AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHARLESTON SC
1232 PM EDT SUN JUN 26 2011

.SYNOPSIS...
THE REGION WILL REMAIN BETWEEN ATLANTIC HIGH PRESSURE AND AN
INLAND TROUGH OF LOW PRESSURE INTO MID WEEK BEFORE A COLD FRONT
APPROACHES FROM THE NORTHWEST.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
NO MAJOR CHANGES WITH THE 1 PM UPDATE. TSTMS CONTINUE TO FIRE
ALONG A SOUTHWARD MOVING OUTFLOW BOUNDARY ACROSS NORTHERN GEORGIA.
CURRENT MESOSCALE TRENDS SUGGEST WE MAY NEED TO INCREASE POPS
ACROSS INTERIOR SOUTHEAST GEORGIA WITH THE LATE AFTERNOON UPDATE.

H8 TEMPERATURES ARE FORECAST TO RISE TO 19-21C BY LATE AFTERNOON
WHICH COUPLED WITH MOSTLY SUNNY SKIES WILL ALLOW HIGHS TO SOAR
WELL INTO THE 90S WITH MANY LOCATIONS ACROSS THE SOUTHWEST ZONES
LIKELY TOPPING OUT 100-101. THIS INCLUDES LOCATIONS SUCH AS
STATESBORO...SYLVANIA...METTER...REIDSVILLE...CLAXTON AND LUDOWICI.
DEWPOINTS WILL MIX OUT INTO THE 60S AND POSSIBLE UPPER 50S WHICH
WILL KEEP HEAT INDICES IN CHECK. THE ONLY EXCEPTION WILL BE ACROSS
THE COASTAL COUNTIES WHERE HIGH RESOLUTION MODEL DATA SHOW DEWPOINTS
SURGING INTO THE MID-UPPER 70S WITH THE SEA BREEZE. THIS MAY RESULT
IN HEAT INDICES BRIEFLY RISING 104-106 FOR ONE MAYBE TWO HOURS...BUT
THIS SMALL TEMPORAL WINDOW DOES NOT JUSTIFY THE ISSUANCE OF HEAT
ADVISORY ATTM. WE WILL OBVIOUSLY MONITOR CONDITIONS THROUGH THE DAY
AND MAKE NECESSARY CHANGES AS NEEDED.

RISING HEIGHTS ALOFT COUPLED WITH DEWPOINTS MIXING OUT INTO THE
LOWER 60S DOES NOT BODE WELL FOR SIGNIFICANT LATE AFTERNOON TSTM
DEVELOPMENT. WEAK SHORTWAVE ENERGY PASSING OVER THE MIDLANDS AND
CSRA THIS AFTERNOON COULD PROVIDE JUST ENOUGH FORCING TO OVERCOME
THIS LACK OF SIGNIFICANT MOISTURE AND SURFACE BASED INSTABILITY
TO YIELD ISOLATED TSTMS. SIMILARLY...AN ISOLATED TSTM OR TWO COULD
POP ALONG THE SEA BREEZE WHERE LOW-LEVEL MOISTURE POOLING WILL
HELP SPIKE SBCAPES TO NEAR 3000 J/KG. THIS SCENARIO IS WELL
SUPPORTED BY THE LATEST SET OF HIGHER RESOLUTION GUIDANCE. WILL GO
WITH SLIGHT CHANCE POPS ALONG AND AHEAD OF THE SEA BREEZE TO COVER
THIS POSSIBILITY.

WE ARE CAREFULLY WATCHING MESOSCALE TRENDS ASSOCIATED WITH THE MCS
OVER TENNESSEE. VISIBLE SATELLITE IMAGES SHOW A WELL DEFINED
OUTFLOW BOUNDARY SINKING SOUTH AND APPROACHING NORTHERN MISSISSIPPI...
ALABAMA...GEORGIA AND THE BLUE RIDGE MOUNTAINS OF SOUTHWEST NORTH
CAROLINA. THIS BOUNDARY WILL LIKELY BE A FOCUS FOR ADDITIONAL
TSTMS LATER THIS AFTERNOON FARTHER UPSTREAM. THE FLOW AROUND THE
LARGE ANTICYCLONE CENTERED OVER TEXAS MAY ALLOW SOME OF THIS
ACTIVITY TO MOVE INTO THE AREA THIS EVENING...ESPECIALLY SOUTHEAST
GEORGIA SO THIS IS SOMETHING WE WILL HAVE TO CAREFULLY
WATCH...ESPECIALLY AS IT MAY EVENTUALLY LINK UP WITH THE INLAND
MOVING SEA BREEZE.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH WEDNESDAY/...
TONIGHT...ISOLATED SHOWERS/THUNDERSTORMS COULD GET A BOOST AS
OUTFLOW FROM AN APPROACHING MCS MOVING SOUTHEAST THROUGH NORTH
GEORGIA POTENTIALLY COLLIDES WITH THE SEA BREEZE ACROSS INTERIOR
PORTIONS OF OUR FORECAST AREA. KEPT POPS FAIRLY LOW FOR NOW GIVEN
THE USUAL UNCERTAINTY WITH POOR MODEL BEHAVIOR OF SUCH FEATURES
BUT COVERAGE COULD BE DECENT AS SOME OF THE MESOSCALE MODELS
SUGGEST. DEPENDING ON THE ORGANIZATION OF UPSTREAM
CONVECTION...SOME SEVERE STORMS ARE POSSIBLE...BUT WILL LET LATER
SHIFTS DIAGNOSE THIS FURTHER. LOWS MAINLY IN THE LOWER TO MID 70S.

