AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHARLESTON SC
433 PM EST SAT DEC 25 2010

.SYNOPSIS...
A COMPLEX LOW PRESSURE SYSTEM WILL MOVE OUT OF THE GULF OF MEXICO
AND UP THE SOUTHEAST COAST LATE TONIGHT. SIGNIFICANT MOISTURE WILL
WRAP AROUND THE BACK SIDE OF THE DEPARTING LOW ON SUNDAY BEFORE
DRIER HIGH PRESSURE FILTERS IN FROM THE NORTHWEST SUNDAY NIGHT
THROUGH TUESDAY. ATLANTIC HIGH PRESSURE WILL DELIVER MUCH MILDER
WEATHER TOWARD THE END OF NEXT WEEK.

&&

.NEAR TERM /UNTIL 6 AM SUNDAY MORNING/...
CURRENTLY AT THE SURFACE...A STRENGTHENING AREA OF LOW PRESSURE IS
LOCATED IN THE NORTHEASTERN GULF OF MEXICO...WITH A WARM FRONT
STRETCHING EASTWARD AND INTO THE NORTHERN FLORIDA PENINSULA. ALOFT A
SHORTWAVE TROUGH OVER THE WESTERN FLORIDA PANHANDLE IS BEGINNING TO
UNDERGO SOME PHASING WITH NORTHERN STREAM SHORTWAVE TROUGH ENTERING
NORTHERN MISSISSIPPI/NORTHERN ALABAMA. VISIBLE SATELLITE IMAGERY
SHOWS MOSTLY CLOUDY/CLOUDY CONDITIONS HAVE OVERSPREAD THE FORECAST
AREA...WITH RADAR IMAGERY IN COMBINATION WITH SURFACE OBSERVATIONS
INDICATING THAT SCATTERED RAIN SHOWERS ARE BEGINNING TO APPROACH
SOUTHWESTERN ZONES. MAIN NEAR TERM CONCERN FOR TONIGHT REVOLVES
AROUND PRECIP TYPE ISSUES.

TONIGHT...THE NORTHERN AND SOUTHERN STREAM SHORTWAVE TROUGHS WILL
PHASE ALLOWING FOR A DEEP UPPER LEVEL TROUGH TO CLOSE OFF OVER THE
TENNESSEE VALLEY. THIS WILL INDUCE EXPLOSIVE CYCLOGENESIS AS THE
AREA OF LOW PRESSURE TRACKS ACROSS THE NORTHERN FLORIDA PENINSULA
THIS EVENING AND OFF THE SOUTH CAROLINA AND GEORGIA COAST AFTER
MIDNIGHT. DEEP MOISTURE WILL CONTINUE TO INCREASE WITH H85 TO H5
CONDENSATION PRESSURE DEFICITS FALLING BELOW 30 MB ACROSS THE
ENTIRE FORECAST AREA. STRONG FORCING FOR ASCENT WILL OVERSPREAD
REGION WITH GUIDANCE SHOWING INCREDIBLY STRONG MID AND UPPER LEVEL
QG FORCING AS A RESULT OF THE SHORTWAVES PHASING AND STRONG UPPER
LEVEL DIVERGENCE IN THE RIGHT FRONT QUAD OF A 120+ KNOT H25 JET.
THIS MAKES OVERNIGHT POPS RELATIVELY EASY WITH PLENTY OF DEEP
MOISTURE IN PLACE...AND WILL CARRY CATEGORICAL POPS ALL LOCALES.

