AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREENVILLE-SPARTANBURG SC
446 PM EDT THU JUN 9 2011

.SYNOPSIS...
AN UPPER LEVEL RIDGING PATTERN WILL CONTINUE TO PERSIST ACROSS THE
AREA. THE RIDGING WILL SHIFT EASTWARD OVER THE ATLANTIC WITH THE
APPROACH OF A WEAK COLD FRONT OVER THE WEEKEND. THE FRONT WILL MOVE
SOUTH OF THE AREA FOR MUCH OF THE FIRST HALF OF NEXT WEEK...LIKELY
PROVIDING MORE SEASONABLE TEMPERATURES.

&&

.NEAR TERM /THROUGH FRIDAY/...
2045 UTC UPDATE...POPS HAVE BEEN INCREASED NEAR KGMU...PER THE
LATEST RADAR TRENDS. QPF HAS BEEN INCREASE THERE AS WELL.

PREVIOUS DISCUSSION...CONVECTION SHOULD CONTINUE TO EXPAND ACROSS
THE MTNS AND ADJACENT FOOTHILLS WILL THE DEVELOPMENT OF COOL POOLS
AND WEAK UPSLOPE FLOW. IN ADDITION...AN OUTFLOW BOUNDARY...OVER NE
TN AT 18Z...SHOULD REACH THE SOUTHERN APPALACHIANS LATE THIS
AFTERNOON. EAST OF THE MTNS...A LEE TROF SHOULD INCREASE LLVL
CONVERGENCE AND RESULT IN SCT CONVECTION DURING THE LATE AFTERNOON
AND EVENING. I HAVE INCREASED POPS ACROSS THE MTNS AND WESTERN
FOOTHILLS TO LIKELY TO LOW CATE...WITH LATE AFTERNOON CHC EAST OF
THE MTNS. CONDITIONS SHOULD STABILIZE STEADILY AROUND
SUNSET...CONVECTION SHOULD ASHE OUT AN HOUR OR TWO AFTER SUNSET.

CAPE VALUES THIS AFTERNOON SHOULD RANGE BETWEEN 2500-3500 J/KG. THE
FZL MAY REMAIN NEAR 14 KFT...YIELDING A CORE HEIGHT AROUND 26 KFT.
DCAPE VALUES WILL RANGE BETWEEN 1000-1400 J/KG. SEVERAL STORMS MAY
PRODUCE SEVERE WEATHER. IN ADDITION...SLOW STORM MOTIONS COULD YIELD
AREAS OF EXCESSIVE RAINFALL AND FLASH FLOOD. WE WILL CONTINUE TO
MENTION BOTH THE SVR THREAT AND FLOODING THREAT IN THE HWO.

CLEARING DEBRIS CLOUDS AND LIGHT WINDS EXPECTED TONIGHT. FOG WILL
LIKELY DEVELOP WITHIN THE MTNS VALLEYS AND AROUND AREAS OF RAINFALL
THIS AFTERNOON AND EVENING. LOW TEMPERATURES WILL LIKELY RANGE FROM
THE L60S ACROSS THE MTNS TO U60S EAST.

FRIDAY...CONDITIONS WILL REMAIN VERY SIMILAR TO TODAY. HIGH
TEMPERATURES SHOULD RANGE FROM THE U80S ACROSS THE MTNS TO LOW TO
MID 90S EAST. DEWPOINTS MAY RANGE 1 TO 3 DEGREE WARMER THAN TODAY.
CAPE VALUES SHOULD RANGE BETWEEN 1500 TO 2500 J/KG WITH MINIMAL CIN.
WEAK UPSLOPE FLOW AND RIDGETOP CONVERGENCE SHOULD TRIGGER TSRA
ACROSS THE MTNS BETWEEN 18 TO 20Z. CONVECTION IS EXPECTED TO DRIFT
EAST OVER THE FOOTHILLS DURING THE LATE AFTERNOON AND EARLY EVENING.
THE ATMOSPHERE SHOULD BEGIN TO STABILIZE BEFORE THE CONVECTION
PUSHES EAST OF THE I-85 CORRIDOR. I WILL ADVERTISE CHC POPS ACROSS
THE MTNS AND FOOTHILLS AND SCHC EAST. AS THE CASE THE PAST SEVERAL
DAYS...A FEW OF THESE STORMS COULD PRODUCE SEVERE WEATHER OR
EXCESSIVE RAINFALL.

