AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREENVILLE-SPARTANBURG SC
245 AM EDT FRI OCT 31 2008
.SYNOPSIS...
DRY HIGH PRESSURE WILL DOMINATE THE REGION FRIDAY THROUGH SATURDAY.
A WEAK COLD FRONT WILL MOVE INTO THE AREA FROM THE NORTH ON
SUNDAY...BUT IT WILL BE ACCOMPANIED BY LITTLE OR NO MOISTURE. LOW
PRESSURE WILL DEVELOP OFF THE SOUTHEAST COASTLINE EARLY NEXT WEEK
AND SPREAD LIMITED MOISTURE INLAND THROUGH WEDNESDAY. A STRONG COLD
FRONT WILL THEN APPROACH FROM THE WEST LATE IN THE WEEK.
&&
.NEAR TERM /THROUGH TONIGHT/...
A LOW AMPLITUDE UPPER RIDGE WILL MOVE ACROSS THE AREA TODAY AND
TONIGHT...WHILE DRY HIGH PRESSURE LINGERS AT THE SURFACE. WITH
LITTLE OR NO WARM ADVECTION IN A LIGHT SOUTHERLY WIND...MAXIMUM
TEMPERATURES ARE EXPECTED TO BE NEAR THE COOL SIDE OF GUIDANCE...AND
ONLY A COUPLE OF DEGREES WARMER THAN YESTERDAY. RADIATIONAL COOLING
WILL TAKE MINIMUM TEMPERATURES INTO THE MID TO UPPER 30S TONIGHT.
&&
.SHORT TERM /SATURDAY THROUGH SUNDAY NIGHT/...
AS OF 230 AM FRIDAY...THE SHORT RANGE PERIOD WILL BEGIN WITH A
CUTOFF UPPER LOW DRIFTING SOUTHWARD ACROSS THE CENTRAL GULF COAST ON
SATURDAY. MEANWHILE...A BACKDOOR COLD FRONT WILL DROP SOUTH THROUGH
THE MID ATLANTIC SATURDAY AND MOVE INTO THE NORTHERN TIER OF THE
FORECAST AREA ON SUNDAY. AN ATLANTIC MOISTURE CONVERGENCE ZONE WILL
DEVELOP BETWEEN THESE FEATURES OVER THE WEEKEND...BUT WITH ANY
ASSOCIATED PRECIPITATION REMAINING SOUTH OF THE FORECAST AREA. MODEL
CONSENSUS SUGGESTS THAT SOUTHERN LOW PRES SYSTEM WILL THEN SLOWLY
FILL AS IT MOVES INTO NORTHERN FLORIDA LATE IN THE WEEKEND.
A DRY FORECAST WILL BE FEATURED THROUGH THE WEEKEND. TEMPERATURES
SHOULD BE AT LEAST TWO CATEGORIES ABOVE CLIMATE NORMS ON SATURDAY
WITH WARMING THICKNESSES AHEAD OF THE BACKDOOR FRONT. SLIGHT COOLING
IS EXPECTED ON SUNDAY...BUT WITH TEMPS REMAINING ABOVE NORMAL.
&&
.LONG TERM /MONDAY THROUGH THURSDAY/...
AS OF 230 AM FRIDAY...THE PERSISTENT LOW LEVEL EASTERLY FETCH
BETWEEN THE SOUTHEAST LOW PRES SYSTEM AND A STRONG MID ATLANTIC
RIDGE OF HIGH PRESSURE WILL ALLOW LOW LEVEL MOISTURE TO INCREASE
ACROSS THE AREA MON TO WED. MODEL DIFFERENCES PERSIST WITH THE
HANDLING OF THE SFC LOW OFF THE SOUTHEAST COAST...WITH THE GFS STILL
CLINGING TO A DEEPER LOW NEARER THE COAST TUESDAY THROUGH WEDNESDAY.
THE LATEST GFS ENSEMBLE SOLUTION...HOWEVER..MORE CLOSELY RESEMBLES
THE 12Z THU ECMWF. THIS SHOULD PRECLUDE ANY SLIGHT CHANCES FOR RAIN
SHOWERS TO JUST THE EXTREME EASTERN PIEDMONT SECTIONS AROUND MID
WEEK. RIDGING SHOULD REASSERT ITSELF BY THURSDAY AS THE COASTAL LOW
SLOWLY DEPARTS...WITH A VIGOROUS COLD FRONT APPROACHING FROM THE
WEST VERY LATE IN THE PERIOD.
&&
.AVIATION /07Z FRIDAY THROUGH TUESDAY/...
VFR EXPECTED DURING THIS TAF PERIOD. ALTHOUGH SOME DEW POINT
DEPRESSIONS ARE RATHER LOW...GUIDANCE CARRIED NO FOG AT ANY TAF
SITES THIS MORNING. CALM WINDS WILL GIVE WAY TO LIGHT SOUTH WINDS
BY LATE MORNING. WINDS WILL BECOME CALM OR LIGHT AND VARIABLE BY
LATE FRIDAY EVENING.
OUTLOOK...VFR CONDITIONS ARE EXPECTED TO CONTINUE THROUGH MONDAY.
MOISTURE ASSOCIATED WITH A COASTAL LOW MAY JUST REACH AS FAR WEST AS
KCLT ON TUE...BUT AT THIS POINT SCATTERED LOW CLOUDS LOOK LIKE THE
GREATEST IMPACT.
&&
.FIRE WEATHER...
THE COMBINATION OF HIGH TEMPERATURES IN THE UPPER 60S...DEWPOINTS IN
THE UPPER 20S TO LOWER 30S...AND FUEL MOISTURES BELOW 10 PERCENT
THIS AFTERNOON WILL CREATE CRITICAL FIRE WEATHER CONDITIONS ACROSS
NORTHEAST GEORGIA. WITH RH VALUES DIPPING BELOW 25 PERCENT FOR
SEVERAL HOURS...A RED FLAG WARNING WILL BE POSTED.