NOW ATTENTION TURNS TO THE PRECIP TYPE ISSUES ALONG WITH MESOSCALE
FORCING WHICH COULD CONTRIBUTE TO INCREASED SNOWFALL RATES IN AREAS
THAT SWITCH OVER QUICKLY. BOTH THE 12Z NAM/GFS SOUNDINGS INDICATE
THAT PRECIPITATION TYPE WILL REMAIN ALL RAIN THROUGH 06Z SUNDAY.
SOUNDING PROFILES THEN SHOW A GRADUAL CHANGE OVER FROM WEST TO EAST
ACROSS THE FORECAST AREA BETWEEN 06Z AND 12Z SUNDAY...WITH COASTAL
ZONES LIKELY REMAINING ALL RAIN THROUGH 12Z. ACROSS EXTREME
WESTERN/NORTHWESTERN ZONES...EXPECT AROUND A HALF INCH TO AN INCH OF
SLUSHY SNOW ACCUMULATION BY DAYBREAK. THERE IS THE POTENTIAL FOR
SLIGHTLY HIGHER AMOUNTS OVERNIGHT IF THE CHANGE OVER TO SNOW OCCURS
MORE QUICKLY THAN EXPECTED AND IS ABLE TO BENEFIT FROM SOME GOOD
MESOSCALE BANDING. THE MODEL SOLUTIONS ALL SHOW DECENT
FRONTOGENETICAL FORCING SETTING UP BENEATH A LAYER OF NEGATIVE
EQUIVALENT POTENTIAL VORTICITY WHICH COULD LEAD TO INCREASED
SNOWFALL RATES BETWEEN 06Z AND 12Z...BUT THIS FORCING IS LIFTING
NORTHEASTWARD ACROSS THE FORECAST AREA AS THE CHANGE OVER TO SNOW IS
OCCURRING. THEREFORE...DON/T ANTICIPATE THIS BECOMING A
PROBLEM...BUT WILL DEFINITELY BE SOMETHING TO WATCH CLOSELY
OVERNIGHT.

&&

.SHORT TERM /6 AM SUNDAY MORNING THROUGH TUESDAY/...
SUNDAY...THE DEEP UPPER LEVEL TROUGH AND CLOSED LOW OVER THE
TENNESSEE VALLEY WILL SHIFT INTO THE SOUTHEAST STATES...BRINGING
WITH IT TREMENDOUS MID AND UPPER LEVEL QG FORCING FOR ASCENT ALONG
WITH DEEPENING MOISTURE. AT THE SURFACE...THE DEEPENING AREA OF
LOW PRESSURE WILL RAPIDLY INTENSIFY AS IT LIFTS FROM A LOCATION
OFF THE CAROLINA COAST AT DAYBREAK TO JUST SOUTH OF NEW YORK CITY
BY SUNDAY EVENING. BOTH THE NAM AND GFS SOUNDING PROFILES SHOW THE
AIRMASS BECOMING SUFFICIENTLY COLD FOR ALL SNOW ACROSS THE ENTIRE
FORECAST AREA BY MID/LATE MORNING. THE QUESTION WITH RESPECT TO
PRECIP TYPE WILL REVOLVE AROUND THE DEPTH OF MOISTURE DURING THE
MORNING...AS THEIR WILL MOST LIKELY BE A BIT OF A BREAK IN THE
DEEP MOISTURE BETWEEN THE SYSTEM LIFTING OFF TO THE NORTHEAST AND
AWAY FROM THE FORECAST AREA AND THE ARRIVAL OF DEEPER MOISTURE
ASSOCIATED WITH THE DEEP UPPER LEVEL TROUGH ROTATING OVER THE
REGION. MODEL SOUNDINGS SHOW MOISTURE FAILING TO REACH THE -10C
LEVEL EARLY SUNDAY MORNING ACROSS COASTAL LOCALES...SO RAIN MAY
ACTUALLY TRANSITION TO DRIZZLE BETWEEN 12Z AND 15Z SUNDAY. WOULD
ANTICIPATE THAT THERE WILL BE ENOUGH FORCING AND LINGERING ICE
NUCLEI FROM THE DEPARTING STORM TO AT LEAST RESULT IN SOME SNOW
FLAKES IN THE AIR...SO WILL KEEP A MIX OF RAIN/SNOW FOR MAINLY
COASTAL LOCALES AND A BIT FURTHER INLAND IN SOUTHEAST GEORGIA
DURING THE EARLY MORNING. DEEPER MOISTURE WILL ARRIVE BACK INTO
THE FORECAST AREA BY LATE MORNING AND THROUGH THE AFTERNOON HOURS
IN ASSOCIATION WITH THE DEEP UPPER LEVEL TROUGH...SO EXPECT THAT
PRECIP TYPE WILL BE PRIMARILY SNOW ACROSS THEN ENTIRE FORECAST
AREA BY OR SHORTLY AFTER 15Z SUNDAY. MODEL SOLUTIONS SHOW UP TO
0.25 INCHES OF QPF OVER PORTIONS OF THE FORECAST AREA...BUT FEEL
THAT SNOW ACCUMULATIONS WILL LIKELY BE HAMPERED A BIT DUE TO
TEMPERATURES ABOVE THE FREEZING MARK THROUGH THE DAY AND INCOMING
SOLAR RADIATION ALTHOUGH STRONGLY FILTERED BY A DENSE OVERCAST.
THEREFORE...WILL LOOK FOR ROUGHLY 1 TO 3 INCHES ACROSS
NORTHWESTERN SOUTH CAROLINA ZONES...AROUND AN INCH ACROSS COASTAL
SOUTH CAROLINA ZONES AND PORTIONS OF SOUTHEAST GEORGIA...WITH NOT
MORE THAN A DUSTING GENERALLY SOUTH OF INTERSTATE 16.

