AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHARLESTON SC
141 PM EDT MON MAY 11 2015

.SYNOPSIS...
THE REMNANTS OF ANA WILL LIFT NORTHEAST ACROSS EASTERN NORTH CAROLINA
AND ALONG THE MID-ATLANTIC COAST THROUGH TONIGHT. MEANWHILE...A COLD
FRONT WILL APPROACH FROM THE NORTHWEST...MOVING THROUGH THE AREA
TUESDAY NIGHT. THE FRONT WILL LIKELY STALL OR DISSIPATE JUST SOUTH
OF THE AREA MIDWEEK WHILE HIGH PRESSURE BUILDS FROM THE NORTH AND
THEN BECOMES CENTERED OVER THE WESTERN ATLANTIC THIS WEEKEND AND EARLY
NEXT WEEK.

&&

.NEAR TERM /THROUGH TONIGHT/...
A WEAK MID-LEVEL RIDGE CURRENTLY EXTENDS ACROSS CENTRAL AND
EASTERN GA INTO WESTERN SC. A WEAK SHORT WAVE OVER THE SC UPDATE
AS SEEN ON WATER VAPOR IMAGERY WILL DRIFT ESE TODAY...PROVIDING A
FOCUS FOR AFTERNOON CONVECTION ACROSS THE SC MIDLANDS AND PEE DEE
REGION. THE AFOREMENTIONED RIDGE AXIS WILL MAINTAIN A FAIRLY
STRONG CAP ACROSS OUR SOUTHEAST GA COUNTIES...THUS CUMULUS
DEVELOPMENT WILL BE SLOW TO OCCUR. SLIGHTLY DEEPER MOISTURE IN
SOUTHERN SC AND BETTER MID-LEVEL LAPSE RATES AS THE VORT MAX DROPS
INTO THE AREA SHOULD ACCOMMODATE ISOLATED TO SCATTERED TSTMS
DURING THE AFTERNOON. ALTHOUGH THE AFTERNOON SEA BREEZE COULD BE
ENOUGH FORCING TO SQUEEZE OUT AN ISOLATED SHOWER OR STORM ALONG
THE GA COAST...IT WILL PUSH FARTHER INTO SOUTHERN SC AND INTERACT
WITH UPSTREAM CONVECTION. THUS...INITIAL PULSE MODE CONVECTION
COULD TRANSITION TO MULTI-CELLUAR LATE THIS AFTERNOON AS THE SEA
BREEZE INTERACTS WITH EXISTING ACTIVITY. THE HIGH RES GUIDANCE
CONTINUES TO INDICATE THE BEST COVERAGE OF CONVECTION ACROSS OUR
INLAND SC ZONES WHICH IS WHERE WE ARE SHOWING THE HIGHEST POPS. WE
ONLY MADE SOME MINOR TWEAKS TO THE ONGOING FORECAST FOR TODAY.
VERY WARM THICKNESSES WILL SUPPORT HIGHS REACHING THE LOWER 90S IN
MANY AREAS. SEVERE WX POTENTIAL IS LOW THOUGH AN ISOLATED
STRONG/SEVERE STORM IS POSSIBLE.

TONIGHT...MAINLY QUIET WEATHER AFTER EARLY EVENING CONVECTION
DISSIPATES. WARM CONDITIONS ONCE AGAIN WITH LOW IN THE UPPER 60S
TO NEAR 70 MANY AREAS.

&&

.SHORT TERM /TUESDAY THROUGH THURSDAY/...
TUESDAY...A WARM DAY IS EXPECTED AHEAD OF A COLD THAT ENTERS THE
AREA FROM THE NORTHWEST TUESDAY NIGHT INTO EARLY WEDNESDAY. A LACK
OF SIGNIFICANT FORCING SHOULD LIMIT CONVECTIVE COVERAGE DURING THE
DAY ON TUESDAY...BUT THE FORECAST WILL STILL SHOW ISOLATED SHOWERS
AND THUNDERSTORMS ACROSS MUCH OF THE AREA GIVEN STRONG SFC HEATING
ALONG/AHEAD OF AN INLAND MOVING SEABREEZE. TEMPS SHOULD BE THE
WARMEST OF THE WEEK...WITH HIGHS IN THE LOWER 90S AWAY FROM THE
COAST. SHOWERS AND/OR THUNDERSTORMS COULD THEN BECOME SCATTERED IN
COVERAGE TUESDAY NIGHT AS THE COLD FRONT MOVES THROUGH...BUT THE
STRENGTH/INTENSITY OF ACTIVITY WILL LIKELY BE LIMITED DUE TO THE
LOSS OF DAYTIME HEATING. TUESDAY NIGHT LOWS SHOULD RANGE IN THE
MID/UPPER 60S.

