AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREENVILLE-SPARTANBURG SC
1249 PM EST FRI NOV 9 2012

.SYNOPSIS...
A DRY SOUTHERLY FLOW WILL RESULT IN A WARMING TREND THIS WEEKEND.
SHOWER CHANCES WILL INCREASE MONDAY AND MONDAY NIGHT AHEAD OF AN
APPROACHING COLD FRONT. COOLER HIGH PRESSURE WILL SETTLE OVER THE
AREA BY MIDWEEK.

&&

.NEAR TERM /THROUGH TONIGHT/...
AT 1230 PM EST FRIDAY... RIDGE ALOFT AND SURFACE HIGH PRESSURE WILL
CONTRIBUTE TO SUNNY WEATHER DURING REMAINDER OF THE AFTERNOON AND
CLEAR SKY OVERNIGHT. A FEW HIGH CLOUDS POSSIBLE ON SATURDAY... BUT
MOSTLY SUNNY WEATHER WILL CONTINUE. NO SIGNIFICANT CHANGES TO
TEMPERATURE FORECASTS AT THIS TIME.

PREVIOUS DISCUSSION...
AS OF 230 AM ON FRIDAY...EXPECT CONTINUED DRY CONDITIONS WITH
MODERATING TEMPERATURES ACROSS THE REGION TODAY AS AN UPPER RIDGE
BUILDS IN FROM THE WEST AND SURFACE HIGH PRESSURE REMAIN ANCHORED
OVER THE SOUTHEAST. MODEL TIME HEIGHTS AND SOUNDING INDICATE THAT AN
AIR MASS WILL REMAIN DRY AND SUPPRESSED. THIS WILL LEAD TO CONTINUED
CLEAR SKIES UNDER THE HIGH PRESSURE. TEMPERATURES WILL BE NEAR OR
1-2 DEGREES BELOW NORMAL WITH AFTERNOON HIGHS IN THE MID 60S OVER
THE PIEDMONT AND 50S IN THE HIGHER TERRAIN. WINDS WILL BECOME LIGHT
SOUTHERLY THIS AFTERNOON AS THE CENTER OF HIGH SLOWLY SHIFT EAST.
TONIGHT...HIGH PRESSURE WILL REMAIN IN PLACE WITH AN UPPER RIDGE
AMPLIFYING OVER THE REGION. OVERNIGHT LOWS WILL BE A FEW DEGREES
WARMER THAN THIS MORNING AS THICKNESS VALUES INCREASE A BIT. STILL
GOOD RADIATIONAL COOLING MAY RESULT IN PATCHY MORNING FROST OVER THE
PORTIONS OF NE GEORGIA...SC PIEDMONT AND NC FOOTHILLS.
HENCE...ANOTHER FROST ADVISORY WILL HAVE TO BE CONSIDERED.

&&

.SHORT TERM /SATURDAY THROUGH SUNDAY NIGHT/...
AS OF 245 AM EST FRIDAY...A DOMINANT RIDGE AXIS OVER THE FORECAST
AREA ON SAT WILL MIGRATE OFF THE EASTERN SEABOARD ON SUNDAY. VERY
DRY PROFILES WILL REMAIN IN PLACE FOR MOST OF THE WEEKEND. THE FULL
SUNSHINE AND STEADILY REBOUNDING THICKNESSES WILL SUPPORT MAX
TEMPERATURES APPROACHING 10 DEGREES ABOVE NORMAL IN SOME PLACES.

SOUTHERLY RETURN FLOW DEVELOPING ON SUNDAY WILL STRENGTHEN THROUGH
SUNDAY NIGHT AND BRING LOW LEVEL MOISTURE BACK TO THE SOUTHERN
APPALACHIANS DURING THE EARLY MORNING HOURS MONDAY...ALONG WITH
INCREASING WINDS AT THE HIGHER ELEVATIONS OF THE SW MTNS. WILL PUSH
POPS UP INTO THE SCHC TO LOW END CHC RANGE BEFORE DAYBREAK IN S TO
SE UPSLOPE SECTIONS OF THE SRN MTNS.

&&

.LONG TERM /MONDAY THROUGH THURSDAY/...
AS OF 210 AM FRIDAY...THE LATEST OP GFS HAS NOT CHANGED MUCH FROM
THE PREVIOUS CYCLE WRT TO THE TIMING AND CONFIG OF THE ULVL FLOW
AND SFC PATTERN MON THROUGH THU. IT/S STILL A LITTLE FASTER THAN THE
12Z ECMWF AND THE 00Z GEFS SHOWS LITTLE CHANGE IN SPREAD FROM IT/S
PREVIOUS RUN. THUS...ABOVE NORMAL CONFIDENCE REMAINS WITH THE
SYNOPTIC PATTERN EVOLUTION THROUGH THE PERIOD...AND LITTLE CHANGES
WERE MADE TO THE GOING FCST.

