AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHARLESTON SC
222 AM EDT THU APR 5 2012

.SYNOPSIS...
A BACKDOOR COLD FRONT APPROACHES FROM THE NORTH TODAY. THE FRONT
WILL EVENTUALLY MOVE THROUGH THE AREA TONIGHT AND EARLY
FRIDAY...AS A WAVE OF LOW PRESSURE DEVELOPS ON THE FRONT AND
DEEPENS OVER THE GULF STREAM. COOLER HIGH PRESSURE WILL THEN BUILD
BEHIND THE FRONT FOR THE EASTER WEEKEND. A SECONDARY COLD FRONT
WILL MOVE THROUGH SUNDAY NIGHT...WITH YET ANOTHER COLD FRONT TO
CROSS THE AREA TUESDAY.

&&

.NEAR TERM /UNTIL 6 AM THIS MORNING/...
A SHORTWAVE PASSING THROUGH COULD SPARK A FEW SHOWERS HOWEVER IT
WILL GENERALLY BE DRY THROUGH 6 AM WITH NO MAJOR CONCERNS. LOWS
MAINLY IN THE MID 60S.

&&

.SHORT TERM /6 AM THIS MORNING THROUGH SATURDAY/...
THURSDAY...A POTENT UPPER LOW WILL TRACK EAST ACROSS THE LOWER
MISSISSIPPI AND TENNESSEE VALLEYS ON THURSDAY...DAMPENING THE WEAK
UPPER RIDGING ACROSS THE SOUTHEAST STATES. AT THE SURFACE...A
BACKDOOR COLD FRONT WILL HAVE DESCENDED TO APPROXIMATELY THE NORTH
CAROLINA/SOUTH CAROLINA BORDER BY THURSDAY MORNING. ABUNDANT UPPER
LEVEL ENERGY ALONGSIDE AND DOWNSTREAM OF THE UPPER LOW WILL ASSIST
IN THE DEVELOPMENT OF A SURFACE WAVE ALONG THE LINGERING COLD
FRONT. NOTABLE DIFFERENCES IN NUMERICAL MODEL EVOLUTION OF THESE
SYNOPTIC SCALE FEATURES HAS CREATED SOME UNCERTAINTY IN FORECAST
DETAILS FOR THURSDAY...ESPECIALLY CONCERNING ORGANIZED SEVERE
WEATHER POTENTIAL. 12Z GFS SOLUTION TAKES THE BACKDOOR COLD FRONT
FARTHER SOUTH INTO THE FORECAST AREA THURSDAY AFTERNOON...WHILE
MAINTAINING A DEEPER UPPER LEVEL SYSTEM THROUGH THURSDAY NIGHT.
12Z NAM AND ECMWF SOLUTIONS ARE IN BETTER AGREEMENT...AND ALTHOUGH
HAVE PREFERRED NOT TO MAKE SWEEPING CHANGES TO THE ONGOING
FORECAST AT THIS TIME...HAVE GENERALLY LEANED TOWARD THESE MODEL
RUNS.

TWO MAIN AREAS OF CONVECTION COULD POTENTIALLY IMPACT THE FORECAST
AREA BY THURSDAY AFTERNOON/EVENING...ONE COMPLEX ORIGINATING ALONG
THE GULF COAST STATES COINCIDENT WITH THE UPPER LOW...AND ANOTHER
AREA OF CONVECTION CONCENTRATED ALONG THE LINGERING BOUNDARY TO
THE NORTH. DEEP MOISTURE WILL BE INCREASING ACROSS THE SOUTHEAST
STATES AHEAD OF THE APPROACHING SYSTEM...AND HAVE INDICATED
STEADILY INCREASING SHOWER/THUNDERSTORM CHANCES PEAKING IN THE 50
TO 60 PERCENT RANGE LATE THURSDAY INTO THURSDAY NIGHT. WILL
GENERALLY INDICATE HIGHEST POPS ACROSS THE NORTHERN HALF OF THE
FORECAST AREA CLOSEST TO ENHANCED CONVERGENCE AND FORCING NEAR THE
BACKDOOR FRONT. HIGH TEMPERATURES WILL BE A FEW DEGREES COOLER
THURSDAY AFTERNOON DUE TO INCREASED CLOUD COVER AND SCATTERED TO
NUMEROUS STORMS.

