NWS Greenville-Spartanburg, SC wrote its last area forecast discussion before the first event at Jul 23, 12:47 PM EST, 45 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE GREENVILLE-SPARTANBURG SC 147 PM EDT MON JUL 23 2012 .SYNOPSIS... A WEAK UPPER LEVEL RIDGE WILL BUILD ACROSS THE REGION AND PERSIST THROUGH THE END OPF THE WORK WEEK. A COLD FRONT IS THEN EXPECTED TO PUSH INTO THE CAROLINAS AND NORTHEAST GEORGIA LATE FRIDAY AND BECOME STATIONARY OVER THE WEEKEND. && .NEAR TERM /THROUGH TONIGHT/... AS OF 145 PM...SHRA/TSTMS ARE DEVELOPING ALONG THE BLUE RIDGE AS EXPECTED THIS AFTN...AND THE IMMEDIATE NEAR TERM PART OF THE FORECAST IS IN GOOD SHAPE. PREVIOUS DISCUSSION... SATELLITE IMAGERY THIS MORNING REVEALS MOSTLY CLEAR SKIES ACROSS THE FORECAST AREA WITH THE EXCEPTION OF SOME MID LEVEL CLOUDS OVER THE HIGHER TERRAIN. MORNING FOG HAS DISSIPATED WITH SURFACE HEATING AND WILL SOON BE REPLACED WITH CUMULUS DEVELOPMENT. WATER VAPOR IMAGERY INDICATES A SHORTWAVE MOVING ACROSS EASTERN KENTUCKY AND SOUTHERN WEST VIRGINIA...WHICH BY THIS AFTERNOON WILL BE MOVING INTO NORTH CAROLINA AND PROVIDE ADDITIONAL LARGE SCALE LIFT TO AID CONVECTION. 12Z GSO SOUNDING SHOWED THE ENTIRE ATMOSPHERE FROM 600 MB TO THE SURFACE HAD WARMED WITH A 700MB TEMPERATURE CLOSE TO +10C AND THIS SHOULD PROVIDE A STRONGER CAP THAN YESTERDAY. HOWEVER...WITH THE UPPER SUPPORT ARRIVING DURING PEAK HEATING ALL MODELS ARE INDICATING SOME CONVECTION DEVELOPING MID AFTERNOON ACROSS THE EASTERN PART OF THE FORECAST AREA. CURRENT POP CONFIGURATION OF HIGHER CHANCE TO THE NORTH AND EAST WITH LOWER CHANCE POPS SOUTHWEST CLOSER TO THE INFLUENCE OF THE UPPER RIDGE SEEMS REASONABLE. TEMPERATURES THIS AFTERNOON SHOULD BE WARMER THAN ON SUNDAY. && .SHORT TERM /TUESDAY THROUGH WEDNESDAY/... AS OF 130 AM EDT MONDAY...THE SHORT TERM FCST PICKS UP AT 12Z ON TUESDAY WITH THE UPPER RIDGE SLOWLY FLATTENING AND A BROAD UPPER TROF MOVING OVER SE CANADA. H5 SHORTWAVE ENERGY WILL PASS TO THE NORTH TUES AFTERNOON AND THEN DISSIPATE OFFSHORE. FOR THE REMAINDER OF THE PERIOD...THE UPPER LVL PATTERN WILL FLATTEN WITH WEAKER FLOW ALOFT. ON TUESDAY...A COLD FRONT ASSOCIATED WITH A LARGE CANADIAN SFC LOW WILL MOVE OVER THE REGION AND SHIFT LOW LVL WINDS TO MORE OF A NWLY TO WLY PREVAILING DIRECTION. THE APPROACH OF THE FRONT WILL INCREASE THE POTENTIAL FOR MORE WIDESPREAD CONVECTION DURING THE AFTERNOON/EVENING WITH THE BEST CHANCES OVER THE HIGHER TERRAIN ALONG AND NORTH OF I-40. THE OVERALL PATTERN CHANGES LITTLE THROUGH WEDNESDAY AS UPPER HEIGHTS CONTINUE TO FALL A BIT. CONDITIONS SHOULD REMAIN CONDUCIVE FOR ADDITIONAL DIURNALLY ENHANCED TSRA WITH ADDITIONAL CLOUDS AND DEEP CONVECTION. AN INFLUX OF MARGINALLY COOLER AIR WILL MAKE INROADS INTO NORTH CAROLINA LATER IN THE DAY...ALTHOUGH HIGHS BOTH DAYS SHOULD REACH THE MID 90S OVER THE LOWER TERRAIN AND MID TO UPPER 80S OVER THE HIGHER TERRAIN. && .LONG TERM /WEDNESDAY NIGHT THROUGH MONDAY/... AS OF 100 PM EDT MONDAY...THE LATEST OP MODELS AND