AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREENVILLE-SPARTANBURG SC
1001 PM EST FRI FEB 10 2006
.SHORT TERM (REST OF TONIGHT)...
REGIONAL RADARS INDICATE PRECIP EXPANDING TO OUR SOUTHWEST...WITH
-RA BEING REPORTED IN ATLANTA OVER THE PAST COUPLE OF HOURS. THIS
APPEARS TO BE ASSOCIATED WITH INITIAL WAVE OF LOW LEVEL UPGLIDE AND
IS SOMEWHAT DETACHED FROM THE MAIN AREA OF FORCING/PRECIP...WHICH IS
CURRENTLY OVER MIDDLE TN/AL/MS. THIS PROGRESSION IS SLOWER THAN
PREVIOUSLY FORECAST...WHICH THE 00Z NAM HAS PICKED UP ON.
THEREFORE...WILL SLOW THE TIMING OF PRECIP CLOSER TO THAT OF THE
LATEST NAM.
OTHERWISE...CONCERNS ABOUND REGARDING THE POTENTIAL FOR WINTER
PRECIP. FOR ONE THING...DEWPOINTS HAVE BEEN MUCH SLOWER TO RECOVER
THAN THE MODELS HAVE SUGGESTED...WITH SURFACE TD CONTINUING TO RUN
ABOUT 10 DEGREES F ABOVE THAT OF THE 18Z MODEL RUNS. IN FACT...
COMPARING THE 00Z GSO SOUNDING WITH A FORECAST SOUNDING FROM THE 18Z
NAM INDICATES THE ENTIRE BOUNDARY LAYER IS MUCH DRIER THAN FORECAST.
THIS HAS OBVIOUS CONNOTATIONS FOR EVAPORATIONAL COOLING POTENTIAL
ONCE PRECIP BEGINS. ON THE OTHER HAND...A THICK CIRRUS/AC CANOPY IS
PUTTING THE SKIDS ON RADIATIONAL COOLING. AS A RESULT...WET BULB
TEMPS ARE MAINTAINING IN THE UPPER 30S ACROSS MUCH OF THE UNWARNED
AREA. DEWPOINTS SHOULD CONTINUE TO GRADUALLY CLIMB OVERNIGHT...WITH
ONLY MODEST COOLING ANTICIPATED PRIOR TO PRECIP ONSET. THEREFORE...
FEEL THAT THE CURRENT WARNING/ADVISORY SHOULD HOLD...EXCEPT FOR THE
NW PIEDMONT...WHERE WET BULBS ARE HOVERING IN THE LOWER TO MIDDLE
30S. WE WILL ADD ROWAN...DAVIE...AND IREDELL COUNTIES TO THE
ADVISORY.
ONCE PRECIP BEGINS...THERE WILL BE A LOW LEVEL AGEOSTROPHIC ADJUSTMENT
(IN-SITU DAMMING) IN RESPONSE TO THE EVAPORATIONAL COOLING.
DEPENDING ON THE STRENGTH OF THE RESULTANT BARRIER JET...THIS COULD
PROVIDE AN ADDITIONAL SOURCE OF COOLING THAT THE MODELS ARE
DOWNPLAYING. IT IS SOMEWHAT WORRISOME THAT THE NAM HAS HAD A
TENDENCY TO UNDER-FORECAST THE MAGNITUDE OF COLD AIR IN CAD/WINTER
PRECIP SITUATIONS SO FAR THIS YEAR...BUT CONSIDERING THE STRENGTH
(OR LACK THEREOF) OF THE PARENT HIGH...I JUST CAN/T BRING MYSELF TO
GO WITH A SIGNIFICANTLY COOLER SOLUTION THAN THE MODEL IS
FORECASTING. IN ADDITION...HAVE MAJOR CONCERNS ABOUT SNOW/LIQUID
RATIOS CONSIDERING THAT ANY SNOW WILL BE OF THE SLOPPY...WET
VARIETY...AND THERE WILL BE PLENTY OF RAIN MIXING IN OUTSIDE OF THE
CURRENT WARNING AREA. ON THE OTHER HAND...THERE WILL BE THE POTENTIAL
FOR MESOSCALE BANDING IN RESPONSE TO RATHER STRONG LOW-TO-MID LEVEL
FRONTOGENETICAL FORCING TO PUT DOWN WARNING CRITERIA SNOW IN A VERY
SHORT PERIOD OF TIME (AND THIS IS POSSIBLE ALMOST ANYWHERE IN THE
CWFA...MAINLY DURING THE 2ND PERIOD.) HOWEVER...FORECASTING
WHEN/WHERE THAT MAY OCCUR IS MORE OR LESS AN IMPOSSIBILITY THIS FAR
OUT.
