AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREENVILLE-SPARTANBURG SC
728 PM EDT FRI JUN 10 2011

.SYNOPSIS...
A WEAK RIDGE OF HIGH PRESSURE WILL PERSIST ACROSS THE AREA THROUGH
SATURDAY. A COLD FRONT WILL MOVE INTO THE REGION FROM THE NORTHWEST
ON SUNDAY...WITH HIGH PRESSURE AND SLIGHTLY COOLER TEMPERATURES
BUILDING SOUTHWARD INTO THE AREA BEHIND THE FRONT INTO NEXT WEEK.

&&

.NEAR TERM /THROUGH SATURDAY/...
2330 UTC UPDATE...POPS AND QPF HAVE BEEN INCREASED AROUND KGSP AND
DAVIE CO NC PER LATEST RADAR TRENDS.

AT 1745Z...VIS SATELLITE INDICATED ENHANCED CU OVER THE MTN RIDGES
WITH A SOLID CU FIELD OVER THE SOUTHERN CLT METRO AREA. LATEST SPC
MESOSCALE ANALYSIS INDICATES THAT LITTLE TO NO VALUES OF CIN. I
EXPECT TO SEE CU CONTINUE TO BUILD ACROSS THE RIDGES AND EAST OF
I-85 WITHIN A SFC TROF. DEEP CONVECTION SHOULD CONTINUE TO POPULATE
THESE TWO AREA THROUGH 0Z. SHRA/TSRA WILL REMAIN THROUGH MID
EVENING...THEN WILL ASHE OUT DURING THE LATE EVENING. CLEARING SKY
COVER AND LIGHT WINDS WILL REMAIN TONIGHT. AREAS WITHIN THE MTN
VALLEYS AND RECENT RAINFALL SHOULD DEVELOP LIGHT FOG AROUND DAWN.
LOWS TONIGHT ARE FORECAST TO RANGE FROM 60 WITHIN THE MTN VALLEYS TO
U60S EAST.

THE FZL THIS AFTERNOON WILL REMAIN BETWEEN 13.2 TO 13.5
KFT...PLACING THE 55 DBZ CORE HEIGHT AROUND 25 KFT. SHEAR WITHIN THE
LOW LEVELS IS NEARLY ZERO...SUPPORTING A PURE PULSE THUNDERSTORM
STORM MODE. IN ADDITION...DCAPE VALUES WILL LIKELY REMAIN LESS THAN
1000 J/KG. GIVEN THE LOW SHEAR AND DEEP MOISTURE IT APPEARS THAT A
COUPLE OF STORMS COULD PRODUCE EXCESSIVE RAINFALL. IN
ADDITION...MODERATE AFTERNOON AND EVENING INSTABILITY MAY SUPPORT A
FEW SVR TSRA. WE WILL CONTINUE TO MENTION BOTH THE SVR AND FLOODING
POTENTIAL IN THE HWO.

SATURDAY...ENVIRONMENT AGAIN APPEARS SUPPORTIVE OF EARLY AFTERNOON
SHRA/TSRA INITIATION ACROSS THE MTNS...SPREADING EAST ACROSS THE
FOOTHILLS AND PIEDMONT DURING THE LATE AFTERNOON AND EVENING.
CONSENSUS OF MOS GUIDANCE GENERALLY SUPPORTS A 1 TO 2 DEGREE
DECREASE IN DEWPOINTS SATURDAY AFTERNOON. THIS MAY RESULT IN GREATER
CIN ACROSS THE CWA...REMAINING INTO THE AFTERNOON HOURS. IN
ADDITION...CAPES MAY FAVOR THE 1000 TO 1500 J/KG RANGE. FORECAST
SOUNDINGS INDICATE VERY HIGH PWS...GREATER THAN 1.5 INCHES WITH
K-INDEX VALUES IN THE U30S. GIVEN SLOW STORM MOTIONS...IT APPEARS
THAT THE THREAT OF EXCESSIVE RAINFALL WILL INCREASE FROM TODAY. WE
WILL CONTINUE TO MENTION A FEW SEVERE STORMS AND EXCESSIVE RAINFALL
IN THE HWO FOR SATURDAY. HIGH TEMPERATURES ARE FORECAST TO RANGE
FROM THE U80S ACROSS THE MTNS TO L90S EAST.

