AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHARLESTON SC
530 PM EDT SAT AUG 20 2011

.SYNOPSIS...
ATLANTIC HIGH PRESSURE WILL PREVAIL OVER THE REGION THROUGH SUNDAY.
A COLD FRONT WILL APPROACH FROM THE NORTHWEST MONDAY...THEN STALL
AND EVENTUALLY DISSIPATE OVER OR NEAR THE AREA THROUGH THE MIDDLE OF
NEXT WEEK...AS SURFACE HIGH PRESSURE BUILDS FROM THE ATLANTIC
THROUGH THURSDAY. A TROPICAL CYCLONE MAY IMPACT THE SE LATE IN THE
WEEK.

&&

.NEAR TERM /UNTIL 6 AM SUNDAY MORNING/...
UNTIL AFTER SUNSET...THUNDERSTORMS WILL REMAIN MOST COMMON ALONG
COMPLEX MESOSCALE BOUNDARIES ACROSS INLAND SC COUNTIES. BOUNDARY
INTERACTIONS/CELL MERGERS WILL CONTINUE TO SUPPORT A THREAT FOR
ISOLATED/BRIEF PULSE SEVERE THUNDERSTORMS WITH DAMAGING WIND
GUSTS AND LOCALLY EXCESSIVE RAINFALL. WILL CONTINUE TO ASSESS
POTENTIAL FOR OUTFLOW TO PUSH NEW THUNDERSTORMS TOWARD THE SC
COAST...WHERE POPS REMAIN BELOW 15 PERCENT FOR NOW.

TONIGHT...CONVECTION WILL DISSIPATE AS THE AIRMASS STABILIZES AFTER
SUNSET AND THE REMAINDER OF THE OVERNIGHT SHOULD BE QUIET WITH
JUST SOME SCT DEBRIS CLOUDS MOVING THROUGH. ISOLATED SHOWERS AND
STORMS IN THE COUNTIES COULD STILL DEVELOP ALONG PERSISTENT
BOUNDARIES OVER MIDLANDS/FAR INLAND COUNTIES BUT THAT WILL LARGELY
DEPEND ON WHAT KIND OF CONVECTIVE COVERAGE THERE IS OVERNIGHT
UPSTREAM. OVERNIGHT LOWS AGAIN WILL BE IN THE MID 70S ALONG THE
COAST...LOW 70S INLAND.

&&

.SHORT TERM /6 AM SUNDAY MORNING THROUGH TUESDAY/...
SUNDAY...THE MID AND UPPER LEVEL RIDGE CENTERED IN TEXAS WILL ALIGN
ITSELF EAST AND EAST-SE ACROSS THE NORTHERN GULF OF MEXICO...AS ONE
SHORT WAVE LIFTS INTO THE ATLANTIC PRIOR TO DAYBREAK AND A SECOND
AND STRONGER SHORT WAVE NOW IN THE MID MS VALLEY MOVES IN LATE AND
CONTINUES INTO SUNDAY NIGHT. AT THE SAME TIME...THE SUB TROPICAL
ATLANTIC RIDGE AT THE SURFACE IS SHUNTED SE AHEAD OF THE SHORT WAVE
AND A LEE SIDE TROUGH THAT SAGS CLOSER TO THE AREA BY LATE IN THE
DAY. MOISTURE WILL POOL BETWEEN THE SEA BREEZE AND THE INLAND
TROUGH...WITH SOME INDICATIONS THAT PWATS COULD BE APPROACHING 2.25
OR MORE INCHES. THE FIRST HALF OF THE DAY LOOKS TO BE GENERALLY
RAINFREE...BUT WITH CONVECTIVE TEMPS CLOSE TO 90 WE WILL EXPERIENCE
SOME ISOLATED CONVECTION FORMING ALONG THE SEA BREEZE AND ACROSS
SOME DIFFERENTIAL HEATING BOUNDARIES INLAND BY EARLY AFTERNOON.
COVERAGE WILL THEN INCREASE DURING THE MID/LATE AFTERNOON AND
CONTINUE INTO SUNDAY NIGHT AS THE SHORT WAVE ALOFT MOVES THROUGH.
THERE ARE INDICATIONS THAT SOME ORGANIZED CLUSTERS OF CONVECTION
WILL FORM LATE IN THE DAY AND INTO SUNDAY NIGHT AS A JET MAX ALOFT
MOVES NEARBY...AND UPPER DIVERGENCE OCCURS IN RESPONSE TO THIS AND
THE SHORT WAVE. FOR NOW WE/LL SHOW A SOMEWHAT CONSERVATIVE FORECAST
OF SCATTERED POPS LATE SUNDAY INTO SUNDAY NIGHT...BUT WOULD SUSPECT
THAT POPS WILL NEED TO BE BUMPED UP INTO AT LEAST THE LIKELY RANGE
FOR PARTS OF THE AREA IN LATER FORECASTS. THERMODYNAMICS ARE
FAVORABLE FOR AT LEAST SOME STRONG OR EVEN ISOLATED SEVERE
WEATHER...BUT PROBABILITIES AND COVERAGE ARE TOO LOW TO INCLUDE ION
THE HAZARDOUS WEATHER OUTLOOK AT THIS TIME. DCAPES OF 800-1000 J/KG
SUGGEST THAT STRONG DOWNBURSTS OF WIND ARE POSSIBLE IN SOME STORMS
LATE SUNDAY/SUNDAY NIGHT. WITH 850 MB TEMPS NEAR 18-19C AND LOW
LEVEL THICKNESS VALUES OF 1430-1440 METERS...PLUS A WEST OR NW FLOW
ABOVE THE BOUNDARY LAYER SUPPORTS MAX TEMPS IN THE LOWER TO MIDDLE
90S.

