NWS Greenville-Spartanburg, SC wrote its last area forecast discussion before the first event at Jul 9, 1:28 PM EST, 17 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE GREENVILLE-SPARTANBURG SC 228 PM EDT MON JUL 9 2012 .SYNOPSIS... A COLD FRONT WILL SLOWLY DRIFT SOUTH INTO OUR AREA TODAY. THIS FRONT IS WILL BECOME STATIONARY ACROSS THE CAROLINAS AND GEORGIA...AND WILL REMAIN IN THE AREA THROUGH FRIDAY. && .NEAR TERM /THROUGH TUESDAY/... CONVECTION GETTING AN EARLY START AS EXPECTED WHICH WAS SLIGHTLY SLOWER THAN THE MESOSCALE MDLS SUGGESTED. GREATEST COVERAGE STILL EXPECTED OVER THE MTNS AND ALONG THE CONVERGENCE BOUNDARY ACROSS NE GA...INTO THE UPSTATE AND THE SRN FOOTHILLS AND PIEDMONT OF NC. ONLY SLIGHTLY LESS COVERAGE...STILL NUMEROUS...IS EXPECTED OVER THE SRN PORTIONS OF NE GA...THE UPSTATE AND THE NRN MTNS AND I-40 CORRIDOR OF NC. ANY OF THE STORMS COULD BECOME SEVERE WITH DAMAGING WINDS AND POSSIBLY LARGE HAIL GIVEN THE AT LEAST MODERATE INSTABILITY AND DCAPE VALUES FROM 800 J/KG NORTH TO 1500 J/KG SOUTH. EFFECTIVE BULK SHEAR STILL FCST TO INCREASE TO AS MUCH AS 25 KTS ACROSS THE I-40 CORRIDOR...SO THAT AREA HAS THE GREATEST POTENTIAL FOR ORGANIZATION. STILL...ORGANIZED STORMS COULD DEVELOP SOUTH OF THERE GIVEN THE LOW LEVEL CONVERGENCE BOUNDARY IN PLACE. ALSO...COLD POOL AND OUTFLOW BOUNDARY INTERACTIONS WILL LIKELY BE STRONGER ACROSS THE SOUTH WITH THE HIGHER DCAPE. HAVE ALREADY INCLUDED SVR TSRA WORDING IN THE FCST THRU 00Z TO COVER THE POTENTIAL. STORMS WILL LINGER INTO THE EVENING THEN TAPER OFF FROM SW TO NE AS INSTABILITY WANES. SH/TSRA COULD LINGER OVERNIGHT GIVEN THE UNSTABLE AIRMASS AND BOUNDARY. HOWEVER...THE COVERAGE WOULD BE SCT AT BEST. PATCHY FOG POSSIBLE AGAIN...ESP MTN VALLEYS AND FOOTHILLS. LOWS AS MUCH AS 5 DEGREES ABOVE NORMAL. EXPECT ANOTHER ROUND OF NUMEROUS CONVECTIVE COVERAGE DEVELOPING TUE AS THE MOIST...UNSTABLE AIRMASS REMAINS IN PLACE AND WEAK FRONTAL BOUNDARY DROPS INTO THE AREA. MODERATE INSTABILITY WITH NO CAP EXPECTED AGAIN. HOWEVER...DCAPE VALUES WILL LIKELY NOT BE AS HIGH AS AIRMASS MOISTENS. STILL...ISOLATED TO SCT SVR STORMS WILL BE POSSIBLE...WITH DAMAGING DOWNBURSTS THE MAIN THREAT. THE STRING OF VERY HOT TEMPS SHUD FINALLY COME TO AN END WITH HIGHS NEAR TO A COUPLE OF DEGREES BELOW NORMAL. && .SHORT TERM /TUESDAY NIGHT THROUGH THURSDAY/... AS OF 200 PM MONDAY...THE SHORT TERM WILL BE DOMINATED BY A BROAD...POSITIVELY TILTED UPR TROF EXTENDING FROM THE GREAT LAKES TO THE LWR MS VALLEY AND DOWNSTREAM NORTH ATLANTIC RIDGE. RELATIVELY WEAK FLOW ALOFT WILL REMAIN ACRS THE SE CONUS IN THIS PATTERN...KEEPING A QUASI-STATIONARY FRONTAL ZONE ORIENTED FROM SW TO NE ACRS THE REGION. COPIOUS MOISTURE WILL REMAIN WITHIN THE FRONTAL ZONE WITH PWATS IN THE 1-2 SD ABV NORMAL RANGE. AS FOR FORCING...THE GFS AND NAM SEEM TO AGREE SOMEWHAT ON SHORTWAVE ENERGY AND SOME UPR DIVERGENCE MAXIMIZED ON WEDNESDAY. A WEAK LLVL WAVE IS PROGGED TO DEVELOP ON WEDNESDAY OVER THE TN VLY AS WELL...BACKING THE FLOW TO S/SELY AND INCREASING UPSLOPE FORCING ALONG THE BLUE RIDGE. A BLEND OF