WEDNESDAY...THE COLD FRONT WILL SHIFT SOUTH OF THE AREA BEFORE
STALLING/WEAKENING THROUGHOUT THE DAY. HIGH PRESSURE WILL THEN BUILD
BEHIND THE FRONT FROM THE NORTH...RESULTING IN SLIGHTLY COOLER TEMPS
OVER THE REGION. IN GENERAL...HIGH TEMPS SHOULD PEAK IN THE LOWER
80S IN NORTHERN AREAS TO MID/UPPER 80S IN SOUTHEAST GEORGIA. A
SLIGHT CHANCE OF SHOWERS WILL REMAIN IN THE FORECAST...BUT EXPECT
THE GREATEST COVERAGE TO OCCUR OVER LOCATIONS SOUTH OF INTERSTATE 16
IN SOUTHEAST GEORGIA. A THUNDERSTORM OR TWO CAN NOT BE RULED
OUT...MAINLY IN SOUTHERN MOST AREAS ALONG THE ALTAMAHA RIVER.

THURSDAY...SFC HIGH PRESSURE TO OUR NORTH WILL SLIDE TOWARD THE
EASTERN SEABOARD BEFORE SHIFTING OFF THE MID ATLANTIC COAST LATE.
DESPITE STRONG RIDGING ALOFT...TEMPS WILL REMAIN A FEW DEGREES
COOLER THAN THE PREVIOUS DAY AS AN ONSHORE DEVELOPS ALONG THE
SOUTHWESTERN EDGE OF THE HIGH CENTERED TO THE NORTHEAST. MOST AREAS
WILL REMAIN DRY...BUT A FEW SHOWERS AND PERHAPS A THUNDERSTORM COULD
DEVELOP MAINLY OVER AREAS SOUTH OF INTERSTATE 16 IN SOUTHEAST
GEORGIA. AFTERNOON HIGHS SHOULD RANGE IN THE UPPER 70S NEAR THE
COAST TO MID 80S WELL INLAND.

&&

.LONG TERM /THURSDAY NIGHT THROUGH MONDAY/...
SFC HIGH PRESSURE WILL BECOME CENTERED OVER THE WESTERN ATLANTIC BY
THE WEEKEND...RESULTING IN SLIGHTLY COOLER TEMPERATURES INTO LATE
WEEK AS ONSHORE FLOW PERSISTS ALONG THE SOUTHWESTERN EDGE OF THE
RIDGE AXIS. OVERALL HIGH TEMPS SHOULD RANGE IN THE UPPER 70S TO
LOWER 80S ON FRIDAY. BY SATURDAY...THE SFC FLOW WILL BECOME MORE
SOUTH/SOUTHEAST AS THE SFC HIGH BECOMES CENTERED OVER THE ATLANTIC.
THE PATTERN WILL FAVOR CHANCES OF SHOWERS/THUNDERSTORMS AND SLIGHTLY
WARMER TEMPS LATE WEEKEND INTO EARLY NEXT WEEK AS MOISTURE DEEPENS
OVER THE SOUTHEAST AND A SERIES OF MID LVL SHORTWAVES SHIFT OVER THE
AREA. IN GENERAL...HIGH TEMPS SHOULD RANGE IN THE LOW TO MID 80S
LATE WEEKEND AND EARLY NEXT WEEK...WARMEST INLAND.

&&

.AVIATION /17Z MONDAY THROUGH FRIDAY/...
AFTERNOON THUNDERSTORMS HAVE BEGUN TO POP UP...MAINLY AROUND KCHS.
THIS ACTIVITY WILL CONTINUE UNTIL MID-AFTERNOON BEFORE LIFTING
NORTH WITH THE SEA BREEZE LATE. OVERNIGHT WE SHOULD SEE CLEARING
SKIES WITH MODEST SOUTH TO SOUTHWEST WINDS. ANY CONVECTION ON
TUESDAY WILL LIKELY BE AFTER 18Z WHEN A FRONT DROPS TOWARD THE
AREA.

EXTENDED AVIATION OUTLOOK...VFR CONDITIONS ARE EXPECTED TO PREVAIL
OUTSIDE SCATTERED DIURNAL CONVECTION THROUGH LATE WEEK.

&&

.MARINE...
A SW TO S SYNOPTIC FLOW NOW IN PLACE OVER THE WATERS THROUGH
TONIGHT. WINDS WILL MAINLY BE 15 KT OR LESS WITH SEAS 2 TO 4 FT.

TUESDAY THROUGH FRIDAY...A WEAK COLD FRONT WILL THEN APPROACH THE
AREA TUESDAY NIGHT INTO EARLY WEDNESDAY...BEFORE STALLING AND/OR
DISSIPATING SOUTH OF THE WATERS BY THURSDAY. HIGH PRESSURE WILL
BUILD FROM THE NORTH ON THURSDAY BEFORE BECOMING CENTERED OVER THE
WESTERN ATLANTIC LATE WEEK. SOUTHERLY FLOW COULD PEAK TO 15-20 KTS
IN OUTER GEORGIA WATERS AHEAD OF THE FRONT ON TUESDAY...BUT WILL
THEN BECOME MUCH WEAKER LATE WEEK AS HIGH PRESSURE BECOMES
CENTERED JUST NORTH OF THE WATERS. SEAS WILL RANGE BETWEEN 2-4 FT
THROUGH MIDWEEK...BUT WILL GRADUALLY BUILD UP TO 3-5 FT AS
NORTHEAST/EAST FLOW OCCURS OVER COASTAL WATERS LATE WEEK.
