AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHARLESTON SC
336 AM EDT TUE APR 15 2008

...A LATE SEASON FROST AND FREEZE POSSIBLE WELL INLAND TONIGHT...

.SYNOPSIS...
A COLD FRONT WILL PUSH OFFSHORE TODAY. HIGH PRESSURE WILL BUILD
OVER THE REGION TONIGHT AND REMAIN IN PLACE THROUGH FRIDAY.
ANOTHER COLD FRONT WILL MOVE THROUGH THE AREA OVER THE WEEKEND.

&&

.NEAR TERM /THROUGH TODAY/...
THE HIGHLY AMPLIFIED UPPER TROF WILL MOVE EAST TODAY AS UPPER
RIDGING STRENGTHENS ACROSS THE CENTRAL UNITED STATES. SURFACE
OBSERVATIONS OFF THE SOUTH CAROLINA AND GEORGIA COASTS AS WELL AS
INFRARED SATELLITE TRENDS INDICATE CYCLOGENESIS IS ONGOING WELL
EAST OF THE SOUTH CAROLINA AND GEORGIA COASTS THIS MORNING. THE
LOW WILL CONTINUE TO DEEPENING AND DRIFT SLOWLY SOUTHEAST THROUGH
TONIGHT AS THE UPPER LEVEL TROF SHIFTS OFFSHORE.

RADAR SHOWS RESIDUAL SPOTTY LIGHT SHOWERS OVER LAND AREAS. SHOWER
ACTIVITY MAY REFIRE ALONG THE COAST AND THE ADJACENT COASTAL
WATERS AFTER SUNRISE AS INSOLATION COMMENCES AND INTERACTS WITH
THE COLD POOL ALOFT. BEST CHANCES OF ISOLATED TO SCATTERED
SHOWERS WILL BE ALONG THE COAST...WITH ACTIVITY SHIFTING INTO THE
COASTAL WATERS BY LATE MORNING AS ONE FINAL PIECE OF SHORTWAVE
ENERGY CURRENTLY ROUNDING THE BASE OF THE UPPER TROF PIVOTS
OFFSHORE. WILL MAINTAIN 20/30 POPS THROUGH THE MORNING THEN DROP
MENTION OF RAIN BY LATE MORNING FOR ALL LAND AREAS. HIGHS WILL
WILL ONLY TOP OUT IN THE LOWER 60S.

CLOUD DECKS HAVE BROKEN ACROSS MUCH OF SOUTHEAST GEORGIA AND HAVE
LIFTED INTO A THIN ALTOSTRATUS DECK ACROSS SOUTHEAST SOUTH
CAROLINA. THE COLD POOL ASSOCIATED WITH THE UPPER TROF REMAINS IN
PLACE WITH 500MB TEMPERATURES OF -24 TO -26C SO EXPECT THE CLOUDS
WILL FILL BACK IN SHORTLY AFTER SUNRISE AS LAPSE RATES STEEPEN.
THE CLOUD COVER WILL STEADILY DIMINISH FROM NW TO SE THROUGH THE
AFTERNOON AS THE CORE OF THE COLD POOL SHIFTS OFFSHORE AND DRIER
MID-LEVEL AIR ADVECTS IN CYCLONICALLY FROM THE N. EXPECT MOSTLY
CLEAR SKIES TO PREVAIL BY LATE AFTERNOON OR EARLY EVENING ACROSS A
GOOD CHUNK OF THE AREA. IT WILL BE A BREEZY TO WINDY DAY ALONG THE
COAST AS WINDS INCREASE IN RESPONSE TO THE TIGHTENING GRADIENT
BETWEEN THE DEVELOPING LOW PRESSURE WELL OFFSHORE AND HIGH
PRESSURE BUILDING IN FROM THE WEST.

LAKE WINDS...WILL MAINTAIN THE LAKE WIND ADVISORY ON LAKE MOULTRIE
THROUGH TONIGHT AS LAKE WATER TEMPERATURES IN THE UPPER 60S TO
AROUND 70 WILL PROMOTE EFFICIENT MIXING OVER THE OPEN LAKE WATERS.