IN A NUTSHELL...OTHER THAN THE FEW CHANGES ALREADY MENTIONED...JUST
CAN/T FIND TOO MUCH IN THE CURRENT FORECAST TO ARGUE WITH ATTM.

.PREVIOUS DISCUSSION...
(ISSUED 310 PM EST FRI FEB 10 2006)
SHORT TERM (TONIGHT THROUGH MONDAY)...
TONIGHT AND SAT...
COMPLICATED FORECAST IN THE NEAR TERM AS PTYPE AND SNOW AMOUNTS ARE
MAIN CONCERN. 12Z NAM AND GFS CONTINUE TO HAVE SIMILAR SYNOPTIC
SOLUTION OF SFC LOW TRACKING ALONG GULF COAST. BOTH MODELS SWING THE
LOW NE OVERNIGHT AND THEN ACROSS THE LOWLANDS OF SC ON SAT.
HOWEVER...RATHER SIGNIFICANT DIFFERENCES OCCUR IN THE VERTICAL AS NAM
PARTIAL THICKNESSES LOWER ESPECIALLY IN THE 1000-850MB LAYER.
LOCALLY RUN WRF EVEN COLDER IN THE LOWER LEVELS. BELIEVE THAT THE
NAM/WRF ARE DEVELOPING MORE COLD AIR DAMMING (CAD) DUE TO
EVAPORATIVE COOLING AS THE PRECIP BEGINS. NAM USUALLY BETTER WITH
CAD...SO WILL TREND TOWARD THE COLDER NAM SOLUTION. DID MODIFY MY
NOMOGRAM TOOL SOME WITH GFS SO AS TO NOT TOTALLY BUY INTO NAM. THIS
RESULTS IN RAIN/SNOW LINE FARTHER S INTO NE GA...UPSTATE SC AND THE
PIEDMONT OF NC. LOOKS LIKE THERE IS A GOOD CHANCE FOR WARNING SNOW
(3 OR MORE INCHES)ACROSS ALL OF OUR NC MOUNTAIN ZONES...THE SC
MOUNTAIN ZONES...RABUN COUNTY GA INTO THE NC FOOTHILLS. WILL HOIST A
WINTER STORM WARNING FOR ZONES CURRENTLY UNDER A WATCH. WILL
SURROUND THE WARNING ZONES WITH A WINTER WEATHER ADVISORY WHICH WILL
INCLUDE HABERSHAM/STEVENS IN GA E THROUGH THE SC UPSTATE AND THEN N
THROUGH THE WESTERN PIEDMONT OF NC INTO THE FOOTHILLS. FROM LATE
TONIGHT THROUGH SAT...EXPECT 3-5 INCHES OF SNOW NORTHERN/CENTRAL
MOUNTAINS...WITH HIGHER AMOUNTS AT ELEVATION. EXPECT 2-4 INCHES IN
REMAINDER OF WARNING AREA AS WILL NOT MAXIMIZE QPF DUE TO MIXING
WITH RAIN. ADVISORY ZONES PROBABLY 1-2 INCHES...THOUGH SOUTHERN
PORTIONS OF LARGE COUNTIES LIKE GREENVILLE AND SPARTANBURG ONLY A
TRACE. PROBABLY JUST A TRACE CHARLOTTE METRO...THOUGH COULD NOT RULE
OUT A DUSTING OF WET SNOW ON GRASSY AREAS.
EXPECT PRECIP TO BEGIN GENERALLY AFTER MIDNIGHT AND THEN QUICKLY
OVERSPREAD THE AREA. PRECIP MAY BEGIN AS RAIN IN WARNING/ADVISORY
AREA...BUT EVAPORATIVE COOLING SHOULD COOL THE VERTICAL FOR A
CHANGEOVER TO SNOW. HEAVIEST PRECIP APPEARS TO BE FROM ABOUT 10Z SAT
UNTIL ABOUT 18Z OR SO.
USED 3 HOURLY GFS TEMPS TO POPULATE GRIDS...BUT MADE SOME
ADJUSTMENTS AROUND 12Z AS EXPECT MORE EVAP COOLING EFFECTS THAN
INDICATED BY MOS NUMBERS.
