NWS Greenville-Spartanburg, SC wrote its last area forecast discussion before the first event at Aug 17, 8:15 PM EST, 1 hour earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE GREENVILLE-SPARTANBURG SC 915 PM EDT FRI AUG 17 2007 .SYNOPSIS... A WEAK COLD FRONT WILL CONTINUE TO PUSH SOUTHEAST OF THE AREA TONIGHT AS HIGH PRESSURE BUILDS IN FROM THE GREAT LAKES. UPPER LEVEL RIDGING WILL BUILD OVER THE REGION THROUGH THE MIDDLE OF NEXT WEEK. && .NEAR TERM /THROUGH SATURDAY/... OUTSIDE OF ISOLD CONVECTION FAR S CWA SHORTLY AFTER 9 PM... SKIES ARE CLEARING ACROSS MOST OF AREA. WITH WEAK OUTFLOW BOUNDARIES OVER S CWA AND RESIDUAL MOISTURE...WILL KEEP A SMALL AREA OF SLIGHT CHC POP ALONG S FRINGE UNTIL MIDNIGHT. LOWS SHOULD BE A FEW DEGREES LOWER THAN THE PAST FEW NIGHTS BUT STILL ABOVE AVG. DRY FORECAST SATURDAY AS DRIER AIR MOVES INTO THE AREA. HI TEMPS WILL BE COOLER THAN THE PAST FEW DAYS...BUT STILL ABOVE AVG. UPPER RIDGING BUILDS BACK INTO THE AREA WITH THICKNESSES AND H85 TEMPS REMAINING ABOVE NORMAL. LOOK FOR HIGHS RANGING FROM THE UPPER 90S DOWN NEAR GREENWOOD AND ABBEVILLE...TO LOW 90S UP AROUND HICKORY AND STATESVILLE. TEMPS IN THE MTNS WILL BE MOSTLY IN THE UPPER 70S AND 80S...BUT AROUND 90 IN LOWER MTN VALLEYS. && .SHORT TERM /SATURDAY NIGHT THROUGH MONDAY/... BOTH THE GFS AND THE NAM DEPICT SOME UPGLIDE MOISTURE DEVELOPING NORTH OF WEAK FRONTAL BOUNDARY BY SUNDAY MORNING. IN FACT...THE NAM INDICATES A COLD AIR DAMMING-TYPE SETUP DURING THE DAY SUNDAY...AND MET GUIDANCE IS ABOUT 10 DEGREES COOLER THAN THE MAV. IT SEEMS UNLIKELY THAT WIDESPREAD...PERSISTENT LOW CLOUDS WILL AFFECT THE AREA THROUGH THE DAY SUNDAY...AS THE MODELS DEPICT THIS AREA OF MOISTURE AS BEING TRANSIENT...AS OPPOSED TO LOCKING IT IN OVER THE AREA. (NOT TO MENTION UPGLIDE WILL BE WEAK AND THE AIRMASS WON/T BE ALL THAT STABLE.) THEREFORE...WE WILL NUDGE MAX TEMPS TOWARD THE WARMER MAV NUMBERS...BUT UNDERCUT THESE BY A COUPLE OF DEGREES...AS IT SEEMS LIKE THERE SHOULD BE AT LEAST A BRIEF PERIOD OF LOW STRATUS...ESP ACROSS THE EASTERN ZONES. WITH WEAK BOUNDARY STILL IN THE AREA AND SOME MOISTURE AROUND...WE WILL CONTINUE TO CARRY SLIGHT CHANCE POPS ACROSS THE REGION SUN AFTERNOON...ALTHOUGH MODEL INSTABILITY IS NOT ALL THAT IMPRESSIVE. FOR SUNDAY NIGHT...THE NAM AND THE GFS ARE AT ODDS WITH HOW FAR SOUTH FRONTAL BOUNDARY ASSOCIATED WITH DEEPENING EASTERN TROUGH WILL PENETRATE BEFORE STALLING OUT. THE GFS BRINGS MOISTURE ASSOCIATED WITH THIS FEATURE TO THE NC/VA BORDER. MEANWHILE...THE NAM HOLDS THE BETTER MOISTURE ACROSS SOUTHERN NEW ENGLAND INTO THE GREAT LAKES. QUITE A DISCREPANCY. REGARDLESS OF WHICH SOLUTION VERIFIES CLOSER TO REALITY...IT REALLY DOESN/T MATTER AS FAR AS OUR CWFA IS CONCERNED. THE GFS SOLUTION SUGGESTS THAT MCS ACTIVITY COULD BRUSH THE FAR NORTHERN ZONES...BUT THIS ONLY WARRANTS A SLIGHT CHANCE ATTM. UPPER HIGH CENTERED OFF THE GA COAST WILL KEEP THE BETTER FORCING AND MOISTURE NORTH OF THE REGION FOR MONDAY...SO THE POP WILL BE SLIGHT CHANCE AT BEST FOR DIURNAL CONVECTION. && .LONG TERM /MONDAY NIGHT THROUGH FRIDAY/... THE EXTENDED PERIOD BEGINS WITH AN UPPER HIGH CENTERED OVER THE SOUTHEAST...WITH A RIDGE AXIS EXTENDING NORTHWARD INTO CENTRAL CANADA. THIS UPPER HIGH WILL RETROGRADE SLIGHTLY WESTWARD AND REMAIN THE DOMINANT FEATURE THROUGH THURS MORNING. BY FRI...A DEVELOPING LOW AMPLITUDE TROF OVER THE CENTRAL CONUS WILL BEGIN TO ERODE THE WESTERN PERIPHERY OF THE RIDGE FOR THE WEEKEND. BEST DEEP LAYER MOISTURE LOOKS TO REMAIN NORTH OF THE FA UNTIL LATE IN THE PERIOD. ACCORDINGLY...POPS ARE QUITE LOW WITH RIDGE IN CONTROL...LACK OF DEEP LAYER MOISTURE AND INSTABILITY. SLGHT CHC POPS ARE ADVERTISED EVERYWHERE BY LATE IN THE EXTENDED AS THE RIDGE BREAKS DOWN. TEMPS THROUGHOUT THE PERIOD CONTINUE WARM...RUNNING 4-5 DEGREES ABOVE CLIMO NORMALS. && .AVIATION /01Z SATURDAY THROUGH WEDNESDAY/... FRONT AND ASSOC CONVECTION HAVE MOVED WELL S OF TAF SITES WITH SKIES CLEARING OVER TERMINAL AREAS. EXPECT LIGHT N TO NE WINDS OVERNIGHT. HAZE MAY STILL GO MVFR VCNTY KCLT BRIEFLY THIS EVE BUT SHOULD INPROVE IN LIGHT NE FLOW OVERNIGHT. KAVL WILL COME WITHIN A FEW DEGREES OF CROSSOVER TEMP TONIGHT SO HAVE MVFR FOG/HAZE THERE LATE TONIGHT THRU EARLY MORNING HOURS...WITH BRIEF TEMPO IFR AROUND DAYBREAK. AVIATION OUTLOOK...LOOK FOR GENERALLY DRY CONDITIONS WITH JUST A SLIGHT CHANCE OF SHWRS/TSTMS SUN THRU WED. EARLY MORNING MVFR FOG AND HAZE ARE POSSIBLE EACH DAY...MAINLY AT KAVL. && .GSP WATCHES/WARNINGS/ADVISORIES... GA...NONE. NC...NONE.