MONDAY...THE SHORT WAVE FROM SUNDAY NIGHT WILL HAVE EXITED OFF INTO
THE ATLANTIC BY DAYBREAK...WHICH LEAVES US WITH NVA DURING MOST OF
THE DAY UNTIL A WEAK SHORT WAVE MOVES IN LATE. THE SUB TROPICAL
ATLANTIC RIDGE WILL BE SHUNTED FURTHER SE AS A COLD FRONT APPROACHES
FROM THE NW...BUT STRUGGLES TO MAKE IT INTO THE AREA UNTIL MONDAY
NIGHT. THERE ARE DEFINITELY SOME FACTORS THAT POINT TOWARD THE
POSSIBILITY OF SOME SEVERE WEATHER. THERE IS THE NOSE OF AN UPPER
JET THAT POKES IN FROM THE OHIO VALLEY...WHILE HEIGHTS ALOFT SLOWLY7
FALL THROUGH THE DAY. LAPSE RATES ARE BETTER THAN ON SUNDAY WITH
EVEN SOME 0-6 KM BULK SHEAR NEAR 30 KT. WITH DRIER MID LEVEL AIR OUR
DCAPES WILL BE AS HIGH AS 1200-1400 J/KG...SO DAMAGING DOWNBURST
WINDS ARE POSSIBLE IN SOME STORMS. BUT GIVEN THE NVA AND THE MAIN
MOISTURE AXIS THAT LOOKS TO PUSH OFFSHORE...WE ARE HESITANT TO ADD
MENTION TO THE HAZARDOUS WEATHER OUTLOOK. BUT KEEP IN MIND THAT SPC
HAS THE AREA IN 5 PERCENT PROBABILITIES OF SEVERE WEATHER...AND THIS
COULD BE ADJUSTED UPWARDS IN THE EARLY MORNING FORECAST ON SUNDAY.
RAIN PROBABILITIES WILL BE IN THE 40 PERCENT RANGE...HIGHEST OVER
EASTERN AREAS WHERE THE SEA BREEZE WILL LIE. COMPRESSIONAL HEATING
AHEAD OF THE FRONT AND 850 MB TEMPS THAT ARE ABOUT A DEGREE HIGHER
SUPPORTS MAX TEMPS SIMILAR TO OR A DEGREE OR SO HIGHER THAN ON
SUNDAY.

TUESDAY...THE COLD FRONT WILL SETTLE INTO THE AREA...BUT BECOMES
DIFFUSE AS HIGH PRESSURE BUILDS FROM OUT OF THE VIRGNIA/S AND PA.
WHILE THERE IS A DECREASE IN MOISTURE AND THERMODYNAMICS...THERE IS
STILL ENOUGH FORCING FROM THE SEA BREEZE AND LOW LEVEL CONVERGENCE
WITHIN A SHALLOW EAST TO NE FLOW TO ALLOW FOR 20-30 POPS. HIGHEST
CHANCES WILL BE SOUTH OF I-16 IN SE GA WHERE BEST MOISTURE AND LIFT
WILL BE FOUND. WITH AN ONSHORE SYNOPTIC FLOW WE WILL KNOCK ABOUT 1-2
DEGREES ON OUR MAX TEMPS...MAINLY REACHING THE 90-95 DEGREE RANGE
AWAY FROM THE BEACHES.

&&

.LONG TERM /TUESDAY NIGHT THROUGH SATURDAY/...
THERE REMAINS A LOT OF UNCERTAINTY IN THE DETAILS OF THE EXTENDED
FORECAST...AS ALL MODELS INDICATE SOME POTENTIAL INFLUENCE FROM A
TROPICAL CYCLONE BY LATE IN THE WEEK. AS THESE DEVELOPMENTS ARE
QUITE FAR OUT INTO THE FORECAST PERIOD...PREFER TO TAKE A
CONSERVATIVE APPROACH AT THIS TIME. BUT ALL PERSONS IN SE SC AND SE
GA SHOULD CONTINUE TO MONITOR THE PROGRESS OF THE TROPICS THROUGH
THE NATIONAL HURRICANE CENTER. SURFACE HIGH PRESSURE WILL
REBUILD BEHIND THE GRADUALLY DISSIPATING FRONT ACROSS THE SOUTHEAST
STATES AND SETTLES BACK OVER THE ATLANTIC BY THE MIDDLE OF THE WEEK.
WE WILL MAINTAIN CHANCE POPS INTO THE WEEKEND TO HINT AT THIS
UNSETTLED PATTERN...WHILE KEEPING TEMPERATURES WITHIN A FEW DEGREES
OF SEASONAL NORMALS.

