AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREENVILLE-SPARTANBURG SC
259 AM EDT FRI MAY 18 2007

.SYNOPSIS...
AN UPPER LOW OVER THE MID-ATLANTIC STATES WILL BRING COOLER
TEMPERATURES TODAY AND SATURDAY. HIGH PRESSURE WILL THEN BUILD INTO
THE REGION SUNDAY...BRINGING GENERALLY FAIR WEATHER THROUGH THE
MIDDLE PART OF THE WEEK...THOUGH AN ISOLATED THUNDERSTORM IS
POSSIBLE IN THE MOUNTAINS MONDAY.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
THE LINE OF SHOWERS ASSOCIATED WITH A VORT MAX ROTATING AROUND THE
SOUTHERN PERIPHERY OF THE OHIO VALLEY UPPER LOW HAS MOVED NORTHEAST
OF THE REGION. THIS SHOULD ESSENTIALLY SPELL AN END TO THE CHANCES
FOR PRECIPITATION ACROSS THE CWFA FOR A FEW DAYS. THE BETTER
MOISTURE AND INSTABILITY WILL BE EAST OF THE REGION TODAY...WHILE
THE BEST FORCING WILL BE TO OUR NORTH...SO WE ARE NOT EXPECTING
DIURNAL DEVELOPMENT OF DEEP CONVECTION TODAY. IN FACT...WE AREN/T
EXPECTING MUCH IN THE WAY OF CLOUD COVER DURING THE DAYLIGHT
HOURS...EXCEPT FOR SOME AFTERNOON CU ACROSS THE EASTERN AND NORTHERN
ZONES.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH MONDAY/...
AS AN UPPER LOW SPINS OVER THE DELMARVA OVERNIGHT...LLVL THICKNESSES
WILL REMAIN QUITE COOL OVER THE REGION...AND H8 TEMPS WILL FALL TO
AROUND +4 DEG C. DEWPOINTS WILL ALSO BE QUITE LOW AND SKIES
CLEAR...WHICH WILL OPTIMIZE RADIATIONAL COOLING. HOWEVER...THERE
WILL STILL BE ENOUGH OF A GRADIENT ACROSS THE REGION TO KEEP NW TO
SE ORIENTED VALLEYS MIXED MUCH OF THE NIGHT. THIS MEANS THAT A GOOD
BIT OF THE ASHEVILLE TO HENDERSONVILLE AREA MAY NOT SEE FROST. EVEN
IF MANY OF THE METRO AREAS STAY NEAR 40...MANY OF THE MORE SHELTERED
VALLEYS SHOULD FALL WELL INTO THE 30S. THE PATH OF LEAST REGRET AT
THIS POINT IS TO HOIST A FROST ADVISORY FOR THE NC MTNS...WITH THE
EXCEPTION OF THE EASTERN MTNS WHERE DOWNSLOPE WILL KEEPS MINS
SOLIDLY IN THE 40S.

ON SATURDAY SKIES WILL BE SUNNY AND MAX TEMPS WILL REBOUND TO AROUND
SEASONABLE LEVELS AS H8 TEMPS WARM RAPIDLY DURING THE DAY. OTHER
THAN FIRE WEATHER ISSUES...IT WILL BE A BEAUTIFUL DAY. THE SAME
HOLDS FOR SUNDAY. FLOW WILL TURN A LITTLE MORE OUT OF THE WEST AS
HEIGHTS FALL OVER THE MIDWEST. THIS WILL ADD A COUPLE DEGREES OF
DOWNSLOPE WARMING TO THE MIX...AND TEMPS SHOULD RISE WILL INTO THE
80S IN THE FOOTHILLS AND PIEDMONT WITH SUNNY SKIES.

ON MONDAY THE TAIL END OF A COLD FRONT WASHES OUT OVER THE REGION
AS HEIGHTS RISE ALOFT. WITH A LITTLE UPSLOPE FLOW AND BETTER DEEP
LAYER RH/S...THERE IS A SLIGHT CHANCE OF CONVECTION IN THE AFTERNOON
IN THE NC ZONES. I/LL CARRY SOMETHING IN THE NEIGHBORHOOD OF 20
PERCENT AS THE FORCING LOOKS TOO WEAK FOR ANYTHING MORE WIDESPREAD.

