AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHARLESTON SC
1231 AM EST TUE JAN 20 2009

.SYNOPSIS...
LOW PRES WILL DEVELOP ALONG A COLD FRONT OVER THE ATLC LATE TONIGHT
AND EARLY TUESDAY...THEN SHIFTS NE TO OFF THE MID ATLC COAST DURING
THE AFTERNOON. HIGH PRESSURE WILL THEN BUILD BACK INTO THE AREA
TUESDAY NIGHT THROUGH FRIDAY...BEFORE THE NEXT COLD FRONT MOVES
INTO THE REGION OVER THE UPCOMING WEEKEND.

&&

.NEAR TERM /UNTIL 6 AM THIS MORNING/...
LATE MONDAY EVENING...A COLD FRONT WAS ADVANCING INTO WESTERN
COUNTIES OF THE FORECAST AREA. SURFACE LOWS WERE NOTED ON THE
BOUNDARY OVER THE SC MIDLANDS...AND OVER SE GA. THESE LOWS ARE
EXPECTED TO CONSOLIDATE INTO A SINGLE DOMINANT LOW PRESSURE ALONG
THE GA/SC COAST...IN THE VICINITY OF THE SAVANNAH RIVER
ENTRANCE...OVERNIGHT/EARLY TUE.

AHEAD OF THE COLD FRONT...DEEP LAYER FORCING/ASCENT SUPPORTED
SHOWERS/ISOLATED THUNDERSTORMS POISED TO ADVANCE THROUGH SE
GA...MAINLY S OF I-16...BY MIDNIGHT-1 AM. THEN...WRAP AROUND
MOISTURE ASSOCIATED WITH AN AMPLIFYING UPPER WAVE WILL ARRIVE
ACROSS INLAND COUNTIES AS COLDER AIR SPREADS INTO THE REGION
OVERNIGHT. AS A RESULT...ANY RAIN SHOULD CHANGE TO SNOW
SHOWERS...WITH A SLIGHT CHANCE FOR A BRIEF PERIOD OF FREEZING RAIN
DURING THE CHANGEOVER...ACROSS INLAND COUNTIES BEFORE DAYBREAK.

GIVEN PROGRESS OF UPSTREAM COLD AIR...MOVED START TIMES OF ONGOING
WINTER WEATHER ADVISORIES FROM HAMPTON/ALLENDALE COUNTIES EAST TO
BERKELEY COUNTY A COUPLE OF HOURS FROM THE AFTERNOON
PACKAGE...STARTING AT 3 AM WEST AND 4 AM EAST. ALSO...EXPANDED THE
WINTER WEATHER ADVISORY TO INCLUDE JENKINS/SCREVEN COUNTIES IN SE
GA...WHERE SNOW SHOWERS MAY PRODUCE SOME ACCUMULATION ON THE S
PERIPHERY OF THE WRAP AROUND REGIME.

PER COLLABORATION WITH WFO ILM...OPTED NOT TO EXPAND A WINTER
WEATHER ADVISORY INTO CHARLESTON COUNTY WITH THE MON EVENING
PACKAGE...AS COLD AIR/CHANGEOVER TO SNOW SHOWERS WILL ARRIVE LATEST...
TUESDAY MORNING.

LAKE WINDS...STRONG COLD AIR ADVECTION WILL BEGIN OVER LAKE
MOULTRIE LATE TONIGHT AS A TROUGH OF LOW PRESSURE MOVES THROUGH
THE AREA AND A STRONG STORM SYSTEM BEGINS TO ORGANIZE OFF THE
CAROLINA COAST. SUSTAINED WINDS OF 20 KNOTS WITH GUSTS TO 25 KNOTS
ARE EXPECTED LATE TONIGHT...THEREFORE WILL ISSUE A LAKE WIND
ADVISORY FOR LAKE MOULTRIE.

&&

.SHORT TERM /6 AM THIS MORNING THROUGH 6 PM TODAY/...
WE HAVE INITIATED A WINTER WEATHER ADVISORY FOR SNOW ACROSS OUR
INLAND SC COUNTIES STARTING TUESDAY MORNING. AT THIS TIME HOWEVER
THAT DOES NOT INCLUDE CHARLESTON OR BEAUFORT COUNTIES...BUT THIS
COULD CHANGE DEPENDING UPON THE EVOLUTION OF THE SURFACE LOW AS IT
REACHES THE ATLC AND THE STRENGTH OF THE UPPER SHORT WAVE AND
ASSOCIATED DYNAMICS.

