AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREENVILLE-SPARTANBURG SC
253 PM EDT SUN MAY 11 2008
.SYNOPSIS...
A DEEP LOW PRESSURE SYSTEM WILL BE NEAR THE NEW JERSEY COAST TONIGHT
AS IT DRAGS A COLD FRONT TOWARD THE CAROLINA COAST. DRY HIGH
PRESSURE WILL BUILD IN FROM THE WEST MONDAY AND TUESDAY. ANOTHER
COLD FRONT WILL APPROACH FROM THE WEST THURSDAY BEFORE STALLING IN
THE VICINITY AND KEEPING CONDITIONS UNSETTLED INTO NEXT WEEKEND.
&&
.NEAR TERM /UNTIL 6 AM MONDAY MORNING/...
LINE OF STRONG TO SEVERE STORMS SHOULD EXIT THE CWFA QUICKLY THIS
AFTERNOON. HOWEVER...ADDITIONAL SCATTERED TO ISOLATED SHOWERS AND
STORMS WILL MOVE ACROSS THE AREA LATE THIS AFTERNOON WITH THE
FRONTAL BOUNDARY TO OUR WEST MOVES IN. CANNOT COMPLETELY RULE OUT A
SEVERE STORM WITH THE SECOND LINE...BUT CHC IS MINIMAL. PRECIP WILL
END OUTSIDE OF THE MTNS BY THIS EVENING. HOWEVER...LOW LEVEL
MOISTURE WRAPS BACK INTO THE MTNS AND SHOWERS WILL REDEVELOP THERE
AS STRONG UPSLOPE FLOW AND SHORT WAVE ENERGY MOVE IN.
WINDS WILL CONTINUE TO PICK UP AND BECOME GUSTY ACROSS THE WESTERN
SECTIONS AS THE FRONT MOVES THROUGH. THESE WINDS WILL CONTINUE INTO
THE EVENING BEFORE DIMINISHING OUTSIDE OF THE MTNS. THE WINDS
ACTUALLY INCREASE ACROSS THE MTNS OVERNIGHT WITH GUSTS POSSIBLY 50
KTS OR HIGHER. GIVEN THESE WINDS...CURRENT WIND ADVISORY/HIGH WIND
WARNINGS LOOK GOOD. THESE WILL REMAIN IN PLACE OVERNIGHT.
TEMPERATURES OVER SOME RIDGE TOPS WILL FALL INTO THE MID
30S..ALTHOUGH VALLEY LOCATIONS WILL REMAIN IN THE LOW TO MID 40S.
WITH THE EXPECTED WINDS...FROST SHOULD NOT BE A PROBLEM. CANNOT RULE
OUT SOME SNOWFLAKES MIXING IN WITH THE RAIN ABOVE 5000 FT...BUT NO
TRAVEL PROBLEMS EXPECTED. OUTSIDE OF THE MTNS...TEMPS WILL FALL INTO
THE UPPER 40S TO LOWER 50S.
&&
.SHORT TERM /6 AM MONDAY MORNING THROUGH WEDNESDAY NIGHT/...
AS OF 230 PM SUNDAY...STILL EXPECTING A PERIOD OF BLUSTERY
CONDITIONS ON MONDAY AS THE CWFA LINGERS WITHIN THE CIRCULATION OF
DEPARTING LOW PRESSURE. DOWNSLOPE DRYING IS ON TAP FOR AREAS
EAST OF THE BLUE RIDGE...WITH SOME WRAP-AROUND/UPSLOPE SHOWERS
PROBABLE FOR THE NC MTNS...ESPECIALLY THE WESTERN SLOPES. GOING WIND
ADVISORY AND WARNINGS LOOK TO BE ON TRACK AND WILL LIKELY NEED LAKE
WIND ADVISORIES FOR THOSE AREAS OUTSIDE OF EXPECTED WIND
WARNING/ADVISORY. WITH SFC RIDGING BUILDING EAST INTO THE CWFA
MONDAY NIGHT...WINDS WILL BECOME LIGHT. DEEP DRYING WITHIN
NW FLOW ALOFT WILL PROMOTE MOSTLY CLEAR SKIES ALLOWING TEMPERATURES
TO FALL TO BELOW NORMAL LEVELS. DEEP LAYERED RIDGING TO PROMOTE
SUNSHINE AND SEASONABLY MILD CONDITIONS FOR TUESDAY. HIGHER LEVEL
MOISTURE WILL TOP UPPER RIDGING TUESDAY NIGHT LEADING TO SOME DEGREE
OF INCREASING CLOUDS. FRONTAL BNDRY PROGGED TO SAG SOUTHEAST TOWARD
THE REGION ON WEDNESDAY...AND WILL MAINTAIN GOING CHANCE POPS.