&&

.SHORT TERM /TONIGHT/...
THE MAIN CONCERN FOR THE SHORT TERM REVOLVES AROUND THE LATE SEASON
FROST/FREEZE POTENTIAL. HIGH PRESSURE WILL BUILD INTO THE REGION
TONIGHT AS THE UPPER TROF SHIFTS OFFSHORE. INLAND AREAS WILL SEE
TEMPERATURES DROP INTO THE LOWER-MID 30S UNDER CLEAR SKIES BUT A
LINGERING GRADIENT BETWEEN THE HIGH AND THE COMPLEX LOW OFFSHORE
RAISES SOME CONCERN OF WHETHER WINDS WILL DIMINISH ENOUGH TO
SUPPORT SCATTERED FROST FORMATION. LOWS CLOSER THE COAST WILL
RANGE FROM THE UPPER 30S TO THE MID 40S AT THE BEACHES SO THERE
ARE NO FROST CONCERNS THERE.

ATTM WE BELIEVE LOCATIONS ALONG AND WEST OF A REIDSVILLE-STATESBORO-
HAMPTON LINE WILL HAVE THE GREATEST CHANCE OF SEEING WINDS DIMINISH
ENOUGH FOR FROST SINCE THIS AREA WILL BE CLOSEST TO THE CENTER OF
THE SURFACE HIGH AND THE FARTHEST DISPLACED FROM THE COASTAL
PRESSURE GRADIENT. WILL ISSUE A FROST ADVISORY FOR HAMPTON/BULLOCH/
EVANS/CANDLER/TATTNALL WITH A FREEZE WATCH FOR THE NORMALLY COLDER
JENKINS/SCREVEN/ALLENDALE CORRIDOR WHERE THE PROBABILITIES OF A
LIGHT FREEZE ARE THE GREATEST. WILL LIKELY SEE SOME PATCHY FROST
EAST OF THIS AREA INCLUDING LUDOWICI-SPRINGFIELD-WALTERBORO AND
MONCKS CORNER BUT OUR WIND CONCERNS YIELD TOO LOW OF A CONFIDENCE
TO JUSTIFY A FROST ADVISORY ATTM. SHOULD THE LOW END AND ASSOCIATED
GRADIENT END UP FARTHER OFFSHORE THEN THE RISK FOR SCATTERED FROST
WILL INCREASE. THE DAY SHIFT WILL BE IN A BETTER POSITION TO MAKE
THAT CALL.

&&

.LONG TERM /WEDNESDAY THROUGH MONDAY/...
DEEP LAYERED RIDGING WILL SLOWLY SHIFT EASTWARD ACROSS THE AREA
WED-FRI...ALLOWING FOR CLEAR SKIES AND A JUMP IN TEMPERATURES BACK
TO NEAR NORMAL LEVELS BY THU-FRI.

THE NEXT SYSTEM OF CONSEQUENCE LOOKS TO MOVE THROUGH THE AREA OVER
THE WEEKEND...BUT THE DETAILS OF THIS SYSTEM ARE HIGHLY QUESTIONABLE
DUE TO MODEL INCONSISTENCIES...BOTH AMONG THE DIFFERENT MODELS AND
WITHIN MODEL RUN-TO-RUN DIFFERENCES. ATTM...THE GEM/ECMWF/UKMET ARE
IN ONE SCHOOL OF THOUGHT WHILE THE GFS IS THE OUTLIER IN MORE THAN
ONE RESPECT SO WILL DEFER TO THE OTHER 3 MODELS WHICH AFTER GOOD
DISCUSSION WITH HPC IS ALSO THEIR THINKING.

