NWS Greenville-Spartanburg, SC wrote its last area forecast discussion before the first event at Aug 14, 1:51 PM EST, 1 hour 51 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE GREENVILLE-SPARTANBURG SC 251 PM EDT TUE AUG 14 2012 .SYNOPSIS... A COLD FRONT WILL CROSS THE REGION OVERNIGHT REACHING THE COAST BY THURSDAY. HIGH PRESSURE WILL LINGER BRIEFLY BEFORE THE NEXT COLD FRONT MOVES TOWARD THE CAROLINAS LATE FRIDAY. && .NEAR TERM /THROUGH WEDNESDAY/... AS OF 145 PM...POPS HAD TO BE ADJUSTED AGAIN TO CHASE TRENDS. A HEALTHY CU FIELD CAN BE SEEN ON VISIBLE...BUT JUST DOESN/T SEEM TO BE ABLE TO BREAK THRU. THE 13Z HRRR IS THE CLOSEST TO REALITY...AND IT REALLY ONLY HAS A FEW CELLS DEVELOPING ACRS THE NC MTNS THRU THE AFTN HOURS. SO POPS WERE PUSHED BACK TO LATE AFTN/EVE...WHICH ARE PROBABLY STILL OVERDONE. TEMPS ARE STILL LAGGING. ONE THING TO NOTE IS THAT THE MODIFIED FFC SOUNDING THIS MORNING SHOWED THAT A FCST MAX TEMP OF 87-89 STILL RESULTED IN SOME CIN. STILL EXPECT A VORT MAX TO ENTER THE AREA LATER THIS AFTN...AND THAT MAY BE ENUF TO BREAK THE CAP. WE/LL SEE. LATER TONIGHT...AS WITH THE CONVECTION...FCST SNDGS AND MOISTURE PROGS ON THE NAM AND GFS ARE VAGUE ON HOW MUCH CLOUD COVER WILL LINGER OVERNIGHT. ANOTHER (STRONGER) VORT MAX...CURRENTLY OVER MO...WILL PROVIDE DECENT QG FORCING LATE TNGT INTO WED MORNING. THIS FEATURE WILL LIKELY KEEP SOME MID-HIGH CLOUDS AROUND. MEANWHILE...A COLD FRONT WILL PUSH INTO THE AREA TOWARD DAYBREAK...HELPING KEEP THINGS MIXED. SO TEMPS WILL BE NEAR NORMAL WITH PROBABLY NOT MUCH IN THE WAY OF FOG. I ALSO KEEP A LINGERING SLGT CHC TO LOW-END CHC POP DUE TO THE PASSAGE OF THE VORT MAX. WEDNESDAY...THE COLD FRONT SHUD BE ABLE TO PUSH THRU THE REST OF THE CWFA DURING THE DAY. GUIDANCE DOES TRY TO DEVELOP A LITTLE CONVECTION ACRS MAINLY THE SE ZONES WITH DAYTIME HEATING NEAR THE FRONT. OTHERWISE...SHUD BE A RELATIVELY DRY DAY WITH DECREASING CLOUDS AND HIGHS NEAR NORMAL. && .SHORT TERM /WEDNESDAY NIGHT THROUGH FRIDAY/... AS OF 245 PM TUESDAY...ZONAL FLOW DEVELOPS FOR THU AS SHORT WAVE MOVES EAST OF THE AREA. SFC HIGH PRESSURE BUILDS IN AS WELL. EXPECT DRYING LOW LEVELS AND WARMING MID LEVELS THU HELPING TO CAP THE ATMOS. SHUD BE A DRY FCST WITH LOWS A LITTLE BELOW NORMAL AND HIGHS NEAR NORMAL. HEIGHTS FALL FRI AS SHORT WAVES DIVE TOWARD THE AREA. THIS HELPS PUSH A COLD FRONT FROM THE OH VALLEY TO JUST WEST OF THE CWFA. LEE TROF DEVELOPS TO HELP PRODUCE LOW LEVEL CONVERGENCE. UPPER DIVERGENCE BEGINS TO INCREASE AS UPPER JET MOVES TOWARD THE AREA AS WELL. EXPECT INSTABILITY TO RETURN WITH MOISTENING LOW LEVELS AND COOLING MID LEVELS. BEST CHC FOR PRECIP WILL BE OVER THE MTNS WHERE MOISTURE AND FORCING ARE HIGHER...BUT SCT CONVECTION SHUD DEVELOP ALL AREAS BY LATE AFTERNOON. LOWS THU NITE RISE TO AROUND NORMAL WITH