THE SURFACE LOW WILL STRENGTHEN AS IT MOVES ACROSS THE GULF STREAM
WATERS TUESDAY MORNING...WITH A CONTINUED INFLUX OF COLD AIR
MOVING IN FROM THE NW IN ITS WAKE. INDICATIONS ARE THAT ANY LIGHT
RAINS AND/OR MIXED PRECIP IN THE MORNING WILL CHANGE OVER TO ALL
SNOW BY AFTERNOON...AS THICKNESS...CROSS-SECTIONS...SOUNDINGS AND
WET BULBS ALL SUPPORT FROZEN PRECIP OVERSPREADING THE AREA.

AT 12Z...CONDITIONS OVERALL ARE TOO WARM AND TOO DRY TO SUPPORT
ANYTHING MORE THAN A LITTLE LIGHT RAIN...SNOW AND/OR FREEZING RAIN.

FROM 15Z TO 21Z...THE COLDER AIR IS OVERSPREADING THE AREA...WITH
A GRADUAL INCREASE IN MOISTURE. WHILE THE -10 TO -20C ICE GROWTH
ZONE HAS MOSTLY LESS THAN 80 PERCENT RH EARLY IN THIS TIME
PERIOD...IT DOES INCREASE TO AROUND 80 PERCENT OVER NORTHERN AND
WESTERN AREA BY AFTERNOON. SIGNIFICANT QG FORCING AT BOTH 700-500
MB AND 500-300 MB IS OCCURRING...WITH WEAK TO MODERATE LOW-MID
FRONTOGENESIS. ALSO...A 500-300 MB JET MOVES ACROSS THE AREA
DURING THE MORNING AND EARLY AFTERNOON. CROSS-SECTIONS ALSO SHOW
POSSIBLE BANDING OF SNOW DURING THIS TIME...WITH SATURATED EPV
ALONG WITH THE FRONTOGENESIS. THIS IS FURTHER SUPPORTED BY THE
ISENTROPIC TROWEL ANALYSIS WHICH SHOWS WEAK ISENTROPIC LIFT AT THE
290 AND 295K SURFACES DURING TUESDAY AFTERNOON...IN SYNC WITH THE
UPWARD OMEGA FIELDS.

GARCIA TECHNIQUE YIELDS ABOUT 1/2 TO 1 INCH OF SNOWFALL ACROSS
BEREKLEY...DORCHESTER...INLAND COLLETON...HAMPTON AND ALLENDALE
COUNTIES. HOWEVER...THE GROUND IS RELATIVELY WARM...WITH RECENT
SOIL TEMP AT KCHS STILL NEAR 50 DEGREES. WHILE THIS MIGHT POINT TO
SLIGHTLY LESS AMOUNTS...GIVEN THE POTENTIAL FOR HEAVIER BURSTS OF
SNOW WITH POSSIBLE CONVECTIVE BANDING...AND DECREASE IN SNOW
AMOUNTS DUE TO THE WARM GROUND SHOULD BE COMPENSATED FOR BY THE
POSSIBLE HEAVIER SNOWFALL. IN ADDITION...THE NW FETCH IS OFF LAKE
MOULTRIE AND LAKE MARION...OR FROM ABOUT 300-310 DEGREES.
TEMPERATURE DIFFERENCE BETWEEN THE AIR AND THE LAKE WILL BE ABOUT
10-12 DEGREES...WHICH LOOKS TO BE ENOUGH TO ALLOW FOR THE
POSSIBILITY OF A BAND OF SNOW DEVELOPING OVER THE LAKE WATERS
/SIMILAR TO LAKE EFFECT SNOWS IN THE GREAT LAKES/. SHOULD THIS
INDEED BECOME REALIZED...THEN SNOW AMOUNTS COULD BE LOCALLY HIGHER
DOWNWIND FROM THE LAKES.

FURTHER SOUTH AND EAST...WE HAVE OPTED TO KEEP CHARLESTON AND
BEAUFORT COUNTIES OUT OF THE ADVISORY. THE CURRENT THINKING IS
THAT THE BEST FORCING AND MOISTURE WILL REMAIN JUST NW OF BEAUFORT
COUNTY...AND WHILE WE DID CONSIDER INCLUDING CHARLESTON COUNTY IN
THE EARLIER ADVISORY...FOR COORDINATION PURPOSES WITH WFO ILM...WE
HAVE OPTED TO LEAVE THEM OUT AS WELL. THIS COULD CHANGE LATER
TONIGHT AFTER WE GET A BETTER HANDLE ON HOW THIS UNUSUAL SITUATION
WILL EVOLVE.

