AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREENVILLE-SPARTANBURG SC
310 PM EDT SAT AUG 25 2007
.SYNOPSIS...
AN UPPER LEVEL DISTURBANCE AND ASSOCIATED COLD FRONT MOVE IN FROM
THE NORTHWEST ON SUNDAY...BECOME STATIONARY...AND SLOWLY DISSIPATE
AS THE UPPER RIDGE BUILDS BACK OVER OUR REGION DURING THE FIRST HALF
OF THE WEEK.
&&
.NEAR TERM /THROUGH SUNDAY/...
EXPECT AFTN AND EVENING CONVECTION TO DISSIPATE WITH LOSS OF DAYTIME
HEATING. SOME STORMS WILL BE SEVERE...WITH DAMAGING WINDS BEING THE
GREATEST THREAT. THE GFS HAS QPF OVERNIGHT ACROSS THE MTNS...WITH
THE NAM GOING DRY BY 6Z SUNDAY. THE DIFFERENCES IN THE TIMING OF A
WEAK VORT MAX AND PASSAGE OF WIND SHIFT/PRE-FRONTAL TROUGH ACROSS
THE MTNS IS RATHER SUBTLE (ABOUT 6 HOURS). BOTH HAVE SOME
INSTABILITY WELL INTO THE OVERNIGHT HOURS. SO GIVEN THE POTENTIAL
FOR SOME LIFT ACROSS THE MTNS...ESPECIALLY THE WESTERN SLOPES OF THE
GREAT SMOKIES AND CENTRAL NC MTNS...KEPT SLIGHT CHC POP FOR THUNDER
OVERNIGHT. COLD FRONT APPROACHES AND IS PROGGED TO BE WITHIN THE
CWFA BY 18Z SUNDAY. AGAIN...PLENTY OF INSTABILITY IN PLACE. SO WENT
WITH SOLID CHANCE EVERYWHERE (40-50%) FOR SUNDAY AFTN. THE POTENTIAL
FOR PULSE SEVERE THUNDERSTORMS SHOULD BE A BIT HIGHER SUNDAY WITH
INCREASED COVERAGE OF THUNDERSTORMS EXPECTED. WITH MORE CLOUD COVER
AND LOWER HEIGHTS ALOFT...MAX TEMPS WILL BE IN THE LOWER 90S
PIEDMONT...80S MTN VALLEYS.
&&
.SHORT TERM /SUNDAY NIGHT THROUGH TUESDAY/...
SHORT WAVE TROF MOVES OUT OF THE AREA SUNDAY NIGHT THEN WEAK UPPER
RIDGING RETURNS FOR MONDAY AND TUESDAY. NAM APPEARED TO BE THE
OUTLIER WITH THE GULF COAST LOW SHEARING OUR AND MOVING NORTHEAST
INTO OUR AREA. OTHERWISE...ITS PATTERN IS SIMILAR TO THE GFS.
FRONTAL SYSTEM MOVES TO OUR SOUTH SUNDAY NIGHT AND STALLS THERE FOR
MONDAY. SCATTERED CONVECTION SUNDAY EVENING BECOMES MORE ISOLATED
AFTER MIDNIGHT...BUT COULD LINGER TOWARD MORNING CLOSER TO THE FRONT.
ABOVE NORMAL LOWS EXPECTED SUNDAY NIGHT. MODELS HAVE DECENT LOW
LEVEL MOISTURE AND CONVERGENCE ALONG WITH INSTABILITY MONDAY.
HOWEVER...THE GFS KEEPS CONVECTION MAINLY OVER THE SOUTH WHILE THE
NAM HAS IT OVER THE MTNS AND SOUTHEAST OF THE CWFA. WITH LITTLE IN
THE WAY OF SYNOPTIC FORCING...EXPECT ISOLATED DIURNAL CONVECTION
WEST OF THE BLUE RIDGE WITH SCT CONVECTION ALONG AND EAST OF IT.
ABOVE NORMAL HIGHS MONDAY BACK INTO THE LOWER 90S OUTSIDE OF THE
MTNS AND NEAR 90 MTN VALLEYS.
EXPECT CONVECTION TO BECOME ISOLATED MONDAY NIGHT AND END BY
MIDNIGHT WITH LOSS OF HEATING AND LACK OF SYNOPTIC FORCING. LOWS NEAR
NORMAL NC FOOTHILLS/PIEDMONT...BUT A FEW DEGREES ABOVE NORMAL
ELSEWHERE.
FRONT WASHES OUT ON TUESDAY...WITH SOME SORT OF COASTAL LOW FORMING
OFF CAPE HATTERAS. LESS IN THE WAY OF LOW LEVEL CONVERGENCE BUT
MOISTURE STILL DECENT. ATMOSPHERE REMAINS UNSTABLE...BUT MODELS
STILL CANNOT QUITE AGREE ON WHICH LOCATION HAS THE BEST CHC OF
CONVECTION. USING MODEL BLEND...HAVE SCATTERED CONVECTION ALONG AND
SOUTH OF I-85 AND ISOLATED NORTH. HIGHS A DEGREE OR TWO COOLER THAN
MONDAY...BUT STILL SEVERAL DEGREES ABOVE NORMAL.
&&
.LONG TERM /TUESDAY NIGHT THROUGH SATURDAY/...
UPPER RIDGE WEAKENS AND RETROGRADES WEDNESDAY AND IS REPLACED BY A
TROF THURSDAY. THIS TROF HOLDS ON THROUGH SATURDAY. SFC HIGH
PRESSURE MOVES IN WEDNESDAY. COULD SEE SOME ISOLATED DIURNAL
CONVECTION OVER THE MTNS...BUT MOISTURE AND INSTABILITY LIMITED.
ABOVE NORMAL TEMPERATURES ONCE AGAIN TUE NITE AND WEDNESDAY. FRONTAL
SYSTEM MOVES IN THURSDAY AND REMAINS STALLED JUST TO OUR SOUTH
FRIDAY AND SATURDAY. ISOLATED DIURNAL CONVECTION THURSDAY WITH ABOVE
NORMAL TEMPS...BUT MAYBE A DEGREE OR TWO COOLER THAN WEDNESDAY. THEN
THE MUCH ANTICIPATED AND HOPED FOR PATTERN CHANGE STILL FORECAST
FRIDAY AND SATURDAY. IF THIS OCCURS...THEN WE SHOULD SEE SCATTERED
CONVECTION WITH NEAR NORMAL LOWS AND BELOW NORMAL HIGHS.
&&
.AVIATION /19Z SATURDAY THROUGH THURSDAY/...
SCT SHWRS/TSTMS...HAVE DEVELOPED OVER THE PAST COUPLE OF HOURS OVER
THE MTNS W OF KAVL. EXPECT SIMILAR COVERAGE AS YESTERDAY (MTNS AND
WRN PIEDMONT (KAND/KGMU/KGSP)...WITH ISOLD COVERAGE AROUND KCLT.
CONTINUED CB CLOUDS ALL AREAS EXCEPT KCLT...WITH VCTS AT KAVL.
COLD FRONT APPROACHES THE REGION SUNDAY SO EXPECT LARGER COVERAGE OF
AFTN-EVE CONVECTION SUNDAY INTO THE FIRST PART OF NEXT WEEK. PATCHY
MORNING FOG WILL ALSO BE POSSIBLE EACH DAY...ESPECIALLY MTN VALLEYS.
&&
.GSP WATCHES/WARNINGS/ADVISORIES...
GA...NONE.
NC...AIR QUALITY ACTION DAY UNTIL 9 PM EDT THIS EVENING FOR NCZ036-
037-057-069>072-082.
