. DESPITE MOSTLY SUNNY
SKIES AND WEAK DOWNSLOPING WINDS...TEMPS WILL STRUGGLE TO REACH THE
LOW/MID 60S WEDNESDAY...AND THEN UPPER 50S BY THURSDAY. OVERNIGHT
LOWS WILL RANGE IN THE UPPER 30S TO MID 40S WEDNESDAY AND LOW 30S TO
LOW 40S THURSDAY. BY FRIDAY...A LARGE MID/UPPER LVL TROUGH WILL
BEGIN DIGGING INTO THE CENTRAL UNITED STATES AS THE CUTOFF LOW TO
OUR NORTH SHIFTS FURTHER INTO THE WESTERN ATLANTIC. THIS SHOULD
RESULT IN FURTHER HEIGHT FALLS OVER THE SOUTHEAST AND EVEN COOLER
TEMPS THAN PREVIOUS DAYS. EXPECT HIGH TEMPS TO REACH THE LOW 50S
OVER MOST LOCATIONS.

LAKE WINDS...WE COULD SEE WINDS REACH LAKE WIND ADVISORY CRITERIA ON
LAKE MOULTRIE ON WEDNESDAY AS STRONG LOW LVL WINDS SHIFT OVER THE
LAKE. COOLER LAKE WATERS WOULD LIKELY LIMIT THE STRONGEST WINDS TO
LAKE SHORE LOCATIONS. A LAKE WIND ADVISORY MAY BE REQUIRED.

&&

.LONG TERM /FRIDAY NIGHT THROUGH MONDAY/...
A DEEP LOW TO OUR NORTH WILL SHIFT WELL INTO THE WESTERN ATLANTIC
THIS WEEKEND AS A HIGH AMPLITUDE TROUGH DIGS OVER THE CENTRAL
UNITED STATES AND THEN INTO THE SOUTHEASTERN UNITED STATES. DRY AND
COOLER CONDITIONS WILL RESULT OVER THE FORECAST AREA WITH OVERALL
HIGH TEMPS STRUGGLING TO REACH THE LOW 50S SATURDAY AND ESPECIALLY
SUNDAY. AN AREA OF LOW PRESSURE IS THEN EXPECTED TO DEVELOP ALONG A
REMNANT BOUNDARY OFF THE SOUTHEAST COAST SUNDAY AFTERNOON/EVENING AS
STRONG DIVERGENT FLOW FROM THE DIGGING MID/UPPER LVL TROUGH ALONG
WITH THE RIGHT REAR QUADRANT OF A STRONG 165 KT H25 JET SHIFT OFF
THE SOUTHEAST COAST. AT THIS TIME...IT APPEARS ANY PRECIP ACTIVITY
ASSOCIATED WITH THE DEVELOPING LOW WILL STAY OFFSHORE...BUT THERE
IS A CHANCE WE COULD SEE A FEW SHOWERS ALONG COASTAL COUNTIES IN
SOUTH CAROLINA BEFORE THE SFC LOW QUICKLY EJECTS NORTH/NORTHEAST
AWAY FROM THE AREA LATE SUNDAY INTO EARLY MONDAY. GIVEN CURRENTLY
FORECASTED LOWS ARE IN THE UPPER 20S/LOWER 30S AND 850MB TEMPS ARE
NEAR -5 C...WE WILL HAVE TO KEEP AN EYE OUT FOR FROZEN PRECIP
POSSIBILITIES SUNDAY NIGHT. WEAK HIGH PRESSURE WILL THEN BUILD INTO
THE REGION BEHIND THE DEPARTING LOW...WITH A GRADUAL WARMING TREND
INTO EARLY NEXT WEEK.