THE ADVISORY MAY NEED TO BE EXPANDED FURTHER SOUTH AND EAST LATER
TONIGHT OR EARLY TUESDAY...AND THERE IS EVEN THE POTENTIAL FOR AN
UPGRADE TO A WARNING. WHILE WE DO NOT EXPECT TO REACH OUR CRITERIA
OF 2 INCH SNOWFALL IN 12 HOURS...IT COULD BE PRUDENT TO ISSUE THE
WARNING FOR THE IMPACT...GIVEN HOW UNUSUAL THIS SITUATION IS.

MOST OF THE SNOWFALL WILL OCCUR ACROSS GRASSY SURFACES...ROOF TOPS
AND TREES...BUT IF HEAVIER SNOW BANDS DEVELOP...THEN SOME
ROADS...BRIDGES AND OVERPASSES COULD ALSO BECOME COVERED OR AT
LEAST SLICK.

THE SOUTHERN EXTENT OF THE SNOW WILL BE MAINLY THE I-16 CORRIDOR
IN SE GA...WITH THE POSSIBILITY OF FLURRIES EVEN AS FAR SOUTH AS
SAVANNAH...TYBEE ISLAND AND STATESBORO TUESDAY MORNING. SNOW WILL
TAPER OFF FROM SW TO NE DURING THE MID AND LATE AFTERNOON HOURS ON
TUESDAY AS THE ATLC LOW PULLS FURTHER AWAY...AND THE SHORT WAVE
BEGINS ITS EXIT OF THE AREA.

LITTLE CHANGE IN TEMPS ARE EXPECTED ACROSS NORTHERN AREAS ON
TUESDAY...WITH HIGHS GENERALLY IN THE 30S. CENTRAL AREAS WILL
REACH ONLY INTO THE LOWER 40S...WHILE OUR SOUTHERN AREAS WILL BE
THE WARMEST WITH READINGS IN THE MID TO UPPER 40S WHERE THE BEST
INSOLATION WILL OCCUR.

LAKE WINDS...CONTINUED STRONG COLD AIR ADVECTION OVER LAKE
MOULTRIE TUESDAY ACROSS THE WARMER LAKE WATERS WILL RESULT IN
SUSTAINED WINDS OF 20 KNOTS WITH GUSTS TO 25 KNOTS TUESDAY...THUS
A CONTINUATION OF THE LAKE WIND ADVISORY FOR LAKE MOULTRIE.

&&

.LONG TERM /TONIGHT THROUGH MONDAY/...
MEDIUM RANGE GUIDANCE IS IN GOOD AGREEMENT THROUGH THE EXTENDED
PERIOD THIS AFTERNOON...WITH ONLY A FEW MINOR DIFFERENCES NOTED OVER
THE WEEKEND AND INTO EARLY NEXT WEEK.

THE STRONG STORM SYSTEM WILL CONTINUE TO TRACK NORTHEASTWARD AND
AWAY FROM THE AREA TUESDAY NIGHT...WITH HIGH PRESSURE THEN BEGINNING
TO BUILD BACK INTO THE REGION. HAVE MENTIONED A SLIGHT CHANCE OF
FLURRIES IN THE EVENING ACROSS FAR NORTHERN ZONES AS DEEP
MOISTURE...SUFFICIENTLY COLD AIR ALOFT...AND DECENT FETCH OFF OF
LAKE MOULTRIE MAY BE ENOUGH TO KEEP A FEW SNOW FLAKES AROUND. ANY
LINGERING FLURRIES OR LIGHT SNOW SHOWERS SHOULD END IN THE
EVENING...WITH PRECIPITATION FREE WEATHER ANTICIPATED AFTER
MIDNIGHT.

HIGH PRESSURE WILL THEN BUILD BACK INTO THE AREA WEDNESDAY THROUGH
FRIDAY...RESULTING IN RAIN FREE WEATHER ACROSS THE REGION.

MODELS ARE IN GOOD AGREEMENT BRINGING A COLD FRONT SLOWLY THROUGH
THE REGION FRIDAY NIGHT THROUGH SATURDAY NIGHT...SO WILL CARRY
SLIGHT CHANCE/LOW CHANCE POPS FOR NOW UNTIL GUIDANCE GETS A BETTER
HANDLE ON TIMING DETAILS. HIGH PRESSURE IS THEN EXPECTED TO BUILD
FROM THE NORTH SUNDAY THROUGH MONDAY...WITH RAIN FREE WEATHER
ANTICIPATED.