THE GUIDANCE RESULTS IN VERY HIGH POPS...BASICALLY SHOTGUN LIKELY ACRS THE ENTIRE AREA. THERE SHUD STILL BE SOMEWHAT OF A DIURNAL NATURE TO POPS...BUT DEPENDING ON TIMING OF UPPER IMPULSES...THERE COULD BE DECENT COVERAGE DURING OVERNIGHT HOURS AS WELL PER INSTBY IN FCST SNDGS. IN FACT...FCST SNDGS SHOW VERY MOIST COLUMN INDICATIVE OF A HEAVY RAIN THREAT. SEVERE THREAT WILL PROBABLY BE LIMITED DUE TO THE NEAR MOIST ADIABATIC SNDGS AND WEAK SHEAR. MAX TEMPS WILL BE BELOW NORMAL FOR A CHANGE DUE TO CLOUDS AND PRECIP...AND MIN TEMPS WILL BE NEAR NORMAL. && .LONG TERM /THURSDAY NIGHT THROUGH MONDAY/... AS OF 215 PM MONDAY...THE GOOD AGREEMENT AMONGST THE DETERMINISTIC MODELS AND LITTLE SPREAD IN GEFS SUGGEST ABOVE AVERAGE CONFIDENCE IN MEDIUM RANGE FCST. SUBTROPICAL RIDGE WILL REMAIN ANCHORED OFF THE EAST COAST...BUT AMPLIFIES...PUSHING A FRONTAL BNDRY BACK NORTH FOR THIS WEEKEND. LLVL FLOW WILL REMAIN SELY...AND PWATS 2 STANDARD DEVIATIONS ABV NORMAL. SO CONTINUED UNSETTLED WEATHER IS PROGGED THRU NEW DAY 7. GIVEN SUCH A PROTRACTED PERIOD OF HIGH POPS...HYDRO CONCERNS MAY INCREASE...ESPECIALLY IN UPSLOPE AREAS. OVERALL...THERE IS NO PERIOD WHERE UPR FORCING IS ALL THAT STRONG...AND 850MB MOISTURE FLUX REMAINS MODEST AT BEST...WHILE MOISTURE PLUME/PWAT ANOMALIES SHIFTS WEST OF THE CWFA (PER THE 12Z GEFS). SO WILL NOT ADD ANY HYDRO MENTION IN THE HWO ATTM. EXPECTING LESS CLOUD COVER AND A WARMING TEMP TREND AS UPR RIDGE REASSERTS ITSELF THRU THE WEEKEND. && .AVIATION /19Z MONDAY THROUGH SATURDAY/... AT KCLT...CONVECTION GOING A LITTLE SOONER THAN EXPECTED OVER THE PIEDMONT. THIS LIKELY DUE TO THE CONVERGENCE BOUNDARY NEAR THE AREA. IN LINE WITH THE NEW TAF RULES...HAVE PREVAILING VFR TS IN THE TAF BEGINNING AT 20Z GIVEN THE CONVECTION NEAR THE AIRFIELD. EVEN THIS MAY BE TOO SLOW...BUT WILL AMD AS CELLS APPROACH. NUMEROUS CONVECTION WILL LINGER INTO THE EVENING...WITH SCT CONVECTION POSSIBLE MUCH OF THE NIGHT. THEREFORE...HAVE GONE WITH PREVAILING VFR TS THRU 04Z AND PROB30 THEREAFTER. EXPECT THAT ANY RESTRICTIONS WILL BE LIMITED TO CONVECTIVE CELLS...SO THE FCST IF VFR THROUGHOUT. IF CONVECTION TAPERS OFF OVERNIGHT AND SKIES CLEAR...THEN FOG WOULD BE POSSIBLE. EXPECT CONVECTION TO GET GOING EARLY AGAIN TUE WITH MOIST UNSTABLE AIR MASS AND WEAK FRONT DROPPING INTO THE AREA...HENCE THE PREVAILING TS BY NOON. N TO NW WIND WILL CONTINUE THRU THE PERIOD XCPT FOR VARIABLE AND GUSTY NEAR TS. ELSEWHERE...EXPECT A SIMILAR EVOLUTION COMPARED TO KCLT. THE MAIN EXCEPTION IS AN EARLIER ONSET AT ALL BUT KAND. IN ADDITION...WINDS WILL BE MORE WLY FOR THE SC SITES THRU THE AFTERNOON...THEN N TO NE OVERNIGHT AND TUE. FOG MORE LIKELY AT KAVL/KHKY...BUT COULD DEVELOP ANYWHERE CONVECTION TAPERS OFF AND SKIES CLEAR. OUTLOOK...SHRA/TSRA AREA EXPECTED TO BECOME NUMEROUS TUESDAY AFTERNOON AND AGAIN ON WEDNESDAY WITH A STALLED FRONT ACROSS THE CAROLINAS AND A WEAK UPPER TROUGH TO OUR WEST. THIS WILL BRING OCCASIONAL MVFR/IFR RESTRICTIONS AROUND STORMS. AREAS OF MORNING FOG/STRATUS ARE POSSIBLE...ESP IN THE MTN VALLEYS AND WHERE RAIN FALLS.