STORM PREDICTION CENTER HAS PLACED THE FORECAST AREA WITHIN A 5
PERCENT RISK FOR ORGANIZED SEVERE WEATHER ON THURSDAY...AS THE
DEGREE OF INSTABILITY REMAINS IN SOME QUESTION. MANY OF THE
SEVERE PARAMETERS ARE HIGHLY DEPENDENT ON WHICH MODEL SOLUTION IS
PREFERRED...WITH THE GFS GENERALLY MORE AGGRESSIVE. HOWEVER IT
HAS BEEN NOTED THAT BOTH GFS AND NAM HAVE ARRIVED WITH MORE
MARGINAL LOW LEVEL INSTABILITY FOR THURSDAY...POSSIBLY DUE TO THE
EFFECTS OF CLOUD COVER AND EARLIER CONVECTION. IN ADDITION...LOW
LEVEL WIND FIELDS ARE SOMEWHAT UNIMPRESSIVE EVEN IN THE MORE
AGGRESSIVE GFS SOLUTION. ISOLATED THUNDERSTORMS BECOMING STRONG TO
SEVERE REMAIN A POSSIBILITY REGARDLESS...HOWEVER COVERAGE AND
TIMING LEND MUCH UNCERTAINTY. AS A RESULT...REMAIN HESITANT TO
ADD SEVERE WORDING TO THE HAZARDOUS WEATHER OUTLOOK FOR THURSDAY
AND ALLOW SUBSEQUENT FORECAST SHIFTS TO REASSESS MODEL CONSISTENCY.

THURSDAY NIGHT/FRIDAY...THE UPPER LOW AND ASSOCIATED SURFACE WAVE
WILL STEADILY PROGRESS DIRECTLY OVER THE FORECAST AREA THURSDAY
NIGHT AND SLIP OFFSHORE BY FRIDAY MORNING. THESE DEPARTING
FEATURES WILL PULL THE LINGERING BACKDOOR FRONT THROUGH THE AREA
LATE MORNING/EARLY AFTERNOON FRIDAY. HAVE INDICATED RAIN CHANCES
DECREASING FROM SOUTHWEST TO NORTHEAST AFTER MIDNIGHT EARLY FRIDAY
MORNING...WHILE MAINTAINING SOLID CHANCE POPS THROUGH THE LATE
MORNING HOURS TO ACCOUNT FOR RESIDUAL DEEP MOISTURE AND
CONVERGENCE WITH THE FRONTAL PASSAGE. IF THE FRONT IS SLOWER IN
PROGRESSING SOUTH/SOUTHEAST...A FEW THUNDERSTORMS COULD DEVELOP
SOUTH OF INTERSTATE 16 IN SOUTHEAST GEORGIA. OTHERWISE JUST LIGHT
RAIN OR SHOWERS ARE EXPECTED FOR PART OF THE DAYTIME HOURS ON
FRIDAY. IN ADDITION...A TIGHT PRESSURE GRADIENT BETWEEN THE
SURFACE LOW PRESSURE MOVING INTO THE ATLANTIC LOW AND HIGH
PRESSURE BUILDING FROM THE GREAT LAKES WILL RESULT IN A BREEZY TO
WINDY DAY...WITH NORTHERLY WINDS OF 15 TO 25 MPH AND GUSTY.
CONSIDERABLY COOLER AIR WILL ADVECT INTO THE REGION WITHIN
NORTHERLY FLOW BEHIND THE FRONT...AND EXPECT HIGH TEMPERATURES TO
BE SUPPRESSED IN THE MID 60S NORTH TO THE LOWER 70S SOUTH.

FRIDAY NIGHT/SATURDAY...PERSISTENT COOL ADVECTION WITHIN BUILDING
CANADIAN HIGH PRESSURE WILL RESULT IN CONSIDERABLY LOWER TEMPERATURES
FRIDAY NIGHT. UNDER CLEARING SKIES...EXPECT TEMPERATURES TO FALL
INTO THE MID TO UPPER 40S FOR MOST LOCATIONS. SURFACE HIGH
PRESSURE WILL THEN CONTINUE TO SLIP OVER THE SOUTHEAST STATES ON
SATURDAY. AFTERNOON TEMPERATURES WILL BE A FEW DEGREES WARMER THAN
FRIDAY...YET STILL REMAIN COOL IN COMPARISON TO CONDITIONS DURING
THE PAST FEW WEEKS. EXPECT HIGHS TO GENERALLY REACH THE LOWER 70S
UNDER NORTHEAST FLOW AND CLEAR SKIES.

&&

.LONG TERM /SATURDAY NIGHT THROUGH WEDNESDAY/...
THE MEAN TROUGH WILL PERSIST IN THE EASTERN UNITED STATES THROUGH
THE PERIOD...WITH A SERIES OF COLD FRONTS TO CROSS THE AREA WITHIN
THE NW FLOW ALOFT. THERE IS NO CHANCE OF ANY RAINFALL WITH THE FIRST
FRONT SUNDAY NIGHT...WITH MAYBE A SMALL CHANCE WITH ANOTHER FRONT
TUESDAY. FOR NOW WE/LL CARRY A DRY FORECAST THROUGH THE MIDDLE OF
NEXT WEEK WITH PWATS WELL UNDER AN INCH TO OCCUR. PLENTY OF DAYTIME
INSOLATION AND DOWNSLOPE FLOW OFF THE MOUNTAINS WILL BOOST READINGS
UP NEAR OR ABOVE SEASONAL NORMS...WHILE NIGHTTIME COOL ADVECTION
BEHIND EACH FRONT ALLOWS FOR MINIMUM VALUES TO FALL BELOW NORMAL
THROUGH THE PERIOD.

