AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREENVILLE-SPARTANBURG SC
321 PM EDT SAT JUL 24 2010
.SYNOPSIS...
HIGH PRESSURE OFF THE EAST COAST WILL CONTINUE TO KEEP THE HOT AND
HUMID CONDITIONS OVER THE REGION THROUGH THE WEEKEND. A WEAK COLD
FRONT WILL APPROACH FROM THE NORTH ON MONDAY AND AFFECT THE AREA
INTO MID WEEK.
&&
.NEAR TERM /THROUGH SUNDAY/...
AT 18Z...TEMPS AT KCLT AND KGSP REMAIN WITHIN A FEW DEGREE OF RECORD
HIGHS...SEE CLIMATE SECTION BELOW. BASED ON THE LATEST OBS...I
EXPANDED THE HEAT ADVISORY ACROSS THE UPSTATE AND INTO NE GA.
LATEST WATER VAPOR IMAGES INDICATES A WEAK DISTURBANCE OVER THE
UPSTATE OF SC...DRIFTING NORTHWEST. A BROKEN LINE OF DEEP CONVECTION
MAY CONTINUE TO FILL IN ALONG THE SC/NC STATE LINE THROUGH THE LATE
AFTERNOON. MTN RIDGES WILL LIKELY SEE AN INCREASE IN COVERAGE
THROUGH THE EARLY EVENING. I WILL INCREASE COVERAGE TO CHC ALONG THE
FAVORED AREAS. THE 12Z FREEZING LEVEL AT KGSO WAS OVER 17 KFT WITH
KFFC AT 17 KFT. DCAPE VALUES SHOULD RANGE FROM 1100-1400 J/KG ACROSS
THE FOOTHILLS AND PIEDMONT AND 500 J/KG ACROSS THE MTNS. IT APPEARS
THAT A FEW TSRA MAY PRODUCE STRONG GUSTY WINDS...LARGE HAIL LOOKS
VERY UNLIKELY.
TONIGHT...CONVECTION WILL ASHE OUT WITH LOSS OF DAYTIME
HEATING...LEAVING JUST SOME THIN DEBRIS CLOUDINESS OVERNIGHT.
ANOTHER MUGGY NGT EXPECTED WITH LOWS MAINLY IN THE 60S MTNS AND
UPPER 70S PIEDMONT.
SUNDAY...BASED ON A BLEND OF MOS AND PERSISTENCE...HIGH TEMPS SHOULD
PEAK IN NEAR 100 EAST OF THE MTNS AND L90S WITHIN THE MTN VALLEYS.
DEWPOINTS WILL LINGER IN THE U60S...PRODUCING ANOTHER AFTERNOON WITH
HEAT ADVISORY CRITERIA ALONG AND EAST OF I-85. APPROACHING COLD
FRONT AND DIURNAL INSTABILITY WILL SUPPORT SCT COVERAGE OF TSRA
ACROSS THE MTNS AND ADJACENT FOOTHILLS...SCHC EAST.
&&
.SHORT TERM /SUNDAY NIGHT THROUGH TUESDAY/...
AS OF 230 PM SATURDAY...UPPER RIDGE STILL EXPECTED TO WEAKEN EVER SO
SLIGHTLY ON MONDAY AND BEGIN S SLOW SOUTHWARD AND WESTWARD DRIFT
TUE. AT THE SFC...A COLD FRONT SLOWLY BACKDOORS ITS WAY INTO THE
AREA SUNDAY NIGHT...THEN STALLS OVER THE AREA MONDAY. THE FRONT
BEGINS TO SLOWLY LIFT BACK NORTH ON TUE...AS IT WEAKENS. WITH
COPIOUS MOISTURE OVER THE AREA AND INCREASED LOW LEVEL FORCING FROM
THE FRONT AND INCREASED UPPER SUPPORT FROM THE WEAK SHORT WAVES AND
UPPER DIVERGENCE...EXPECT AT LEAST SCT CONVECTION TO DEVELOP EACH
DAY. ALTHOUGH NOT CURRENTLY FCST...WOULD NOT BE SURPRISED IF
NUMEROUS COVERAGE DEVELOPS...ESPECIALLY ACROSS THE MTNS. LOWS REMAIN
WELL ABOVE NORMAL EACH NITE...WITH HIGHS FINALLY COOL FROM THE VERY
HIGH WEEKEND VALUES...BUT STILL REMAIN ABOVE NORMAL.
&&
.LONG TERM /TUESDAY NIGHT THROUGH SATURDAY/...
AS OF 220 PM SATURDAY...MODELS CONSISTENT RETROGRADING THE CENTER OF
THE UPPER RIDGE TO THE CENTRAL US BY NEXT WEEKEND. A SERIES OF WEAK
SHORT WAVES WILL MOVE ACROSS THE AREA IN THE NW FLOW BETWEEN THE
DEPARTING RIDGE AND DEVELOPING TROF OFF THE EAST COAST. AT THE
SFC...COPIOUS MOISTURE WILL REMAIN OVER THE AREA ALONG WITH A WEAK
BAROCLINIC BOUNDARY LEFT OVER FROM THE DISSIPATING FRONT FROM
EARLIER IN THE WEEK. ANOTHER COLD FRONT BACKDOORS ITS WAY INTO THE
AREA BY NEXT WEEKEND...KEEPING THE LOW LEVEL FORCING OVER THE AREA.
ALL THIS SHUD LEAD TO SCT DIURNAL CONVECTION EACH DAY. THICKNESSES
AND H85 TEMPS CHANGE VERY LITTLE EACH DAY WITH THE RELATIVELY
STAGNANT PATTERN. TEMPS WILL REMAIN ABOVE NORMAL THRU THE
PERIOD...BUT NOT QUITE AS WARM AS RECENT VALUES.
&&
.AVIATION /20Z SATURDAY THROUGH THURSDAY/...
AT KCLT AND ELSEWHERE...VFR CONDITIONS EXPECTED NEXT 24 HRS AT ALL
SITES. A WEAK PASSING VORT MAX MAY SUPPORT THE DEVELOPMENT OF SCT TO
ISO SHRA/TSRA ACROSS THE MTNS AND OVER THE FOOTHILLS.
CURRENTLY...THE CU FIELD HIGHLIGHTS THE NC FOOTHILLS AND MTNS FOR
INITIAL SHRA/TSRA. FUTURE OUTFLOWS WILL DETERMINE THE PLACEMENT OF
ADDITIONAL STORMS. AT THIS TIME I WILL INCLUDE A MENTION OF CB AT
KHKY. CROSSOVER TEMPERATURES AT KAVL ARE ALREADY TOO LOW TO SUPPORT
A MENTION FOG AT KAVL TONIGHT...IF THE TERMINAL REMAINS RAIN FREE.
WINDS WILL REMAIN LIGHT FROM THE SW THROUGH THE TAF PERIOD.
OUTLOOK...MAINLY JUST ISOLD AFTERNOON AND EVENING THUNDERSTORMS
SUNDAY...THEN INCREASED COVERAGE MON AND TUE AFTNS. MORNING FOG
POTENTIAL AT KAVL INCREASES MON AND TUE AS WELL.
&&
.CLIMATE...
MAXIMUM TEMPERATURES WILL APPROACH RECORD HIGHS IN A FEW LOCATIONS
ON SUNDAY.
