AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHARLESTON SC
142 PM EDT SUN AUG 14 2011

.SYNOPSIS...
A COLD FRONT WILL APPROACH THE REGION FROM THE WEST LATE TODAY...
AND MOVE OFFSHORE AND INTO THE ATLANTIC LATE TONIGHT. HIGH
PRESSURE WILL THEN REBUILD OVER THE AREA THROUGH MUCH OF WEEK. A
WEAKENING COLD FRONT MAY APPROACH FROM THE NORTHWEST NEXT WEEKEND.

&&

.NEAR TERM /UNTIL MIDNIGHT/...
WATER VAPOR IMAGERY SHOWS THE PRONOUNCED LONGWAVE UPPER TROUGH
DIGGING ACROSS THE SOUTHEAST UNITED STATES WITH EMBEDDED VORT
MAXIMA. ONE SUCH VORT IS SHOWING UP OVER SOUTHWEST GA MOVING TO
THE EAST. OUR MORNING 12Z RAOB SHOWED 15-20 KT OF WESTERLY FLOW
JUST OFF THE DECK WHICH WILL KEEP THE SEABREEZE PINNED TO THE
COAST UNTIL MID TO LATE AFTERNOON ONCE THE FLOW BACKS TO SW.

THE LOW-LEVEL AIRMASS IS QUITE MOIST GIVEN SURFACE DEWPOINTS
HOVERING IN THE LOWER TO MIDDLE 70S. PRECIPITABLE WATER ON THE
MORNING SOUNDING WAS ABOUT 2 INCHES. HOWEVER...ALOFT WE SEE QUITE
A BIT OF DRY AIR WHICH IS CONCERNING FOR SEVERE WEATHER POTENTIAL.
THE DOWNDRAFT CAPE ON OUR MODIFIED SOUNDING WAS 1150 J/KG WITH A
DELTA THETA-E OF 36C. THESE VALUES ARE ON THE HIGH END FOR
DAMAGING WIND POTENTIAL IN OUR AREA THIS TIME OF YEAR. WE EXPECT
SEVERAL WEAK SHORTWAVES TO MOVE THROUGH THE AREA THIS AFTERNOON
AHEAD OF THE PRIMARY TROUGH AND SURFACE COLD FRONT WHICH WILL
SWING THROUGH LATER THIS EVENING. THE FIRST CONVECTION WILL LIKELY
BE FROM SHOWERS AND THUNDERSTORMS DEVELOPING INLAND AND MOVING
EAST INTO THE AREA. WITH 850-700 MB FLOW INCREASING TO 20-25 KT
THIS AFTERNOON AND BULK SHEAR BUILDING TO AROUND 20 KT...ORGANIZED
CONVECTION SEEMS QUITE LIKELY...ESPECIALLY BY LATE THIS AFTERNOON
INTO THE EVENING.

THE AFOREMENTIONED DRY AIR ALOFT INDICATES A CONSIDERABLE DAMAGING
WIND THREAT THIS AFTERNOON AND EVENING. THE LATEST DAY 1 OUTLOOK
FROM SPC PLACES MUCH OF OUR AREA WITHIN A 30 PERCENT WIND THREAT.
WE LAUNCHED AN 18Z SOUNDING WHICH SHOULD HELP SAMPLE THE PRE- STORM
ENVIRONMENT ONCE THE MID-LEVEL FLOW INCREASES AND WE ARE AT OUR
PEAK HEATING. WE ADDED SEVERE THUNDERSTORMS WITH DAMAGING WINDS TO
THE FORECAST PRODUCTS THIS AFTERNOON/EVENING. THE FRONT IS
EXPECTED TO SWEEP THROUGH DURING THE MID-EVENING... POSSIBLY
ACCOMPANIED BY A SQUALL LINE. HOWEVER...ASSUMING WE SEE QUITE A
BIT OF CONVECTION PRIOR TO THE FRONTAL PASSAGE...THE SEVERE
POTENTIAL WITH THE ACTUAL FRONT IS QUESTIONABLE.

&&

.SHORT TERM /MIDNIGHT TONIGHT THROUGH WEDNESDAY/...
MODELS SUGGEST THE COLD FRONT WILL TAKE MOST OF THE DEEPER
MOISTURE OFF THE COAST AFTER MIDNIGHT.

MONDAY AND MONDAY NIGHT...THE MAIN COLD FRONT AND ASSOCIATED
DEEPER MOISTURE AXIS SHOULD HAVE SHIFTED OFFSHORE AND INTO THE
ATLANTIC PRIOR TO DAYBREAK MONDAY. GUIDANCE CONTINUES TO HINT AT
SOME RESIDUAL TROUGHING LINGERING IN THE LEE OF THE APPALACHIANS
DUE TO DEEP LAYER CYCLONIC FLOW ASSOCIATED WITH THE UPPER LEVEL
TROUGH. DESPITE THE UNFAVORABLE DEEP LAYER DRYING WHICH WILL TAKE
PLACE BEHIND THE COLD FRONT...THE COMBINATION OF LINGERING
TROUGHING IN THE LEE OF THE APPALACHIANS AND THE RESULTANT
ATLANTIC SEA BREEZE MAY BE JUST ENOUGH OF A CATALYST TO ALLOW FOR
A COUPLE ISOLATED SHOWERS/THUNDERSTORMS TO DEVELOP. GIVEN SOME
LINGERING DYNAMIC FORCING FOR ASCENT WITH THE UPPER LEVEL TROUGH
AND TAIL END OF AN 80+ KNOT H25 JET...ALONG WITH EXTREMELY DRY
MID/UPPER LEVELS...ANY THUNDERSTORMS THAT DO MANAGE TO DEVELOP
COULD BECOME SEVERE. COVERAGE IS NOT EXPECTED TO BE ALL THAT GREAT
HOWEVER...AND WILL LIMIT POPS TO SLIGHT CHANCE FROM COLLETON
COUNTY NORTHWARD DURING THE AFTERNOON/EARLY EVENING. ANY ACTIVITY
WILL END QUICKLY IN THE EVENING...WITH CLEARING SKIES AND RAIN
FREE CONDITIONS THEN EXPECTED OVERNIGHT.