HIGHS FRIDAY NEAR TO SLIGHTLY ABOVE NORMAL. && .LONG TERM /FRIDAY NIGHT THROUGH TUESDAY/... AS OF 230 PM TUESDAY...MUCH BETTER AGREEMENT BETWEEN THE 12Z GFS AND THE 00Z ECMWF REGARDING THE DEVELOPING LONG WAVE TROF OVER THE ERN CONUS THAN BETWEEN THE 06Z GFS AND 00Z ECMWF. AS MENTIONED ABOVE... LONG WAVE TROF DEVELOPS OVER THE ERN CONUS AND REMAINS IN PLACE THRU THE PERIOD. A SERIES OF WEAK SHORT WAVES MOVE THRU THE FLOW WITH THE STRONGEST ON MONDAY. THE GFS THEN SHIFTS THE AXIS OF THE LONG WAVE EAST ON TUE WHILE THE ECMWF HOLDS IN IN PLACE. AT THE SFC..A COLD FRONT MOVES ACROSS THE AREA SAT...THEN STALLS TO OUR EAST AND SOUTH THRU THE PERIOD. THE WAVE ON MONDAY MAY HELP DRAG THE FRONT BACK TOWARD THE AREA BEFORE IT PUSHES SOUTH AND EAST OF US AGAIN FOR TUE. GOOD AGREEMENT ON AT LEAST SCT POP SAT WITH THE FRONT...THEN GUIDANCE DIFFERS FROM DAY TO DAY WITH PRECIP POTENTIAL DEPENDING ON WHERE ANY WAVES MOVE ALONG THE FRONT AND IF THEY CAN PULL MOISTURE BACK NORTH INTO THE CWFA. HAVE GONE WITH SCT POP SAT...SLIGHT CHC SUN/MON THEN DRY TUE. TEMPS REMAIN NEARLY STEADY NEAR TO SLIGHTLY BELOW NORMAL SAT THRU MON...THEN RISE BACK TO NEAR NORMAL FOR TUE. && .AVIATION /19Z TUESDAY THROUGH SUNDAY/... AT KCLT...A LOW CONFIDENCE FCST NEXT 24 HOURS...AS MODELS HAVING TOUGH TIME WITH CONVECTION AND CLOUD COVER OVERALL. BASED ON THE LATEST TRENDS...THINK CONVECTION WILL GET A LATE START IN THE NC MTNS...WITH ACTIVITY NOT REACHING THE VICINITY UNTIL CLOSER TO 00Z. SO I PUSHED THE TEMPO BACK TO 00Z. THEN AFTER 03Z...STILL A PROB30 FOR A COUPLE MORE HOURS. MEANWHILE...SW WINDS WILL BE AROUND 10 KNOTS OR SO WITH POSSIBLY A FEW GUSTS IN THE 15-18 KT RANGE. WIND DECREASE TO UNDER 5 KNOTS AFTER SUNSET. GUIDANCE A BIT VAGUE ON HOW MUCH MID AND HIGH CLOUDS LINGER OVERNIGHT. STILL EXPECT A FAIR AMT...SO BETWEEN WINDS AND CLOUD COVER...NO FOG IS EXPECTED EARLY WEDNESDAY. A WIND SHIFT TO NW WITH THE ARRIVAL OF A COLD FRONT IS EXPECTED AFTER DAYBREAK WEDNESDAY...BUT WINDS SHUD STAY FAIRLY LIGHT. ELSEWHERE...CONVECTION SLOW TO GET GOING...SO TEMPO GROUPS AND VCTS MENTIONS HAVE BEEN PUSHED BACK AT ALL SITES. CONFIDENCE ON TIMING AND COVERAGE IS STILL LOW. AS A COLD FRONT MOVES THROUGH EARLY WEDNESDAY MORNING...THE MODELS SHOW BREAKS IN LOW VFR CLOUD COVER. SW WINDS AROUND 10 KNOTS WITH OCCASIONAL LOW-END GUSTS TODAY (EXCEPT AT KAVL)...DECREASING TO 5 KNOTS TONIGHT. BETWEEN WINDS AND CLOUD COVER...FOG IS NOT EXPECTED EARLY WEDNESDAY...EVEN THO GUIDANCE DOES HAVE FOG IN THE MTN VALLEYS. A FRONTAL PASSAGE AND A WIND SHIFT ARE EXPECTED AFTER DAYBREAK WEDNESDAY...BUT WINDS SHUD REMAIN LIGHT. OUTLOOK...THE CENTER OF SURFACE HIGH PRESSURE WILL SETTLE OVER THE REGION ON WEDNESDAY AND REMAIN THROUGH THE WORK WEEK. A COLD FRONT WILL BRING SOME MOISTURE TO THE AREA LATE FRIDAY INTO SATURDAY.
