AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHARLESTON SC
742 AM EDT FRI MAY 9 2008
.SYNOPSIS...
A TROUGH OF LOW PRESSURE WILL MOVE THROUGH THE REGION TODAY. A
BACKDOOR COLD FRONT WILL MOVE SOUTHWARD THROUGH THE AREA SATURDAY
NIGHT...THEN LIFT BACK NORTHWARD AS A WARM FRONT SUNDAY. A STRONG
COLD FRONT WILL THEN PUSH THROUGH THE REGION SUNDAY NIGHT. HIGH
PRESSURE WILL THEN RETURN THROUGH MID WEEK.
&&
.NEAR TERM /UNTIL 6 PM THIS EVENING/...
CURRENTLY AT THE SURFACE...A TROUGH OF LOW PRESSURE EXTENDS FROM
CENTRAL VIRGINIA AND NORTH CAROLINA...SOUTHWESTWARD INTO THE UPSTATE
OF SOUTH CAROLINA AND INTO CENTRAL GEORGIA. RADAR IMAGERY INDICATES
SCATTERED SHOWERS AND A FEW EMBEDDED THUNDERSTORMS ALONG THE TROUGH
OF LOW PRESSURE...WITH SATELLITE IMAGERY SHOWING SCATTERED TO BROKEN
CLOUD COVER ACROSS THE AREA. MAIN NEAR TERM CONCERN FOR TODAY
REVOLVE AROUND POPS AND SEVERE THUNDERSTORM POTENTIAL THIS
AFTERNOON.
TODAY...
THE TROUGH OF LOW PRESSURE WILL MOVE THROUGH MUCH OF THE FORECAST
AREA THIS MORNING...THEN DISSIPATE NEAR THE COAST THIS AFTERNOON.
WILL CARRY CHANCE POPS FOR SHOWERS/THUNDERSTORMS ACROSS THE ENTIRE
FORECAST AREA...WITH HIGHEST PROBABILITIES THIS MORNING. GIVEN
STRONG SOUTHWESTERLY STEERING FLOW...DON/T ANTICIPATE THE SEA BREEZE
MAKING MUCH INROADS ACROSS THE FORECAST AREA TODAY...WITH ONLY
CHARLESTON AND BERKELEY COUNTIES POSSIBLY SEEING A BIT OF A
RESULTANT THIS AFTERNOON. WITH LACK OF ANY OTHER LIFTING MECHANISM
BESIDES THE RESULTANT SEA BREEZE...EXPECT THE ONLY LOCATIONS THAT
MAY SEE AN ISOLATED SHOWER OR THUNDERSTORM THIS AFTERNOON WOULD BE
ACROSS CHARLESTON OR BERKELEY COUNTIES. ADJUSTING MODEL SOUNDINGS
YIELDS CAPE VALUES AROUND 2500 J/KG AND LI/S OF -6 TO -7.
FURTHERMORE...GIVEN MID-LEVEL LAPSE RATES OF 7 TO 7.5 C/KM...WBZ
HEIGHTS OF 9.8 KFT AND PLENTY OF MID-LEVEL DRY AIR...ANY
THUNDERSTORMS THAT DUE DEVELOP WILL HAVE THE POTENTIAL OF BECOMING
SEVERE. WEST-SOUTHWEST STEERING FLOW SHOULD LIMIT COVERAGE TO SLIGHT
CHANCE AT BEST...BUT WILL NEED TO CONTINUE TO MONITOR THE SITUATION
CLOSELY GIVEN THE IMPRESSIVE INSTABILITY PARAMETERS THAT WILL BE IN
PLACE. HIGH TEMPERATURES ARE EXPECTED TO TOP OUT AROUND 90 TO THE
LOWER 90S AWAY FROM THE COAST.