&&
.LONG TERM /THURSDAY THROUGH SATURDAY/...
AS OF 215 PM SUNDAY...AS THE FRONT CROSSES THE AREA FROM THE
NORTHWEST EARLY THURSDAY...IT IS FORECAST TO STALL OUT VERY NEAR OR
JUST TO THE SOUTH OF OUR FORECAST AREA. LOW PRESSURE WILL FORM NEAR
TEXAS AND RIDE ALONG THE FRONT SPREADING MOISTURE INTO THE CAROLINAS
FROM THURSDAY INTO FRIDAY. IT APPEARS THAT INSTABILITY WILL
GENERALLY BE LIMITED TO LOCATIONS IN THE PIEDMONT AND FOOTHILLS AS
THE LOW APPROACHES FROM THE SOUTHWEST. THE ECMWF IS CONSIDERED THE
PREFERRED MODEL AND IT TAKES THE LOW OFF THE MID ATLANTIC COAST
FRIDAY NIGHT AND EARLY SATURDAY. A DEEP UPPER TROUGH FOLLOWS BEHIND
THE LOW THROUGH THE WEEKEND AS IT MOVES SOUTHEAST FROM THE GREAT
LAKES. MOISTURE WILL ATTEND THE UPPER TROUGH EXTENDING SOUTH ALONG
THE APPALACHIANS. NOT SURE HOW FAR SOUTH THIS WILL EXTEND...BUT
WANTED TO INCLUDE POPS FOR THE NC MOUNTAINS AND TAPPER IT OFF AT THE
END OF THE WEEKEND. TEMPERATURES WILL BE BELOW NORMAL AS THE AXIS
OF THIS TROUGH PASSES.
&&
.AVIATION /19Z SUNDAY THROUGH FRIDAY/...
SHOWERS AND ISOLATED TS SHOULD MOVE EAST OF THE AREA QUICKLY THIS
AFTERNOON. LOW CIGS WILL CONTINUE UNTIL THE DRY SLOT SEEN TO OUR
WEST MOVES IN. WINDS WILL PICK UP HOWEVER AND BECOME GUSTY THRU THE
EVENING. WINDS DIMINISH OVERNIGHT EXCEPT OVER KAVL WHERE GUSTS
CONTINUE AND WILL ACTUALLY STRENGTHEN. LOW LEVEL MOISTURE WRAPS BACK
INTO THE AREA WITH MVFR CIGS REDEVELOPING AT KAVL...WITH LOW VFR
CIGS POSSIBLE ELSEWHERE. THESE LOW CIGS WILL CONTINUE AT KAVL MONDAY
MORNING...BUT WILL LIFT ELSEWHERE. WINDS BECOME GUSTY ONCE AGAIN
OUTSIDE OF THE MTNS AS MIXING BEGINS.
OUTLOOK...WINDS REMAIN VERY GUSTY THROUGH MONDAY AFTERNOON WITH
DIMINISHING CLOUDS. CONDITIONS WILL STEADILY IMPROVE TUESDAY...WITH
SLACKENING WINDS AND VFR CONDITIONS. DIURNAL THUNDERSTORMS WILL
RETURN MID TO LATE WEEK AS A COLD FRONT MOVES IN FROM THE WEST AND
STALLS NEAR THE SOUTHERN APPALACHIANS.