A POTENT UPR LEVEL TROF MAKING ITS WAY ONTO THE WEST COAST TDA WILL
GRADUALLY TRAVERSE THE LOWER 48 THROUGH THE WEEK AND TAKE A TRACK
OVER THE SOUTHERN PLAINS AND GULF COAST STATES FRI-SAT...WHILE ITS
SURFACE REFLECTION DRAGS A COLD FRONT THROUGH THE SAME AREAS. THIS
FRONT LOOKS TO PUSH THROUGH THE AREA SAT AND BE OFFSHORE BY SUN MRNG
WHILE THE ASSOCIATED UPPER LEVEL LOW REACHES THE COAST BY SUN
EVENING. WITH THIS SCENARIO...HAVE ADJUSTED POPS TO SHOW THE BEST
CHC FOR PRECIP DURING THE DAY ON SAT ALBEIT ONLY GOING AS HIGH AS 30
DUE TO THE MODEL UNCERTAINTY. THIS IS SURROUNDED BY SLGT CHC POPS
INLAND FOR FRI NIGHT AND SLGT CHC POPS FOR ALL AREAS ON SAT NIGHT.
HAVE OPTED TO KEEP THUNDER MENTION OUT OF THE FCST DUE TO THE
AFOREMENTIONED MODEL DIFFICULTIES...BUT IF PRESSED THEN THE BEST
CHCS FOR THUNDER WOULD SEEM TO BE SAT AFTN DUE TO THE TIMING OF THE
FRONT AND SUPPOSED HEATING/INSTABILITY AHEAD OF THE FRONT.

HIGH PRESSURE THEN LOOKS TO BUILD BACK INTO THE AREA BEHIND THE
FRONT FOR SUN-MON...HENCE A DRY FCST. NOT MUCH COLD AIR ADVECTION IS
AVAILABLE BEHIND THE FRONT SO HAVE NUDGED TEMPS BACK TO SLIGHTLY
BELOW NORMAL LEVELS FOR THE START OF NEXT WEEK.

&&

.AVIATION /06Z TUESDAY THROUGH SATURDAY/...
VFR CONDITIONS WILL PREVAIL THROUGHOUT THE 15/06Z TAFS. AS AN
UPPER LEVEL COLD POOL LOW PUSHES OFFSHORE...MID AND UPR LVL CLOUDS
AROUND THE BASE OF THE LOW WILL REMAIN IN PLACE THROUGH AT LEAST
THE FIRST HALF OF THE DAY. AM NOT EXPECTING CIGS TO DROP TO MVFR
LEVELS...BUT WILL KEEP 8-12 KFT CIGS IN PLACE THROUGH MOST OF THE
DAY ALONG WITH FEW/SCT MIDLVL CLOUDS. SKIES WILL GRADUALLY CLEAR
OUT THIS EVNG THROUGH OVERNIGHT TONIGHT AS THE UPPER LOW MOVES
WELL OFFSHORE AND HIGH PRESSURE BUILDS IN. THE ONLY OTHER CONCERN
WILL BE STRONG/GUSTY SURFACE WIND SPEEDS WITHIN A TIGHT PRESSURE
GRADIENT DUE TO A COLD FRONT MOVING OFFSHORE UNDERNEATH THE
AFOREMENTIONED UPPER LEVEL LOW. AFTER DAYBREAK...WINDS WILL SHIFT
TO NORTHERLY AND SUSTAINED WIND SPEEDS WILL INCREASE TO AROUND 20
KT WITH GUSTS APPROACHING 30 KT. BY SUNSET...WINDS WILL SETTLE
BACK DOWN TO AROUND 10-12 KT.

EXTENDED AVIATION OUTLOOK...VFR CONDITIONS TO PREVAIL THROUGH FRI
NIGHT. A COLD FRONT MAY APPROACH THE AREA SATURDAY AND BRING MVFR
CIGS/VSBYS WITH SCATTERED SHOWERS.

&&

.MARINE...
ONGOING SMALL CRAFT ADVISORIES AND GALE WARNINGS LOOK ON TRACK.
THE GALE WATCH FOR THE WATERS FROM THE SOUTH SANTEE RIVER TO
EDISTO BEACH OUT 20 NM WILL BE UPGRADED TO A GALE WARNING WITH
THIS FORECAST CYCLE.