&&

.AVIATION /06Z THURSDAY THROUGH MONDAY/...
VFR EXPECTED TO PREVAIL MOST OF THE PERIOD...ALTHOUGH UNCERTAINTY
INCREASES LATER THIS AFTERNOON AND EVENING AS THE NAM AND GFS
DIFFER QUITE A BIT ON PLACEMENT OF SYNOPTIC FEATURES. IF THE GFS IS
MORE ACCURATE...WILL BE SEEING MVFR CONDS BY 00Z AT KCHS AND BY
03Z AT KSAV. EITHER WAY...SH/TSTM CHANCES WILL BE ON THE INCREASE
THIS AFTERNOON AS AN UPPER LOW MOVES EAST INTO THE SOUTHEAST
STATES AND A BACKDOOR COLD FRONT MOVES SOUTH TOWARD THE AREA IN A
DECENTLY UNSTABLE/SHEARED ENVIRONMENT. IN FACT...SOME
STORMS...ESPECIALLY ACROSS SE GEORGIA...WILL BE STRONG TO SEVERE
WITH GUSTY WINDS AND LARGE HAIL. CB/S WILL COVER FOR
NOW...ALTHOUGH HAVE ALSO INCLUDED VCSH AT KCHS WHERE SLIGHTLY
GREATER COVERAGE IS EXPECTED THIS EVENING.

EXTENDED AVIATION OUTLOOK...MVFR OR LOWER CONDITIONS LIKELY INTO
FRIDAY AS A COLD FRONT MOVES THROUGH THE AREA.

&&

.MARINE...
SOME MODEST NOCTURNAL SURGING IS EXPECTED OVERNIGHT WITH THE
HIGHEST WINDS CONFINED TO THE GEORGIA OFFSHORE LEG. BOTH WINDS AND
SEAS WILL REMAIN BELOW SMALL CRAFT ADVISORY THRESHOLDS.

THURSDAY THROUGH MONDAY...A GENERAL SOUTHWEST FLOW ON THURSDAY
COULD BECOME MORE VARIABLE ACROSS NORTHERN PORTIONS OF THE MARINE
ZONES...AS A BACKDOOR FRONT LINGERS ALONG THE NORTHERN PERIPHERY
OF THE FORECAST AREA. MARINE CONDITIONS WILL THEN DETERIORATE
THURSDAY NIGHT INTO FRIDAY AS THE FRONT IS PULLED THROUGH THE
REGION EARLY FRIDAY. A TIGHTENED GRADIENT WILL DEVELOP IN THE
WAKE OF THE FRONT...AS LOW PRESSURE DEEPENS OVER THE GULF
STREAM AND HIGH PRESSURE BUILDS FROM THE NORTH. WINDS AND SEAS
WILL SURGE ACCORDINGLY...WITH SOLID SMALL CRAFT ADVISORY
CONDITIONS LIKELY ACROSS ALL MARINE ZONES ON FRIDAY. HAVE MADE
LITTLE CHANGES TO THE ONGOING FORECAST...INDICATING NORTH TO
NORTHEAST WINDS PEAKING AROUND 20 TO 30 KT...WITH SOME POTENTIAL
FOR MARGINAL GALES TO OCCUR ACROSS THE OUTER EDGES OF THE
CHARLESTON COUNTY WATERS AND THE OFFSHORE GEORGIA ZONE. SEAS WILL
BUILD AS HIGH AS 5 TO 7 FT WITHIN 20 NM OF THE COAST AND UP NEAR 9
OR 10 FT ACROSS THE OUTER GEORGIA WATERS. MARINE CONDITIONS WILL
SLOWLY IMPROVE SATURDAY AFTERNOON...AS SURFACE HIGH PRESSURE
SHIFTS OVER THE AREA THROUGH SUNDAY. A SECONDARY COLD FRONT WILL
CROSS THE WATERS SUNDAY NIGHT...AND WITH INCREASING COLD ADVECTION
WE MIGHT BE LOOKING AT MARGINAL SCA/S AGAIN FOR MONDAY NIGHT INTO
EARLY TUESDAY.

&&

.TIDES/COASTAL FLOODING...
THE COMBINATION OF THE PERIGEAN SPRING TIDE LATE THIS WEEK AND
MODERATE TO STRONG NORTH AND NE WINDS WILL LEAD TO POSITIVE TIDAL
DEPARTURES FRIDAY. AS A RESULT...THERE IS THE RISK OF AT LEAST
SHALLOW COASTAL FLOODING AROUND THE TIME OF THE EVENING HIGH TIDE.
WITH HIGHER THAN NORMAL SEAS TO OCCUR WE ALSO ANTICIPATE MINOR
FLOODING PROBLEMS.

RIP CURRENTS...THE SAME CONDITIONS THAT MAY CAUSE SHALLOW COASTAL
FLOODING/EROSION WILL LEAD TO AN ELEVATED RISK OF RIP CURRENTS AT
AREA BEACHES FRIDAY AND AGAIN ON SATURDAY.