&&

.SHORT TERM /SATURDAY NIGHT THROUGH MONDAY/...
AS OF 230 PM FRIDAY...AN AMPLIFICATION OF THE UPPER PATTERN IS STILL
EXPECTED THROUGH THE SHORT RANGE PART OF THE FCST...AS AN UPPER LOW
MIGRATES ACROSS EASTERN CANADA AND NEW ENGLAND. AS THE FLOW BUCKLES
AND AN UPPER TROF DIGS ALONG THE EAST COAST...A COLD FRONT INITIALLY
OVER THE OH VALLEY WILL BE DRIVEN SOUTHEAST ACROSS THE FORECAST
AREA...MOST LIKELY LATE SUNDAY. THERE IS A CHANCE THAT PRE-FRONTAL
CONVECTION COULD REACH THE MTNS BY SUNRISE SUNDAY SO THE POP STARTS
RAMPING UP FROM THE W SIDE OF THE MTNS VERY EARLY IN THE DAY. EXPECT
SUNDAY TO BE A CONVECTIVELY ACTIVE DAY AND THINK THE SREF HAS A GOOD
HANDLE ON THE EXPECTED PROGRESSION OF THE FRONTAL-ASSISTED
CONVECTION INTO SUNDAY EVENING. THE MODELS DRIVE THE FRONT SOUTH OF
THE REGION BY MONDAY MORNING...SO TEMPS SHOULD BE AT LEAST A
CATEGORY COOLER MONDAY. AT ISSUE IS THE MODELS HANDLING OF A WEAK
SHORT WAVE...PERHAPS CONVECTIVELY INDUCED...LATE IN THE DAY DROPPING
DOWN FROM THE NW THRU THE TN VALLEY. ALL THREE HAVE THIS
FEATURE...BUT THE GFS AND ECMWF DO NOT RESPOND. MEANWHILE...THE NAM
HAS A BIG MCS REACHING THE MTNS MONDAY AFTERNOON. FOR NOW...WILL
FOLLOW THE SREF WHICH HAS VERY LITTLE CHANCE OF ANY SIGNIFICANT
INSTABILITY...AND THUS NO PRECIP CHANCE.

&&

.LONG TERM /MONDAY NIGHT THROUGH FRIDAY/...
AS OF 230 PM FRIDAY...THE MEDIUM RANGE BEGINS MONDAY EVENING WITH
THE GENERAL IDEA THAT A SURFACE FRONT WILL BE WELL TO OUR SOUTH WITH
DRY HIGH PRESSURE RIDGING DOWN FROM THE GT LAKES. THIS SEEMS
REASONABLE WITH THE DEEP UPPER TROF EXPECTED OFF THE EAST COAST.
OBVIOUSLY...IF THE NAM IS CORRECT WITH SOME REMNANT MCS...WE WILL
HAVE TO REVISE THIS. THE OPERATIONAL GFS AND ECMWF KEEP THE WESTERN
CAROLINAS DRY THROUGH TUESDAY AND TUESDAY NIGHT AS THE CENTER OF THE
HIGH MOVES ACROSS THE MID ATLANTIC AND OFFSHORE. TEMPS SHOULD BE
CLOSE TO NORMAL IN THIS SCENARIO. THE PATTERN REMAINS SLOWLY
PROGRESSIVE AS THE UPPER TROF MIGRATES FURTHER OFFSHORE MIDWEEK.
WITH THE HIGH OFFSHORE WEDNESDAY...SOME MOISTURE WILL RETURN ON
WEDNESDAY WHICH WILL BRING A RETURN TO DIURNAL THUNDERSTORMS. THE
LATTER HALF OF THE WEEK LOOKS A LITTLE BUSIER. THE NEXT UPPER TROF
SHOULD MOVE OVER THE MIDWEST AND GT LAKES THURSDAY WHICH IS EXPECTED
TO PUSH A COLD FRONT DOWN ACROSS THE FCST AREA...THAT WILL LINGER
THROUGH FRIDAY. THE EXTRA FOCUS FOR CONVECTION AND BETTER MOISTURE
SHOULD BRING A BETTER CHANCE FOR SHOWERS AND STORMS THAT ARE NOT
NECESSARILY DIURNAL IN NATURE. TEMPS WILL CLIMB BACK ABOVE NORMAL.

&&

.AVIATION /00Z SATURDAY THROUGH WEDNESDAY/...
AT KCLT...CONVECTION TO THE NORTH OF THE FIELD WILL DIMINISH THIS
EVENING. WITH THE LOSS OF HEATING CLOUDS COVER SHOULD DECREASE.
LIGHT WINDS WILL BACK FROM SW TO SE OVERNIGHT. GUIDANCE DOES NOT
SUPPORT MORNING FOG RESTRICTIONS. LIGHT SOUTH WINDS CONTINUE
SATURDAY. ADDITIONAL CONVECTION ON SATURDAY WILL BE TOO SCATTERED TO
MENTION IN THE TAF.

ELSEWHERE...CONVECTION IN THE FOOTHILLS WILL GRADUALLY DIMINISH
THIS EVENING...AS WILL CLOUD COVER. LIGHT SOUTH WINDS WILL PERSIST
AT KGMU AND KGSP. WINDS ARE EXPECTED TO GO CALM AT KAVL...KHKY...AND
KAND...ALL OF WHICH REA EXPECTED TO SEE SOME DAYBREAK FOG. GUIDANCE
SUPPORTS MVFR VSBY AT KAVL...BUT ONLY LOW VFR AT KHKY AND KAND.
LIGHT SW WINDS ARE EXPECTED SATURDAY...WITH ADDITIONAL CONVECTION
TOO SCATTERED TO MENTION.

OUTLOOK...A COLD FRONT WILL MOVE IN FROM THE NORTHWEST SUNDAY...WITH
RESTRICTIONS ACCOMPANYING CONVECTION. HIGH PRESSURE WILL BUILD IN
FROM THE NORTH EARLY NEXT WEEK.
