AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHARLESTON SC
659 AM EST THU DEC 11 2008
.SYNOPSIS...
AN AREA OF LOW PRESSURE WILL MOVE NORTHEASTWARD TO WEST OF THE
AREA TODAY...PULLING A COLD FRONT THROUGH THE AREA THIS EVENING.
HIGH PRESSURE WILL BUILD IN BEHIND THE FRONT FOR FRIDAY AND THE
WEEKEND. A WEAK COASTAL TROUGH MAY FORM MONDAY...THEN DISSIPATE
TUESDAY AS A WEAK COLD FRONT APPROACHES FROM THE WEST AND STALLS
NORTH OF THE AREA WEDNESDAY.
&&
.NEAR TERM /UNTIL 6 PM THIS EVENING/...
CURRENTLY AT THE SURFACE A 998 MB AREA OF LOW PRESSURE IS LOCATED
OVER THE SOUTHERN ALABAMA WITH A COLD FRONT EXTENDING SOUTHWARD
INTO THE CARIBBEAN SEA. INFRARED SATELLITE IMAGERY SHOWS CLOUDY
SKIES IN PLACE ACROSS THE FORECAST AREA...WITH SHOWERS REMAINING
PRIMARILY ACROSS FAR WESTERN PORTIONS OF THE CWA AND ALONG SOUTH
CAROLINA COASTAL ZONES. MAIN NEAR TERM CONCERNS FOR TODAY REVOLVE
AROUND SEVERE THUNDERSTORM POTENTIAL AND WINDS.
TODAY...
THE STRONG UPPER LEVEL LOW OVER SOUTHERN LOUISIANA WILL TAKE ON A
NEGATIVE TILT AS IT PULLS INTO THE SOUTHEASTERN UNITED STATES. THIS
WILL ALLOW THE AREA OF LOW PRESSURE OVER THE NORTHERN GULF COAST TO
INTENSIFY AS IT TRACKS THROUGH CENTRAL GEORGIA AND EVENTUALLY INTO
THE WESTERN CAROLINAS BY THIS EVENING. DEEPEST MOISTURE AND BEST
FORCING WILL FOCUS PRIMARILY ACROSS FAR WESTERN ZONES THIS
MORNING...THEN EXPAND FROM SOUTHWEST TO NORTHEAST THIS AFTERNOON.
WILL CARRY CATEGORICAL POPS ALL AREAS TODAY...WITH HIGHEST POPS IN
THE MORNING ACROSS SOUTHEAST GEORGIA AND THIS AFTERNOON ACROSS
SOUTHERN SOUTH CAROLINA.
AS FOR SEVERE THUNDERSTORM POTENTIAL...INFRARED SATELLITE AND RADAR
IMAGERY ARE ALREADY BEGINNING TO SHOW SIGNS OF A SQUALL LINE
DEVELOPING FROM CENTRAL ALABAMA SOUTHWARD INTO THE SOUTHERN GULF OF
MEXICO. AS THE STORM SYSTEM CONTINUES TO INTENSIFY TO THE WEST OF
THE AREA THIS MORNING...EXPECT THAT THE SQUALL LINE WILL CONTINUE TO
GET BETTER ORGANIZED AS IT APPROACHES FROM THE WEST. THAT SAID...THE
ADDITION OF MINIMAL SURFACE HEATING AND INCREASING LOW LEVEL WIND
FIELDS RAISES CONCERNS THAT A DECENT SEVERE WEATHER OUTBREAK MAY
MATERIALIZE ACROSS THE FORECAST AREA...AND ESPECIALLY ACROSS
SOUTHERN SOUTH CAROLINA. LOW AND MID LEVEL WIND FIELDS WILL BE
IMPRESSIVE...WITH H95 TO H85 WINDS INCREASING TO 45 TO 55 KT AND H5
WINDS INCREASING TO 65 TO 75 KT BY 18Z. THIS IN COMBINATION WITH
MARGINAL H7 TO H5 LAPSE RATES OF 6 TO 6.5 C/KM IN A HIGHLY SHEARED
ENVIRONMENT WITH 0-6 KM BULK SHEAR VALUES OF 50 TO 60 KT WILL BE
SUPPORTIVE OF ORGANIZED CONVECTION. THE BIG QUESTION WILL BE HOW
MUCH INSTABILITY WILL BE REALIZED AS DYNAMICS WILL BE QUITE
IMPRESSIVE. GIVEN TEMPERATURES ALREADY AROUND 70 DEGREES AND
DEWPOINTS IN THE MID TO UPPER 60S...EXPECT THAT HIGHS WILL REACH THE
LOW TO MID 70S ACROSS THE VAST MAJORITY OF THE AREA BEFORE A SQUALL
LINE PUSHES THROUGH. THAT SAID...ADJUSTING MODEL SOUNDINGS FOR
FORECAST MAX TEMPERATURES ACTUALLY YIELDS CAPE VALUES OF 1000-1500
J/KG AND LI/S OF -3 TO -4. THIS INCREASES THE CONCERN THAT WE MAY BE
DEALING WITH A SEVERE WEATHER OUTBREAK ACROSS SOUTHEAST GEORGIA AND
SOUTHERN SOUTH CAROLINA FROM LATE THIS MORNING INTO THE AFTERNOON.