&&

.AVIATION /21Z SATURDAY THROUGH THURSDAY/...
THUNDERSTORMS APPROACHING KSAV HAD DISSIPATED...WHILE INLAND
THUNDERSTORMS COULD PUSH SOUTH ALONG I-26 AND TOWARD KCHS AROUND
00Z. OTHERWISE...VFR THROUGH THE TAF PERIOD.

EXTENDED AVIATION OUTLOOK...SCATTERED AFTERNOON/EVENING SHOWERS AND
THUNDERSTORMS MAY BRIEFLY REDUCE VSBYS AND/OR CIGS EACH DAY...EXCEPT
FOR MAYBE TUESDAY.

&&

.MARINE...
WINDS WILL GENERALLY BE SOUTH OVERNIGHT...TURNING MORE SOUTHWEST
THROUGH MORNING. BUOY OBSERVATIONS SHOW COMBINED SEAS ARE MAINLY 9
SECOND SWELLS WITH WAVE HEIGHTS OF 2 TO 3 FEET. WITH FORECAST
WINDS IN THE 10 KT RANGE...WILL CONTINUE TO FORECAST SEAS MAINLY 2
TO 3 FEET THROUGH SUNDAY MORNING...PERHAPS AS HIGH AS 4 FT BEYOND
20 NM...WELL BELOW SMALL CRAFT ADVISORY THRESHOLDS.

SUNDAY THROUGH WEDNESDAY...THE COASTAL WATERS WILL LIE ALONG THE
NW EDGE OF THE SUB TROPICAL RIDGE SUNDAY/SUNDAY NIGHT...WITH SOME
MODEST PINCHING OF THE PRESSURE GRADIENT BETWEEN THE RIDGE AND AN
UPSTREAM COLD FRONT. WITH SOME ENHANCEMENT DUE TO SEA BREEZE
CIRCULATIONS SUNDAY AFTERNOON/EVENING AND A 20-25 KT LOW LEVEL JET
SUNDAY NIGHT...WE ARE LOOKING AT SOUTH TO SW WINDS REACHING AS
HIGH AS 15 OR 20 KT. WHILE THERE COULD BE A PERIOD OF SLIGHTLY
HIGHER WINDS ACROSS AMZ350 SUNDAY NIGHT...LATEST THINKING IS THAT
WE/LL REMAIN JUST BELOW ANY SCA CONDITIONS. SEAS DURING THIS TIME
WILL BE THE COMBINATION OF 2-3 FOOT SWELLS AND 2-3 FOOT WIND
WAVES...BUT SIGNIFICANT WAVE HEIGHT WILL GENERALLY HOLD AT 4 FEET
OR LESS.

THE ATLANTIC RIDGE WILL SLOWLY PUSH SE MONDAY AS IT GIVES WAY TO A
COLD FRONT MONDAY NIGHT INTO TUESDAY. SOUTH AND SW WINDS AHEAD OF
THE FRONT WILL SHIFT AROUND TO THE EAST AND NE IN WAKE OF THE
FRONTAL PASSAGE...BUT SPEEDS WILL BE LIMITED TO 15 KT OR LESS. SEAS
WILL REACH NO HIGHER THAN 3 OR 4 FEET.

MARINERS ARE ADVISED THAT SHOULD SOME ORGANIZED CONVECTION DEVELOP
OVER LAND SUNDAY THROUGH MONDAY...THAT WITH A WESTERLY STEERING FLOW
THERE COULD BE SOME STRONG TO SEVERE STORMS THAT IMPACT THE MARINE
AREA. DAMAGING WINDS AND FREQUENT LIGHTNING STRIKES ARE POSSIBLE.

THE COLD FRONT WILL DISSIPATE DURING MID WEEK AS THE ATLANTIC RIDGE
BUILDS BACK INTO THE LOCAL WATERS. THIS KEEPS AN ONSHORE FLOW GOING
AT LESS THAN 15 KT DURING THIS TIME...WITH SEAS 3 FT OR LESS ON
WEDNESDAY...PERHAPS BUILDING A FOOT OR SO ON THURSDAY.

FOR LATE IN THE WEEK OUR ATTENTION SHIFTS TO A POSSIBLE TROPICAL
CYCLONE THAT COULD BE SOMEWHERE TO THE SOUTH OR SW OF THE AREA.
PLEASE REFER TO THE LATEST INFORMATION FROM THE NATIONAL HURRICANE
CENTER.
