Area forecast discussion, Jul 5, 7:51 PM EDT, 37 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREENVILLE-SPARTANBURG SC
751 PM EDT THU JUL 5 2012

.SYNOPSIS...
A WEAK LOW PRESSURE TROUGH WILL GIVE WAY TO UPPER LEVEL RIDGING THIS
WEEKEND MAINTAINING THE HOT TEMPERATURES. AN UPPER LEVEL TROUGH OF
LOW PRESSURE ALONG WITH AN ENCROACHING FRONT WILL DEVELOP ACROSS THE
REGION NEXT WEEK RESULTING IN DAILY THUNDERSTORM CHANCES AND STEADILY
LESS HOT CONDITIONS.

&&

.NEAR TERM /THROUGH FRIDAY NIGHT/...
AS OF 745 PM...BAND OF SEVERE THUNDERSTORMS HAVE TRACKED WEST OF THE
I-26 CORRIDOR. CONVECTION SHOULD CONTINUE TO DEVELOP ALONG AND
FOLLOWING THE LEADING EDGE OF WELL DEFINED GUST FRONT BOUNDARIES
ACROSS THE WESTERN UPSTATE AND NE GA THIS EVENING. I WILL CANCEL
COUNTIES ACROSS THE NRN NC MTNS...FOOTHILLS...AND PIEDMONT. COUNTIES
SOUTH WILL REMAIN UNTIL 9 PM. I WILL UPDATE FORECAST TO ADJUST POP
TREND AND CHANGES TO WATCH COUNTIES.

AS OF 215 PM...CONVECTION HAS BEEN FIRING UP OVER THE PAST COUPLE OF
HOURS AND WE ARE NOW UNDER A SVR THUNDERSTORM WATCH FOR OUR ENTIRE
CWFA. DISCRETE CELLS HAVE BEEN FORMING MOSTLY OVER THE UPSTATE AND
THE NC FOOTHILLS THUS FAR. STILL EXPECTING MORE TO DEVELOP OVER THE
MTS AS THE AFTERNOON WEARS ON BUT AS OF 215PM...IT HAS BEEN QUITE
OVER THE HIGHER TERRAIN. CURRENT LAPSE SOUNDINGS MAINTAIN
CONSIDERABLE INSTABILITY AND DCAPE OVER THE CWFA WITH VERY MINIMAL
SHEAR. SO...I DONT EXPECT MUCH SUBSTANTIAL ORGANIZATION FROM ANY
CELLS THAT DEVELOP...HOWEVER A LINE OF TS COULD MAINTAIN ITSELF IS
TRIGGERED BY STRONG OUTFLOW BOUNDARIES. FREEZING LVLS ARE AROUND
15KFT MSL SO IT WILL TAKE SOME TALL CORES TO PRODUCE LARGE HAIL AT
THE SFC...BUT WITH THE RELATIVELY DRY AIR IN THE LOWER LVLS...THE
POTENTIAL FOR STRONG DOWNBURSTS IS GOOD. STILL EXPECT HIGH TEMPS
NEAR 100 OVER THE LOWER ELEVATIONS AND MID TO UPPER 80S FOR THE MTS.
EXPECT THINGS TO QUITE DOWN LATER TONIGHT AND INTO THE EARLY MORNING
HOURS AS WE COOL. PATCHY TO AREAS OF FOG ARE POSSIBLE IN THE MT
VALLEYS FOR A FEW HOURS TOMORROW MORNING IF DEWPTS STAY UP.

TOMORROW...SHOULD BE SIMILAR TO TODAY WITH THE UPPER RIDGE DRIFTING
FARTHER EAST OVER THE OHIO RIVER VALLEY AND ANOTHER HOT SUMMERTIME
DAY ON TAP. EXPECTING LESS UPPER SHORTWAVE ENERGY OVERALL...SO I
BROUGHT POPS DOWN TO JUST SOLID CHANCE OVER THE HIGHER TERRAIN.