THE MAIN HAZARD WILL BE STRONG DAMAGING WINDS WITH ANY SEVERE
THUNDERSTORMS THAT DEVELOP...HOWEVER AN ISOLATED TORNADO AND
MARGINALLY SEVERE HAIL CAN/T BE RULED OUT GIVEN 0-1 KM HELICITY
VALUES OF 200-300 M2/S2 AND WET BULB ZERO HEIGHTS OF 11 TO 12 KFT.
STRONG WINDS...
GIVEN STRONG WIND FIELDS OF 40 TO 50 KT DEVELOPING FROM MID MORNING
THROUGH EARLY AFTERNOON BETWEEN 1 AND 2 KFT AGL...AM A BIT CONCERNED
THAT SURFACE WINDS MAY REACH WIND ADVISORY CRITERIA FOR SEVERAL
HOURS...PRIMARILY ALONG AND EAST OF A LINE EXTENDING FROM BEAUFORT
COUNTY NORTHWARD INTO WESTERN BERKELEY COUNTY AND AWAY FROM THE
IMMEDIATE COAST. WILL HOLD OFF ON ISSUING A WIND ADVISORY AT THIS
TIME AND RE-EVALUATE AS THE DATA FROM THE MORNING KCHS RAOB COMES
IN.
LAKE WINDS...
LOW LEVEL WIND FIELDS WILL STRENGTHEN QUICKLY THIS MORNING OVER LAKE
MOULTRIE. ALTHOUGH THE COOLER WATERS MAY DIMINISH SOME OF THE WIND
ENERGY OVER THE MIDDLE OF THE LAKE...EXPECT LAKE WIND ADVISORY WINDS
TO BE SEEN CLOSER TO THE COAST...SO WILL KEEP THE ADVISORY IN TACT.
WILL ADJUST THE START TIME SEVERAL HOURS EARLIER HOWEVER...AS WINDS
SHOULD BEGIN TO GUST TO LAKE WIND CRITERIA BY MID MORNING.
&&
.SHORT TERM /6 PM THIS EVENING THROUGH 6 AM FRIDAY/...
THE STORM SYSTEM WILL TRACK FROM THE WESTERN CAROLINAS THIS EVENING
INTO SOUTHERN NEW ENGLAND BY FRIDAY MORNING...AND THIS WILL DRAG A
COLD FRONT THROUGH THE FORECAST AREA THIS EVENING. WILL CONTINUE TO
CARRY LIKELY POPS NORTH AND CHANCE POPS SOUTH THIS EVENING...THEN
TAPER TO CHANCE POPS NORTH AND DRY CONDITIONS SOUTH AFTER MIDNIGHT.
WILL CONTINUE TO MENTION THUNDER IN THE EVENING AS WELL WITH
IMPRESSIVE H5 TROUGH SWINGING OVERHEAD. OVERNIGHT LOWS WILL BE MUCH
COOLER THAN THE PAST SEVERAL NIGHTS...BOTTOMING OUT IN THE LOW TO
MID 40S ACROSS THE AREA.