SNOW SHOWERS CONTINUE OVER THE MTNS SAT NITE AND SUNDAY AS EVENT
CHANGES TO A NW FLOW SNOW SCENARIO. FLOW IS NOT VERY STRONG BUT
CYCLONIC. ALSO GOOD LOW LEVEL INSTABILITY WITH STEEP LAPSE RATES
WILL LEAD TO PERIODS OF HEAVY SNOW SHOWERS OVER THE WARNING AREA.
ICE CRYSTAL GROWTH ZONE DROPS QUITE LOW AS WELL WITH VERY COLD TEMPS
MOVING INTO THE AREA. BEST SNOW CHANCES RETREAT TO THE COUNTIES
ALONG THE TN BORDER DURING THE DAY SUNDAY AND CONTINUE TO DIMINISH
SUNDAY NIGHT. SNOW SHOULD END COMPLETELY BY MONDAY AFTERNOON. LOOKS
LIKE ANOTHER 2 TO 4 INCHES OVER THE HEAVY SNOW WARNING AREA SATURDAY
NIGHT AND SUNDAY...WITH ANOTHER INCH OR SO OVER THE SRN MTNS AND NC
FOOTHILLS SATURDAY NIGHT.
OUTSIDE OF THE MTNS...PRECIP SHOULD END AS SNOW NORTH OR EVEN A SNOW
MIX SATURDAY NIGHT AS COLD MID LEVEL AIR MOVES IN. LITTLE TO NO
ACCUMULATIONS EXPECTED OUTSIDE OF THE WARNING/ADVISORY AREA. WX
REMAINS DRY THRU MONDAY THESE AREAS.
TEMPS WELL BELOW NORMAL AND QUITE CHILLY SUNDAY AND MONDAY WITH CAA
CONTINUING.
LONG TERM (MONDAY NIGHT THROUGH FRIDAY)...
FAIRLY TRANQUIL WX TUE THRU FRI AS HEIGHTS RISE SIGNIFICANTLY WHEN
RIDGING SFC AND ALOFT BUILD INTO THE AREA. FLOW BECOMES MORE ZONAL
TOWARD THE END OF THE PERIOD AND SFC HIGH MOVES OFF THE EAST COAST.
SWLY FLOW DEVELOPS INCREASING GULF MOISTURE OVER THE AREA. TEMPS
RISE TO NEAR THEN ABOVE NORMAL. SFC FNT MOVES TOWARD THE AREA THU
BUT STALLS TO OUR NORTH FRIDAY. THIS MEANS DRY WX TUE THEN SLIGHT
CHC TO LOW CHC POP WED THRU FRI AS MOISTURE INCREASES AND WWA
CONTINUES.
AVIATION...
18Z TAF PACKAGE DOMINATED BY LOWERING CEILINGS UNTIL AFTER
MIDNIGHT...THEN CEILINGS PROJECTED TO DROP RAPIDLY AS WARM ADVECTION
AND UPGLIDE SHUNT MOISTURE UP OUR WAY AHEAD OF APPROACHING CYCLONE.
PRECIPITATION SHIELD SHOULD BE INTO OUR WESTERN AREAS BY
DAYBREAK...AND WE EDGED INTO THE EVENT WITH TEMPO GROUPS IN THE
PREDAWN FOR THE FAR WESTERN TAF SITES...WITH CATEGORICAL
PRECIPITATION AT ALL TAF SITES THROUGH THE ENTIRE OUTLOOK PERIOD.
VISIBILITY COULD DROP TO IFR LEVEL AT KAVL IN THE PREDAWN WHEN FIRST
ROUND OF HEAVIER PRECIPITATION...WHICH SHOULD BE MOSTLY SNOW
THERE...GETS CRANKED UP. OUTSIDE THE MOUNTAINS...CEILINGS SHOULD
FLIRT WITH IFR BY THE BEGINNING OF THE OUTLOOK PERIOD WITH IFR
CEILINGS AND MVFR VISIBILITIES ADVERTISED. PRECIPITATION INDICATED
AS RAIN/SNOW MIXTURE ALL NON-MOUNTAIN TAF SITES FROM THE PREDAWN
THROUGH THE END OF OUTLOOK AT KAND...ALTHOUGH THE FURTHER ONE GOES
NORTH IN OUR CWFA (I.E. KHKY)...THE MORE LIKELY IT IS PRECIPITATION
TYPE WILL BE ALL SNOW.