SURFACE OBSERVATIONS INDICATE LOW PRESSURE IS DEVELOPING WELL EAST
OF THE SOUTH CARLINA AND GEORGIA COASTS THIS MORNING. THE LOW WILL
CONTINUE TO DEEPEN THROUGH TONIGHT AS THE POTENT UPPER TROF SHIFTS
OFFSHORE. THE RESULTING GRADIENT BETWEEN THE LOW AND BUILDING HIGH
PRESSURE FROM THE WEST WILL RESULT IN VERY HAZARDOUS MARINE
CONDITIONS THROUGH TONIGHT WITH FREQUENT GUSTS TO GALE FORCE
LIKELY OCCURRING OVER THE CHARLESTON COUNTY COASTAL WATERS AND
OVER THE GEORGIA OFFSHORE WATERS. ACROSS THE CHARLESTON HARBOR
AND THE WATERS SOUTH OF EDISTO BEACH TO THE ALTAMAHA SOUND...WINDS
WILL BE A BIT LESS BUT SOLIDLY WITHIN SMALL CRAFT ADVISORY THRESHOLDS.
OFFSHORE TRAJECTORIES WILL LIMIT SEA GROWTH NEAR THE COAST...BUT
WILL BUILD RAPIDLY BEYOND 20 NM. SEAS WILL RANGE FROM THE 2-3 FT
NEAR THE IMMEDIATE COAST TO 5-7 FT 20 NM OUT AND AS HIGHS AS 9-12
FT OVER THE GEORGIA OFFSHORE WATERS.

RATHER TRANQUIL CONDITIONS WILL PREVAIL FOR WED THROUGH FRI AS HIGH
PRESSURE MOVES OVER THE WATERS...ALLOWING FOR WINDS AND WAVES TO
GRADUALLY SUBSIDE. GUSTS TO GALE FORCE MAY STILL BE EXPERIENCED OVER
THE OUTER GA WATERS WEDNESDAY MORNING WHILE ALL REMAINING MARINE
ZONES WILL STILL HAVE LINGERING SCA WIND SPEEDS. HOWEVER...BY WED
EVE ALL NEARSHORE HEADLINES SHOULD BE DROPPED WHILE THE OUTER GA
WATERS WILL STILL HAVE SCA WAVE HEIGHTS THROUGH THU AFTN AND
POSSIBLY THU EVE.

CONDITIONS THEN LOOK TO REMAIN BELOW SCA LEVELS THROUGH FRI NIGHT.
ANOTHER COLD FRONT WILL APPROACH FROM THE W ON SATURDAY AND A
PINCHED GRADIENT AHEAD OF THIS FRONT MAY BRING SCA CONDITIONS BACK
TO THE COASTAL WATERS. HOWEVER...WITH A GREAT DEAL OF UNCERTAINTY IN
THE MODELS WITH THIS UPCOMING SYSTEM...CONFIDENCE IS NOT HIGH ENOUGH
TO PINPOINT IF/WHERE SCA CONDITIONS MAY BE EXPERIENCED SO WILL KEEP
WAVES AOB 5 FT AND WINDS NO HIGHER THAN 15-20 KT.

&&

.FIRE WEATHER...
CRITICAL WINDS ARE EXPECTED ACROSS THE EASTERN ZONES TODAY WHERE
THE GRADIENT WILL BE THE TIGHTEST. RELATIVE HUMIDITIES WILL BOTTOM
OUT IN THE 30-35 PCNT RANGE. ALTHOUGH FUELS ARE DRY...CONDITIONS
DO NOT SUPPORT RED FLAG CONDITIONS ATTM. SINCE HUMIDITIES ARE ONLY
EXPECTED TO DROP INTO THE 30-35 PCNT RANGE...THE FIRE DANGER
STATEMENT THAT WAS ISSUED YESTERDAY WILL NOT BE REISSUED.

&&

.CLIMATE...
WITH SUCH COLD AIR MOVING OVER THE AREA THROUGH TUE NIGHT...SEVERAL
LOW MIN AND LOW MAX TEMPS COULD BE THREATENED. HERE IS A LISTING OF
THE UPCOMING RECORDS THAT COULD BE IN JEOPARDY...

RECORD LOW MAX TEMPS FOR APRIL 15...