LAKE WINDS...THERE MAY BE A BRIEF LULL IN WINDS OF LAKE MOULTRIE
FROM LATE THIS AFTERNOON THROUGH EARLY THIS EVENING PRIOR TO THE
COLD FRONTAL PASSAGE. ONCE THE COLD FRONT PUSHES THROUGH EXPECT
WINDS TO RAPIDLY INCREASE BY LATE THIS EVENING AS COLD AIR ADVECTION
POURS OVER THE LAKE...AND WILL KEEP THE LAKE WIND ADVISORY IN EFFECT
THROUGH MID MORNING FRIDAY.
&&
.LONG TERM /FRIDAY THROUGH WEDNESDAY/...
FAIRLY GOOD FORECAST CONFIDENCE THROUGH THE PERIOD. HIGH PRESSURE
WILL BUILD IN BEHIND A DEPARTING AREA OF LOW PRESSURE FRI...THEN SET
UP N AND NE OF THE AREA THROUGH THE WEEKEND. MEANWHILE A COASTAL
TROUGH WILL DEVELOP OFFSHORE SUN AND PUSH ONSHORE MON AS A COLD
FRONT APPROACHES FROM THE W. MAINLY A DRY FORECAST THROUGH THE
PERIOD OUTSIDE OF A FEW SHOWERS POSSIBLE WITH THE COASTAL TROUGH
SUN/MON AND THE APPROACHING FRONT WED. HOWEVER...PREFER TO LEAVE THE
FORECAST DRY FOR NOW. BELOW NORMAL TEMPS FRI THROUGH SAT NIGHT WILL
BECOME ABOVE NORMAL THEREAFTER INTO THE MIDDLE OF NEXT WEEK.
&&
.AVIATION /12Z THURSDAY THROUGH MONDAY/...
A FEW SHOWERS ARE STREAMING IN OFF THE ATLANTIC THIS MORNING AND
INTO THE CHS TERMINAL...WITH A MUCH BIGGER RAIN SHIELD SOUTH AND
WEST OF THE TERMINALS. THIS RAIN SHIELD WILL AFFECT THE TERMINALS
LATER TODAY.
VERY DIFFICULT TAF FORECAST THIS MORNING...WITH IFR CIGS IN PLACE
ACROSS MUCH OF COASTAL SOUTHEAST GEORGIA AND IMPACTING THE SAV
TERMINAL. ACROSS THE REST OF THE AREA INCLUDING THE CHS
TERMINAL...MVFR CONDITIONS ARE GENERALLY THE RULE. AS LOW LEVEL
WIND FIELDS STRENGTHEN AND BECOME MORE SOUTHERLY...SHOULD SEE CIGS
RISE TO MVFR LEVELS BY MID MORNING AT THE SAV TERMINAL AND REMAIN
IN THE MVFR RANGE AT THE CHS TERMINAL. THE STRONG WIND FIELDS
ALOFT WILL ALSO CREATE GUSTY CONDITIONS AT THE TERMINAL...ALREADY
EVIDENT IN THE OBSERVATIONS AT SAV. THIS WILL CONTINUE THROUGH MID
TO LATE AFTERNOON BEFORE PRESSURE GRADIENT SLACKENS.
AS FOR THUNDER POTENTIAL...THE DEEPENING CYCLONE TO THE WEST OF
THE AREA WILL TRACK NORTHEASTWARD THROUGH CENTRAL GEORGIA AND
INTO THE WESTERN CAROLINAS THIS AFTERNOON. GIVEN WARM AND MOIST
LOW LEVELS AND STRENGTHENING UPPER LEVEL FORCING...EXPECT THE LINE
OF SHOWERS AND THUNDERSTORMS TO THE SOUTH AND WEST TO REMAIN IN
TACT AS IT APPROACHES THE TERMINALS. HAVE BROUGHT RAIN CHANCES IN
BY LATE MORNING AT THE SAV TERMINAL AND A COUPLE HOURS LATER IN
THE EARLY AFTERNOON AT THE CHS TERMINAL. HAVE OPTED TO INCLUDE
SOME STRONGER GUSTS IN A TEMPO TSRA GROUP AT BOTH TERMINALS GIVEN
STRENGTH OF LOW LEVEL WIND FIELDS. DON/T EXPECT SHOWERS/TSTMS TO
END RIGHT AWAY BEHIND THE SQUALL LINE GIVEN STRONG FORCING FOR
ASCENT AND LINGERING HIGH DEWPOINT AIR...SO HAVE MAINTAINED
MENTION OF SHRA OR VCSH INTO THE EVENING AND OVERNIGHT. MODEL
SOUNDINGS AND RELATIVE HUMIDITY TIME SECTIONS INDICATE THAT MVFR
CIGS WILL LIKELY HANG AROUND THROUGH THE REMAINDER OF THE TAF
FORECAST PERIOD.