GFS ENSEMBLE MEMBERS ARE IN GOOD AGREEMENT FRI THROUGH THE WEEKEND WITH A OMEGA BLOCK SETTING UP ACROSS THE NRN ATL OCEAN. THIS WILL INDUCE AND DEEPEN ANOTHER EAST COAST TROF AND ALLOW A COLD FRONT INTO THE AREA BY SAT. THE FRONT IS EXPECTED TO STALL ACROSS THE CWFA SAT THROUGH SUN AND PERHAPS LIFT A LITTLE NORTH ON MON. THE STRONGEST UPPER FORCING WILL REMAIN NORTH OF THE AREA...HOWEVER GOOD OVERALL DYNAMICAL LIFT AND H3 DIV ALONG WITH PLENTY OF LLVL INSTABILITY WILL BE AVAILABLE FOR STRONG TO SEVERE DIURNAL TSTMS EACH DAY EXPECT PERHAPS SUN. NOCTURNAL ACTIVITY IS ALSO PROBABLE FRI/SAT NIGHT WITH THE FROPA LATE FRI AND A REINFORCING S/W PUSHING IN LATE SAT. POPS WERE MAINTAINED AT NEAR CLIMO...HOWEVER IF THIS PATTERN AND S/W TIMING PERSISTS OVER THE NEXT COUPLE MODEL RUNS...AN INCREASE IN POPS WILL BE WARRANTED FOR FRI/SAT. SUN LOOKS TO BE THE DRIEST DAY WITH FAIRLY STRONG HIPRES BUILDING IN...YET THE FRONT WILL BE SHUNTED JUST TO THE SOUTH...SO SLIGHT CHANCE POPS WERE CARRIED THROUGH THE DAY. MON WILL BE ACTIVE AGAIN AS ANOTHER SHOT OF UPPER ENERGY ROUNDS THE WRN RIDGE AND TRAVERSES THE REGION. MAX AND MIN TEMPS WILL BE RIGHT AROUND OR PERHAPS A COUPLE DEGREES ABOVE NORMAL FRI/SAT. WITH NW/LY FLOW SETTING UP SUN...EXPECT A COUPLE DEGREES COOLER IN THE MTNS SUN AND PERHAPS EVEN MON. YET...A GOOD DOWNSLOPE WARMING COMPONENT WILL ENABLE MAXES RIGHT AROUND NORMAL OVER THE NON/MTNS BOTH SUN AND MON. && .AVIATION /18Z MONDAY THROUGH SATURDAY/... AT KCLT...SCT TSTMS ARE BEGINNING TO DEVELOP OVER THE NC FOOTHILLS. USING THE DISTANCE TIME OF ARRIVAL TOOL IN AWIPS...THE CELL IN EASTERN MCDOWELL COUNTY WOULD AFFECT THE AIRFIELD AROUND 2015 UTC. WHILE THAT INDIVIDUAL CELL WILL PROBABLY DIE...MORE STORMS ARE LIKELY ALONG THE OUTFLOW BNDRY AND A TEMPO GROUP FOR THUNDER HAS BEEN ADDED FROM 20-22 UTC. WINDS WILL BE VARIABLE WITH THE LEE TROUGH OVER THE AIRFIELD THIS AFTERNOON. HOWEVER...MOST SURROUNDING SITES ARE OUT OF THE WSW AND THAT/S WHAT I/LL CARRY AT KCLT. NO CIG OR VISBY PROBLEMS ARE EXPECTED OVERNIGHT AND CONVECTION SHOULD DIMINISH AFTER SUNSET. AND ELSEWHERE...SCT TSTMS ARE DEVELOPING ALONG THE BLUE RIDGE AS WELL AS BACK INTO ERN TN. WILL CARRY VCTS AT ALL AIRFIELDS...STARTING EARLIEST AT KAVL AND KHKY...AND A LITTLE LATER OVER THE UPSTATE AS IT WILL TAKE A COUPLE HOURS FOR OUTFLOW BNDRYS TO MAKE IT TOWARD THE I-85 CORRIDOR. WINDS WILL GENERALLY BE OUT OF THE W TO WSW THIS AFTN...WITH KAVL OUT OF THE NW. THE WINDS WILL BE VARIABLE AT TIMES OVER THE UPSTATE AS A WEAK LEE TROUGH IS OVER THAT AREA. SOME MVFR FOG IS POSSIBLE AT KAVL...BUT NOT LOOKING FOR ANY SIGNIFICANT CIG OR VSBY RESTRICTIONS OVERNIGHT...UNLESS AN AIRFIELD HAPPENS TO GET A HEAVY SHRA. OUTLOOK...SHOWER AND TSTM ACTIVITY WILL INCREASE A LITTLE OVER THE REGION TUE AND WED AS A WEAK FRONT DROPS INTO THE REGION. NOT LOOKING FOR MUCH IN THE WAY OF OVERNIGHT RESTRICTIONS OUTSIDE OF AREAS THAT SEE LOCALLY HEAVY RAIN. ANOTHER FRONT MAY BRING MORE WIDESPREAD CONVECTION AGAIN ON FRIDAY.