&&

.LONG TERM /MONDAY NIGHT THROUGH THURSDAY/...
THINKING IN THE 4-7 DAY TIME FRAME HASN/T CHANGED MUCH WITH THIS
PACKAGE. DEEP LAYER RIDGING WILL AFFECT THE REGION THROUGH MOST OF
THE EXTENDED PERIOD...WITH A COLD FRONT APPROACHING BY THURSDAY. THE
LOW LEVEL FLOW...PER THE GFS...WILL MAINTAIN AN E TO SE ORIENTATION
DURING THIS TIME. THIS WILL HOLD DOWN MAX TEMPS TO AN EXTENT...AND
WILL PROBABLY AID IN THE DEVELOPMENT OF SCT CONVECTION TUE. ATTM WE
DON/T HAVE CONVECTION IN THE GRIDS TUE...WHICH IS SOMETHING THAT THE
DAY SHIFT MAY HAVE TO TWEAK. BY WED THE GFS DRIES THE AIRMASS OUT TO
THE POINT WHERE THERE MAY NOT EVEN BE ANY DIURNALLY DRIVEN
CONVECTION. POPS INCREASE ON THU...WHICH STILL SEEMS LIKE A GOOD
CALL...THOUGH THERE IS SOME HINT THAT THE FRONT MAY APPROACH A
LITTLE MORE SLOWLY.

&&

.AVIATION /07Z FRIDAY THROUGH TUESDAY/...
SOME MID-LEVEL CLOUDINESS LINGERS ACROSS THE REGION EARLY THIS
MORNING...BUT THIS SHOULD BEGIN TO DISSIPATE AROUND SUNRISE. THIS IS
EXPECTED TO GIVE WAY TO SKC CONDITIONS FOR MUCH OF THE DAYLIGHT
HOURS. A FEW CU MAY BE SEEN AT KCLT DURING THE AFTERNOON...BUT ANY
DEEP CONVECTION SHOULD BE CONFINED TO LOCATIONS WELL EAST OF THE
AREA.

DRY HIGH PRES WILL BUILD OVER THE AREA THIS WEEKEND. A DRY BACKDOOR
COLD FRONT WILL APPROACH THE AREA EARLY NEXT WEEK. NO WIDESPREAD CIG
OR VSBY RESTRICTIONS ARE EXPECTED.

&&

.FIRE WEATHER...
RED FLAG WARNING WILL CONTINUE FOR NE GA TODAY AS RH/S SHOULD DROP
TO 25 PERCENT OR LESS FOR THE REQUISITE 4 HR PERIOD. ON SATURDAY A
STRONG SUBSIDENCE INVERSION SHOULD MIX MUCH DRIER AIR DOWN ACROSS
THE MOUNTAINS...AND QUITE POSSIBLY INTO THE FOOTHILLS. I/VE GONE
QUITE A BIT DRIER THAN MOS...BUT STILL NOT AS LOW AS THE BUFKIT
SOUNDINGS WOULD IMPLY WITH FULL MIXING. THIS IS IMPORTANT FOR THE NC
LAND MANAGEMENT FOLKS TO NOTE. RH/S MAY VERY WELL MIX INTO THE TEENS
SATURDAY AFTERNOON IN THE VALLEYS...AND EVEN AT HIGHER ELEVATIONS.
NORTHWEST WINDS MAY GUSTS UP TO 25 MPH FROM THE FRENCH BROAD VALLEY
NORTHWARD...WITH GUSTS APPROACHING 30 MPH OVER THE NORTHERN
MOUNTAINS. IF THESE CONDITIONS DEVELOP...THEN THERE COULD BE
SIGNIFICANT FIRE WX ISSUES DEPENDING UPON HOW MUCH GREEN-UP THERE
HAS BEEN IN THE MOUNTAINS. RH RECOVERY COULD BE LIMITED SAT NIGHT
WITH ANOTHER DRY DAY ON SUNDAY.

&&

.GSP WATCHES/WARNINGS/ADVISORIES...
GA...RED FLAG WARNING FROM NOON TODAY TO 8 PM EDT THIS EVENING FOR
     GAZ010-017-018-026-028-029.