&&

.AVIATION /06Z TUESDAY THROUGH SATURDAY/...
VERY LIGHT RAIN IN THE VICINITY OF KCHS WILL MOVE QUICKLY OFF TO
THE NORTHEAST THROUGH 07Z WITH NO REDUCTIONS IN VISIBILITY.
CEILINGS ARE POISED TO BEGIN A SLOW DECLINE ACROSS THE REGION
OVERNIGHT AS LOW PRESSURE MOVES OFF THE SOUTH CAROLINA COAST AND
CYCLONIC FLOW IN ITS WAKE DRIVES COLDER AIR INTO THE REGION.

KCHS...EXPECT CEILINGS TO REACH LOW-END MVFR BY SUNRISE AS LIGHT
SNOW BLOSSOMS OVER THE MIDLANDS. AS THE LOW PULLS AWAY A BATCH OF
LIGHT SNOW IS EXPECTED TO DRIVE SOUTHEAST TOWARDS THE KCHS
TERMINAL...POSSIBLY DROPPING VISIBILITIES DOWN MVFR THRESHOLDS...
ROUGHLY IN THE 14-18Z TIME FRAME. SOME MINOR ACCUMULATIONS WILL BE
POSSIBLE AT THE TERMINAL...MAINLY ON GRASSY AREAS. THE SNOW WILL
GRADUALLY TAPPER TO FLURRIES DURING THE AFTERNOON BUT LOW CLOUDS
WILL REMAIN THROUGH MUCH OF THE DAY BEFORE SCOURING OUT THIS
EVENING.

KSAV...CAREFULLY WATCHING LARGE PRESSURE RISES ACROSS THE FLORIDA
PANHANDLE WHERE WINDS HAVE BEEN GUSTING CLOSE TO 20 KT. LOOKS LIKE
THE BULK OF THESE WINDS SHOULD REMAIN SOUTH OF KSAV BUT A DISTINCT
INCREASE IN SPEEDS IS LIKELY OVER THE NEXT FEW HOURS. CEILINGS
WILL ALSO DROP DOWN TO HIGH-END MVFR BY 10Z OR SO. NO PRECIPITATION
IS EXPECTED AT THE KSAV TERMINAL OUTSIDE OF A FEW FLURRIES THIS
MORNING...BUT CERTAINLY NOT ENOUGH TO INCLUDE A MENTION ON THE 06Z
TAF. LOW CLOUDS WILL PERSIST THROUGH MUCH OF THE AFTERNOON BEFORE
SOURING OUT THIS EVENING.

EXTENDED AVIATION OUTLOOK...VFR CONDITIONS ARE EXPECTED THROUGH
FRIDAY NIGHT. COULD SEE MVFR CONDITIONS RETURN SATURDAY AS A COLD
FRONT PUSHES INTO THE AREA.

&&

.MARINE...
A DEEPENING SURFACE TROUGH WAS APPROACHING THE COASTAL WATERS LATE
MON EVENING...AND WINDS ACROSS THE COASTAL WATERS WILL INCREASE
SIGNIFICANTLY OVERNIGHT AS SURFACE LOW PRESSURE CONSOLIDATES AND
INTENSIFIES NEAR THE ENTRANCE TO THE SAVANNAH RIVER. DUE THE
MON EVENING TRENDS...SUGGESTING A FASTER SYSTEM EVOLUTION...MOVED
UP THE START TIMES FOR ONGOING SMALL CRAFT ADVISORIES A COUPLE OF
HOURS FROM THE PREVIOUS FORECAST.

IN RESPONSE TO DEEPENING LOW PRESSURE ADVANCING NE...SCA
CONDITIONS WILL CONTINUE TO IMPACT THE MARINE AREA THROUGH TUESDAY
EVENING AS STRONG COLD AIR ADVECTION POURS INTO THE REGION.
THERE IS A SLIGHT CHANCE FOR A BRIEF PERIOD OF GALE FORCE GUSTS
ACROSS THE OUTER GA WATERS AND PERHAPS EVEN ACROSS THE SC
NEARSHORE WATERS TUES INTO TUE NIGHT.

HIGH PRESSURE WILL BUILD BACK INTO THE REGION WEDNESDAY THROUGH
FRIDAY...WITH THE NEXT COLD FRONT EXPECTED TO APPROACH FROM THE WEST
FRIDAY NIGHT AND PUSH THROUGH THE MARINE AREA ON SATURDAY. SEAS MAY
REMAIN IN THE SMALL CRAFT RANGE ACROSS THE OUTER GEORGIA WATERS
EARLY WEDNESDAY...OTHERWISE WINDS AND SEAS ARE EXPECTED TO REMAIN
BELOW HEADLINE THRESHOLDS WEDNESDAY THROUGH SATURDAY.