&&

.SHORT TERM /SATURDAY THROUGH SUNDAY/...
AS OF 240 PM THURSDAY...H5 HEIGHTS RISE ACROSS THE REGION SAT AS A
RIDGE AXIS BUILDS IN FROM THE W...WITH WEAK SHORTWAVES PUSHING DOWN
OVER THE AREA FROM THE N. WITH DEW POINTS AND PW STAYING RELATIVELY
HIGH EXPECT A CONTINUATION OF SCT DIURNAL CONVECTION...MAINLY OVER
THE MTNS WHERE LOW LEVEL CONVERGENCE WILL BE BEST. HIGHS REMAIN
ABOVE AVG AND HEAT INDEX VALUES OF 102-104 WILL BE LIKELY IN THE
AFTN AND A HEAT ADVSRY MAY BE NEEDED IF AREA WARMS A DEG OR SO
HIGHER. MODELS ARE IN DECENT AGREEMENT SHOWING THE RIDGE WEAKENING
SUN AS A TROF MOVES ACROSS THE NE US. SINCE BEST LOW LEVEL
CONVERGENCE REMAINS OVER THE W CWA WE KEPT SCT CONVECTION ACROSS THE
MTNS AND ADJACENT FOOTHILLS...MAINLY NORTH OF I-85...WITH ISOLATED
ELSEWHERE. HIGHS REMAIN ABOVE AVG SO EXPECT HEAT INDEX VALUES ABOVE
100 DEG E OF THE MTNS.

&&

.LONG TERM /SUNDAY NIGHT THROUGH THURSDAY/...
AS OF 100 PM THURSDAY...MEDIUM RANGE MODELS ARE STILL ADVERTISING
THE ONSET OF EASTERN CONUS L/WV TROUGH AND THE ENCROACHMENT OF
ELONGATED FRONTAL BOUNDARY FOR THE START OF THE PERIOD. WITH
COMMENCEMENT OF PATTERN CHANGE...WILL NUDGE DIURNALLY ENHANCED TSTM
CHANCES UPWARD AND MAX TEMPS DOWNWARD FOR MONDAY. WITH BNDRY PROGGED
TO LINGER IN THE VICINITY THRU TUESDAY...ROBUST...SOLID TSTM CHANCES
WILL CONTINUE AND THE TREND FOR LESS WARM TEMPERATURES WILL CONTINUE
AS WELL WITH MAX TEMPS PROGGED AROUND IF NOT A TAD BELOW CLIMO. BY
THE END OF PERIOD...MEAN L/WV TROFINESS FILLS JUST NOMINALLY...
AND WAVY LLVL BNDRY IS PROGGED TO LINGER SOMEWHERE ACRS THE SE
CONUS. BASED ON THIS SETUP...WOULD EXPECT DAILY TSTM CHANCES TO
REMAIN ABOVE CLIMO WHILE MAX TEMPS SHOULD AVERAGE A LITTLE BELOW
AVERAGE.

&&

.AVIATION /00Z FRIDAY THROUGH TUESDAY/...
AT KCLT AND ELSEWHERE...KAVL...HKY...KCLT WILL REMAIN FREE OF TSRA
OVERNIGHT. KGSP...KGMU...KAND...WILL SEE TSRA EARLY IN THIS TAF
PACKAGE AS COOL POOLS TRACK NE TO SW. MTN VALLEYS MAY SEE LIGHT FOG
DEVELOP AROUND SUNRISE...ALL OTHER SITES VFR OUTSIDE EVENING TSRA.
TSRA MAY DEVELOP DURING THE LATE AFTERNOON AND EVENING ON FRIDAY.
BASED ON THE EXPECTED CONVECTION...I WILL INCLUDE A PROB30 FOR ALL
TAF SITES. WINDS SHOULD FAVOR A NORTH DIRECTION WITH SPEEDS LESS
THAN 10 KTS.

OUTLOOK...ISOLATED TO SCATTERED AFTN/EVE SHRA/TSRA EXPECTED EACH DAY
THROUGH THE WEEKEND...WITH AREAS OF MORNING FOG/STRATUS
POSSIBLE...ESP IN THE MTN VALLEYS.