LARGE SCALE FORCING WILL BEGIN TO INCREASE THROUGHOUT THE DAY MON AS
A STRONG H5 TROF AXIS DEEPENS INTO THE TN VALLEY. THE LLVL RESPONSE
WILL NOT SUPPORT A PREFRONTAL TROF AS MOST OF THE DEEP LEVEL ENERGY
WILL BE BREAKING DOWN THE REMNANT SFC WEDGE. THUS...SFC WINDS WILL
REMAIN GENERALLY E/LY TO SE/LY WHILE WINDS OFF THE SFC TRANSITION TO
SW/LY. A GOOD AMOUNT OF HELICITY WILL DEVELOP IN THIS ENVIRONMENT
AND DEEP LAYERED SHEAR WILL BECOME MODERATELY HIGH...HOWEVER THERE
SHOULD BE A DISTINCT LACK OF INSTABILITY AS H7 TEMPS REMAIN
RELATIVELY WARM AND KEEP A GOOD AMOUNT OF SBCIN IN PLACE THROUGHOUT
THE DAY AND OVERNIGHT PERIOD. STRONG TO SEVERE STORMS ARE NOT
PROBABLE...BUT THE HIGH LEVELS OF SHEAR COULD DEVELOP A QLCS LINE OR
TWO BY LATE EVENING ACROSS THE ERN MOST ZONES.

EXPECT THE SFC FRONT TO PUSH INTO THE NC MTNS LATE MON EVENING AND
WORK EAST OF THE CWFA BY 18Z TUE. THE UPPER DYNAMICS AND BULK SHEAR
WEAKEN AND SHIFT NORTH BY THIS TIME...SO LITTLE FANFARE IS EXPECTED
WITH THE FROPA BESIDES PERIODS OF RAIN. A STRONG CP SFC HIGH WILL
BUILD IN QUICKLY BEHIND THE FRONT AND SFC WINDS WILL BECOME N/LY
ACROSS THE MAJORITY OF THE CWFA SHORTLY AFTER SUNRISE TUE. A COOL
THETA/E AIRMASS WILL THEN WORK IN DURING THE DAY AND REMAIN THROUGH
THE PERIOD.

MAX TEMPS ON MON WILL BE ABOVE NORMAL BY A CAT OR SO AS S/LY FLOW IS
MAINTAINED AND INCREASED. MAX TEMPS FOR TUE WILL BE RIGHT AROUND
NORMAL OR A COUPLE DEGREES BELOW AS THE NEW AIRMASS WORKS IN.
WEAKENING FLOW AND CLEAR SKIES WILL ALLOW MIN TEMPS TO DROP TO
AROUND FREEZING IN THE MTNS...U30S NON/MTNS TUE NIGHT WITH SIMILAR
LOWS EXPECTED WED NIGHT. MAX TEMPS WED AND THU WILL BE HELD ABOUT
8-10 DEGREES BELOW NORMAL AS THE CP AIRMASS IS REINFORCED AS THE SFC
HIGH WEDGES DOWN THE EAST COAST.

&&

.AVIATION /18Z FRIDAY THROUGH WEDNESDAY/...
AT KCLT...HIGH PRESSURE SYSTEM WILL REMAIN OVER AREA THROUGH THE
FORECAST PERIOD PRODUCING NEARLY CLOUD FREE SKY AND GENERALLY
UNRESTRICTED VISIBILITY. POSSIBILITY OF VISIBILITY 5 MILES IN FOG
VICINITY AIRFIELD TOWARD SUNRISE SATURDAY... BUT PROBABILITY NOT
HIGH ENOUGH TO INCLUDE IN TAF AT THIS TIME.  LIGHT SOUTHWEST WIND
WILL CONTINUE DURING REMAINDER OF THE AFTERNOON... BUT SPEED SHOULD
REMAIN AROUND 5 KT. CALM EXPECTED OVERNIGHT.

ELSEWHERE...HIGH PRESSURE OVER THE SOUTHEAST WILL PRODUCE NEARLY
CLOUD FREE SKY AND GENERALLY UNRESTRICTED VISIBILITY. AREAS FOG
REDUCING VISIBILITY TO 3 TO 5 MILES POSSIBLE TOWARD SUNRISE
SATURDAY... BUT PROBABILITY TOO LOW TO INCLUDE IN FORECAST AT THIS
TIME. LIGHT NORTH WIND AT KAVL AND KHKY DURING AFTERNOON BUT
ELSEWHERE WIND WILL BE SOUTHWEST AROUND 5 KT THEN CALM ALL TERMINALS
OVERNIGHT.

OUTLOOK...VFR CONDITIONS ARE GENERALLY EXPECTED THROUGH THE WEEKEND.