LAKE WINDS...LATEST OBSERVATIONS FROM PINEVILLE INDICATE SUSTAINED
WINDS OF AROUND 20 KNOTS...SO WILL CONTINUE THE LAKE WIND ADVISORY
THROUGH MID-MORNING. WINDS SHOULD SUBSIDE SOMEWHAT BY LATE MORNING
AS STRONGEST LOW LEVEL WINDS SHIFT EASTWARD AND AWAY FROM THE AREA.
&&
.SHORT TERM /6 PM THIS EVENING THROUGH 6 AM SATURDAY/...
A FRONTAL BOUNDARY TO THE NORTH OF THE REGION WILL KEEP A DRY
WEST-SOUTHWEST FLOW IN PLACE ACROSS THE FORECAST AREA. EXPECT MOSTLY
CLEAR SKIES WILL GIVE WAY TO PARTLY CLOUDY CONDITIONS OVERNIGHT AS
DEBRIS CLOUDS FROM UPSTREAM CONVECTION BEGIN TO SPILL INTO THE
REGION. OVERNIGHT LOWS ARE EXPECTED TO BOTTOM OUT GENERALLY IN THE
MID TO UPPER 60S.
&&
.LONG TERM /SATURDAY THROUGH THURSDAY/...
OVERALL WE THINK SAT WILL BE MAINLY DRY WITH A FAIRLY DEEP WESTERLY
FLOW KEEPING CONDITIONS QUITE WARM AS WELL. A COUPLE OF THINGS TO
WATCH FOR IS A SHORT WAVE MOVING OUT OF N GEORGIA AND THE SOUTHERN
MIDLANDS AROUND DAYBREAK THAT MAY PUSH ISOLD CONVECTION INTO THE
CSRA AND POSSIBLE SOME OF OUR INLAND ZONES. THIS ACTIVITY SHOULD
DIMINISH BY MID TO LATE MORNING. LINGERING MID LEVEL MOISTURE
AND DECENT INSTABILITY COULD BE ENOUGH TO SPARK SOME SEA BREEZE OR
BOUNDARY RELATED STORMS IN THE AFTERNOON.
THINGS REALLY BECOME INTERESTING ON SAT NIGHT AS LOW LEVEL
FORCING STRENGTHENS AND A DEVELOPING WARM FRONT TAKES SHAPE
SOMEWHERE NEAR THE SAVANNAH RIVER BY MID MORNING. THAT BOUNDARY
WILL NEED TO BE MONITORED CLOSELY AS STRONG UPPER LEVEL DYNAMICS
LIFT THOUGH THE REGION ON SUNDAY. VERY POTENT THETA-E ADVECTION
AND INSTABILITY WILL LIKELY DRIVE AN AREA OF STRONG TO SEVERE
CONVECTION QUICKLY THROUGH THE PARTS OF N GEORGIA AND THE CAROLINAS
DURING THE DAY. AGREE WITH SPC THAT THIS POTENTIAL EVENT HAS
MARKINGS FOR A POSSIBLY SIGNIFICANT EVENT SOMEWHERE IN THE SE
STATES. WE INCREASED POPS LATE SAT NIGHT TO 30-40 PCNT THEN
LIKELY POPS OVER NW HALF OF THE CWFA ON SUNDAY. GUSTY SW WINDS
ARE ALSO A GOOD BET SUNDAY BEHIND THE LIFTING FRONT FRONT.
SHOWERS/TSTMS WILL END SUN NIGHT FOLLOWED BY ADVECTION OF COOLER
AND DRIER AIR. MON SHOULD BE BREEZY TO WINDY WITH PLENTY OF
SUNSHINE IN DOWNSLOPE REGIME. MUCH OF NEXT WEEK LOOKS DRY WITH
ANOTHER SYSTEM APPROACHING SOMETIME AFTER MID WEEK.
&&
.AVIATION /12Z FRIDAY THROUGH TUESDAY/...