&&

.AVIATION /12Z TUESDAY THROUGH SATURDAY/...
IFR/LIFR CIGS ALONG THE COASTAL CORRIDOR ALONG WITH RAIN...SOME
HEAVY WITH EMBEDDED CONVECTION. THUNDER CHANCES REMAIN TOUCH AND
GO WITH FUTURE AMENDMENTS POSSIBLE. A WARM FRONT WILL SURGE N OF
THE TERMINALS LATER THIS MORNING WITH WINDS VEERING S. GUSTY SURFACE
WINDS EXPECTED BY LATE MORNING INTO THIS AFTERNOON WITH CIGS LIKELY
BECOMING MORE MVFR ALTHOUGH IFR CIGS MAY PERSIST AT KCHS INTO EARLY
AFTERNOON. VFR CONDITIONS EXPECTED BY AFTERNOON.

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

&&

.MARINE...
TONIGHT...THE PINCHING OF THE PRESSURE PATTERN WAS IMPRESSIVE OVERNIGHT
WITH GUSTS TO NEAR GALE FORCE AT TIMES FROM FOLLY BEACH SOUTH TO
FORT PULASKI. STRONG PRES FALLS CURRENTLY UNDERWAY WHICH WILL UNDERMINE
THE STRONGEST PINCHING EFFECTS. A WARM FRONT WILL LIFT ACROSS THE
WATERS THIS MORNING...WITH WINDS VEERING SOUTHERLY IN ITS WAKE.
SOLID SMALL CRAFT ADVISORY CONDITIONS ACROSS ALL WATERS BUT THE SOUTH
WINDS WILL BE LESS EFFICIENT IN MIXING DOWN FOR A WHILE TODAY OVER THE
COOLER SHELF WATERS. SEAS ARE VERY ELEVATED AND WE HAD TO RAISE SOME
FORECAST SEA HEIGHTS A BIT TODAY GIVEN PRE-DAWN OBSERVATIONS.

SOME GUSTS TO NEAR GALE FORCE ARE POSSIBLE NEAR THE GULF STREAM
TONIGHT WITH COLD AIR ADVECTION DEVELOPING AND DIRECTIONS VEERING FROM
SW TO W WITH TIME. 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 SATURDAY...WE SHOULD SEE WINDS/SEAS IMPROVE FOR A
12-18 HOUR PERIOD WEDNESDAY...LEADING TO A PERIOD OF BELOW SMALL
CRAFT ADVISORY LEVEL CONDITIONS FOR ALL WATERS. AN ALREADY ENHANCED
PRESSURE GRADIENT WILL THEN TIGHTEN FURTHER WEDNESDAY NIGHT ALONG
THE SOUTHERN EDGE OF A DEEP CUTOFF LOW TRACKING FROM THE MIDWEST TO
THE NORTHEASTERN UNITED STATES INTO EARLY WEEKEND. THE TIGHTENING
GRADIENT ALONG WITH COOLER AIR ADVECTING OFFSHORE WILL LIKELY RESULT
IN A PERIOD OF SMALL CRAFT ADVISORY WINDS FOR ALL WATERS BEYOND
10 NM FROM THE COAST WEDNESDAY NIGHT INTO EARLY FRIDAY...AND FOR A
SMALLER TIME FRAME IN THE CHARLESTON HARBOR ON THURSDAY WHEN
40-50 KT LOW LVL WINDS SHIFT OFFSHORE. EXPECT A SOLID 20-25 KT WIND
OVER ALL WATERS WITH SEAS UP TO 5-7 FT...HIGHEST OVER OUTER GEORGIA
WATERS. CONDITIONS SHOULD THEN IMPROVE FRIDAY AFTERNOON INTO
SATURDAY AS THE DEEP LOW TO OUR NORTH SHIFTS FURTHER INTO THE
WESTERN ATLANTIC AND RESULTS IN A WEAKER PRESSURE GRADIENT AND LOW
LVL WIND FIELD OVER THE WATERS.

&&

.TIDES/COASTAL FLOODING...
STRONG ONSHORE FLOW OVERNIGHT HAD LED TO LARGE POSITIVE TIDAL DEPARTURES
AND HIGH TIDE THIS MORNING MAY NEAR COASTAL FLOOD ADVISORY CRITERIA
IN DOWNTOWN CHARLESTON...WITH SLIGHTLY LESSER CHANCES FOR CRITERIA
IN COASTAL CHATHAM COUNTY.