MONDAY THROUGH WEDNESDAY...NO SIGNIFICANT CHANGES HAVE BEEN MADE
DURING THE SHORT TERM FORECAST. A WEAK NORTHWEST FLOW REGIME WILL
CONTINUE OVER THE SOUTHEAST AS SIGNIFICANT MID/UPPER LVL RIDGING
OCCURS OVER THE CENTRAL UNITED STATES AND MODEST RIDGING REMAINS
OVER THE WESTERN ATLANTIC. 1000-850MB THICKNESS VALUES CONTINUE TO
SUPPORT HIGH TEMPS IN THE LOW/MID 90S THROUGH WEDNESDAY WITH
OVERNIGHT LOWS IN THE LOW 70S AND MID/UPPER 70S ALONG THE
IMMEDIATE SC AND GA COASTLINE.

IN GENERAL...A CHANCE OF SHOWERS AND THUNDERSTORMS WILL BE POSSIBLE
EACH AFTERNOON WITH COVERAGE INCREASING THROUGH WEDNESDAY.
CONVECTION WILL LIKELY DEVELOP NEAR/WITHIN A LEE SIDE TROUGH OVER
THE MIDLANDS BEFORE MAKING WAY TO THE LOW COUNTRY AS WEAK H5
SHORTWAVES ROUND THE NORTHEASTERN PERIPHERY OF THE RIDGE POSITIONED
TO OUR WEST. ACTIVITY MAY BE SOMEWHAT ENHANCED EACH AFTERNOON AND
EVENING WITH AN INLAND MOVING SEABREEZE AND ANY CONVECTIVE OUTFLOW
BOUNDARIES. AT THIS TIME...THE BEST CHANCE OF ACTIVITY LOOKS TO BE
TUESDAY AFTERNOON AND WEDNESDAY AS POOLING OF MOISTURE AND SBCAPES
APPROACH 3000 J/KG ALONG/AHEAD OF A WEAK SFC TROUGH THAT MAKES WAY
THROUGH THE SOUTHEAST BY LATE WEDNESDAY. HAVE INCREASED POPS
SLIGHTLY TUESDAY AFTERNOON AND WEDNESDAY IN RESPONSE TO THIS SFC
FEATURE.

&&

.LONG TERM /WEDNESDAY NIGHT THROUGH SATURDAY/...
A WEAKENING SFC TROUGH MAY BE LINGERING JUST OFFSHORE WITH AMPLE
MOISTURE STILL OVER PORTIONS OF THE FORECAST AREA...ESPECIALLY ALONG
THE COAST. ISOLATED TO SCATTERED SHOWERS AND THUNDERSTORMS WILL
CONTINUE WEDNESDAY NIGHT THROUGH THURSDAY EVENING BEFORE SFC HIGH
PRESSURE SETTLES IN OVER THE SOUTHEAST. CONDITIONS APPEAR TO BE
SOMEWHAT DRIER EARLY THIS WEEKEND BEFORE WEAK ONSHORE FLOW RETURNS
SUNDAY. HOWEVER...CAN NOT RULE OUT ISOLATED SHOWER/THUNDERSTORM
POSSIBILITY THROUGH THE WEEKEND. OVERALL...HIGH TEMPS WILL BE AROUND
90 DEGREES THURSDAY AND FRIDAY BEFORE A SLIGHT WARMING TREND RETURNS
LATE THIS WEEKEND.

&&

.AVIATION /18Z SUNDAY THROUGH FRIDAY/...
NO CONCERNS. TSTMS CURRENT ORGANIZING OVER NORTHERN GEORGIA MAY
TRY AND SNEAK INTO PORTIONS OF SOUTHEAST GEORGIA THIS EVENING.
THIS MAY POSE A RISK FOR TSTMS AT KSAV. WILL HAVE TO WATCH THIS
CAREFULLY BUT WILL LEAVE TSTMS OUT OF THE 18Z TAFS FOR NOW. TSTMS
ARE NOT A CONCERN ATTM FOR KCHS.

EXTENDED AVIATION OUTLOOK...MVFR/IFR CONDITIONS POSSIBLE EACH
AFTERNOON/EVENING WITH SHOWER/THUNDERSTORM ACTIVITY...ESPECIALLY
TUE AND WED.

&&

.MARINE...
TODAY AND TONIGHT...NO SIGNIFICANT CONCERNS. S/SW WINDS OF 15 KT
OR LESS AND SEAS 2 TO 4 FT OR LESS.

MONDAY THROUGH FRIDAY...WINDS AND SEAS ARE EXPECTED TO REMAIN
BELOW SCA CRITERIA MONDAY AND TUESDAY WITH WITH ATLANTIC HIGH
PRESSURE DOMINATING THE WATERS. HIGHEST WINDS WILL REMAIN ALONG
DAILY SEABREEZE CIRCULATIONS NEAR THE COAST. WINDS AND SEAS WILL
APPROACH SCA CRITERIA TUESDAY NIGHT THROUGH LATE WEDNESDAY MORNING
AS A SFC TROUGH PINCHES THE GRADIENT OVER COASTAL WATERS. WINDS
WILL APPROACH 20 TO 25 KTS...MAINLY FOR WATERS BEYOND 20 NM FROM
THE COAST...BUT NORTHERN SC WATERS MAY ALSO SEE SCA CONDITIONS
BRIEFLY. SEAS WILL ALSO BUILD UP TO 5 TO 6 FEET FOR WATERS BEYOND
20 NM FROM THE COAST. CONDITIONS WILL THEN IMPROVE LATE WEEK.

&&

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