&&

.SHORT TERM /FRIDAY NIGHT THROUGH SUNDAY/...
AS OF 230 PM THURSDAY...THE SHORT TERM LOOKS LIKE IT WILL BE MAINLY
A CONTINUATION OF THE RELATIVELY FLAT UPPER RIDGE OVER THE REGION
WITH THE MAIN WESTERLIES WELL TO OUR N. THERE IS A WEAKNESS IN THE
RIDGE OFF THE SOUTHEAST COAST BUT IT DOES NOT APPEAR TO AFFECT OUR
WEATHER. AT THE SURFACE...WE WILL REMAIN IN BETWEEN SEVERAL WEAK
CENTERS OF HIGH AND LOW PRESSURE THROUGH SATURDAY SO DIURNALLY
DRIVEN CONVECTION WILL BE THE RULE. TEMPS MAY BE A FEW DEGREES
COOLER THAN FRIDAY BECAUSE OF INCREASED CLOUD COVER. SUNDAY IS AN
INTERESTING DAY AS THE UPPER PATTERN STARTS TO CHANGE DURING THE
DAY. THE PROGRESSION OF AN UPPER LOW ACROSS THE GREAT LAKES AND
ONTARIO STARTS TO BUCKLE THE FLAT RIDGE OVER THE CAROLINAS. THE
MODELS SUGGEST THAT A COLD FRONT OVER THE OH VALLEY LATE SATURDAY
WILL PUSH INTO THE AREA ON SUNDAY. IF THE FRONT SLIPS TO THE SOUTH
EARLY SUNDAY MORNING...THEN THE DAY COULD BE RELATIVELY QUIET AS
SUGGESTED BY THE NAM. AM THINKING THAT THE BOUNDARY WOULD HANG UP
OVER THE MTNS ON SUNDAY...WHICH MEANS OUR POP WOULD BE MORE LIKE
WHAT IS IN THE GFS. HAVE THUS KEPT A DECENT CHANCE ACROSS MOST OF
THE REGION IN THE AFTERNOON. TEMPS WILL BE SIMILAR TO SATURDAY.

&&

.LONG TERM /SUNDAY NIGHT THROUGH THURSDAY/...
AS OF 245 PM EDT THURSDAY...IT LOOKS LIKE THE PATTERN SHIFT WILL
CONTINUE INTO THE EARLY PART OF THE MEDIUM RANGE. THE GUIDANCE IS
RELATIVELY CONSISTENT WITH TAKING THE CLOSED LOW INITIALLY OVER
ONTARIO AT 00Z MONDAY AND DIGGING AN UPPER TROF OFF THE EAST COAST.
AS THE UPSTREAM RIDGE AMPLIFIES...WE WILL END UP IN A NW FLOW FOR
MONDAY AND TUESDAY. AS THE PATTERN AMPLIFIES...IT WILL PUSH THE
FRONT TO OUR SOUTH BY MONDAY MORNING. AS A RESULT...EXPECT A LOW
CHANCE FOR CONVECTIVE PRECIP ON MONDAY AFTERNOON WITH HIGH PRESSURE
RIDGING DOWN FROM THE GT LAKES. AM TEMPTED TO REMOVE POP
ALTOGETHER...BUT IT SEEMS LIKE A FEW SHOWERS ALWAYS FORM OVER THE
HIGHER TERRAIN UNLESS THERE IS SOMETHING TO REALLY SUPPRESS THE
CONVECTION. THE PATTERN WILL SUPPORT MOVING THE HIGH CENTER PAST TO
OUR N THROUGH TUESDAY AND WEDNESDAY. THE LOWER HEIGHTS AND EASTERLY
FLOW WILL SPELL A RETURN TO COOLER TEMPS FOR THE FIRST HALF OF NEXT
WEEK. ALL THE GUIDANCE IS A CATEGORY OR SO COOLER FOR MON-WED.
EARLIER RUNS EVEN SUGGESTED THE POSSIBILITY OF LIGHT PRECIP AND SOME
COLD AIR DAMMING FOR TUESDAY AND/OR WEDNESDAY. THERE IS LESS SUPPORT
FROM THE NEW GUIDANCE FOR THIS TO HAPPEN...BUT HAVE STILL CUT A
CATEGORY OFF THE TEMPS. ON WEDNESDAY...THE SURFACE HIGH MOVES WELL
OFFSHORE SO EXPECT A RETURN TO WARMTH AND DIURNAL THUNDERSTORMS ON
THURSDAY WITH A BERMUDA HIGH.

&&

.AVIATION /21Z THURSDAY THROUGH TUESDAY/...
AT KCLT AND ELSEWHERE...DEEP CONVECTION WILL CONTINUE TO EXPAND
ACROSS THE MTNS AND ADJACENT FOOTHILLS THROUGH THE REST OF THE
AFTERNOON. KAVL AND KHKY WILL SEE THE GREATEST CHANCE FOR A TS.
OTHERWISE...CONVECTION IS EXPECTED EAST OF THE MTNS LATE THIS
AFTERNOON AND EARLY EVENING...ALL TAF SITES...EXCEPT KCLT...WILL
HAVE A CB IN THE TAF THIS AFTERNOON AND EARLY EVENING. KAVL HAS A
HIGH CHC FOR FOG LATE TONIGHT...I WILL INDICATE MVFR VIS AT THIS
TIME. FRIDAY...CONDITIONS LOOK VERY SIMILAR TO TODAY. I WILL
INDICATE LIGHT SSW WINDS AND SCT VFR LEVEL CU.

OUTLOOK...EXPECT DIURNAL CONVECTION EACH DAY WITH PATCHY EARLY MRNG
FOG...ESP MTN VALLEYS. IT STILL LOOKS LIKE A COLD FRONT WILL MOVE IN
FROM THE NW SUN...THEN HIGH PRES BUILD IN FROM THE N EARLY NEXT WEEK.