BASED ON THE EXPECTED STORM TOTAL SNOW ACCUMULATIONS ACROSS THE
FORECAST AREA...WILL ISSUE A WINTER STORM WARNING FOR THE
NORTHWESTERN TIER OF ZONES IN SOUTH CAROLINA...WITH A WINTER WEATHER
ADVISORY FOR COASTAL SOUTH CAROLINA ZONES WRAPPING BACK INTO
PORTIONS OF SOUTHEAST GEORGIA. NOT ANTICIPATING ANY PROBLEMS SOUTH
OF I-16...SO NO HEADLINES NEEDED HERE...BUT AS ALWAYS WE WILL NEED
TO MONITOR THE DEVELOPMENT OF THIS STORM SYSTEM CLOSELY FOR ANY
NECESSARY CHANGES TO THE FORECAST.

LAKE WINDS...MUCH COLDER AIR MOVING OVER THE RELATIVELY WARMER
WATERS OF LAKE MOULTRIE WILL ENHANCE MIXING POTENTIAL INTO STRONG
LOW LEVEL WINDS. AS A RESULT...WEST TO NORTHWEST WINDS AT THE LAKE
SURFACE COULD APPROACH LAKE WIND ADVISORY CRITERIA ON SUNDAY...WITH
FREQUENT GUSTS UP TO 25 KT. A LAKE WIND ADVISORY MAY NEED TO BE ISSUED
LATER TONIGHT.

SUNDAY NIGHT...DEEP MOISTURE WILL QUICKLY PULL TO THE NORTHEAST...AS
THE DEEPENING COASTAL LOW TRACKS UP THE NEW ENGLAND COAST. MODELS
INDICATE LIGHT SNOW OR FLURRIES COULD LINGER FOR MAINLY THE SOUTH
CAROLINA COUNTIES AFTER SUNSET SUNDAY EVENING...BEFORE PRECIPITATION
SHIFTS OFF THE COAST AFTER MIDNIGHT. NOTICEABLY COLDER TEMPERATURES
ARE EXPECTED FOR SUNDAY NIGHT...WITH LOWS FALLING INTO THE 20
DEGREE RANGE.

MONDAY THROUGH TUESDAY...HIGH PRESSURE WILL SHIFT EASTWARD ON
MONDAY...WHILE THE AXIS OF THE UPPER TROUGH CROSSES INTO THE
ATLANTIC. TEMPERATURES ON MONDAY WILL AGAIN REMAIN FAR BELOW
SEASONAL NORMALS...WITH HIGHS IN THE LOW TO MID 40S AND LOW
TEMPERATURES IN THE 20S AWAY FROM THE IMMEDIATE COASTLINE. THE
SURFACE HIGH WILL THEN MOVE DIRECTLY OVER THE FORECAST AREA ON
TUESDAY...AT THE SAME TIME THAT UPPER RIDGING STRENGTHENS OVER
THE EAST COAST. THIS PATTERN CHANGE WILL SUPPORT GRADUALLY
MODERATING CONDITIONS INTO MID WEEK. HIGH TEMPERATURES ON TUESDAY
WILL REACH THE LOWER 50S UNDER CLEAR SKIES.

&&

.LONG TERM /TUESDAY NIGHT THROUGH SATURDAY/...
SIGNIFICANT MODERATION IN TEMPERATURES EXPECTED THROUGH MID
WEEK...AS COLD AIR ADVECTION SHUTS DOWN AND UPPER RIDGING
STRENGTHENS ACROSS THE REGION. RIDGING AT THE SURFACE AND ALOFT
WILL SET UP OVER THE ATLANTIC AND BRING WARM AND MOIST AIR INTO
GEORGIA AND THE CAROLINAS BY LATE WEEK. EXPECT HIGHS TO REACH
WELL INTO THE 50S ON WEDNESDAY...60S THURSDAY...AND PERHAPS AROUND
70 BY FRIDAY AND SATURDAY. ANY RAIN CHANCES APPEAR VERY SMALL
UNTIL A COLD FRONT APPROACHES SOMETIME NEXT WEEKEND.

