AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREENVILLE-SPARTANBURG SC
320 PM EDT WED JUN 23 2010
.SYNOPSIS...
UPPER LEVEL RIDGING WILL WEAKEN AS A WEAK COLD FRONT APPROACHES THE
AREA FROM THE NORTHWEST EARLY FRIDAY. THE FRONT WILL GRADUALLY MOVE
BACK NORTH OVER THE WEEKEND AS A BERMUDA HIGH BUILDS IN FROM THE
EAST. ANOTHER COLD FRONT WILL THEN APPROACH THE REGION EARLY NEXT
WEEK.
&&
.NEAR TERM /THROUGH THURSDAY/...
ISOLATED TO SCATTERED TSTM ACTIVITY WILL CONTINUE TO DEVELOP AND
SPREAD SE ACRS THE CWFA...INITIALLY IN THE MTNS AND PERHAPS BRIEFLY
ORGANIZED ALONG COOL POOLS/OUTFLOW BNDRIES DROPPING SWD FROM THE RNK
CWFA INTO THIS EVENING. HIGH DCAPE VALUES AGAIN THIS AFTERNOON COULD
PROMOTE ISOLATED DAMAGING WIND GUSTS. OTHERWISE FOR THE NIGHTTIME
HOURS...ANOTHER FAIR AND WARM NIGHT IS EXPECTED. UPPER RIDGING ATOP
THE CWFA TODAY WILL BREAK DOWN SOME ON THURSDAY AS SFC FRONT W/NW OF
THE MTNS SAGS TO THE SE. STORM ORGANIZATION REMAINS POSSIBLE OUT
AHEAD OF AFOREMENTIONED FRONTAL BAND...BUT ISOLATED TO SCATTERED
DISORGANIZED STORMS ARE EXPECTED ONCE AGAIN ACRS THE CWFA THURSDAY
AFTERNOON WITHIN THE MODERATELY UNSTABLE YET CONTINUED WEAKLY
SHEARED ENVIRONMENT. MAX TEMPS CLOSE TO PERSISTENCE THURSDAY
AFTERNOON...WITH MID TO UPPER 90S IN THE PIEDMONT AND HEAT INDEX
VALUES IN THE LOWER 100S. EXPECTED THURSDAY MAXES TO BE THE 13TH
CONSECUTIVE 90+ DAY FOR GSP/CLT.
&&
.SHORT TERM /THURSDAY NIGHT THROUGH SATURDAY NIGHT/...
AS OF 215 PM WEDNESDAY...THE UPPER RIDGE IS STILL EXPECTED TO WEAKEN
SOMEWHAT LATE IN THE WEEK BUT THE TRACK OF SHORT WAVES SHOULD REMAIN
WELL TO THE NORTH. THE NAM AND ECMWF BOTH BRING A WEAK SURFACE
BOUNDARY SOUTH THURSDAY NIGHT AND ESSENTIALLY STALL IT ACROSS THE
SOUTHERN PART OF THE FCST AREA ON FRIDAY. WITHOUT ANY SIGNIFICANT
UPPER TROFFING DEVELOPING ON THE E COAST...THERE IS SOME CONCERN
THAT THE BOUNDARY WILL NOT ACTUALLY MAKE IT MUCH PAST THE MTNS. EVEN
IF IT DOES...WE DO NOT EXPECT MUCH IMPROVEMENT IN LOWERING HIGH
TEMPS SO OUR STREAK OF 90+ SHOULD CONTINUE. THE PROXIMITY OF AN OLD
SURFACE BOUNDARY SHOULD PROVIDE A BIT MORE IN THE WAY OF LOW LEVEL
CONVERGENCE WHICH SHOULD ENHANCE OUR THUNDERSTORM CHANCES ON FRIDAY.
THROUGH ALL THIS...THE BERMUDA HIGH SHOULD REMAIN INTACT WHICH
SHOULD MAINTAIN OUR SUPPLY OF LOW LEVEL MOISTURE AND KEEP BUOYANCY
HIGH IN THE AFTERNOON. SO...SCATTERED THUNDERSTORMS SHOULD DIE OFF
IN THE LATE EVENING AND THEN REDEVELOP SATURDAY AFTERNOON.
&&
.LONG TERM /SUNDAY THROUGH WEDNESDAY/...
AS OF 3 PM WEDNESDAY...CONFIDENCE IN THE MEDIUM RANGE GRADUALLY
DIMINISHES THROUGH THE EARLY TO MIDDLE PART OF NEXT WEEK AS THE
POSSIBILITY OF A TROPICAL LOW IN THE GULF OF MEXICO LOOMS LARGER.
THE OPERATIONAL GFS WAS COMPLETELY DISREGARDED AS IT ARRIVED LATE
AND FAILED TO PICK UP ON THE LOW IN THE GULF EARLY NEXT WEEK. EITHER
WAY...THERE IS SOME CONFIDENCE THAT THE UPPER PATTERN WILL AMPLIFY
EARLY NEXT WEEK. AFTER ONE MORE DAY OF DIURNALLY MODULATED
THUNDERSTORMS ON SUNDAY/SUNDAY NIGHT...THE DEVELOPMENT OF AN UPPER
TROF ON THE EAST COAST SHOULD DRIVE A COLD FRONT DOWN ACROSS THE
FORECAST AREA MONDAY NIGHT/TUESDAY MORNING. FOLLOWING HPC TIMING...
THIS GIVES THE BEST CHANCE FOR THUNDERSTORMS ON MONDAY
AFTERNOON/EVE. HIGH PRESSURE SHOULD BUILD IN FROM THE NORTH TUESDAY
AND WEDNESDAY AND BREAK OUR STRING OF 90+ HIGH TEMPS E OF THE MTNS.
OF COURSE...THE EVENTUAL AND UNCERTAIN FATE OF ANY TROPICAL
SITUATION COULD COMPLETELY THROW THIS INTO DISARRAY...SO EXPECT SOME
POTENTIALLY BIG CHANGES TO THE FCST.
&&
.AVIATION /19Z WEDNESDAY THROUGH MONDAY/...
AT KCLT...STILL TOO LOW OF AN UNCERTAINTY LVL THAT ANY TSTM WILL NEAR
THE TERMINAL LATER THIS AFTERNOON...AND WILL AMEND IF NECESSARY AS
THE DAY WEARS ON. WITH MIN TEMPS FCST TO BE SVRL CATEGORIES ABOVE
CROSSOVER TEMPERATURE...NO BR IS EXPECTED AGAIN THURSDAY MORNING.
ELSEWHERE...BASED ON EXPECTED TSTM CVRG...BEST CHANCES FOR A TSTM
WILL BE AT KAVL...BUT JUST LIKE YSTDY AFTN/EVE...JUST ABOUT ANY
TERMINAL STANDS A SLIGHT CHANCE. ANY LATE NIGHT/EARLY AM BR CHANCES
WILL CONTINUE TO BE LIMITED TO KAVL.
OUTLOOK...GENERALLY VFR WEATHER EXCEPT CEILING AND VISIBILITY
RESTRICTIONS IN SCATTERED THUNDERSTORMS ESPECIALLY THURSDAY AND
FRIDAY. MORNING VISIBILITY RESTRICTIONS IN FOG IN MOUNTAIN VALLEYS
AND WHERE RAIN FALLS.