EXTENDED AVIATION...A COLD FRONT WILL MOVE OFFSHORE FRI MORNING
FOLLOWED BY HIGH PRES OVER THE WEEKEND WHICH WILL MAKE FOR
PREVAILING VFR CONDITIONS.
&&
.MARINE...
UPDATE...A TORNADO WATCH HAS BEEN ISSUED FOR THE NEARSHORE GA
WATERS UNTIL NOON.
AN AREA OF LOW PRESSURE OVER THE WESTERN FLORIDA PANHANDLE WILL
INTENSIFY AS IT PULLS NORTHEAST THROUGH CENTRAL GEORGIA AND INTO THE
WESTERN CAROLINAS BY THIS EVENING. THE STORM SYSTEM WILL THEN
CONTINUE TO MOVE OFF TO THE NORTHEAST AND INTO SOUTHERN NEW ENGLAND
BY FRIDAY MORNING. STRONG LOW LEVEL WIND FIELDS WILL DEVELOP IN
RESPONSE TO THE STRENGTHENING STORM SYSTEM...RESULTING IN SMALL
CRAFT CONDITIONS ACROSS ALL WATERS AND GALE FORCE WINDS ACROSS THE
OUTER GEORGIA WATERS. GOING HEADLINES LOOK IN GOOD SHAPE...AND ONLY
ALTERATION WILL BE TO EXTEND SMALL CRAFTS INTO MID MORNING FRIDAY.
SLOWLY IMPROVING MARINE CONDITIONS FRI AND FRI NIGHT AS LOW PRES
EXITS THE NC/VA COAST AND HIGH PRES MOVES INTO THE AREA FROM THE
W. SEAS WILL BEGIN TO BUILD AGAIN OVER THE WEEKEND THOUGH AS HIGH
PRES BUILDS N OF THE AREA ALLOWING A FAVORABLE NE FETCH TO SET UP.
A WEAK COASTAL TROUGH LOOKS TO DEVELOP EARLY NEXT WEEK WHILE THE
HIGH PRES SETTLES OFF THE SRN NEW ENGLAND COAST. AN EXTENDED
PERIOD OF SMALL CRAFT ADVISORIES ARE LIKELY BEGINNING LATE
SAT...MAINLY FOR SEAS.
&&
.HYDROLOGY...
WITH HEAVY RAINFALL ANTICIPATED ACROSS GA...EXPECT A RISE IN RIVER
LEVELS INTO THE WEEKEND...WITH THE LATEST FORECAST FROM THE SE
RIVER FORECAST CENTER INDICATING REIDSVILLE ON THE OHOOPEE RIVER
MAY GET WITHIN A HALF FOOT OF FLOOD STAGE SUN MORNING.
&&
.TIDES/COASTAL FLOODING...
ONSHORE FLOW IN COMBINATION WITH ASTRONOMICAL HIGH TIDES...EASTERLY
SWELL...MAY PUSH TIDE LEVELS SLIGHTLY ABOVE SHALLOW COASTAL FLOODING
CRITERIA ALONG THE SOUTH CAROLINA AND GEORGIA COASTS DURING THIS
MORNINGS HIGH TIDE. ASTRONOMICAL TIDE LEVELS IN CHS AND SAV ARE 6.6
MLLW AND 8.5 MLLW RESPECTIVELY BETWEEN 6 AND 7 AM THIS MORNING...AND
WITH AROUND A HALF FOOT DEPARTURE EXPECTED...SHALLOW COASTAL
FLOODING SHOULD BE REACHED. AS A RESULT...A COASTAL FLOOD ADVISORY
WILL REMAIN IN EFFECT FOR THE PERIOD BETWEEN 4 AM AND 9 AM THURSDAY
MORNING.
WE MAY ALSO BE DEALING WITH MORE SHALLOW COASTAL FLOODING OVER THE
WEEKEND AND INTO EARLY NEXT WEEK WITH ASTRONOMICALLY HIGH TIDES
AND ONSHORE WINDS.