A LINE OF THUNDERSTORMS IS HEADING TOWARD THE TERMINALS THIS
MORNING...AND HAVE INCLUDED TEMPO GROUPS AT BOTH TERMS MENTIONING
MVFR CIGS...IFR VSBY/S AND GUSTY WINDS BETWEEN 12Z AND 15Z TO
ACCOUNT FOR THE LINE OF STORMS MOVING THROUGH. AFTER 16Z VFR
CONDITIONS ARE EXPECTED...AS WESTERLY FLOW AND LACK OF ANY SURFACE
LIFTING MECHANISM SHOULD KEEP ANY SHOWERS AND THUNDERSTORMS FROM
DEVELOPING.
EXTENDED AVIATION OUTLOOK...IFR CIGS AND VSBYS MAY DEVELOP
SATURDAY NIGHT INTO EARLY SUNDAY IN ASSOCIATION WITH A DEVELOPING
WARM FRONT. THIS WARM FRONT WILL LEAD TO INCREASING CHANCES OF
SHOWERS AND THUNDERSTORMS AS IT LIFTS NORTHWARD ON SUNDAY. MVFR OR
LOWER CIGS/VSBYS ARE POSSIBLE SUNDAY AFTERNOON IN SHOWERS AND
THUNDERSTORMS...WITH GUSTY SURFACE WINDS. CONDITIONS ARE EXPECTED
TO RETURN TO VFR LEVELS SUNDAY THROUGH TUESDAY.
&&
.MARINE...
A TROUGH OF LOW PRESSURE WILL APPROACH THE WATERS THIS
MORNING...THEN DISSIPATED NEAR THE SOUTH CAROLINA AND GEORGIA COAST
THIS AFTERNOON. STRONG SOUTHERLY TO SOUTHWESTERLY WINDS WILL
CONTINUE IN ADVANCE OF AN APPROACHING TROUGH OF LOW PRESSURE TODAY.
WILL NEED TO CARRY SMALL CRAFT ADVISORIES THROUGH MID-MORNING ACROSS
ALL WATERS FOR WINDS/SEAS OR A COMBINATION OF THE TWO. SMALL CRAFT
CONDITIONS ARE EXPECTED TO LINGER THROUGH THE AFTERNOON ACROSS THE
NORTHERN LEG OF THE SOUTH CAROLINA NEARSHORE AS WELL AS CHARLESTON
HARBOR. ACROSS THE OUTER GEORGIA WATERS...SMALL CRAFT CONDITIONS ARE
EXPECTED TO CONTINUE THROUGH TONIGHT.
A SURFACE TROUGH WILL LINGER ACROSS THE CAROLINAS ON SAT WITH
A 10 TO 15 KT OFFSHORE FLOW BACKING SW WITH EFFECTS OF DIURNAL
HEATING IN THE AFTERNOON AND SEAS MOSTLY 2-3 FT. MARINE FORECAST
FOR SAT NIGHT AND SUN IS SUPREMELY DIFFICULT WITH THE MODELS
INDICATING THE FRONT WILL BACKDOOR S INTO OUR S CAROLINA WATERS
SPARKING A POTENTIAL NE SURGE OFF OF CHARLESTON COUNTY AND SW
FLOW LIKELY JETTING OFF OUR SRN GEORGIA WATERS. THE FRONT IS
EXPECTED TO LIFT N ON SUN IN RESPONSE TO THE APPROACH OF STRONG
ATMOSPHERIC DYNAMICS. A 40-50 KT H85 JET ON SUNDAY SUGGESTS THAT
SCA CONDITIONS WILL OVERSPREAD THE WATERS IN SSW FLOW. SEAS WILL
BUILD TO 4-7 FT...POSSIBLY HIGHER WELL OFFSHORE.
ADVISORIES WILL LIKELY CONTINUE INTO MON AS COOLER AND DRIER AIR
ADVECTS IN THE REGION. TAMER CONDITIONS SHOULD DEVELOP BY MIDWEEK.