TEMPERATURES ARE EXPECTED TO TOP OUT IN THE LOW TO MID 90S...WITH
LOWS RANGING FROM THE UPPER 60S INLAND TO AROUND 70/LOWER 70S CLOSER
TO THE COAST.

TUESDAY THROUGH WEDNESDAY...MODEL GUIDANCE IS IN GOOD AGREEMENT
SHOWING HIGH PRESSURE AND A DEEP DRY AIRMASS MOVING OVER THE
SOUTHEAST STATES. AS A RESULT...EXPECT RAIN FREE CONDITIONS ACROSS
THE FORECAST AREA. HIGHS WILL TOP OUT GENERALLY IN THE LOWER 90S
AWAY FROM THE COAST...WITH LOWS RANGING FROM THE UPPER 60S INLAND
TO AROUND 70/LOWER 70S CLOSER TO THE COAST.

&&

.LONG TERM /WEDNESDAY NIGHT THROUGH SATURDAY/...
MODEL SOLUTIONS ARE IN GOOD AGREEMENT SHOWING HIGH PRESSURE HOLD IN
PLACE OVER THE REGION THROUGH FRIDAY. A WEAKENING COLD FRONT IS
EXPECTED TO APPROACH FROM THE NORTHWEST THIS UPCOMING WEEKEND...BUT
WILL LIKELY STALL OUT AND DISSIPATE NORTH OF THE REGION. DEEP
MOISTURE WILL TAKE SOME TIME TO FILTER BACK INTO THE REGION...SO
WILL KEEP THE FORECAST FREE FROM RAIN THROUGH THURSDAY NIGHT. THE
LOW LEVEL AIRMASS SHOULD MOISTEN UP BY LATE WEEK AND OVER THE
WEEKEND WITH THE APPROACH OF THE COLD FRONT ALONG WITH SEVERAL DAYS
OF SOUTHEASTERLY AND SOUTHERLY ONSHORE FLOW. AS A RESULT...WILL
CARRY SLIGHT CHANCE/LOW CHANCE POPS FRIDAY THROUGH SUNDAY.
TEMPERATURES ARE EXPECTED TO RUN NEAR OR SLIGHTLY ABOVE CLIMATOLOGY.

&&

.AVIATION /18Z SUNDAY THROUGH FRIDAY/...
WITH AN APPROACHING COLD FRONT...ASSOCIATED SCATTERED TO NUMEROUS
THUNDERSTORM DEVELOPMENT WILL LEAD TO DETERIORATING CONDITIONS AT
BOTH KCHS AND KSAV THROUGHOUT THIS AFTERNOON AND EARLY EVENING.
INITIALIZED KSAV WITH A TEMPO OF TSRA AS ISOLATED CONVECTION HAS
ALREADY DEVELOPED ACROSS PORTIONS OF SOUTHEAST GEORGIA. AS
CONVECTION SPREADS NORTHWARD...INTRODUCED TSRA INTO KCHS TAFS AROUND
20Z. THUNDERSTORMS WILL HAVE THE POTENTIAL FOR PRODUCING STRONG
WINDS AND  HEAVY DOWNPOURS WHICH WILL RESULT IN MVFR OR LOWER
VISIBILITIES. THE COLD FRONT WILL SHIFT OFFSHORE LATE TONIGHT
ALLOWING WINDS TO VEER MORE WESTERLY. AS SKIES CLEAR BEHIND THE
FRONT...COULD SEE SOME PATCHY GROUND FOG DEVELOP EARLY MONDAY
MORNING BUT WILL KEEP CONDITIONS VFR FOR NOW. AFTER SUNRISE...VFR
CONDITIONS WILL PREVAIL THROUGH THE AFTERNOON.

EXTENDED AVIATION OUTLOOK...VFR CONDITIONS ARE EXPECTED.

&&

.MARINE...
THE BIG CONCERN THROUGH TONIGHT WILL BE THE POTENTIAL FOR HAZARDOUS
CONDITIONS WITH STRONG TO SEVERE TSTMS MOVING OFFSHORE THIS
AFTERNOON AND EVENING. STEERING FLOW AHEAD OF A UNSEASONABLY
STRONG UPPER TROUGH IS POISED TO PUSH POCKETS OF ORGANIZED TSTMS
THROUGH THE INTRA-COASTAL AND ACROSS COASTAL WATERS LATER TODAY
AND THIS EVENING. CONVECTIVE WIND GUSTS COULD EXCEED 35 KT AND
RESULT IN LOCALLY HIGHER WAVES AND SEAS.

OTHERWISE...MAINLY SW FLOW AT 15 KT OR LESS WITH SEAS 2 TO 3 FT ON
AVERAGE THROUGH TONIGHT.

MONDAY THROUGH FRIDAY...A WEAK HIGH PRESSURE PATTERN IS EXPECTED
OVER THE WATERS THROUGH THE PERIOD. THIS WILL RESULT IN FAIRLY LIGHT
WINDS...SMALL SEAS...AND CONDITIONS WELL BELOW SMALL CRAFT
THRESHOLDS.

&&

GA...NONE.