&&

.AVIATION /20Z SATURDAY THROUGH THURSDAY/...
VFR CONDITIONS WILL PREVAIL THROUGH AT LEAST 00Z THIS EVENING.
CLOUDS WILL INCREASE THROUGH THE DAY WITH LOWERING CIGS INTO MVFR
TONIGHT AS A SIGNIFICANT LOW PRESSURE SYSTEM MOVES INTO THE AREA
FROM THE WEST. RAIN WILL SPREAD IN FROM THE SOUTHWEST WITH PRECIPITATION
BEGINNING AROUND 02-03Z. THE LOW PRESSURE SYSTEM WILL INTENSIFY OFF
THE COAST OVERNIGHT INCREASING NORTH TO NORTHWESTERLY WINDS TO
AROUND 10 KNOTS. CIGS WILL CONTINUE TO LOWER INTO IFR AND POSSIBLY
LIFR CONDITIONS AS DEEP LAYER MOISTURE INCREASES AFTER 05Z. THE
BIG QUESTION WILL BE WITH PRECIPITATION TYPE SUNDAY MORNING WHERE
SNOW MAY BEGIN TO MIX IN WITH RAIN AT BOTH SITES. BY THE AFTERNOON
ANY PRECIPITATION WILL LIKELY BE ALL SNOW. VSBYS WILL DROP IN ANY
SNOW SHOWERS. LAST...GUSTY WINDS BETWEEN 20 AND 25 KNOTS WILL BE
POSSIBLE AFTER 14Z AT SAV AS GEOSTROPHIC WINDS INCREASE.

EXTENDED AVIATION OUTLOOK...MVFR/IFR CIGS CONTINUING INTO SUNDAY
AFTERNOON. LOWER VSBYS POSSIBLE AT TIMES SUNDAY AFTERNOON IN SNOW
SHOWERS. VFR CONDITIONS TO RETURN SUNDAY EVENING THROUGH MUCH OF
NEXT WEEK.

&&

.MARINE...
A STRONG LOW SYSTEM WILL SHIFT OVER THE MARINE ZONES TONIGHT...THEN
QUICKLY INTENSIFY AND TRACK NORTHEAST UP THE COASTLINE ON SUNDAY. A
COMBINATION OF ENHANCED PRESSURE GRADIENTS...INTENSE LOW LEVEL
WIND FIELDS...AND IMPROVED MIXING PROFILES WITHIN STRONG COLD
ADVECTION...WILL SUPPORT HAZARDOUS MARINE CONDITIONS FOR ALL
WATERS THROUGH MONDAY.

EXPECT GALE FORCE WINDS FOR THE OUTER GEORGIA WATERS TONIGHT AND
THE NEARSHORE WATERS SOUTH OF EDISTO BY SUNDAY MORNING. HAVE
UPGRADED THE GALE WATCH TO A WARNING FOR THESE AREAS ACCORDINGLY.
WEST TO NORTHWEST FLOW 25 TO 35 KT WITH GUSTS TO 40 KT ARE
POSSIBLE WELL OFF THE GEORGIA COAST DURING THIS EVENT. THE RAPID
DEEPENING OF THE GULF STREAM LOW SYSTEM AND TIGHTENING PRESSURE
PATTERNS SUGGEST THIS SURGE IN WINDS AND SEAS COULD BE SUDDEN AND
INTENSE.

ALTHOUGH AN OCCASIONAL GUST TO GALE FORCE CANNOT BE RULED OUT FOR
THE NEARSHORE WATERS OFF THE CHARLESTON COUNTY COAST...THE LATEST
FORECAST TRACK OF THE LOW SYSTEM SUGGESTS WINDS WILL LIKELY REMAIN
AT HIGH END SMALL CRAFT ADVISORY THRESHOLDS. HAVE GONE AHEAD AND
INITIATED AN ADVISORY FOR THE NEARSHORE WATERS NORTH OF EDISTO TONIGHT
THROUGH MONDAY...AND THE CHARLESTON HARBOR SUNDAY THROUGH MONDAY.

NORTHWEST FLOW WILL DIMINISH BY EARLY TUESDAY...WITH FLAGS LIKELY
COMING DOWN AS A RESULT. MUCH LIGHTER WINDS AND SEAS ARE ANTICIPATED
LATER TUE INTO WED.
